Not only is Canada's role in global warming negligible, we are more likely to gain from it.

W.D. Hogg, 2002: Homogenization of daily temperatures over Canada.
Journal of Climate, 15, 1322-1334. Climate Research Branch, Meteorological Service of Canada, Downsview, Ontario, Canada ABSTRACT Recent studies have shown that, since 1900, mean annual temperature over southern Canada has increased by an average of 0.9°C, with the largest warming during winter and early spring. Every season was associated with greater increases in minimum temperature as opposed to maximum, thus resulting in a significant decrease in the daily temperature range (DTR). The second half of the twentieth century was associated with significant winter and spring warming in the south and west, and cooling in the northeast. However, no significant changes in DTR were observed during this period. This investigation goes beyond the annual/seasonal scales by examining trends and variability in daily minimum and maximum temperature with particular emphasis on extremes. Using recently updated, homogenized daily data, spatial and temporal characteristics of daily and extreme temperature-related variables are analyzed on a seasonal basis for the periods of 1900-98 (southern Canada), and 1950-98 (the entire country). From 1900 to 1998, the majority of southern Canada shows significantly increasing trends to the lower and higher percentiles of the daily minimum and maximum temperature distribution. The findings translate into fewer days with extreme low temperature during winter, spring, and summer and more days with extreme high temperature during winter and spring. No consistent trends are found for the higher percentiles of summer daily maximum temperature, indicating little change to the number of extreme hot summer days. Over the southwest, increases are larger to the left-hand side of the daily minimum and maximum temperature distribution, resulting in significant decreases to the intraseasonal standard deviation of daily temperature. The 1950-98 results are somewhat different from the entire century, especially, during winter and spring. This result includes significant increases to the low and high percentiles over the west, and decreases over the east. This analysis reveals that the largest individual daily temperature trends (both minimum and maximum) occur during winter and early spring, when substantial warming is observed. For summer, increases are only associated
with daily minimum temperature. Autumn displays varying results,
with some late season cooling, mainly over western regions. The observed
warming trends have a substantial effect on several economically
sensitive indices. This effect includes significant increases in the
number of growing and cooling degree days and significant decreases in
heating degree days. In addition, the length of the frost-free period is
significantly longer over most of the country. Some facts to keep in mind........ About 95 percent of the greenhouse effect
- the atmospheric warming due to the trapping of solar energy that makes
life possible on Earth - is due to water vapour, 99.999 percent of which
is of natural origin. The other 5 percent of the greenhouse effect is
due to carbon dioxide, methane, nitrous oxide and other miscellaneous
gases. |

Russian scientist says Earth could soon face new Ice Age - Jan 24/08
ST. PETERSBURG (RIA Novosti) - Temperatures on Earth have stabilized in the past decade, and the planet should brace itself for a new Ice Age rather than global warming, a Russian scientist said in an interview with RIA Novosti Tuesday.
"Russian and foreign research data confirm that global temperatures in 2007 were practically similar to those in 2006, and, in general, identical to 1998-2006 temperatures, which, basically, means that the Earth passed the peak of global warming in 1998-2005," said Khabibullo Abdusamatov, head of a space research lab at the Pulkovo observatory in St. Petersburg.
According to the scientist, the concentration of carbon dioxide in the Earth's atmosphere has risen more than 4 percent in the past decade, but global warming has practically stopped. It confirms the theory of "solar" impact on changes in the Earth's climate, because the amount of solar energy reaching the planet has drastically decreased during the same period, the scientist said.
Had global temperatures directly responded to concentrations of "greenhouse" gases in the atmosphere, they would have risen by at least 0.1 Celsius in the past ten years, however, it never happened, he said. [read full report]

CBC - Global Warming Doomsday Called Off - Google Video - Sunday May 13, 2007
A very good unbiased documentary about the real cause of global warming. Although I think that Martin Durkin's The Great Global Warming Swindle is very informative, it is not the only documentary of its kind. In 2004, CBC (Canada) has produced a similar 45-minute-long film. It discusses many topics that are not covered in the Swindle such as the hockey stick graph, from the viewpoint of Willie Soon and Sallie Baliunas.
