That is not how it works. At all. There are a multitude of ways atmospheric circulation could change to alter precipitation patterns worldwide, some of which would amplify extremes, others which would dampen them.
“Wet gets wetter, dry gets drier” is a myth perpetuated on social media by people who lack understanding of climate dynamics. It’s possible that will indeed be the outcome, but it’s also possible the inverse will be true. Or both could be true for limited periods of time. We can’t possibly know.
The mechanisms behind “wet gets wetter, dry gets drier” are some of the most established principles of climate science. There’s nearly a 100% chance that PNW rainy season precipitation in the next 30 years will be higher than the previous 30.
I agree that attributing < 10-20 year trends to climate change is dangerous (which is why I said in my post that I doubt you can attribute the recent wet springs to climate change), but over the longer term averages the trends predicted by the climate models will win out.
Beautiful morning on the weather deck. The landscape seems to already recovering from the harmful drenching just a matter of hours ago. The resilience of nature is truly astounding.
