I studied the atmosphere for several years when I was young. In all of that, I learned that we didn't know exactly what would happen to our atmosphere. However, we know it is very fragile. What we did with the ozone layer is a specific case. We changed the amount of CFCs in the air. Those substances have a life of about 1,000 years. We made that change, and the hole in the ozone layer over the Antarctic has closed up slightly.
Now we are in a situation where the changes in air currents have altered the Arctic depression. It is changing. We know we can change that. We can adopt a strategic plan to reverse the damage caused.
