New York Rep. Ocasio-Cortez’s “Green New Deal” won’t impact global warming, according to a climate model.
It would only avert 0.14 degrees Celsius of projected warming by 2100 — that’s not even measurable.
Variation - Amount - Scientist
“The year-to-year variation is very close to the total amount of warming that would be ‘saved’ by 2100,” one scientist said.
Democrats are increasingly lining up behind New York Congresswoman Alexandria Ocasio-Cortez’s call for a “Green New Deal,” but few, if any, have talked about its actual impact on global warming.
Green - New - Deal - Goals - Impact
Even if all the Green New Deal’s goals were achieved, it would have a negligible, and likely immeasurable, impact on projected global warming, according to climate model simulation provided by a libertarian think tank.
“I seriously think the effect would — at best — be barely detectable in the climate record,” Patrick Michaels, a climatologist with the Cato Institute, told The Daily Caller News Foundation.
Cato - Carbon - Tax - Temperature-Savings - Calculator
Cato developed its own “Carbon Tax Temperature-Savings Calculator” to estimate the amount of warming that might be averted through reducing greenhouse gas emissions, like carbon dioxide.
The carbon calculator is based on the so-called “MAGICC” climate model simulator, developed by the National Center for Atmospheric Research with funding from the Environmental Protection Agency.

“The year-to-year variation is very close to the total amount of warming that would be ‘saved’ by 2100, according to EPA’s own model,” Michaels said.
Climate - Sensitivity - Estimate - Degrees - Celsius
And that assumes a climate sensitivity estimate of 3 degrees Celsius. Climate sensitivity refers to the amount of warming that can be expected from a doubling of atmospheric greenhouse gas concentrations.
The United Nations estimates climate sensitivity is anywhere between 1.5 and 4.5 degrees Celsius, though an April 2018 study suggested that climate sensitivity is likely...
