re: #155 Obdicut

I’m not asking about historical data. I’m asking about very simple science: If you take our earth’s atmosphere, put it in a greenhouse, and increase the amount of CO2, will it trap more heat than if the greenhouse was full of normal atmosphere?

“full of normal atmosphere”… in a greenhouse? What about the sun, cosmic rays, clouds, the oceans?? You want to cherry pick the scenario to fit your idea of global warming. The earth system is far too complex to try to simplify it down to a greenhouse and increasing CO2.

Besides if you overlook history, you are severely limiting your overall understanding of the how complex the earth’s entire ecosystem is. Is man screwing things up - certainly. Do we have all the answers on exactly how we are screwing things up - definitely not.
