Sentences with phrase «milankovitch cycle periods»

Of course, the pattern of season lengths would eventually repeat itself, with a period equal to the least common multiple of the three Milankovitch cycle periods.

Not exact matches

The second step involved calculating Earth's energy balance for this time period, using estimates of greenhouse gas concentrations extracted from air bubbles in ice cores, and incorporating astronomical factors, known as Milankovitch Cycles, that effect the planetary heat budget.

Re 92 and 105: First I just want to reitterate more generally what 105 said — Milankovitch cycles have had climate signals, in ice ages or otherwise, — well probably ever since the Moon formed, although the signal from times past will not always reach us, but I've read of evidence of Milankovitch precession cycle forcing of monsoons in lakes in Pangea (PS over geologic time the periods of some of the Milankovitch cycles have changed as the Moon recedes from the Earth due to tides).

Predicted changes in orbital forcing suggest that the next glacial period would begin at least 50,000 years from now, even in absence of human - made global warming (see Milankovitch cycles).

While Milankovitch forcing predicts that cyclic changes in the Earth's orbital parameters can be expressed in the glaciation record, additional explanations are necessary to explain which cycles are observed to be most important in the timing of glacial — interglacial periods.

It is very unlikely that the Milankovitch cycles can start or end an ice age (series of glacial periods):

For variability on a long time scale, the effect is generally constant over a short time period (such as Milankovitch cycles).

It's the same series of an initial forcing (change in insolation due to Milankovitch orbital cycles) being amplified by reinforcing feedbacks (change in albedo, change in temperature and partial pressure regulating both CO2 and H2O), but in reverse from an exit from a glacial period.

The Milankovitch cycles — the influence of astronomical cycles on the climate — give periodic dependences with periods up to 100,000 years.

In the natural cycle regarding long term natural climate change caused by Milankovitch cycles, at least for the past million years or so, the sensitivity response to changes is indicated to alter the global temperature by 6º Celsius between warm periods and glacial periods.

LIA is very brief period in relation to the Milankovitch Cycle.

With weather averaged out, with solar cycles averaged out, with ice ages and Milankovitch cycles averaged out, in geologic time, galactic cosmic ray flux * is * the driver of the great ice ages and hothouse periods in the Phanerozoic, with something of a 6C or 7C peak to peak temperature swing of * equatorial * ocean temperatures (from my eyeball measurement of a Veizer chart).

Do you think you can convince me that we aren't in a interglacial period that is getting a bit long in tooth, that the Milankovitch cycle that helps the glaciers grow by making northern hemisphere winters warmer and summers cooler isn't moving in the direction favorable to glaciation, and that the next once - per - thousand year volcanic eruption won't happen in this century, and it won't be the straw that breaks the camel's back by lowering the earth's temperature a couple degrees for a few years to mark the end of the Holocene?

Anyone studying climate after that period should be very aware of the Milankovitch cycles.

Some scientists think volcanoes may act in concert with Milankovitch cycles — repeating changes in the shape of earth's solar orbit, and the tilt and direction of its axis — to produce suddenly seesawing hot and cold periods.

Currently, we should be in a cooling period in the Milankovitch cycle, with the next ice age 30 - 40 thousand years away.

I propose that Westeros (or rather, the unnamed planet which contains Westeros and Essos and any other undiscovered continents in Game of Thrones; let's call it Westeros - world) experiences glacial cycles just like Earth, but the periods of the underlying Milankovitch cycles are much shorter — on the order of years to decades.

Mathematics suggests that there is absolutely no correlation between Milankovitch cycles and past glacial / warming periods.
