We have just had the warmest winter on record and there is no evidence of global warming?

Anyway, as I have pointed out before, it doesn't matter what is causing the global warming: whether it is natural, man-made or some combination of both. Given the warming is occurring and given humanities full use (overuse, in some cases) of many of the earth's natural resources (I'm thinking of farmland, fresh water, fish stocks and similar resources here), any climate change beyond the very minor will have major, major impacts.

If the cost of stopping or seriously slowing the change is 10% of the cost that will be incurred if man does nothing, why not spend the 10%, T-D?. And don't tell me we can't mess with God's plan, because we do that everytime we create smog or burn enough forest that the weather is affected (in Indonesia, for example), or wipe out another species or ten.
Grow up, and accept responsibility for your planet!
