Africa's share of global population is projected to grow from 17% in 2020 to 25% in 2050 and 38% by 2100, while the share of Asia will fall from 60% in 2020 to 55% in 2050 and 45% in 2100.

If there are very deep cuts in emissions, sea level rise would slow between 2050 and 2100. It could then reach by 2100 slightly over 30 cm (1 ft) from now and approximately 60 cm (2 ft) from the 19th century. With high emissions it would instead accelerate further, and could rise by 1.0 m (3 + 1 ⁄ 3 ft) or even 1.6 m (5 + 1 ⁄ 3 ft) by 2100.
A 2018 paper estimated that if global warming was limited to 2 °C (3.6 °F), gradual permafrost thaw would add around 0.09 °C (0.16 °F) to global temperatures by 2100, [116] while a 2022 review concluded that every 1 °C (1.8 °F) of global warming would cause 0.04 °C (0.072 °F) and 0.11 °C (0.20 °F) from abrupt thaw by the year 2100 and ...
