The idea that we're doomed didn't really sink in until a few weeks ago when I learned about this awful bit of chemistry which basically means in 40-100 years if we continue on our current track, the Amazon rainforest, Canadian forests and Siberian forests will all begin to emit more CO2 than they take in.
My only solace is that the evil bastards who are fully aware this is happening and yet continue to expand their cancerous industries are human. They have names, addresses, fears, hopes, families, all things we can use to CONVINCE them of the error of their ways. Likewise, global capitalism HAS the resources to address this crisis in the remaining window, it IS still, barely, a matter of poltical will.
We are the last generation that will have this choice.
I'll say that again because it's worth repeating: nature will, if we heat the planet sufficiently, begin to assist us in heating the planet
