The correct "12 years" claim: We have 10 yrs, 5 months, 4 days until we must cut global emissions in half for a 50/50 chance to stay under 1.5°C of mean global heating according to IPCC SR1.5

Many scientists, including me, feel this underestimates irreversible global change
But we'd be fortunate to go at even this too-slow rate considering our emissions are still exponentially increasing. This is why it's a #ClimateEmergency. All hands on deck!

(I couldn't find a more current plot; unfortunately emissions did not roll off in 2014 - far from it)
So do all you can:
1 talk every chance you get
2 vote on climate of course
3 join climate action group(s)
4 get educated on solutions
5 engage politically
6 protest & civil disobedience
7 burn less fossil fuel to shift culture
8 get creative
Some have misunderstood, so let me clarify: I don't intend to claim precision about anything except how much time there was between when I tweeted and 2030. The IPCC set 2030 as a *rough* yardstick for the conditions mentioned.

But the days are counting.
