This week’s entry for #CoolClimateData is the archive of Canada’s historical temperature and precipitation records back to, in some cases, the mid-1800’s, all of which can be found here. While it may seem to be mainly of interest to Canadians, comparisons are useful for perspective. Moreover, we encourage our readers in other countries to take a look at the site and then start digging around in your own country’s meteorological service websites to see if there are comparable records there. If you find them, please send them to us so we can share them and delve into them. Meanwhile, we’ll show you an example of why these records are so valuable in comparing climate reality to alarmist theory.
April in Ontario, in central Canada, is a time of giant swings in temperature depending on wind direction. One day it can be 0°C and snowy if Arctic cold is blowing down from the north, then the next it’s sunny and warm with a southern breeze. Before climate-induced weather amnesia set in people knew such variation was common and natural, but now they think it is bizarre and unprecedented.
With easy access to daily records we can show people that it’s not unusual. For example, we can look at the Toronto daily temperature record for April 1842, fully 181 years ago, long before your gas stove cooked the planet. The overnight low on April 1 was 0.0°C. The next day the high reached 18.3. On the 11th the high was 17.2 but on the 14th the overnight low plunged to -2.2. On the 20th the overnight low was just 2.8C but two days later, on the 22nd, the high reached 32.2.
Get the picture? The so-called normal average weather for April in Ontario is...whatever nature throws at you. And it would be cool if more people understood that.
