Average world wide temperature.
> Modern human civilization, with its permanent agriculture and settlements, has developed over just the past 10,000 years or so. The period has generally been one of low temperatures and relative global (if not regional) climate stability. Compared to most of Earth’s history, today is unusually cold; we now live in what geologists call an interglacial—a period between glaciations of an ice age. But as greenhouse-gas emissions warm Earth’s climate, it's possible our planet has seen its last glaciation for a long time.
Unfortunately it makes it that much harder to fix the problem. Now we have to fix the problem and convince the deniers that it's a problem . Which is close to impossible since the more evidence they see the more they will try to normalize it.
I'm not worried because earth and life will be fine despite our trashing the planet. However to claim that things are extraordinary discounts historical records, even back a few million years.
