If the idea that Man is changing the rate or extent of climate change turns out to be right then maybe we'll be helping our descendants survive. OTOH if it all turns out to be just hot air then we will still have addressed pollution in a more strategic fashion.
If we do nothing then we won't be in a position to recover from the omission once we're beyond the tipping point; I (for one) am quite fond of my children and I dare say I might even be concerned as to my putative grandchildren's survival too. So,
IMHO, it all boils down to Dirty Harry:
Do we feel lucky?
As traders, I'd suggest that "feeling lucky" would be ridiculed as a strategy so why should that not be the case when it's about the survival of the species?
