On June 2, Tom Davis made the following statement regarding the Paris Climate Accord, which Donald Trump had pledged to withdraw the U.S. from the day before:
TOM DAVIS:"When the Massachusetts Institute of Technology, MIT for short, compiled the pledges and compared them with its own preexisting projection they found that the temperature reduction by the year 2100 was only 0.2 degrees Celsius. When the analysts compared the pledges with the projection created by the UN's Intergovernmental Panel on Climate Change back in 2000, they found, get this, no change at all."
Accuracy of Claim: Misleading
MIT issued a statement calling this talking point misleading after right wing news outlets began using it as a talking point in support of Trump's pledge to withdraw the U.S. from the Paris Climate Accord.
From MIT's statement:
"The researchers in MIT’s Joint Program on the Science and Policy of Global Change who led the relevant analysis find this statement to be misleading, for two reasons.
First, the 0.2 degree-figure used in the talking point reflects the incremental impact of the Paris Agreement compared with the earlier Copenhagen agreement. If you instead compare the impact of the Paris Agreement to no climate policy, then the temperature reduction is much larger, on the order of 1 degree Celsius — 1.8 degrees Fahrenheit — by 2100. This would be a significant reduction in the global temperature rise, though much more is needed if the world is to achieve its goal of limiting warming to 2 degrees Celsius or less.
Second, the analysis accounts only for countries’ pledges under the Paris Agreement, assuming no further strengthening of the commitments in years after 2030. The Paris Agreement is a milestone of the ongoing UN Framework Convention on Climate Change, which is committed to ongoing annual meetings to regularly revisit and ratchet up nations’ climate goals, making them more ambitious over time."
