UPDATE: I’ve added a comment by Marcel Crok to the end of the post. #### The climate models being used by the IPCC for their upcoming 5th Assessment Report show little skill at being able to simulate a number of variables. We can now add Scandinavian land surface air temperature anomalies to the list. Figure…
From The Hockey Schtick A paper published Tuesday in the Journal of Climate finds tiny variations in solar activity over 11-year solar cycles have greatly amplified effects upon climate via changes in the Arctic Oscillation, North Pacific sea surface temperatures & sea level pressure, and via changes in stratospheric ozone from solar UV. The authors…
By Paul Homewood It seems that every time we get some snow, another “scientist” is wheeled out to explain that, no matter how cold it gets, it is all down to global warming. In the last week or so, we have had the International Arctic Research Centre announcing a study by three Chinese scientists, “Weakened…
Guest post by Dr. Walt Meier, National Snow and Ice Data Center Winds, Temperatures, and Arctic Sea Ice Extent As the summer sea ice melt season gets into high gear, I thought I’d do a post on sea ice processes and other tidbits about sea ice that may be useful as people watch the seasonal…
By WUWT regular “Just The Facts” A June 16th article in the Economist “The vanishing north” states that; “Between now and early September, when the polar pack ice shrivels to its summer minimum, they will pore over the daily sea ice reports of America’s National Snow and Ice Data Centre. Its satellite data will show…
From the University of Washington Russian river water unexpected culprit behind Arctic freshening near US, Canada A hemisphere-wide phenomenon – and not just regional forces – has caused record-breaking amounts of freshwater to accumulate in the Arctic’s Beaufort Sea. Freshwater Pathway Frigid freshwater flowing into the Arctic Ocean from three of Russia’s mighty rivers was…
By Joseph D’Aleo, CCM, AMS Fellow The arctic ice appears to have bottomed out at a level 6.4% higher than the 2007 record. Mark Serreze of the National Snow and Ice Data Center says the Arctic could be ice-free in the summer by about 2030, though that is hard to predict; other scientists say it…
The SeaWiFS instrument aboard the Seastar satellite has been collecting ocean data since 1997. By monitoring the color of reflected light via satellite, scientists can determine how successfully plant life is photosynthesizing. A measurement of photosynthesis is essentially a measurement of successful growth, and growth means successful use of ambient carbon. This animation shows an…
Guest post By Joseph D’Aleo, CCM, AMS Fellow Mother Nature for the second year in a row is sending a message to alarmists in the government and the media. Another snowstorm has swept across the nation and focused its fury on the northeast corridor. Last year it was the Mid-Atlantic, the political center that was…
Guest post by Erl Happ The Northern Hemisphere is having an old fashioned winter. I thought it might be of interest to look back at history for any lessons that might be there. I think that we already have enough data to work out what drives the climate system. The Arctic Oscillation Index compares mid…
