New Paper: China temperatures warmer during the 1700s, linked to solar, volcanic, and AMO/PDO forcing. Which is exactly what we have been saying for a long time. It is a cycle. This is not an attack on the right renewables. We should be developing the most efficient energy sources like thorium or future solar because it is the right thing to do, not because of a manufactured "we are all going to die" scare.

A new 368-year tree ring temperature reconstruction has established that regional (China) summer temperatures were warmer than they are now (2012) during the mid-1600s and early 1700s, and that the temperature variations can be linked to variations in solar activity, volcanic forcing (cooling), and natural oceanic-atmospheric oscillations (AMO/PDO).

The authors are intent on pointing out that it is “noteworthy that 20th century warming was not very obvious in our reconstruction.”  This “noteworthy” finding is mentioned four different times in the paper.

The lack of a conspicuous 20th century warming — and the warmer periods during the 1600s and 1700s — are clearly shown in the summer temperature graph below:
