Question.2 questions really.If the hottest day in Canada was in 1937,what cause the global warming 70 years?

Question

ago, and why,if global warming is a reality,hasn't this record been broken yet?


Hottest Day on Record - July 5, 1937. The highest temperature ever recorded in Canada was reached at Midale and Yellowgrass, Saskatchewan when the mercury soared to 45°C.

Answer 1

That is a good question. Temperatures started to rise during the 1800's when co2 levels were still low and they kept rising until the 1940's. After the war just as the industrial times were under way, temperatures started to fall despite increases in co2, and they kept falling until 1975. Then they started rising again until 1998. Since 1998 they have been falling. (That is why they are calling it now climate change. Global warming is hard to justify when temperatures are falling).

An even better question is why was the earth warmer during the times of the vikings when they settled Greenland. People who support global warming claim that is a myth, and that Greenland was never settled. They then rewrote history to eliminate this period by producing a study that showed temperatures constant for the past millennium and shot up during the twentieth century. (The so called hockey stick graph)
But the archaeological evidence does not support this claim, see here http://www.archaeology.org/online/features/greenland/

So what are you going to believe scientific hypothesis of historical fact. I chose the historical. One also has to question these so called experts who supported the hockey stick graph. Not only was it widely accepted by the climatology community it was not questioned at all. They heralded it, and many still do, as irrefutable, ground breaking proof of global warming.

But that is just evidence of the biasness of the climatology community, and why they should not be trusted. To stress my point again, I am not saying they should not be trusted because they were wrong about the hockey stick graph, but because they accepted it, without question, simply because it fit the dogma. So when people say the proof is irrefutable, and as proof they give you sites that simply say all the experts say so, you have to question it. They make such a claim because they want you to believe that since all of the experts support it, you should too, and there is no need to question things like the hockey stick graph.

By the way there are experts who do not support the theory and have said so in peer reviewed articles http://www.friendsofscience.org/documents/Madhav%20bibliography%20SHORT%20VERSION%20Feb%206-07.pdf

Answer 2

You're citing a single example from a singe country. Global warming, as the name suggests, is based on trends right around the world. As with any trend there will be anomoloies.

Conversely, if you look at the hottest temperature ever recorded in all of the countries around the world you'll see that the majority of the records have been set in recent years. In my own country (the UK) the highest temperature ever recorded was in 2005. In many other European countries 2003 and 2005 hold the record (2003 was the year of the devastating heatwave).

Globally temperatures are higher than they've been at any time for 130,000 years. 2006 is the hottest year on record, 2005 is the second hottest. 20 or the 21 hottest ever years have occured within the last 25 years. 2007 is already on target to become the new record holder with the first three months breaking all previous records.

Globally 1937 had slightly above average temperatures being 14.12 degrees C but it wasn't anything unusual. It was warmer the following year and then again 2 years later.

It's important to make a distinction between weather and climate. Weather being short term localised phenomena such as record highs in Canada whereas climate is based on long term global trends.

Answer 3

I'm getting so bored of reading this question. One hot day does not equal global warming. Global warming is global not confined to Canada, it's not about one specific day or one specific year but about trends over 10's and hundreds of years. ----------- Edit: To Jim Z (below). You display the level of you intellect by thinking there is no explanation for the cooling trend in the middle of the 20th century - there is a perfectly rational one understood by all climate scientists - look up Sulphur Dioxide, Clean Air Acts, Global Dimming etc.

Answer 4

One day's weather in one place can be anything. You have to look at the global record over many years. Here it is, verified and peer reviewed:
