Twenty years ago, governments agreed to limit the global temperature rise to less than 2 degrees. Don't be fooled by the talks in climate change. The world is on track to become FOUR degrees warmer.
At two degrees warmer, Marine life are at risk!
4 Degrees warmer, great cities will be washed away. What is the price to relocate the bulk of humanity from immersing cities?
5 degrees warmer, civilization collapses. Asking about the cost of survival in such a world is meaningless when civilization is no longer viable.
6 degrees warmer, there will be mass extinction. Nature will recover in a few million years. There will be no grandchildren's grandchildren. How do we face our grandchildren?
