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

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

Dueling press releases on ice melt – one says ‘uncertainty is large’ the other quantifies a number

Once again, it looks like claims of ‘consensus’ are overblown. In our previous news item we have this: …ice sheets are the largest potential source of future sea level rise – and they also possess the largest uncertainty over their … Continue reading

New study using GRACE data shows global sea levels rising less than 7 inches per century

Finds sea levels have risen over the past 9 years [2002-2011] at a rate of only 1.7 mm/yr, equivalent to 6.7 inches per century, matching tide gauge data rates. The paper corroborates the NOAA 2012 Sea Level Budget which finds … 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
