Greenland “Ice Melt” a common occurrence!…….that doesn’t stop eco-whackos from writing BS!

Posted: July 25, 2012 in Uncategorized

All the news outlets for the past two weeks have published the fact that Greenland’s Ice Cover has completely melted away and will cause the oceans to rise and the mass extinction of people around the globe!

What a crock of Bull S#1t!

The Global Warmers are so desperate to counter their lies and U.N. fuelled hysteria over the fake Carbon Poisoning of the atmosphere and try and retain any small credibility they “think” they have that they will jump on anything close to a disaster in the making even if it has happened many time before without any serious damage to anyone!

Here’s the true story behind Greenland’s “ice melt” according to REAL SCIENTISTS!

‘Unprecedented’ Greenland Surface Melt – Every 150 Years?

July 25, 2012

Measurements from three satellites showed that on July 8, about 40 percent of the ice sheet had undergone thawing at or near the surface. In just a few days, the melting had dramatically accelerated and an estimated 97 percent of the ice sheet surface had thawed by July 12.

In just a few days, the melting had dramatically accelerated and an estimated 97 percent of the ice sheet surface had thawed by July 12.

The flow of news releases and background science content from NASA is generally excellent, but the space agency badly blew it earlier this week with this headline, which has now reverberated around the Web: “Satellites See Unprecedented Greenland Ice Sheet Surface Melt.”

Unprecedented means “never done or known before.” Yet the news release beneath the headline directly undercuts that description of this melting event, saying that it is rare — the last wide surface melt was in 1889, recorded in separate ice cores at the Greenland ice-sheet summit and in the northwestern part of the vast frozen expanse — and has happened roughly every 150 years over a long stretch of centuries, as recorded deeper in the ice. (Here’s a figure from a 1994 Science paper pointing to a series of such melt layers, reflecting summer warmth. Please see the postscript below for the key reference, provided by Lora Koenig of NASA.)

The inaccurate headline and burst of hyperventilating coverage and commentary (with some exceptions, like this new post by Climate Central) have already provided fodder for those whose passion or job is largely aimed at spreading doubt about science pointing to consequential greenhouse-driven warming.

This is unfortunate because the NASA release otherwise provided a fascinating, timely description of an unusual event, along with the historical context, as in this line:

“Ice cores from Summit 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,” says Lora Koenig, a Goddard glaciologist and a member of the research team analyzing the satellite data. “But if we continue to observe melting events like this in upcoming years, it will be worrisome.”

But subtlety and reality don’t play well in some circles. Koenig’s careful description of the science and the uncertainty about what the future holds prompted a public spanking from the Center for American Progress climate blogger Joe Romm, who charged her with “scientific reticence — alluding to NASA scientist James Hansen’s paper criticizing sea-level researchers for being overly cautious in 2007 conclusions about the possible rate of sea rise in this century. (At the time, scientists focused on ice sheets and sea level pushed back on Hansen’s complaints.)

Hidden in all of this is the value of the important research under way up on the high ice (which I was lucky to visit in 2004; see video below) and using satellites. It’s particularly great to see young scientists able to dig in — literally — on a rare Greenland-wide surface melt event. Also mentioned in the NASA release is the work of Kaitlin Keegan, a doctoral student at Dartmouth College whose focus is “firn,” the newly deposited layers of snow cloaking the two-mile-thick ice sheet that will, over time, become the next dense layers in the great frozen mass. Here’s her blog post on witnessing the first surface melt event since 1889 (with a photo of the resulting ice layer)
