Sure Europe took more action than most, but those actions are clearly now seen to be a) insufficient, and b) limited to a small proportion of the world's emissions. China and the US more than cancel out any improvements the EU made. They
might have been sufficient if everyone had played, though I doubt it. They didn't, so the goal posts have moved significantly. There's still only one planet.
Apologies for my shorthand purely for brevity, I thought the real progress was quite well known. The ozone hole is not actually closed yet. The trend is very much in the right direction thanks to those international treaties on CFCs. There's also huge hysteresis in the system so change follows very slowly indeed. The trend of improvement has indeed slowed, apparently courtesy of China breaching the treaty they signed - they have form here, not just the recent breach of Hong Kong treaties. Sadly the UN and international community doesn't seem willing to sanction China for breaches of anything much.
At current progress - depending on China - a century or a little over looks to be right on the money. The clock is at about 50 years. Nonetheless it looks like we found the right cause and remedy, and acted in appropriate time.
Less exaggerated catastrophe, more bloody accurate estimate I'd say. As your BBC link confirms. Here's a link with some trend graphs - see for yourself.
Where's the exaggeration? The odd piece reporting badly doesn't make the case - the media is often terrible reporting science. Any science. :)
