Previous research suggested that rapidly warming air and sea temperatures — which melt sea ice — might cause their numbers to plummet by as much as 19 % by 2100.

The Fourth Assessment Report finds that «Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising mean sea level.

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

Warming air temperatures, melting ice, and shifting currents are totally altering the ocean ecosystem, affecting the people, plants, and animals that call it home.

Glaciers and ice caps in Arctic Canada are continuing to lose mass at a rate that has been increasing since 1987, reflecting a trend towards warmer summer air temperatures and longer melt seasons.

Also at New York Times (though what to make of «scientists said the ice sheet was not melting because of warmer air temperatures, but rather because of the relatively warm water, which is naturally occurring, from the ocean depths»...?)

But observations from recent years support the idea that the melting ice is a key factor in shaping the persistent pattern of warm temperatures over the Arctic that displaces bitter cold air toward North America and especially Eurasia, says conference co-chair Judah Cohen, a climate scientist at the Massachusetts Institute of Technology.

The Fourth Assessment Report finds that «Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising mean sea level.

What is unusual is the amount of melting so far in the Antarctic, spurred by warm air temperatures and shifting winds.

At the end of the day, the discussion about a single calendar year obscures the more important long - term trend of warming air temperatures, warming and acidifying oceans along with melting ice sheets, all of which are hallmarks of manmade global warming.

(1) there is established scientific concern over warming of the climate system based upon evidence from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level;

And the thinner the ice, the easier it is actually to move it by winds, and the easier it is to be melted by the underneath warmer ocean and above surface air temperature.

Significant surface melting due to warm air temperatures created melt ponds that acted like wedges; they deepened the crevasses and eventually caused the shelf to splinter.

This value of 375 CO2 - e is the actual forcing that is currently acting to warm the oceans, melt ice, and cause gradual upwards changes in average air temperature.

Sea level is rising, primarily in response to a warming planet, through thermal expansion of the oceans, and also via the loss of land ice as ocean and air temperatures increase, melting ice and speeding the flow of non-floating ice to form floating icebergs.

«The top of the glacier is melting away as a result of decades of steadily increasing air temperatures, while its underside is compromised by currents carrying warmer ocean water, and the glacier is now breaking away into bits and pieces and retreating into deeper ground.»

Increased surface melting, loss of ice shelves, and reduction of summer and autumn sea ice around the Antarctic and Greenland continents during the warmest interglacials would have a year - round effect on temperature, because the increased area of open water has its largest impact on surface air temperature in the cool seasons.

As you'll be well aware, surface air temperatures can easily change by 10 C within a day, for large bodies of ice to melt, or sea water to warm would take centuries.

The average surface air temperature for the year ending September 2017 is the 2nd warmest since 1900; however, cooler spring and summer temperatures contributed to a rebound in snow cover in the Eurasian Arctic, slower summer sea ice loss, and below - average melt extent for the Greenland ice sheet.

Warming air and ocean temperatures increase glacier ice melt.

In July, the Arctic Dipole Anomaly (DA) pattern that was dominant in June (which promotes clear skies, warm air temperatures, and winds that push ice away from coastal areas and encourages melt) was replaced by low sea level pressure (SLP) over the Arctic Ocean, leading to ice divergence (ice extent «spreading out») and cooler temperatures.

«In the past decade, as air temperatures have warmed, surface melt has increased dramatically,» says the report's lead author, Romain Millan, a graduate researcher in the Earth system science department at the University of California, Irvine.

Quigley: «The ice sheet and gas changes tend to follow temperature change, because a warmer planet melts ice and drives gases into the air.

Warmer air means more melting, but moister air means more precipitation and therefore, where the temperature is right, more snowfall.
