A leaked draft of the Intergovernmental Panel on Climate Change‘s next big climate report finds near unanimous certainty that greenhouse gas emissions from humans are primarily responsible for global warming. While their finding should surprise absolutely nobody, the 95 percent figure is, in fact, five percent higher than the one reached in the IPCC’s 2007 report. The United Nations panel also concludes that if emissions continue unabated, sea levels could rise by more than three feet by the end of the century, threatening major cities such as New York, Miami, London, Shanghai and Sidney.
The level of carbon dioxide — the greenhouse gas most responsible for climate change — is up 41 percent since the Industrial Revolution. The New York Times quotes the draft document as stating that “it is extremely likely that human influence on climate caused more than half of the observed increase in global average surface temperature from 1951 to 2010. There is high confidence that this has warmed the ocean, melted snow and ice, raised global mean sea level and changed some climate extremes in the second half of the 20th century.”
The report will become finalized in private meetings between scientists and government officials in Stockholm, Sweden in late September.
