Climate change news

A Sprott on the Landscape

At www.scoop.co.nz/stories/print.html?path=SC0811/S00028.htm ... a press release from the New Zealand Climate Science Coalition on November 11th 2008 can be found at this web address, with the title, How Barycentric Orbits Influence Climate and was made by Dr Jim Sprott, OBE, MSc., PhD., FNZIC, a chemist and forensic scientist in Auckland. He warned the new minister for Climate Change (an AGW advocate) that projections by the IPCC are simplistic, superficial, and wrong etc etc.

July Sea Ice Melt

At http://pgosselin.wordpress.com July 2010 ... is this the slowest melting July since AMSR-E satellite data was recorded (referring to summer ice melt). It has stopped melting he says, and AGWs have their bets on that not happening. They think maximum melt will come in August - still some weeks of counter claim to come. Pierre Gosselin asks why when June was full of media reports about melting ice in the Arctic there is a studied silence on the July figures - or numbers only mentioning the first week of July.

Land and Water, heat and not so heated

http://joannenova.com.au/2010/07/did-giss-discover-30-more-land-in-the-northern-hemishphere/ Frank Lansner has been tinkering with the NASA GISS dataset - trying to understand how it works, or rather, how arch AGW adherent James Hansen gets his numbers. The northern hemisphere has a ratio of 40 per cent land to 60 pere cent ocean, which is used by Hadley CRU in the UK (HadCRU at UEA).

Climate and the sun

www.nguno/en-gb/Aktuelt/2008/Less-ice-in-the-Arctic-ocean-6000-7000-years-ago/ is an article that dates back to October 2008 but is interesting as raised beaches on the north coast of Greenland are said to suggest ice cover in the Arctic Ocean was greatly reduced some 6000-7000 years ago (Astrid Lysa, a Norwegian geologist, and colleage Eiliv Larsen of the NGU, Norway).

Warming event at 40,000 years ago

www.physorg.com/print196606682.html June 24th ... is an interesting article on a rapid warming event 40,000 years ago, which is well documented in palaeo-climate science sources. However, what caused the warming is a matter of debate and this article disputes an earlier study that claimed methane released from ocean sediments was responsible, the co called 'clothrate gun hypothesis'.

C02 and the Oceans

At www.physorg.com/print196059921.html June 18th ... in looking at ice cores from up to 800,000 years ago scientists have found a link between ice melt and C02 abundance in the atmosphere. There has been a 40 per cent increase of C02 in the atmosphere since the last glaciation - and this can largely be attributed, it is being said, to changes in the circulation of oceanic waters surrounding Antarctica.

Dust in the atmosphere

At www.physorg.com/print195145467.html ... in the Proceedings of the National Academy of Sciences it is being said that dust and pollen in the atmosphere causes higher levels of precipitation in clouds. It is now thought clouds have a greater cooling effect on the weather than previously admitted. This change of tack has come about because of extended research into clouds and their role in global warming.

Second Law of Thermodynamics

At http://scienceofdoom.com/2010/05/08/radiation-basics-and-the-imaginary-second-law-of-thermodynamics/ is the second post at this site concerning sceptic arguments that cite the Second Law of Thermodynamics - usually in a puffed and fillibusting manner. The second law is supposed to contradict global warming, and popped up online and in print at American Thinker, a Republican orientated magazine that very often has some interesting articles.

Ho Hum ...

The blogosphere got a bit agitated the other day when 225 members of the American National Academy of Sciences 'paid' for a letter to be published in Science complaining about victimisation by climate sceptics.

Monsoon Vagaries

At http://calderup.wordpress.com May 5th ... Nigel Calder takes up the article on blips in monsoons in recent history (see earlier post in In the News) that includes some severe famines in India, China, and SE Asia (as previously noted). What he adds to the story are solar influences on the monsoons, based on The Chilling Stars hypothesis.
