a trial that will go on i believe for at least 6 weeks possibly as much as 3 months time for a short break here al-jazeera when we come back reports from mali where there is complete distrust all around just days after ethnic violence left hundreds of people dead more than. hello there we're seeing some heavy rain push its way across north america at the moment we look at the satellite picture we can see the clouds here right in the northeastern parts of the states and working its way out into the eastern parts of canada now that is dragging its feet for the south and so forth in florida that's likely to be quite alone large amount of wet weather over the next few days with lots of thunder and lightning to that main system though that's going to be mostly over the eastern posited area as we head through friday and behind it it should be brightening up. for washington d.c. we'll get to around $25.00 degrees which is $77.00 in fahrenheit but the west there will be some more showers there and there's a wee pushing their way eastwards towards the great lakes region again as we head into saturday for the west largely fine and dry with having a top temperature of around 22 bit further towards the south and there's that line of thunderstorms that we were seeing over florida and just about everywhere to the south of that is very hot and humid with a few showers around so plenty more as we head through saturday and sunday i think that some of the leeward islands including percent mouth and it should be drawing there a fine day for us as a feather towards the south and so many of us he will be watching the cloud begin to thicken up once more particularly as of argentina and didn't see a year ago i that system really gets going as we head into saturday the temperatures in what is already beginning to drop away as well. welcome back a quick recap of the top stories here this hour the u.s. military has released a video it says shows members of the iranian

with her children she's the 2nd white house press secretary to serve under trump after sean spicer resigned early in his tenure. donald trump is again under fire over comments he made about accepting information from foreign governments the president told a.b.c. news that being offered damaging information on a political opponent didn't constitute foreign interference can really help get reports. u.s. president donald trump on the defensive after remarks about accepting information from foreign governments they all do it they always here at issue this interview trump gave to an american news network suggesting if he was offered damaging information on a political opponent he'd listen if somebody called. from a country norway we have information on your. own i think i want to hear if you want to kind of interference in our elections not in a difference they have information i think i'd take it if i thought there was something wrong i'd go maybe to the f.b.i. if i thought there was something wrong on thursday truck back those remarks in a tweet saying they're no different than accepting advice from foreign heads of state like the queen of england encouraged espionage metropolis faced criticism since the 2016 presidential election when he publicly asked for outside help to investigate his democratic opponent hillary clinton russia if you're listening i hope you are able to find the 30000 e-mails that are missing. in spite of that a recent department of justice investigation found the campaign did nothing illegal when it communicated with russians link to the kremlin but many democrats in congress disagree that's an assault on our democracy and a softer imagine. after talking to members of trump's own family and his former staff as part of a potential impeachment investigation prompts comments even contradict the views of his own f.b.i. chief if any public official or member of any campaign is contacted by any nation state or anybody acting on behalf of the nation state about influencing or interfering with our election and that's something that the f.b.i. want to know about republicans are also concerned if a foreign government comes to you as a public official 1st to help your campaign giving you anything of value whether it be money or information on your opponent the right answer is no i ran for president twice i ran for governor once i ran for senate twice i've never had any attempt made by a foreign government to contact me or a member of my staff and had that occurred out of contact with the f.b.i. immediately an increasing number of democratic lawmakers believe donald trump's latest statements just adds to the case that they've been baking for months that a piece of proceedings against the president should immediately begin kimberly helped get al jazeera the white house the plan to reinforce mexico's southern border with national guard troops have been delayed until the end of the month an official overseeing the force told al-jazeera an increased military presence is still weeks away as one of the conditions of a deal with the u.s. to curb the flow of migrants trying to cross over from central america the deal was struck to stop threatening tariffs on mexico. now a little known town is being used to ferry migrants across the border between guatemala and mexico low security and regular people smuggling operations have led to the area becoming a crossing point for thousands correspondent john home and join that perilous journey. you have heard of the caravans thousands of people from central america crossing into and through mexico they've attracted international attention and the anger of president trump. but there are other caravans to these ones a secret but over the last year they've almost certainly carried far more migrants than the ones in the news here they are convoys of trucks which head out from a little god to board a point between guatemala. locals say they carry hundreds of people and go most nights they controlled by people smugglers each of the charges has paid them thousands of dollars to get to the u.s. border. this one's been cool but it's the exception. is the same from another state police open a truck see the migrants packed inside and wave it on. and this is where it all begins impoverished communities in honduras el salvador and here he's shouting where people like daniel desperate to get to the u.s. . you can come good on the dream that you have a house or a plot of land an education for your children a struggle to my family but i can't give them that future here. 3 months ago he agreed to pay smugglers $3500.00 for himself and his son to take the journey they made their way to the guatemalan border town of. this uncommon shown on the mexican side of the curve points where people smugglers squeeze 50 to 70 people into trucks . you can't sit down because your scores together my son started crying because people fell on top of him they covered it up it was tough. they set off. towards miss. crossing this wide open border on the way in 3 days of going to and fro we would never ask for documents different smuggling groups take over the route as it goes into the territory moving the migrants from safe house to safe house it's lucrative but it's getting harder after pressure from president trump miscues governments tighten security along the border we've got to mother those who. want to war now there's not a lot of movement they still go but it's gone down 50 percent it's more discreet. but it is still happening we staked out the caravan in a roadside field a local contact told us he'd seen the lorries loading up shortly after we saw them heading through followed by several issues these. caravans of the coast that go in front of the christians clear so we. just wait for a chance to see it we go and we just saw the long line of trucks good post migrants told us the smugglers usually let them out just before the us border they can cross and ask for asylum daniel never made it that far the convoy he was travelling in showed up early on his uncle was killed but with nothing at home and from now away north he's already saving to go again john homan. grass' ideals. much more news of course on our website there it is on your screen the address is about al-jazeera dot com that's al-jazeera dot com. a quick

their rents a problem isn't just limited to major cities. a former governor of the indian central bank has cost doubts about the country's 1st couple. we bring you the stories of the shaping the economic woes we live in. counting the cost on al-jazeera. the un's intergovernmental panel on climate change was born from just 12 years to avoid one of trust with governments having failed so far to take effective action to combat global warming many and are looking to science and technology to come up with ways of bringing temperatures under control but what kinds of solutions being devised and how effective could they be reporter eric campbell has been finding out . we start our journey in a city moving on from carbon. few places are as eager as copenhagen to get power from wind and even in this weather from sun. know where this plane came into ditch cars that box. klaus bonded is director of the danish cyclists federation and a former mayor of the city. he's leading its push to be the 1st carbon neutral capital by 2020. i do believe that there is a strong political consensus in denmark that we need to act it's pretty cold right now but we have an extremely hot shot it didn't rain for 2 and half months here. but nothing says why is there something going on. and i think we have to realize that something is going to. copenhagen has been breaking all records in traditional ways to clean here. according to the speaker's 1631 box of cross this bridge this morning alone in the past year it's been 3519062 it's extraordinary but the problem is no matter how much we ride them or how much we recycle the matter how fast communities transition to renewables it's probably not going to be faster now because governments aren't meeting the commitments they made at the paris climate change conference to cut emissions the politics are failing which is why there's now such an urgent push to try a new technology to experiment with things that sound like science fiction but cope with the only way to ensure a secure future is a fact. the warning was sounded in october by the i.p.c.c. the un's intergovernmental panel on climate change which are working on leading scientists say carbon needed to be almost hot from 2010 levels to limit global warming to 1.5 degrees. otherwise runaway temperatures would destroy the right ballio reef droughts and hurricanes would become the norm melting ice sheets would flood major cities. but our sky mythologised jason fox a former lead all that of the i.p.c.c. says even that won't be enough. it's frightening and i'm sorry to say this but that want to have to grease global warming we still have like 2 and a half to greese of summer arctic warming and that pushes greenland beyond its threshold of viability so we still lose greenland but at a slower rate. based in copenhagen he measures our street treat for the geological survey of denmark and greenland. when we lose the reflective cover of the arctic sea ice when we lose the greenland ice sheet and the climate system globally unravels and and it's going to create the kind of problems that will make it pretty hard to govern society. the migrations the droughts so what's at risk here is is practically civilization. coral professor bach shares the frustration of all scientists contributing to the i.p.c.c. see its. evidence gathered through years of painstaking field work is often. north by politicians. politicians from governments that dismiss i.p.c.c. reports that's not conservative it's not progressive certainly it is insanity . if is the world will need massive technological fixes called geo engineering literally read engineering be good if you can just hold back what's coming. for example we can slow down melting of the antarctic ice sheet by piling up sand on the sea floor simply to block a warm currents that are already destabilizing the whole west antarctic ice sheet. other id's include covering oceans with ion filings to encourage carbon e.g. plankton. sending ships around the world to pump seawater mist into the sky to diffuse the sun's writings we have some ideas and we need to try several technologies and evaluate them and figure out which are the least risky etc 2 to get the carbon curve which is like this now to get it negative. and that all needs to happen in the next. 1020 years to start down that path it's extremely ambitious . the idea of geo engineering has excise that by scientists and industry. on the other side of copenhagen i've come to meet a prominent political scientist dr be a lumber he did it by using lots and lots of coal he's a favorite commentator in conservative media for argument against major cuts to fossil fuels and i would say look if you say to people there is another solution yes it is going to take the attention somewhat away from the original solution but we should also be honest and say we've tried the 1st solution namely ask people. could you please use the car less could you please use less energy could you please turn off your lights and it's not work for 30 years and actually there is about half a planet who's waiting to get more energy available and why do we talk to says he except that fossil fuel emissions are warming the planet he just thinks geo engineering will cool look much faster than switching to review. because it's so cheap it's very likely to happen sooner or later some indian billionaire or some saudi billionaire is going to do it all by themselves just turn it down a little bit to pre-industrial temperatures or wherever we decide to to have it and that would be essentially avoiding a large part not all but a large part of the global warming problem. so what are the most likely fixes and would they really work most of these globally ambitious projects are still on the drawing board but one surprising new technology is up and running in a place generally seen this need to retrieve. it strongly know whom of persuasion innovation. from swiss watches that never lose time just with i when i was in the country permanently a piece of small company. believes it's found what could be a big part of the solution to plug. kristoff cabal to spark a ph d. students when they decided to form a world changing company. tonight they're celebrating clime works 9th anniversary so we're still not making money so of course money is not motivation the money ration as solving a big challenge and there is probably as little as challenging as climate change. this illusion is building giant for. hands that draw in air and bind carbon molecules of the filters. the carbon free air is released back into the atmosphere the c o 2 is super heated and collect this gas i like to call it low tech not high tech and it's actually very simple the challenging part is making it work and making it cheap. in just 2 years they've opened the plants in switzerland icelandic italy. they believe they could remove 10 percent of the carbon the i.p.c.c. wants cuts. their 1st target is one percent by 2025. it's like 300000000 tons of c o 2 and that we're require a quarter 1000000 machines. but in this developmental stage removing just one tonne of carbon costs at an economical $600.00 us dollars we are confident that in the next 2 to 3 years we will have our cost and the ranch off 2 to $300.00 per tonne and in the mid to long term and that's for us 2025 to 2030 and we see cost as $100.00 as feasible. so the big question is what do you do with all this captured c o 2 well fortunately in this case there's a greenhouse just 300 meters away so half of the carbon sucked in the ferns it's piped underground of the greenhouse and turns into vegies. plants absorb carbon so the greenhouse but it's the gas this fertilizer. since it started spraying crop production has increased by 10 percent. the quicker the process can turn a profit the more likely it is to spread round the world. even in frosty switzerland there's a real sense of. urgency about limiting global warming. i came here for the mountains to climb to ski and in the alps you could see very early signs of climate change and of course glaciers are disappearing like we want to stop that if with and without climate change but the speed of disappearance is shocking. patrick hofstetter from the world wildlife fund took us out to see the disappearing place in. the alps a bore me more than twice as fast as the rest of europe over some of it was unprecedented drought. yeah that's really special for us the farmers don't know dissertation yet. the grass stopped growing soon there is a shortage in feed so they actually started to slaughter their cows much earlier and. after this really dry summer i can feel a renewed sense of urgency especially also because of the farmers now it's really accept that they are directly affected by.
