is not the same as saying that global warming is happening and that scientists are >90% certain that it is caused by humans

to translate this from 'scientist speak' to 'non-scientist speak'- there is absolutely no question about this- if it makes you feel better, colloqually, then yes. 100% fact.

but scientists don't speak in absolutes - which is why its usually very difficult to translate this to someone who doesn't understand the core principles of scientific rationale.
you always allow for the possibility of a) being wrong or b) a better explanation coming along
so....there is a less than 5% chance that global warming is caused by something else *other* than human activity
shit, maybe the sun has moved closer!
