My first response to people who bring up AGW / climate change / global warming - whatever the buzzword is now - is to ask them whether they trust the weather forecast for the coming weekend. How about next weekend? I then remind them that the same people are behind the 'forecasting' of weather a decade from now.

The climate changes on it's own naturally, we can't do shit to stop it, and I would place good money we cause less than 1% of it. Anyone who isn't a total tool knows it's an excuse to strip rights away from people and cripple the economies and enemy sovereignty of nations.
