COPENHAGEN. Dec 9, 2009. Extinction of Coral reefs and 10-20% of marine species is likely if greenhouse gases aren’t brought down to 350ppm, warned Professor Ove Hoegh-Guldberg from the University of Queensland. He gave a presentation at the US Pavilion at the COP15 climate negotiations in Copenhagen about the threat of climate change to the … Continue reading CO2 @ COP15: “Coral reefs don’t do well above about 350ppm”
In another of their “great” contributions, CO2 science has decided to take issue with a recent publication by Charlie Veron on the critical importance of 350ppm for the survivals coral reef (see here for our writeup at Climate Shifts). The issue seems to focus upon a series of unambiguous statements as to where we stand … Continue reading Pseudo “CO2 Science”
These two graphics from the Climate Interactive website are probably the clearest and most easy to understand images i’ve seen yet detailing the fallout from COP15. The ‘potential’ proposals (highlighted in green) are alot more promising than the official confirmed proposals. Some of these seem incredibly ambitious, such as Costa Rica proposing 0% emissions by 2021 (although Costa Rica is 99% clean energy already).
The results aren’t pretty – under the current confirmed proposals, in 2100 we would see CO2 levels peak at 780ppm – far above the recommended 350ppm for the worlds coral reefs. Even the low emissions pathway would see the world at 470ppm by the end of the century, and the ‘business as usual scenario’ is incredibly concerning. Continue reading The aftermath of Copenhagen – where are we headed?
UQ News, 8th November 2009 Australian marine scientists have issued an urgent call for massive and rapid worldwide cuts in carbon emissions, deep enough to prevent atmospheric CO2 levels rising to 450 parts per million (ppm). In the lead up to United Nations Copenhagen Climate Change Conference Professors Charlie Veron (former Chief Scientist, Australian Institute … Continue reading Scientists call for urgent ‘global cooling’ to save coral reefs
