Climate change news

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.

Cycles

The idea of solar cycles or any kind of weather cycle is discussed at Judith Curry's web site Climate Etc, www.judithcurry.com/2011/07/27/cyclomania/ and at Tallbloke's Talkshop at http://tallbloke.wordpress.com/2011/02/21/tallbloke-and-tim-channon-a-cy.... Are such cycles imaginary, a product of computers, or are they real and even if they are how far back into the past can they be extrapolated? The comments on both sites are interesting as the posts are designed to get the commenters on song.

The Consensus

At http://judithcurry.com/2011/07/16/manufacturing-consensus/ there is a post with hundreds of comments on the AGW consensus. Judith Curry is a published climate scientist whose aim is to open a dialogue with sceptics, in an attempt to bridge the gulf. It seems one of Peter Warlow's villains was responsible. Worth reading.

Growing glaciers, missing heat and ethanol

At www.physorg.com/print229770933.html we have a new study in Environmental Research Letters July 5th that claims it will get hotter even than the extravagant claims made by the IPCC - all down to modelling efficiencey. At http://wattsupwiththat.com/2011/07/12/the-grass-is-greener-on-the-ethano...  ... another story common to a lot of sites (such as www.physorg.com/print229685676.html) and concerns agriculture's contribution to AGW.
