000-year cycle over the last 8 cycles. Richard A. Muller and Gordon J. MacDonald and others have pointed out that those calculations are for a two-dimensional orbit of Earth but the three-dimensional orbit also has a 100 thousand year cycle of orbital inclination. They proposed that these...

Ice ages and sea levels are closely linked, as water contained in glaciers is primarily derived from the sea, locking up vast quantities of water on landmasses and lowering sea levels. During the coldest phase of the LGM there was a large change in the global hydrologic cycle and sea levels...
The numbers for 800,000 years would be similar, based on a graph, from ice core data going back that far. The result is that the planet is warming at least 10 times faster than when it came out of the last ice age. It took about 10,000 years to warm by about 5 C, with temps...
The IR clean-out at the end of each SAR cycle was carried out at 325 °C for 200 s. The first 2 s of the post-IR IRSL signal minus a background estimated from the last 50 s was used for dose calculation. It is well-known that quartz OSL from Chinese loess is dominated by the...
These were mostly attempts at “glacial inception”, that is, starting an ice age. But we also saw a simulation of the last 120 kyrs which attempted to model a complete ice age cycle including the last termination. As we saw, there were lots of limitations.. ...
1) is a very critical component of the Arctic system that responds sensitively to changes in atmospheric circulation, incoming radiation, atmospheric and oceanic heat fluxes, as well as the hydrological cycle1, 2. Ice significantly reduces the heat flux between ocean and atmosphere; through its ...

For the last half of the 20th Century, as the atmosphere warmed, the hydrological cycle accelerated and there was more precipitation in the Southern Ocean surrounding Antarctica. This increased precipitation, mostly in the form of snow, stabilized the upper ocean and insulated it from the ocean he...
