Trump administration sees a 7-degree rise in global temperatures by 2100

The trump people are telling us that we are going to be totally fucked by the consequences of climate change and global warming, so we might as well keep on burning gasoline in our vehicles without further limitations because the additional carbon spewed into the atmosphere won’t make any difference. That is the sad policy of the trump administration: have fun now, while you can, and let the oil companies make tons of money, because your little car that runs on electricity or sips gasoline won’t make any difference. Make no mistake about how pervasive this attitude is: the republicans are solidly behind this “fiddle while Rome burns” attitude and approach.

Excerpt:

Last month, deep in a 500-page environmental impact statement, the Trump administration made a startling assumption: On its current course, the planet will warm a disastrous 7 degrees by the end of this century.

A rise of 7 degrees Fahrenheit, or about 4 degrees Celsius, compared with preindustrial levels would be catastrophic, according to scientists. Many coral reefs would dissolve in increasingly acidic oceans. Parts of Manhattan and Miami would be underwater without costly coastal defenses. Extreme heat waves would routinely smother large parts of the globe.

But the administration did not offer this dire forecast, premised on the idea that the world will fail to cut its greenhouse gas emissions, as part of an argument to combat climate change. Just the opposite: The analysis assumes the planet’s fate is already sealed.

The draft statement, issued by the National Highway Traffic Safety Administration (NHTSA), was written to justify President Trump’s decision to freeze federal fuel efficiency standards for cars and light trucks built after 2020. While the proposal would increase greenhouse gas emissions, the impact statement says, that policy would add just a very small drop to a very big, hot bucket.

“The amazing thing they’re saying is human activities are going to lead to this rise of carbon dioxide that is disastrous for the environment and society. And then they’re saying they’re not going to do anything about it,” said Michael MacCracken, who served as a senior scientist at the U.S. Global Change Research Program from 1993 to 2002.

The world would have to make deep cuts in carbon emissions to avoid this drastic warming, the analysis states. And that “would require substantial increases in technology innovation and adoption compared to today’s levels and would require the economy and the vehicle fleet to move away from the use of fossil fuels, which is not currently technologically feasible or economically feasible.”

David Pettit, a senior attorney at the Natural Resources Defense Council who testified against Trump’s freeze of car mileage standard Monday in Fresno, Calif., said his organization is prepared to use the administration’s own numbers to challenge their regulatory rollbacks. He noted that NHTSA document projects that if the world takes no action to curb emissions, current atmospheric concentrations of carbon dioxide would rise from 410 parts per million to 789 ppm by 2100.
