Because of solar insolation, the system is not closed. In particular, we have a valve (CO2) controlling insolation and reflection. You would not argue that the effect of a Mylar sheet placed above a sunny swimming pool has to do with the

You seem to be arguing that, because the planetary mass of CO2 is smaller than that of water, CO2 changes cannot substantively affect water transport. So, I’d strongly suggest you should just read the NCA, because this argument is both ridi

The reference I offered summarizes the current state of knowledge about the linkages between climate change due to globally-rising CO2, and drought. The quote I gave tells a couple of specific links. The report itself offers plentiful anal

There are indeed causal links which play out differently from region to region. Here is the current best wisdom on links between global change and drought: https://nca2018.globalchange.gov/chapter/3/ It's a

This does indeed happen. For instance, evening winds in southern coastal CA will often blow out to sea ... perhaps in the SFBA it’s similar. But in this particular instance, it’s hard to be sure if that’s the explanation without knowing mo

Bias in what sense? There is overwhelming physical evidence that climate is changing ... it’s not really a “cabal” situation. Can you detect any evidence of any forces attempting to bias climate science? Perhaps you mean energy companies?

Some of this was familiar, but I also saw this: > In 1973, Saharon Shelah showed that the Whitehead problem ("is every abelian group A with Ext^1(A, Z) = 0 a free abelian group?") is independent of ZFC. (This is the same Shelah

OTOH, the example in the OP has somewhat the flavor of the hard problem you just sketched. The tree-based (RPN-esque) notation itself gets around much of the "perturbed program fails to compile" problem.

Good point. This character is a staple of many old novels and films -- Arthur Hailey's novel Hotel (1965, adapted as a movie) has such a detective, who is corrupt and mainly wants to extract bribes from any guest who breaks a rule.

Your comment is an example of the "middlebrow dismissal" [1] and overdone and uninformed skepticism that is prevalent on HN climate threads. There's no indication that the authors are cherry-picking their models but the comme

Could you name the climate model that predicted a "fiery wasteland"? What exactly does this mean? Also: as has been pointed out, in TFA and elsewhere in this thread, the authors of the linked study did not cherry-pick the models.
