The fate of the planet’s coastlines depends on how fast Antarctica’s ice sheets melt. We don’t know what’s coming

Some regions of the continent have enough ice to push up sea levels by 15 metres if they all melt, but researchers don’t yet fully understand the consequences

On one side of Dr Ben Galton-Fenzi’s view across the vast Totten ice shelf, the sun sat low on the Antarctic horizon. On the other, a full moon.

The ice shelf is “flat and white”, says Galton-Fenzi. “If there’s cloud around, you lose the horizon.”

Rare twins born in DRC raise cautious hope for endangered mountain gorillas

Virunga park ranger says babies are well cared for by mother Mafuko but high infant mortality makes first weeks critical
