Temperature Trends at Different Latitudes

Gord Miller has responded to my challenge of his claim that Canada is showing a faster increase in average temperature than the rest of the world.
 
This is his reply:

I have reviewed the letter from Richard Wakefield, and have found nothing in it to change my observation in the September 22nd article you published that global warming is occurring faster on average in Ontario than in the rest of the world.

I am not the only one to hold this view. I am sending you a graph published by the National Aeronautics and Space Agency in the United States which clearly shows that, over the decades, global warming has been proceeding at a higher rate at much higher latitudes, as in Ontario. A NASA map, also attached, shows the
temperature anomaly patterns for the three warmest years on record; note the pattern of rapid warming at higher latitudes in North America.

Closer to home, the Ministry of Natural Resources published a study in 2007, “The Known and Potential Effects of Climate Change on Biodiversity in Ontario’s Terrestrial Ecosystems” and on page 2 the authors wrote…

Although the average annual global temperature warmed about 0.74°C during the past century (IPCC 2007), the warming trend in Canada was double the  world average. However, the warming was not uniform across the country. For example, average annual temperature increased about 2.0°C in northwestern
British Columbia and the Kluane region of the Yukon Territory, 1.2°C in southcentral Canada, and was unchanged in Atlantic Canada over the same period (Environment Canada 2006).”

The Natural Resources study clearly uses more up-to-date climatological data than the Meteorological Service of Canada study cited by Richard Wakefield.
But even the study he cited does not support his thesis. The study states in fact “Annual mean temperature has warmed an average of 0.98C in southern Canada over the last century” and “The causes of different spatial and temporaltrends, such as increase atmospheric greenhouse gases and natural climate variability,
cannot be addressed by a study of this nature.”

I hope this information is helpful

These are the graphs he presented:

Wow, look at that rapid increase for us here in the north! We’re DOOMED!

Not.

It makes me wonder some times. What do we have in the northern latitudes that they don’t have in the tropics? Think carefully….

Don’t know?

WINTER!

We have winters, where is gets real cold. Tropics don’t have a winter. So since our winters are becoming less cold, but the summers not as hot, which is increasing our average, then yes, our average would be increasing faster than the tropics!

Of course, we see the problem with these graphs that Miller is accepting as gospel for global warming. They are AVERAGES! Not measurements of actual temps. Miller needs to look at the full range of temperatures throughout the year, as presented in this blog, to see that that average is a meaningless number without the context from which that average is calculated.

Second point. Southern Hemisphere and tropical temperature data is very very poor and spotty. Mid Africans didn’t record temperature since 1900s. People in the southern part of South America didn’t take daily temperature readings since 1900. Even Australian temperature readings are spotty at best.

So to rely on such incomplete data, to pin an entire economy on such incomplete data, is reckless.

I don’t care which people or which organizations stand behind their myth (argument from authority), all that counts in science is evidence. And that evidence does not support that the planet is heating up.
