Sentences with phrase «increased glaciation»

The Intergovernmental Panel on Climate Change Third Assessment Report considered the timing and areas affected by the LIA suggested largely independent regional climate changes, rather than a globally synchronous increased glaciation.

They were a cold adapted people and endured severe climate fluctuations, including several periods of increased glaciation throughout their existence.

It is evidence of increasing glaciation that results from expanding glaciers.

Not exact matches

Many aspects of this extreme glaciation remain uncertain, but it is widely thought that the breakup of the supercontinent Rodinia resulted in increased river discharge into the ocean.

These Equations, IF CORRECT, will predict the commencement of glaciation in Antarctica, and the progressive increase in Glaciation as Surface Pressures decrease, and Surface Temperatures decrease with elapsed time in million year iglaciation in Antarctica, and the progressive increase in Glaciation as Surface Pressures decrease, and Surface Temperatures decrease with elapsed time in million year iGlaciation as Surface Pressures decrease, and Surface Temperatures decrease with elapsed time in million year increments.

This chemical weathering process is too slow to damp out shorter - term fluctuations, and there are some complexities — glaciation can enhance the mechanical erosion that provides surface area for chemical weathering (some of which may be realized after a time delay — ie when the subsequent warming occurs — dramatically snow in a Snowball Earth scenario, where the frigid conditions essentially shut down all chemical weathering, allowing CO2 to build up to the point where it thaws the equatorial region, at which point runaway albedo feedback drives the Earth into a carbonic acid sauna, which ends via rapid carbonate rock formation), while lower sea level may increase the oxidation of organic C in sediments but also provide more land surface for erosion... etc..

Increases and decreases in glaciation during the Pennsylvanian resulted in sea level fluctuations that can be seen in the rocks as striped patterns of alternating shale and coal layers.

It is to be noted here that there is no necessary contradiction between forecast expectations of (a) some renewed (or continuation of) slight cooling of world climate for a few decades to come, e.g., from volcanic or solar activity variations; (b) an abrupt warming due to the effect of increasing carbon dioxide, lasting some centuries until fossil fuels are exhausted and a while thereafter; and this followed in turn by (c) a glaciation lasting (like the previous ones) for many thousands of years.»

Here we propose that increasing variablility within the past million yearsmay indicate that the climate system was approaching a second climate bifurcation point, after which it would transition again to a new stable state characterized by permanent mid-latitude Northern Hemisphere glaciation.

[The reason the Pliocene ended and made way for the Pleistocene increased polar glaciations could paradoxically also lie in this same strengthening of the MOC.

I.e., The glaciations were not initiated by CO2, but they were exacerbated by feedbacks that increased CO2.

predict the start of the next glaciation — or does it now predict ever - increasing rises in surface temperatures, so we had all better redirect our efforts to cost - effective amelioration?

The encroachment of increases in desert terrain around the fringes of the equatorial region is expected to show increases as the warming process reaches its «peak», before the «turn» back to a «glaciation dip».

For instance during glaciation there have been influenced by two causes: cooling surface waters dissolve more CO2 from atmosphere and a colder climate makes CO2 emitting from biosphere to increase, in which the dissolving of CO2 to sea surface wins the emission of CO2 from biosphere to atmosphere.

Add equivalent atmosphere and oceans to the Moon, and things would be downright toasty (a least until clouds and glaciation take hold and increase the Moon's albedo).

in addition another thought they do not bring up is under sea volcanic activity may heat up the oceans, increasing the amounts of water vapor put into the atmosphere which could result in more snowfall and eventual glaciation.

Since decreased solar luminosity at that time only partially offset increased radiative forcing from CO2, some other factor needs to be considered to explain the glaciation.»

They write, «If this correction is valid throughout the last glaciation the CO2 deglacial increase may have started simultaneously or even with a lead of the CO2 rise over Antarctic temperature.»

In a paper «Global warming preceded by increasing carbon dioxide concentrations during the last deglaciation», Shakun et al. (Nature 2012) contend that rising temperature at the end of the last Pleistocene glaciation were preceded by increasing atmospheric CO2.

So the ice melted before the CO2 increased I picked this up surfing the internt: «Glaciation For a number of reasons, the volume of glacial ice near the poles waxes and wanes over time.

The increased CO2 moderated the climate change, preventing full - scale glaciation, but nevertheless was insufficient to prevent some cooling (until the Industrial Revolution, of course).

What the clueless folks you are trying to reach actually need to know is that each decade is warmer than the last, at a rate near 2 degrees Celsius per century, which might well increase, and for comparison the difference between Ice Age glaciation and the climate we like is about 6 degrees Celsius.

So, if we really do get such increase in severity, it will be a sign of imminent glaciation.
