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. :)

Sorry but those actions where clearly sufficient. If all countries had reduced their CO2 emissions like the EU block did, we would be in an excellent state. The reduction needs to keep happening in a steady pace, not have a sudden shift like these extremist environmentalist are calling for.

My issue with those analysis is that they are political, not environmentalist. For instance, if you look at India in those same analysis, you see they are doing great (although having increased they CO2 emissions in 300% and set to soon become the 2nd biggest polluter by a long margin).

In fact that's my issue with this all movement: It seems to take roots in contesting Western Society by using the climate crisis to force major political change in the West by disrupting the all economic output (because this will be what happens if you suddenly break the energy consumption by several %), and then build a society according to the political views of a minority that thinks they know best.

At the same time, that won't stop global warming at all, since the emissions on the West are already the minor part of the global emissions (due to china) and soon will become an even smaller part (due to India).

No, they weren't. They were meant to be a first step of many as part of a sustained programme of international action. We mostly didn't bother, so it's rather academic anyway. We lost the luxury of 30 years of steady incremental managed and subsidised change and now need to apply the emergency brake.

I'm not sure which environmental extremists you are thinking of. Environmental extremists like the UN IPCC - the Intergovernmental Panel on Climate Change, whose current chair is an economist - are contesting Western society by disrupting all economic output? There was me thinking they are working to try and keep the possibility of some economic output by avoiding civilisation crash.

This is not some cliche hair-shirt 70s environmental hippies going overboard on the ganja at peace camp. This is chemists, meteorologists, climatologists and economists, etc appointed by the world's governments. Governments that are, I assume, mostly not seeking a rerun of 1917.

XR want to achieve the IPCC's aims. Nothing more. I see regular people from a diverse mix of very normal backgrounds with regular jobs. I see no reds under the bed.

The EU reduced their emissions by close to 30% in 30 years. These actions were obviously sufficient. Problem is that only the EU (what what are now the EU members) took the effort. The EU should be praised as an example and instead we have a bunch of environmentalist extremists shutting down airports here with drones.
