Arctic Ice Decline Much Worse Than Expected

As the extent of Arctic sea ice declines to levels unrecorded since satellite monitoring began, the National Snow and Ice Data Center has released a new analysis that shows the situation to be worse by far than even the most pessimistic models predicted.

It's a perverse endorsement of one of the most popular denier memes - that you can't rely on climate models because the world is too complicated to be reduced to a compilation of computer data. But, thanks to the expertise (and conservative nature) of the scientists behind this work, the models have shown the direction with perfect accuracy: it's the terrifying extent that they have failed to anticipate.

In addition to the catastrophic conditions currently prevailing in the Arctic, the NSIDC has also drawn attention to the dramatic melting occurring this year in Greenland. And all this is supported and reinforced by the Polar Science Center's ongoing calculation of Arctic ice volume.

The trends are all down. Or as James Hansen put it in the Washington Post last week, "Climate change is here - and it's worse than we thought."

Warming Climate Brings Sea Level Rise, Land Loss and Marine Migrations to Europe’s Seas


Sea level rise in EuropeEurope’s seas are changing at an unprecedented rate, much faster than climate scientists anticipated.
Seawater temperatures have been rising around 10-times faster than average over the past 25 years, while wind speeds have also been increasing. The combination of rising sea levels and stronger winds has resulted in the loss of 15% of Europe’s coasts.

European sea surface temperature increases were three to six-times higher than the global average from 1986-2006, a research team found, as Arctic sea ice has melted, according to the Climate Change and European Marine Ecosystem Project Report (CLAMER).

“Change has been clearly visible and is much more rapid than we thought was possible,” Carlo Heip, chair of the CLAMER project and lead author of the report, told Reuters last Tuesday.

Melting ice sheets and glaciers add more uncertainty regarding how fast sea levels will rise, which threatens populations in all low-lying areas of Europe. Current estimates for 2100 suggest European sea levels could rise 60 centimeters and up to 1.9 meters along some parts of the U.K. coast.

“Scenario simulations suggest that by the end of the 21st century, the temperature of the Baltic Sea may have increased by 2 to 4 degrees centigrade, the North Sea by 1.7 degrees, and the Bay of Biscay by 1.5 to 5 degrees,” the researchers found.

These aren’t the only large-scale change taking place, offshore or on-shore, as a result of relatively abrupt changes in climate, they noted.

Ocean warming and the melting of sea ice across the Arctic Ocean off Russia’s northern coast is bringing about changes in the marine food chain as marine life migrates to the Atlantic from the Pacific. Some species may wind up being able to thrive in their new environments, but the migrations are bound to have significant impacts on fish populations, as well as commercial fisheries and the human populations that depend on them, according to the report.

The CLAMER research team also found that some strains of bacteria were becoming more prevalent, potentially becoming threats to human health. Strains of cholera have increased in the North Sea over the past 50 years, they noted, perhaps due to changing seawater temperatures.

The research team urged European Union officials “to keep its finger on the pulse” of marine climate change, urging, among, among other recommendations, greater study of sea level changes due to the break-up of ice sheets and melting, coastal erosion, temperature changes, ocean acidification, marine ecosystems and ocean circulation changes.

Requiem for the Bears?

With polar bears getting less time on the shrinking ice to fatten up on seals, they are coming ashore with less energy stored up for the difficult summer months.

Frigid Winters and the Polar Vortex

Scientists are pursuing ideas about how a drastic decline of sea ice in the Arctic might be playing a role in a pattern of frigid temperatures, snow and ice at points south.

Loss of Arctic Ice May Promote Hybrid Marine Mammals

http://www.sciencedaily.com/releases/2010/12/101216132949.htm ScienceDaily (Dec. 16, 2010) — Scientists have expected for some time that the Arctic Ocean will be ice-free in summer by the end of this century. Writing in the December 15 issue of the journal Nature, a trio of researchers say the seasonal loss of this ice sheet, a continent-sized natural barrier between species [...]

A Russian Warning on Retreating Ice

Sea ice in the Arctic is again in rapid retreat this summer, putting the region on pace to match the record lows seen in 2007, the head of Russia's environmental agency has been quoted as saying.

Sea Ice in the Arctic Not Recovering: Another Critical Minimum Forecast

http://www.sciencedaily.com/releases/2010/06/100624112306.htm ScienceDaily (June 24, 2010) — A critical minimum for Arctic sea ice can again be expected for late summer 2010, according to researchers.  Scientists from the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association (AWI) in Bremerhaven and from KlimaCampus of the University of Hamburg have now published data in this context [...]

Book Review: A World Without Ice by Dr. Henry Pollack


A World Without IceIce asks no questions, presents no arguments, reads no newspapers, listens to no debates. It is not burdened by ideology and carries no political baggage as it changes from solid to liquid. It just melts."

—-

Even in its absence, ice rules land and sea. The unmistakable signs of its power and influence are seen in the planet's landscape, and in the cycle of water, wind, ocean currents, and climate. Penetrating south overland towards the middle of North America during the last ice age, the ice retreated northward again in its slow-turning geologic oscillation leading to the interglacial period in which we now live.

It is within this period of relative warmth and stability in Earth's climate that all human experience exists.  Just as humans began organizing an agrarian society about ten thousand years ago, global temperatures plateaued and began naturally tapering towards the next ice age. That is, until the unmistakable signs of human activity upset Earth's natural climactic cycle. One of the first, omened signs of that influence lay in the rapid acceleration of  changes in the world's ice.

If you live on Earth, your fate is tied to the ice, and the ice is melting.

Dr. Henry Pollack's new book A World Without Ice tells the story of ice and human civilization's relationship to it. A professor of geophysics at the University of Michigan, Dr. Pollack combines a formidable and wide-ranging scientific understanding of Earth and climate with an engaging literary style. Despite the complex and grave nature of the issue at hand, Dr. Pollack gives a captivating explanation of how ice drives the delicate balance of Earth's climate, and how that balance has been knocked off kilter by human activity.

Step-by-step, Dr. Pollack lays before the reader the unmistakable signs, effectively refuting the endless litany of the "climate contras" and their "trenches of denial." But A World Without Ice is no polemic. It is a clear-headed account of the situation in which we now find ourselves – unwittingly at first, but no longer. The signs are manifest and growing. Action cannot be left to future generations; doing so is to forgo the moral imperative of those who would see the signs and choose to ignore them.

So Dr. Pollack calls, in the end, for a Churchillian optimism, that of "finding opportunity in every difficulty" as we chart a course toward a sustainable future. The challenges we face are immense, and thus so is the opportunity – but only if we choose clear-headed action over small-minded denial and self-interest. The choice is ours now to make.

A World Without Ice is an important book for anyone truly interested in making the right choice.
