The first post? Flippin' hell.
I'm an AGW agnostic. I'm not sure if the science is right or not. I'm not sure if things will be as bad as they say. But neither am I an expert on stats, climate, ecology, computer modelling or any number of other related disciplines.
What is the risk of being wrong? What is the risk of doing what is suggested?
1) We are, as a species, dead. The environment is so loopy that we can't grow enough food and die off. On the scale of "Bad things" that's up around eleventy-billion. It's really is not good.
2) We develop new technologies, better integrate public transport, create new jobs (lose others jobs), pollute less, live with natural rhythms more, stop exploiting people in the third world, reduce our dependency on energy imports, have cleaner water, less particulates in the air and thus less lung issues...the list goes on. Yes there will be problems and yes it might not be necessary. But in the great scheme of things - it's no big.
I put it to you - outcome 2) on it's own is a "Good Thing"(tm) regardless of AGW or not. So why are people so deathly afraid of option 2)? You don't have to go and live in a hut or anything. A bit of insulation, recycling, water-butt and other simple measures are a start. It's really not that hard.
You wouldn't shit where you sleep, yet that is exactly what we are doing on a global scale; and that simply cannot be sustained.
