Since carbon dioxide is responsible for only one percent of the greenhouse effect, increasing concentrations in the atmosphere are of no concern. It is unlikely that human beings can really influence the overall climate, because there are a million tons of air for each person on Earth. There is plenty of time to adjust to changes in climate. 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. Without pesticides, starvation would stalk the planet.
