Climate change is an interesting example. An example of a DIRT registry, would not be the question of "is climate change real". It's unclear what defines "real". Rather a registry could be a list of the average air temperature in a city over time.

Average air temperature according to whom? How do you verify the values, recorded ostensibly from sensors, were ever measured? How do you verify historical data for everything pre-2018?

Ground truth can be constrained statistically.

Don't take me wrong. I don't really see the value in inventing a truth bureaucracy that rewards participants in fake money. This dirt system is just silicon valley, in it's typical naivety, trying to reinvent propaganda.
