We see the curves rising at remarkable rates
we know it ties up with dates for human actvcities whwich would produce those rises,
we can trace the actual chemicals going into the stratosphere by looking for marker chemicals (specific isotopes).
You easily find evidence of wrming in worrying places, such as ice sheets, glaciers, dying corals and whatnot.
No we don't understand every nuance. Where we find that we didn't understand something, it tends to be worse than we thought.
There are several situation where a small change causes a "flip" which doesn't revese if we get temperature to fall to where they were. (For example where ice melts leaving dark earth, the dark earth warms up more. cf "albido".)
Some of those flips would be enormously consequential, for example if the "great gyre" of ocean currents changed course. Gulf stream, maybe soon.
I expect the effects to be bad and soon, and anyone who doesn't think in that direction has ulterior motives or is very dense.
I took a kid through Env Sci A level last year, so had to learn enough to teach it. It's compelling.
I do not think there's much point a tiddly country like the UK going faster than the ROW though, unless we can make energy cheaper.
It has to be a joint effort, and Trump amongst others is too selfish.
It's a factor in why we wouldn't see much life in the universe - advanced civisations probably wouldn't last very long. How long would you give Earth Inc? A few hundred years? That's nothing.
