We’ve heated the globe .8 degrees already. We can probably abide 2 degrees. Not 4. http://www.vox.com/2014/4/22/5551004/two-degrees …
Two degrees: How the world failed on climate change
For 20 years, climate policy has centered around one goal: making sure we don’t get more than 2°C of global warming. That goal is looking increasingly delusional.
@chrislhayes 2 degrees is “tipping point,” but 1.9 degrees would still cause major catastrophes, crop failures, etc.
