Arctic Sea Ice:
1. 3.48 million km² gone in just 40 years.
2. Climate models show the Arctic will be ice free in the summer between 2023 and 2067, likely by 2034.
3. A number of scientists note that satellite observations left out of models suggest 2024-2033 looks more likely.

2. 'Time horizons for summer sea ice loss of these three approaches turn out to be roughly 2020, 2030, and 2040'.

3. In the vast majority of the available CMIP6 simulations, the Arctic Ocean becomes practically sea‐ice free (area < 1 million km2) in September for the first time before 2050 in each of the 4 emission scenarios SSP1‐1.9, SSP1‐2.6, SSP2‐4.5 and SSP5‐8.5.agupubs.onlinelibrary.wiley.com/doi/abs/10.102…
4. 'Projections have varied from as early as 2026 to as distant as 2132. Now, according to research published in the journal Nature Climate Change, the Arctic could be "functionally ice-free" by September 2044 — and no later than 2067'.

5. Economists & bankers:
Almost no summer sea ice by 2040, decades sooner than expected.
60% chance of an effectively ice-free summer Arctic in the 2030s.
"for the rest of the century and onward, it’s hard to think of anything more globally important".
