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 … Continue reading →

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 →
