Transient Van Allen radiation belt discovered

From the University of California – Los Angeles How did a third radiation belt appear in the Earth’s upper atmosphere? Since the discovery of the Van Allen radiation belts in in the Earth’s upper atmosphere in 1958, space scientists have believed that these belts consisted of two doughnut-shaped rings of highly charged particles — an…

AGU says CO2 is plant food

Elevated carbon dioxide making arid regions greener 31 May 2013 AGU Release No. 13-24 WASHINGTON, DC—Scientists have long suspected that a flourishing of green foliage around the globe, observed since the early 1980s in satellite data, springs at least in part from the increasing concentration of carbon dioxide in Earth’s atmosphere. Now, a study of…

Climate models getting worse than we thought

New paper finds climate models are getting worse rather than better Via the Hockey Schtick: A paper published today in Geophysical Research Letters finds that the latest climate models are performing even worse than the earlier generations of climate models in predicting “…both the mean surface air temperature as well as the frequency of extreme…

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 have. I had to laugh when I saw this quote from Mann in Seth Borenstein’s…

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 time series. It was called “On smoothing potentially non-stationary climate time series“, and it was…

Modeling sea level rise is an 'uneven' proposition

From the British Antarctic Survey New projections of ‘uneven’ global sea-level rise Reporting in the journal Geophysical Research Letters researchers have looked ahead to the year 2100 to show how ice loss will continue to add to rising sea levels Sophisticated computer modelling has shown how sea-level rise over the coming century could affect some…

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 involved. Mercury in coastal fog linked to upwelling of deep ocean water SANTA CRUZ, CA–An…
