Editor,
In Gary Piazzon’s June 3 letter he asked where I was “…getting this stuff,” referring to my statement that CO2 was cooling the atmosphere. I thought it was quite clear in my letter the information was from NASA. I won’t comment on the rest of his letter, which is so full of hateful and ridiculous statements against those believing that global warming is not caused by mankind, that it would be useless. I feel sorry for the poor guy.
It is apparent that the earth has warmed but I disagree with those who say that this warming is caused by mankind introducing CO2 into the atmosphere. Water vapor comprises 95 percent of the greenhouse gasses and CO2 comprises only 3.6 percent, of which only a portion is contributed by mankind.
Thus an increase in CO2 emissions has a minimal effect on adding to the greenhouse gasses, and reducing man-made CO2 will also have a negligible effect. With this in mind, is it worth spending billions of dollars and hampering the economies of the United States and the world in order to reduce CO2 emissions?
If anyone is interested in pursuing global cooling, I suggest they access the Internet. They’ll probably find more “stuff” there than they ever wanted to know.
They will find cooling in Antartica, sea ice increasing in Antartica, the Arctic and Greenland, no appreciable rise in sea levels, and thousands of scientists who don’t think mankind contributes to global warming.
It appears that most, if not all of, global warming is due to the earth’s oval orbit around the sun, its axis as it rounds the sun, and, in particular, solar activity on the sun’s surface affecting the sun’s surface temperature, thus affecting the earth’s temperature.
As a result of observations of current solar activities on the surface of the sun by Professor Valentina Zharkova of Northumbria University in England and colleagues, she suggests that we are due for a prolonged period of low solar activity from 2020 to 2053, resulting in cooler temperatures.
For Robin Charlwood, who had a letter in the same issue:
Professor Judith Curry, of the Georgia Institute of Technology and president of the Climate Forecast Applications Network, said “… The record warm years of 2015 and 2016 were primarily caused by the super El Nino.” She said evidence suggested the rate of global warming had been slower since 1998 until the 2015 El Nino. She believes science needs to wait at least another five years before it can be assessed which is more responsible for temperature rises — the natural El Nino or man-made emissions.
The obvious conclusion is that warming and cooling are natural processes occurring in the universe and mankind has nothing to do with it.
