Hi I'm Carl Azuz thank you for taking 10

major winter storm strikes america
hitting states like texas
especially hard if that sounds familiar
it's because the country is weathering
back-to-back winter systems
and that's put about 125 million
americans more than a third of the u.s
population
under some sort of weather alert most of
these warnings stretch from texas to new
england
the winter weather has affected states
from washington to michigan as well
many of the people who are feeling it
the most are those whose power has been
knocked out
several million of them in texas and
authorities are warning people to be
especially careful if they're trying to
warm their homes without the power on
they say portable gas powered generators
should never be used inside
fireplaces wood stoves and combustion
heaters should only be used
if they're vented correctly to the
outside cars
should never be left running inside a
garage even with the garage door open
all of these raise the threat of carbon
monoxide poisoning which has been blamed
for several of the deaths that have been
reported during these winter storms
in the southeastern texas city of
houston scores of people waited for up
to six hours
to get inside a shelter that was set up
at a convention center
volunteers brought food and warm
clothing to help others whose
electricity and water weren't running at
homelined up in their cars for fast food in
some cases waiting four hours to get to
the drive-through
last year natural gas and coal generated
more than half of texas
electricity these plants need water to
stay online
and with water facilities frozen in the
cold temperatures some companies can't
produce electricity
wind turbines like these are responsible
for around 25 percent of texas energy
production
we told you yesterday how some froze up
or shut down during the storms
experts say the turbines weren't
prepared with antifreeze for instance
for the frigid weather
nuclear power accounts for about 11
percent of texas electricity
and at least one nuclear unit shut down
because it also needs water
so the result of all of this texans are
stuck in the cold
millions of texans are once again
spending a brutal
and dangerously cold night in their
homes this is because there are still
millions of people without electrical
power in their homes this is the third
night in a row that power is still out
to millions of homes across the state
because of this winter storm that blew
in sunday night into the state
there is another storm expected to come
through on wednesday
as well but the question remains when
will the electrical system be back up to
full strength
to get people the ability to warm up
their homes
and as hard as it may seem to believe we
just don't have a clear answer
at this point we spoke with the chief
executive of the texas power grid on
tuesday
who said that they'd hoped to restore
power on tuesday and wednesday
but that is not clear that it's not
clear that that's going to happen
we've heard from local and state
officials who seem to suggest that there
are other issues at play here
the governor is saying that natural gas
pipelines
are frozen so it could take longer to
restore
that power and and get that power into
the system so that people can warm up
their homesthe bottom line is here we just don't
have any answers as to when
the full strength of the the texas
electrical system will be back up
and running so that millions of people
don't have to spend another night
in the dangerous cold once again ed

ten-second trivia where would you find
the largest known
impact crater on earth south africa
siberia
antarctica or mexico
south africa's greeda fort crater is the
world's largest
known impact crater
an impact crater as the name suggests is
formed when something like an
asteroid crashes into something else
like earth
this more recent phenomenon was not
caused by an impact
but it is one of 17 craters that have
mysteriously appeared in the russian
arctic since 2013.
scientists don't know for sure how this
happened they do know the holes about a
hundred feet deep
picture three city buses measured end to
end and after
it was discovered last summer they flew
a drone inside the crater to capture
dozens of images
from which they built a
three-dimensional model that helped
researchers to hypothesize
this methane gas somehow accumulates in
the permafrost of siberia
they're not sure whether the gas comes
from deep inside the earth or near its
surface
but they believe that as the methane
builds in a cavity of the ice it forms a
mound
and that mound grows until it finally
explodes blasting ice and other debris
and leaving behind the crater
scientists are using computer technology
to try to predict where this will happen
next
these craters appear in sparsely
populated areas they're usually
discovered on accident by
reindeer herders or during helicopter
flights of the area
the world's oceans are also vastly
mysterious places according to national
geographic more than
four-fifths of the sea has never been
mapped in detail
and scientists have gathered more data
about the surface of mars than they have
the depths of our own blue marble but
this is what oceanographers strive for
to not only learn about the waters
covering the earth
but to share that knowledge with others
and a non-profit company is using
virtual reality to do
just that here's how it brings people a
3d view of the deep blue sea
once you break through the surface of
the ocean
it really opens up for you
you will see so much life it's colorful
it has so much movements
it feels like a transition into another
world
my name is erica woolsey and i'm a
marine biologist with a specialty
in coral reef ecology i'm also a leader
of the hydras a non-profit devoted to
ocean
understanding we want to promote
ocean connection so that what we know
about our ocean can turn into what we do
to protect it
not everyone can access the ocean i want
tofind ways to bring the ocean to everyone
because the ocean is just too
good not to share
the technologies that we use include
virtual reality
that can recreate what it's like to be
underwater
has anyone found the turtle yet through
our vr film immerse
we've taken nearly 1 million people
virtually diving since june of 2020.
since the pandemic we're taking even
more people
virtually diving sometimes as people
that are divers
and really miss what the coral reefs
used to look like sometimes it's people
who have never been
to the ocean and think it's scary but
that experience makes them wonder if
they can try
in order to collect this incredible 360
footage that makes you feel like you're
diving
we use a very specialized camera
and it is basically 13
mounted cameras in an underwater housing
when we stitch this footage together we
can create this 360
effect where you can look in all
directions right now
we're not only disconnected from our
ocean but also each other
so these virtual dives are a wonderful
tool
to connect us more to our natural
environments
no matter how far away from the ocean
you live
you rely on the ocean so much of our
foodmost of the oxygen that we breathe comes
from the ocean
having this experience even virtually
can make you feel a lot more connected
wherever you are you can put on a vr
headset
and feel like you're diving
because it's that human connection to
thesebeautiful and often inaccessible places
that lead to positive change
tips for setting a new guinness world
record take a look at the old record
and then build something 91 percent
bigger that's what the makers of this
snow maze did in manitoba canada their
latest creation covers about 240
000 square feet that's a larger amount
of space than four football fields
they started building it in mid-december
and just opened on valentine's day
and they plan to keep it open through
march weather permitting
until they know which path to take some
may feel like the walls are closing in
there are a labyrinth of possibilities
and wrong choices can lead to dead ends
but it's something built for both
amazement and amusement finding the
quickest way to the exit is kind of the
whole point because after all making
your way through a maze is a rite of
passages
I'm Carl Azuz want to give a shout out
to our viewers in the netherlands today
we heard from the american school of the
hague it's great to have you watching
and we hope everyone watching has a
great rest of your thursday
