evidence: On its Earth Observatory web site, NASA published in the year 2000, the information they possessed about the Milankovitch Climate Theory, which was PROVED to be fact by core samples from the earth's seas. Climate Changes - warming and destructive weather - happen naturally from changes in earth's solar orbit, and the extent of earth's axis tilt. NOT from man-induced factors! [...] It was the year 1958, to be precise, when NASA first observed that changes in the solar orbit of the earth, along with alterations to the earth’s axial tilt, are both responsible for what climate scientists today have dubbed as "warming" (or "cooling," depending on their agenda). In no way, shape, or form are humans warming or cooling the planet by driving SUVs or eating beef, in other words. [...] Left to its own devices, the orbital arrangement our planet currently finds itself in would likely keep us in the current interglacial period (not a widespread ice age, not an ice-free world) we currently find ourselves in for another 50,000 years — a relatively quiet period of time from a Milankovich perspective. In other words, Milankovitch cycles cannot address rapid rises in temperatures that are currently being witnessed on human time scales — events occurring on time periods that represent a fraction of even the shortest Milankovitch cycle. The concern is what added effect humans are putting into the system on top of the more slowly varying orbital changes.
