Sea levels could rise by more than 3 feet by the end of the century, endangering some of the world’s largest cities including New York, London and Shanghai, according to a report from the Intergovernmental Panel on Climate Change, The New York Times reported.
The report concludes with more certainty than all similar reports released by the organization that the planet is warming and that humans are primarily to blame.
“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,” the draft report reads, according to The Times. “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.”
