Toronto blogger embarasses NASA climate experts

Stephen McIntyre, amateur meteorologist from Toronto, has embarrassed NASA scientists by catching an error in recent climate-change data: climatologists at NASA's Goddard Institute of Space Science (GISS) in New York now concede that 1934, not 1998, was the hottest year in U.S. history. NASA now shows that 1998 is the U.S.'s second-hottest year and that five of the 10 warmest years on record in the U.S. date from before 1939. McIntyre first emailed NASA on August 4 saying he'd discovered inexplicable jumps in temperature in its climate change data from 1999-onwards. Around that time, NASA's temperature readings have all been too high, to a maximum of 0.15 C. The worldwide numbers remain unchanged, with 1998 and 2005 tied as the hottest year on record.

The mistake found has led to accusations and finger-pointing over whether NASA's error was genuine. Climate-change skeptics are accusing NASA of inflating the numbers to promote global hysteria over the environment and others are accusing NASA of trying to keep the error quiet. Meanwhile, climatologists at GISS say their critics are making a mountain out of a molehill and that the differences in the recalculated temperatures are so insignificant that they have no impact on the overall trend towards global warming. They attributed the error to a new data collection system established in 2000 that used different methods than the previous one.

Hahaha @ ppl wo says that 0.15 error is nothing :

- A chrono error of 0.15 could change the result of a world record;
- A 0.15 error would have determined another F1 winner at the last race;
- A 0.15 error changed the whole statitics scheme of which year was the hottest!

Pip'

Those who say that global warming is not happening are no different than creationists who say that evolution isn't true. They both latch onto little errors and try to make them seems much more than they truly are.

If at first the evidence was not enough, all they now need to do is look out of the window.

If only it were that simple, but there are still people around who believe that the Earth is flat and the center of the universe.... Some won't even accept a literal mountains worth of evidence. They look for god in the gaps..

Indeed. The error shouldn't have been made but it certainly wasn't a conspiracy to promote mass hysteria.

Of course, its not like US departments have a history of making up wild stories to support their plans.
