Glaciers in a sentence

Decline in thickness of glaciers worldwide over the past half-century Glaciers Glaciers are considered among the most sensitive indicators of climate change. citation Their size is determined by a mass balance between snow input and melt output.

Montana’s glaciers have also been melting rapidly, with the EPA saying that several glaciers are likely to disappear by 2030 if no change is made.

By examining the differences in the surface elevation of glaciers at different points in time, we were able to measure how quickly glaciers across the region have thinned over the past five decades.

Though glaciers seem far removed from individuals’ daily lives, the impact of climate change can be felt everywhere and glaciers prove to be one of the most poignant and obvious symbols of such changes worldwide, said Jackson.

In South America, glaciers are crucial for water supply—in some towns, including Huaraz in Peru, more than 85% of drinking water comes from glaciers during times of drought.

Most previous research on the underwater melting of glaciers relied on theoretical modeling, measuring conditions near the glaciers and then applying theory to predict melt rates.

The albedo effect lessened because of less snow and glaciers, as well as dirty soot on snow and glaciers.

The glaciers are responding to the warming of the climate and even if the warming would suddenly stop, the glaciers would still continue to lose volume.

The melting water stratifies the ocean column, with cold fresh water trapped at the surface and warmer water sitting below Then, the lower layer melts glaciers and creates still more melt water — not to mention rising seas as glaciers lose mass.

Fleming (2000), 89–90 High levels of precipitation cause the glaciers to descend to permafrost levels in some areas whereas in other, more arid regions, glaciers remain above about the convert level.

Glaciers and ice sheets Ice sheets and glaciers are flowing ice masses that rest on solid land.

Hanging glaciers (i.e. glaciers perched on steep slopes) often discharge themselves over steep rock-faces, the snout breaking off at intervals.

Here, huge and highly erosive pre-Wisconsinian glaciers excavated the bedrock valley floor, and much smaller Wisconsinian glaciers deposited glacial debris.

Ongoing research is showing that while glaciers tend to decrease mountain size, in some areas, glaciers can actually reduce the rate of erosion, acting as a glacial armour.

Some moraine types are known only from ancient glaciers, while medial moraines of valley glaciers are poorly preserved and difficult to distinguish after the retreat or melting of the glacier.

The easternmost portion of the state was scoured by Ice Age glaciers ; the Dissected Till Plains were left after the glaciers retreated.

The largest glaciers, as e.g. the Plomo glacier and the Horcones glaciers do not even reach 10 km in length and have an only insignificant ice thickness.

These include the Tasman and Murchison Glaciers to the east of the mountain and the smaller Hooker and Mueller Glaciers to its south.

These labours resulted, in 1840, in the publication of his work in two volumes entitled Etudes sur les glaciers ("Studies on Glaciers").

The Sherwin glaciers were the largest, filling Yosemite and other valleys, while later stages produced much smaller glaciers.
