It is a long term problem requiring long term solutions, most notably changes to the way we work and live. So it is deeply unpopular for politicians and media who think in terms of election or even shorter cycles.
It would be in the best interest for the more “northern” European countries to pump a lot of money south for mitigating the effects of climate change now. The EU is trying to bulwark itself against climate refugees from Africa and Asia, however it is on the best track to see a lot of internal climate refugees within the next decades. This has the explosive power to blow up the EU and NATO and lead us back into wars between EU member states, when resources such as water and arable land are fought over.
Also if Spain, Italy and Greece collapse under climate change, the strategy of letting African and Asian climate refugees succumb outside the bulwark will fail and we will see actual refugee crisis when not a few million refugees are coming, but hundreds of millions.
They’re corrupt
