This generational gap mimics the one currently playing out on climate action, Dana Nuccitelli argues for The Guardian, as a 2014 poll found 74% of Americans under 30 support government policies to cut carbon pollution, compared to just 58% of respondents over the age of 40, and 52% over the age of 65.

The problem, Nuccitelli argues, is that young people will have to live with the consequences of the decisions we make — or don’t make — today. While previous generations prospered through burning fossil fuels for cheap energy, unaware of the climate impacts, today’s generations have no excuse, and no time to lose on inaction: As Nuccitelli puts it, “[W]e’ve already reached the point where even contrarian economists agree, any further global warming we experience will be detrimental for the global economy.
