Quick note before we begin:
There was another thread on this issue previously, it was started by manami but it got shut down by frags because the discussion started going into topics relating to "the new world order" and other topics relating to how "the elite are trying to impose controls on people", where these topics were deemed as conspiracy theories by frags.

I'm not saying that I agree that those topics are conspiracy theories nor am I saying that they aren't conspiracy theories, but for the purposes of this thread let's try to maintain some level-headedness and stay on topic with the issues and consequences surrounding climategate. Also if or when the discussion about Carbon Taxes or Carbon Credits arise, it would again be prudent to discuss any positive or negative issues surrounding them without invoking spin-off discussions such as a global movement by those with power to impose controls over people and industry. Doing so will bring about protracted discussions on the validity of such statements and pose a risk of derailing this topic.

So we begin.

The reason why even the Guardian's George Monbiot has expressed total shock and dismay at the picture revealed by the documents is that their authors are not just any old bunch of academics. Their importance cannot be overestimated, What we are looking at here is the small group of scientists who have for years been more influential in driving the worldwide alarm over global warming than any others, not least through the role they play at the heart of the UN's Intergovernmental Panel on Climate Change (IPCC).

Professor Philip Jones, the CRU's director, is in charge of the two key sets of data used by the IPCC to draw up its reports. Through its link to the Hadley Centre, part of the UK Met Office, which selects most of the IPCC's key scientific contributors, his global temperature record is the most important of the four sets of temperature data on which the IPCC and governments rely – not least for their predictions that the world will warm to catastrophic levels unless trillions of dollars are spent to avert it.

Dr Jones is also a key part of the closely knit group of American and British scientists responsible for promoting that picture of world temperatures conveyed by Michael Mann's "hockey stick" graph which 10 years ago turned climate history on its head by showing that, after 1,000 years of decline, global temperatures have recently shot up to their highest level in recorded history.

Since 2003, however, when the statistical methods used to create the "hockey stick" were first exposed as fundamentally flawed by an expert Canadian statistician Steve McIntyre , an increasingly heated battle has been raging between Mann's supporters, calling themselves "the Hockey Team", and McIntyre and his own allies, as they have ever more devastatingly called into question the entire statistical basis on which the IPCC and CRU construct their case.

The senders and recipients of the leaked CRU emails constitute a cast list of the IPCC's scientific elite, including not just the "Hockey Team", such as Dr Mann himself, Dr Jones and his CRU colleague Keith Briffa, but Ben Santer, responsible for a highly controversial rewriting of key passages in the IPCC's 1995 report; Kevin Trenberth, who similarly controversially pushed the IPCC into scaremongering over hurricane activity; and Gavin Schmidt, right-hand man to Al Gore's ally Dr James Hansen, whose own GISS record of surface temperature data is second in importance only to that of the CRU itself.

This in itself has become a major scandal, not least Dr Jones's refusal to release the basic data from which the CRU derives its hugely influential temperature record, which culminated last summer in his startling claim that much of the data from all over the world had simply got "lost". Most incriminating of all are the emails in which scientists are advised to delete large chunks of data, which, when this is done after receipt of a freedom of information request, is a criminal offence.

In each of these countries (Australia and New Zealand) it has been possible for local scientists to compare the official temperature record with the original data on which it was supposedly based. In each case it is clear that the same trick has been played – to turn an essentially flat temperature chart into a graph which shows temperatures steadily rising. And in each case this manipulation was carried out under the influence of the CRU.

The third shocking revelation of these documents is the ruthless way in which these academics have been determined to silence any expert questioning of the findings they have arrived at by such dubious methods – not just by refusing to disclose their basic data but by discrediting and freezing out any scientific journal which dares to publish their critics' work. It seems they are prepared to stop at nothing to stifle scientific debate in this way, not least by ensuring that no dissenting research should find its way into the pages of IPCC reports.

“It is well known within the scientific community and particularly those who are sceptical of climate change that over 95% of the raw station data has been accessible through the Global Historical Climatology Network for several years.  We are quite clearly not hiding information which seems to be the speculation on some blogs and by some media commentators,” commented the University’s Pro-Vice-Chancellor, Research Enterprise and Engagement Professor Trevor Davies.

The University will make all the data accessible as soon as they are released from a range of non-publication agreements.  Publication will be carried out in collaboration with the Met Office Hadley Centre.

The procedure for releasing these data, which are mainly owned by National Meteorological Services (NMSs) around the globe, is by direct contact between the permanent representatives of NMSs (in the UK the Met Office).

“We are grateful for the necessary support of the Met Office in requesting the permissions for releasing the information but understand that responses may take several months and that some countries may refuse permission due to the economic value of the data,” continued Professor Davies.

The remaining data, to be published when permissions are given, generally cover areas of the world where there are fewer data collection stations.

“CRU’s full data will be published in the interests of research transparency when we have the necessary agreements. It is worth reiterating that our conclusions correlate well to those of other scientists based on the separate data sets held by the National Oceanic and Atmospheric Administration (NOAA) and the NASA Goddard Institute for Space Studies (GISS),” concluded Professor Davies.

SCIENTISTS at the University of East Anglia (UEA) have admitted throwing away much of the raw temperature data on which their predictions of global warming are based.

It means that other academics are not able to check basic calculations said to show a long-term rise in temperature over the past 150 years.

The UEA’s Climatic Research Unit (CRU) was forced to reveal the loss following requests for the data under Freedom of Information legislation.

Jones was not in charge of the CRU when the data were thrown away in the 1980s, a time when climate change was seen as a less pressing issue. The lost material was used to build the databases that have been his life’s work, showing how the world has warmed by 0.8C over the past 157 years.

Since 2003, however, when the statistical methods used to create the "hockey stick" were first exposed as fundamentally flawed by an expert Canadian statistician Steve McIntyre , an increasingly heated battle has been raging between Mann's supporters, calling themselves "the Hockey Team", and McIntyre and his own allies, as they have ever more devastatingly called into question the entire statistical basis on which the IPCC and CRU construct their case.

'A common exercise in any intro statistic class is to split the students into two groups, one group flips a coin 100 times and records the results, another just makes 100 entries up off the top of their heads. The teacher then comes back, looks at the two lists, and usually identifies which is which with hardly a glance. How? The trick is the teacher knows that on the real list, there will be several sequences of four or five in a row of all heads or all tails, whereas on the other list students will tend to stick with a more heads-tails-heads-tails alternating approach.

Now, everyone knew what I meant just now when I wrote trick, right? Nothing deceitful, simply the method used to get an answer to a math problem. With that in mind, let's look at this 1999 email purporting to be evidence of fraud among some climate scientists:

"I've just completed Mike's Nature trick of adding in the real temps to each series for the last 20 years (i.e., from 1981 onwards) and from 1961 for Keith's to hide the decline."

The email is one of thousands sent over a period of ten years by climate researchers and other scientists, journalists, lobbyists, and the occasional flake, stolen from a university network a few days ago. DeSmogBlog has more on the theft. Obviously, emails don't change the observed reality of human assisted climate change in the cryosphere and elsewhere. Nevertheless, climate change denialists have combed through them looking for anything they can pull out of context and pass off as evidence of a global conspiracy. They're getting some media mileage out of it. Even though, so far, the best they've been able to come up with is examples like the above.

The "Mike" is Michael Mann, "hide" means to account for (See also this comment), and the trick referred to is how to resolve a question involving two sets of data. One set is the "real" actual temperature readings, the other is by proxy, tree-rings, corals, ice cores and the like. When reconstructing the temperature record going back a thousand years or more, proxies are all you get -- there were no super accurate thermometers handily placed around the globe during medieval times! But proxies only give an approximation, hence the large variance in the now familiar reconstruction graph affectionately known as the Hockey Stick represented below as shading around the blue and red lines.'

Climategate and the recent IPCC conference in Denmark highlighted some major points - that there isn't a uniform consensus on AGW, and that the developed nations are using this as an excuse to strangle the developing nations by using fear-mongering to subdue less-developed nations.

Carbon-capping will prevent the industrialization of the less-developed nations. Carbon taxes, carbon trading etc. will some day be just like energy futures and become something that's market-driven rather than being based on real science.

Somehow, there are humans who are so stupid as to think that puny humans can change the world's climate with our doing, when a majority of the planet's surface in terms of volume and area are the oceans (which has hardly any human presence). A single volcano eruption is more powerful than a 1000 hiroshima nukes. A single underwater earthquake is more energetic than a few hundred thousand of the world's most powerful nuclear warheads.

And we think our industrialization will bring about the end of the world?

Our industrialization did bring about changes to the environment but when the Earth's climate changes naturally, it'll be much more than what humans are capable of. Look at the 70s, when there was a global cooling and everyone's afraid of a new "Little Ice Age". From WW2 until the 70s, for more than 3 decades, we were on a crazy industrialization drive.

How do we also explain the fact that the atmospheres of Mars, Jupiter and Saturn recorded an average increase of 0.5 degrees in the past 20 years or so? Human colonies spewing CO2 and greenhouse gases into their atmospheres?

so what is the real motive behind the scandal?
