/sci/ - Science & Math

Stephen Jay Gould actually had an interesting essay about how surprisingly early in history the Earth was known to be round, and how modern flatheads are a relatively recent movement rooted in cultural revanchism and historical revisionism.

>Impossible. Science is observable, testable and repeatable. All they do is make observations and twist it to try and fit their sci-fi theory.
You are of course wrong, summerfriend. The CMB resulting from the Big Bang was predicted years and years before it was actually measured. And when it was eventually detected (no mean feat), the observations fit the predictions to a T.

Ice ages (technically, glacial maxima and minima) correspond very closely to Milankovitch cycles, which are periodic variations in the Earth's orbit that influence how much sunlight we get. Those have timescales of tens to hundreds of thousands of years, and right now we're in the cooling part of the cycle. And yet we're seeing rapid (century-scale) warming.

Additionally, the CO2 in the atmosphere is getting isotopically "lighter", which means that the CO2 being added is from organic matter (i.e. fossil fuels) rather than being released from the ocean or something. Because plants preferentially take up 12C over the rarer 13C, organic carbon is depleted in the heavier isotope relative to the background ratio.
