Global warming.


I thoroughly enjoyed and agreed with the articles on global warming (September 18 issue) by Dennis Behreandt, wherein he suggested that solar activity is to blame for the alleged rise in the "earth temperature," a questionable parameter to begin with.

Let us not forget that back in 1975 scientists were gloomily predicting a new ice age, apparently unaware of the rise in global temperatures taking place in about that same range of years, according to the new "hockey stick" graph, as best as I can read it. Why were they then predicting a new ice age when the graph clearly indicates what is now regarded as an alarming rise in Earth temperatures?

 global warming necessarily rests upon the presumptions that (1) the sun is an isotropic Refers to properties that do not differ no matter which direction is measured. For example, an isotropic antenna radiates almost the same power in all directions. In practice, antennas cannot be 100% isotropic.  and isochronous Time dependent. Real time voice, video and telemetry are examples of isochronous data.

A moving charge gives rise to a magnetic field, and if the motion is changing (accelerated), then the magnetic field varies and in turn produces an  across the entire electromagnetic spectrum electromagnetic spectrum

Both of these propositions are preposterous, and as a result, one must be led to the conclusion put forward in your article that any heating of the Earth, and there may be some evidence that such is taking place, is due to cosmic influences, about which we can do nothing.
