Kate Marvel, a climatologist at GISS and the paper’s lead author, said the results showed the "complexity" of estimating future global temperatures.
The study found existing models for climate change had been too simplistic and did not account for these factors.
"This means that Earth's climate sensitivity to carbon dioxide—or atmospheric carbon dioxide’s capacity to affect temperature change—has been underestimated, according to the study."
The Intergovernmental Panel on Climate Change, which draws its TCR estimate from earlier research, places the future estimate rise at 1.8°F (1.0°C).
But the new NASA study dovetails with a GISS study published last year that puts the TCR value at 3.0°F (1.7° C).
Mr Schmidt said: “If you’ve got a systematic underestimate of what the greenhouse gas-driven change would be, then you’re systematically underestimating what’s going to happen in the future when greenhouse gases are by far the dominant climate driver.”

James Hansen's legacy lives on at GISS, continuing to embarrass all of NASA's legitimate scientists.
If it wasn't so sad, it would be hilarious.
