Massive Ice Melt In Greenland Worries Scientists
Scott Neuman | July 25,2012 | NPR


I am not fully schooled on what is really happening to the earth regarding cooling/warming? So I present the facts concerning Greenland, as they are presented to me. (July 26, 2012)

'A pair of NASA satellite images taken just four days apart tells a potentially worrying story of melting ice in the polar summer.

Images released Tuesday show the extent of surface melt on Greenland's ice sheet on July 8 (left) and July 12 (right).
Measurements from three satellites showed that on July 8, about 40 percent of the ice sheet had undergone thawing at
or near the surface. By July 12, 97 percent of the ice sheet surface had thawed.


The first, snapped from orbit on July 8, shows about 40 percent of the Greenland ice sheet shaded in pink or red to illustrate probable or confirmed surface melting. The second photo, taken on July 12, shows nearly the entire land mass — 97 percent — blotched in a red hue.

In a typical year, only about half of the Greenland ice sheet undergoes this kind of melting before it later refreezes. But the rapidity and extent of the July change is what has caught scientists off guard, said Thomas Mote, a professor at the University of Georgia, who helped confirm the data from three satellites.'

Yet more alarmism from the warmist camp.

In fact, a 4-day (first and likely only occurrence this summer) heat-wave of single digit C temps. This caused some surface meltiing (for the first time this summer) over most of Greenland. Things are back to "normal" as can be seen on any of the webcams from there.

In fact, this is an unusual but regular feature of the area. Every 150 years or so, the same thing happens and has been for thousands of years, based on O2 isotope analyses of temperatures.

“Ice cores from Summit station [Greenland’s coldest and highest] show that melting events of this type occur about once every 150 years on average. With the last one happening in 1889, this event is right on time,” said Lora Koenig, a Goddard glaciologist and a member of the research team analyzing the satellite data.


Desperation from a dying meme.
