Sea level rise from ocean warming underestimated, scientists say

Thermal expansion of the oceans as they warm is likely to be twice as large as previously thought, according to German researchers

The amount of sea level rise that comes from the oceans warming and expanding has been underestimated, and could be about twice as much as previously calculated, German researchers have said.

The findings in the Proceedings of the National Academy of Sciences, a peer-reviewed US journal, suggest that increasingly severe storm surges could be anticipated as a result.
