Quote from jonnysharp:
It's not a matter of proving whether we create global warming or not, it's a risk management issue.
Even if it's a 50% chance we are the cause it's in our best interests to mitigate the risks by changing our ways, not waste time debating whether or not we are the cause.
Why not create a cleaner more energy-efficient world?
Seems to me, the cure is worse than the disease. So thanks, but no thanks.
