Going beyond CFCs, the problems caused by HFCs and HCFCs

I was struck by an interesting piece in the Daily Telegraph in the last couple of days about the continued threat to the ozone layer caused by the successors to CFCs i.e. HFCs and HCFCs.

The piece, by Geoffrey Lean says, “The use of HCFCs is accelerating, though they are to be phased out by 2030 – 10 years earlier than originally intended, thanks to an agreement partially brokered by George W Bush. But emissions of HFCs are sky-rocketing, with no end in sight: the new assessment reckons that, if uncontrolled, they could undo all the good for the climate done by banning the CFCs in the first place.”

You can read the piece – and the inevitable philosophical Climate Change sceptic/advocate exchange in the comments –  here
