Sea level

Parts of Sweden and Finland are bucking the trend of global sea-level rise. Since the ice that covered them during the last Ice Age melted, their land is bouncing back up and growing larger.

Antarctica has long been considered a last redoubt of cold in a warming globe. But new science suggests that a key part is warming up fast. Sam Eaton reports the finding could cause scientists to rethink their sea level projections for later this century.

Climate scientists say that as the world is warming up, polar ice is melting a lot faster than expected. And many of the world’s coastal regions are at grave risk.

The World’s Daniel Grossman reports from Greenland on disturbing changes. A new report says ice in Greenland and other northern regions is melting far faster than predicted just a few years ago, with possibly serious consequences for global sea levels.
