Climate change deniers have tried to dismiss the science, citing a 15-year slowdown in atmospheric warming. That was played down in the report, which called it a natural phenomenon that is masking the ongoing warming. The findings reiterate the Panel's 2007 assessment that the warming trend is "unequivocal," says Christiana Figueres, the top United Nations' climate officer.
"Everything that we thought we knew about climate change has been underestimated, that we will have much faster and much more intense effects from the growing concentrations of greenhouse gases in the atmosphere. So it's a very sobering message that calls for a more invigorated and more accelerated policy response to address that."
Figueres hopes the new IPCC report will compel policymakers to move global climate talks forward.
"That policy response will have to end up in a global agreement that is going to be legally based and applicable to all countries and will be adopted in the year 2015. And for that, governments are already working."
Government leaders and climate experts will get an opportunity to do that at the next round of climate negotiations in Warsaw, Poland in November. Friday's IPCC report will be followed next year by reports on the impact of climate change and what can be done about it. |
