Climate change news

North Atlantic Weather

At www.sciencedaily.com/releases/2011/03/110330131306.htm scientists have been finding out why it is cold in NE America but not in NW Europe at the same latitude (a paper in Nature, March 31st 2001). It is 10 degrees Fahrenheit warmer in NW Europe than it is on the opposite side of the Atlantic. It seems the same thing occurs in the Pacific where winters in the Vancouver and Seattle region are mild in comparison with the same latitude on the eastern side of the ocean.

Climate Update as we head towards the end of March

Over at www.weatheraction.com Piers Corbyn is predicting some extreme weather or even an earthquake in the next few days - as a result of solar activity. Meanwhile, at www.physorg.com/print220262708.html we learn that sea ice extent is at nearly its lowest point - ever (or since the modern AGW phenomenon took root some 25 to 30 years ago). However, at http://stevengoddard.wordpress.com/2011/03/25/huge-increase-in-thick-ice... where we learn the opposite side of things. It is not the extent that matters, it is being argued, but the thickness of the ice.

The Earth is Greening

At http://wattsupwiththat.com/2011/03/24/the-earths-biosphere-is-booming-da... ... global warming or not the earth's biosphere appears to be benefiting from increased C02 in the atmosphere - the earth is greening. This post is based on one paper by three Chinese scientists, Liu et al, 'Spatial and temperal variations of global LAI during 1981-2006' in the Journal of Geophysical Sciences 20 (2010) - the LAI in this instance stands for Leaf Area Index.

Green fuel

At www.telegraph.co.uk/earth/earthnews/8398320/Jatropha-biofuel-produces-si... March 22nd. The headline says it all - this particular biofuel creates more C02 than burning coal or oil. Third world countries are being encouraged by green western governments to reduce emissions and bring a halt to the destruction of rainforest - or any other wild and green place.

The Sun and global warming theory

There is a lovely post at http://wattsupwiththat.com/2011/03/22/does-solar-activity-have-to-keep-g... ... basically, it has been assumed that solar activity was not trending upwards, a situation endlessly trotted out by climate scientists that had the goal of negating solar activity as a cause of the 1990s/early 2000s spike in global temperatures.

Global Warming on Mars

At www.physorg.com/print219842545.html there is a story, 'Chasma Boreale, Mars' with an image supplied by NASA. The chasm is a long flat floored valley that cuts deep into the Mars polar ice cape. Its walls rise up 4600 feet and it seems the ice has retreated as sheets of sand are emerging that accumulated in earlier ice free periods. The depiction comes from images taken between 2002 and 2005 by the Thermal Emissions Imaging System onboard the Mars Odyssey spacecraft. Melting ice on Mars appears to replicate melting mountain glaciers on the earth - why?

Disappearing the contrarians

Although this story was flying around the blogosphere a few weeks ago it never reached much of a drama - and it is still quite low key. However, the day may well be coming when Google loses its golden shine and that aura of all things bright and wonderful.

Ozone and Meltdown

A couple of doomsayings - or what might be called some mischief making from environmentalists. Apparently, an ozone hole has developed this week over the Arctic and is said to be a big problem - blamed on unusually cold temperatures in the Arctic. Firstly, you may note the disappearance of ozone coincides with a couple of very big solar flares and auroral displays at the Poles but that is of no consequence, it seems (see http://wattsupwiththat.com/2011/03/15/my-morning-double-take-arctic-on-t... ).

Household Lighting and the Earth Hour

An interesting post at http://colinmcinnes.blogspot.com/2011/03/dimming-light-of-human-ingenuity.html is all about the history of lighting houses over the last couple of hundred years. It progresses from candles to oil lamps fueled by cooking whales. The discovery of fossil oil was a reprieve for the whale but was closely followed by the discovery of electricity and the much maligned light bulb, the object of derision by more extreme elements of AGW enthusiasm.

New Paper - Arctic Sea Ice Rebounds

At www.sciencedaily.com/releases/2011/02/110204092149.htm ... 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.
