Global Warming Accelerating Towards a Climate Punch – Study

A new study of ocean warming shows that global warming has accelerated over the past 15 years, reports Dana Nuccitelli at Climate Progress, resulting in the dramatic warming of the oceans, as  90% of this  increasing heat is absorbed by them, nearly a third of it in the deeper layers, 700 meters or deeper.  Some recent studies have concluded based on the slowed global surface warming over the past decade that the sensitivity of the climate to the increased greenhouse effect is somewhat lower than the IPCC best estimate. Those studies are fundamentally flawed because they do not account for the warming of the deep oceans. Meanwhile, the slowed surface air warming over the past decade has lulled many people into a false and unwarranted sense of security, because the climate doesn’t seem to be changing very fast. But top British climatologist Kevin Trenberth notes that as the heat spreads deeper in the oceans, it may temporarily slow surface heating, but, he says, “at the expense of a greater, earlier, long-term warming, and faster sea level rise.” The warning is clear, folks: a greater climate punch looms ahead.

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.
