Re: My belief in Global Warming is getting shaky
Tim Flannery in his book "The Weather Makers" argues that early human agriculture may have stabilised the climate. Prior to the holocene it was bouncing into and out of ice age quite regularly. Early agriculture may have created significant methane bogs releasing methane into the atmosphere at small but significant doses over long periods of time.
As for the long term picture over 10's of millions of years, my very brief understanding of these matters is that continental drift itself can affect climate. But that's a looooong term effect. What we are discussing is preventing the earth hitting a climate tipping point where natural warming processes and feedbacks take over and suddenly it's too late.
Anyway, I think civilisation will make it, it's only the degrees of economic pain and suffering, and the unfair plight of the poor that really bugs me. The 3rd world will be the ones that suffer the most. We might lose certain measures of economic prosperity and that will feel like the end of the world to some, but to the 3rd world not being able to grow their crops... it really IS the end of their world.
