Clearly the outdated policies of Franklin Delano Roosevelt, were ruination to this planet.   I wonder if Greenpeace will make one of those big paper mache heads of FDR and hold an anti-New Deal rally for having the "worst record" on global warming of any President.

Supratext:

Even Greenwire's getting this wrong.

The uncertainty in the annual temperature anomalies is at least 0.1 C, so it's never been scientists saying 1998 was the hottest or 1934 was the hottest.

In fact, the only peer-reviewed statement from Hansen's team was that 1934 was marginally warmer than 1998. From Hansen 2001 et al.:
The U.S. annual (January-December) mean temperature is slightly warmer in 1934 than in 1998 in the GISS analysis (Plate 6)... the difference between 1934 and 1998 mean temperatures is a few hundredths of a degree.

Later adjustments to normalize the US temperature record by GISS put 1998 a few hundredths of a degree above 1934, but they never trumpeted that, since it wasn't significant. And now it's been renormalized again to bring 1998 a few hundredths of a degree below 1934 again. Wow. What a news story.

What's remarkable is how every single right-winger and mainstream journalist on this story has repeated the claim that 1998 "has long been believed" to be the hottest year in the US.

And yet noone has provided any sources to back up that claim. Why? Because that claim was hardly, if ever, made.

Interview transcript

Interviewer
A blogger in Toronto has caused an international stir over climate change. Steven McIntyre discovered that some of the measurements used by NASA to track average annual temperatures in the US were, to put it bluntly - wrong. The leaps over the last few years have not been as dramatic as previously thought. Global Warming sceptics in America are delighted.
Steven McIntyre explained to me how he spotted NASA's mistakes.
McIntyre
I compared the input data that NASA was using for US temperature to the original data in that was archived at other sources. When I made those comparisons, I noticed that there was a sharp jump in 2004 mini-series and the jump was up to one degree centigrade for some stations in the US, it was a negative jump in other stations.
Interviewer
And this was because NASA had not adjusted their figures correctly, is that right?
McIntyre
What they had done is they used one version of  US data before 2000 and a different version after 2000. The version before 2000 had certain adjustments in it, the version after 2000 didn't have those adjustments in it.
Interviewer
And what sort of adjustments are we talking about?
McIntyre
At the level of an individual station, the jump could be as much as one degree centigrade. For the United States temperature history as a whole, the jump was about point one five degrees centigrade, which compares to a increase of about half a degree for the entire century, so relative to the reported US increase, it wasn't a small adjustment.
Interviewer
So the conclusion that you drew was essentially that the world, or America at least is not getting hotter at the rate that others had previously assumed.
McIntyre
When I examined the changes that NASA made to their yearly rankings after they corrected this error: four of the top ten warmest years were in the thirties, whereas only three of the of the top ten were in the last ten years.
Interviewer
So your conclusions is that the trend is till up, but not just quite as sharp as most people originally thought it was.
McIntyre
As to what trend exists in the US data, one would have to enquire very closely as to why the nineteen thirties were so warm, relative to the modern period. And one thing that people should keep in mind is that NASA adjusts the temperature and the adjustments can be almost as large as the effect that's being measured, so that the adjustments can be half a degree per century, where the observed warming is half a degree. What I think is necessary is that there should be very careful scrutiny of how temperatures are measured over time, how we know whether the nineteen thirties compared to the two thousands and here we run into the problem that many of the weather stations are not meeting World Meteorological Organisation Standards. For example, the station in the US with the highest increase: the sensor is located in a parking lot in Tucson and if you can picture a worse environment for having a unbiased temperature reading than having a sensor above asphalt in Tucson in the Summer day, it's hard for me to imagine.
Interviewer
Steven McIntyre, Thank-you very much.
