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).
