If the temperature is going up, then the only reasonable solution is more and better air conditioners. There is plenty of time to adjust to changes in climate. The annual cost to the world of global warming would be negligible by comparison with the value of world output over the period in question. Certain places on the Earth are getting colder, not warmer, disproving the theory of global warming. Just a few decades ago, climatologists were concerned about global cooling.
Scientists are obviously confused about the issue.
If global warming is occurring, there's probably not much we can do about it anyway. The annual ozone hole that appears over Antarctica was first measured in 1957, long before supposed ozone-depleting chemicals were in common use. CFCs are not likely to be the source of the chlorine that is depleting the ozone layer because volcanoes are a much more prolific source of chlorine. If there is in fact some reduction in the ozone layer, the appropriate way to avoid additional cases of skin cancer would be to provide more sunglasses, more hats, and more suntan lotion. Acid rain is only a minor environmental problem.
