Hockey sticks beware – dendro rulz!Richard Treadgold | July 14, 2012
A new study shows modern temperatures are not unprecedented and disproves an important part of Mann’s “hockey stick” paper of 1999.
Orbital forcing of tree-ring data, J. Esper et al., says:
“… large-scale near-surface air-temperature reconstructions [specifically the hockey stick] relying on tree-ring data may underestimate pre-instrumental temperatures including warmth during Medieval and Roman times.”
This is beautiful.
