How many have access to Michael Mann's data? And why would he consider it proprietary if it agrees with published data sets?

Mann's? Probably a handful. I know a different handful of folks spread across the world (don't feel like counting how many dozens of people) who contributed to the other proxies in the PAGES 2k network. Who found the same hockey stick.

If anything, switching to proxies vs the instrumental record (which I originally thought was the object of your musings) spreads out the network of "gatekeepers" dramatically - every expedition to get an ice core, every tree ring group, every coral study, etc.

Does that make sense, Scott? I worry your followers only saw your tweet, and so missed the fact that Mann and a handful of others aren't the sole gatekeepers of data (reconstructions, really) on whether current temps are the highest in at least the past millennium.

How much human “correction” to the data is there?

But that's a different question, right? I mean, I'd like to discuss that, too. But please don't abandon the gatekeeper/trust thread entirely. When you do science, there's a TON of corrections ;) Calibration, bias subtraction, it's the bulk of a paper's data section.

What percent of the 97% of scientists backing climate change personally collected measurements from each of the sources/methods worldwide? (This discussion is not optimized for Twitter.)

A tiny fraction - not a lot. But there's enough (~100s), spread across the globe, independent institutions, etc, that it's not "faith" or "trust" that these ~100s of independent folks aren't being careful with their measurements. (W.r.t. Twitter, agreed!)

All of those hundreds have personally gathered worldwide temperature data from each source? (Literally traveling to each?)

??? No one person collects every proxy. Different teams go to different sources. So we have ~100s of people who can vouch for ~100s of proxies, but not one person who can vouch for them all. Does that make sense?

Got it. And how many of those measuring sites have more than one device in place (of a different type) to double-check the main device?

They've got quality control, for sure. There's all sorts of checks you can make. I'm interested in taking a deeper dive into that now, thanks. But I'm glad we finally hit bedrock regarding gatekeepers and faith.
