Climate Change Not Human Induced: Earth’s Wobble Causing Drastic Climate Changes (Picture, Video)
Is it the Earth’s wobble that is responsible for all of our global warming debates?! Can it be completely ruled out as a major contributor? Climate experts and biologists led by Jan van Dam at the University of Utrecht in the Netherlands, overlaid a picture of species emergence and extinction with changes that occur in Earth’s orbit and axis. The Earth’s orbit is not a perfect circle: it is slightly elliptical, and the ellipticality itself goes through cycles of change that span roughly 100,000 and 400,000 years. Its axis, likewise, is not perfectly perpendicular but has a slight wobble, rather like a poorly-balanced child’s top, which goes through cycles of 21,000 years. In addition, the axis, as schoolbooks tell us, is also tilted, and this tilt also varies in a cycle of 41,000 years. These three shifts in Earth’s pattern of movement are relatively minor compared with those of other planets. But they can greatly influence the amount of radiation — heat and light — which Earth receives from the Sun. The effect can be amplified, causing global cooling, affecting precipitation patterns and even creating Ice Ages in higher latitudes, when two or all the cycles peak together. http://www.physorg.com/news79791441.html
