Global Warming Statistics
An Offbeat Set

Global warming statistics are published in the media, now and then. Here are some stats that have never been published anywhere else than here.

Why? Because I took the trouble of standing back and look at the global warming issue from a more "global" perspective.

The results of this study are shown in graph form below.

Off The Beaten Path

Instead of analyzing surface temperature data - which can be skewed on the warm side, for a number of technical reasons already explained here, I took a more all encompassing look.

I investigated the variations of the weight of the atmosphere, over Canada, over the past 56 years.

Why choose the atmospheric pressure
as a measure of global warming?

Because warm air is lighter than cold air.

Therefore, the barometric pressure readings should have slowly dropped over the past years, with global warming.

Consider that as my definition of global warming!

The weight of the atmosphere (barometric pressure), as measured at the surface by the Canadian government meteorological stations, can be found at the National Climate Data and Information Archive Of Canada.

The barometric pressure data can be extracted freely from the database of verified and certified observed meteorological data here.

A Significant Sample

Canada has a large footprint on the map of the northern hemisphere. Its data is significantly representative of atmospheric behavior.

I looked at the atmospheric pressure data observed over four widely dispersed Canadian meteorological stations. From west to east:

Vancouver, British Columbia, on the Pacific west coast of Canada.
Winnipeg, Manitoba, in the south-central portion.
Montreal, Quebec, in the southeastern part of Canada.
St-John's, Newfounland, on the eastern tip of Canada's Atlantic east coast.

Why only four stations? I just wanted some samples of atmospheric pressure, spatially dispersed from the west coast to the east coast, over thousands of kilometers (actually about 5000 km).

I feel that such a "cross section" is representative of the behavior of the atmosphere over Canada. I also feel that the results are likely to be somewhat the same, wherever else you might want to look in the world.

The official and certified data just happens to be easy to get at, here in Canada!:-)
