Now let's see what Mann et al did with this data. All of the 20th century values of varve thickness, X-ray density etc go up like crazy with the agricultural and construction activities as shown below for 2 of the 4 series (the other two are similar). Instead of using the climatic interpretation of the data described by Tiljander et al, Mann correlates the increases in varve thickness and changes in density and color, originating from local construction and farming, to world climate.
By flipping the data opposite to the interpretation of Tiljander et al, Mann shows the Little Ice Age in Finland as being warmer than the MWP, 100% opposite to the interpretation of the authors and the paleoclimate evidence. The flipping is done because the increase in varve thickness due to construction and agricultural activities is interpreted by Mann et al as a "nonlocal statistical relationship" or "teleconnection" to world climate.

A more convincing example of spurious regression in "peer reviewed" literature will be hard to find.

Psychologist Jonathan Haidt studies the five moral values that form the basis of our political choices, whether we're left, right or center. In this eye-opening talk, he pinpoints the moral values that liberals and conservatives tend to honor most.

Reuben's tube is a classic way to demonstrate the concept of a standing wave. Pump some flammable gas into one side of a tube, and attach a speaker to the other side, and watch what happens to the columns of flames that issue from small holes along the top.
