Mastodons weren't hunted to extinction by Ice Age humans - they simply froze to death, new study finds

Despite popular belief that North American mastodons were hunted to extinction by Ice Age humans, a new Canadian-led study is claiming that the prehistoric beasts simply froze to death.

"To think of scattered populations of Ice Age people with primitive technology driving huge animals to extinction, to me is almost silly," said Grant Zazula, chief paleontologist for the Yukon Territory and the study's lead author.

"It's not human nature just to see everything in your path and want to kill it," he said.

The paper, published this week in the Proceedings of the National Academy of Sciences, carbon dated 36 mastodon bones from across Canada and the United States.

Major snowstorm to plaster Northeast U.S.

A major storm will impact the Northeast through Thursday, complete with gusty winds, substantial snow, heavy rain, a wintry mix and flooding.

A strengthening storm along the mid-Atlantic coast will push northward on Tuesday, then inland Tuesday night through Thursday.

According to AccuWeather Chief Meteorologist Elliot Abrams, "This will be a snowstorm for some areas well inland, while impacts similar to a tropical storm will occur along the coast, including much of Interstate-95."

Heavy Interior Snow

The heaviest snow, a general 6 to 12 inches is forecast to fall on the Endless, Catskill and Adirondack mountains. Locally higher amounts can occur.

While the snow will be welcome by those with skiing interests, travel will become extremely treacherous and AccuWeather.com Meteorologist Ben Noll stated that the "wet-clinging nature of the snow could lead to downed trees and power outages."

Experts say that record heat causes record ice

It is one of the greatest puzzles in the science of climate change, and has been used by skeptics to cast doubt on global warming: Why, when the world is getting hotter, is the Antarctic getting colder?

Now, a scientist thinks she may have uncovered the answer.

Cecilia Bitz, an atmospheric scientist from the University of Washington in Seattle, believes that oceanic currents are taking heat away from Antarctica and carrying it north, reports the Sunday Times.

Northern Hemisphere snow cover this fall the most extensive ever recorded

Data from Rutgers University Global Snow Lab show that Northern Hemisphere snow cover extent exceeded 22 million square kilometers this fall (September, October, and November) exceeding the previous greatest fall extent recorded in 1976.

During November alone, North America had its most extensive snow cover on record, the Lower 48 had its most extensive snow cover on record, and Canada had its second most extensive snow cover on record,

Not unexpectedly, The Washington Post goes to great lengths to explain why snow cover can increase in a warming world.

New study finds California drought worst in 1,200 years

The last three years of drought were the most severe that California has experienced in at least 1,200 years, according to a new scientific study published Thursday.

The study provides the state with breathtaking new historical context for its low reservoirs and sinking water tables, even as California celebrated its first good soaking of the season.

Analyzing tree rings that date back to 800 A.D. -- a time when Vikings were marauding Europe and the Chinese were inventing gunpowder -- there is no three-year period when California's rainfall has been as low and its temperatures as hot as they have been from 2012 to 2014, the researchers found.

"We were really surprised. We didn't expect this," said one of the study's authors, Daniel Griffin, an assistant professor in the University of Minnesota's department of geography, environment and society.

The report, published in the journal of the American Geophysical Union, was written by researchers at Massachusetts' Woods Hole Oceanographic Institution and the University of Minnesota.

The scientists measured tree rings from 278 blue oaks in central and southern California. Tree rings show the age of trees, and their width shows how wet each year was because trees grow more during wet years.

The researchers compared the information to a database of other tree ring records from longer-living trees like giant sequoias and bristlecone pines, dating back 1,200 years.

Meanwhile, the rain that California received this week provided a promising start to a winter that water managers say needs to be relentless and drenching to break the drought cycle.

Waist-deep snow in China with the most severe snowstorm seen in years

The snow is up to 3 feet (90 cm) deep, leaving residents struggling to open doors.

A blizzard lasting more than 60 hours hit Fuyuan County, a border town in northeast China's Heilongjiang Province on Thursday.

Local communities banded together to clear snow from roads, and the county government said a contingency plan is in place to relieve economic stresses due to the snow.

First winter snowfall breaks Juneau, Alaska records

The National Weather Service says Saturday night's winter storm brought record-setting snowfall to Juneau.

Eight-and-half inches of snow fell at Juneau International Airport over the 24-hour period that ended at midnight on Sunday. That broke a record of 6.3 inches of snow set back in 1946.

Just over 9 inches (9.1) fell at the National Weather Service office on Back Loop Road. That broke the record of 5.4 inches set in 2010.

An 11-year-old record of 5.8 inches of snow at Lena Point was broken with Sunday's snowfall of 9.6 inches.

At Outer Point on Douglas Island 5 inches fell, while 4.5 inches fell in Pelican on Sunday. That was nearly double the old record of 2.5 inches that fell in Pelican on Nov. 30, 2006.

Ice storm with deep snow in Serbia: People experiencing mental breakdown after 48 hours without electricity, water and heating

3 Dec 14 - "48 hours of agony in Majdanpek, people mentally break!" says headline.

Put on your coat and hat and get under a blanket and wait to pass this evil, say angry residents of Majdanpeka. At night it is very cold.

The city is bound by snow and ice, without electricity, water and heating, and the torture is far from over. The fourth attempt to connect pokidna transmission network, this afternoon failed. It's agony.

Business is great, joked a shop owner: he has sold burners for gas. These gadgets over the past two days in Majdanpeku have become worth gold, because it is only on them that food can be prepared.

Mad blizzard swallows cars, streets, buildings in Far East Russia

Winter has come with a vengeance: Russia's snow-and-ice-bound Far East regions have declared states of emergency. Traffic chaos is rife, with cars stuck or sliding uncontrollably. Residents are trying to push cars, and also stop them with their bodies.

The cold and snowy season began in Russia's Far East - including the cities of Vladivostok and Khabarovsk - on Dec. 1, the first day of winter proper according to the calendar. Yet municipal services were not ready to deal with weather conditions, people on social networks complained.

Snowfall in Khabarovsk - reportedly the heaviest in decades - forced the city authorities to announce the state of emergency and call in military to aid with the storm's aftermath.

Harsh weather conditions caused traffic to come to a standstill, with people being unable to use either public transport or their own cars.


Challenged to not only find and then dig their cars out from under the snow, drivers also had to push their vehicles when they were stuck on snow and ice-covered roads, as well as stopping them from moving uncontrollably.

U.S. Lake Erie temperature at end of November coldest since 1976

Lake Erie's water temperature at the end of November fell to 40 degrees. That's the coldest Nov. 30 reading in Buffalo since 1976, when the lake temperature was 38 degrees. Anyone old enough to remember November 1976 needs no further reminder of what happened the following January.

The lake froze, and sustained winds during the Blizzard of '77 blew 3 feet of accumulated snow off the ice and dumped it across the Niagara Frontier. Great Lakes scientists say it's too early to tell if the lake's present condition will lead to that kind of snow catastrophe this winter.

Until the lake freezes, there's always a chance for lake-effect snow. But as the water turns colder, there's less chance for a repeat of the heavy lake-effect snowfall that hit the area a couple of weeks ago. "It really depends on what happens now and over the next few weeks or month," said Eric J. Anderson, a forecaster at the Great Lakes Environmental Research Laboratory in Ann Arbor, Mich.
