Camp Century Greenland: 8m Under The Ice in 1959 and 35m Under The Ice in 2016

Published on January 5, 2019January 5, 2019 by sunshinehours12 Comments

Interesting article about Camp Century.

Howerever the funny part is where the Guardian tries to claim that “climate change” is going too melt the ice and expose radioactive materials when in fact the ice cover has gone from 8m in 1959 to 27m in 2016.

I don’t see any melting!

The US army engineering corps excavated Camp Century in 1959 around 200km (124 miles) from the coast of Greenland, which was then a county of Denmark.

Powered, remarkably, by the world’s first mobile nuclear generator and known as “the city under the ice”, the camp’s three-kilometre network of tunnels, eight metres beneath the ice, housed laboratories, a shop, a hospital, a cinema, a chapel and accommodation for as many as 200 soldiers.

400,000 years ago – All of Greenland Melted – No SUVs

Published on March 23, 2017 by sunshinehours128 Comments

The interglacial ~400,000 years ago was lot hotter. And there were no SUVs or coal power plants.

“A paper published … in Palaeogeography, Palaeoclimatology, Palaeoecology finds that the last 4 interglacials were up to 3C warmer than the current interglacial and were characterized by sea levels up to 79 feet [24 meters] higher than the present. According to the authors, “The most conservative estimates of palaeo-sea level during [the interglacial ~400,000 years ago] would require an ice mass loss equivalent to all of the modern Greenland and West Antarctic ice sheets; the more extreme estimates would require additional ice mass loss from the East Antarctic ice sheet.”

Thus, during prior interglacials, sea surface temperatures were up to 3 °C warmer, sea levels were up to 79 feet higher than the present, and up to all of the Greenland and West Antarctic ice sheets melted away. All of this occurred naturally and at “safe” levels of CO2. Thus, there is no evidence that climate change within the present interglacial is any different, unprecedented, unnatural, unusual, or due to man-made CO2.”

Greenland Ice Balance Well Above Normal

The daily surface mass balance on the Greenland Ice Sheet is well above normal.

Greenland is melting! 40 Trillion Pounds A Year!!!! Ooops.

Greenland is melting!!!

40 Trillion Pounds a Year!!!

Ooops. A trivial amount.

The extra ice loss adds a tiny amount — one-sixtieth of an inch (0.4 mm) a decade — to global sea level rise, Bevis said.

Altogether, Greenland melt adds one fiftieth of an inch — 0.54 mm— a decade, he said.

Record COLD Reported In Greenland

Published on August 7, 2016 by sunshinehours15 Comments

Brrrrrrr.

On August 1, the Danish Meteorological Institute’s measuring station registered an appalling -30.7 ° C at the ice cap’s summit.

“This is the lowest temperature for July we have from this station,” said John Cappelen.

The previous record was -27.7 ° C on 30 July 1992.

Greenland Melting: Broken Satellite ‘Confirms’

Published on April 13, 2016April 13, 2016 by sunshinehours1Leave a comment

I was reading this article on Greenland melting. And then I read this:

Meier is (I assume) Walt Meier of the NSIDC.

Ok … so the satellite that was producing spurious massive jumps in Arctic/Antarctic Sea Ice is being used to confirm the melting of Greenland despite being told the satellite is broken.

Yup. Sounds typical.

On Monday and Tuesday, about 12 per cent of the ice sheet surface area — 656,000 square miles or 1.7 million square kilometers — showed signs of melting ice, according to Peter Langen, a climate scientist at the Danish Meteorological Institute.

This is the DMI graph of the arctic sea ice extent using data from the same satellite … I think.

Wait. This just in.(I’m flabbergasted).

Greenland Surface Melt dataset produced by:

DMSP 5D-2/F11, DMSP 5D-2/F13, DMSP 5D-2/F8, DMSP 5D-3/F17, NIMBUS-7

F17 is the satellite producing spurious sea ice data.

Glacier Girl

Published on April 10, 2016April 10, 2016 by sunshinehours13 Comments

This is a nice set of pictures I’d never seen before.

On 15 July 1942, due to poor weather and limited visibility, six P-38 fighters of 94th Fighter Squadron/1st FG and two B-17 bombers of a bombardment squadron were forced to return to Greenland en route to the British Isles during Operation Bolero, the buildup of American forces in the United Kingdom.

The aircraft were forced to make emergency landings on the ice field. All the crew members were subsequently rescued. However, Glacier Girl, along with the unit’s five other fighters and the two B-17s, were eventually buried under 268 feet of snow and ice that had built up over the ensuing decades.

Fifty years later, in 1992, the plane was brought to the surface by members of the Greenland Expedition Society after years of searching and excavation.

Earth’s Internal Heat Drives Subglacial Melting in Greenland

Published on April 5, 2016April 5, 2016 by sunshinehours1Leave a comment

This is pretty amazing.

Greenland’s lithosphere has hot depths which originate in its distant geological past and cause Greenland’s ice to rapidly flow and melt from below.

To understand Greenland’s ice of today researchers have to go far back into Earth’s history. The island’s lithosphere has hot depths which originate in its distant geological past and cause Greenland’s ice to rapidly flow and melt from below. An anomaly zone crosses Greenland from west to east where present-day flow of heat from the Earth’s interior is elevated. With this anomaly, an international team of geoscientists led by Irina Rogozhina and Alexey Petrunin from the GFZ German Research Centre for Geosciences could explain observations from radar and ice core drilling data that indicate a widespread melting beneath the ice sheet and increased sliding at the base of the ice that drives the rapid ice flow over a distance of 750 kilometres from the summit area of the Greenland ice sheet to the North Atlantic Ocean.

The North Atlantic Ocean is an area of active plate tectonics. Between 80 and 35 million years ago tectonic processes moved Greenland over an area of abnormally hot mantle material that still today is responsible for the volcanic activity of Iceland. The mantle material heated and thinned Greenland at depth producing a strong geothermal anomaly that spans a quarter of the land area of Greenland. This ancient and long-lived source of heat has created a region where subglacial meltwater is abundant, lubricating the base of the ice and making it flow rapidly. The study indicates that about a half of the ice in north-central Greenland is resting on a thawed bed and that the meltwater is routed to the ocean through a dense hydrological network beneath the ice.

The team of geoscientists has now, for the first time, been able to prove strong coupling between processes deep in the Earth’s interior with the flow dynamics and subglacial hydrology of large ice sheets: “The geothermal anomaly which resulted from the Icelandic mantle-plume tens of millions of years ago is an important motor for today’s hydrology under the ice sheet and for the high flow-rate of the ice” explains Irina Rogozhina. “This, in turn, broadly influences the dynamic behaviour of ice masses and must be included in studies of the future response to climate change.”

Greenland remained stable for 2.7 million years “even during the warmest periods”

2.7-Million-Year-Old Forested Landscape Discovered under Greenland Ice Sheet

“We found organic soil that has been frozen to the bottom of the ice sheet for 2.7 million years,” said Dr Paul Bierman, a geologist with the University of Vermont and the lead author of the paper appearing online in the journalScience.

“The ancient soil under the Greenland Ice Sheet helps to unravel an important mystery surrounding climate change – how did big ice sheets melt and grow in response to changes in temperature?” said co-author Dr Dylan Rood from the Scottish Universities Environmental Research Center and the University of California, Santa Barbara.

The discovery indicates that even during the warmest periods since the ice sheet formed, the center of Greenland remained stable.“

“Greenland really was green! However, it was millions of years ago. Greenland looked like the green Alaskan tundra, before it was covered by the second largest body of ice on Earth,” Dr Rood said.
