Sentences with phrase «ice during colder periods»

Carved by earlier advances of ice during colder periods, the troughs enable warm, salty water to reach the undersides of glaciers, fueling their increasingly rapid retreat.

Not exact matches

The more intensive variations during glacial periods are due to the greater difference in temperature between the ice - covered polar regions and the Tropics, which produced a more dynamic exchange of warm and cold air masses.

This article will use the term ice age in the former, glaciological, sense: glacials for colder periods during ice ages and interglacials for the warmer periods.

Walter Starck noted that if only humans really were able to heat the globe, «and it helps to prevent another ice age, this would be the most fortunate thing that has happened to our species since we barely escaped extinction from an especially cold period during the last ice age some 75,000 years ago.»

Once a temperature threshold is breached, abrupt events follow due to amplifying feedbacks, even within a few years, examples being (1) freeze events which followed temperature peaks during past interglacial peaks due to influx of cold ice - melt water into the north Atlantic Ocean; (2) the Dansgaard — Oeschger warming events during the last glacial period; (3) the Younger dryas stadial freeze and the Laurentian stadial freeze.

During a glacial period (ice age) the oceans near both poles are much colder so the amount of heavy oxygen is very small.

This suggests that colder winter temperatures over the NH continents during portions of the 15th through the 17th centuries (sometimes called the Little Ice Age) and warmer temperatures during the 12th through 14th centuries (the putative Medieval Warm Period) may have been influenced by long term solar variations.»

The fact that the earth appears to have gone through huge changes in atmospheric CO2 concentration over geologic eras, while the estimated temps went from 12degC to 22 deg C regardless of «Snowball Earth» or «Cretaceous Hot House» with both hot and cold periods occurring during both high and low CO2 regimes and both with and without ice caps argues very strongly that we do not understand the climate mechanism at all.
