All we need to do is figure out how to tilt the earth just a bit.
Ever see those political cartoons lampooning gas prices? Those SUVs are friggin' HUGE! If U.S. consumers buy just a few more thousand of those babies, North America will obvious become so heavy relative to Asia on the other side of the planet that the earth will lean toward the heavy side. Tilted earth = cooldown to counteract the "greenhouse effect". Problem solved.
How's that for junk science? Right up there with global warming "theories" based upon computer models that can't even get the weather right 2 or 3 days in advance, much less years or centuries.
The disposition of the continents would be a factor. Were they all on the equator, there may have been no ice age. Milankovitch worked out the correlations (long before computers) and gave a plausible explanation. It's not clear that the various tilts are enough in themselves to trigger an ice age; however, with a bit more cooling, it could happen. Stochastic® Resonance was invented (or at least invoked) to explain ice ages.

Maybe the ice got too heavy on one side and made it tilt after the fact!
Geologist Joe Kirschvink has combined both continental drift and slipping crust ideas to arrive at the theory that what we know as the continents of the Earth slid around en masse over a period of 15 million years. This took place after the supposed breakup of the alleged Pangea supercontinent, when there were two continental groups. North America was near the south pole, and rest of the landmasses were joined in Gondwanaland and stretched from pole to pole. Kirschvink used remanent magnetism in rock strata to determine that the whole crust turned counterclockwise (in the drawing) and left North America near its current latitude while Antarctica and Australia were jammed together near the equator. [ Earth magazine, June 1998, pp. 34-37 ] 90 million years ago an island in what we call the Arctic enjoyed weather similar to Georgia or Florida, despite not having budged much from its current relationship to the Earth's rotational axis.
The obvious problem with all gradualists "explanations" is obvious -- not all of the Arctic was glaciated, and some of the areas at the same latitude were downright pleasant. Meanwhile, during the summer, the Sun was hotter, meaning that the glaciation would have to accumulate basically in one year, because the summer heat would have been considerable and would have melted everything.The Earth's Changing OrbitIf the earth and the sun were the only bodies in the solar system, the earth's orbit would not change. However, the moon and the other planets are constantly pulling on the earth. The result is that the angle between the earth's axis and the plane of its orbit, the season at which the earth is closest to the sun, and the degree to which the earth's orbit is elongated all vary slowly over time. Right now, the elongation of the orbit (the eccentricity) is rather small -- about 1.7%. This results in the sun being about 7% brighter at the earth when it is closest, on January 4, than when it is most distant.

Twelve thousand years ago, when the glaciers of the last great ice age were melting, the eccentricity was a bit higher, about 2%. At the same time, the earth was closest to the sun in June, and most distant in January, so the sun was about 7 % brighter in June than it is today. At various times in the last million years, however, the eccentricity has been much higher -- as much as 6%, which would make the sun almost 25% brighter at perihelion (when the earth is closest to the sun) than at aphelion (when the earth is farthest from the sun). During the interglacial before the last ice age, about 125,000 years ago, the eccentricity was about 4%. The times of largest eccentricity tend to be about 100,000 years apart.
How could two Hollywood animated movies be responsible for tilting earth?
Especially movies that are so cute and cuddly.
These so called experts continue to ignore the impact that Mikkos Cassadine's evil weather machine had.
We need Washington to pass a law!
This is really simple stuff. It’s as obvious as day and night, as are the impacts of variations in solar radiation (sunspot cycles), ocean currents, etc. But for some reason all those Great Scientists serving on the U.N. Intergovernmental Panel on Climate Change don’t seem to (care to) grasp it. Maybe we need to purge our universities and get back to teaching real science again instead of Marxist P.C.
