Please some tell me why we fear climate change. I have not heard "Runaway green house" for years but its still seems to be the backbone of climate change fear mongering. Change presents opportunity. The glass is half full. As a child I was taught to fear nuclear war, then as the walls came down, global cooling, now global warming. Predictions in the mid 90's lead us all to believe we would be stuffed by now. Please someone tell me what to fear as apathy, coupled with boundless optimism has given me no reason the reduce my consumption.
