Scientists can now say with extreme confidence that human activity is the dominant cause of the global warming observed since the 1950s, a new report by an international scientific group said Friday.
Calling man-made warming “extremely likely,” the Intergovernmental Panel on Climate Change used the strongest words yet on the issue as it adopted its assessment on the state of the climate system.
In its previous assessment, in 2007, the U.N.-sponsored panel said it was “very likely” that global warming was man-made.
One of the most controversial subjects in the report was how to deal with a purported slowdown in warming in the past 15 years. Climate skeptics say this “hiatus” casts doubt on the scientific consensus on climate change. (Photo: JONATHAN NACKSTRAND / AFP)
