Unusual Volcanic Episode Rapidly Triggered Little Ice Age, Researchers Find

University of Colorado, Boulder Professor Gifford Miller collects dead plant samples from beneath a Baffin Island ice cap. Miller led a new study, to be published in in Geophysical Research Letters, which indicates the Little Ice Age began roughly A.D. 1275 and was triggered by repeated, explosive volcanism that cooled the atmosphere.

Washington, DC - New evidence from northern ice sheets suggests that volcanic eruptions triggered the multiple-century cool spell known as the Little Ice Age, and pinpoints the start of the climate shift to the final decades of the 13th century. Researchers have long known that the Little Ice Age began sometime after the Middle Ages and lasted into the late 19th century. But, estimates of its onset have ranged from the 13th to the 16th century.

According to the new study, the Little Ice Age began abruptly between 1275 and 1300 A.D., triggered by repeated, explosive volcanism and sustained by a self- perpetuating sea ice-ocean feedback in the North Atlantic Ocean, according to Gifford Miller, a geological sciences professor at the University of Colorado, Boulder (CU-Boulder), who led the study. The primary evidence comes from radiocarbon dates from dead vegetation emerging from rapidly melting icecaps on Baffin Island, combined with ice and sediment core data from the poles and Iceland, and from sea-ice climate model simulations, said Miller.

He and his colleagues will publish their findings on 31 January in Geophysical Research Letters, a publication of the American Geophysical Union (AGU).

During the cool spell, advancing glaciers in mountain valleys in northern Europe destroyed towns. Famous paintings from the period depict people ice-skating on the Thames River in London and canals in the Netherlands, places that were ice-free before and after the Little Ice Age. There is evidence also that the Little Ice Age affected places far from Europe, including South America and China.

While scientific estimates regarding the onset of the Little Ice Age extend from the 13th century to the 16th century, there has been little consensus, said Miller. "The dominant way scientists have defined the little Ice Age is by the expansion of big valley glaciers in the Alps and in Norway," said Miller. "But the time in which European glaciers advanced far enough to demolish villages would have been long after the onset of the cold period," said Miller, a Fellow at his university's Institute of Arctic and Alpine Research.

US - 62 below: Deep freeze grips much of Alaska

Even if it has been warmer than usual in much of the United States, there's no denying Alaska is seeing a real winter, even by its standards.

Anchorage is shivering through one of its coldest January's on record, while in Fairbanks, folks preparing for a sled dog race were being tested by temperatures nearly 50 degrees below zero. Farther inland, Fort Yukon has ranged from minus 50 to minus 62 degrees over the last three days, getting close to its record of minus 78.

Downtown Anchorage, Alaska, has seen a snowy and icy winter, including this scene from Jan. 18.
Anchorage's average temperature for January has been 2.7 degrees Fahrenheit, the Alaska Daily News reported. That's well below its average of 15 degrees, and only three other years (1947, 1925 and 1920) have been colder, National Weather Service data show.

It's so cold for Anchorage, the Daily News reported, that:
  • Cross country ski practices by the Junior Nordic League have been canceled due to temps dipping below the official cut-off of minus 4 degrees.
  • Tow trucks are so busy helping folks with dead car batteries that it can take up to four hours to get service.
  • Some schools have had only a handful of outdoor recess days this month.
In Fairbanks, where the Yukon Quest sled dog race starts on Saturday, some racers have had a hard time moving their trucks around due to a freeze that kept engines from starting, the Fairbanks Daily News-Miner reported.

Fort Yukon, for its part, dipped to 62 degrees below zero on Saturday, then hit 59 below on Sunday, the National Weather Service reported.

The deep freeze is in addition to the record snow and blizzard conditions seen earlier this month in towns like Cordova and Valdez. Even Anchorage is on track to see a record snow season, having received more than twice its average amount so far.

Bird enthusiasts are reporting rising numbers of snowy owls from the Arctic winging into the lower 48 states this winter in a mass southern migration that a leading owl researcher called "unbelievable."

Thousands of the snow-white birds, which stand 2 feet tall with 5-foot wingspans, have been spotted from coast to coast, feeding in farmlands in Idaho, roosting on rooftops in Montana, gliding over golf courses in Missouri and soaring over shorelines in Massachusetts.

A certain number of the iconic owls fly south from their Arctic breeding grounds each winter but rarely do so many venture so far away even amid large-scale, periodic southern migrations known as irruptions.

"What we're seeing now -- it's unbelievable," said Denver Holt, head of the Owl Research Institute in Montana.

Hyderabad/Bangalore: The unprecedented cold wave sweeping across southern India has claimed seven lives so far in Andhra Pradesh and broken century-old temperature records at several places in neighbouring Karnataka.

Chilly winds blew across coastal and north Telangana districts, claiming the lives of four elderly persons at Gudipudi village near Sattenapalle in Guntur district on Monday. Two women each died in Bapatla and Visakhapatnam.

In interior Karnataka, the harsh weather has broken records. Madikeri registered its lowest temperature in 132 years on Monday, with the minimum dropping to 4.8 degrees Celsius.

At 7.7 degrees Celsius, Mysore recorded its coldest day in 120 years and Bangalore saw its coldest day of January in 19 years with minimum temperature touching 12 degrees Celsius. In the plains, Belgaum was the coldest at 7.2 degrees.

The weather bureau says an extreme cold front has broken a series of low temperature records for Canberra, Goulburn and the Snowy Mountains.

The southern tablelands and Victoria's Alpine region have also been hit by the summer chill.

A rapidly moving cold front from Antarctica moved though Tasmania, Victoria, New South Wales and the ACT yesterday.

The icy and changeable weather delivered a low of -4 degrees Celsius and a dusting of snow to the Snowy Mountains.

Ice Age "News" is Wrong--It's Coming Sooner Than Later

When you consider the millions of words published as "news" about global warming, a massive hoax based on the theory that an increase in the Earth's levels of carbon dioxide (CO2), a minor atmospheric gas (0.0380%), it boggles the mind that reporters for a respected newswire, Reuters, would still be writing utter rubbish about it.

Just as the "news" about global warming was demolished in 2009 and again in 2011 with the leaked emails of the conspirators behind the fictions of the United Nations Intergovernmental Panel on Climate Change (IPCC), the main agency behind the hoax, on January 9, Nina Chesney of Reuters London Bureau, reported about a paper in the journal, Nature Geoscience, that the "Next Ice Age not likely before 1,500 years: study."

The paper claimed that "Concentrations of the main gases blamed for global warming reached record levels in 2010 and will linger in the atmosphere for decades even if the world stopped pumping out emissions today, according to the U.N.'s weather agency."

The U.N. does not have a "weather agency." It has a propaganda agency devoted in its own words to "climate." The two are not the same. Weather is what is occurring right now and climate is the measurement of trends over centuries.

The entire north India shivered on Monday as 11 more people succumbed to the cold sweeping the region pushing the death toll to 39.
New Delhi: The entire north India shivered on Monday as 11 more people succumbed to the cold sweeping the region pushing the death toll to 39. Dense fog and dipping temperatures threw normal life out of gear at several places as nine deaths occurred in Punjab and two in Uttar Pradesh since last evening.

The death count from the harsh weather has risen to 30 in Uttar Pradesh where Fatehgarh with a minimum temperature of 3.9 degrees was the coldest place in the state. The national capital woke up to a thick blanket of fog which reduced the visibility to almost zero in some areas and disrupted rail and air traffic.

Dense fog also hit rail services in the region with over 40 trains running behind schedule, a railway spokesperson said.

Cold conditions prevailed in Kashmir with the minimum temperatures dropping several degrees below freezing point as the weather department forecast light to moderate snowfall at many places. Sub-zero night temperatures have resulted in freezing of water supply lines in many areas. Mercury in the skiing resort of Gulmarg in north Kashmir plummeted to a minimum of minus 6.8 degrees Celsius.

Dr. Marty Haulena tends to a sick green sea turtle at the Vancouver Aquairium.
For the third time in two weeks a green sea turtle - a prehistoric species that's 150 million years old and that's now threatened - has washed up on B.C.'s shores, a rare appearance that's baffling ocean experts.

The sub-adult male was spotted by a visitor on Combers Beach in Pacific Rim National Park on Wednesday, the Vancouver Aquarium said Friday.

The giant turtle - females can weigh up to 200 kgs -- was in poor shape and wasn't expected to survive, said Dr. Dennis Thoney on Friday at the aquarium, where the turtle was transported for an examination.

"It's just too far gone," he said. "If they're on the shore, that's usually an indication there's something wrong with them."

US: Supreme Court Will Hear Secret Service Agents' Immunity Claims Over Arrest at Cheney Event

Washington - The Supreme Court said Monday it will hear an appeal from Secret Service agents who say they should be shielded from a lawsuit over their arrest of a Colorado man who confronted Vice President Dick Cheney.

The justices will review a federal appeals court decision to allow Steven Howards of Golden, Colo., to pursue his claim that the arrest violated his free speech rights. Howards was detained by Cheney's security detail in 2006 after he told Cheney of his opposition to the war in Iraq.

Howards also touched Cheney on the shoulder, then denied doing so under questioning. Appellate judges in Denver said the inconsistency gave the agents reason to arrest Howards.

Even so, the appeals court said Howards could sue the agents for violating his rights - an unusual twist that the agents and the Obama administration said conflicts with other appeals court decisions and previous high court rulings in similar cases.

Justice Elena Kagan is not taking part in the case, probably because she worked on it while serving in the Justice Department.

So much for Global Warming scare: Arctic ice shrank during Little Ice Age and now in longest decline seen over past 1,450 years

Research published in a top scientific journal says Arctic sea ice has declined more in the last half-century than it has any time over the last 1,450 years.

The study, which gives the most detailed picture ever of the northern oceans over the previous millennium-and-a-half, also concludes the current decline has already lasted longer than any previous one in that period.

"When we look at our reconstruction, we can see that the decline that has occurred in the last 50 years or so seems to be unprecedented for the last 1,450 years," Christian Zdanowicz of the Geological Survey of Canada said Wednesday.

"It's difficult not to come up with the conclusion that greenhouse gases must have something to do with this," added Mr. Zdanowicz, one of the co-authors of the report in Nature.
