UN Leak Shows More Evidence Humans Cause Global Warming
A leaked draft of the UNâ€™s most comprehensive study ever on climate change shows increasing evidence that links human activity to global warming. It is â€œextremely likelyâ€ 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 UNâ€™s last study, in 2007, human influence on the temperature rise was deemed â€œvery likely.â€
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. Itâ€™s intended to guide envoys from 194 countries working on adopting a new treaty by 2015 that would fight climate change.
