Reply to Ridd et al.’s Technical Comment to Science: “Have coral calcification rates slowed in the last twenty years?”

Several denialists have sort to deliberately confuse the readership over the important evidence gathered by De’ath et al. (2009) on slowing coral calcification on the Great Barrier Reef.  Given the recent resurgence in this misinformation, I thought it would be a good idea to post Dr Glenn De’ath, Dr Janice M. Lough and Dr Katharina … Continue reading Reply to Ridd et al.’s Technical Comment to Science: “Have coral calcification rates slowed in the last twenty years?”

Peter Ridd is not the only reef expert at James Cook University

Although you’d think so given how frequently he is quoted in the Australian media, almost exclusivly in stories arguing that the GBR is in “bloody brilliant shape” and that climate change, sediment pollution, and ocean acidification are not threats to the reef’s future. For example, in Jamie Walker’s piece last December on “How the reef … Continue reading Peter Ridd is not the only reef expert at James Cook University

More disinformation from Dr Peter Ridd in response to the ocean thermostat study

I see over on “The Politics and Environment Blog” in response to the ocean thermostat study published recently that the following comment from the ill-informed Dr Peter Ridd’s diatribe “The Great Great Barrier Reef Swindle” is again being misconstrued as evidence that warmer waters will be beneficial for corals: “The scientific evidence about the effect … Continue reading More disinformation from Dr Peter Ridd in response to the ocean thermostat study

Ove Hoegh-Guldberg and Peter Ridd on Triple J Radio

I was interviewed recently on Triple J radio (an Australian nation-wide radio station) for a current affairs program called “Hack” along with Peter Ridd to discuss the “Great Barrier Reef Swindle” (as I have blogged here before). [audio:http://www.climateshifts.org/climateshifts/audio/ovehgtriplej.mp3%5D Please feel free to leave your comments below – download the entire Hack episode at Triple J, … Continue reading Ove Hoegh-Guldberg and Peter Ridd on Triple J Radio

The “GBR Swindle” revisited – response to Peter Ridd

It seems that “The Great Barrier Reef Swindle” and my subsequent response generated a fair amount of debate throughout the blog world and the scientific community. Dr Ridd has posted his response to the my comments regarding the science behind the response here, and in keeping with the science and debate, see my response below.

Before I go into detail on this, attached is one of the paired photographs from the inshore reefs in Bowen, Queensland detailing local scale changes on the Great Barrier Reef during the 20th century (photographs speak louder than words):

Expert credibility in climate change: not all climate research and expertise are equal.

A fairly convoluted (but interesting none the less) paper just got published in PNAS by Anderegg et al (2010) looking at climate change and scientific credibility (more coverage by the Guardian here). Why don’t we trust climate scientists? To answer this question, the authors conducted a literature search of 1,372 climate researchers whose work “constitutes … Continue reading Expert credibility in climate change: not all climate research and expertise are equal.

The art of denial

I was sent this insightful article by ANU academic Andrew Glikson about denialism written by two medical scientists, Pascal Diethelm and Martin McKee. Whether it is the belief that the world is only a few thousands of years old, that HIV does not cause AIDS, or greenhouse gases don’t affect the energy balance of the … Continue reading The art of denial

Science behind Great Barrier Reef water quality management

Articles from Peter Ridd of James Cook University in newspapers and on blog sites and letters to the editor supporting his position (e.g. Tom Darlington, 9 February 2010 in the Townsville Bulletin) claim there is no scientific evidence agricultural pollution is damaging the Great  Barrier Reef. As well, claims are made that there is a … Continue reading Science behind Great Barrier Reef water quality management
