there is anthropological evidence of increases and decreases of temperature for as long as we have been able to track things. have we exacerbated the issue? sure. have we doomed the planet due to climate change? unlikely. have other actions that we insist on repeating put us in jeapordy? possibly.
if nothing else the focus on this issue has gotten people to clean up their acts, think about renewable energy. actually recycle. try to walk more softly on the planet
