text:  It is widely accepted that humans have been heating up the planet for over a century by burning coal, oil, and gas. It is widely accepted by dumb people, but I digress. Earth has already warmed by almost 1.2 degrees Celsius. That is 2.2 degrees Fahrenheit since pre-industrial times. Not true. And the planet is poised to race past the hoped-for limit of 1.5 degrees Celsius of warming. Also false.
