Ice Ice Baby
Scientists receiving new information about “squishy ice” in Antarctica:
Knowing how the massive ice sheets atop Antarctica and Greenland work is key to predicting how global warming could raise sea levels and flood coastal cities. But a new study upends what scientists thought they knew. It turns out it’s not just ancient snow that makes up the ice sheets, but water deep under the sheets also thaws and refreezes over time.
To put it in non-scientific terms, lead scientist Robin Bell told msnbc.com, the study redefines “how squishy” the base of ice sheets can be. “This matters to how fast ice will flow and how fast ice sheets will change.”
“It also means that ice sheet models are not correct,” she said, comparing it to “trying to figure out how a car will drive but forgetting to add the tires. The performance will be very different if you are driving on the rims.”
For the science-based community, this means that climate change models will have to be adjusted in light of this new information. In the conservative-based community this means that Al Gore is fat.
