The Arctic:

1. 95% of old ice gone
2. ice free by 2021-2031
3. fastest warming place on Earth
4. no evidence sea ice will recover
5. melting is destabilising the planet
6. the oldest and thickest Arctic sea ice is disappearing twice as fast as ice in the rest of the Arctic Ocean

7. heatwaves 20°C more than usual
8. vast wildfires mean carbon bursts
9. permafrost collapse is irreversible
10. the last time the Arctic was ice-free in the summer, modern humans didn’t exist

'Climate models predict Arctic summers will soon be ice-free - perhaps as early as 2030'

But things are worse than that..

Arctic sea ice is melting more rapidly than models can explain - an ice-free summer is likely to occur in the 2020s.

Crop failures:

As the Arctic warms rapidly, the polar jet stream is shifting from its usual patterns, resulting in more extreme weather events, from heat waves and droughts that cause crop failures to torrential downpours that can flood major cities.
