“ as if germanies' co2 emission alone did make our world wide temperature rise so bad”

This nicely demonstrates how CO2 emissions is a collective action problem between all the world’s countries.

Any one country, even the #1 emitter the USA, giving up on fossil fuels isn’t enough to stop changing the climate via CO2 emission.

So each country can claim that its failure to build nuclear or to replace all fossil fuels with renewable and battery storage isn’t a big deal.
