Margaret Thatcher was the first leader to warn of global warming - but also the first to see the flaws in the climate change orthodoxy A persistent claim made by believers in man-made global warming – they were at it again last week – is that no politician was more influential in launching the worldwide alarm over climate change than Margaret Thatcher. David Cameron, so the argument runs, is simply following in her footsteps by committing the Tory party to its present belief in the dangers of global warming, and thus showing himself in this respect, if few others, to...

Gavin Schmidt’s time spent on editing realclimate.org during working hours apparently was the trigger for a broader investigation.FOR IMMEDIATE RELEASE Tuesday, June 21, 2011 Contacts: Christopher Horner, chris.horner@atinstitute.org  Paul Chesser, paul.chesser@atinstitute.orgATI Law Center Asks Court to Force NASA to Produce Ethics-Related, Outside Employment Records of Dr. James Hansen The American Tradition Institute’s Environmental Law Center today filed a lawsuit in federal district court in the District of Columbia to force the National Aeronautics and Space Administration (NASA) to release ethics records for taxpayer-funded global warming activist Dr. James Hansen, specifically records that pertain to his outside employment, revenue generation, and...

Two years before the Fourth Assessment Report of the Intergovernmental Panel on Climate Change was released in 2007, this comment about an early draft of the report came in from Andrew Lacis, a physicist at the Goddard Institute for Space Studies, the NASA lab led for decades by the "godfather" of the global warming hoax, Dr. James Hansen: There is no scientific merit to be found in the Executive Summary. The presentation sounds like something put together by Greenpeace activists and their legal department. The points being made are made arbitrarily with legal sounding caveats without having established any...

NEW YORK -- Water vapor and clouds are the major contributors to Earth's greenhouse effect, but a new atmosphere-ocean climate modeling study shows that the planet's temperature ultimately depends on the atmospheric level of carbon dioxide. The study, conducted by Andrew Lacis and colleagues at NASA's Goddard Institute for Space Studies (GISS) in New York, examined the nature of Earth's greenhouse effect and clarified the role that greenhouse gases and clouds play in absorbing outgoing infrared radiation. Notably, the team identified non-condensing greenhouse gases -- such as carbon dioxide, methane, nitrous oxide, ozone, and chlorofluorocarbons -- as providing the core...

Oct. 15) -- The Earth's atmosphere is a complicated place. Somewhere in that swirling, shifting mixture of air, water and other gasses is the key to keeping us earthlings alive -- or to cooking us. Carbon dioxide has always received the most media attention as the leading cause of climate change, and a new study from NASA does more than concur with this assessment: It finds CO2 is overwhelmingly responsible for raising Earth's temperature.

(Source: global-greenhouse-warming.com) Water vapor and clouds cannot sustain the greenhouse effect on their own Researchers at NASA's Goddard Institute for Space Studies (GISS) have concluded, through the use of a new atmosphere-ocean climate model, that carbon dioxide manipulates Earth's temperature.  Andrew Lacis of the GISS, along with David Rind and other colleagues, studied the Earth's greenhouse effect, and has concluded that non-condensing greenhouse gases such as carbon dioxide, ozone, chlorofluorocarbons, nitrous oxide and methane play central roles in the greenhouse effect.  While water vapor and clouds are the major players when it comes to Earth's greenhouse effect, Lacis and his colleagues...

Email messages obtained by the Competitive Enterprise Institute via a Freedom of Information Act request reveal that the climate dataset of NASA’s Goddard Institute for Space Studies (GISS) was considered — by the top climate scientists within NASA itself — to be inferior to the data maintained by the University of East Anglia Climate Research Unit (CRU). The NASA scientists also felt that NASA GISS data was inferior to the National Climate Data Center Global Historical Climate Network (NCDC GHCN) database. These emails, obtained by Christopher Horner, also show that the NASA GISS dataset was not independent of CRU data....

I am proud to add Dr. Jan Zeman’s authoritative addendum to substantiate the claims made in my Czechgate article. With Dr. Zeman’s permission I have edited and revised his paper slightly for publication. THE KLEMENTINUM RECORD – UHI AND LOCAL WARMING by Jan Zeman The “global warming agencies” literally raped the data from Prague Klementinum. On the graph we see the data from GISS although the NOAA and CRU versions are very similar. What has been stripped out from the record is the most valuable part going from the 1770’s to the latter half of the 19th century. Thereafter, it...

In this article we look at the findings of two independent climate researchers who analyse climatic data used by the Intergovernmental Panel on Climate Change (IPCC) to show warming of two degrees per century for Australia without explanation. We find that an earlier study by Willis Eschenbach in an article on What’s up with That (WUWT) is wholly substantiated by Kens Kingdom’slatest analysis of Ken Stewart at his ‘kenskingdom’ blog. As a consequence, absent any other justification from NASA, we must conclude that the NASA data has been fraudulently cooked. GISS, based at Columbia University in New York City, has...

While perusing some of the review comments to the IPCC’s Fourth Assessment Report, I came across the contributions of Andrew Lacis, a colleague of James Hansen’s at GISS. Lacis’s is not a name I’ve come across before but some of what he has to say about Chapter 9 of the IPCC’s report is simply breathtaking. Chapter 9 is possibly the most important one in the whole IPCC report – it’s the one where they decide that global warming is manmade. This is the one where the headlines are made. Remember, this guy is mainstream, not a sceptic, and you may...

Hoaxes: Climate researchers and the Weather Channel's founder accuse NASA of the same data manipulation as Britain's Climate Research Unit. Were weather stations cherry-picked to hide the temperature drop? We recently commented on how our space agency for two years refused Freedom of Information requests on why it has had to repeatedly correct its climate figures. In a report on global warming on KUSI television by Weather Channel founder and iconic TV weatherman John Coleman, that reticence has been traced to the deliberate manipulation and distortion of climate data by NASA. As Coleman noted in a KUSI press release, NASA's...

For those who haven’t seen it, here’s a link to US weatherman John Coleman’s magisterial demolition of the Great AGW Scam. I particularly recommend part 4 because that’s the one with all the meat. It shows how temperature readings have been manipulated at the two key climate data centres in the United States – the NASA Goddard Science and Space Institute at Columbia University in New York and the NOAA National Climate Data Center in Ashville, North Carolina. (Hat tip: Platosays) This is a scandal to rank with Climategate. What it shows is that, just like in Britain at the...

Has Climategate moved to the US? Looks like it from this story at Watts Up With That. (Hat tip: R. Campbell) It reports: Judicial Watch, the public interest group that investigates and prosecutes government corruption, announced today that it has obtained internal documents from NASA’s Goddard Institute for Space Studies (GISS) related to a controversy that erupted in 2007 when Canadian blogger Stephen McIntyre exposed an error in NASA’s handling of raw temperature data from 2000-2006 that exaggerated the reported rise in temperature readings in the United States. According to multiple press reports, when NASA corrected the error, the new...

Science: For two years, our space agency has refused Freedom of Information requests on why it has repeatedly corrected its climate figures. A leading researcher threatens to sue to find more inconvenient truths. What's become known as "Climate-Gate" may be about to explode on this side of the pond as well. Chris Horner, a senior fellow at the Competitive Enterprise Institute, has threatened a lawsuit against NASA if by year-end the agency doesn't honor his FOI requests for information on how and why its climate numbers have been consistently adjusted for errors. "I assume that what is there is highly...

Nasa's James Hansen was the first to point out the perils of climate change to the US Congress. Here, he begins a heated debate with experts from around the world, from China to the threatened Maldives, and argues that our leaders must be shaken out of their complacency. But will they show enough courage at next week's Copenhagen summit to take the first steps to saving the planet?Absolutely. It is possible – if we give politicians a cold, hard slap in the face. The fraudulence of the Copenhagen approach – "goals" for emission reductions, "offsets" that render ironclad goals almost...

A leading scientist acclaimed as the grandfather of global warming has denounced the Copenhagen summit on climate change next week as a farce. James Hansen, the director of Nasa’s Goddard Insitute for Space Studies, told The Times that he planned to boycott the UN conference because it was seeking a counter-productive agreement to limit emissions through a “cap and trade” system. “They are selling indulgences there. The developed nations want to continue basically business as usual so they are expected to purchase indulgences to give some small amount of money to developing countries. They do that in the form of...

In particular, a few computers at NASA's Goddard Institute seem to be having a disproportionate effect on global warming. Anthony Watt takes a cut at an analysis I have tried myself several times, comparing raw USHCN temperature data to the final adjusted values delivered from that data by the NASA computers. My attempt at this compared the USHCN adjusted to raw for the entire US: Anthony Watt does this analysis from USHCN raw all the way through to the GISS adjusted number (the USHCN adjusts the number, and then the GISS adds their own adjustments on top of these adjustments)....

Previously (A Tale of Two Thermometers) we looked at how US temperature data sets have been adjusted - with more recent versions of historical data sets showing a steeper rise in temperature than they used to. To recap the earlier article, the graph below shows additional adjustments to the data set since the big "correction" in 2000 We observe that the data has been consistently adjusted towards a bias of greater warming. The years prior to the 1970s have again been adjusted to lower temperatures, and recent years have been adjusted towards higher temperatures. DivergenceSo how does NASA's data compare...

In the “good old days” (August 25, 2007: after they had corrected their Y2K error), I downloaded Hansen’s “combined” version (his dset=1).

Its interesting how NASA has been able to justify keeping their codes "top secret" in relation to "climate change" and Glo-bull Warm-ing

I've been thinking about my criticism of a U.S. National Aeronautics and Space Administration (NASA) study of tornadoes and hail in the previous post. I realize now that I was far too leniet on those who conducted the study. The study should never have been funded. It should never have passed the peer review process and it should never have been pubished in any scientific journal. The authors apparently are ignorant of the fact temperatures in most of the U.S. change drastically over a year's time. Seasonal changes are particularly drastic in "tornado alley" in the central U.S.. A mere...

Hansen Frees the Code By Steve McIntyre Hansen has just released what is said to be the source code for their temperature analysis. The release was announced in a shall-we-say ungracious email to his email distribution list and a link is now present at the NASA webpage. Hansen says resentfully that they would have liked a “week or two” to make a “simplified version” of the program and that it is this version that “people interested in science” will want, as opposed to the version that actually generated their results.

Steve McIntyre says: September 4th, 2007 at 6:08 pm I’ve posted an update to the post, setting out what I believe to be the most plausible answers. Thanks to everyone who participated and particularly to John Goetz for framing the problem and then solving the calculation of the delta. The next puzzle, as John G articulated, is to figure out how Hansen calculated seasonal and annual averages when there is missing data. However, even without solving this puzzle, the present evidence is sufficient to establish that Hansen’s method of combining different scribal versions is erroneous and has corrupted his entire...

Was 1998 the hottest year in United States history, as most reporting on climate change has presumed? Or was that record set back in 1934 before "global warming" became a scary household phrase? A corrective tweak to National Aeronautics and Space Administration's formulation shows that the hottest year on record in the United States indeed was back during the Dust Bowl days. But does this mean that all the concern about global warming being a relatively recent phenomenon tied to carbon-belching power plants and hulking SUVs is a bunch of Al Gore hooey? Climate change skeptics and their cheering section...

James Hansen, NASA's True Believer in the global warming credo, has just been quoted by the Globe & Mail of Canada as follows: "Prof. Hansen and his colleagues argue that rapidly melting ice caps in Antarctica and Greenland could cause oceans to swell several metres by 2100 - or maybe even as much as 25 metres, which is how much higher the oceans sat about three million years ago." In an email to the Globe and Mail, Hansen writes "If we follow 'business-as-usual' growth of greenhouse gas emissions... I think that we will lock in a guaranteed sea-level rise of...

I believe that most here are now aware of the NASA GISS temperature data that was corrected by a Canadian researcher, Steven McIntyre, now shows the hottest year in the USA is not 1998, but rather the year 1934. This post is just to point out two things: 1) the order of the hottest years and 2) the media coverage of this hugely important data correction to US yearly temperatures. From the corrected data posted by NASA, it now shows the correct hottest years as follows, beginning with hottest:http://data.giss.nasa.gov/gistemp/graphs/Fig.D.txt 1934 1998 1921 2006 1931 1999 1953 1990 1938 1939 1954...

Some alarming global-warming data reconsidered. While Americans were being stampeded at great cost and inconvenience into combating the presumed horrors of manmade global warming – be it in Newsweek or by the California Attorney General's Office – some news largely went unnoticed last week. Instead of 1998 being the "hottest year" since 1880 in the continental United States, as some global warming alarmists claimed, it turns out that 1934 was. Instead of nine of the 10 hottest years since 1880 occurring after 1995, it turns out that four of the hottest years were in the 1930s, and the third-hottest was...

... Last week, Hansen, NASA's lead scientist on global warming, penned a rather strange ad hominem attack against critics that questioned the validity of his work in the wake of corrections prompted by Steve McIntyre at Climate Audit http://www.climateaudit.org/ Under most circumstances, it is inappropriate for a Federal Agency Administrator to pen such a highly policitical polemic, although Hansen has a long history of doing just that. Rather than respond with a proper full acknowledgement of his error and a promise to uncover other potential flaws which may be lurking in his data and analyis, his technical explanation is interspersed...

In retrospect, you knew there would be trouble when you put the people responsible for the Space Shuttle program in charge of tracking U.S. temperatures. So perhaps it shouldn’t have come as a big surprise when it was revealed that NASA committed a bit of an oopsie regarding data constantly used by the mainstream media and other global warming proponents.

Agency roasted after Toronto blogger spots `hot years' data fumble In the United States, the calendar year 1998 ranked as the hottest of them all – until someone checked the math. After a Toronto skeptic tipped NASA this month to one flaw in its climate calculations, the U.S. agency ordered a full data review. Days later, it put out a revised list of all-time hottest years. The Dust Bowl year of 1934 now ranks as hottest ever in the U.S. – not 1998. More significantly, the agency reduced the mean U.S. "temperature anomalies" for the years 2000 to 2006 by...

.... "I object to the fact that I’m not able to freely communicate via the media," says Hansen. "National Public Radio wanted to interview me and they were told they would need to interview someone at NASA headquarters and the comment was made that they didn’t want Jim Hansen going on the most liberal media in America. So I don’t think that kind of decision should be made on that kind of basis. I think we should be able to communicate the science." Politically, Hansen calls himself an independent and he’s had trouble with both parties. He says, from time...

I've done some digging into the recent scandal over how GISS has quietly changed its data to reflect the fact that 1998 is no longer the warmest year on American record. However, thanks to the resources of the Wayback Machine of WebArchive, I've discovered that the 1998 data has not been quite so high for a while. This is the Wayback Machine archive of GISS's data page, home to the climate data that's been the subject of the recent controversy. Let's recall that the newly reevaluted figures are as follows:Contiguous 48 U.S. Surface Air Temperature Anomaly (C) ------------------------------------------------------ year Annual_Mean...

1998 was not the hottest US year ever.  Nor was 2006 the runner up. Sure, had you checked NASA's Goddard Institute for Space Studies (GISS) website just days ago, you would have thought so, but not today.  You see, thanks to the efforts of Steve McIntyre over at http://www.climateaudit.org/, the Surface Air Temperature Anomaly charts for those and many other years have been revised - predominately down. Why? It's a wild and technical story of compromised weather stations and hack computer algorithms (including, get this - a latent Y2K bug) and those wishing to read the fascinating details should follow...

A change in climate history data at NASA's Goddard Institute for Space Studies recently occurred which dramatically alters the debate over global warming. Yet, this transpired with no official announcement from GISS head James Hansen, and went unreported until Steve McIntyre of Climate Audit discovered it Wednesday. For some background, one of the key tenets of the global warming myth being advanced by Hansen and soon-to-be-Dr. Al Gore is that nine of the ten warmest years in history have occurred since 1995. McIntyre has been crunching the numbers used to determine such things as published by GISS, and has identified...

According to David Rind from NASA's Goddard Institute for Space Studies (GISS), 2005 is going to set the all-time record for global warmth. He told Juliet Eilperin of the Washington Post (October 13, 2005) only a major volcanic eruption could intervene. But Eilperin also interviewed Oregon State Climatologist George Taylor, who told her that Goddard's findings were "mighty preliminary." That's because there's more than one history of global temperature. Three receive the most citations. NASA's record begins in 1880, as does another history from the U.S. Department of Commerce, developed at the Department's National Climatic Data Center (NCDC). But the...
