PARIS, Feb. 2 (UPI) -- Human activity is the source of global warming, said a major scientific report on greenhouse gas emissions issued by a United Nations panel in Paris Friday.
The report from the Intergovernmental Panel on Climate Change, which released its report at a Friday morning press conference Webcast around the world, also said global warming could not be reversed.
The rising sea levels and higher temperatures that accompany global warming "would continue for centuries ... even if greenhouse gas concentrations were to be stabilized," the panel's report said.
Friday "will perhaps one day be remembered as the day when the question mark was removed from the question of whether human activity has anything to do with climate change on this planet," said Achim Steiner, executive director of the United Nations Environmental Program, the Chicago Tribune reported. "Those who have doubts can no longer now ignore the evidence."
Lead researcher Susan Solomon, a U.S. government scientist, said the report was based on data, not politics.
