Last Sunday the Intergovernmental Panel on Climate Change (IPCC) warned that if the world does not curtail the amount of atmospheric carbon, there will be “severe, pervasive and irreversible impacts for people and ecosystems”. The 116-page IPCC report, a review of more than 30,000 climate-science studies, is the latest in a series that began in 1990. It has been signed off on by more than 100 governments, and is the first report to be released since 2007. It presents new conclusions that environmental scientists arrived over the past seven years.
The new conclusions? Mainly that unless we take our carbon emissions down to zero by 2100, we’re screwed. We can kiss homo sapiens (and a huge number of other species), “good bye”.
