A new study produced by a University of Wisconsin-Madison geoscientist and Northwestern astrophysicist presents an explanation of the fluctuations of the earth’s temperatures that global warming alarmists are going to make sure to bury: The cycle of changes in the climate over the millennia is a result of changes in the amount of solar radiation, in part caused by small changes in the orbits of Earth and Mars.
While the theory that solar radiation is the most significant factor determining global temperatures is anything but new, the team of scientists have reportedly tied the phenomenon to planetary orbits in a more concrete manner than previous studies.
In an article summarizing the scientists’ findings, which were originally published this week in the journal Nature, the University of Wisconsin-Madison notes that the study “provides the first hard proof for what scientists call the ‘chaotic solar system,’ a theory proposed in 1989 to account for small variations in the present conditions of the solar system.” Those variations over millions of years “produce big changes in our planet’s climate.”
Not only does the new discovery promise to provide a better understanding of “the mechanics of the solar system,” but also “a better understanding of the link between orbital variations and climate change over geologic time scales.”

Over the ages, the subtle variations in the orbits of Earth and Mars, the scientists theorize, have impacted the amount of Earth’s exposure to solar radiation and thus led to shifts in global temperatures and impacting the pattern of Earth’s ice ages.
“The impact of astronomical cycles on climate can be quite large,” explains Meyers, noting as an example the pacing of the Earth’s ice ages, which have been reliably matched to periodic changes in the shape of Earth’s orbit, and the tilt of our planet on its axis.
