russia and the united states refused to endorse its report nick clark has more on our special coverage. despite more than twenty years of climate conferences like the one under way in poland right now the amount of carbon emitted continues to rise so you can say that international political cooperation has so far failed some believe we should put more effort and money into radical scientific solutions to keep climate change at bay we focus now on geo engineering the injection of millions of tons of sulfur dioxide into the stratosphere could help limit temperature rises. when mount pinatubo erupted in the philippines in one thousand nine hundred ninety one it spewed twenty million tons of sulfur dioxide into the stratosphere the cloud mixed with water vapor and circled the globe for twenty two days. average global temperatures fell by about half a degree for eighteen months. scientists think that this effect could be mimicked

to help tackle climate change they propose a technique called solo geo engineering and recent research suggests it could be remarkably cheap. engineering is the idea that when one makes anything including the planet more reflective it cools what is underneath it's the reason why frankly when our jackets are black and in the summer we often wear white . white cools black warms for the project to work aviation engineers would need to manufacture a high altitude aircraft it would look something like this would roughly double the wingspan of a passenger jet to sustain flight twenty kilometers above the earth and have double the thrust with the four engines the main body would carry large amounts of sun blocking particles which could be fired into the stratosphere the gases would turn into aerosols and reflect part of the sun's heat scientists estimate this method

could reduce temperatures by one and a half degrees centigrade over a fifteen year period the direct engineering costs of an intervention like this would be somewhere around two to three billion dollars per year and that is very low but all are convinced some scientists warn it risks unintended consequences such as droughts and damage to crops they also argue let some governments off the hook the problem with this sort of idea is that it can encourage governments to feel that it's less urgent to do something about greenhouse gas emissions so they think that if they do geoengineering they don't need to worry quite so much about stopping fossil fuel emissions i think that's very risky. there's worldwide consensus that carbon emissions need to be cut to tackle climate change but with the effects of global warming already being felt some are looking to science to find a solution where governments have failed. al-jazeera. a volcano in northeastern

tanzania known to have all known to be natively to the native tribe as the mountain of god is showing signs of eruption it's the only known active volcano with a type of love that can move faster than a person as katherine so reports from the foothills it's now threatening nearby villages and three sites where very early humans once lived towering above everything else around the lake natch and area enough in tanzania all daniel length stands at more than seven thousand feet the local mosque community college the mountain of god for the last two years it's been rumbling geologists are mourning tearing its activity more intently because of the reasons care an eruption was imminent that threat level has since diminished but scientists say nothing can be left to chance hansen is professor at the university of director lums geology

department he says tanzania needs a working observatory center to be able to keep a closer eye on the mountain itself rather than getting information from other countries experts it has been unfortunate that even the self can tell you people from germany europe they have no information because they have been working there at the mountain there than we do disguise the know much more scientifically. than what we hear. because they have money this is the world's only active volcano that bulges out of black love a reach with a type of rock called cup borne a tight when it comes to contact with it turns white. have been recorded here since. the largest deposited one hundred kilometers away and that's a concern because a mountain is also close to important ancient historic sites like this one on the southern shores of lake notch on named the dance floor more than human footprints

left between five and nine hundred thousand years ago and preserved by debris and ash from the volcano those who live on the foothills of the mountain have watched an o. and fear the mountain of god route to life this mountain laughter rapid in two thousand and seven those who live here say it had loudly rumble for months before and when it finally spewed its love they ran for cover no one died but some lost their cattle and grazing grounds were destroyed and our psyche says it sounded like a thunder storm and describes the flowing lover as scary. i was afraid at first i thought i choked to death it was like a fire and it cooled down and became white the dust settled on our cattle and when we tried to get it off the animals it would peel off the skin. on mars king he told us immediately happened he knew what to do in line with the culture of his

community and. elders and i took up on top of the mountain that same day god listen to us and they love us stopped i don't know what we have done. communities here believe this volcano is sokrates they say they're not worried because like their ancestors they know just what to do when the mountain of god rose again catherine. in the foothills of. well. south american football will have more story after the. home.

thank you very much river plate of the champions of south american play football they beat they feel its rivals baka juniors in sunday's cup in the but to those final in neutral madrid had taken the lead in the first time from that era benedetta this practice second home goal then sure the match maybe it's the time to move but it was the same two for the same bucket the ten men wanting to go and going salamat two minutes made the numerical advantage count three one finish to river for the first couple of potatoes the match was originally due to take place in buenos aires two weeks ago but was postponed the women's has more on this for us well there has been a huge security presence around the ban about the stadium in madrid for this going full thousand police officers and on top of that we've had plain case security say that i've actually been hired by real madrid as part of them signed i will host

this couple it's a door as final helicopter is tying ahmed place vehicles and there was a ring of steel to stop supposes coming for who didn't have tickets though some of those whom ever travelled from argentina so try and get into the ground some how many would turn back at the airport many would turn back when they reached the stadium so there were less than five thousand supporters from each called an incredible guy and full of tension buck a genius of coast took the lead but river plate came back and live a plight in the end found the whites to take this trifle the bucket juniors funds will be aggrieved they didn't want this much plight i told by felt i should be handed the trophy because of the trouble so weeks ago when the bucket junius coach was attacked but the much did go ahead i'm reply of the champions this has been the i def a koan she merely icing experience for football in argentina and south american supply the final i have the two thousand kilometers away from bonus areas. and

while that burn about a stadium was hosting the couple of it's a tourist final it's usually inhabitants remedied where in action elsewhere they've been struggling wesco one million a league on sunday caravels going the only goal of that match in the win see israel madrid moving to fourth place on the table just behind city rivals atlético but the still five points adrift of leaders barcelona at the top now the city of atlanta is celebrating its first major sporting trophy in twenty three years of the lancer united beat the balkan tamils to lift the m.l.s. cup the game one hundred for football and its fans in the u.s. as joanna geyser of school reports. i. realize was late was

tiring prominence from a young thing at the high move one of the m.l.s. is the youngest team atlanta united are in just the second season in the league but the city has embraced it. was a record seventy three thousand fans watched united beat the pope and timbers in the final atlanta were perfect throughout venezuela and joseph martinez who is the league's leading scorer and m.v.p. but the one not before the break martinez then provided an assist for arjun time defender franco escobar in the second was. the two no result sealing the city's first major sporting trophy since the atlanta braves in one thousand nine hundred ninety five for team still finding its feet and a sports battling to gain a mainstream following this m.l.s. cup final provided a dream finish to the season joining us rasika just zero. the head of afghanistan's

everyday people we get them to tell their stories and doing that really reveals the truth people are still jabot outside these gates waiting for any information most of them don't know whether their loved ones are alive or dead or miami really is a nice word to the worlds meet we can get to washington d.c. two hours we can get on join us in the rest of central america about the same time but more importantly why those two cultures north and south america bits of strategic way to very important place for all to do it's a big an investigation into the real powers that control the world health organization their obligation to their shareholders completely overwhelms any consideration of public health can they be trusted with building a healthier future if their loyalty becomes questionable reason a people better product of the h one n one push isn't getting much difficult for you now a w h o has just cast who says dani returns is trust. that you trust

on al-jazeera. al-jazeera. every your. you know the whereabouts of this is a basic human rights and al jazeera exclusive the feeling say of moderate saudi journalist jamal khashoggi calls for the perpetrators to be identified and.

hello i'm the star and this is al jazeera live from doha also coming up china summons the u.s. ambassador over what it calls the violent rest of the top corporate executives. can geoengineering help stop the planet from casing we'll have more now special coverage of the global climate summit. and river plate wins the all argentine battle for south america's top club football trophy and a long delayed match moved to europe because of violence. it's been seventy days since the t.j. last saw her fiance saudi journalist jamal khashoggi alive outside his country has come to us and istanbul he was there to collect papers for their upcoming marriage

but instead walked into a death trap saudi crown prince mohammed bin feldman is being accused of ordering his now in an exclusive interview with al jazeera. says she'll fight to ensure everyone who's responsible for his death is brought to justice. i don't know if i were the sort of i want to expose the details of this horrific crime identify the perpetrators and put those who carried out the killing on a fair trial including those who ordered the hit so they get the punishment they deserve on behalf of jamal's relatives and loved ones and i say this is i'm one of them we need to know the whereabouts of his body this is a basic human right. now you know. i was convinced he was still alive i never imagined such a crime could happen in a consulate and a simple normal person can never imagine what happened in the jamal never committed any crimes and never did wrong in any way and all he did was in turkey consulate to get hold of legal papers to get married we were on the right track him and i he

wanted to build a new life and as you know he was excelled in he was in so much pain overt so to be honest i never imagined the day i'd be in this position to be honest it still hasn't sunk in yes you see me sitting and talking and talking about what happened but human can't the words fail me. see how brutality has this update from washington d.c. . this latest account of the transcript of the recordings made while jamal khashoggi was being murdered is consistent with all the information we've had so far about his death but it does out a few details because rugby's last words i can't breathe followed by multiple screams gasping and then the sound of a saw cutting its sense was also significant is the three phone cools placed by what c.n.n. says was abdulaziz tribe who is often described as a frequent companion of muhammad been the crown prince of saudi arabia and c.n.n.

says but trouble is updating someone who turkish officials say was in riyadh with a very calm step by step sense of detail about what is taking place is no panicking going on this is very very calm seen and put this to the saudis and their only query was that in the transcript they've seen and the information that they've had from the turks there's no mention of a cool that's the only thing that they're clearing about this information but the information does appear according to c.n.n. exactly the sort of information that those on call in congress have been hearing from the cia and others and that perhaps explains why lindsey graham remains so angry as he was on the sunday talk shows if it weren't for the united states said be speaking farsi in about a week in saudi arabia their military can't fight it out of a paper bag they give us nine percent of our all imports we need them a lot less than they need. this you've got to hook up to murderous regime.

america from iran quite the opposite i think hooking up with him we heard our ability to govern the region and we are expecting congress to act on three fronts in the coming week first there is the resolution to end support for the war in yemen that's primarily driven by the appalling humanitarian catastrophe that but it's gain support as a result of the murder of khashoggi in addition there are also resolutions to suspend all males to saudi arabia and to hold muhammad bin some on personally responsible for the murder of jamal khashoggi. well turkey wants eighteen suspects extradited to stand trial but saudi foreign minister has once again rejected those demands. with regards to their runs we will not hand any of our citizens to turkey even the turkish constitution prohibits the extradition of their

own citizens so why should we turkey has not provided us with the information that we need on the investigation the legal way. leaders of gulf nations have met in riyadh for the gulf cooperation council summit but the meeting has are in the exposed the increasing divisions between it six members the emir of kuwait shakes. used his speech to call for an end to the disputes and the deepening hostility through media campaigns that was an obvious reference to the blockade of cattle by three g.c.c. members saudi arabia the u.a.e. and rain all have used their t.v. and newspaper outfits to criticize the heavily kuwait is also in a dispute with saudi arabia over revenues from a shared oil field then there's the war in yemen and oman a not involved while kuwait and bahrain's roles are limited that too has made it difficult for the g.c.c. to presenting unified front saudi arabia is the largest country in the block and

has traditionally been able to drive the agenda but differences between the six member nations have weakened its position. explains. as heads of states and leaders from the gulf cooperation council met in riyadh for their annual summit a notable absence he was the emir of qatar doha instead opting to send a junior minister qatar remains under a land air and sea blockade imposed by fellow council members saudi arabia bahrain and the united arab emirates eighteen months ago it's a crisis that has brought into question the very existence of the g.c.c. nevertheless the saudi king said mounting our policies fail to even mention it during his opening remarks instead choosing to focus on iran and other issues. that you know there were tried yet you know when a region is witness of huge talent does that we all know we faced a resume and the iranian policies will also lead to stalk of these countries from it to feeling into that in the affairs of other countries this is the second summit

to take place since the blockade on qatar began the last one was held in kuwait which is the leading mediation between. two sides on that's occasion shift i mean but how middle fania tended while the blockading nation's leaders refused to show up and despite failing to solve the g.c.c. crisis kuwait's amir it seems has not given up of the night and for that we have faced a lot of challenges and on top of them there are the differences between our g.c.c. nations we need not to risk the interests of our peoples the peoples of the g.c.c. council states the g.c.c. must not be hesitant we need to keep our situation firm stand firm and we need to be able to face the challenges in our region for a core reason for the success of the g.c.c. has been in its provision of free movement of people and goods between member states with the embargo in doha on the council's inability to resolve the crisis there are those that question the future of the organization i don't think we can

say confidently that the g.c.c. is dead i think it's more realistic to say that the g.c.c. is dormant right now possibly down the road when circumstances in the region change you have different leaders in these countries possibly the g.c.c. will return to being a relevant institution in the middle east although that's certainly not possible right now given the culture crisis for the average person in the g.c.c. very little will change as a result of this summits the huge aspiration of a single currency nato style dolphin defense force and a railway network connecting member states that were once on the agenda of meetings like these seem like distant memories now instead it would appear that simply being able to hold such a summit is seen by saudi arabia and others as an achievement in and of itself. who eats. the saudi u.a.e. coalition fighting in yemen says it's issued seventeen permits for ships with food

and fuel to enter ports their aid is desperately needed in a country which the un has described as facing the wilds west humanitarian crisis twenty million people don't have enough food warring parties mess in sweden for the fourth day of un led talks with little progress on a political solution to the conflict. in the coming days u.s. senators will vote on a resolution to withdraw america's support to the saudi coalition republican senator rand paul says u.s. involvement in yemen can only have a negative impact i think that when we're dealing with arms that no personal financial dealings should have anything to do the decision and really not even the finances of the country i think selling arms should have to deal solely with our national security not jobs not money nothing and i really think that the war in yemen that we have no vital national security interest and not only that i think our involvement in this terrible war is one of the things that engender is more

terrorism as more people die from starvation as people pick up bomb fragments when a school bus is killed and on the bomb fragment it says made in america it creates more terrorism so i think it's actually a risk to our national security to be involved with the saudis and we should not be aiding and abetting their bombing of civilian areas. huawei has rejected allegations that it breached u.s. sanctions against iran the chinese telecoms giant says it communicated with u.s. government agencies on a daily basis to obtain guidance it follows the arrest of one of its top executives mango and canada on washington's request the detention and extradition process have opened yet another rift between the wilds to self economies who are already engaged in a trade war let's speak to adrian brown in beijing china's foreign ministry summoned the ambassadors of both canada and the u.s. over the weekend is this beijing trying to hit back.

yeah i think beijing in many ways the stars here is playing the victim card of the moment which it often does on occasions like this it's summoned the u.s. ambassador as well as the canadian ambassador over the weekend to once more complain that the human rights of man when joe are being violated it's always interesting to hear china complaining about the human rights of its individuals being violated when of course china is accused of human rights violations on a massive scale especially in shin jiang where up to a million muslims may well be incarcerated now in labor camps so yes that china continues to complain very for seriously about the detention of mungo but it's leaving it in many ways to its attack dogs in state controlled media to really lead the charge the global times are really sort of nationalistic leaning newspaper here in china on monday said that the arrest of mung amounted to a declaration of war by the united states so the the language the the pros is going

from from purple to crimson and i imagine that's going to continue in the in the weeks days a months ahead if she does indeed remain incarcerated of course i think what we'll really see a stronger response possibly from beijing will be if you know by march the first when this ninety day truce between china and the united states is due to expire if she is still being held and there's still no agreement on the broader trade issues between china and the united states then i think you could see possibly retaliation from beijing but at the moment china's leaders are not commenting publicly on this case they are still saying publicly that they believe a deal can be done with trump they seem to be making a separation between this case and the trade dispute but the media and also the chatter online is not ed i want to ask you about meng's incarceration there is a.
