Sentences with phrase «small ice caps»

Earth today resides in a warm state with small ice caps, but geologic evidence suggests that the Neoproterozoic Earth, about 500 Myr ago, may have been frozen all the way down to the equator.

In this text, mountain glaciers exclude the large ice sheets of Greenland and Antarctica and the surrounding smaller ice caps.

Covering 1.59 million square miles (4.12 million square kilometers), this summer's sea ice shattered the previous record for the smallest ice cap of 2.05 million square miles (5.31 million square kilometers) in 2005 — a further loss of sea ice area equivalent to the states of California and Texas combined.

Consistent with observed changes in surface temperature, there has been an almost worldwide reduction in glacier and small ice cap (not including Antarctica and Greenland) mass and extent in the 20th century; snow cover has decreased in many regions of the Northern Hemisphere; sea ice extents have decreased in the Arctic, particularly in spring and summer (Chapter 4); the oceans are warming; and sea level is rising (Chapter 5).

The Antarctic Ice Sheet first formed as a small ice cap (maybe several) in the early Oligocene, but retreating and advancing many times until the Pliocene, when it came to occupy almost all of Antarctica.

And this is just one element in the sea level rise — small ice caps are melting faster, thermal expansion will increase in line with ocean heat content changes and Antarctic ice sheets are also losing mass.
