TBF you can also pretty know the temperature from thousands of years ago somehow accurately by analysing ice from the polar caps
Yeah but the original toot is only taking about measured temps, not proxy temps.
they have daily readings from cores?
Yearly. They look at slices generated by compressed layers of snowfall. Thick layer = cold year. They look at more stuff but that's roughly how it works.
edit: not sure why you're downvoted. It's a good question.
Also the composition of captured gasses dissolved in the ice help us see what the atmosphere was like back then
It's a really cool field to look into NGL

The herd acts in mysterious ways... one would have thought we left those practices in the R-site...
