when I come here with you well we tweeted out we put on our Facebook page
we've got to get up on our on our
on our home page s
because the one thing I forgot to do is get the information off to su
or maybe louise is taking care about any of the information about we have a new
movie out
it is to its a 10 minutes long it's a short
a short piece is called last hours and
we interviewed a variety of a scientist's
about extinctions and extinction is one more than half of all life on Earth
dies and sis
so let me just share with you and and by the way here's
this endorsement for the movie just came in I
work ago
hot
somehow I have lost it
on any I've I'll find it as
by in just seconds area
now
its yeah carbon pollution from burning fossil fuels
this is al gore carbon pollution from burning fossil fuels
is changing our climate and transforming our world. from more destructive and
more frequent climate-related extreme weather events and rise in sea levels
to climate refugees clock crop failure and water scarcity
the consequences are profound last hours expertly explains how we got here
and what will happen if we don't work together to stop it it isn't needed
an urgent call to action al gore former vice president United States
and currently chairman
up the climate reality project so here's how the movie starts
consider this really only fun
go state because a man-made climate change
the room it's hard to imagine her through without life
we take life for granted but life has not always flourished here
the earth has experienced dramatic loss
his life or what we call mass extinctions five times
over the course in geologic history the each one of these events
has resulted in loss have more than half all life on Earth
at the largest and most devastating a fall
was the Permian mass extinction room almost all
place on earth despair no yet very much extinction
is in essence just the greatest crisis that life on earth is as ever so foods
by the end to the Permian mass extinction ninety-five percent of all
life on the planet was dead
and why is this important today because today
a sixth extension is underway
one that will test the survival obnoxious human civilization but
possibly up the human species
itself and it bears a horrifying resembles
several previous global warming driven events
white the Permian mass extinction I think it is certainly
extremely significant level are the main crises in the past associated with
global warming
and so with obvious implications for when the present-day
when we think of extensions we think and the dinosaur killing
Katie mass extinctions which is triggered by a sudden catastrophic
collision with the BT right
but the most deadly force behind all extensions
isn't from outer space it's from underground
underwater under the ice for trillions a
tons carbon lies in wait in the form a frozen methane
if this nothing melts and is released into the atmosphere
it will produce a sudden and massive global warming
during the Permian mass extinction greenhouse gases were released by
volcanic eruptions
in an area that is today called me the Siberian traps
these along with the Hino from the lava flow itself
warms the atmosphere of the earth by at least six degrees Celsius
that much global warming to receive more money
land animals and plants but far worse
you warm to the oceans enough that methane frozen deep under the sea
melted and was released into the atmosphere that enormous releases
methane
a powerful greenhouse gas pretty much double love love more more more meaning
killed off
over 95 percent of all life both on earth
and in the scenes it's a kind of a scary thought
but maybe one of the bests
geological Nana locks for a kinda
rapid changes in climate and 02
in the atmosphere there were going to witness now and for the next few
centuries potentially
is this and Permian time when rule I
who as you know that culminated in
one of the day largest mass extinctions that we know of
the north coast looking at these ancient events shows this time so
global warming and the atmosphere doesn't care whether the carbon dioxide
comes from
a human activity a call from a volcano
it has the same and effects the numbers have a similar
from so the giant lava flows in siberia the the man to cum dockside to release
is very similar to this this from fossil fuel burning
I'm come to a sudden release that we have what we doing some decade after
decade to date
today carbon dioxide in the atmosphere is above 400 parts per million
a level not seen any time in the history of human life on Earth
when we are increasing a co2 levels in the atmosphere
at rates far greater than any of the most rapid
the events that happened in the deep geological past
there is no precedent for what we are doing to the atmosphere it isn't
uncontrolled experiment
as I was doctor michael mann we will %uh pick up the other
the last half of the video right after the break but the point that we're
making here
on hand and prior to that there were three other scientists
and the point that we're making here is that
there is a time bomb frozen
in the season in the permafrost out this time I was called nothing
we know of methane as natural gas
methane is the result of the decomposition of plant matter
over tens of thousands hundreds of thousands millions have years
and there are these bed its have what's called methane clathrate or methane
hydrate these beds a frozen methane
that are somewhere between four
trillion tons and 10th trillion tons
up methane around the world an estimated two and a half trillion tons in the
Arctic if you
Mel two trillion tons if nothing you have
a massive stage you're listening to the Thom Hartmann program
call 866 987 thon
so the question is if we warm how call much
must we more in the world before the oceans start melting that nothing
and then it's too late
