Tree-ring evidence reveals recent cooling and glacier thickening in Central Asia as well as flat temperatures throughout the last 432 years.
Tree rings were the proxy used by Dr. Michael Mann to invent the orignal hockey stick graph.
Twenty years later, yet another reconstruction (1580 to 2012 AD) indicates modern warmth in Central Asia is not unusual in the context of the last 432 years.
In fact, there was a recent cooling period, in line with natural variability, that was accompanied by regional glacier mass gains.
