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

How is the temperature of your pocket useful for meteorology?

I can’t imagine why this project exists. We have thousands of weather stations across the world already. Disentangling the temperature of your pocket from the actual temperature seems like an exercise in futility to me. Even the authors claim they … Continue reading

Climate Craziness of the week – with the physical signature of UHI staring them right in the face, Mann & Borenstein go with their ‘gut’ instincts

Some people wonder if Michael Mann is simply an activist masquerading as a scientist, this lends credence to that idea. I wonder if Dr. Mann has ever visited weather stations in China to understand what is going on there? I … Continue reading

Dr. Michael Mann, Smooth Operator

Guest Post by Willis Eschenbach People sometimes ask why I don’t publish in the so-called scientific journals. Here’s a little story about that. Back in 2004, Michael Mann wrote a mathematically naive piece about how to smooth the ends of … Continue reading

A new buzzword for pushing climate fear? ‘Explosive Cyclones’

After the past weekend’s silliness over a snowstorm that wasn’t all that much different than Nor’Easters of the past, I can imagine some CNN anchor using the phrase badly in the not too distant future, like suggesting sending in a … Continue reading

Dust in the wind: Melt ponds in the Arctic hasten overall melting

I’ve often wondered if carbon soot plays a role in this. See our recent WUWT story about how black carbon’s role has been underestimated, and note that Arctic melting is listed as one of the effects. See also the tag … Continue reading

Arctic temperature amplification takes a hit in GRL

From Wikipedia: Polar amplification is the greater temperature increases in the Arctic compared to the earth as a whole as a result of the effect of feedbacks and other processes. It is not observed in the Antarctic, largely because the … Continue reading

Mercury in California fog linked to ocean upwelling

From the AGU fall meeting in SFO and the University of California – Santa Cruz  comes this rather odd statement that I thought was interesting. It seems like an ecological horror story until you realize it is all natural processes … Continue reading
