Another interesting thing: one of many reasons behind the “hard line” at 1.5 degrees is that this is the level of warming were models and simulations of consequences have reasonable certainty. Beyond that level there are more unknowns and more less certainty. So 1.5 degrees should be an important target if good models are important. But, it turns out, certainty isn’t what we’re after.
