The most authoritative report on climate change is using the strongest wording ever on the source of global warming, saying it is "very likely" caused by humans and already is leading to killer heat waves and stronger hurricanes, delegates who have seen the report said Thursday.
Dozens of scientists and bureaucrats from 113 countries are editing the new report by the Intergovernmental Panel on Climate Change in closed-door meetings in Paris. Their report, which must be unanimously approved, is to be released Friday and is considered an authoritative document that could influence government and industrial policy worldwide.
Three participants said the group approved the term "very likely" in Thursday's sessions. That means they agree that there is a 90 percent chance that global warming is caused by humans.
"That is a big move. I hope it is a powerful statement," said Jan Pretel, head of the department of climate change at the Czech Hydrometeorological Institute.
"I hope that policymakers will be quite convinced by this message," said Riibeta Abeta, a delegate from the island nation Kiribati, which is worried about overrun by rising seas. "The purpose is to get them moving."
