I believe global warming is liberal sensationalist propaganda designed to enact more government control over our personal lives. The earth has been around for hundreds of billions of years and has survived countless natural disasters of all kinds, far exceeding anything man is capable of replicating. In my opinion, claiming that man is having some sort of catastrophic effect on a planet as old as ours is absurd.
No, governments should not focus to adaptation to global warming rather than to the mitigation of global warming, as it is not too late to focus on the latter. We still have time as a world to undo some of the damage we have done, and lessen any future damage.
