Well, it seems something else causes Global Warming: bad sensors.
A glitch in satellite sensors caused scientists to underestimate the extent of Arctic sea ice by 500,000 square kilometers (193,000 square miles), a California- size area, the U.S. National Snow and Ice Data Center said.Remember poor Mrs. Polar Bear and her cubs, drowning in the ice-free ocean? Oops.
But don't worry, there's an explanation:
Walt Meier writes with a clarification: “One detail, though perhaps an important [one]. I realize that it is bit confusing, but it is just one channel of the sensor that has issues. And it isn’t so much that it “failed”, but that quality degraded to the point the sea ice algorithm - the process to convert the raw data into sea ice concentration/extent - failed on Monday.See, it wasn't the sensor that failed, it only degraded. It was the computer model that failed. But it's a different model than the ones that show the earth is irreversibly warming, so don't worry.
Hey you deniers! Get the heck off my lawn!
