penguins iconic animals of the frozen cotton

now a new study indicates melting sea ice caused by climate change

soon we haven't gone one calling emperor penguins

would still be room for a large law firm and other species

which shows that that the fancy actually care

as predicted by commack when there's a population we lead decrees and

we should dramatically decrease by the end of the century

scientist stephanie's your movie

is the day ever articulate what study penguins around the french research

station interior on the lead

these pictures she's working with a species called the Ugly Penguin

one colony of emperor penguins in that area is perhaps the best documented

on the cockpit

french scientist and monitoring it since the nineteen sixties

in order to

analyze the dynamics of this population and see how the population relates to

changes in

c_i_s_

we need

a very long term

consistent monitoring of the population to give us the data

that we need

in the studies supported by the national science foundation

biologist how does well stephanie shouldn't be a

teamed up to model called it a rival the emperor penguin population

will likely responsibilities the arts so she would like

their breeding

colonies are all in

c_i_s_

and uh... they rely on that ice cream st louis throughout that period while

they're laying their eggs in

anywhere in their checks

and in addition and equally important to see us

provides the basis of food chain

that they're relying on

as it turns out there is evidence in the usa local record

if yeltsin how emperor penguins respond to decreasing levels of students

into nineteen seventies there was a period of about

eight or nine years win c_i_a_'s declined by about ten or eleven percent

it was an unusually warm

invent and during that period

emperor penguin population there crashed

by about

it went from about six thousand meters down to about three thousand

repairs

by the early nineteen eighties colder temperatures returned in the population

stabilized

but the episode serves as a worrisome harbinger of things to bomb

scientists predict that unless we start scaling back the amount of carbon

dioxide

all the greenhouse gases that were popping into the atmosphere

temperatures groupwise from to more than eleven degrees fahrenheit over the next

century

resulting break-up of c_i_a_ swooned wipe out the colony

generally

so it's a decline no

are higher than they keep for some time

decrease so it's uh... very high declines that puts a population that

uh...

higher risk of extinction

human colonies and other parts of the articles like this off the street

we know our mission is to make prediction that's a species that advice

it's true is that uh...

petition without

pops identifying

has ever towards c_i_s_ may be more stable than other parts

some areas

of the antarctic

more protected those areas would presumably be

places where

member penguins would have thought better chance of long-term survival

is it too late to save the

goes well says coordinated global action is needed

and soon

it's definitely true that trying to make changes in something the size of the

global climate system is a very slow process it is like trying to

too

change the direction of something like an aircraft carrier

i don't really know the answer to the question of whether it's too late for

the emperor penguin but it's certainly bodies time to start trying to do

something about it the situation won't get any better the longer that with the

way in taking action
