Let’s see, there is quantum mechanics and thermodynamics, which are primarily statistical in nature. Indeed, QM says the world can only be known probabilistically.

Pretty much all of science related to human health is probabilistic — e.g. not everybody who smokes will get sick from it, but a substantial fraction will.

Chaos theory makes clear that all complex systems dependent on myriad initial conditions (such as weather or climate) are inherently nondeterministic — not because the world is quantum mechanically un-determinable at a large scale, but because the initial conditions can’t be measured with sufficient accuracy.

When you went to high school, you were dealing with rudimentary calculations that are all approximations of the real world — frictionless systems and the like. Your school ever ask you to calculate something as simple as where a metallic pendulum dangling above 3 magnets will come to rest? Didn’t think so.

Probability ain’t the same as “what if.” If you play Russian roulette with three bullets in the chamber, there is some infinitesimally unlikely chance you will never kill yourself, but somehow my guess is you understand probability well enough to know that I can scientifically state that doing so is suicidal.

If we keep pouring unrestricted greenhouse gas emissions into the atmosphere, we’re gonna go to 800 to 1000 ppm, and there ain’t no model for which that is not an unmitigated human catastrophe for billions of people.
