I looked at your NOAA link. I could be mistaken, but I think it said the snow cover extent increased.

Ie was there snow on the ground in a given area. Snow that melts come spring.

This isn’t ice. Is there something in your link that suggests ice is growing? The sea ice portion showed it to be shrinking.

You’re claiming new glaciers are forming somewhere, basically.

Your timeline of the Maunder minimum is completely wrong. This doesn’t lend confidence to your interpretation of the NASA report: https://en.m.wikipedia.org/wiki/Maunder_Minimum
