UN on Climategate: Uhhhhhh

The UN has apparently had something to say about the growing scandal about global warming data. Leaks have placed great doubt on the scientific "consensus" that unchecked, global warming will kill us all.

Even though leaked emails have shown that even many of the environmental scientists are fudging the numbers about warming, thew UN won't take them into account.

But of course, there won't be bias because of peer review. Peer review is an excellent tool to weed out incompetence, unless of course, everyone agrees on something:

Pachauri said the large number of contributors and rigorous peer review mechanism adopted by the IPCC meant that any bias would be rapidly uncovered.

"The processes in the IPCC are so robust, so inclusive, that even if an author or two has a particular bias it is completely unlikely that bias will find its way into the IPCC report," he said.

Well, that's reassuring.

The "Global Warning Hoax"

With the release of formerly secret documents from a global warming thinktank, accusations of a great global warming fraud are permeating the internets. Take a look:

CBS News:

A few days after leaked e-mail messages appeared on the Internet, the U.S. Congress may probe whether prominent scientists who are advocates of global warming theories misrepresented the truth about climate change.

Sen. James Inhofe, an Oklahoma Republican, said on Monday the leaked correspondence suggested researchers "cooked the science to make this thing look as if the science was settled, when all the time of course we knew it was not," according to a transcript of a radio interview posted on his Web site. Aides for Rep. Darrell Issa, a California Republican, are also looking into the disclosure.

The leaked documents (see our previous coverage) come from the Climatic Research Unit of the University of East Anglia in eastern England. In global warming circles, the CRU wields outsize influence: it claims the world's largest temperature data set, and its work and mathematical models were incorporated into the United Nations Intergovernmental Panel on Climate Change's 2007 report. That report, in turn, is what the Environmental Protection Agency acknowledged it "relies on most heavily" when concluding that carbon dioxide emissions endanger public health and should be regulated.

Last week's leaked e-mails range from innocuous to embarrassing and, critics believe, scandalous. They show that some of the field's most prominent scientists were so wedded to theories of man-made global warming that they ridiculed dissenters who asked for copies of their data ("have to respond to more crap criticisms from the idiots"), cheered the deaths of skeptical journalists, and plotted how to keep researchers who reached different conclusions from publishing in peer-reviewed journals.

One e-mail message, apparently from CRU director Phil Jones, references the U.K.'s Freedom of Information Act when asking another researcher to delete correspondence that might be disclosed in response to public records law: "Can you delete any emails you may have had with Keith re AR4? Keith will do likewise." Another, also apparently from Jones: global warming skeptics "have been after the CRU station data for years. If they ever hear there is a Freedom of Information Act now in the UK, I think I'll delete the file rather than send to anyone." (Jones was a contributing author to the chapter of the U.N.'s IPCC report titled "Detection of Climate Change and Attribution of Causes.")

In addition to e-mail messages, the roughly 3,600 leaked documents posted on sites including Wikileaks.org and EastAngliaEmails.com include computer code and a description of how an unfortunate programmer named "Harry" -- possibly the CRU's Ian "Harry" Harris -- was tasked with resuscitating and updating a key temperature database that proved to be problematic. Some excerpts from what appear to be his notes, emphasis added:
I am seriously worried that our flagship gridded data product is produced by Delaunay triangulation - apparently linear as well. As far as I can see, this renders the station counts totally meaningless. It also means that we cannot say exactly how the gridded data is arrived at from a statistical perspective - since we're using an off-the-shelf product that isn't documented sufficiently to say that. Why this wasn't coded up in Fortran I don't know - time pressures perhaps? Was too much effort expended on homogenisation, that there wasn't enough time to write a gridding procedure? Of course, it's too late for me to fix it too. Meh.

I am very sorry to report that the rest of the databases seem to be in nearly as poor a state as Australia was. There are hundreds if not thousands of pairs of dummy stations, one with no WMO and one with, usually overlapping and with the same station name and very similar coordinates. I know it could be old and new stations, but why such large overlaps if that's the case? Aarrggghhh! There truly is no end in sight... So, we can have a proper result, but only by including a load of garbage!

One thing that's unsettling is that many of the assigned WMo codes for Canadian stations do not return any hits with a web search. Usually the country's met office, or at least the Weather Underground, show up – but for these stations, nothing at all. Makes me wonder if these are long-discontinued, or were even invented somewhere other than Canada!

Knowing how long it takes to debug this suite - the experiment endeth here. The option (like all the anomdtb options) is totally undocumented so we'll never know what we lost. 22. Right, time to stop pussyfooting around the niceties of Tim's labyrinthine software suites - let's have a go at producing CRU TS 3.0! since failing to do that will be the definitive failure of the entire project.

Ulp! I am seriously close to giving up, again. The history of this is so complex that I can't get far enough into it before by head hurts and I have to stop. Each parameter has a tortuous history of manual and semi-automated interventions that I simply cannot just go back to early versions and run the update prog. I could be throwing away all kinds of corrections - to lat/lons, to WMOs (yes!), and more. So what the hell can I do about all these duplicate stations?...

As the leaked messages, and especially the HARRY_READ_ME.txt file, found their way around technical circles, two things happened: first, programmers unaffiliated with East Anglia started taking a close look at the quality of the CRU's code, and second, they began to feel sympathetic for anyone who had to spend three years (including working weekends) trying to make sense of code that appeared to be undocumented and buggy, while representing the core of CRU's climate model.

One programmer highlighted the error of relying on computer code that, if it generates an error message, continues as if nothing untoward ever occurred. Another debugged the code by pointing out why the output of a calculation that should always generate a positive number was incorrectly generating a negative one. A third concluded: "I feel for this guy. He's obviously spent years trying to get data from undocumented and completely messy sources."

Programmer-written comments inserted into CRU's Fortran code have drawn fire as well. The file briffa_sep98_d.pro says: "Apply a VERY ARTIFICAL correction for decline!!" and "APPLY ARTIFICIAL CORRECTION." Another, quantify_tsdcal.pro, says: "Low pass filtering at century and longer time scales never gets rid of the trend - so eventually I start to scale down the 120-yr low pass time series to mimic the effect of removing/adding longer time scales!"

It's not clear how the files were leaked. One theory says that a malicious hacker slipped into East Anglia's network and snatched thousands of documents. Another says that the files had already been assembled in response to a Freedom of Information request and, immediately after it was denied, a whistleblower decided to disclose them. (Lending credence to that theory is the fact that no personal e-mail messages unrelated to climate change appear to have been leaked.)

For its part, the University of East Anglia has posted a statement calling the disclosure "mischievous" and saying it is aiding the police in an investigation.

The statement also quotes Jones, CRU's director, explaining his November 1999 e-mail, which said: "I've just completed Mike's Nature trick of adding in the real temps to each series for the last 20 years (ie from 1981 onwards) amd from 1961 for Keith's to hide the decline." Jones said that the word trick was used "colloquially as in a clever thing to do" and that it "is ludicrous to suggest that it refers to anything untoward."

Also unclear is the ultimate impact of the leak, which came before next month's Copenhagen summit and Democratic plans for cap and trade legislation.

On one hand, over at RealClimate.org, Gavin Schmidt, a modeler for the NASA Goddard Institute for Space Studies, has been downplaying the leak. Schmidt wrote: "There is no evidence of any worldwide conspiracy, no mention of George Soros nefariously funding climate research ... no admission that global warming is a hoax, no evidence of the falsifying of data, and no 'marching orders' from our socialist/communist/vegetarian overlords."

On the other, groups like the free-market Competitive Enterprise Institute, the target of repeated derision in the leaked e-mails, have said: "We have argued for many years that much of the scientific case for global warming alarmism was weak and some of it was phony. It now looks like a lot of it may be phony."

ScienceMag.org published an article noting that deleting e-mail messages to hide them from a FOI request is a crime in the United Kingdom. George Monbiot, a U.K. activist and journalist who previously called for dramatic action to deal with global warming, wrote: "It's no use pretending that this isn't a major blow. The emails extracted by a hacker from the climatic research unit at the University of East Anglia could scarcely be more damaging."

Complicating matters for congressional Republicans who'd like to hold hearings is that East Anglia, of course, is a U.K. university. The GOP may intend to press the Obama administration for details on how the EPA came to rely on the CRU's predictions, and whether the recent disclosure will change the agency's position. Another approach lies in e-mail messages discussing grants from the U.S. Commerce Department's National Oceanic and Atmospheric Administration to East Anglia; one says: "We need to show some left to cover the costs of the trip Roger didn't make and also the fees/equipment/computer money we haven't spent otherwise NOAA will be suspicious."

The irony of this situation is that most of us expect science to be conducted in the open, without unpublished secret data, hidden agendas, and computer programs of dubious reliability. East Anglia's Climatic Research Unit might have avoided this snafu by publicly disclosing as much as possible at every step of the way.

Gallup: 41% Say Global Warming "Exaggerated"

An increasing amount of Americans are skeptical of all of the talk about global warming. While I may personally believe it may be happening, all of the hooplah is out of control, with Al Gore more in love with Al Gore than Miami-Dade county in November 2000.

As recently as 2006, significantly more Americans thought the news underestimated the seriousness of global warming than said it exaggerated it, 38% vs. 30%. Now, according to Gallup's 2009 Environment survey, more Americans say the problem is exaggerated rather than underestimated, 41% vs. 28%.

The trend in the "exaggerated" response has been somewhat volatile since 2001, and the previous high point, 38%, came in 2004. Over the next two years, "exaggerated" sentiment fell to 31% and 30%. Still, as noted, the current 41% is the highest since Gallup's trend on this measure began in 1997.

Global Warming might be on hold, study finds

From MSNBC (of all places):

"For those who have endured this winter's frigid temperatures and today's heavy snowstorm in the Northeast, the concept of global warming may seem, well, almost wishful.

But climate is known to be variable — a cold winter, or a few strung together doesn't mean the planet is cooling. Still, according to a new study, global warming may have hit a speed bump and could go into hiding for decades.

Earth's climate continues to confound scientists. Following a 30-year trend of warming, global temperatures have flatlined since 2001 despite rising greenhouse gas concentrations, and a heat surplus that should have cranked up the planetary thermostat.

"This is nothing like anything we've seen since 1950," Kyle Swanson of the University of Wisconsin-Milwaukee said. "Cooling events since then had firm causes, like eruptions or large-magnitude La Ninas. This current cooling doesn't have one."

Instead, Swanson and colleague Anastasios Tsonis think a series of climate processes have aligned, conspiring to chill the climate. In 1997 and 1998, the tropical Pacific Ocean warmed rapidly in what Swanson called a "super El Nino event." It sent a shock wave through the oceans and atmosphere, jarring their circulation patterns into unison.

How does this square with temperature records from 2005-2007, by some measurements among the warmest years on record? When added up with the other four years since 2001, Swanson said the overall trend is flat, even though temperatures should have gone up by 0.2 degrees Centigrade (0.36 degrees Fahrenheit) during that time.

The discrepancy gets to the heart of one of the toughest problems in climate science — identifying the difference between natural variability (like the occasional March snow storm) from human-induced change.

But just what's causing the cooling is a mystery. Sinking water currents in the north Atlantic Ocean could be sucking heat down into the depths. Or an overabundance of tropical clouds may be reflecting more of the sun's energy than usual back out into space.

"It is possible that a fraction of the most recent rapid warming since the 1970's was due to a free variation in climate," Isaac Held of the National Oceanic and Atmospheric Administration in Princeton, New Jersey wrote in an email to Discovery News. "Suggesting that the warming might possibly slow down or even stagnate for a few years before rapid warming commences again."

Swanson thinks the trend could continue for up to 30 years. But he warned that it's just a hiccup, and that humans' penchant for spewing greenhouse gases will certainly come back to haunt us.

"When the climate kicks back out of this state, we'll have explosive warming," Swanson said. "Thirty years of greenhouse gas radiative forcing will still be there and then bang, the warming will return and be very aggressive.""
