It's not feasible for any individual to go out there and verify every scientific claim for themselves but I'm satisfied that scientists are out there doing so all the time. No doubt many of the more specific hypotheses around exact sensitivities or likely glacial melting patterns will turn out to be overturned and replaced with better ones. The economic forecasts of the effects of warming temperatures/ higher sea levels I definitely take with a large grain of salt, and there may well be cases it makes more sense to wait until better technologies are developed before going all out with what we have now, but we've known enough for quite long enough (multiple decades) that it's absurd to continue claiming we should do nothing at all about reducing emissions just in case current scientific understanding gets overturned.
