Does the Ozone story prove we've gotten more stupid?

It was in the 1970s that scientists first realized chlorofluorocarbons (CFCs) had worn the ozone layer thin above Antarctica. Studies have shown that, left unchecked, ozone destruction could cause higher rates of skin cancer, disrupt plant growth and destabilize the aquatic food chain thanks to an increase in harmful ultraviolet rays.

Fortunately, the world’s policymakers were proactive about environmental problems back then. Leaders agreed in 1987 to the Montreal Protocol, which phased out CFCs.

At the time, industry objected, saying the science was speculative and that regulation would be costly and lead to lost jobs. Sound familiar?

Nearly 30 years after the Montreal Protocol was signed, the ozone layer is just starting to heal, according to a panel of 300 scientists that reports every four years to the United Nations on the subject. It will take until 2050 for the ozone layer in the mid-latitudes to return to relatively healthy 1980s conditions, the U.N. report said. Around the Antarctic, where the ozone layer is the most damaged, it will take until 2075.

These same scientists are now telling us about carbon dioxide and climate change. Hum? What do you say Tim, give these same guys another shot at saving our ass?
