The intensifying effects of warming temperatures on water shortages have been detected in remote northern New Mexico, where melting snowfall feeds one of the Southwest's most important rivers.

The underlying logic is sound: as sea ice melts, it exposes darker ocean water, which absorbs more of the sun's heat, causing the water temperatures to increase.

The Arctic is warming more than twice as fast as the rest of the planet, because as ice melts at the top of the world, there is less of it to reflect sunlight back into space, so more of it is absorbed by ocean waters; more absorbed sunlight means even warmer temperatures, which means more ice melt a circular process known as Arctic amplification.

Glacier speed also depends on bottom drag (which is a function of temperature and lubrication by melt water) and also stresses within the ice sheet / shelf as well.

Rising ocean waters and air temperatures are essentially putting ice in a vise grip of warming and speeding up melt.

Rising Seas: Warmer ocean water temperatures, the pumping of ground water, and melting of the polar ice sheets have added water to the oceans, contributing to sea level rise.

Before today's basic refrigerator could ever be born though, scientists had to tease apart the meaning of temperature, find a standard way to measure it, discover what it takes for water to freeze, and how ice melts.

Scientists agree that a doubling of atmospheric CO2 levels could result in temperature increases of between 1.5 and 4.5 °C, caused by rapid changes such as snow and ice melt, and the behaviour of clouds and water vapour.

The physical processes by which energy might be added into the glacier material include: (A) convection between the glacier surfaces and local surrounding atmosphere and water, (B) direct radiation onto the exposed surfaces of the material, (C) addition of material that is at a temperature higher than the melting temperature onto the top of the glacier (rain, say), (D) Sublimation of the ice directly into the atmosphere, and (E) conduction into the material from the contact areas between the glacier and surrounding solid material.

[1] CO2 absorbs IR, is the main GHG, human emissions are increasing its concentration in the atmosphere, raising temperatures globally; the second GHG, water vapor, exists in equilibrium with water / ice, would precipitate out if not for the CO2, so acts as a feedback; since the oceans cover so much of the planet, water is a large positive feedback; melting snow and ice as the atmosphere warms decreases albedo, another positive feedback, biased toward the poles, which gives larger polar warming than the global average; decreasing the temperature gradient from the equator to the poles is reducing the driving forces for the jetstream; the jetstream's meanders are increasing in amplitude and slowing, just like the lower Missippi River where its driving gradient decreases; the larger slower meanders increase the amplitude and duration of blocking highs, increasing drought and extreme temperatures — and 30,000 + Europeans and 5,000 plus Russians die, and the US corn crop, Russian wheat crop, and Aussie wildland fire protection fails — or extreme rainfall floods the US, France, Pakistan, Thailand (driving up prices for disk drives — hows that for unexpected adverse impacts from AGW?)

I suspect that what was happening was that there was mass loss, but there was also thermal expansion of the ice, as melt water drained down through the ice and froze, depositing its heat of fusion and raising the temperature.

Snowfall varies across the region, comprising less than 10 % of total precipitation in the south, to more than half in the north, with as much as two inches of water available in the snowpack at the beginning of spring melt in the northern reaches of the river basins.81 When this amount of snowmelt is combined with heavy rainfall, the resulting flooding can be widespread and catastrophic (see «Cedar Rapids: A Tale of Vulnerability and Response»).82 Historical observations indicate declines in the frequency of high magnitude snowfall years over much of the Midwest, 83 but an increase in lake effect snowfall.61 These divergent trends and their inverse relationships with air temperatures make overall projections of regional impacts of the associated snowmelt extremely difficult.
