Some other scientists, however, have cast doubt on the paper’s conclusions that climate change is accelerating faster than models predict.
Hansen, a director at the Earth Institute at Columbia University, is a renowned climate scientist whose 1988 testimony to the US Senate first brought global attention to climate change.
US scientist James Hansen, pictured in 2013, is credited as the first to publicly raise the alarm about climate change in the 1980s.
But while science is clear that the rate of global warming is increasing, the idea that it is accelerating beyond what models predict is controversial.
The findings “are very much out of the mainstream,” said Michael Mann, a leading climate scientist at the University of Pennsylvania.
