Scroll down for part 2 global warming subject which focuses on Montreal, Quebec this time

Historical Weather
1940: Strong winds drifted snow to over 1 m, blocking roads to the orphanage near Point-aux-Trembles, QC. Everyday, the nuns expected the snow along the 2.5 km road to be cleared. Meanwhile, two heroes-a milkman and a baker-hauled more than 400 litres of milk and 50 loaves of bread on toboggans daily over the snow drifts to the institution for the 400 small children and babies and many nuns.

Environment Canada forecast for my Area issued at 3:45pm EDT

Normals for March 28th: 6C and -3C

Hello everyone! The weather is extremely boring so I had plenty of motivation to publish the second part of my series on `Global Warming`. I must add that I`m very happy to see that for a week of forecasting a warm-up to slightly above normal temps midweek this week it is really coming and exactly on time. I find it peculiar that Accuweather is forecasting a potential big snowstorm in the big cities for april fools. I doubt it will happen, especially considering temps will be in the 40`s in my area late week but hey, anything can happen...

Montreal, Quebec

Click for a much larger image.

Montreal, Quebec is the second-largest city in all of Canada and the largest in Quebec. In 2006 the metropolitan area of Montreal was home to 3,635,571 inhabitants. The city experiences all kinds of weather from not-so-common blizzards and extreme cold in winter or spring to long heatwaves in the summer to gusty 100km/h northwest winds in autumn. Average temperatures in January are around -10C and in July a warm 20C. Highs are around -6C and 26C respectively. Temperatures have been known to drop to a dangerously cold -35C below a massive arctic High or with the windchill, temperatures can feel as low as -40C on a gusty January night and can rise to a scorching 38C or 100F with 70% humidity which makes the temperature feel more like a dangerous 45C+ or 120F+. Warm, Humid summers and cold dry winters are the norm in this City located in the St-Lawrence river valley. Normal snowfall amounts are between 200-250cm or about 6.6 to 8.2 feet a year.
All time record high: 37.6C (99.6F) August 1st, 1975
All-time record low: -37.8C (-36F) January 15, 1957
As far as global warming goes, there is clear evidence that this region is warming and even though it's not as bad as Labrador's coast, which I talked about on the first part of this series, it still is significant. Records only go back to 1942 but that is enough to suggest global warming is having clear consequences on this region's average climate. Winters and springs are trending much warmer and that has encouraged bedbugs infestations in the area. As a person living close to Montreal, I notice firsthand how winters have significantly warmed. We used to have snow by late-November on the ground and now snow arrives on average in late-December and winters are also much shorter then they used to be. The absence of extreme cold in the last several years is shocking. We have yet to reach a temperature of -30C since 1994 and in quite a few years the lowest temperature doesn't even reach -25C.

Trends per decade
January high +0.06C, low +0.17C
February high +0.18C, low +0.17C
March high +0.16C, low -0.04C
April high +0.27C, low +0.07C
May high +0.15C, low +0.07C
June high +0.05C, low +0.05C
July high -0.03C, low +0.03C
August high +0.02C, low +0.05C
September high +0.11C, low +0.04C
October high -0.25C, low -0.14C
November high +0.11C, low -0.12C
December high +0.30C, low +0.28C
Overall +0.08C
Precipitation +12.8mm or 0.5 inches

UPDATED THE GRAPH, REMOVED 9.8C AVERAGE FOR 1943 AND REPLACED WITH THE CORRECT READING OF 5.3C WHICH MAKES A HUGE DIFFERENCE ON OVERALL MEAN TEMPERATURE TREND. I KNEW SOMETHING WAS FISHY...

The third part in this series will focus on Calgary, Alberta. We are witnessing bug infestations much farther north and pine beetles are slowly destroying forests on the west coast.

Energy from the Sun Has Not Increased The amount of solar energy received at the top of our atmosphere has followed its natural 11-year cycle of small ups and downs, but with no net increase. Over the same period, global temperature has risen markedly. This indicates that it is extremely unlikely that solar influence has been a significant driver of global temperature change over several decades. Global surface temperature (top, blue) and the Sun's energy received at the top of Earth's atmosphere (red, bottom). Solar energy has been measured by satellites since 1978.

Alright Michael, thanks for showing me this information! I admit I made some crazy assumptions based on almost nothing... I should just stick with facts for now as I have very limited knowledge about all of this. I am learning though and surely keeping an open-mind about the subject but I guess it wasn't enough. Also, I am not a denier. I believe in global warming and I know that the arctic is impacted much more significantly than mid-latitudes. Thank you again for pointing out the errors... From what I knew it made sense but I should shut up because I obviously don't know much. I've got projects though and I'll continue to learn. Member Since: 17 octobre 2006 Posts: 59 Comments: 1050

Very interesting stuff... I don`t know that I was thinking when I wrote this... I have updated it and it's a little more on the logical side and it describes what I`m seeing. Assumptions are out of the window! Member Since: 17 octobre 2006 Posts: 59 Comments: 1050
