The problem here is that we just aren’t cut out to understand delayed consequences. The society we build today decided co2 levels tens of years into the future, affecting temperature for yet more years into the future, affecting society for very long time. One effect of this is that consequences may be locked in long before we see them.
Propagandists love to exploit this by saying things like “there’s still time - just look at all the snow”.
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.
