How do scientists explain the cause of the Ice Age(s)?

The ice core data rips this to shreds. Ice cores from Greenland and Antarctica have 450,000 years worth of annual ice layers. It is from this data that the link between the Milankovitch cycles and ice ages was first inferred. Here is the temp and CO2 data from the Vostok ice core: Notice first the time scale at the bottom. 400,000 years. During that time there have been 4 ice ages (4 valleys) that are evenly spaced. It is the even spacing of hot and cold periods that suggests a cyclical cause, most likely the Milankovitch cycles.

Actually, this isn't quite accurate. We are in an interglacial period. Take a look at this chart: source here: http://www.global-warming-and-the-climate.com/...rgument.htmYou will see that we are at a temperature peak right now (the y-intercept). The valleys in the chart represent the ice ages. It is because of warm ocean waters that push water vapor into the air. The moisture that falls as snow comes from warmer areas of the globe. This is why you see such a difference between snow accumulation on the coasts of Greenland (several feet a year) compared to the middle of Greenland (just a few inches a year). The warm, moist air hits the cold air on the continent and precipitates out. By the time it gets to the middle of Greenland there is hardly any moisture left. You also have to factor in the rate at which this energy is absorbed. Ice reflects this energy back into space while bare ground and liquid water absorb the energy.

It would really help if you would present evidence which would demonstrate that these interpretations are wrong. Simply making up a story is not a valid way to falsify scientific interpretations that are based on literal mountains of evidence.

And this evidence is . . .? And your interpretation is better because . . .?

How do mega floods produce these features?

It is also said that Mikey from the Life cereal commercials died when he ingested Pop Rocks and Pepsi. People say a lot of things. What matters is the evidence. Do you have any?

What type of formation could a mega flood not produce? How does a mega flood produce 400 foot thick chalk deposits made up of coccolithophores? How do mega floods create lake varves where the insect and leaf debris is sorted by minute differences in 14C? How do megafloods produce fossilized windswept sand dunes like those seen in the Cocconino sandstones in the Grand Canyon? How do megafloods produce incised gooseneck meanders like those seen here:

Based on what evidence?
