What would the 1980s have been without big hair and ice-cold wine coolers?

Luckily no one had to find out: Key substitutions in hairsprays and refrigerants allowed such products to exist without chlorofluorocarbons (CFCs), which were found to be ripping a huge "hole" in Earth's protective ozone layer.

Today the ozone hole, which was first spotted 25 years ago, appears headed for a happy ending, thanks to unprecedented international action.

Could a similar effort rein in climate change? And is the closing ozone hole actually making global warming worse?

1. No, a similar effort is not going to make a dent in climate change.

The work required to replace CFCs is nothing compared to what it will take to replace the burning of fossil fuels, never mind paying back nature for all the CO2 and methane we've released in previous centuries.

2. M$M is focused on the oil spill.

That ozone hole stuff is soooo 2000.
