Repairing The World Again

While the Earth roasts there are some real dingbats around trying to deny what they are seeing with their own eyes but they are in the minority and as we showed in the 1990's, we saved ourselves once and we can do it again.
Chlorofluorocarbons (CFC's) are human-made chemical compounds containing carbon, chlorine, and fluorine which were once widely used in aerosol sprays, refrigeration, and air conditioning until scientists worked out they were destroying the Earth's Ozone layer which shields us fragile humans from the Sun's harmful radiation and the Worlds Governments got together to phase them out.
The Environmental Protection Agency (EPA)  projects that the ozone layer is responding by healing and by 2066 will be restored to it full, life saving glory.  
Unfortunately the CFCs were replaced them with hydrofluorocarbons (HFCs) which don’t harm the ozone layer, but they are extremely powerful greenhouse gases with some trapping thousands of times more heat than CO2 but then Humanity always did have a knack for solving problems by creating even bigger ones but once again the Globe got together and decided to phase out HFC's in the same way that they did with CFC's.
By acting, humanity avoided a future of extreme UV exposure leading to widespread skin cancers despite the chemical industry who dismissed it and launched a PR campaign in defense of the compound which echoes today with the Fossil Fuel industry who try to deny that their products are responsible for the man made climate change causing us such problems today.
So if we are capable of a concerted global effort to tackle a problem no single country could ever hope to fix alone, why not now with Climate Change?
The science is clear to everyone and we are perfectly capable of repairing what we broke in the first place and as we have no second home or anywhere to escape to, we have no choice, we HAVE to fix it again.
