The Apocalypse is coming
According to the Global Tipping Points Report 2025: “Already warm-water coral reefs are crossing their thermal tipping point and experiencing unprecedented dieback…" This is sickening news, not just because so much beauty and biodiversity is being lost, but also the livelihoods of hundreds of millions of people who depend on coral reefs.
The world is likely to hit 2°C warming between 2034 and 2052. According to New Scientist (28 May), the world could experience a year above 2°C of warming as early as 2029. The chances are slim, but it’s only four years away.
What happens at 2°C? It would be the start of irreversible loss of the Greenland and Antarctic ice sheets leading eventually to a 12-20 metre sea-level rise. It would lead to further deoxygenation of the oceans, threatening all creatures that depend on oxygen to survive. The Atlantic Meridional Overturning Circulation would reduce in strength by at least 34% to 45% with severe implications for Western Europe. Arctic summer sea ice will be lost.
The Amazon would be moving to a state where it could not support rainforesta, with far-reaching effects on atmospheric moisture circulation patterns.
We cannot go to 2°C. It’s simply too dangerous.
