What makes the climate crisis a global crisis is the general concern, some countries may be affected more and others less, especially differently. Global also means that all countries, within the scope of their possibilities and their responsibility, must contribute to counteracting the hitherto unchecked increase in temperature. So no free-riding, no dispensation from climate policy efforts, no postponement of the exit from the age of fossil fuels in the very distant future. Democratic countries just as much have to participate as autocratically led ones. And yet there are serious differences in terms of the respective contribution to climate change.
The developing countries are quite right when they complain that the industrialized countries, historically primarily responsible for the cumulative emissions of greenhouse gases and thus for climate change, are sounding the alarm and making nice speeches, but are largely leaving the poorer and ecologically particularly vulnerable countries alone.
There is no way (and no argument) around the fact that the affluent countries have to help the “global south” with climate protection and adaptation to change.
Yes, they too are facing enormous changes that will cost a lot of money.
In quite a few developing countries, however, their very existence is at stake.
