It will be too late
Currently there are three assaults on climate change. The first is on the integrity of the scientists who support human activity in climate change. Second is that humans are not capable of affecting the climate. Lastly, that the science is not settled.
Many opponents of climate change indicate that the whole thing is a hoax. This would mean that the Intergovernmental Panel on Climate Change, the National Academy of Scientists, the American Metrological Society and the American Geophysical Union, when taken all together, includes over 1,000 scientists, have formed a conspiracy or hoax on the public.
Regarding human activity, the EPA administrator actions regarding the ozone depletion crisis, especially the discovery of the Antarctic ozone “hole,” led to international cooperation to eliminate man-made halocarbon. Without action, the ozone “hole” would have expanded until eventually it encircled the entire earth.
Regarding climate change being unsettled science, this type of opposition began in 2003 under the guise of “sound science.” This approach has been used to delay or prevent regulations regarding ozone depletion, second-hand smoke and endangered species. The only absolute proof is to wait until it happens, but by then it will be too late.
