It sounds like something from a sci-fi movie, but the artificial manipulation of the Earth’s climate has been touted as a possible strategy to reduce the effects of unmitigated climate change. Thanks to the painfully slow progress that has been made towards reducing our carbon emissions, there has been some surprisingly serious discussion about the … Continue reading No quick fix for climate with geoengineering
Professor Steve Palumbi of Stanford University is pioneering the use of small ‘to the point’ videos (‘microdocs’) to illustrate important issues that face the ocean. In this one, he outlines (with superb clarity) the issue of ocean acidification and illustrates why it is such a serious threat to marine ecosystems like coral reefs. While Steve … Continue reading Microdocumentaries, Steve Palumbi and ocean acidification
A study published in Nature Reports Climate Change on 11 June 2009 reports on the consequences of the emission targets being set by countries, including the US and Australia, in the lead-up to the international climate negotiations in Copenhagen in December. Joeri Rogelj and colleagues conclude, “National targets give virtually no chance of constraining warming … Continue reading “National targets give virtually no chance of protecting coral reefs”
Seagrass meadows have long been known to be highly productive habitats, and as a result producing oodles of oxygen in the midday sun. Anyone who’s ever snorkelled over a seagrass meadow on a sunny day will have seen seagrass leaves furiously bubbling away. This photosynthetic productivity can result in an increase in the pH of … Continue reading Could coral reefs close to seagrass be buffered from ocean acidification?
‘Climate change is turning our seas acidic, academies warn’ – Reuters News, May 31st 2009 Climate change is turning the oceans more acid in a trend that could endanger everything from clams to coral and be irreversible for thousands of years, national science academies said on Monday. Seventy academies from around the world urged governments … Continue reading Ocean acidification an ‘underwater catastrophe’
More than 400 leading scientists from nearly two-dozen countries have signed a consensus statement on the major threats facing the Pacific Ocean. The threats identified as the most serious and pervasive include overfishing, pollution, habitat destruction and climate change. “This is first time the scientific community has come together in a single voice to express … Continue reading World Ocean Conference (Part II): Scientists urge world leaders to respond cooperatively to Pacific Ocean threats
“A Sea Change – Imagine a World Without Fish” is a recently released documentary film about ocean acidification, the little-known ugly sister of global warming. The film website http://www.aseachange.net explains it “… aims not only to educate viewers about the science of our rapidly-changing oceans, but also to engage them on accessible terms.” The full … Continue reading A world without fish – what would it take?
