Seems particularly manipulative to only show the last 100 years. How about the last 1000 or 2000 years instead?

Temperature estimates over the past 2000 years using multiple proxy methods: https://en.wikipedia.org/wiki/Temperature_record_of_the_past...

But if they just show 2000 years, why would they cut off there? Seems manipulative too, we should definitely go back to at least 10,000 years.

To avoid cherry-picking, it should go back to the formation of the Earth.
