In an IHT opinion piece written by the former president of the Czechoslovakia:
It is also obvious from published research that human activity is a cause of change; we just don’t know how big its specific contribution is.
Is it really necessary to know that to the last percentage point, though? By waiting for incontrovertible precision, aren’t we simply wasting time when we could be taking measures that are relatively painless compared to those we would have to adopt after further delays?
…
The end of the world has been anticipated many times in the course of history and has never come, of course. And it won’t come this time either. We need not fear for our planet. It was here before us and most likely will be here after us. But that doesn’t mean that the human race is not at serious risk.

Very well said. I think George Carlin also mentions this often…
PS…my son Sean at 3 and a half thought the Like a bike was retarded. He wanted one like all his friends (chain, training wheels and no helmut) riding old school!
