WHERE'S THE HOTTEST PLACE ON EARTH?

When it comes to temperature specially surface temperature no place on earth can bit Lut desert in Iran.


Watch the video about lut



 Lut  desert ( lut Kavir) is a geologically a depression. On the other word it is a low land. lowest elevation using Google Earth indicates 109 meter above sea level. But I heard from my geography teachers at Tehran university that in some  ravines they plotted a trench which only has 75 meter above sea level. So by combination of very low land plus precipitation below 100 mm , its distant from sea and very bare soil (mostly sand and clay with no vegetation at all for kilometers) , we come to conclusion that we just discovered the hottest place on earth. 

 The image was created from data collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite, which flies overhead at about 1:30 p.m. local time, close to the hottest part of the day. MODIS records land surface temperatures, which reflect how hot the ground is to the touch.





The single highest land skin temperature recorded in any year of the study was found in the Lut Desert in 2005 and measured a stunning 159.3 F (70.7 C). Lut had the highest surface temperature in 2004, 2006, 2007 and 2009 as well.


Global warming is true

 This is a really hot news:

The temperature hit 36.2 C at Pearson International Airport in Toronto on Tuesday afternoon, breaking the previous record for July 17 of 35.2 C set last year.

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.
