The equator contains billions of people. It's quite hot around there. Wet bulb temperatures often near the edge of survivability outdoors. It's worse now with 1-1.5C warming. If we don't stop, and we get to 3-5C warming, this could lead to large scale migration to Europe in pursuit of liveable climate. And warming won't stop unless we stop emitting greenhouse gases.
