Ice conditions in August 1958 were too heavy at the Pole for the Skate to surface, as they were for the Nautilus some days earlier.

The team, which Marc led and provided the logistical support for, deployed from Resolute to Nord Greenland before setting up a rustic field camp on the sea ice for six days, during which time we mechanically drilled the ice to measure thickness, measuring snow depth in a grid pattern along the flight lines as well as dragging instruments along the surface that produced the same measurements for comparison to the airborne data.

Ocean & surface temperature measurements continue to climb, even though ALL the CAUSES of Ice Ages continue to this day.

Top: The total daily contribution to the surface mass balance from the entire ice sheet (blue line, Gt / day).

For several days this month, Greenland's surface ice cover melted over a larger area than at any time in more than 30 years of satellite observations.

The variability is due to day - to - day variations in temperature, strength of the surface - based temperature inversion, atmospheric humidity, and the presence of «diamond dust» (near - surface ice crystals).

«The Greenland ice sheet, which is up to 3000 + metres thick, is not «melting away», did not «melt in four days», it is not «melting fast», and Greenland did not «lose 97 per cent of its surface ice layer».»

Just weeks later, Greenland was grabbing headlines: 97 percent of the surface of its massive ice sheet had melted to slush, with most of the melt occurring in just four days.

Although the surface of the Greenland ice sheet can react rapidly to day - to - day weather changes, the melting of the volume of ice below is actually an inert process — driven by climatic changes instead of single meteorological events.

Second, and less important but still rather spectacular, was the melting of virtually every square inch of the surface of this ice sheet over a short period of a few days during the hottest part of the summer, a phenomenon observed every few hundred years but nevertheless an ominous event considering that it happened just as the aforementioned record ice mass loss was being observed and measured.

If you think about it and if they «are» right about both the causes and the effects (melting ice caps, raising sea levels — e.g. increased ocean surface worldwide, increased surface temperatures on land and at sea and erratic excesses in weather) then the results may well be an eventual drastic swing the other day as we see increases in reflection, evaporation and conversion of «greenhouse» gases back into inert forms!

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 observed effects of cryosphere reduction include modification of river regimes due to enhanced glacial melt, snowmelt advance and enhanced winter base flow; formation of thermokarst terrain and disappearance of surface lakes in thawing permafrost; decrease in potential travel days of vehicles over frozen roads in the Arctic; enhanced potential for glacier hazards and slope instability due to mechanical weakening driven by ice and permafrost melting; regional ocean freshening; sea - level rise due to glacier and ice sheet shrinkage; biotic colonisation and faunal changes in deglaciated terrain; changes in freshwater and marine ecosystems affected by lake - ice and sea - ice reduction; changes in livelihoods; reduced tourism activities related to skiing, ice climbing and scenic activities in cryospheric areas affected by degradation; and increased ease of ship transportation in the Arctic.
