the ice in greenland is melting a lot faster than previously thought. 80% percent of greenland is coverede huge. this graph shows that greenland's contribution to rising sea levels is currently tracking on a worst case scenario. at this pace, greenland alone would contribute to sea levels rising by an additional seven centimetres above current projections by the end of the century. these latest calculations come in a new report out today. the report's release has been timed to coincide with the american geophysical union meeting in san francisco, where leading earth scientists have gathered. jonathan amos was there. we have been looking at this for a little while now. what is interesting about this report is it is really all of the polar experts on greenland who study that plays with satellites coming together and reconciling all the data that they have compiled over the years come over 25 years and saying yes, this really is what is happening. and as you say, the melting now is following projections. and come the end of the century, the there will be an additional seven cm from greenland

jesse: the president was eyeing greenland like greenland was potentially for sale.you remember this? let's listen in. president trump: greenland, it's something we talked about. denmark essentially owns it. we are good allies with denmark. we protect denmark like we protect large portions of the world. so the concept came up. extra tee tee jimally it would be interesting. it's not number one on the burner. i can tell you that. jesse: greenland is a big asset to have in the portfolio. >> i thought the president was just short of throwing in a virgin islands to be thrown into the transaction. the president's head is always on a swivel and always looking for opportunities. i don't know that we'll be adding greenland to the port foal yes any time. jesse: matt gaetz, happy new year. coming up. the craziest democrat moments of the year. a lot to choose from. stay with me. witnesses to come forward. jesse: democrats revealed their true colors in 2019. crazy, scary, angry, sometimes just weird. katie pavlich and michael loftuss are here to diagnose the problem. let's look a

over the past 25 years, they have had a centimetre of rise just from greenland. gives you some idea of what we are facing as we go into the future. what do they say about what should be done therefor? is there anyway in which this can be minimised? there is a lot of reports that come out of this meeting that i am at the american geophysical union meeting, the largest annual gathering of earth scientists. they have a lot of gloomy reports that come out about the state of the planet. the thing is, they are just scientists. all they can do is put the data out there, put the facts in front of the policymakers. those policymakers, gathered at this moment in madrid, in spain, at the annual climate conference. it is time to them to ta ke conference. it is time to them to take these facts and turn them into policy that is what they have been asked to do under the paris climate agreement, but, as our correspondence there will tell you, they are struggling to set down the rules that would enable paris to do its thing. so, yes, you can talk to the scientists but, in many wa

as you mentioned, the ice sheet b greenland, which ielieve is the second largest structure of ice onearth, is losing ice at an accelerating rate. can you give us a sense of the scale of the loss happening there? >> yeah, it's enormous numbers so it's hard to comprehend. it's abol 250 bilion tons of ice that gets lost from greenld every year and goe into the ocean, and for your viewers to conceptualize, that i want them to think aboutertd of elephants charging into the nd, and inof green order the equal the amount of mass that gets loss fromnl grd every year, you need ocean every second.rges into the these are enormous amounts -- >> brangham: every second? >> every second. so this is going right into the levels around the world, which is affecting communities that live on the coastline.t >> branghaeally is an incredibly striking and dire imact u're painting. the warming as i mention in my introduction is also causing the perm frost to thaw. we know perma fro by its n is land that is normally permanenisy frozen. whit such a concern to the mcientific community when perma forecast goes f

but scientists say the world's 2nd largest ice sheet is green in greenland is melting at a faster rate pool kristofferson is a scientist with the scott polar research institute he says warmer weather has created holes in the ice which is changing projections for rising sea levels. green and i said today the single largest contributor to sea level rise and that's why there's a lot of attention on the greenland ice it is a very dynamic ice sheet it contains the fastest glaciers and is the ice is melting the most but actually what we've discovered is. when fractures intersect lakes on the ice sheet of which there are thousands the water can rapidly flow through the fracture down to the bottom of the ice sheet and it forms what we call a moon which is essentially a big cavern a big hole and we think these moons of holes are open we can see water flowing into them even after these legs drain. in what's essentially a kilometer high water for. no it isn't good news in the sense that we can see we can see big changes in the green and ice and. having no effect on sea level rise just 25 years ag

but scientists are warning of the exhilarated breakup of the world's 2nd largest ice sheet in greenland and its likely effect on rising sea levels researchers from the university of cambridge in the u.k. say lakes on top of the stalled place here are draining through holes in the ice formed by warmer weather the water under the ice then list the glacier causing it to move it accelerate its melting we can see big changes in the greenland ice sheet . having no effect on sea level rise just 25 years ago and now it's a roughly a 3rd of all the sea level rise and planet is from greenland alone. and so there's a very significant increase and this is an increase that's ongoing and we think it's unlikely to continue so it is clearly an adverse effect. and this comes against the backdrop of the un's annual climate conference in spain 25 began in madrid with leaders urged to address what's being called an urgent an existential crisis the conference for shuttles the chilly but weeks of violent street protests forced the government to counsel countries or return to its hope the conference will incr

greenland's ice sheet is melting at an alarming grade 7 times faster than in the 1990 s. new analysis of satellite data shows it's losing about $250000000000.00 tons of ice every year and the losses are continuing to accelerate since 1902 will melt water from greenland has raised global sea levels by one centimeter that puts millions more people at risk of flooding. and time magazine has chosen gratitude as its person of the year and climate activist has emerged as a global figure over the last 12 months including a high profile journey across the atlantic by sailboat so that she can address the u.n. the news was announced while i was in madrid where the un is holding a major conference on climate change coming up next it's the bottom line this dramatic year the don't trump ends with impeachment threatening his presidency no one not even the president is a vote what next for the man hoping to win a 2nd time in power in 2020 the impeachment inquiry is a scam join us for the latest developments on al jazeera. hi i'm steve clemons and i have a question for you are you concer

will be delayed until next year meanwhile over and greenland it had sided with the us narrative as a country chose sweden's ericsson over china's huawei to supply equipment for 5 g. this decision comes as the u.s. is increasing pressure on its allies to exclude huawei from lucrative deals and after president donald trump offered to buy greenland from denmark as part of a broader strategic push into the arctic. well so much talk about the great you as m.c.a. a trade deal that is so much better than after right if you watch the show then you know that we have been critical of the fact that the u.s. in ca it's really not a vastly better deal well now new analysis from the congressional budget office shows this that the new trade agreement will actually cost automakers nearly $3000000000.00 more in tariffs over the next decade for cars and parts that will not meet higher regional content requirements over the next decade this on the heels of the head of the united auto workers union stating that the u.s. in ca will not provide more jobs to auto workers and will not return a single auto j

and had to cancel a meeting later on when the prime minister said, no, greenland was not for sale. >watching now, kaitlan, trude trudeau, stalenberg, and johnson. later on this morning should be some interesting, again, split scene momen screen moments as the meetings begin and the impeachment hearing begins back at the nation's capitol. >> that's something interesting. the president said he can't believe they're hosting this first judiciary hearing the day he's here doing exactly what you're showing there, meeting and shaking hands with world leaders, arguing yesterday they were being unpatriotic by doing so, but he doesn't think it affects the meetings or diminishes the standings. this is something president trump is used to. he's been overseas. you had the meeting with kim jong-un when michael cohen was testifying on capitol hill talking about the president's hush money payments, things like that. ite note first time he's had his domestic troubles that have followed him abroad. >> you know, indicate lan, nokk interesting yesterday, the president stand by hosting on issues. you see
