This remind me global warming. The average temperature of the world increasing.

 NOAA prepared a map for month of June ,2012 which is very helpful. Red means above average. Almost all land surfaces shows above average temperature.Specially northern hemisphere with more land masses comparing to southern hemisphere shows higher values. It is noteworthy that Siberia , Greenland and north of Canada receiving higher temperature than before. In these areas glaciers and polar icebergs are reducing their sizes each year.

Hot days in Toronto

Temperature hits 36.3 Celsius which with humidity you feel it like 41C. Such a high temperature is very rare in Toronto.

 Toronto has only been that hot once, when it reached 38.3 C on August 25, 1948 according to measurements at Pearson airport.

Factor in the humidex and Thursday was felt like somewhere in the mid to high 40s.

If it doesn’t quite beat 38.3 Friday July 6,2012  could still be the hottest July day on record, beating out the 37.6 C high on July 7, 1988. Temperature records at Pearson have been kept since 1937.

A temperature record was also broken on Wednesday when the city reached a high of 36.3 C, shattering the old record of 36.1 C set on that day in 1955.

The extreme heat is caused by a high-pressure system sitting over the city that’s warding off weather and keeping the jet stream well to the north.
