A Changing Environment where the Sun Don’t Shine

Dr. John Bruno introduced me to NOAA’s Coral Reef Watch website last year.  It’s a online tool for tracking global sea surface temperature data in real-time. But, really, all you need is an affinity for color scales to find it useful. Reddish areas on the map mean corals beware; temperatures are unusually high. For sleep deprived master’s students, pretty colors are easier on the eyes that plotted regressions.

But what about temperatures, say, a quarter mile beneath the surface?  There are no user-friendly websites or pretty maps for tracking anomalous temperatures in deeper waters. Little light reaches to this depth and it is nearly impossible for satellites to gather data. Perhaps that’s why awareness of climate-induced changes in the mesopelagic environment is only recently gaining ground.

Last week, NPR’s Science Friday hosted Dr. William Gilly of Stanford’s Hopkins Marine Lab. His lab is investigating the recent population increase and geographic spread of the deep-water  Humbolt Squid up the California coast. This tropical jumbo-sized squid has even been spotted in Sitka, Alaska!

Why are there more and why are they moving? One theory suggests that their mesopelagic habitat is changing, and the squid are following new temperature and oxygen gradients. New science does conclude that oxygen levels off California are changing at about 1000m depth. But very little is known about how mesopelagic creatures are responding

The full NPR interview is worth a listen for those of you interested in new indicators of mesopelagic environmental change. The deep deserves attention, too.

New study indicates sea level can rise 1 m in 50 years

A new study published in Science this week (Dorale et al 2010) indicates sea level can rise extremely quickly, as fast as “Twenty meters per thousand years [which] equates to one meter of sea level change in a 50-year period,” according to lead author Jeffrey Dorale, an assistant professor of geoscience at the University of Iowa. “Today, over one-third of the world’s population lives within 60 miles of the coastline. Many of these areas are low-lying and would be significantly altered—devastated—by a meter of sea level rise. Our findings demonstrate that changes of this magnitude can happen naturally on the timescale of a human lifetime. Sea level change is a very big deal.”

Something very unusual happened about 80,000 years ago, as Earth’s last ice age was getting started. Sea levels that had been dropping for thousands of years–as more and more water became trapped in expanding glaciers–suddenly rose, according to a new study. Then after a few thousand years, the levels fell again. Although the researchers haven’t found the cause of this phenomenon, they say the findings could force at least a partial rethinking of the mechanisms governing Earth’s climate.

In coastal caves on the Spanish island of Mallorca in the Mediterranean Sea, the team studied stalactites encrusted with calcite. They measured the elevation of those encrustations, which were deposited like bathtub rings that mark high- and low-water levels, and then dated those deposits using the radioactive decay of traces of uranium into thorium isotopes. Based on those calculations, the researchers found that sea level 80,000 years ago had rebounded to the point where it rose 1 meter higher than it is today. And it could have risen quite quickly, as much as 2 meters per century, says geochemist and lead author Jeffrey Dorale of the University of Iowa, Iowa City.

New AIMS report on climate change and the tropical marine environment

AIMS has issued an easy to read white paper on its home page, outlining its major findings related to coral reefs and climate change.  This was apparently added on Dec 19, 2009 the same day as Jamie Walker’s “How the reef became blue again” piece in The Australian.  Coincidence?   I’ll excerpt some highlights below:

Climate change and the tropical marine environment

Tropical marine environments such as coral reefs and mangrove forests around the world are under unprecedented pressure due to climate change, changes in water quality from terrestrial runoff and overexploitation. Coral reefs are iconic tropical ecosystems represented by Australia’s irreplaceable Great Barrier Reef (GBR) and the less explored reefs off Western Australia. Corals thrive in locations which also happen to be near their physiological limits, making them sensitive to stresses caused by rising sea surface temperature and an increase in ocean acidity linked to rising carbon dioxide (CO2) in the atmosphere.

What we know

  • The long-term average temperature for the waters of the Great Barrier Reef has increased by about 0.4oC since the 19th century and the Reef system has experienced two mass coral bleaching events (1998 and 2002) caused by long periods of coral exposure to unusually warm seawater.
  • During the 1998 coral bleaching event, 42 per cent of shallow water coral reefs on the GBR bleached and an estimated 2 per cent died that year. This equates to approximately 400km2 of reef area.
  • In 2002, the largest bleaching event on record, an even greater proportion of the Reef bleached (55 per cent) and an estimated 5 per cent died. This equates to approximately 1000km2 of reef area
  • While these percentages may seem small, they can be localised and severe events.
  • Some local extinctions of coral species in several parts of the Great Barrier Reef have been observed and appear to be linked to higher sea surface temperatures causing coral bleaching.
  • Coral bleaching was again observed in the 2006 summer, particularly in the southern GBR, where local water temperatures reached around 1-2oC above the seasonal average.
  • Coral reefs may take 10 to 20 years to recover from serious bleaching events that cause coral death.
  • The amount of CO2 in the atmosphere is known to be increasing and the extra CO2does not stay just in the atmosphere with a significant amount dissolving into the ocean. The pathways it then follow under different conditions and the consequences of its accumulation in different environments is under-researched. Some scientists have proposed that the large portion of CO2 that is entering the ocean from the atmosphere is causing a shift downwards in seawater pH, making it more acidic.
  • A growing body of experimental evidence is showing that seawater acidified to mimic potential future scenarios significantly impacts upon the health of some fish and coral species. There are many millions of species in the ocean and each will have different sensitivities to acidification and respond in different ways. No single species lives in isolation and how the effects seen at an individual species level translate to an ecosystem response is not understood. It has been speculated that acidified seawater may alter the makeup of marine ecosystems and weaken coral reef structures.
  • It is known that heat stress causes corals to expel the symbiotic algae they host in their tissues. What is not sufficiently understood are the numerous mechanisms that may enable corals to adapt to new, warmer and potentially acidic conditions.
  • Based on observations of an increase in hurricane and cyclone events in recent decades, even more severe storms and cyclones have been proposed to occur as our climate changes, though this remains a topic of debate.

The consequences of increasing atmospheric carbon dioxide

The amount of CO2 in the atmosphere has risen to the current level of 383 parts per million (ppm) from about 200 ppm in the days before the Industrial Revolution more than 200 years ago. Measurements of atmospheric CO2 taken from AIMS headquarters outside Townsville show broad agreement with this global figure (see page 1 of this document).

Under current IPCC projections and assuming no measures are adopted to reduce CO2emissions, atmospheric CO2 concentrations are likely to reach 500 ppm in the second half of this century. If that is the case, global temperature averages may increase a further 2oC and possibly more.

Coral reefs provide ecosystem services essential to our national identity and wealth. The GBR contributes more than $5 billion annually to the Australian economy.

While Australia’s coral reefs are well managed, they are not isolated from global atmospheric and ocean changes.

Barrier Reef still vulnerable says AIMS CEO Ian Poiner

The Australian recently published a letter from AIMS CEO Dr. Ian Poiner (only online as far as I can tell) written in response to Jamie Walker’s reef wipeout story.  See our coverage of this debacle here, here and here.

This year the Australian Institute of Marine Science has observed that there is no mass coral bleaching on the southern Great Barrier Reef. Your story (“Report undercuts PM’s reef wipeout”, 3/2) uses these observations to contradict the view that the reef is threatened by climate change. This is not the case. The Great Barrier Reef is one of the healthiest coral reef ecosystems in the world, but climate change is a significant long-term threat. Coral reefs exist in locations that are near their physiological limits, making them especially sensitive to stresses caused by rising sea surface temperature and ocean acidity.

The GBR has already experienced two mass coral bleaching events (1998 and 2002), during which hundreds of square kilometres of reef died. While the reef has shown capacity to recover from mass bleaching, the frequency and scale of such events have a significant bearing on the likelihood of recovery. Frequency and scale are directly related to rising sea surface temperatures and there is ample evidence of warming waters on the Great Barrier Reef.

One or two seasons of no bleaching do not mean that the GBR is not threatened. It is over-generalisation to the point of unreality to extrapolate from one set of observations to what is going to happen to the GBR in the long term.

Warming spurs U.S. to consider ESA protection for 82 coral species

Not sure I agree with this strategy or in the science behind it, but I heard this was coming.  The EPA is considering whether to list 82 new coral species in US Waters as threatened or endangered.  Acropora palmata and Acropora cervicornis were listed as vulnerable under the Endangered Species Act in May 2006.

From the Federal Register (Vol. 75, No. 27 / Wednesday, February 10, 2010)

Endangered and Threatened Wildlife; Notice of 90–Day Finding on a Petition to List 83 Species of Corals as Threatened or Endangered Under the Endangered Species Act (ESA)

AGENCY: National Marine Fisheries Service (NMFS), National Oceanic and Atmospheric Administration (NOAA), Department of Commerce.

ACTION: 90–day petition finding; request for information.

SUMMARY: We (NMFS) announce a 90– day finding on a petition to list 83 species of corals as threatened or endangered under the ESA. We find that the petition presents substantial scientific or commercial information indicating that the petitioned actions may be warranted for 82 species; we find that the petition fails to present substantial scientific or commercial information indicating that the petitioned action may be warranted for Oculina varicosa. Therefore, we initiate status reviews of 82 species of corals to determine if listing under the ESA is warranted. To ensure these status reviews are comprehensive, we solicit scientific and commercial information regarding these coral species.

DATES: Information and comments must be submitted to NMFS by April 12, 2010.

The 83 species included in the petition are: Acanthastrea brevis, Acanthastrea hemprichii, Acanthastrea ishigakiensis, Acanthastrea regularis, Acropora aculeus, Acropora acuminate, Acropora aspera, Acropora dendrum, Acropora donei, Acropora globiceps, Acropora horrida, Acropora jacquelineae, Acropora listeri, Acropora lokani, Acropora microclados, Acropora palmerae, Acropora paniculata, Acropora pharaonis, Acropora polystoma, Acropora retusa, Acropora rudis, Acropora speciosa, Acropora striata, Acropora tenella, Acropora vaughani, Acropora verweyi, Agaricia lamarcki, Alveopora allingi, Alveopora fenestrate, Alveopora verrilliana, Anacropora puertogalerae, Anacropora spinosa, Astreopora cucullata, Barabattoia laddi, Caulastrea echinulata, Cyphastrea agassizi, Cyphastrea ocellina, Dendrogyra cylindrus, Dichocoenia stokesii, Euphyllia cristata, Euphyllia paraancora, Euphyllia paradivisa, Galaxea astreata, Heliopora coerulea, Isopora crateriformis, Isopora cuneata, Leptoseris incrustans, Leptoseris yabei, Millepora foveolata, Millepora tuberosa, Montastraea annularis, Montastraea faveolata, Montastraea franksi, Montipora angulata, Montipora australiensis, Montipora calcarea, Montipora caliculata, Montipora dilatata, Montipora flabellata, Montipora lobulata, Montipora patula, Mycetophyllia ferox, Oculina varicosa, Pachyseris rugosa, Pavona bipartite, Pavona cactus, Pavona decussate, Pavona diffluens, Pavona venosa, Pectinia alcicornis, Physogyra lichtensteini, Pocillopora danae, Pocillopora elegans, Porites horizontalata, Porites napopora, Porites nigrescens, Porites pukoensis, Psammocora stellata, Seriatopora aculeata, Turbinaria mesenterina, Turbinaria peltata, Turbinaria reniformis, and Turbinaria stellula. Eight of the petitioned species are in the Caribbean and belong to the following families: Agaricidae (1); Faviidae (3); Meandrinidae (2); Mussidae (1); Oculinidae (1).

The petition states that all of these species are classified as vulnerable (76 species), endangered (six species: Acropora rudis, Anacropora spinosa, Montipora dilatata, Montastraea annularis, M. faveolata, Millepora tuberosa), or critically endangered (one species: Porites pukoensis) by the World Conservation Union (IUCN). Montipora dilatata and Oculina varicosa are also on our Species of Concern list.

BY Allison Winter, E&E reporter

Published February 11, 2010, link to the original story here

The Obama administration will consider federal protection for 82 coral species threatened by warming water temperatures.

The National Marine Fisheries Service said yesterday that it has found “substantial scientific or commercial information” that Caribbean and Indo-Pacific corals may be threatened or endangered. Environmentalists have predicted the corals — found near Florida, Hawaii and U.S. territories — could be wiped out by midcentury if the government does not take steps to protect them from warming waters, rising ocean acidity and pollution.

The announcement in yesterday’s Federal Register launches a formal status review by federal biologists. The fisheries service will also accept public comment before deciding next year on whether to list the corals under the Endangered Species Act.

“The status review is an important step forward in protecting coral reefs, which scientists have warned may be the first worldwide ecosystem to collapse due to global warming,” said Miyoko Sakashita, oceans director at the nonprofit Center for Biological Diversity. “Endangered Species Act protection can provide a safety net for corals on the brink of extinction.”

The center asked the fisheries service last year to protect corals and threatened to sue the agency last month if it failed to act.

All of the species under consideration have seen population declines of at least 30 percent over 30 years, according to the center.

The group’s petition blamed myriad threats for the corals’ decline: ocean warming and acidification, shipping-channel dredging, coastal development, pollution from agriculture and development, disease, predation, reef fishing, marine debris, invasive species, aquarium trade, and damage from boats and anchors.

In the service’s finding yesterday, biologists agreed that the coral populations are at risk of collapse without recovery, given the population decline that has occurred already and mounting threats.

If the corals are protected as endangered species, it would be illegal to harm or kill the species. That could open commercial fishers, farmers and all the other industries cited in the petition to federal regulation or lawsuits from environmentalists. A “threatened” listing could be less restrictive. The fisheries service would write regulations to protect the corals.

The government now lists two Atlantic coral species, elkhorn and staghorn, as “threatened” due to disease, warming sea temperatures and hurricane damage.

The center had sought a listing for 83 species, but the government left one out of its proposal. The fisheries service said there was not enough evidence to consider a listing for the ivory tree coral, or Oculina varicosa. The ivory tree coral lives in shallow water from Florida to North Carolina and off Bermuda and the West Indies.

More details from the Register:

The petition states that all of these species are classified as vulnerable (76 species), endangered (six species: Acropora rudis, Anacropora spinosa, Montipora dilatata, Montastraea annularis, M. faveolata, Millepora tuberosa), or critically endangered (one species: Porites pukoensis) by the World Conservation Union (IUCN). Montipora dilatata and Oculina varicosa are also on our Species of Concern list.

Under the ESA, a listing determination may address a ‘‘species,’’ which is defined to also include subspecies and, for any vertebrate species, a distinct population segment which interbreeds when mature (DPS) (16 U.S.C. 1532(16)). Because corals are invertebrate species, we are limited to assessing the status of species or subspecies of corals. A species or subspecies is ‘‘endangered’’ if it is in danger of extinction throughout all or a significant portion of its range, and ‘‘threatened’’ if it is likely to become endangered within the foreseeable future throughout all or a significant portion of its range (ESA sections 3(6) and 3(20), respectively, 16 U.S.C. 1532(6) and (20)).

Of the 83 petitioned species, eight species occur in the U.S. waters of the Caribbean, and 75 occur in the U.S. waters of the Indo-Pacific. The petition includes species accounts (i.e., description of the species’ morphology, life history, habitat, distribution, and loss estimates over 30 years (20 years into the past and 10 years into the future)) of each of the 83 species, threats facing each species, and descriptions of the status of coral reef ecosystems of the wider Caribbean and Indo-Pacific areas. The petition asserts that all of the petitioned species have suffered population reductions of at least 30 percent over a 30–year period, relying on information from the IUCN.

Eight of the petitioned species occur in the Caribbean, and 75 in the Indo-Pacific.

Caribbean species include Agaricia lamarcki, Dendrogyra cylindrus, Dichocoenia stokesii, Montastraea annularis, Montastraea faveolata, and Montastraea franksii.

I agree there is sound evidence that these species have declined substantially (perhaps by 30% in relative terms) across the broader Caribbean over the last several decades.  Yet note a key to this petition passing the smile test is that each species has to have been found to have declined in US waters, which in the Caribbean, isn’t a lot of habitat.  The thing that has always bugged me about this approach, well one thing, is that although a coral species may have declined by 30% or more, there are in some cases literally tens or hundreds of millions of colonies throughout the species’ ranges. Thus it seems a stretch to suggest they are threatened with literal extinction.

Another is that I think this misses the point of coral conservation; which from my perspective is to restore or maximize coral cover.  As I argued in 2001 (Bruno and Bertness 2001) it would be pretty easy to protect populations of foundation species (i.e., habitat-forming species) without actually conserving their ecological function. Which is I think a weakness of the US Endangered Species Act.

The Caribbean, according to the petitioner, has the largest proportion of corals classified as being in one of the high extinction risk categories by the IUCN. The petitioner asserts that the region suffered massive losses of corals in response to climate-related events of 2005 including a record-breaking series of 26 tropical storms and elevated ocean water temperatures.,

This is a dubious argument, not supported by any peer-reviewed science.  IMO the losses caused by warming-bleaching were very isolated and modest in general, despite greater losses on some individual reefs.

Further, the petitioner asserts that the U.S. Virgin Islands lost 51.5 percent of live coral cover,

I very much doubt this and have seen evidence that contradicts this suggestion.  Most of the loss of live coral cover in the USVI appears to have occurred in 1989 and 1999 (Edmunds and Elahi 2007-see the figure below).  I also assume the values are relative coral cover, rather than absolute values, i.e., coral cover could have declined from %4 to 2% and this would be described as a “%50” loss.

Long-term trends in coral community dynamics on a reef at 9-m depth at Yawzi Point, St. John, U.S. Virgin Islands. (A) Percentage of coral cover at each survey period between March 1988 and August 2003.

The petitioner cites Gardner et al. (2003) in asserting that, over the three decades prior to the 2005 events, Caribbean reefs had already suffered an 80 percent decline in hard coral cover, from an average of 50 percent to an average of 10 percent throughout the region.

True, Gardner at al. 2003 does say/find this, but again, note the use of relative %loss values.  Also, we have a paper in press at MEPS (Schutte et al. 2010) that indicates Caribbean mean coral cover is closer to 20% (excluding the very low coral cover FL Keys) and has not noticibly declined since the mid-1980s. But perhaps this is quibbling. There is no doubt coral cover has declined. I just think there could be some exaggeration in the petition. Given what we have seen happening in the media recently, e.g., the IPCC reports, scientists should be really careful about the accuracy of their doom-and-gloom stories.

The abundance and trend information presented by the petitioner for each species is limited to an estimate of the percentage loss of its habitat and/or population over a 30–year period (including 20 years into the past and 10 years into the future), as assessed by the IUCN. However, the petition also asserts that these corals face significant threats. To support this assertion, the petitioner cites Alvarez-Filip et al. (2009) in noting the dramatic decline of the three- dimensional complexity of Caribbean reefs over the past 40 years, resulting in a phase shift from a coral-dominated ecosystem to fleshy macroalgal overgrowth in reef systems across the Caribbean.

We clearly showed this was not true in Bruno et al. 2009.  Very few reefs in the world are truly dominated by macroalgae in any meaningful sense.

Seventy-five percent of the world’s coral reefs can be found in the Indo- Pacific, which stretches from the Indonesian island of Sumatra in the west to French Polynesia in the east (Bruno and Selig (2007), as cited by the petitioner). As recently as 1,000 to 100 years ago, this region averaged about 50 percent coral cover, but 20–50 percent of that total has been lost, according to the petitioner. The petitioner cites Bruno and Selig (2007), stating that regional total coral cover averaged 42.5 percent during the early 1980s, 36.1 percent in 1995, and 22.1 percent in 2003.

Now this, as they say here in Oz, is some dodgy science!

The petition focuses on habitat threats, asserting that the habitat of the petitioned coral species, and indeed all reef-building coral species, is under threat from several processes linked to anthropogenic greenhouse gas emissions, including increasing seawater temperatures, increasing ocean acidification, increasing storm intensities, changes in precipitation, and sea-level rise. The petition also asserts that these global habitat threats are exacerbated by local habitat threats posed by ship traffic, dredging, coastal development, pollution, and agricultural and land use practices that increase sedimentation and nutrient- loading.

There’s no denying climate change scientists are being overwhelmed by the sceptics

Amen. That is precisely how I feel. Overwhelmed and outgunned. Still, this great editorial by veteran ABC producer and reporter Jonathan Holmes of Media Watch is uplifting.  The only thing I think he got wrong was to suggest Andrew Bolt “knows far more about the science than most other journalists, environment reporters included”. Bolt has certainly been very vocal in the debate and is making a comfortable living disparaging the science and scientists. But almost entirely by spewing misinformed nonsense that he picks up on denier blogs. See Bolt’s silly response to Jonathan’s piece here.

Journalists weather the changing climate

Link to the original editorial here.

Just a few years ago, when I was making programs about climate change policy for Four Corners, it was legitimate for journalists to argue that the science of climate change was settled. The issue was what should and could be done about it.

Boy, has the climate changed!

There’s no denying that the climate change deniers, or sceptics, (the term you prefer depends which side you’re on) have succeeded, to a degree that orthodox climate scientists find baffling, in persuading a large proportion of the public that the science of global warming is, in the Opposition leader’s words, “absolute crap”.

An even larger number of folk apparently take the view that there is so much doubt around the science that to take action that would be in any way painful is premature.

It’s true that the failure of Copenhagen has made it hard to argue that Australia should take drastic action on its own. But that was a political failure. It had nothing to do with the science.

It’s true that some stupid exaggerations, unsupported by peer-reviewed science, have been identified in the 2007 IPCC report. They’ve done a lot of harm to its credibility.

It’s true leaked emails from the Climate Research Unit of the University of East Anglia have exposed a disturbing unwillingness on the part of its scientists to share raw data, and apparent attempts by them to prevent sceptical views from being published in reputable journals.

But the vast majority of climate scientists (and for that matter, of scientists in other relevant disciplines), supported by the vast preponderance of peer-reviewed research, still maintain that human-induced climate change is an unassailable reality: rapid global warming will continue, not just for the next hundred years, but far into the future, unless and until human beings drastically reduces the emission of greenhouse gases.

So why are their views being overwhelmed, in the public arena, by the tiny number of ‘sceptics’ with scientific credentials, and their non-scientist supporters?

The simple answer, it seems to me, is that it’s been the doubters who’ve had the passion, and the commitment.

Think what you will of the Herald Sun’s Andrew Bolt, he’s industrious. He starts posting on his blog at around 6:00am, and his last posts are often past midnight. If there’s truth in Annabel Crabb’s famous observation that he cherry-picks articles from the University of East Bumcrack, he does so repeatedly, and obsessively, and to his growing army of devoted fans, convincingly. He’s made global warming his specialty. He knows far more about the science than most other journalists, environment reporters included.

He’s supported by the usual army of conservative columnists. The Devines and Pearsons and Albrechtsens and Akermans, with barely a science degree between them, have been able to satisfy themselves that a global scientific consensus is in fact a global political conspiracy, fuelled by capitalist-hating greenies.

The opinion pages – and as we showed on Media Watch last Monday, sometimes the news pages – of our only national broadsheet have heavily favoured sceptics over proponents of the scientific consensus.

Far more influential, I would guess, are the commercial radio talk back hosts. At least half a dozen of the most influential have been enthusiastically espousing the sceptic cause for years.

After all, it meshes perfectly with the general message that makes talk-back radio work for its audience, which goes roughly like this: “The politicians/bureaucrats/bosses are idiots or scoundrels. They pretend this problem (any problem) is complicated when it couldn’t be more simple. You and I can see the answer. Blind Freddie can see the answer. But they can’t because they’re stuck in their ivory towers/on the take/too clever by half/out to take your money from you.”

As we said on last week, these gentlemen (and they are all men) don’t like to trouble their listeners with both sides of a question. The proponents of global warming science (such as they are) seldom get a guernsey on their shows. The Lord Moncktons of this world get literally hours of unopposed air time.

And their listeners, as anyone who argues against them in public knows, are vociferous and passionate. Just look at the posts at the bottom of this article.

Lastly, of course, there’s the simple fact that people would rather believe those who tell them “she’ll be right,” than those who tell them their way of life is leading the world to hell in a hand-basket.

Of course, the mainstream media (with the notable exception of The Australian) has reported climate change science extensively, and on the whole, uncritically. The sceptics are quite right about that.

But reporting scientific findings, and convincing people they are true, are two different things. If the public is to be galvanised, the science needs selling. But where are the salespeople? Who has been out there arguing passionately and compellingly that climate change is real, and urgent?

As everyone agrees, the Prime Minister has been missing in action for a year or more. His minister, Penny Wong, is robotic. Peter Garrett has been sidelined. Only Greg Combet has summoned up any discernible passion on the topic.

There’s Bob Brown and his Green cohort, who preach strictly to the converted. And Malcolm Turnbull, whose sermons are magnificent; except that nobody’s listening to him any more.

The scientists themselves can’t be expected to do the job. Very few have a talent for public advocacy. It’s not their role.

They know that winning a public argument on television or radio, where there’s little time for anything but assertion on either side, has little to do with the ability to compile and assess evidence in the field, or meticulously to program computer simulations that attempt to predict the future.

They’ve been reluctant, too, to dignify people they regard as cranks or self-serving controversialists by taking them on in public debate.

And, as that debate has become more and more stridently political, they’ve been even less inclined to get embroiled.

So it’s no coincidence that the most compelling public arguments for the reality of global warming have been made by people who aren’t themselves climate scientists: people like former US vice-president Al Gore, or mammal palaeontologist Tim Flannery, or ‘public intellectuals’ like Robert Manne.

But Al Gore is a long way away, and Flannery’s been pretty quiet of late.

NGOs like Greenpeace and WWF have plenty of passion, but they’ve produced no public advocate who’s really broken through. Perhaps the Australia Institute’s Clive Hamilton has come nearest, but he’s hardly a household name outside the chatterati.

Our left-wing columnists, like Phillip Adams and Mike Carlton, have no pretensions to detailed knowledge of the science. Our environmental and science journalists largely stick to news reporting and avoid advocacy.

What we don’t have in Australia – have never had – is someone like The Guardian’s George Monbiot: a journalist with the same access to the mainstream as Andrew Bolt, who has made it his or her business to be as thoroughly on top of climate change science, and who’s willing to mix it with the sceptics at any and every opportunity.

It may have made little difference. Rationality doesn’t necessarily win arguments like this. Yet it still feels to me as though the pass has been sold without a fight.

Of course, it may turn out that the sceptics are right. In twenty years time we may all be laughing at the great global warming scare, as we do now at Y2K.

If that happens, the scientists, and the journalists who accepted their findings, will have a lot to answer for, and the sceptics will have every right to crow.

But if the opposite is true, and we find ourselves facing climate change that by then can’t be reversed before much of this continent becomes uninhabitable, it will be small comfort to be able to blame the sceptics.

If the science is as compelling as the climate change advocates would have us believe, then this was an argument that should have been won long ago. For want of champions, it’s perilously close to being lost.

Graham Readfearn-Monckton slayer-resigns from the Courier Mail

Graham Readfearn has resigned as an environmental reporter at the Courier Mail. Graham has run a number of stories and editorials about climate change, such as this great post where he gives The Australian a spanking over their continued dodgy coverage of climate change science (which ill include in full below).

He also recently debated the infamous duo of Monkton and Plimer at UQ and was asked if the coverage of that event by his paper motivated his departure.

Earlier today, I got a call from a journalist at the Sydney Morning Herald asking me if I had resigned because of the way my now former employer, The Courier-Mail, had reported the story about the high-profile climate change debate in Brisbane. My honest answer was that it wasn’t.

THIS IS HOW THE STORY WAS COVERED:

LORD Christopher Monckton, imperious and articulate, won yesterday’s climate change debate in straight sets.

Forget facts and fictions, numbers and statistics, this British high priest of climate change sceptics is a polished performer, even against the most committed of scientists.  Aided by Adelaide’s Professor Ian Plimer, Lord Monckton cruised to victory before a partisan crowd of suits and ties, movers and shakers.

There’s very little to say, in fact, about the debate at the Brisbane Institute. I’m not claiming victory, because there was no contest in the first place. Both Professor Plimer and Lord Monckton repeated all their well-rehearsed pseudo-science. In a room full of supporters, it’s hardly surprising their rhetoric was cheered.

But as a journalist or a commentator, going to Lord Monckton and Professor Plimer for a view on climate change is akin to asking the Faroe Islands soccer team if the Australian cricket captain’s training regime is good enough to win them the Ashes.

Monckton and Plimer are clearly the Faroe Islands soccer team (apologies to FIFA) of the climate change advisory industry. Neither have published a single peer-reviewed article on anthropogenic climate change and every science academy in the world disagrees with the thrust of their argument. Their errors are continually pointed out from credible scientists, but they repeat those errors, ad nauseam.

As I said to people in the audience, if they choose to buy their climate science from non-qualified sources continually shown to be incorrect, then that’s their choice. It would make an interesting psychology study to understand their willingness to accept such views.

As for how the climate change issue is being reported in some quarters, I’ve made my thoughts pretty clear on that too.

Why our leading climatologist won’t talk to The Australian any more

Graham Readfearn

ANOTHER day, another predictable and regurgitated dog’s brekky of a climate change editorial from The Australian.

This time, The Australian gives a virologist and computer modeller a turn at being a climate change expert.

Before we get to the real shocking part of this story (and please pardon me for keeping you in suspense until the end, but it’s worth it so hang on in there) let’s first look at just a couple of the assertions made by Jon Jenkins, the aforementioned virologist.

“…prior to the 1970s, surface-based temperatures from a few indiscriminate, mostly backyard locations in Europe and the US are fatally corrupted and not in any sense a real record.’’

Mr Jenkins doesn’t say where he gets this stunning conclusion from, but it’s fair to say he is ignorant of Australia’s network of more than 100 land-based thermometers which provide our Bureau of Meteorology with its records.

Next, Mr Jenkins states confidently how satellite measurements are the only ones which count, which he says started in the 1970s (actually, they started in 1979, so he was only just right). He then claims they only reveal “minuscule warming” which stopped in 2000 and had completely reversed by 2008.

This one simple graph shows how wrong he is. Below is a chart which plots all the four major global temperature records against each other – two of which use satellite data (RSS and UAH) and the other two (GISS and HadCRU) land-based measurements.

Thanks to the Yale Forum on Climate Change & the Media for this graph.

So what of these accusations from Jenkins? I asked Australia’s acting chief climatologist Dr Michael Coughlan at the Bureau of Meteorology for his view.

“It’s nonsense,’’ says Coughlan.”No matter how you cut the cloth, the temperatures are going up.’’

Coughlan was one of two review editors for the Australian chapters of the latest IPCC report. So what does he make of one of Jenkins other accusations – that the IPCC is a clique?

“My job was not to write the report, but to make sure that the authors who were writing it had paid attention and responded to the comments from other scientists. That included all the sceptics that we could find. They were given the opportunity to comment, but many chose not to.’’

Of climate change contrarians such as Jon Jenkins, Coughlan has this to say.

“We have produced rebuttals of all of these arguments – they have all been addressed. But they just keep trotting them out. No matter how many times you tell them they’re wrong, they just keep going. The general approach seems to be – if we keep banging away at an untruth, people will start to believe it’’.

Let’s not forget that these contrarian views are not being expressed on a bit of street press or some fringe web site somewhere – they’re being repeated over and over in Australia’s only national newspaper. So now comes the revelation – and that is Coughlan’s view of The Australian newspaper itself.

“The Australian clearly has an editorial policy. No matter how many times the scientific community refutes these arguments, they persist in putting them out – to the point where we believe there’s little to be gained in the use of our time in responding.’’

There. Told you it was worth waiting for.

Jamie Walker’s response to Media Watch

Editorial writer, AKA “journalist” for The Australian Jamie Walker has responded to reports (e.g., see the coverage by Media Watch here) of inaccuracies in his piece last week on the GBR and climate change.  We noted many of these problems and the broader media is now taking a second look at Jamie’s work and the editorial policies of The Australian.  (For those of you living outside Oz, The Australian is a local Murdoch/NewsCorp-owned right-leaning paper.)

Reporters, particularly working for Murdoch/NewsCorp vehicles such as Fox News, regularly lie about the science of climate change.  (see the roundup on this over at Media Matters here).  There are countless newspaper “reporters” whose writing is driven largely by their political ideology, e.g., see George Will.  Such denial of fact and science is harmful to society.  But it is usually restricted to the editorial pages where ideologues of all varieties are free to spout off and help sell newspapers. What is so surprising about Jamie’s GBR story is that it was clearly a barely disguised editorial published on the front page as a regular news story.   Jamie has now admitted as much in a letter to the paper’s editor (see below), saying that the main point of the article was based merely on his opinion.  What disciplinary action the paper will take or what internal editorial policy changes will occur are unclear.  As is typically the case, the repsonsibility lies as much with the editor  Paul Whittaker himself for deciding to put the piece on the front page as a “news item” rather than on the editorial page where opinion-based articles belong.  Yet Whittaker is also the one responsible for disciplining Walker and to do so would be an admission of fault and an acceptance of responsibility.

This same issue has flared up again and again in the MSM, e.g., see the well-covered examples in the Washington Post, where editorial page editor Fred Hiatt has gotten hammered (also see here) over allowing George Will to publish nonsense about climate change.  Yet an important difference is that even the WaPost restricts such foolishness to the editorial section.  The papers serious reporters regularly contradict and correct Will’s false claims.  Due to their ideological alignment and the conflict of interest, Hiatt has never corrected any of Will’s mistakes.  Will Paul Whittaker follow suit or stand for the standards and ethics of honest and professional journalism at The Australian?

Jamie’s letter is addressed to Paul Whittaker, Editor of The Australian and starts out by citing Ove’s post about the article:

February 7, 2010

Mr Paul Whittaker Editor The Australian

Dear Paul,

Thank you for giving me the opportunity to respond to the issues raised by Media Watch. I note that the language used by the Media Watch representative is uncannily similar to that of Professor Ove Hoegh-Guldberg, who blogged on my piece last week. https://climateshifts.org/?p=4329

Then quickly gets into trouble:

A few points:

We contrasted comments by the Prime Minister against latest research findings on coral bleaching.

Scientist often wonder whether the science is really that confusing or whether biased “journalists” are purposefully confusing things.  Media Watch got this story exactly right. Jamie Walker took the AIMS report totally out of context and the inferences he made are not supported by the science or the scientists nor by logic. AIMS found that a handful of reefs on the southern GBR did not bleach as expected last summer. They explained why (storms cooled the water down).  Simple, right? Somehow Jamie took this as evidence that FUTURE global warming/increases in ocean temperature would not harm the GBR. Huh???  Do I need to explain the fallacy in that logic?  Well here is it anyway;

1) The reef didn’t warm, due to storm activity, as expected, so not much can be learned about future warming (obvious right?)

2) Even if it did warm and corals didn’t bleach, so what?  This would not have nullified the large body of science that the report Rudd was citing is based on.  It is an easy, child-like experiment.  Warm corals up in a tank by 1C and they bleach, by 3C and they die.  Questioning that this happens or would happen more frequenty if the ocean warmed by 4-6C is idiotic; it isn’t a sign of skepticism, it is instead demonstrating a striking degree of truculence and denial of establish fact.  Sometimes warmed corals in nature don’t bleach due to a variety of other factors that influence bleaching severity, e.g., the species and genotypic composition of the coral assemblage, current velocity, light, cloudiness, the recent thermal history, etc.  Scientists know this and we have considered all that in our projections of future bleaching under AGW.

3) Not a single scientist or anyone at all backed up Jamie’s faulty interpretation of the AIMS report.  In fact AIMS wrote the Australian to complain (here) that Jamie misrepresented their science and to explain why Jamie’s broader argument was flawed;  “AIMS has found that the science is pointing to potentially severe consequences for the Great Barrier Reef from climate change. Current observations of the state of the Reef this year do not contradict this.”  Neither Jamie nor The Australian have responded in print.  Since the argument is based merely on Jamie’s non-expert judgement, is it not obvious that this is editorialism rather than journalism?

Perhaps Media Watch should ask the PM’s office his sourcing: I certainly referred to the IPCC in my report, and also detailed the basis of the concern about long-term bleaching of the reef.

The story said Mr Rudd’s assertions “grate with’’ the findings that the reef was likely to escape bleaching, again, this year; it did not say it undermined the “view’’ that global warming could destroy the Great Barrier Reef.

The point here is unclear (the writing is tortured), but I think Jamie is suggesting that the main point of his article was not to cast doubt on whether AGW is a threat to the GBR and coral reef in general.  Really?

Rudd’s “assertion”, i.e., communication of published findings by scientists, does not “grate” / contradict the finding that last year, a handful of reefs didn’t bleach as expected. Magic Johnson has lived with HIV for 19 years, but that doesn’t “grate” against the fact that HIV is a human travesty or predictions that it will kill millions of people in the future.  [Although given the lack of warming on the reefs in question, the more appropriate analogy would be to argue that a guy who didn’t contract HIV and didn’t die from AIDS was proof that HIV-AIDS is not a threat]

I “could’’ get hit by a bus tomorrow; that does not mean this will happen.

True, but I doubt Jamie walks into the street without looking both ways, i.e., he applies the precautionary principle to avoid a bad outcome.

Furthermore, Jamie seems to be portraying the science here as mere speculation; imagine evil-left-wing scientists sitting in pub, dreaming up bad stuff that could happen (OK, we actually do do that).

There is concern, modelling and various projections as to how the reef could be destroyed as early as 2030 under worst case scenarios for climate change.

We are actually exceeding the “worst case scenarios” Jamie speaks of in terms of the rate of CO2 output and concentration increase, which is what the IPCC emissions scenarios are based on.  So these aren’t somehow outlandish predictions from a Hollywood movie.  They are merely the worst case, in relative terms.  I think the more conservative (and comforting to governments) emissions scenarios like the A1 are unlikely – at best – to occur.  Here are some of the assumptions underlying the A1:

The A1 scenarios are of a more integrated world. The A1 family of scenarios is characterized by:

  • Rapid economic growth.
  • A global population that reaches 9 billion in 2050 and then gradually declines.
  • The quick spread of new and efficient technologies.
  • A convergent world – income and way of life converge between regions. Extensive social and cultural interactions worldwide.

Exactly how realistic does that sound, even to an optimist?

I think, however, it is a long bow to present this outcome as a certainty.

Jamie has a right to think that or anything else.  But what he or anyone “thinks” in no way influences or questions the science at hand.  And basing a newspaper article, not clearly labeled as an editorial, on his opinions is journalistically unethical and fraudulent.

A number of senior scientists working on the reef argue this – and we quoted some of them last December.

A point on the semantics here:  if you really asked reef scientists whether “this outcome is a certainty” I suspect a large majority including me would say no.  But not because we don’t think it is highly likely.  Nearly all do.  Science never provides certainty about anything.  It only deals with probability.  Future projections are all probabilistic by nature, thus their outcome cannot by definition be “a certainty”.  Point being, if Jamie cleverly phrased the question this way, he might get honest scientists to agree “yes we are not 100% certain of this outcome”.

Also note, none of the scientists Jamie mentions were asked about the AIMS study at hand or about the inferences he took from it, as he seems to imply.   The issue now under investigation is whether Jamie misled his audience in his Feb 3 article, which took things a lot further than his article in December.  His is trying to sidestep the issue and questions about his Feb story by focusing on his earlier piece.

At that time, the Great Barrier Reef Marine Park Authority said the Great Barrier Reef had never been healthier (as per my feature article of Dec 19, 2009).

GBRMPA did not in fact state this and I have published science showing this clearly is not the case as have many other more esteemed and locally-knowledgable scientists.

This is a free country, and maintaining a healthy scepticism about doom and gloom projections about anything, including climate change, is entirely in order with engendering informed and full debate.

I fully agree.  Fair point.  But that is Jamie’s right and duty as a citizen.   As a reporter, his duty and ethical responsibility is to report the truth and not lie about or otherwise misconstrue the facts and scientific issues.

I have invited Dr Hoegh-Guldberg to be interviewed; he was to phone me at 10.30am last Friday, but didn’t. I had a response from him by email yesterday, in which he suggested it would be easier for him if I email him questions to which he will respond. I will continue to seek to interview him.

Good.  I am sure Ove and hundreds of other reef experts (and probably most of his readers) could explain why the main point of Jamie’s story was mistaken.  I mentioned to Ove last week that it would be fun to have Jamie over to UQ for lunch and beers.  Maybe we could talk some sense into him.  (But I may have killed that opportunity with this sarcastic and somewhat mean-spirited post.)

What led me to say the findings will entrench scepticism about the effects of climate change is, in part, that the Great Barrier Reef Marine Park Authority issued a publicly warning last summer that a mass coral bleaching episode on the reef was imminent, but this never happened.

I do see Jamie’s point here and I think he is correct.  The public wrongly takes short-term weather events as evidence refuting that the earth is even warming and to question forecasts of future impacts of AGW.  We have covered this phenomena recently extensively (e.g., see here and here).  But a trained, educated science reporter should know the difference between science and weather.  Here is an anecdote to hopefully illustrate the logical flaw in Jamie’s argument:  Scientists say that tobacco and alcohol  are likely to shorten your life.  My maternal grandfather “Gap” was a life-long heavy smoker and drinker, but lived well into his 80s.  Does this observation “grate” against the predictions of epidemiologists?

Perhaps Media Watch would care to explore why GBRMPA has been more circumspect this year, when conditions were broadly similar to those early in the summer of 2008-09.

Well for one, the name of the series is Media Watch not Scientist Watch.

A bit of legwork by Media Watch would have pulled up a piece The Courier-Mail published on December 19, 2009, warning that coral bleaching was likely this summer.

Right, and given the warm El Nino conditions, that is a reasonable expectation.

You can’t have it both ways, especially in the context of the issues that have emerged with the IPCC’s 2007 report on the Himalayas and Amazon rainforest.

Oh boy.  Here we go.  Emailgate, the IPCC is corrupt, the earth is really cooling, the glaciers aren’t meling… Is any more evidence needed that Jamie is a committed ideological climate change denier?

And I don’t understand what “You can’t have it both ways” refers to.

Professor Peter Ridd, who we quoted in my December articles on the reef, and who has conducted research on issues involving the reef for 25 years,

Right.  Peter Ridd.  Reef expert. See our posts here, here and here on Peter Ridd’s view of the GBR.

has said that he was concerned about scientists “crying wolf’’ over threats to the reef. This, he said, had happened in relationto the crown of thorns starfish, and projections about the impact on the reef of sedimentation and pesticide runoff.

Peter Ridd’s “concerns” and what Jamie Walker “thinks” are totally irrelevant to the issue and debate.  This is a scientific debate.  It is supposed to be based on science, i.e., facts, scientific findings, published and peer-reviewed scientific studies, etc.  NOT on what Crocodile Dundee thinks.

Hopefully, the representative of Media Watch had bothered to read my lengthy coverage on December 19.

Well we read it.  See Jez’s coverage of it here.

If so, she would know that in addition to quoting Professor Ridd,

Don’t know what “she” he is referring to here…

the coverage in news and the Inquirer section set out at considerable length how water temperature increases do pose an acknowledged threat to the reef. The piece, however, detailed how the Keppel reefs had bounced back in a much more robust way than was generally expected after bleaching in 2006.

Somewhat fair point, but again, see Jez’s point about that study, on which he was a coauthor here.

Further, we took the time to go out on to those reefs off central Queensland with Dr Ray Berkelmans of AIMS, who is highly regarded for the work he has done on these systems, dating back to the 1980s.

True.  Ray Berkelmans is a great scientist.

He had absolutely no problem with what I reported – I know that, because I checked back with him.

In summary, No one is suggesting that the potential threat to the reef should be underestimated.

Really?  Because, that is precisely the message I got from Jamie’s two stories on the GBR and climate change.

However, it is quite in order to question some of the more breathless forecasts about its imminent demise.

If Media Watch wants to review my work – that is fine and entirely appropriate; the Climate Change debate will be all the better for it. To premise its questioning on one self-interested view, however, is quite unreasoanble. I stand by my reporting.

Of course you do.

Best wishes,

Jamie Walker Queensland Bureau Chief The Australian

Spinning the science: Media Watch reports on the The Australian’s misunderstanding of coral science

http://vimeo.com/moogaloop.swf?clip_id=9308641&server=vimeo.com&show_title=1&show_byline=1&show_portrait=0&color=00ADEF&fullscreen=1

It seems that we were not the only ones to be alarmed by the serious errors on the front page of The Australian last week.  ABC Media Watch explores journalist Jamie Walker’s illogical and fact-free rampage, identifying severe shortcomings in his story and any support for the conclusion that, “Report undercuts PM’s reef wipeout”.

As we blogged last week, there was no such report or conclusion by AIMS scientists.  In a continuation of The Australian’s war on science, it appears that the truth again has been the first casualty.

Media Watch does an excellent job of checking sources and exposing the poor reporting by the Australian.  And the conclusion is pretty clear.  In the words of AIMS Director Dr Ian Poiner,

“Based on… rigorous peer-reviewed research, AIMS has found that the science is pointing to potentially severe consequences for the Great Barrier Reef from climate change. Current observations of the state of the Reef this year do not contradict this.”

Media Watch seem to hit the nail squarely on the head:

Yes Jamie, but your views – which aren’t shared by the scientists you’re quoting – don’t belong in a news story.

The Australian’s opinion pages have openly favoured climate change sceptics for years. That’s the paper’s right.

But this sort of reporting – and it’s by no means the first example – entrenches scepticism, shall we say, about The Australian’s ability to separate its news coverage from its editorial views.

Christopher Monckton: yet another lie exposed

http://vimeo.com/moogaloop.swf?clip_id=9306194&server=vimeo.com&show_title=1&show_byline=1&show_portrait=0&color=00ADEF&fullscreen=1

As part of his $100,000 tour around our great brown land, Christopher Monckton has claimed a great knowledge about the Great Barrier Reef. In an interview with Jon Faine of ABC Radio 774, Monckton claimed that he had a chart which showed that the temperature on the Great Barrier Reef have not changed for 30 years. He even claimed that the Great Barrier Reef Marine Park Authority itself had made the measurements itself (a fact disputed by senior GBRMPA scientist David Wachenfeld).

Going with Australia’s leading experts at the Bureau of the Meteorology, nothing could be further from the truth.  Sea temperatures in the Coral Sea are marching ever upward (see our posting here).  Not even our self-proclaimed marine expert Andrew Bolt can refute this one (unless, of course, there is a massive conspiracy as he claims that involves every Australian scientist that knows anything about sea temperature! Yeh, right Andrew!).

ABC Media Watch also caught up with this fabrication as well. For some amusing and revealing moments see the video above for Monckton’s fabrications or read the transcript here.
