- potential collapse of maritime currents that lead to relatively mild climates in Britain
- triggering of multiple irreversible climate tipping points (arctic ice sheet)
- more common and much more devastating extreme weather events (warmer air can carry more water)
- the aforementioned weather results in infrastructure damage and lack of food within big parts of the world. Waves of migration
- median sea level rise of more than a meter means extremes will be much higher, a big part of the human population lives next to the sea
And much more — this was the absolute minimum and we surpassed it faster than expected.
For example, consider ocean acidification.
Also consider the number of tipping points and positive feedback loops that exist. How close are we to those?
from open ai: The power required to raise the temperature of all the Earth's water by 1°C in one second would be 5.57 × 10¹⁸ megawatts.
