The truth that was swept under the rug

World extreme temperatures. Is the globe warming?

Is the globe warming?Obviously, if the globe is warming, we expect to see temperatures rise along time. One way to look at temperatures along time is to find out how extreme temperatures behave.  Proper temperatures record is available since 1881.  I compiled the highest and lowest temperatures recorded in each continent, excluding lowest Europe temperature which the year it occurred is unknown.(Source: www.ncdc.noaa.gov/oa/climate/globalextremes.html). Here is the data: 

Extreme high and low temperatures (F) in each continent, and the years they occurred:

 Between 1881 and 2007, there are 126 years. I broke this period to two 63 year periods. 1881 to 1944, and 1945 to 2007. In the early 63 years (1881 to 1944) there were seven extreme highs and four  extreme lows. During the recent 63 years (1944 to 2007) there were one extreme high and four extreme lows. While extreme lows seem to spread evenly along these 126 years, seven out of the eight extreme highs took place in the earlier 63 years, and only one extreme high took place recently. Now I divided the 126 years to three periods. 1881 to 1923, 1923 to 1965 and 1965 to 2007. In the earlier third period there were six extreme highs and two extreme lows. In the middle third period there were one extreme high and three extreme lows. During the recent third period there were one extreme high, and three extreme lows. The table below presents the information discussed above in a more organized manner: 

Years 1881-2007 broken to two and three periods, and number of continental extreme high and low temperatures in each period.

Period Early half Recent Half   Early third Middle third Recent third
Years 1881-1944 1945-2007   1881-1923 1923-1965 1965-2007
Ext. Highs 7 1   6 1 1
Ext. Lows 4 4   2 3 2

 

My conclusion is that if the globe is warming, it must be warming very moderately. We actually see more extreme low temperatures recently, rather than extreme high temperatures.
