Your arguments just don't hold water, most of them are blatantly incorrect.
There are volcanic eruptions of sufficient magnitude to carry particulate into the troposphere EVERY YEAR, in many years multiple occurrences.

Investigating climate conditions from the past does indeed have bearing on the present, and you don't have to look back 200 million years for examples.
The last major global warming was during the 1600's, when the mean temp of the earth was a full 4 degrees Celcius warmer than it is today. This era is commonly called "The Golden Age of the Renaissance". Economic and agricultural prosperity abounded at the time, greatly attributable to the effect of the warmer temperatures on crops, international commerce and exploration, and milder living conditions for the populations.

This is not speculation, it is fact.

The allegories you use as comparisons are ridiculous. You can't stop droughts, hurricanes, or climate change. The most you can do is prepare to survive them.
You could stop a mugger of course, but that hardly has global impact.

The very papers submitted by the organizations you reference as the authority on global warming have been refuted by the same scientists who supposedly endorse them.
In fact these same scientists point out that they didn't even see these findings they supposedly endorse until after they were published.

A recent study shows that if mankind gave up all industry and parked every car in the world, today, it would take more than three hundred years for there to be an observable variance in greenhouse gases. That's because mankind contributes less than 3% to greenhouse gas accumulation.

Stop the fear mongering.
