time to bundle up y'all arctic cold is
coming to north america
and CNN 10 is explaining that as we get
underway this february 4th
I'm Carl Azuz. There's this thing called
the polar vortex we've told you about
beforeaccording to meteorologists it's not
accurate to say the polar vortex is
coming to get you
but it can cause frigid air to invade
the continent
and that's exactly what it'll be doing
this weekend scientists describe the
polar vortex as a low pressure air mass
that's located near the earth's north
and south poles
it keeps the arctic air bottled up in
these areas but in the winter months
the polar vortex can become unstable and
allow some of that frigid air to spill
south
and a single blast of this arctic air is
the main reason why
every state in america all 50 including
hawaii
will see below freezing temperatures on
monday morning
86 percent of the country 235 million
people will be affected
forecasters predict high temperatures in
the midwest to be 15 to 20 degrees below
normal
some parts of wisconsin could see
temperatures of 25 degrees below
zero fahrenheit that's one of 16 states
expected to see sub-zero temperatures on
monday
meteorologists don't know how far south
the cold air will reach
but some forecasts show cities like
atlanta georgia seeing their lowest
temperatures in years
the dangers of all of this especially up
north frostbite within 30 minutes if
people are outside and not wearing the
right kind of clothing
freezes and ice jams on rivers are
possible snow that comes before the cold
could ice up on roads causing traffic
problems
forecasters say unusually cold
conditions are expected to remain in
place for the next
10 days ten-second trivia

at some point last year schools in all
50 states were closed to in-person
learning because of concerns about the
coronavirus pandemic
now according to edweek.org partial
closures have been ordered in five
states
in-person learning has been required in
four states
and the 41 other states allow in-person
learning though many governments have
districts decide whether they'll be open
and what their restrictions are studies
have shown that in communities where the
virus isn't widespread
or where masks are worn and regular
testing is done
schools can be open without causing more
problems
but some researchers are concerned that
where there is widespread transmission
there could be more exposure in schools
and that kids and teachers who catch
covid there could spread it through
their communities
there have been concerns raised by
teachers about their risk of catching
coronavirus
there's a debate raging about whether
virtual learning is as effective as
in-person learning
and experts have voiced concerns that
school closures may be taking a toll on
students mental health
so there's no nationwide consensus on
what the right approach is
and that's a challenge being faced by
other countries as well
the holidays are long over but many
classrooms across europe
are still empty in the uk schools have
been closed to the vast majority of
students
since the beginning of the year a surge
in coronavirus cases
and new more transmissible variants have
forced the government to backtrack on
earlier promises
to get children back into school for
in-person learning i must inform the
house that for the reasons i have
outlined it will not be possible
to reopen schools immediately after the
february half term
but some education leaders say the
government has been too slow
in taking action we were saying to
government that really they should be
looking at
allowing schools to go to online
teaching in the in the last few weeks
before christmas
i think if they'd done that we wouldn't
have had quite the level of the peak
that we've had in this country
it's a similar story for many of
britain's neighbours
schools in portugal remained open even
during the country's strict national
lockdownin early january but a devastating
increase in both cases and deaths has
since pushed the government
to enforce tougher rules ordering
schools and universities
to close for at least two weeks with few
exceptions
the government says it's a necessary
measure to stem the spread
of the variant first found in the uk but
some parents feel it's too little too
late
this is a measure that should have been
taken a long time ago especially before
christmas
when there were fewer positive cases it
would have had fewer consequences for
our children's learning
the lack of consensus on whether school
closures are necessary
is evident across the continent along
with the uk and portugal
germany and ireland have opted to keep
school doors closed to students
under most circumstances italy and
sweden are taking a regional approach
allowing some in-person teaching in
combination with online classes
depending on local infection rates
while the netherlands will allow
kindergarten and elementary school
students
to return next week and in france spain
and switzerland
schools are open but with precautionary
measures in place
such as mask wearing social distancing
and staggered attendance
one expert at a leading medical journal
told cnn
that whilst there may not be consensus
on the best approach
decisions on whether schools should
remain open need to be considered
on a local level different countries
have to make decisions based on their
situation not all countries have the
samelevel of infection and i think schools
school closures
should be considered within the local
prevalence
and while some evidence suggests that
schools may not be drivers of
transmission
scientists in the uk say that remote
learning can help restrict the spread
of the virus i think schools do have a
role to play
in um restricting the spread of the
virus so
closing schools contribute can
contribute to a
reduction in the transmission of the
virus but not in silo closing schools
alone
is not going to be enough but with new
variants on the rise in europe and
beyond the issue of how soon governments
are able to lift restrictions on schools
remains a divisive topic from whether
children need to wear masks
to whether educators should be made to
teach face to face
for now there's little consensus and
little clarity
over the years we've covered some of the
more unusual winter sports like
snow kiting in norway participants can
experience speeds of
70 miles per hour and jumps as long as
500 feet
there's also ski jury or skiering in
switzerlandwhich combines the dangers of both
skiing and horse racing
cnn 10 contributor chris james reports
on a more traditional winter sport
hey carl i'm coming to you right now
from brooklyn new york which has been
transformed
into a winter wonderland according to
the national weather service
over 15 inches of snowfall was recorded
here making it one of the heaviest
snowfalls in new york city history and
for today's virtual field trip i'm
taking you somewhere
even snowier at a much higher altitude a
place that has become known
as the most magical winter destination
in the world welcome to the banff
national park in alberta canada
this little city is literally sandwiched
in between the rocky mountains
the summit of sulphur mountain is known
to be one of the most incredible spots
to watch the sunrise
the most popular winter activity no
surprise here is skiing and snowboarding
the terrain and banff is known for being
rugged and quite challenging
the black diamond trails here are not
for novices
banff is known for having some pretty
steep hills so you better know what
you're doing
before testing your luck this is one of
the most popular areas to visit
mount norquay which is a short ride from
downtown banff
this ski resort dates back to 1926. it's
loved by locals and families alike
due to the powdery snow and these
breathtaking views
this is the lake louise ski resort which
is also located in banff national park
it boasts over 4 200 acres and according
to its owners
not much has changed here at this cozy
lodge since the 1970s
this is where people can relax with a
bite to eat and a warm drink
after skiing down those ice cold slopes
yeah and speaking of cold right now it's
30 degrees outside
and although brooklyn is by no means
banff i have to say there is something
about snow thatinstantly makes me happy no matter where
in the world i am
back to you carl
just like some folks turned to
groundhogs to predict the weather
others turned to animals to predict the
super bowl and ahead of next sunday's
face-off between kansas city and tampa
baya wolverine in montana picked tampa bay
or at least he ate the cake with the
buccaneers logo but in kansas city
the goats the animals are wearing
chief's jerseys
because when they're not eating hair
they're cheering on the defending super
bowl champs
the question is whose quarterback will
be the goat that's some people's chief
concernbrady fans might be thinking the buck
stops here they're hoping his team will
tamper down the competition but even
though they're not playing at mahome
it may not matter to the chiefs if
they're not in kansas city anymore
neither qb wants to pass on the chance
to go running back to another super bowl
