![]() Monitoring data collected annually from fixed sites at 47 reefs across 1300 km of the GBR indicate that overall regional coral cover was stable (averaging 29% and ranging from 23% to 33% cover across years) with no net decline between 19. Most obvious among changes to reefs is loss of hard coral cover, but a precise multi-scale estimate of coral cover dynamics for the Great Barrier Reef (GBR) is currently lacking. The reefs have been going to hell in a handbasket for years - according to the Greeniesĭisturbance and the Dynamics of Coral Cover on the Great Barrier Reef (1995–2009)Ĭoral reef ecosystems worldwide are under pressure from chronic and acute stressors that threaten their continued existence.

The idea is to examine individual events like a detective investigating a crime, searching for telltale fingerprints of climate change. The second line of evidence comes from a nascent branch of science called climate attribution. "Now we can make the statement that particular events would not have happened the same way without global warming," says Kevin Trenberth, head of climate analysis at the National Center for Atmospheric Research (NCAR) in Boulder, Colo. Northeast.Scientists used to say, cautiously, that extreme weather events were "consistent" with the predictions of climate change. ![]() In this year alone massive blizzards have struck the U.S. Storm Warnings: Extreme Weather Is a Product of Climate Change: Scientific American "Scientific" American claims that human "fingerprints" are showing up on individual weather events fails to tell us exactly what this means Much larger version of graphic here or a very sharp but slow-loading copy here Instead of rising faster, it has actually STOPPED its long-term rising tendency
