"As regular readers know, a battle over global warming hysteria is raging among scientists, and the alarmists are consistently getting the worst of it. German scientists Horst-Joachim Lüdecke, Alexander Hempelmann and Carl Otto Weiss have published two influential studies in the European Geophysical Union journal. The first, published in 2013, examined the past 250 years of climate history. The second, published earlier this year, extended the research through the past 2,500 years.

Their findings are consistent with the main currents of modern climate science (as opposed to climate politics):

The analysis of the past 2500 years involved data from tree rings, sediment cores, stalagmites, etc. A plot of the data yields a climate operating with cyclic behavior.

Compared to the maxima and minima of the past, the current minima and maxima show that there is nothing unusual happening today. The scientists say today’s temperature changes are within the normal range. The German authors write: “Especially the 20th century shows nothing out of the ordinary.”

For better or worse, these scientists argue that global cooling is likely during the next 60 years:"
