from antarctica. it measured 6,000 square kilometres, almost as big as hong kong or greater london, it slowly melted, dumping up to one a half billion tonnes of fresh water every day for four years. while icebergs and glaciers can melt in the summer and reform in the winter, the overall rate of ice loss is accelerating rapidly. scientists say earth is using i trillion tons of ice every year. the average rate of loss is increased by 60% from the i990. loss is increased by 60% from the 1990. it has tripled in antarctica as warm water speed up the the 1990. it has tripled in antarctica as warm water speed up the collapse the 1990. it has tripled in antarctica as warm water speed up the collapse of the 1990. it has tripled in antarctica as warm water speed up the collapse of lease the 1990. it has tripled in antarctica as warm water speed up the collapse of lease is the 1990. it has tripled in antarctica as warm water speed up the collapse of lease is off in that time global sea levels hav
walked out the door - and saw what looks like an immense river that covered everything, that took everything with it. my car was here, swimming about as high as the second floor. and that s not all oil spills are also a side effect of the heavy rains. this pipeline was ruptured by a falling rock in the eastern napo province. oil has contaminated two hectares of the cayambe coca national park and seeped into the river coca, which supplies water to indigenous amazon communities. back in quito, the painful struggle to find survivors continues. aruna iyengar, bbc news. stay with us on bbc news. still to come: what these adelie and gentoo penguins in antarctica can tell us about global warming. just about global warming. how fast is the ice melting? this is the moment that millions in iran have been waiting for.
a group of scientists have spent time in the antarctic hoping to find some answers. you also have satellites. 0ne animal is helping. cute and, so it turns out, pretty crucial too, the adelie and gentoo penguins are native to this part of the antarctic. unlike other animals around here, they live mostly on the land rather than the ocean, which makes them easier to track. penguins conveniently come to the same nesting sites over and over and over, year after year, and so we have this reliable signature of, you know, how many individuals are there from one year to the next and how does this play out over decades or even longer time scales. researchers came here to monitor the penguin population, collecting data from 21 different sites. parts of the antarctic have seen a big decline in animal numbers but at least around here, those figures are
are, so far away from it. the thing is what is happening is theiceis thing is what is happening is the ice is going into the ocean and ultimately reaching our shorelines, we ever we may live, whether it s great britain or the united states or anywhere else in the world, we all have shorelines in the global sea level rise is ever so slowly rising because of this extra ice that s been added to the ocean from the melting of the ice sheet. giue melting of the ice sheet. give us an idea- melting of the ice sheet. give us an idea. we melting of the ice sheet. give us an idea. we hear- melting of the ice sheet. give us an idea. we hear about. melting of the ice sheet. give us an idea. we hear about a centimetre here and a centimetre here and a centimetre there which is difficult to quantify in some respects. we were to lose antarctica terms of ice, what would that mean? if antarctica terms of ice, what would that mean? would that mean? if all of antarctica would that mean? if all of an
