I saw this graph about the global temperature, it goes back for 2000 years.
How is it possible to measure temperature 2000 years back with such a precisionwith such a precision of like ~0.1 C?
The image from Reddit post but I'm not sure what'sI don't know the source of original data.
What tools are used to measure it?
