Shade cloth ‘could protect reef from global warming’
Ove seems to be competing with Jimmy for the title of most spectacular involuntary trolley dismount – and he cost me $100 because I wagered this was a spoof piece or inadvertently released April Fools plan. Incredibly, this is about a real paper published today by Nature Climate Change and includes the floating shade cloth pitch, along with plans to electrocute the reef, inter alia. Continue reading
Improving water quality can help save coral reefs
Research from the University of Southampton and the National Oceanography Centre, Southampton has found that an imbalance of nutrients in reef waters can increase the bleaching susceptibility of reef corals. Continue reading

Caribbean Corals: What’s Really Been Giving Them A Hard Time?
In introducing their newest study of the subject, Cramer et al. (2012) write that “Caribbean reef corals did not appear to be affected by human activities until the 1980s (Hughes, 1994),” but they say that “since this period, coral cover in the Caribbean has declined by an average of 80% (Gardner et al., 2003) and branching species of Acropora and Porites corals have been replaced by non-branching species of Agaricia and Porites,” citing Aronson et al. (2004, 2005) and Green et al. (2008). Continue reading

Recurrent Bleaching and Storms Need Not Spell “the End” for Earth’s Corals
Adjeroud et al. (2009) write that “coral reefs are increasingly threatened by various disturbances, and a critical challenge is to determine their ability for resistance and resilience,” noting that “most models predict an increase in the frequency and severity of disturbances over the next few decades.” It is possible, of course, that those predictions may never come to pass; nevertheless, it is important to consider the natural ability of Earth’s corals to resist or recover from such challenges. Continue reading

Rapid transgenerational acclimation of a tropical reef fish to climate change
In the words of Donelson et al. (2012), “ocean temperatures are expected to become adverse for many marine species within the next 50-100 years because of global warming,” and they say that “tropical species are expected to have less capacity for thermal acclimation than temperate species because they have evolved in a more stable thermal environment.” But is this really true? Continue reading
Resistance to thermal stress in corals without changes in symbiont composition
Writing as background for their study, Bellantuono et al. (2012) say that “coral reefs are among the most biologically diverse and economically important ecosystems on the planet, providing ecological services that are vital to human society and industries through fisheries, coastal protection, pharmaceutical compounds and tourism,” but they say that “if the thermal sensitivity of corals does not change, coral reefs face serious problems in scenarios where tropical seas may be as much as 2°C-4°C warmer by the end of this century.” Continue reading
Adaptive evolution of a key phytoplankton species to ocean acidification
In an important paper published in the May 2012 issue of Nature Geoscience, Lohbeck et al. (2012) write that “our present understanding of the sensitivity of marine life to ocean acidification is based primarily on short-term experiments,” which often depict negative effects. Continue reading

Roger Bradbury: A World Without Coral Reefs
Woe! Gnash! Hand-wring! BS! [whoops did I type that out loud?] “IT’S past time to tell the truth about the state of the world’s coral reefs, the nurseries of tropical coastal fish stocks. They have become zombie ecosystems, neither dead nor truly alive in any functional sense, and on a trajectory to collapse within a human generation. There will be remnants here and there, but the global coral reef ecosystem — with its storehouse of biodiversity and fisheries supporting millions of the world’s poor — will cease to be.” Continue reading

Might have to take another one out of the “climate change causes” list: Viruses linked to algae that control coral health
Scientists have discovered two viruses that appear to infect the single-celled microalgae that reside in corals and are important for coral growth and health, and they say the viruses could play a role in the serious decline of coral ecosystems around the world. Continue reading

Failing the Acid Test – Jane Lubchenco
In the whole panoply of distortion and disinformation surrounding the claims of global warming, few can be more dishonest than the claims of Ocean Acidification. Head of NOAA, Jane Lubchenco, is currently on the Australian circuit to try and convince people that the new Carbon tax is valid and necessary to save the planet and of course, as it’s Australia, to save the Great Barrier Reef from extinction. Ocean acidification first saw the light of day in 2003 and found its way into AR4. It is now embedded in AR5, based on the shakiest of science.
Read on, to find out how the claim of a “30% increase in ocean acidity since the industrial revolution” came into being and check out the NOAA video, where Jane Lubchenco tries to fool the public with “The Vinegar Trick” and a piece of chalk.

Waaaaiiitaminute! Climate change suspended reef growth for 2 millennia
“The paper shows how natural climatic shifts stopped reef growth in the eastern Pacific for 2,500 years. The reef shutdown, which began 4,000 years ago…“
What were CO2 levels supposed to be then in definite pre-industrial times? The IPCC says 278 ppmv, right? I’ve seen a lot of coral in the GBR and it is thriving with levels nearing 400 ppmv. Corals didn’t fare so well in the ice age with levels down around the 200 ppmv mark. Corals evolved in the Ordovician with CO2 in the multiple thousand parts per million.
I’m seeing a pattern here – low CO2 bad, higher CO2, good. Continue reading
