A new study in the journal Nature says most sea level rise research may have underestimated coastal water heights by an average of 1 foot or about 30 centimeters.

Greenland’s fishermen are struggling as warming weather from climate change makes the sea ice unreliable and the fish harder to predict.

A widely used method to calculate sea level rise may have missed up to a century of change, so the risks could hit home for millions sooner than thought.

Researchers found that a majority of studies on coastal sea levels underestimated how high water levels are, and hundreds of millions of people are closer to peril than previously thought.

Most coastal risk assessments have underestimated current sea levels, meaning tens of millions of people face losing their homes to rising waters earlier than expected ...
