Hurricane!

In the case of CFCs and the ozone layer 30 years ago, the U.S. government pushed Europe to take action in case CFCs caused a problem. Today, it's Europe thats pushing the U.S. to take action in case CO2 is a problem.

With the news that the ozone hole is recovering faster than expected it just goes to show how little we know about global climate change and that radical steps to “fix” things often are worse than just sitting back and watching things pan out. Don’t get me wrong though, I believe changing the environment in a negative way (CFCs, carbon levels in the atmosphere, pollution, etc.) are bad and harming us and the environment and we should steer clear of those as much as possible.

While the CFC ban caused local industry pain, it had no impact on the overall world economy. The same may be true for CO2.
