@JohanEmpa what is the difference between the SSPs?
@gubi
The whole world:
▫️ doing nothing to reduce CO2 emissions --> SSP5
▫️ reducing emissions to net-zero and then removing CO2 from the atmosphere --> SSP1
SSP5 = Unthinkably bad weather disasters. Lots of animals going extinct. Lots of humans dying.
SSP1 = A bit worse than now. Small weather disasters that humanity can deal with.
@JohanEmpa right now, clearly our path will take us to closer to 5ºC rise. We will reduce from that but by how much, is the question. Best hope without a significant change in society and politics is 2.5ºC. Let’s see what actual policies are forthcoming at COP26. I believe it would be physically possible to stay under 1.5ºC but not within a profit driven society.
