I wrote earlier about a particularly dumb argument against global warming–the argument that an unusually cold day shows that global warming just isn’t happening. Well, there doesn’t seem to be an argument dumb enough that someone can’t make it dumber. Take it away, Tim Blair:

Comical protest news from Montreal:

Thousands of people ignored frigid temperatures to lead a worldwide day of protest against global warming.

Was it unusually cold that day in Montreal? Well, no. December 3 was slightly warmer than the average December day in Montreal.

Wait, there’s more!

Global warming protests cure global warming. Further scientific evidence of this phenomenon from Montreal, which lately was host to 10,000 global warm-mongers:

Record snowfall overnight forced the cancellation of 200 flights at Montreal airport, school closures and caused havoc on roads.

More than 41 centimetres of snow fell on Friday, Andre Cantin, a spokesperson for Canada’s meteorological service said.

The storm will go down in history as one of the biggest snowfalls in a single day in Montreal in December, beating a record of 37.8 centimetres (15 inches) on December 27, 1969.

As it happens, December 16, the day of the snowstorm, was also warmer than average for December. Oops.

Update: I must have struck a nerve because Blair has now responded twice to this post. The first response was that it was just a joke so the temperatures don’t matter and then he changed his tune: Dec 3 was a whole 1.9 degrees cooler than the average Dec 3 temperature. Shock Horror! It’s another Ice Age!
