|The politicians love to think that staying below at 2°C rise in average global temperatures over the years 1800-present will somehow “save the planet.” If you believe that, you have yet to realize politicians lie with the regularity of sunrise.
Two degrees became the default goal almost by happenstance. The number originated with Yale economist William Nordhaus, who back in the 1970s published a paper suggesting that a rise in global temperature of more than 2 degrees would represent temperatures hardly seen over the past several hundred thousand years. Nordhaus’s number was based on preliminary intuition, though climate data has confirmed that during the past 100,000 years, global mean temperatures have rarely, if ever, reached much higher than 2 C above those around 1800.
