Sorry, you post nothing but nonsense in every thread you're in. See ya.Ever heard of ice cores?The world's average temperature has been getting hotter unnaturally since the industrial revolution.
How was the global average temperature measured in the 18th Century?
Determining the temperature in Africa, or any other area largely unknown to 18th Century science, from ice cores taken from the poles is done by extrapolation, not measurement.
I asked how it is measured.
I accept your surrender.
