More Global Warming Mullarkey

This time from Montana:

Perhaps Governor Schweitzer, with a state bureaucracy at his disposal, couldn't produce evidence of warming around Glacier because it doesn't exist. I looked at average temperatures at the Kalispell airport from 1899 to 2005. For that period, annual temperatures are quite steady -- a linear regression even yielded a negative slope. What about the much ballyhooed summer temperatures? I looked at July and found the same thing. The narrower period used by the USGS authors -- 1910-1980 -- produced cooling results for annual and July temperatures. I would be interested to see how the USGS authors found increasing temperatures. We really don't know if the area around Glacier is warming.

What evidence is there for man-made global warming melting the glaciers in Glacier National Park? None. Glaciers in the park have been consistently melting since man laid eyes on them. They've come and gone before, as they probably will again. Schweitzer is right to admit that there's nothing we can do now to stop the glaciers from melting. But to claim them as a reason for his synfuels proposal is awfully arrogant -- for the man Schweitzer and for Man. Global warming theory feeds a natural inclination to see ourselves as the problem and/or the solution. In this case, we're neither.

If global warming were truly underway, wouldn't temperature data across the globe show an increase? The mean temperature tells you precisely nothing given so wide a standard deviation.

Moreover, if global warming were occurring, wouldn't one rule out the primary sources for heat on this planet---say, the sun or internal vulcanism---before leaping to the conclusion that America is to blame?
