Global coastal sea levels are on average 1 foot higher than previously assumed, a new report finds, raising alarms the world ...

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.

Using a more accurate coastal height baseline means that a 3-foot rise in seas could inundate up to 37% more land and threaten 77 million to 132 million more people, researchers said.

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 ...

Climate change's rising seas may threaten tens of millions more people than scientists and government planners originally thought because of mistaken research assumptions on how high coastal waters ...
