Will the “Epic Iceberg” smashup change currents

Satellite picture of pending giant iceberg collision in Antarctica

Giant Iceberg Headed for Trouble

Pictured in a January 7 satellite image—about a month before a massive collision—the Luxembourg-size iceberg B9B floats toward the hundred-mile-long (160-kilometer-long) floating “tongue” of Antarctica’s Mertz Glacier. The tongue is already weakened by growing rifts on both sides of its midsection.

The 60-mile-long (97-kilometer-long) B9B iceberg smashed into the Mertz Glacier Tongue on February 12 or 13—creating a second, 48-mile-long (78-kilometer-long) iceberg, according to a the Antarctic Climate and Ecosystems Cooperative Research Centre (ACECRC).

The two icebergs are now floating at sea, side by side, and debris from the breakup is filling the once clear waterway beside Mertz Glacier (map). Prior to the separation, iceberg B9B had spent nearly 20 years floating close to the glacier.

A tiny bat living in central Italy has emerged from the dark and started hunting by day.

Soprano pipistrelle (Pipistrellus pygmaeus)

This switch in hunting strategy is highly unusual among insectivorous bats, which routinely hunt at twilight or by night to avoid predators.

Yet a small group of soprano pipistrelles has been spotted brazenly flying by day in a mountain canyon within an Italian beech forest.

Only one other species of insectivorous bat frequently flies during daylight.

A research team lead by Dr Danilo Russo, a bat expert from the University of Bristol, UK and the University of Naples Federico II in Italy report the discovery in the journal Mammalian Biology.

Russia has big Bomb of Mass Destruction!

One hundred to one thousand times the normal atmospheric levels of the greenhouse gas methane (CH4), a greenhouse gas 25 times as powerful as CO2 at warming the earth, were found this summer over the Siberian shelf in the Arctic Ocean. The Siberian shelf contains enormous amounts of methane – 13 times the total carbon content of the earth’s atmosphere.

Much more here on this topic.

A vast shallow sea lies north of Siberia. One quarter of the world’s continental shelves are found in the Arctic. Seven great rivers pour carbon rich sediment onto the Arctic shelves. During the ice ages the very shallow and very vast east Siberian sea was above sea level causing deep permafrost to sequester the carbon at negative 17 Celsius. Enormous amounts of methane were trapped as methane hydrate ice.Rapid warming of the Arctic is now destabilizing the methane ice in parts of the east Siberian sea.

The Real Climate Gate–Bombshell Document Leak

Daily Kos: The Real Climate Gate–Bombshell Document Leak
About an hour ago a document leaked out of the UN Secretariat that blows the top off the climate talks here in Copenhagen. For reasons I don’t know it has my name scrawled across the top–I didn’t leak it, but it confirms what I’ve been saying for months. The proposals that the UN is considering come nowhere near meeting their own already inadequatetarget of 2 degrees. Instead, they will lead to at least 50% more heat.

Wunder Blog : Weather Underground

FULL STORY HERE: Wunder Blog : Weather Underground
The dramatic loss of Arctic sea ice in recent years has created a fundamental new change in the atmospheric circulation in the Northern Hemisphere that has sped up sea ice loss and is affecting fall and winter weather across most of the Northern Hemisphere, according to several recent studies. Arctic sea ice loss peaks in September and October, exposing a large area of open water that heats the air above it. This extra heat has helped drive September – November air temperatures in the Arctic to 1°C 1.8°F or more above average over about half of the depth of the lower atmosphere Figure 1. This deep layer of warm air has grown less dense and expanded, pushing the top of the troposphere the lower atmosphere higher. The result has been a decrease in the pressure gradient the difference in pressure between the North Pole and mid-latitudes. With not as much difference in pressure to try and equalize, the jet stream has slowed down in the Arctic, creating a major change in the atmospheric circulation for the Northern Hemisphere.

An alphabetical journey of the impacts of climate change around the globe.

As the nations of the world gather in Copenhagen, the Wonk Room has prepared this alphabetical journey of the impacts of climate change around the globe.

A

East Antarctica, long stable, is now losing ice.

B

Bolivia needs $1 billion over the next seven years to build reservoirs, as the glaciers that hold the nation’s water supply are shrinking rapidly.

C

Leatherback sea turtles that spawn on the beaches of Costa Rica are threatened with extinction by warmer temperatures and rising seas.

D

Denmark joined United States, Norway, Canada, and Russia in identifying climate change as “the most important long-term threat” to future existence of polar bears.

E

The rapidly warming highlands of Ethiopia are becoming too hot for its elite athletes, such as local-born Haile Gebrselassie, to train there.

F

Noting the unprecedented floods this year in Fiji, Prime Minister Commodore Voreqe Bainimarama recently warned that rising sea levels affect not just the islands’ economies, but put into doubt the very existence of his nation.

G

Greece suffered through another storm of extreme wildfires this summer as heat waves and drier conditions increase.

H

Global warming-fueled hurricanes, intense poverty, and widespread deforestation combine to form a gathering storm of disasters for Haiti.

I

The deforested peatlands of Indonesia are drying, disintegrating, and burning.

J

The increasingly early arrival of cherry blossoms in Japan reflects rising global temperatures.

K

The more frequent and severe droughts that are killing off the elephants will likely trigger more conflicts in the arid lands of northeast Kenya.

L

The incidence of wildfires in the cedar forests of Lebanon has increased tremendously over recent years.

M

“If things go business-as-usual, we will not live, we will die,” Maldives President Mohammad Nasheed told the UN General Assembly. “Our country will not exist.”

N

The ministers of Nepal have held the world’s highest cabinet meeting on Mount Everest, as rapidly rising temperatures have reduced snowfall over the mountains and caused glaciers to melt.

O

More than 50 per cent of the population of Oman lives on coastlines vulnerable to rising seas, but its supplies of peridotite may help sequester carbon dioxide emissions.

P

The massive floods that killed hundreds in the Philippines this summer are becoming the norm.

Q

Petroleum-soaked Qatar emits 60 tons of carbon dioxide per person, the most of any nation on earth.

R

Increased floods and malaria outbreaks from global warming, deforestation, and unsanitary conditions have hit Rwanda hard in the past decade.

S

The inhabitants of the Alpine villages of Fieschertal and Fiesch in Switzerland have asked for the Pope to bless their prayers for the restoration of their nation’s glaciers, which shrank by 12 percent over the past decade.

T

Newly discovered, exotic species like the fanged frog of Thailand are especially vulnerable as climate change will further shrink their already restricted habitats.

U

Agriculture in the United States has been ravaged this year by catastrophic droughts in Texas and California, heat waves in Louisiana and Nebraska, storms across the High Plains and the Midwest, floods in North Dakota and Minnesota, and torrential rains in Illinois and Georgia.

V

Speaking from Vatican City on the eve of the Copenhagen conference, Pope Benedict XVI counseled “all people of good will to respect the laws laid down by God in nature and to rediscover the moral dimension of human life.”

W

Warming oceans and sea level rise threaten the coral reefs of the remote Polynesian islands of Wallis and Futuna.

X

The nomadic descendents of Kublai Khan in Inner Mongolia, where Xanadu once stood, are being driven from the grasslands as the Chinese government attempts to fight the region’s desertification.

Y

Sanaa, the capital of Yemen, may be the first capital city in the world to run out of water, as drought and overuse diminish its supply.

Z

On the border of Zambia and Zimbabwe, the flow of Victoria Falls is far below average, as drought and high temperatures reduce the Zambezi.

A greener way to get electricity from natural gas

A greener way to get electricity from natural gas

ScienceDaily: Your source for the latest research news and science breakthroughs — updated dailyScience NewsShare Blog CitePrint Email BookmarkA Greener Way to Get Electricity from Natural GasScienceDaily Dec. 3, 2009 — A new type of natural-gas electric power plant proposed by MIT researchers could provide electricity with zero carbon dioxide emissions to the atmosphere, at costs comparable to or less than conventional natural-gas plants, and even to coal-burning plants. But that can only come about if and when a price is set on the emission of carbon dioxide and other greenhouse gases — a step the U.S. Congress and other governments are considering as a way to halt climate change.

The SwiftHack ClimateGate Scandal: What You Need to Know

Daily Kos: The SwiftHack ClimateGate Scandal: What You Need to Know
First of all, this story should never have been called ClimateGate. Given the similarities between this smear job and the Swift Boat attacks on Senator John Kerry, SwiftHack is a far more appropriate name.I've attempted to cover the major points of interest in this story. Consider this post a perpetual work in progress. It will be continually updated. Please leave appropriate links and angles I'm missing in the comments.For your convenience, the following 6 points each links to the corresponding section of this post:

1.) The scientific consensus on climate change remains strong.The impacts of catastrophic climate change continue to rear their ugly head.Hacking into private computer files is illegal.All of the emails were taken out of context.The story is being pushed by far-right conspiracy theorists.Scientists are human beings and they talk frankly amongst themselves.
