A list of dozens of paleoclimate studies using various temperature proxies and methods in affirmation of Michael Mann's hockey stick result, which shows strong recent hemispheric and global warming.

Paleotemperature Hockey Sticks

This is a list of paleoclimate studies [2–63] that use a variety of temperature proxies and methodologies in affirmation of Michael Mann's hockey stick result [1], which shows strong recent hemispheric and global warming. The last column provides an exemplary figure from each paper.

The original MBH98 paper [1] has so far been cited 1200+ times (Web of Science).

N.B. For the original text list without hyperlinks or figures, go here. It's still being updated.

What do paleotemperature studies tell us in general?
