Heres some for the last 500 Million years.
We are in a cool period atm, but getting warmer.
From what I can find, it was the coolest about 20,000 years ago.
It slowly warmed up again until about 10,000 years ago it was fractionally warmer than now.
Since then its slowly cooled down slightly, until recent times when its started to warm up again.
Its approching levels similar to about 11,000 years ago, and before that, about 5 million years ago.
Some 55 million years ago it was about 14C warmer than now.
The ice caps formed about 35 million years ago, as it cooled down.
In the grand scheme, we are still cooler than most of the life of the earth.
However, in recent history, its about the warmest its been in the last 12,000 years.
