Remember:
1. Arctic sea ice gone by 2025
2. Antarctic ice collapse starts 2026
3. Coral reefs dead by 2027
4. Rainforests dying by 2028
5. 4 billion people lack water: 2029
6. Megacities uninhabitable by 2039
7. Most species extinct by 2049
This couldn't be true.
Could it?

“The chance that there will be any permanent ice left in the Arctic after 2022 is essentially zero,” Anderson said, with 75-80% of permanent ice having melted already in the last 35 years
“Can we lose 75-80% of permanent ice and recover? The answer is no"forbes.com/sites/jeffmcma…

Rapid deglaciation of West Antarctica beginning this decade is quite possible.

🔥 Most tropical corals die at 1.5°C (70-90%).
We hit 1.5C in the 2020s:
🔥 2°C of global warming (2029 - 2039) means the destruction of 99% of the world’s tropical reefs. interactive.carbonbrief.org/can-great-barr…
Even stopping emissions immediately wouldn't save them.

In 2017, scientists showed that unstoppable collapse of world tropical rainforests due to fragmentation was maybe just several years away, even with relatively minor deforestation.
Scientists now say that fragmentation is *increasing*.
Already too late?

Water:
Four billion living in regions of high water stress by 2030 says the UN, and that doesn't take into account abrupt warming from feedbacks.
600 million people in India alone will have no access to drinking water by 2030 according to a recent report.

Megacities are threatened by rapid sea level rise, unprecedented heat waves, and water & food insecurity.
In theory we could hit 3.5C by mid-century. There is peer-reviewed science suggesting this.
How many species could survive such rapid warming?
