Cut The Soot, Too, To Slow Sea Level Rise – Study

Cutting so-called  “short-lived climate pollutants” in addition to the well known long lived ones, would greatly slow the rate of sea level rise, which is one of the biggest threats global warming poses, says a new study, reports Andrew Freedman at Climate Central. Short term pollutants, such as soot and methane gas, warm the climate on timescales of a few weeks to a decade, in contrast to long-lived greenhouse gases such as carbon dioxide (CO2). The study, published in Nature Climate Change, found that reducing emissions of these short-lived climate pollutants by 30 to 60 percent by 2050 would slow the annual rate of sea level rise by almost 20 percent by then. Combining this with decreasing CO2 emissions could cut the rate of sea level rise in half by 2100, from nearly an inch to under a half inch annually, while reducing the total sea level rise by about a third during the same period. Related research by Climate Central scientists shows that the emissions reductions would potentially benefit more than 2 million Americans by 2100, who might otherwise be living below sea level at that point.

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.

Cutting short-lived pollutants can slow sea level rise. A new study finds that it is possible to greatly slow the rate of sea level rise by cutting so-called “short-lived” climate pollutants, such as soot and methane, in combination with reductions in long-lived greenhouse gases such as carbon dioxide.
