Fact-Checking the Global Warming Deniers
Beware of these oft-repeated talking points. None of them are true
By JEFF GOODELL
1. There’s more ice in Antarctica than ever.
The past few years have seen an expansion of Antarctica’s coastal ice sheets – a byproduct, ironically, of climate change, which has brought increased snow and rainfall to the continent. Meanwhile, Antarctica’s inland ice sheets are melting at an alarming rate – 1,350 billion tons of ice disappeared into the ocean between 1992 and 2011. And that rate is increasing, fueling global rises in sea level.
Increased snow and rain is causing sea ice to spread? What kind of moron would think up such idiocy? Sea ice is formed when cold air over the water extracts enough heat to cause the seawater to freeze. Antarctic sea ice has spread because air temperatures have been getting colder.
And it takes a double moron to believe that Antarctica is below freezing at warmer lower latitudes and altitudes (edge of the sea ice) while melting in the colder interior at higher latitudes and altitudes. Not to mention the fact that sea ice freezes at a lower temperature than glacial ice.
The rumors about Antarctica losing mass are from some fatally flawed gravity studies from the University of Texas a few years ago, done by people who were too stupid to know that glacial rebound causes the bedrock below the glaciers to change elevation. Their legacy of junk science continues to grow and expand.
