Anthropogenic global warming. Settled science, right? Apparently not so much. It is so unsettled, that NASA, NOAA and the British Met have to change data to get where they want to go…and they ain’t too forthcoming with the raw numbers…
John Hinderaker at Powerline posts something interesting – it appears that NASA and NOAA are fudgin’ the data:
NOAA and NASA used to acknowledge the urban heat island effect and try to correct for it, but that didn’t produce the sort of alarming temperature increases that warmists are looking for. This is how NOAA depicted US temperatures from 1880 to 1999, as posted on NASA’s web site in 1999; click to enlarge:
James Hansen, the head of NASA’s climate unit and one of the worst of the alarmists, said truthfully in 1999:
The U.S. has warmed during the past century, but the warming hardly exceeds year-to-year variability. Indeed, in the U.S. the warmest decade was the 1930s and the warmest year was 1934.
That didn’t get the warmists where they were trying to go, so they have now changed the data by eliminating or drastically reducing the urban heat island effect. NASA now shows very different data for the period 1880-1999 from what it published in 1999. This animated GIF shows how the alarmists changed their own data to create the false impression of a climate crisis:
You probably assume that NOAA and NASA have made their raw data available to independent researchers, along with explanations of the adjustments they have made. But no–those agencies have resisted Freedom of Information Act requests for the original, raw data. One of the most important things the new Congress can do is to force these government agencies to level with the American people and explain the manipulations to which they have been subjecting weather data for years.
The London Telegraph reports that it isn’t just the Yanks doing it, its the UK Meteorological Office, too:
Dr Benny Peiser and Dr David Whitehouse, of the Global Warming Policy Foundation (GWPF), have written to John Hirst, chief executive of the beleaguered Met Office, asking for an explanation of a press release issued by his organisation on January 20 and headed “2010 – a near record year”. This won headlines by claiming that last year was hotter than any other in the past decade.
When the two men examined the original data from which this claim was derived – compiled by the University of East Anglia’s Climatic Research Unit and the Met Office’s Hadley Centre – it clearly showed 2010 as having been cooler than 2005 (and 1998) and equal to 2003. It emerged that, for the purposes of the press release, the data had been significantly adjusted.
Comparing the actual data for each year, from 2001 to 2010, with that given in the press release shows that for four years the original figure has been adjusted downwards. Only for 2010 was the data revised upwards, by the largest adjustment of all, allowing the Met Office to claim that 2010 was the hottest year of the decade.
The world is in the best of hands…
