The Green New Deal would not change the climate materially despite its hefty cost and dire consequences to jobs and citizens
...In other words, the Green New Deal is a fool's errand.
But here’s the key thing: Even if Americans were on board with this radical change in behavior and lifestyle, it wouldn’t change our climate.
In fact, the U.S. could cut its carbon dioxide emissions 100 percent and it would not make a difference in abating global warming.
Using the same climate sensitivity (the warming effect of a doubling of carbon dioxide emissions) as the U.N.’s Intergovernmental Panel on Climate Change assumes in its modeling, the world would be only 0.137 degree Celsius cooler by 2100. Even if we assumed every other industrialized country would be equally on board, this would merely avert warming by 0.278 degree Celsius by the turn of the century.
One of the biggest sources of carbon dioxide emissions is developing countries.
But while one of the priorities of the Green New Deal is to make the U.S. a lead exporter in green technologies, assuming developing countries will forgo cheap, abundant carbon dioxide-emitting energy for more expensive intermittent sources is pure fantasy.
