The consensus continues to unravel

Via Watt's Up With That, here is a letter, from American Physical Society member Roger W. Cohen, in support of Lord Monkton's paper; as Climate Skeptic points out, it's practically a mission statement for his blog.
I retired four years ago, and at the time of my retirement I was well convinced, as were most technically trained people, that the IPCC’s case for Anthropogenic Global Warming (AGW) is very tight. However, upon taking the time to get into the details of the science, I was appalled at how flimsy the case really is. I was also appalled at the behavior of many of those who helped produce the IPCC reports and by many of those who promote it. In particular I am referring to the arrogance; the activities aimed at shutting down debate; the outright fabrications; the mindless defense of bogus science, and the politicization of the IPCC process and the science process itself.

At this point there is little doubt that the IPCC position is seriously flawed in its central position that humanity is responsible for most of the observed warming of the last third of the 20th century, and in its projections for effects in the 21st century. Here are five key reasons for this:
  1. The recorded temperature rise is neither exceptional nor persistent. For example, the earth has not warmed since around 1997 and may in fact be in a cooling trend. Also, in particular, the Arctic and contiguous 48 states are at about the same temperature as they were in the 1930s. Also in particular the rate of global warming in the early 20th century was as great as the last third of the century, and no one seriously ascribes the early century increase to greenhouse gas emissions.

  2. Predictions of climate models are demonstrably too high, indicating a significant overestimate of the climate sensitivity (the response of the earth to increases in the incident radiation caused by atmospheric greenhouse gases). This is because the models, upon which the IPCC relies for their future projections, err in their calculations of key feedback and driving forces in the climate system.

  3. Natural effects have been and continue to be important contributors to variations in the earth’s climate, especially solar variability and decadal and multidecadal ocean cycles.

  4. The recorded land-based temperature increase data are significantly exaggerated due to widespread errors in data gathering and inadequately corrected contamination by human activity.

  5. The multitude of environmental and ecological effects blamed on climate change to date is either exaggerated or nonexistent. Examples are claims of more frequent and ferocious storms, accelerated melting of terrestrial icecaps, Mount Kilimanjaro’s glacier, polar bear populations, and expansive mosquito-borne diseases. All of these and many others have been claimed and ascribed to global warming and by extension to human activity, and all are bogus or highly exaggerated.

I would be pleased to provide details on any of these five key reasons. Many others can do so as well.

And here is the full paper by Cohen, with figures and footnotes [PDF].

As regular readers of The Kitchen will know, the idea that the "recorded land-based temperature increase data are significantly exaggerated due to widespread errors in data gathering and inadequately corrected contamination by human activity" is a pretty mild way of putting it. I would say that it has been deliberately falsified or simply made up.

So, how do we get all of this into the public consciousness? It's a difficult one because our state broadcaster, as the Ecclesiastical Eminence has highlighted, has abandoned impartiality on the issue.
The Harmless Sky blog has discovered that support for the catastrophic global warming case is official BBC policy. Tony quotes a BBC report as follows:
The BBC has held a high-level seminar with some of the best scientific experts, and has come to the view that the weight of evidence no longer justifies equal space being given to the opponents of the consensus [on anthropogenic climate change].

The details of the seminar are, as one might expect from an organisation like the BBC which holds the public in such contempt, a secret. An FoI request has revealed that uber-warmer, Lord May, was the driver behind the decision, but the rest of the details are only going to be revealed if the Information Commissioner can force them to toe the line.

And, as Bishop Hill also notes, this wasn't the story only a little while ago.
Interesting also to remind ourselves that as recently as a year ago, the head of BBC news was claiming that the Corporation had no line on climate change.

So, our taxpayer-funded, state-mandated BBC has decided to endorse the government's line and embrace the liars: who would'a thunk it?

And in the meantime, all that we climate sceptics can do is to keep collating and posting the evidence and try to show as many people as possible that they are being deceived by the AGW alarmists...

Up to 2003 or so, we were bombarded with headlines each summer saying "This is the hottest summer ever". This summer has been demonstrably and verifiably fucking piss poor and chilly, but has anybody seen a headline saying "This summer was a bloody sight colder than a few years ago"?


I thought not.

Back in 2005 and 2006 the British Broadcasting Communists bleated on and on how the south-east of England was parched dry, the reservoirs were at a critical level and how this was all the result of global warming, etc, etc,
The Autumn and Winter of 2006/2007 were ‘wet’ to put it mildly and reservoir levels were replenished by mid November across the south-east, did they follow up their incessant bleating of ‘oh no we’re all going to die in a dust ball without any water supplies’,, thought not, like all good bullshit merchants they moved onto the next tenuous piece of ‘evidence’ of global warming they could lay their paws on.

Take a look at Wildfire risk to tinder-dry rural Britain as a marvelous example of the problems wearysider is referring to.

Will you everyone please, PLEASE, get rid of your TVs and stop paying the BBC with your cash. It's not difficult, you won't miss it (play more DVDs on your PC) and you can do it now - no organisation necessary.

We should put the cricket authorities in charge of weather forecasting. This week the final test match of the summer ended, many weeks earlier than usual. They must have known August was going to be shyte.
