Who knew that Obama would actually keep a promise?
According to a statement issued yesterday by the US National Science Foundation:
For an 18-month period beginning in 2010, the oceans mysteriously dropped by about seven millimeters.
This is pretty wacky, as warming ocean temperatures ought to mean that the oceans expand. Furthermore, there’s no disagreement about the fact that the world’s ice sheets and glaciers have been steadily melting for a long time – otherwise Europe would still be covered in ice. And there’s no reason they’d suddenly stop melting. So how could sea levels actually go down?
In short, it’s probably human-caused climate change that did it: specifically the Australian flooding of 2010 and 2011, which is generally thought by climate scientists to be at least partly attributable to rising atmospheric carbon levels caused by human fossil-fuel burning.
“It’s a beautiful illustration of how complicated our climate system is,” says John Fasullo of the US National Center for Atmospheric Research.
“The smallest continent in the world can affect sea level worldwide.”
Take a bow Barry.
