Climate Watch: Are Temperatures Constantly Increasing?

I hope you are able to stay cool, without resorting to the limited “cooling centers” some towns like Tucson make available. It has been hot, but is it a record and an ominous trend?

We might dismiss the high temperatures in the 1930s as mere anomalous “weather,” but are we now in a climate warming trend?            

According to this graph from the 1975 National Academy of Sciences, the 1930s were at the peak of a warming trend that began around 1890, before the great increase in burning fuels like coal, and began to decrease as fuel use increased.

Alternating this graph with one prepared by the National Oceanographic and Atmospheric Administration             (NOAA) by manipulating the data, one can see the effect of erasing the Northern Hemispheric warmth from 1890 to the mid-1950s and reducing the warmth of 1938 by nearly half a degree Celsius. Climategate emails show that erasure of the prior warmth was a coordinated effort to “hide the decline.”

 Politicians’ proposals to “address” the climate threat are based on this data.
