You don’t hear much about the ozone hole these days.
I guess we filled it in.
There is still an ozone hole. It’s just that there is more money and control in CO2.
BTW, we are changing refrigerants again, this time for AGW. Even though virtually all of it is recovered these days, it somehow gets out and wreaks havoc. And now, in preparation for future demands, the leftist theoreticians are writing about the inherent immorality of A/C. If they get their way it will be a hot time in Georgia.
