New Paper - Arctic Sea Ice Rebounds

At ... a paper in Geophysical Research Letters 2011: 38 claims that recovery mechanisms of Arctic summer sea ice shows that no tipping point is likely to exist as far as the loss of Arctic sea ice is concerned. In the summer it melts by varying amounts, sometimes more and sometimes less. However, each winter the sea ice recovers - and always will.

Hide the Decline

At ... if you never understood what the fuss was about in 'hiding the decline' in the Climategate emails read this piece by a climate scientist fed up with the small number of other climate scientists who have exagerated the warming trend. The comments at the end of the piece are approaching 2000 in  number - she has bit the bullet and people are squirming on one side, and are elated on the other.

Lake Baikal and the weather

At Lake Baikal, the worlds biggest lake, we learn is cold and deep and is giving up some of its secrets. A study in PLoS One (February 2011) by Russian scientists has found that water temperatures in the past correlate with El Nino indices and actually reflect sea surface temperatures in the Pacific - yet Lake Baikal is in Siberia.

Bananas and radiation

At there is a nice post from Anthony Watts on bananas containing radiation. Apparently, several foods are naturally radioactive and bananas in particular due to potassium-40. The point is that fear of radiation leaking from nucleur power stations has been over-hyped as there is a lot of radiation out there in the human world - especially if you live somewhere like Cornwall.

Random Walks

At ... this is a guest post by lukewarmer Roger Pielke Senior with an amusing title on a paper by Fraudrich, Kirk, Schubert and Zhu (2011), 'Random Walk lengths of about 30 years in global climate'. They examine the choice of 30 year data sets which goes back to the early 20th century.

The Revision of History

AGW proponents not only adjust temperature readings from the recent past in order to draw a more prominent warming trend they are now revising history itself in order to saddle the wicked human race with further angst. According to the new history of the world the Roman Empire, the Black Death, and the colonisation of the Americas had a significant impact on climate - largely it seems by chopping down trees.

Tree Ring Study

At there is a post on an article in New Scientist of January 14th commenting on a paper by Buntgen et al that was actually published in Science (DOI: 10.1126/science.1197175.htm ).

Iceland Volcanoes

At the Modern Survival blog it is being suggested the Katla volcano on Iceland, the really big one, is displaying signs of activity. A ring of earthquakes on the western rim of the Myrdalsjokull glacier may indicate Katla is rumbling underneath. This subject has not reached the ears of mainstream media and the continuing problems that Russian ice breakers have been having in trying to rescue fishing boats and factory ships in the Arctic is also ignored - in spite of the fact that 500 lives are at risk.

The Quelccaya Glacier

At January 3rd ... we learn that freezing weather is also affecting the tropics - in this instance, the high mountain zones of the tropics. Ecuador is both tropical but also the Andes heights harbour glaciers - most noteably the famous Quelccaya glacier that environmentalists have been so fond of telling us over the last 20 years or so, is receding. In other words, it has been melting. It has melted to such a degree that plants that were buried under ice thousands of years ago have been found, relatively intact.

Oz and the weather

At ... we have some nice pictures of snow in Australia - in December. It's supposed to be summer down under but some icy gusts have swept up from the Southern Ocean and tickled the east coast states of NSW and Victoria. Ski resorts have benefited - so we are talking about high ground, the Snowy Mountains perhaps. Still, even in Sydney the temperatures are said to have fallen.
