From the Climate Audit comments section (Number 10):
When Environment Canada replaced most weather stations with Automatic Weather Observing Stations (AWOS) the results were so unreliable they hired retired former employees and others to go out with hand held instruments to check. I have no idea what data was actually placed in the ‘official’ record. The stations were so unreliable that NAVCANADA, a government agency set up to run airports, refused to accept the AWOS instruments. This led to a government inquiry chaired by Senator Pat Carney, which as usual went nowhere, despite evidence there was a problem. Sadly and ironically, one of the motivations for closing weather stations was the advent of satellite data. Typically, they found out after the fact that the satellites were very limited in what they could detect, for example, precipitation type and amount. Then they decided that the temperature data from the satellite which was better than their surface data was unacceptable because the record wasn’t long enough. At the same time they were using similar length Total Ozone Measuring Satellite (TOMS) data to introduce draconian and totally unnecessary CFC policies. These issues quickly become juggernauts, especially in governments, that it becomes the unwritten policy to continue the lie rather than determine the truth.
Mr. Timothy F. Ball, probably Canada's best known climate change skeptic, once published a letter to the editor (in the June 12th, 1996 edition of the Globe and Mail) in which he bitched about global warming and, more to the point, referred to the "so-called" ozone hole and the "Draconian policies" it had inspired.
Mr. Ball has been on the conspicuously wrong side of the great scientific debates of the late 20th century and, as the above makes clear, has been content to remain on the wrong side for decades after the science has been decided.
Ozone depletion denial competes with anti-Darwinism for the title of the "fringiest of the fringy" science award, so it is interesting to point out that not only Mr. Ball, but several of his "friends" at the Friends of Science (like Sallie Baliunas), Canada's best-known climate change denial organization, were also out fighting against the Montreal Protocol in the mid-1990s.
