The latest round of international climate change talks finished on Friday in discord and disappointment, with some participants concerned that important progress made last year was being unpicked.

At the talks, countries were supposed to set out a workplan on negotiations that should result in a new global climate treaty, to be drafted by the end of 2015 and to come into force in 2020. But participants told the Guardian they were downbeat, disappointed and frustrated that the decision to work on a new treaty – reached after marathon late-running talks last December in Durban – was being questioned.

--------------------

For those of us who pay attention to details and specifics, there is some big pseudo-scientific traps set up by denialists of global warming... For example, this caper from an outfit that calls itself the "Science and Public Policy Institute":

WASHINGTON (7-15-08) - Mathematical proof that there is no “climate crisis” appears today in a major, peer-reviewed paper in Physics and Society, a learned journal of the 46,000-strong American Physical Society, SPPI reports.
Christopher Monckton, who once advised Margaret Thatcher, demonstrates via 30 equations that computer models used by
the UN’s climate panel (IPCC) were pre-programmed with overstated values for the three variables whose product is
“climate sensitivity” (temperature increase in response to greenhouse-gas increase), resulting in a 500-2000% overstatement of CO2’s effect on temperature in the IPCC’s latest climate assessment report, published in 2007.

----------------------------------

But if one reads about the American Physical Society (APS), one soon discovers that it's not at all the case, and the publication "there" (I can't find it, nor can I find the names of the "peers" who reviewed it) by Lord Monckton was a bit suspect.... The APS is a respected organisation that:

-----------------------------

In 2007, APS adopted an official statement on global warming:[9]

Emissions of greenhouse gases from human activities are changing the atmosphere in ways that affect the Earth's climate. Greenhouse gases include carbon dioxide as well as methane, nitrous oxide and other gases. They are emitted from fossil fuel combustion and a range of industrial and agricultural processes.

The evidence is incontrovertible: Global warming is occurring.

If no mitigating actions are taken, significant disruptions in the Earth’s physical and ecological systems, social systems, security and human health are likely to occur. We must reduce emissions of greenhouse gases beginning now.

Because the complexity of the climate makes accurate prediction difficult, the APS urges an enhanced effort to understand the effects of human activity on the Earth’s climate, and to provide the technological options for meeting the climate challenge in the near and longer terms. The APS also urges governments, universities, national laboratories and its membership to support policies and actions that will reduce the emission of greenhouse gases.

In November 2009, 80 current and past members of the American Physical Society presented a letter to the society specifically objecting to the society's position.[10] A few days later, it was rejected.[11] On April 18, 2010, the APS modified the policy statement significantly toning down the rhetoric.[9]

The following individuals resigned their memberships over disagreement with the society's official statement on global warming:

• Ivar Giaever, Winner of the Nobel Prize for Physics in 1973, resigned 13 September 2011.[12]
• Harold Lewis, Emeritus Professor of Physics and former department chairman at the University of California, Santa Barbara, resigned 6 October 2010.

2 resignations out of 46,000 is small potatoes, even if one of them is a Nobel prize winner... Nobel prize winners can be wrong, should they decide to be so and ignorant of the facts in fields in which they have no expertise in. As well, physics plays a part in the CHEMISTRY of the atmosphere, but the ignorance of the chemistry — or that of mixture of gases in an environment — is far more a bigger problem. Lord Monckton went for broke and presented some mighty bullshit with great confidence when in his paper, he said:

The IPCC’s 2007 climate summary overstated CO2’s impact on temperature by 500-2000%;
CO2 enrichment will add little more than 1 °F (0.6 °C) to global mean surface temperature by 2100;
Not one of the three key variables whose product is climate sensitivity can be measured directly;
The IPCC’s values for these key variables are taken from only four published papers, not 2,500;
The IPCC’s values for each of the three variables, and hence for climate sensitivity, are overstated;
“Global warming” halted ten years ago, and surface temperature has been falling for seven years;
Not one of the computer models relied upon by the IPCC predicted so long and rapid a cooling;
The IPCC inserted a table into the scientists’ draft, overstating the effect of ice-melt by 1000%;
It was proved 50 years ago that predicting climate more than two weeks ahead is impossible;
Mars, Jupiter, Neptune’s largest moon, and Pluto warmed at the same time as Earth warmed;
In the past 70 years the Sun was more active than at almost any other time in the past 11,400 years..

Of course all the points above can be disproved in a jiffy by serious analysis, considering that surface temperatures ARE STILL warming up...

After achieving record annual temperatures on Friday, much of Britain is expected to bask in the warm afterglow of summer temperatures and enjoy a "barbecue weekend".

SCOTLAND enjoyed a burst of summer sunshine yesterday, after temperatures came close to beating the all-time May record.

Altnaharra in the Highlands was the hottest place in the Scotland, with 27.3C yesterday lunchtime, closely followed by the ski resort of Aviemore, where it reached 26.9C.

In Glasgow, which basked in temperatures of 23.1C, sun-worshippers were seen splashing in the Victorian Stewart Memorial Fountain in Kelvingrove Park, joined by a couple of dogs trying to cool down. At Blair Drumomnd Safari Park near Stirling, keepers gave the elephants a cooling spray bath with hoses.

Of course there are more denialist scientists around and I will mention and will refute them in the next comments.
