An international team of climate scientists says it is 95 to 100 percent confident that human activity -- largely from burning fossil fuels -- is the main cause of global warming since the 1950s, according to a leaked draft of the upcoming report from the Intergovernmental Panel on Climate Change.
The report, the first by the IPCC in six years and set to be released in September, also says that global sea levels could rise more than 3 feet by the end of this century if no action is taken to curb the worldwide emissions of greenhouse gases before then.
The panel found it "extremely likely" that humans were responsible for "more than half of the observed increase in global average surface temperature from 1951 to 2010," the draft report says, according to the New York Times.
