It isn't enough on climate change to argue is it happening and what is causing it? I acknowledge that climate change exists, although even with this data I'd still assert that we go through cycles. Man certainly plays a role in the climate and his role is debatable. But that isn't enough. The real question to answer is what should we do about it? A person who's analysis I admire in this debate is Bjorn Lombard. He makes the case that the best way to deal with climate change is through adaptation. I've attached a link where you can find his conclusions.
