I’ll go way out on a limb and predict a billion people will not be displaced by “global warming.”
VAN JONES: Now, here’s a good question: should serious people focus on global political instability – terrorism, failing states, nuclear weapons – or should we focus on global climate instability – droughts, floods, extreme weather?
Here’s the correct answer: yes, both, because climate disruption will make every other national security problem worse – big floods, crazy weather – that can destabilize governments, especially weak governments. That makes it easier for extremists to grab power, or to grab nuclear weapons. No food – people riot; when the oceans rise, people flee. You can imagine a world – with some of these scenarios – with a billion climate refugees. That’s a dangerous place.
