Large areas of the Earth's surface are experiencing rising maximum temperatures, which affect virtually every ecosystem on the planet, including ice sheets and tropical forests that play major roles in regulating the biosphere, scientists have reported.
For that topic the scientists deferred to Don Blankenship, a University of Texas geophysicist and glaciologist with decades of experience using powerful radar to analyze ice sheets and glaciers in Antarctica.
These findings suggest that Greenland's glaciers have been experiencing increasing ice loss for at least three decades — a result that may reinforce scientists» concerns over the stability of the melting ice sheet.
Some scientists believe the ice sheet experienced significant melting during the relatively warmer conditions of the Pliocene, while others think it has remained almost entirely frozen for the last 14 million years.
What truly stumps scientists, he says, is the fact that Antarctica experiences huge ice losses and competing gains in different regions, a pattern that is unaffected by this study.
The Russian and American scientists have never before experienced anything of such magnitude, and in addition to powerful emissions from shallow waters where over 100 readings were recorded, it is spewing up from within cracks in the Arctic ice in the open seas far from land.
Emerging from a winter that has had staggeringly warm Arctic temperatures, scientists monitoring the vast Greenland ice sheet announced Tuesday that it is experiencing a record - breaking level of melt for so early in the season.

While it's no secret that much of the Antarctic Peninsula is rapidly melting, scientists were disappointed when they recently found that a previously stable region of Antarctica is experiencing rapid ice loss - so much so that it is even affecting Earth's gravity field.
Nearly the entire ice cover of Greenland, from its thin, low - lying coastal edges to its 2 - mile - thick (3.2 - kilometer) center, experienced some degree of melting at its surface, according to measurements from three independent satellites analyzed by NASA and university scientists.

As this week started, scientists monitoring the Greenland ice sheet experienced a shock - over 10 per cent of the island's ice sheet surface was experiencing melting of over 1 millimetre.
Scientists and politicians are keen to hold global warming to 1.5 C above pre-industrial levels because they fear that a world that warms to such a level will experience severe loss of ice, particularly from Greenland's massive shield of glaciers, and that the melting will in turn trigger considerable rises in sea levels.
(03/26/2013) Climate scientists have linked the massive snowstorms and bitter spring weather now being experienced across Britain and large parts of Europe and North America to the dramatic loss of Arctic sea ice.
Hang on... we've been told for years by apparent top climate scientists to expect less snowfalls, climate models predict warmer winters, ex-politicians claiming ice - free polar caps, hand - wringing news articles of children who would never experience snowfalls, on and on... but now we're expected to believe exactly the opposite because that's what's happening now.
Well; if a statement regarding atmospheric cooling is taking place, and we know from past experience (climate history) that if this cooling continues and the build up of ice continues in Antartica like it is; then it is possible that the planet may very well be headed back into an ice age - and when this «atmospheric cooling» trend is mentioned on the GISS [NASA] Webpage, and by one of the GISS scientists (Kate Marvel, a climatologist at GISS and the paper's lead author) then i would have to conclude that the are embracing the science revealing evidence that such mechanics are, taking place, and I view their statemnt as an endorsement and ot their recognition, of global cooling.
As one of the world's leading polar scientists with more than 47 years» experience of visiting and measuring ice at the poles, he provided a lucid and sobering explanation of the impact of global warming on the poles, and the way in which the disappearance of polar ice is itself hastening global warming, and contributing to extreme weather events such as the March blizzards preventing some people attending the conference.
