ISIS IS NOT AN EXISTENTIAL THREAT TO THE UNITED STATES. CLIMATE CHANGE IS A POTENTIAL EXISTENTIAL THREAT TO THE ENTIRE WORLD

 “Right now, across the globe, you’re seeing places that are undergoing severe stress because of globalization, because of the collision of cultures brought about by the Internet and social media, because of scarcities—some of which will be attributable to climate change over the next several decades—because of population growth. And in those places, the Middle East being Exhibit A, the default position for a lot of folks is to organize tightly in the tribe and to push back or strike out against those who are different.

“A group like isil is the distillation of every worst impulse along these lines. The notion that we are a small group that defines ourselves primarily by the degree to which we can kill others who are not like us, and attempting to impose a rigid orthodoxy that produces nothing, that celebrates nothing, that really is contrary to every bit of human progress—it indicates the degree to which that kind of mentality can still take root and gain adherents in the 21st century.”

So your appreciation for tribalism’s power makes you want to stay away?, I asked. “In other words, when people say ‘Why don’t you just go get the bastards?,’ you step back?”

“We have to determine the best tools to roll back those kinds of attitudes,” he said. “There are going to be times where either because it’s not a direct threat to us or because we just don’t have the tools in our toolkit to have a huge impact that, tragically, we have to refrain from jumping in with both feet.”

“isis is not an existential threat to the United States,” he told me in one of these conversations. “Climate change is a potential existential threat to the entire world if we don’t do something about it.” Obama explained that climate change worries him in particular because “it is a political problem perfectly designed to repel government intervention. It involves every single country, and it is a comparatively slow-moving emergency, so there is always something seemingly more urgent on the agenda.”
