Bundle Up! German scientists predict a century of global cooling
Two German scientists, Horst-Joachin Luedecke and Carl-Otto Weiss of the European Institute for Climate and Energy, say that "two naturally occurring climate cycles will combine to lower global temperatures during the next century." They added, "by the year 2100, temperatures on this planet will plunge to levels seen at the end of the 'Little Ice Age' in 1870." These researchers used historical data detailing temperatures as well as cave stalagmites to show a recurring 200-year solar cycle called the DeVries Cycle.
