Earth Changes
The 20-year-old skier died in hospital after she was buried by a rare avalanche at a resort in Utah.
The same storm front that created the avalanche conditions also brought blizzards to major cities, closing roads and halting transport systems.

The finding will give much needed perspective to satellite instruments that measure ice loss on the continent, and help improve estimates of future sea level rise.
"Our preliminary results show that we can dramatically improve our estimates of whether Antarctica is gaining or losing ice," said Terry Wilson,* associate professor of earth sciences at Ohio State University.
These results come from a trio of global positioning system (GPS) sensor networks on the continent.
Wilson leads POLENET, a growing network of GPS trackers and seismic sensors implanted in the bedrock beneath the West Antarctic Ice Sheet (WAIS). POLENET is reoccupying sites previously measured by the West Antarctic GPS Network (WAGN) and the Transantarctic Mountains Deformation (TAMDEF) network.
In a contest between a toad and a crocodile, it seems obvious the croc will win. Not, though, if its adversary is a cane toad - the poisonous pests laying waste to Australian wildlife.
Researchers have found that, in some waterways in the Northern Territory, numbers of freshwater crocodiles have more than halved over the past two years. The reason is cane toads, which are fatal when eaten.
"Your fellow Jaffrey residents have stepped up and made this a more bearable situation," Walt Pryor, recreation department director for the town of 5,700, told the congregation Sunday morning.
White Sulphur Springs reported 29 degrees below zero to the National Weather Service today, stretching way beyond the last daily record low of 17 degrees below zero set in 1922.
"We're waiting for a lot of reports to come in still," said Scott Coulston, a meteorologist with the National Weather Service in Great Falls.
How many scientists does it take to establish that a consensus does not exist on global warming?
The quest to establish that the science is not settled on climate change began before most people had even heard of global warming. The year was 1992 and the United Nations was about to hold its Earth Summit in Rio. It was billed as - and was - the greatest environmental and political assemblage in human history. Delegations came from 178 nations - virtually every nation in the world - including 118 heads of state or government and 7,000 diplomatic bureaucrats. The world's environmental groups came too - they sent some 30,000 representatives from every corner of the world to Rio. To report all this, 7,000 journalists converged on Rio to cover the event, and relay to the public's of the world that global warming and other environmental insults were threatening the planet with catastrophe.
In February of that year, in an attempt to head off the whirlwind that the conference would unleash, 47 scientists signed a "Statement by Atmospheric Scientists on Greenhouse Warming," decrying "the unsupported assumption that catastrophic global warming follows from the burning of fossil fuels and requires immediate action."
Now a new theory suggests the catastrophe was set in motion 15 million years earlier, deep in the Earth. On the edge of the molten outer core, a plume of super-hot material began rising through the mantle, upsetting convection in the core and throwing the planet's magnetic field into disarray.

It is the coldest start to December since 1976, when the average was 33.4F (0.8C).
Arctic and continental winds have dominated the weather since mid November, bringing colder conditions than normal.
