Greenland:

1. Recent melt is exceptional
2. Models underestimate rate
3. Loss of ice ¼ trillion tons per year
4. Sea level rise feedback cycle
5. Melt accelerating exponentially
6. Disrupting ocean conveyor belt
7. Ice sheet changes are non-linear
8. Now beyond the tipping point

Giant slabs of ice have been thickening and spreading under the Greenland snow preventing surface meltwater from trickling down and being absorbed. Instead, more water pours off the surface of the ice sheet and into the ocean, speeding up sea level rise. https://insideclimatenews.org/news/18092019/greenland-ice-sheet-melting-sea-level-rise-climate-change-heat-wave-study">https://insideclimatenews.org/news/1809...

Greenland’s recent melt is “exceptional” over the past 350 years and the ice sheet’s response to higher temperatures is now “nonlinear.” https://e360.yale.edu/features/in-greenlands-melting-ice-a-warning-on-hard-climate-choices">https://e360.yale.edu/features/...
