So lets get this straight.... the thermometer has only been in use for about 300 years
according to the "geniuses", the earth is millions of years old
recorded history is only about 6,000 years old, (maybe more if you count cave paintings).
Yet, a small group of scientists and nearly ALL leftist politicians are convinced that man is the cause of "Global Warming"
and in spite of the fact that just one of the hundreds of annual Volcanic eruptions emits more greenhouse gas than all of the industrial pollution combined at any given time
sheesh but I am just a stupid construction worker what would I know
The primary greenhouse gas is carbon dioxide. Human annual production of carbon dioxide is about two orders of magnitude greater than average annual emissions of carbon dioxide by volcanoes. (Please see the USGS page Volcanic Gases and Their Effects for details; look down the page for the comparison.) But regardless of the amount of CO2 produced by volcanoes, the simple fact is that the CO2 in the atmosphere has gone steadily upwards by about 2 parts per million per year, for the fifty some years it's been measured. It has gone up from 270 ppm before the 20th century to the present 382 ppm.
