The smartest scientists on the face of the planet, the ones studying climatechange and global warming, are mad as hell and they’re not going to take it any more. But the scientists now know that we’re NOT going to save our children from that hell and high water that’s coming their way.
The conference, attended by 130 international scientists and policy specialists, is the first to consider the global consequences of climatechange beyond 2 degrees Celsius (3.6 °F). 4 degrees of warming averaged over the globe translates into even greater warming in many regions, along with major changes in rainfall.

Verification of the emission reduction or carbon sequestration is critical in efforts to mitigate climatechange. One question is who will be responsible for verifying changes in carbon, which raises questions about the role of a regulatory agency for accrediting claimed changes in carbon levels from an activity.
