It's a guess. We only have maybe 150 years of temp data and much less
years of other data. In the history of the planet that is zip.



Not really. By drilling into the glacial ice, they measure the air coming
from the teeny little bubbles trapped in the ice, and are very good at
measuring the makeup of the atmosphere, for a LONG way back.

That doesn't tell us hardly anything. You can't even nail down within a
100 year period when that air was trapped, much less what the temp was
on July 24th that year. Or the year before. Or after.
