The Ozone Hole: Closing the Gap

In the 1980s, scientists began to realize that ozone-depleting chemicals, such as chlorofluorocarbon (CFCs), were creating a thin spot—a hole—in the ozone layer over Antarctica. Through an international effort to decrease the use of CFCs, the ozone layer is starting to mend, and scientists believe it should mostly recover by the middle of the 21st century. This series of satellite images shows the ozone hole on the day of its maximum depth from 1979 through 2018.

More junk science!

The ozone hole is a naturally occurring phenomenon and nothing we did or do will affect it

Just another reason for DuPont to make billions off of their new refrigerant patents.

New cars now have R1234yf and it's flammable.
