Sentences with phrase «when obliquity»

Huybers (Quaternary Science Reviews, 26, 37) has proposed a simple model in which deglaciation is triggered when the obliquity cycle is high, and when ice mass is sufficiently high.

I have claimed the Holocene ended in 1300ad, the start of the LIA sequence, when obliquity fell past 23.5 deg.

Huybers (Quaternary Science Reviews, 26, 37) has proposed a simple model in which deglaciation is triggered when the obliquity cycle is high, and when ice mass is sufficiently high.

Not exact matches

Vetoretti and Peltier (2004) found that glacial inceptions can be caused either by a strong obliquity forcing or by a combination of eccentricity - precession forcing and low CO2 values, which is in line with results from Berger and Loutre (2001) who found that CO2 is important during times like the MIS - 11, when the insolation variations are too small to drive glacial - interglacial cycles.

He doesn't understand glaciations, as he uses 65 ° N summer insolation, when glaciations clearly respond to obliquity, as we saw in the first article of the series.

It could only do so when precession modulation and eccentricity also provided a coincident warming impulse; this happens about every 2 or 3 obliquity cycles.

We already observed that problem when reviewing the Dansgaard - Oeschger cycle, where the oscillations depend on a set of conditions in sea - level, temperatures, and obliquity, to become perceptible.

While the earth does not exit an Ice Age every 41k years according to the obliquity cycle when it achieves it's maximum angle of > 24 degrees, over the 10 recorded Ice Age events, EVERY TIME WITHOUT FAIL as obliquity drops below 23.5 % an Ice Age STARTS.

As might occur, say, when the Earth's orbit is maximally elliptical, obliquity is minimal (less tilt, cooler summers) and the Northern Hemisphere's summer occurs when the Earth is furthest from the sun.
