How many times before 1880 was it as hot as now?

That's an excellent question.

During the last 10,000 years it's been as warm as today - or warmer - during:

* The Medieval Warm Period.

* The Roman Warm period.

* The Minoan Warm Period.

* And two long periods known as the Holocene Climate Optimums.

That takes us back to the last Ice Age. However: millions of years ago the world was on average much warmer - by 5 degrees C or so.
