Hottest?

Its easy to assume from the froth of alarmist media coverage about the current “unprecedented global warming” that the planet is generally getting hotter, that the whole temperature spectrum is being pushed up. Lots of photos used by climate change campaigners show dried up and parched river beds, and images meant to communicate a sense of blistering heat.

But things are not that simple.

It may be surprising to learn that all the hottest temperatures ever recorded in modern times were recorded decades ago before global warming was supposed to have started.

Here is a list of the record high temperatures by continent showing the locations and date the records were set.

There is more fascinating data at the Weather Explained  web site on the Record-Setting Weatherpage. Have a look – its very interesting.

Other highlights from the site are the highest temperature ever observed in Canada which was 115°F at Gleichen, Alberta on July 28, 1903 and lowest temperature recorded in Australia of –9.4 at Charlotte Pass, New South Wales on the June 29, 1994.

So the highest temperature in Canada is recorded decades before global warming and the lowest ever temperature in Australia is  recorded when global warming is apparently accelerating in the 1990s.

It seems that the net increase in temperatures, recorded over the past 100 years, appears to have been the result of fewer cold nights, and only modest increases in daytimes temperatures. There are many reasons for the rise in night time temperature that have nothing to do with global warming but do have a lot to do with localised disruption of night time inversion layers by local human development and land use changes.

This is clearly explained in the video lecture you can find here (about 9 minutes into the video).
