Climate change news

clouds (missed) and a long lost lake ...

A new paper purportedly debunking the Svensmark hypotheiss, published in the Journal of Climate, follows a similar pattern to other critiques - by apparently ignoring changes to satellite data reception (see http://calderup.wordpress.com/2011/10/05/further-attempt-to-falsify-the-...). The idea appears to be to sidetrack Svensmark before the forthcoming IPCC report - in that way his theory will not be taken into consideration. Anything contrary to the consensus co2 theory is being attacked, the Sun, clouds, the missing heat (escaping into space) etc.

co2 and C14

Sediment cores off the coast of Oregon have revealed that the NW Pacific was not a huge reservoir of co2 during the last Ice Age and could therefore not have hastened the rate of warming - see www.physorg.com/print236864292.html. The paper, published in Nature Geoscience, is somewhat baffling, it claims, as the Pacific,nowadays, is thought to be rich in carbon. Indeed, a recent paper alleged that the missing heat was hiding in the oceans - especially in the Pacific.

Pushing a dead horse ... one and two

At www.physorg.com/print236865130.html there is a report on a paper in Applied Geochemistry that resurrects the issue of acid rain (which died a death a number of years ago) and ocean acidification (a new one on the block). These are scare stories that have been debunked but are regularly regurgitated by environmentalists. In this paper not only is King Coal to blame but the smelting and production of metal ores, various mining processes, and the use of nitrogen as a fertiliser by farmers is given the thumbs down.

How is AGW shaping up in September going on for October?

Well, the media are taking full advantage of current mini heat-wave conditions in the UK - all four days of it. They are implying that records are going to be broken - and as we enter day one of October they have been smashed. Meanwhile, over at Weather Action Piers Corbyn is saying a solar storm will bring lots of rain - which may spoil some of the media excitement. This is now happening - in the northern half of the UK. Piers Corbyn is also forecasting further storms and heavy rain later on in October.

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.
