The science is settled? Apparently not as a group of German scientists have found that virtually all of the temperature change associated with “climate change” is caused by natural variations called the de Vries cycle, and that the globe is now on a cooling trend that will last until about 2100:
“Due to the de Vries cycle, the global temperature will drop until 2100 to a value corresponding to the ‘little ice age’ of 1870,” write German scientists Horst-Joachim Luedecke and Carl-Otto Weiss of the European Institute for Climate and Energy.
Researchers used historical temperature data and data from cave stalagmites to show a 200-year solar cycle, called the de Vries cycle.
They also factored into their work a well-established 65-year Atlantic and Pacific Ocean oscillation cycle. Global warming that has occurred since 1870 can be attributed almost entirely to both these factors, the scientists argue.
According to the scientists, the oft-cited “stagnation” in rising global temperatures over the last 15 years is due to the Atlantic and Pacific Ocean oscillation cycle, which lasts about 65 years. Ocean oscillation is past its “maximum,” leading to small decreases in global temperature.
The de Vries solar cycle is currently at its “maximum,” explaining why temperatures have risen since 1870, but leveled off after 1998. However, this means that as solar activity starts to decrease, global temperatures will follow.
“Through [the de Vries solar cycle’s] influence the temperature will decrease until 2100 to a value like the one of the last ‘Little Ice Age’ 1870,” the scientists wrote.
I wonder how long until the warmists start attacking these scientists as deniers, demanding that they pay their due penance to The Concensus™.
