The whole report, from Eurobarometer fall 2013, shows a lot of other interesting facts. Perhaps surprisingly, the only countries that seem to worry even remotely about global warming are Sweden, Denmark, Germany and Malta (global warming is 3rd or 4th most important). Perhaps not so surprisingly, these are also the countries that are feeling the least worried about their economy.
So, when you’re rich and unconcerned, you can allow yourself to also worry a bit about global warming. But otherwise, you care about more immediate issues.
