Hi I'm Carl Azuz for CNN 10. Welcome to
our viewers around the world
this week we're starting with a forecast
for a type of season
that doesn't begin until june 1st why
are we looking so far ahead because the
season we're discussing is the 2021
atlantic hurricane season
and there may be increased interest in
this year's forecast because
last year's season was a doozy the
atlantic hurricane season covers named
storms in the atlantic ocean
the caribbean sea and the gulf of mexico
scientists have been keeping records of
these storms
in these regions since 1851. storms
can form outside of the season and
several did last year
and a major record that was broken last
year was the total number of systems
there were 30 named atlantic storms in
2020
the previous record had been set in 2005
when there were 27 named storms
what's interesting as far as the names
themselves go is that there are only 21
of them pre-selected for each season
so in 2005 and 2020 scientists used the
letters of the greek alphabet
alpha beta gamma delta for the storms
that came after the first
21 names they're not going to do that
again meteorologists announced this year
that if the 21 original names get used
up
a supplemental list with more names will
be used
instead of the greek letters forecasting
the number of hurricanes is kind of like
forecasting the weather
it's not an exact science last april for
instance
colorado state university initially
predicted there would be 16
named storms there turned out to be
almost double that
and there were seasons when the group
initially predicted more storms than
their turned out being
but unlike the u.s government which
predicts a range in the number of
hurricanes
colorado state predicts a specific
number and cnn 10 contributor tyler
malden tells us what that is
the atlantic hurricane season is right
around the corner carl
early predictions say it could be
another busy one
the six-month season runs from june 1st
to november 30th
researchers at colorado state say this
year will be above
average in their preseason outlook the
team calls for 17 named storms
eight of which will become hurricanes
and four of those becoming major
hurricanes
an average year would feature 14 named
storms and seven hurricanes
this is based on the newly released
30-year averages from 1991 to 2020.
noaa the national oceanic and
atmospheric administration
will publish its prediction in may it's
important to noteresearchers are simply trying to
forecast how many systems will form
a busy season doesn't mean a lot of land
falls nor does a
quiet season mean fewer landfalls
a tropical system receives a name once
it reaches a wind speed of 39 miles per
hour
a named tropical storm then becomes
categorized as a hurricane when its
winds hit 74 miles per hour
the intensity is measured on the saffir
simpson hurricane windscale which ranges
fromone the weakest to five being the
strongest
here's a look at this year's names do
you see yours on the list
the names come from the world
meteorological organization and
are reused every six years you can
easily find the list for upcoming
seasons on the internet
if a storm is significant enough the wmo
will retire the
name and replace it with the new one
10 second trivia which of these is not
anactive current nasa mission to mars
reconnaissance orbiter
insight maven or sample return
the keyword here is active mars sample
return is a proposed mission but it
hasn't gotten off the ground yet
[Music]
counting its rovers its lander its work
with the european
space agency and its orbiters the
spacecraft
zipping around mars nasa says it
currently has
eight active missions to the red planet
on monday morning earth time at 3 30
easternthe small ingenuity helicopter was set
to make its first attempt to fly on the
red planet if all went according to plan
factoring in its construction and
operation the drone cost
85 million dollars one example of how
expensive it is to experiment on mars
and critics of mars exploration say nasa
should focus on
finding solutions to life on earth
instead of looking to establish new life
or research on the red planet but for
scientists
the mars allure is undeniable
mars its blood red color
inspired the romans to name it after
their god of war
the ancient egyptians called it the red
one the chinese
firestar now with nasa aiming to send
humans to the planet in the 2030s
the question many have is why
mars is our second nearest celestial
neighbor and the fourth planet from the
sunat its closest it's 30 million miles
from earth
it's the second smallest planet after
mercury yet has the largest volcano in
the solar system
olympus mons mars has no known resources
that would be valuable enough to send
back to earth
it's bombarded by solar radiation and
has dust storms that cover the entire
planet
which raises the question why
governments and private enterprise are
spending billions of dollars on getting
there
perhaps the most intriguing reason is
the search for extraterrestrial life
in 1976 nasa's viking 1 became the first
spacecraft to successfully land on mars
on board was apparatus designed to
detect life
chemical soil tests were initially
promising but doubts were raised and it
has since been discounted that life was
discovered by viking one
yet it still supercharged the debate on
whether there was life beyond our planet
and what it means for our place in the
universe
conditions on mars indicate life could
have existed and in 2018
nasa's curiosity rover found organic
matterlike methane in rocks organic molecules
could be the food
for life or they could be the product of
life or maybe they're from something
altogether different
such as geology or meteorites that were
deposited into the lake
nasa's perseverance rover which touched
down on the red planet february 2021
is actively testing for signs of life
too the samples it collects are due to
be returned to earth for analysis
in 2031. nasa's motto for hunting
extraterrestrial life
has been follow the water and in fact
water did once flow on mars in abundance
enough to cover a fifth of the planet
and the water still exists
today the planet's two polar caps are
largely made up of ice
if it melted the water could flood the
entire planet to a depth of 35 meters
the presence of water also makes the
prospect of human settlements on mars
possible
even though there are only small amounts
on the surface
as well as drinking it nasa is exploring
using water as protection from solar
radiation
and as a possible fuel source but
martian settlements won't come cheap
in the 1960s and 70s nasa's apollo
programcost 280 billion dollars
that hasn't stopped people like spacex
founder elon musk from pushing the idea
history is going to bifurcate along two
directions one
one path is we stay on earth forever and
then there will be some
eventual extinction event the
alternative is to become
a space bearing civilization and a
multi-planet species
which uh i hope you would agree that is
the right way to go
musk floated the idea of terraforming
the red planet to make it more habitable
even suggesting this could be achieved
by dropping nuclear bombs on it
historically the idea of terraforming
has been met with skepticism by members
of the scientific
community many doubt there are enough
resources on mars to do it
then there are all the unexpected
benefits of attempting to go to mars
the last space race brought a boon in
technological innovation
that gave us things like gps ear
thermometers camera phones
cat scanners athletic shoes and leds
perseverance rover is just the latest in
a series of missions to mars that spans
decades
and each new step towards the red planet
has brought the potential for
a better understanding of our own there
may not be a lot on mars
but it's the unknown and the adventure
of getting there
that might just merit the price tag
for 10 out of 10 this kind of thing
might not attract much of a crowd in
parts of britain or australia
but when officials shut down a highway
in idaho
for a rancher and 2 500 sheep to cross
well this has become a tradition in the
gem stateevery year about this time the rancher
moves his flock from his farming
community to the foothills near boise so
they can munch on grass there through
the summerhighway 55 stands in their way so with
the help of handlers and some working
dogsand under the watchful eyes of excited
onlookers the flock makes its way to
greener pastures
well why not it's a sight to shape of
course folks are going to make a boat
peep about it
of course some might think the animals
are on the lamb and want to lamb baste
someone for this
but the rancher's not trying to pull the
wool over anyone's eyes he just wants to
flock to where the grass is greener to
keep his sheep in cheap shape it's
really not a bad idea
hey want to give a shout out to
creekside high school today the one in
surrey british columbia canada
thank you for your comment on youtube
