A subida do nível do mar será de 1,3 m em 2100, se não houver surpresas desagradáveis, digo eu, nomeadamente, do lado da Gronelândia e da Antártica Ocidental.
"Sea levels will rise by a much 4.3 feet (1.3 m) by 2100 if humans
continue to emit at current rates. That figure could be reduced to as
low as 0.8 feet (0.24 m) if humans peak and then reduce carbon emissions
in the coming decades.
Achieving such reductions won’t be an easy feat. Countries from around the world agreed in Paris last December to try to keep average global temperatures from rising more than 3.6°F (2°C) by 2100. Even if that goal is achieved—some are rightfully skeptical—sea levels are still expected to rise far beyond 0.8 ft (0.24 m). That could erase low-lying island countries like Kiribati and affect coastal cities on the Atlantic coast of the United States."
