The effects of glacier retreat would become evident during the dry season, particularly in the west where glacial melt is more important to the river systems.

Global warming must be the primary cause of glacier retreat, which is occurring on a global scale, but observed rapid melt rates suggest that other factors may be involved.

Researchers have already identified evidence of glacier retreat in the West Antarctic and warned that bodies of ice massive enough together to raise global sea levels by three metres could — thanks to global warming as a consequence of fossil fuel combustion — be increasingly unstable.

Two new studies by researchers at the University of California, Irvine and NASA have found the fastest ongoing rates of glacier retreat ever observed in West Antarctica and offer an unprecedented look at ice melting on the floating undersides of glaciers.

Records of glacier retreat go back much further than the «last ten years» even in Greenland.

This can be affected by warming temperatures, but also by changes in snowfall, increases in solar radiation absorption due to a decrease in cloud cover, and increases in the water vapor content of air near the earth's surface.2, 14,15,16,17 In Cordillera Blanca, Peru, for example, one study of glacier retreat between 1930 and 1950 linked the retreat to a decline in cloud cover and precipitation.18

A good example is the report of glaciers retreating.

This short - term increase in runoff is interpreted as the consequence of glacier retreat, but in the long term there will be a reduction in water supply as the glaciers shrink beyond a critical limit (Jansson et al., 2003).

According to a recently published paper in the journal Science, (Cook et al., 2016, «Ocean forcing of glacier retreat in the western Antarctic Peninsula»), between 1945 and 2009 the mean ocean temperature warmed at depths of 150 to 400 meters for about 3 / 4ths of the waters surrounding the western Antarctic Peninsula (AP).

Pachauri, who led the compilation of some 2,000 of the world's top climate scientists for 13 years, worked to tighten up the credibility of the reports that guide policymakers and survived a scandal five years ago over exaggerated claims about the speed of glaciers retreating.

These methods include inference of surface temperature change from vertical temperature profiles in the ground (bore holes) at many sites around the world, rate of glacier retreat at many locations, and studies by several groups of the effect of urban and other local human influences on the global temperature record.

The analysis found three trends: 63 percent of glaciers retreated from 1974 to 1990, when it was warmer; 72 percent advanced from 1990 to 2000, when it was cooler; and 58 percent advanced from 2000 to 2010, a period that experienced phases of warming and cooling.
