sea ice in the summer. it was down to 3.74 million this year. scientists studying the sea—ice in the arctic. it just above the dotted line, which of that record from 2012. this downward trend, monitoring the ice is about 13% per decade. the national snow here is what greenpeace had to say about this. the rapid loss of sea ice in the arctic is an indicator of how closely our planet is circling down, and as the arctic melt, more heat will be absorbed by the ocean and all of us will be more exposed to the devastating impacts of climate breakdown. professor of polar observation that you see a in the uk is here from geneva. thank you very much for your time. is there any doubt that this is being driven by climate change? no, i think from our cities and also looking at climate models and observations, what we are seeing is very strongly driven by global warming from increases in greenhouse gases. in fact, the relationship is strongly linear, so we've been able to quantify that for every added to the atmosphere, you melt about three m2 of sea ice. so it's not surprising we will continue on this do

american scientists say summer sea ice in the arctic this year melted to the second smallest area sinceh is why the latest revelation is no surprise. this summer sea ice shrank to just over 3.7 million square kilometres, its second lowest level since they started using satellites to watch it 41 years ago. compared to the average from 1979 to 1990, the difference is twice the size of france, germany and spain combined. but less sea ice doesn't mean sea levels are rising. what it does mean is that it's a driver of climate change as well as a symptom. 80% of the sunlight that strikes the ice is reflected back into space. the dark ocean water absorbs 90% of it, that means the oceans heat up and arctic temperatures rise further. on average, arctic sea ice is declining by 12% a decade, which is why some forecasters say it could be ice—free within 15 years. bad news for santa and even worse news for polar bears. earlier this year, one forecast said they could virtually be extinct by the end of the century. it would also certainly mean a profound shift in the nation's marine ecosystems, which i

scientists say the arctic sea ice shrank to its second-lowest level on record this summer, due to global heating. a recent study found that the climate in the arctic is changing so rapidly, the landscape is drastically shifting from being covered in ice and snow to being characterized by open wateter ad rain. this is s dr. laura meller from greenpeace. >> thehe rapid loss of sea ice n the arctic is a sobering inindicator of h how closely our plananet is s circli t the dra d that as the arcrctic melts, more heat will l be absorbebed by the ocean and all of us will be more exposed to the devastating impapacts of the climate breakdown. amy: the trump administration has tapped a meteorologigist who questions the lilink between extreme weather r and climimate change to be t the new chief scientist at noaoaa, the natioil oceanic and atmospheric administration. ryan maui is a former scholar at the libertarian cato institute who has publicly criticized many prominent climate scientists including dr. james hansen and the united nations intergovernmental panel on climate change. texas has issusued

the arctic is the melting of sea ice that is accelerating as a result of rising temperatures we've seen unusually warm temperatures in the arctic as well as elsewhere. fires in siberia this summerpacts we're seeing >> you know, mark, this is something that obviously president obama brought you in to focus on. yesterday's developments were obviously dire and while donald trump says that it's going to get cooler, obviously the united states government and the british government don't agree with that, because they've been very troubled and, in fact, are doing as much research as they can right now on trying to figure out the long-term impacts, the economic devastation, the environmental devastation that could come if these trends we saw yesterday continue >> joe, president trump's statement yesterday is one of the biggest misuses of the bully pulpit of the presidency that i've seen. the bully pulpit of the presidency is a great teaching tool the fact is that the arctic and antarctic are changing and what happens there doesn't stay there. it impacts you in your own backyard the essence of the challenge that we face is that our children and our children's children, because of the im
