Year 3, Month 8, Day 5: The Mighty Quinn, Redux.
This is horrifying, in an awful kind of way. The New York Times is one of many reporting on NASA’s recent observations of Greenland, which appears to be melting very fast. Very fast:
In a scant four days this month, the surface of Greenland’s ice sheet melted to an extent not witnessed in 30 years of satellite observations, NASA reported on Tuesday.
The extent of Greenland’s ice sheet surface, in white, on July 8, left, and July 12, right, based on measurements from three satellites, which pass over at different times and whose data are combined and analyzed. The deepest pink areas reflect maximal certainty that the ice has melted.
On average, about half of the surface of the ice sheet melts during the summer. But from July 8 to July 12, the ice melt expanded from 40 percent of the ice sheet to 97 percent, according to scientists who analyzed the data from satellites deployed by NASA and India’s space research institute.
“I started looking at the satellite imagery and saw something that was really unprecedented” since the advent of satellite imaging of the earth’s frozen surface, or cryosphere, said Thomas L. Mote, a climate scientist at the University of Georgia who for 20 years has been studying ice changes on Greenland detected by satellite.
While scientists described it as an “extreme event” not previously recorded from space, they hastened to add that it was normal in a broader historical context.
But Al Gore is fat. Sent July 25:
When it comes to the news on climate change, “rare” seems to be the new “often.” How often in the recent past have we heard reports of “once-in-a-century” storms suddenly happening every year? Of nearly snowless winters several times in a row — in places normally measuring the stuff in yards?
NASA’s report of unprecedented melting on Greenland’s ice sheet is just the latest and most terrifying example of this phenomenon. While the researchers studying the ice discuss it in careful scientific language, there’s no doubt they are shocked and disturbed by such extreme melting.
How much more evidence do we need to connect the accelerating greenhouse effect to these stunning disruptions of the environmental status quo? Our civilization was made possible by a mild and predictable climate — one rapidly vanishing in the rear-view mirrors of our industrial-size SUVs. Now that “bizarre” is the new “normal”, whither humanity?
