UN Leak Shows More Evidence Humans Cause Global Warming

A leaked draft of the UN’s most comprehensive study ever on climate change shows increasing evidence that links human activity to global warming. It is “extremely likely” mankind is responsible for more than half of the observed temperature rises since the 1950s, a United Nations agency said in a draft report. In the UN’s last study, in 2007, human influence on the temperature rise was deemed “very likely.”

The report by the UN Intergovernmental Panel on Climate Change is due for publication starting in September. It will come in three parts and then a final summary, culminating in October 2014. It’s intended to guide envoys from 194 countries working on adopting a new treaty by 2015 that would fight climate change.
