Disputed / Incorrect Graphs

2,000 Years – Incorrect Graph – The data in this graph should only extend to 1935, not 1980. Per “Correction to: A 2000-Year Global Temperature Reconstruction Based on Non-Tree Ring Proxies” by Craig Loehle, Ph.D. and J. Huston McCulloch: with the corrected dating, estimates only run from 16 AD to 1935 AD. A comment addressing the issue can be found here.

Falsified Graphs
