Climate change news

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.

Hacked phones ... and Climategate

Its beginning to look like the implosion by the press as a result of the News of the World 'dodgy practises' might in the end shed a shaft of light into the politics of Climategate. A certain individual, a spinmeister by trade, implicated in the affair, seems not to just have been employed by the police in the battle to counter terrorism but was also hired by the University of East Anglia in the wake of the Climategate email leak. Basically, his role was as a PR advisor, deflecting the blogosphere that had gone ballistic after the release of those emails.

Volcanoes

It seems that volcanic aerosols may be under-estimated when it comes to global temperatures. Research in France has just been published by PNAS (July 2011) (see http://wattsupwiththat.com/2011/07/11/new-study-suggests-that-the-volcan... ). What caught my attention in this post is the possibility that aerosols may play a role in the cool weather of the Little Ice Age (but unsaid).

Two Times Mann

It seems we have two climate scientists with the monicker of Michael Mann (but with different middle names). This emerged with the publication of a paper where the 'other' Michael Mann was a co-author of the Kaufmann et al release that has admitted, for the first time, that global surface temperatures did not rise between 1998 and 2008 (ignoring the last couple of years) (see http://wattsupwiththat.com/2011/07/04/a-peer-reviewed-admission-that-glo... ).
