Dear Editor,

This is in response to the recent rebuttal to my "Shadow Knows!" article, which suggest that those seeking to expose the man made climate change hoax are getting money from big oil or are refusing to believe scientific evidence like those who would not accept the theory the world was round.

My cat, named Shadow, has hair and I have hair - at least some. Does it follow that I am a cat?

The important question is, has man made pollution in the form of carbon dioxide (CO2) and other gases caused a runaway Greenhouse Effect and Global Warming? Before joining the mantra, we should consider the following:

1. The idea that man-made pollution is responsible for global warming is not supported by historical fact. The period known as the Holocene Maximum is a good example-- so-named because it was the hottest period in human history. The interesting thing is this period occurred approximately 7500 to 4000 years ago -- long before humans invented industrial pollution.

2. CO2 in our atmosphere has been increasing steadily for the last 8,000 years-- long before humans invented smokestacks. Ice Core data indicate CO2 concentrations in earth's atmosphere move with temperature. Both temperatures and CO2 have been steadily increasing for 18,000 years. Ignoring these 18,000 years of data "global warming activists" contend recent increases in atmospheric CO2 are unnatural and are the result of only 200 years or so of human pollution causing a runaway greenhouse effect. Incidentally, earth's temperature and CO2 levels today have reached levels similar to a previous interglacial cycle of 120,000 - 140,000 years ago. From beginning to end this cycle lasted about 20,000 years. This is known as the Eemian Interglacial Period and the earth returned to a full-fledged ice age immediately afterward.

3. Total human contributions to greenhouse gases account for only about 0.28% of the "greenhouse effect". Approximately 99.72% of the "greenhouse effect" is due to natural causes -- mostly water vapor and traces of other gases, which we can do nothing at all about. Eliminating human activity altogether would have little impact on climate change.

4. If global warming is caused by CO2 in the atmosphere, then does CO2 also cause increased sun activity? Variations in sun activity are generally proportional to both variations in atmospheric CO2 and atmospheric temperature. Put another way, rising Earth temperatures and increasing CO2 may be "effects" and our own sun the "cause". This seems to relate to the fact that increased CO2 levels also follow global warming periods by several hundred years according to the ice core research.

So, if I am not a cat, then we need to expose the man made global warming hoax before it does real damage to our liberties, the economy and the world.
