Cherry Picking is Easy

Tamino has named me “Mr. Cherry” for picking start dates of graphs which are different from the ones he chooses to cherry pick. For instance, he considers 1975 to be the start of “the modern global warming era.”
Living up to his high standards, I declare August 16, 2010 to be the start of “the 2010 La Niña cool down”. Since August 16, UAH channel 5 global temperatures have been dropping at a rate of 1,554 degrees per century.
See below how that plots out.
If the trend continues, the earth will reach absolute zero in about 15 years.
That’s ridiculous, of course.
But the demonstration above is based on a similar logic of picking a start date of 1975 for measuring the global temperature record.
Why pick 1975? It makes the best pie.
Scientists Speak Out on Satellitegate Scandal

US Government admits global warming satellite sensors “degraded” – temperatures may be out by 10-15 degrees. Now five satellites in controversy. Top scientists speak out.
In an escalating row dubbed ‘Satellitegate’ further evidence proves NOAA knew of these faults for years. World’s top climate scientists and even prior governmental reports cite underfunding and misallocation as the trigger for spiraling satellite data calamities. Key flaws with five satellites undermines global data.
Most disturbing of all is that it took publication of my article last week to persuade the authorities to withdraw the errant NOAA-16 satellite from service. But as Dr. John Christy indicates, the real Satellitegate is not about one satellite. The scandal is endemic with comparable flaws across the entire network; the scandal is also that it took a tip off from a member of the public and the widespread broadcast of my article before one of the offending junk boxes, NOAA-16, got taken down.

EDITORIAL: More errors in temperature data

Yvo de Boer, the United Nations’ top climate-change official, announced his resignation yesterday. Good riddance. The bureaucrat’s departure is no surprise because his pseudo-scientific global warming religion was proved to be a hoax on his watch.
The list of problems central to the global warming fraud just doesn’t seem to end. As if hiding and losing data, the numerous errors in the U.N. Intergovernmental Panel on Climate Change and the suppression of academic research that disagrees with global warming weren’t bad enough, now comes word that basic ground-based temperature data may have been biased towards incorrectly showing temperature increases.
Joseph D’Aleo, the first director of meteorology and co-founder of the Weather Channel, and Anthony Watts, a meteorologist and founder of SurfaceStations.org, are well-known and well-respected scientists. On Jan. 29, they released a startling study showing that starting in 1990, the National Oceanic and Atmospheric Administration (NOAA) began systematically eliminating climate-measuring stations in cooler locations around the world. Eliminating stations that tended to record cooler temperatures drove up the average measured temperature. The stations eliminated were in higher latitudes and altitudes, inland areas away from the sea and more rural locations. The drop in the number of weather stations was dramatic, declining from more than 6,000 stations to fewer than 1,500.
Mr. D’Aleo and Mr. Watts provide some amazing graphs showing that the jumps in measured global temperature occurred just when the number of weather stations was cut. But there is another bias that this change to more urban stations also exacerbates. Recorded temperatures in more urban areas rise over time simply because more densely populated areas produce more heat. Combining the greater share of weather stations in more urban areas over time with this urban heat effect also tends to increase the rate that recorded temperatures tend to rise over time.
Unfortunately, all three terrestrial global-temperature data sets (by NOAA/National Climatic Data Center, NASA Goddard Institute for Space Studies and the University of East Anglia) really rely on the same measures of surface temperatures. These three sources do not provide independent measures of how the world’s temperatures have changed over time. The relatively small differences that do arise from these three institutions result from how they adjust the raw data.
The findings by Mr. D’Aleo and Mr. Watts also explain some puzzles that have bothered researchers. For example, land-based temperatures have been rising while satellite-based measures haven’t shown the same increase since 1990. Their answer is that at that point in time, the elimination of weather stations produced a false measured increase in temperatures that didn’t affect the satellite readings. There is no evidence (yet) that this effort was consciously designed to increase recorded temperatures, but that is beside the point. The crux of the matter is that fanatics about man-made global warming want to spend trillions of dollars based on conclusions from faulty data.
As the frigid winter days pass and the scandals mount, it becomes clear that claims of man-made global warming aren’t based on scientific methods at all. The hysteria is based on fraud.
Phil Jones U-Turn: There has been no global warming since 1995

- Data for vital ‘hockey stick graph’ has gone missing
- There has been no global warming since 1995
- Warming periods have happened before – but NOT due to man-made changes
Data: Professor Phil Jones admitted his record keeping is ‘not as good as it should be’The academic at the centre of the ‘Climategate’ affair, whose raw data is crucial to the theory of climate change, has admitted that he has trouble ‘keeping track’ of the information.
Colleagues say that the reason Professor Phil Jones has refused Freedom of Information requests is that he may have actually lost the relevant papers.
Professor Jones told the BBC yesterday there was truth in the observations of colleagues that he lacked organisational skills, that his office was swamped with piles of paper and that his record keeping is ‘not as good as it should be’.
The data is crucial to the famous ‘hockey stick graph’ used by climate change advocates to support the theory.
Professor Jones also conceded the possibility that the world was warmer in medieval times than now – suggesting global warming may not be a man-made phenomenon.
And he said that for the past 15 years there has been no ‘statistically significant’ warming.
The admissions will be seized on by sceptics as fresh evidence that there are serious flaws at the heart of the science of climate change and the orthodoxy that recent rises in temperature are largely man-made.
