I said it’s irrelevant w/rt predicting regional changes in precipitation because there are no spatiotemporal variables involved (meaning with respect to space and time).
Of course the thermodynamic processes denoted by the CC equation are always true, technically. But the equation itself tells you absolutely nothing about how precipitation will change in the PNW going forward. For reasons you should understand.
That was a nice pivot from telling me that the CC equation is irrelevant to climate science to pretending like I’m playing catchup to you.
Your second paragraph is the justification why we model climate change and why it is modeled with a wide variance of configurations. Otherwise we could just take our current precip and multiply it by 1.015 per degree C and be good.
I think the climate models have more skill than you give them credit for, but that’s probably not worth debating at this time.
Now we’re getting somewhere. Yes, this is (generally) correct. But the keyword is GLOBAL.
You can’t apply the same logic to individual regions. Because there will be spatiotemporal variability in general circulation(s)/weather patterns, convection/clouds/albedo, and all relevant transports/fluxes/conversions of sensible+differential heating.
So exactly how precipitation will change in the PNW, specifically, and at what time(s) of year, cannot be ascertained. Though predictions can be made with a low (but nonzero) degree of skill.
