Canada to earn its ‘Great White North’ moniker this winter

Much of Canada is set to plunge into an old-fashioned cold, snowy deep-freeze this winter, according to the latest forecast from The Weather Network.

The return to a classic Canadian winter follows an exceptionally mild one last year brought on by a strong El Nino phase. The contrast could make the frigid temperatures and heavier snowfalls feel especially jarring.

“For most Canadian cities, count on doing more shovelling than last year,” chief meteorologist Chris Scott told CTV News. “It may not be a brutally cold winter all the time, but compared to last year this is more of a classic Canadian winter.”

Ontario and Quebec can expect a bigger dose of the white stuff than last year. This will be particularly true in the lake-effect snowbelts where lingering warm water in the Great Lakes is expected to fuel snow squalls late into the season.

Atlantic Canada is also supposed to see an uptick in active weather. Storms are expected to vary between those that push up from the Great Lakes to systems that push out to sea. The mixed bag of storm tracks means a variety of snow, ice and rain will be on the menu.

The Weather Network is calling for normal snowfall across the Prairie Provinces. However, Alberta’s foothills and high prairies could see a bit more than usual.

Western Canada is expected to see above-average precipitation thanks to a stream of Pacific moisture wafting across British Columbia. Snow conditions should be favourable in the Rockies, and the Lower Mainland will have an increased chance of flurries compared to recent years.

Ironically, the only places that are expected to be consistently warmer than normal are in the North: the Northwest Territories, Nunavut, Yukon and parts of northern Quebec and Labrador.

Environment Canada thinks the plunge in temperatures may not come until January, offering plenty of time to stock up on thermal socks or book a flight to someplace warmer.

“We think the first half of this winter will be milder than normal,” said Environment Canada climatologist Dave Phillips. “The toughest part will be the end.”

Old Teeth Tell New Stories: One archaeologist created a prehistoric GPS for tracking ancient humans.

If you want to retrace the life of a person who lived thousands of years ago, than you need to start at the beginning.

You don’t just have teeth in your mouth, but you have around 32 fossils that tell a microscopic history of health. Scientists have found that even the old, discarded, not-so-pearly whites of people that lived thousands of years ago tell a story about them, too.As the hardest substance in the human body, tooth enamel is different. It offers a window into life histories.

When our tooth enamel forms during childhood, it incorporates elements from the local environment, including the dust we breathe from rock layers beneath our feet. On the Other hand, Bones change every few years. Our bones soak up materials around the area we’re buried like a sponge, as we decompose.

Ashley Sharpe, doctoral student of University of Florida, created a map for determining the native place of ancient people and animals in Central America. Archaeologists will use the map to match lead found in bedrock from specific locations to a curious source: millennia-old teeth.

Pinpointing birth and death locations will help Sharpe track and other archaeologists track the movement of prehistoric Maya and potentially solve mysteries surrounding the civilization’s origins and eventual demise.
