Ah, so the conversation has degenerated to the "controversy" over whether burning fossil fuels could be altering the earth's climate. Look, Carbon Dioxide IS a greenhouse gas. No scientist disputes that if we just keep shoving the stuff in the atmosphere forever, eventually things will warm up. The only question is whether or not we are putting enough up there right now to have this effect.
So lets do some simple math:
1 gallon of gasoline requires about 100 tons of biomass.
1 barrel of oil makes 20 gallons of gasoline.
The world uses 85,000,000 barrels of oil per day.
Doing the simple math, we use the equivalent of
170,000,000,000 tons of biomass per day.
The earth's current biomass is estimated at
So we burn the equivalent of 1/3 of all the earth's current
biomass every single day.
I find this pretty compelling....
And don't forget the methane, which we're also pumping up there (both directly by co-release with oil drilling and fracking, and as a side-effect of arctic climate change), and which is a much more potent greenhouse gas than is carbon dioxide.
