IPCC: Limiting climate change to below 1.5°C would require "unprecedented transitions in all aspects of society."

(Less than 400 people worldwide are watching this lifestream right now.)

IPCC: The world has already warmed 1.0°C above pre-industrial levels.

On our current path, the world will reach 1.5°C warming in as little as 12 years.

IPCC: Limiting warming to less than 1.5°C would save 10 million people from sea level rise displacement vs. warming of 2°C and *several hundred million* people from climate-related extreme poverty.

***several hundred million*** people.
