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.

A new study says climate change added $8 billion to the massive costs of 2012's Superstorm Sandy.

So instead of 80 million people living in low-lying areas that would flood annually by 2050 as the world warms, this new study finds the population at risk is closer to 300 million people. Space-based radar says 170 million are at risk in that scenario. Five outside sea level rise experts said the study highlighted a problem with current data, especially in Asia.
