Should you believe in climate change?

It is amazing that the evidence for climate change and mans impact on the climate is overwhelming, yet there seems to be people who can argue the fact. I work with lots of guys who are staunch republicans and will argue that climate change is on a natural curve and mans impact is minimal.

I have a new project for myself though, I want to find out how many tons of waste products are put into the atmosphere by man made stuff, autos, planes, factories, homes etc...and put that into terms of how many volcanoes would have to erupt per week to match that output per week.

For electrical generation in the US, you can start with EPA's eGrid.

Of course, that's a limited sub-set of all the man-made emissions from all sources, and from around the world.

A good article on the combined effect of climate change and peak oil.

I tried doing this myself a few years ago and posted the results here in the Cellar.

Even the largest eruption in recent times, Pinatubo in the Philippines, produced between 42 and 234 million tons of CO2. (1, 2) so even that year, volcanoes didn't come anywhere near producing the CO2 that mankind did.
