Fever-Ridden?


We’re not warming folks ... we’re actually slightly cooling. When the effects of urban “heat islands” has been removed from NOAA’s measurements, the new data show that, since 2005, the United States-has actually gotten slightly cooler ... see: Commentary Magazine Comments.

If one accepts the fact that CO2 is the bogeyman, then this may be because of our continuing conversion from coal-powered electricity production to natural gas instead ... or maybe even due to some of the wind and solar stuff. But, for whatever reason, do not believe all those banner headlines ... they’re just scare-mongering.

The best data available now says that, at least here in America, we do not “have a fever.”

Urban Heat Islands


There is a general understanding that the Earth is warming ... as much as 2 degrees Fahrenheit during the recent Industrial Age. Maybe so, but I doubt that this is an accurate number. To me it is impossible to measure the temperature of our planet ... particularly with any precision. Yes, we can see glaciers melting or permafrost disappearing ... but 2 degrees everywhere? I am skeptical.

One reason for my doubts about the precision of this number is due to the “urban heat islands” effect. When temperature readings are taken at the same locations for a long time, we know that there is a high likelihood that there have been environmental changes ... more asphalt pavings, fewer trees, running air conditioners and refrigeration that pump heat out to where it wasn’t before, etc. ... that causes bias in these readings ... thus the term, ”urban heat islands.”

Multiply this by thousands of measuring locals ... means that there is clearly a bias in this famous 2 degree global temperature increase.

Now, as to whether any change is due to our good friend, carbon dioxide ...
