Climate models - how they might differ

In a comment at www.drroyspencer.com/2011/09/a-primer-on-our-claim-that-clouds-cause-tem... ... Richard Courtney outlines some research on climate models he did ten years ago and some follow-up papers by others, since then. He says none of the models (the IPCC tracks 20 of them) could match mean global average temperatures in teh 20th century if they did not make use of an assumption, namely that cooling is caused by aerosols in the atmosphere. Hence, all the models input a cooling effect on past temperatures - which they might describe as a mysterious impact from clouds.

Climate ... frantic seesaw

At http://wattsupwiththat.com/2011/09/05/cet-vs-meto-a-problem-with-tempera... is a bit of a cheeky pieces that asks why the Met Office temperatures for the peripheries of Britain are somewhat warmer than the central region of the country. The Central England Temperature series shows cooler temperatures than the Met Office data which may indicate its super computer has an inbuilt AGW bias. It is amazing this has not been rectified as they have repeatedly been criticised for using a data series that is not up to scratch.

Climate update first week in September

At http://thegwpf.org/the-observatory/3779-henrik-svensmark-the-cosmic-rayc... ... Henrik Svensmark, co-author of The Chilling Stars, answers some questions posed to him by GWPF. It seems that solar flares send out plasma clouds that shield the earth and cause the cosmic ray influx to go down - within half a day. This affects cloud formation.

More cold water poured on AGW science

This time it emanates from a paper by Lindzen and Choi - see http://wattsupwiththat.com/2011/08/16/new-paper-from-lindzen-and-choi-im... and claims c02 influences global temperature on a much lower scale than consensus climate science allow. In fact, their conclusion is that current modelling exaggerates climate sensitivity - some of the models, greatly so. The full paper can also be accessed at Lindzen's personal web space at http://www-eaps.mit.edu/faculty/lindzen/236-Lindzen-Choi-2011.pdf

Climate on the blogs this week

Sceptic blogs have been gnawing away at the discovery that some of the leading phone hackers from the mainstream media were hired by the University of East Anglia to indulge in a bit of damage limitation after the Climategate email leak, presumably in order to hack the phones of likely suspects. The fact the source of the leak has never been disclosed almost certainly means it was internal - and the university hired a PR company led by personalities closely involved in the recent hacking rumpus.

Sea Ice, drought ...

At www.physorg.com/print231687171.html ... a paper in Science (August 5th) by Danish researchers from the University of Copenhagen has looked at summer sea ice in the Arctic Ocean throughout the Holocene (roughly the last 10,000 years). For the period 6000-3000BC, known as the Mid Holocene Warm Period, there was far less sea ice in the Arctic Ocean and the coast of northern Greenland was buffeted by waves. 

Question mark over c02 - human or natural?

The domino effect predicted that once the CAGW hypothesis began to unwind  new papers would come thick and fast and bury the idea in a terminal fashion. We might ask is this now happening as following close on the heels of the paper by Professor Roy Spencer we have this story at http://joannenova.com.au/2011/08/blockbuster-planetary-temperature-contr... which is a report on a speech by Professor Murry Salby at the Sydney Instiitute, 'Global emissions of carbon dioxide: the contributions from natural sources.

Panning out ....

As record sea ice melt this summer appears to have stalled we also learn that Scandinavian lakes during the 1970s and 1980s were not as acidified as environmental activists at the time got into a tizzy about - blaming the British coal industry and putting thousands of miners out of work (see www.physorg.com/print231391630.html ). See also www.dailygalaxy.com on July 12th - is Venus the Ultimate poster child for Global Warming?

Peter Warlow was right - NASA satellite says so

Peter Warlow, who was due to speak at the 2011 SIS autumn speaker meeting, also gave a talk in 2009, on April 25th at the Harlequin theatre in Redhill, with the title, 'Global Warming Nonsense' and was adamant that the greenhouse theory was flawed. At www.physorg.com/print231155725.html we learn that NASAs Terra satellite has shown climate models are in error - and a greater amount of heat is lost to space than they are programmed to remit.

Extreme Weather anomalies over 2000 years

At the nicely named web site www.breadandbutterscience.com there is a pdf of over 500 pages of text with the title, 'A chronological history of early weather events' by James Marusek (2010) as a counter to AGW hype concerning modern weather extremes - which are supposed to be coming thick and fast as a result of rising C02 levels. This composition shows that such a point of view is really rather juvenile and not worth commenting on to be truthful.
