‘Since around 1960, for mysterious reasons, trees have stopped responding to temperature increases in the same way they apparently did in previous centuries. If plotted on a chart, tree rings from 1960 forward appear to show declining temperatures, something that scientists know from thermometer readings is not accurate.
Most scientific papers have dealt with this problem by ending their charts in 1960 or by grafting modern thermometer measurements onto the historical reconstructions.’ source
Quite right too–what do mere trees know about AGW? Come to think of it, what do they know about research grant submissions? And academic ambitions? And tax bonanzas?
