Unstoppable Sea Level Rise ‘Locking In’ at 1 Foot a Decade

Unstoppable Sea Level Rise ‘Locking In’ at 1 Foot a Decade, Threatening Cities reports Ben Strauss at Climate Central. Global average sea level is currently rising by about 1 inch per decade. But our long-term sea level rise commitment or “lock-in” — the sea level rise we don’t see now, but which carbon emissions and warming have locked in for later years — is growing 10 times faster, and accelerating. An international team of scientists  recently published a study that found for every degree Fahrenheit of global warming due to carbon pollution, global average sea level will rise by about 4.2 feet in the long run. With the current rate of carbon emissions, this translates to a long-term sea level rise commitment that is now growing at about 1 foot per decade. We have two sea levels: the sea level of today, and the far higher sea level that is already being locked in for some not-too-distant tomorrow. We’ve almost locked in a 4-foot rise by 2100 that will flood cities, but by then we are guaranteeing our descendents an unstoppable further future 9 foot rise, if dramatic action isn’t taken.

 

Join the swelling numbers of voters TELLING Congress they’ll vote for Clean Energy candidates here: http://signon.org/sign/we-are-the-clean-99?source=c.em.cp&r_by=487176 . This is an ongoing campaign (the next Congressional election is in 2 years!) so please, spread the word. It’s our way of telling Congress that a strong clean energy voting bloc is out there. This is how YOU can make a difference.
