More baseless alarmism.

1) CFCs 'ARE' the most powerful man-made GHG.
2) And they remain in the stratosphere destroying the ozone layer for about 150-years. ( Roland & Molina )
3) CFC atmospheric concentration though, pales in comparison to carbon-dioxide, methane, and nitrous-oxide.

4) Earth would have begun to enter a new ice age around 6,000-years ago, had humans not begun land clearing, fires, farming, and animal husbandry.
5) Any 'next' glaciation event is postponed by about 100,000-years.
6) Long-term ( one-thousand-year ) residence time of carbon-dioxide renders short-lived climate spikes unlikely.
