Wouldn't it be odd if it were found that man is DELAYING an ice age?

Well... whether the Earth is cooling or getting warmer I doubt its because of air pollution. Man-made CO2 if only about 1/10 of that the earth produces from volcanoes and other sources.

1. An impact by a 17 mile asteroid 65 million years (threw up more debris and climate changing compounds than we could in 100,000 years in one day) Killed 75% of all species Cloud covered earth and lasted from 6 months to a year.
2. Explosion of Krakatoa, Expelled more climate changing compounds than we expelled in 100 years.
3. Every month on average a volcano will expell a decade worth of these compounds
The fact is how can we compete with these natural factors?
The fact is all the radical envioromentalists want is not a clean earth but an earth with a big socialist government that tells you what to do when it comes to everything
Carbon Dioxidevolcano.und.nodak.edu...
Present-day carbon dioxide (CO2) emissions from subaerial and submarine volcanoes are uncertain at the present time. Gerlach (1991) estimated a total global release of 3-4 x 10E12 mol/yr from volcanoes. This is a conservative estimate. Man-made (anthropogenic) CO2 emissions overwhelm this estimate by at least 150 times.
Sulfur Emissions
Andres and Kasgnoc (1997) estimated the time-averaged inventory of subaerial volcanic sulfur emissions. There inventory was based upon the 25 year history of making sulfur measurements, primarily sulfur dioxide (SO2), at volcanoes. Actual measurements of subaerial volcanic sulfur dioxide emissions indicate a time-averaged flux of 13 Tg/yr sulfur dioxide from early 1970 to 1997. [Note: a Tg is equal to 10E12 grams]. About 4 Tg come from explosive eruptions and 9 Tg is released by passivedegassing, in an average year. When considering the other sulfur species also present in volcanic emissions, a time-averaged inventory of subaerial volcanic sulfur emissions is 10.4 Tg/yr sulfur.
Volcanoes and other natural processes release approximately 24 Tg of sulfur to the atmosphere each year. Thus, volcanoes are responsible for 43% of the total natural S flux each year. Man's activities add about 79 Tg sulfur to the atmosphere each year. In an average year, volcanoes release only 13% of the sulfur added to the atmosphere compared to anthropogenic sources.
