Advocates of political action on "climate change" often point to how concerted action under the Montreal Protocol solved the ozone hole problem by requiring appliance manufacturers to phase out CFC's. Great theory- except the facts contradict the theory.

From Andrew Bolt

February 11:

Good Environment says if we could unite to fix the ozone hole, we can also unite to tackle global warming: Remember, it was in 1989 that world leaders got serious about combating ozone depletion, and successfully negotiated the Montreal Protocol, an international treaty to phase out ozone-depleting chemicals. In the world international climate negotiations, The Montreal Protocol process is often held up as a success story, an example of how international environmental diplomacy works. It’s important to remember, though, that solving ozone depletion basically meant forcing industry to find chemical replacements for CFCs. A tough sell for pro-business political forces, but a relatively easy fix. Solving the climate crisis involves an entire economy-wide shift in energy production.

March 6: Uh oh:

DEPLETION of the ozone layer over the Arctic has reached record levels, the UN weather agency WMO says, blaming harmful substances in the atmosphere and a very cold winter.

Blames a very cold winter? Seems we might be safer if it got warmer, after all.
