Posted on 03/01/2009 6:49:24 AM PST by DBCJR
One of the world's most important remaining ice reserves on Earth remains deceptively cold.
As the planet's poles thaw out, global sea level rise looms as one of the most dangerous side effects of global warming. Any excess chill may seem like good news for the planet. But a new study suggests that Greenland is lagging behind rest of the northern hemisphere's warming trend and that it's bound to catch up soon.
Air temperatures have been rising steadily in the northern half of the planet since about 1975, when scientists think the effects of human-induced global warming began to dominate the climate. But Greenland was left behind, perhaps kept cool when dust released from the eruptions of Mount St. Helens, El Chicon and Mt. Pinatubo reduced the amount of sunlight hitting the ice.
Around 1985 the icy island started to thaw, and has continued apace ever since. Climate scientists have been alarmed by the speed of the melting, watching as glaciers recede and meltwater pools in lakes on top of the ice.
Still, in an analysis of temperature records in Greenland from 1840 until 2007, Jason Box of Ohio State University and a team of researchers found that the ice sheet remains between 1.0 and 1.5 degrees Centigrade (1.8 to 2.7 degree Fahrenheit) behind the rest of the northern hemisphere. And it should catch up in the coming decades.
"The temperature increase could be three to four times what we've seen already. If that holds it will be far above anything we've seen before," David Bromwich of Ohio State University said. "The ice will continue melting and probably accelerate in the future."
This is a STATEMENT OF FAITH AND NOT EMPIRICAL FACT DAMMIT! I HATE THESE RELIGIOUS AGW FREAKS!
How can something that ended a decade ago catch up???
It is quantum thinking, a new thing, where you are thinking along logically and then suddenly leap to an otherwise illogical conclusion.
Catch words...”Probably” “think” “if”...
Who are you yelling at? Me or the article?
“Allegedly”, “seems”, and “appears” are good words, too. That is a way you can say most anything and get out of it.
What the hell does “deceptively cold” mean? Greenland is just faking it? It’s playing a con, like the envirowhackos? These people are beyond shameless.
“Deceptively cold” means it’s cold, but at the same time it’s actually warm.
Makes perfect sense to me.
Recent massive volcanoes have risen from the ocean floor deep under the Arctic ice cap, spewing plumes of fragmented magma into the sea, scientists who filmed the aftermath reported Wednesday.
The eruptions -- as big as the one that buried Pompei -- took place in 1999 along the Gakkel Ridge, an underwater mountain chain snaking 1,800 kilometres (1,100 miles) from the northern tip of Greenland to Siberia.
Scientists suspected even at the time that a simultaneous series of earthquakes were linked to these volcanic spasms.
But when a team led of scientists led by Robert Sohn of the Woods Hole Oceanographic Institution in Massachusetts finally got a first-ever glimpse of the ocean floor 4,000 meters (13,000 feet) beneath the Arctic pack ice, they were astonished.
What they saw was unmistakable evidence of explosive eruptions rather than the gradual secretion of lava bubbling up from Earth's mantle onto the ocean floor.
From Ohio State University News, Dec 2007...
"EARTH'S HEAT ADDS TO CLIMATE CHANGE TO MELT GREENLAND ICE"
COLUMBUS , Ohio -- Scientists have discovered what they think may be another reason why Greenland 's ice is melting: a thin spot in Earth's crust is enabling underground magma to heat the ice.
They have found at least one hotspot in the northeast corner of Greenland -- just below a site where an ice stream was recently discovered.
The researchers don't yet know how warm the hotspot is. But if it is warm enough to melt the ice above it even a little, it could be lubricating the base of the ice sheet and enabling the ice to slide more rapidly out to sea.
A political assumption presented as scientific fact, with no evidence provided to support it. As a matter of fact, it isn't true. Antarctica has gotten colder while the Arctic ice cap has grown significantly over the past year, after having been vastly underestimated in size by a faulty ice sensor. An ice area the size of California was simply "misplaced" by the data collectors. At the same time, overall sea ice extent in 2009 is running ahead of that measured in recent years.
The bias of the news media knows no bounds, whether the subject is politics, the economy or global warming. All of these are in fact related.
What the hell does deceptively cold mean? Greenland is just faking it? Its playing a con, like the envirowhackos? These people are beyond shameless.
Deceptively cold means that the temperatures may be registering cold but we know that it is NOT cold because of Global Warming, therefore, it is deceptively cold. The Prophet Gore has spoken truth, as inconvenient as it may be. And, while the temperatures may inconveniently not be playing along, we know that they are, in fact, deceptive because the Prophet has spoken. Greenland is obviously the target of a vast right-wing conspiracy to deceive the “enlightened”.
Great post! Thank you
VENEZUELA: Chavez calls for global offensive for socialism
August 31, 2005
"The environment is suffering damage that could be irreversible global warming, the greenhouse effect, the melting of the polar ice caps, the rising sea level, hurricanes with terrible social occurrences that will shake life on this planet."
"I believe this idea has a strong connection with reality. I don't think we have much time. Fidel Castro said in one of his speeches I read not so long ago, 'tomorrow could be too late, let's do now what we need to do'."
"I believe it is time that we take up with courage and clarity a political, social, collective and ideological offensive across the world a real offensive that permits us to move progressively, over the next years, the next decades, leaving behind the perverse, destructive, destroyer, capitalist model and go forward in constructing the socialist model to avoid barbarism and beyond that the annihilation of life on this planet."
--Hugo Chavez, at the 16th World Festival of Youth and Students, held in Caracas on August 8-15, 2005
Obama climate czar has socialist ties
Group sees 'global governance' as solution
Stephen Dinan, January 12, 2009
Until last week, Carol M. Browner, President-elect Barack Obama's pick as global warming czar, was listed as one of 14 leaders of a socialist group's Commission for a Sustainable World Society, which calls for "global governance" and says rich countries must shrink their economies to address climate change.
By Thursday, Mrs. Browner's name and biography had been removed from Socialist International's Web page, though a photo of her speaking June 30 to the group's congress in Greece was still available.
Then I yell with you!
Chavez is a dufus. He is one of the largest oil producers in the Western Hemisphere. Buying into global warming hurts demand for his cash cow.
Well, OK - Obama hasn't done anything like that yet, but I'm sure that he's going to, so it's "news".

Here are two views of the meltwater lakes they're talking about, from July 2002 and July 2008, on the 16th of the month. One of these drained suddenly in 2006, when some scientists happened to be on hand studying it, so it made big news. The pattern of lakes in 2002 and 2008 is very much the same, and it looks like the edge of the ice follows the same line very closely, so I don't know about "continuing apace". I can see getting worried about these lakes, though. They are obviously a potentially active agent of erosion. Are there more of them in the 2008 image?
Thank you for your post and the satellite map comparison. The type comparison that you ask is one that likely needs computer analysis to identify. The outward range of change one would expect would seem undetectable to the human eye.
