Enormous Aquifer Discovered Under Greenland Ice Sheet

From NASA, I had to laugh at this statement: The water in the aquifer has the potential to raise global sea level by 0.016 inches (0.4 mm). That’s assuming it can get out sometime in the distant future. Greenland’s topography … Continue reading

Lakes discovered beneath Greenland ice sheet

From the University of Cambridge The subglacial lakes are the first to be identified in Greenland The study, published in Geophysical Research Letters, discovered two subglacial lakes 800 metres below the Greenland Ice Sheet. The two lakes are each roughly … Continue reading

Study: Greenland Ice Sheet was smaller 3000-5000 years ago than today

From the University of Buffalo Clues in the Arctic fossil record suggest that 3-5,000 years ago, the ice sheet was the smallest it has been in the past 10,000 years Summary: Ice sheets are like bulldozers. As they grow, they … Continue reading

Oh, what a difference a year makes in Greenland melting

ARCTIC SUMMER SNOWSTORM By Joseph D’Aleo CCM Remember a year ago when few days of July ‘warmth’ with strong blocking over Greenland had the media abuzz over some melting? Last July a brief spell of temperatures in the mid 30s … Continue reading

NOAA exaggerates 2012 Greenland Ice Mass Loss by 10x

[UPDATE: Several commenters, including myself, have remarked on a mathematical error in the author's work. I note this here in the expectation that the author will return to clarify and perhaps amend his claims. Having made such public mistakes myself, … Continue reading

Remember that ‘unprecedented’ Greenland ice sheet surface melt that was allegedly caused by global warming? Never mind

We covered this extensively at WUWT last summer, including the “unprecedented claim” where a researcher said it was a recurring 150 year event that was ‘right on time‘. It turns out jet stream changes and thin cloud cover was the … Continue reading

Hansen falsified: His extreme sea level rise projections are drowning in hubris

After yesterday’s tongue-in-cheek mention of Obama’s healing the planet (and sea level rise with it) here’s the real lowdown on the current knowledge. It seems that all the science that Hansen uses to base his 5-6 meter sea level rise … Continue reading

Global warming and the Titanic II – on an epic collision course?

People send me stuff. This morning I got a note about a new study that says: Over the past decade, ice-loss from the Greenland Ice Sheet has been accelerating, raising concerns about runaway losses and consequent sea-level rise. But research … Continue reading

Weather, not climate, caused the brief surface melt in Greenland last summer

Readers may recall the breathless wailing over a brief period of surface melt detected by satellites last year. The way the media and alarmists who drive the media behaved, you’d think that global warming had set the planet on fire. … Continue reading

Greenland ice melt overestimated due to satellite data algorithm issue

This is an interesting admission: The melt extent algorithm used by Greenland Ice Sheet Today has been overestimating the melt extent, and as a result, daily images posted on this site in February and March may have indicated melt where … Continue reading

First complete ice core record of last interglacial period shows the climate of Greenland to be significantly warmer than today

Study: ‘ Greenland ice sheet is not as sensitive to temperature increases and to ice melting and running out to sea in warm climate periods ‘. From the University of Copenhagen Greenland ice cores reveal warm climate of the past … Continue reading

Making Hay of sea level rise estimates

People send me stuff. You may recall this story from last week that raised a number of eyebrows due to the claims made within it by author William Hay. Dave Burton decided to take him to task. So far no … Continue reading

Greenland Ice Melt every 150 years is ‘right on time’

UPDATE: see this new article on the issue, “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,” … Continue reading
