defendants have pleaded not guilty. our north america correspondent is in brunswick, georgia for us and sent this report. reporter: as the trial open, videos of his final moments was played. all too much for his mother who cried. sitting in front of her in the foreground here, the men who pulled the trigger. this was the video they were watching. three armed white men pursued him sankey resembled a burglary suspect. cornered him and shot and killed him. he was an avid runner who jogged through this area a short distance from his own home. the men decided to jump into their tracks and give chase. they show that one of the men involved in the killing of this 25-year-old used a racial slur as he lay dying. sadly, murals of unarmed black men have been shot and killed howard -- are dotted across this

country. in his case, he did not die at the head hands of the police but at the hands of people who could act as an extension of law enforcement and do what they want. that is after his death appears healthy police saw it. bodycam footage those two distressing to show where we see him writhing on the ground and dying and not given attention. throughout the encounter, they provided comfort to the men who killed him. they certainly don't appear to be treated as murder suspects. in fact, it was only 10 weeks later after protests and the video of the killing was tak viral that the three men were even arrested. they were charged and are now on trial. >> you can intentionally kill

somebody in self-defense and not have committed murder. he would be not guilty. >> this till self-defense if they chased him? >> that is because they were attempting to execute a citizens arrest. >>'s case is already led to the scrapping ofhe civil war era citizens arrest law in georgia. before the trial started, his mother told me that somehow, good would come out of this tragedy. >> i hope that in losing a mod -- ahmad, people that look like him will be allowed to jog, run or do whatever and be free. and not to be worried about being chased with guns and killed. reporter: for the trial taking place in the city that is majority black, it would only be one black juror. it appears easier to overturn lost and to change the attitudes of those that contributed to his

death. anchor: i am joint now for more. we really heard the prosecutor honing in on that point in your piece that the defendants did everything based on assumptions. what will be their strategy and at is the defense saying? reporter: we heard opening statements from both sides. it started with the prosecution. delete prosecutor did not explicitly talked about the fact that they assume thing because of his race. that, i'm sure is where some of the evidence goes in the future. she did not say they acted on those assumptions and presented evidence that the men who killed him he had not done anything illegal at the time. they chased him, cornered him, shot him and killed him.

we also heard from the defense who insisted that these men were acting to help the police. the argument is whether they had the right to do that. where they will go during this trial is to suggest that the sun who was involved here, shot ahmaud arbery because he had no choice. that is what they are saying. even though you saw in that report, everybody is arguing about how he did not have to be chased in the first lace. they felt they had a duty to chase him, acting as an extension of the police but they believe they had no choice but to shoot him. that is their argument, at least. what also happens is we saw that video of the final moments of his life. in extraordinary detail about that is that it was taken by one

of the men who killed him and it was released by those three men. it was put online. would them in a good light. that video in the end is what ultimately led to their arrest. anchor: thank you so much. thounds of young people took part in a march today in the scottish city of glasgow, calling on world leaders to take action to tackle global warming speaking at a mass rally, greta thunberg said they did not need any more distant nonbinding pledges calling this assembly a failure. we have been following the days events and sent us this report. reporter: a rare opportunity for protesters to loudly deliver a message within earshot of the global decision-makers gathered in glascow. greta thunberg through inspired the movement have said they have

failed to deliver. young kids inspired by her have drawn their own pictures of her. >> i know she put out a sign and then everybody else started following her. reporter: how do you talk to children this age about climate change without scaring them too much? >> we gotta let them know about plastic, pollution, air pollution. reporter: because the government announced measures to put clement at the heart of education, kids were skipping school to take part in this protest. your sit -- what is right that sign? >> they are saying we had to do this now. we gotta do this now but they are not sorting it. >> they are making promises they can't keep. reporter: do you think that's what they are doing? promises they will keep? >> yes.

this happened a lot. people say they will do things and they don't make enough change to make it impact. >> they are listening to what we have to say and trying to make a change. reporter: are they trying to achieve the same thing as you? lower emissions and save the planet? >> i don't know. they are trying but we are trying harder. reporter: there have already been comtments to reverse deforestation and promise more money than ever before to tackle climate change. greta thunberg doesn't seem very impressed with the progress so far. what do you think? >> it is fair enough. it is been 26 years and no progress has been made. carbon emissions keep increasing. we need action. reporter: she dismissed this as a pr exercise. >> this is no longer the climate conference. this is now a global north green wash festival.

visitor center. since then, it has completely retreated around the corner and you cannot see it at all. these days, if you want to see the ice, it is a tough hike up and over a high pass. this is all that remains of the once mighty glacier. they are melting all over the world, potentially affecting millions of people who depend on ice for their water supply. >> if we didn't have glaciers, there is no more drinking water. no more hydropower potential. especially for agricultural needs, we could have water only during the winter and not the summer. reporter: back in the village, he is struggling to come to terms with the idea that his home will soon be go. >> the town means a lot to me.

to commit to deeper carbon cuts to drive down the long term of emissions. at the moment, if you analyze the promises they have made, we are still on an increasing trend then bending down to decrease omissions. the target according to the climate chances is we should cut them by around half by 2030 where at the moment, we are at an increased trend of going up 15%. it's fair to say that we are way off track. as i say, the idea wasn't to solve it in one go. we got a draw ambition and get the welcoming the onboard to this huge project which is driving down emissions, moving away from fossil fuels and towards renewable sources of energy. anchor: your reports showed the effect on alaska but rising temperatures also play a role on the widespread global change in weather patterns as well don't they?

reporter: the accelerated warming we see here in alaska which is warming about twice as fast as the rest of the world. if you think about it, the way the weather system works is that it is about differential temperatures. it is hotter at the equator than up north. air rises and mixes with colder air from the northern hemisphere. that generates the weather system. the winds that drive the systems around the world. if you raise one temperature more quickly than the other, you will have a different weather pattern and that is what we see happening. that river of air that moves around the arctic circle call the jetstream is wobbling. it is trapping weather systems which is why we see these colder winters. the east coast of america, the heat them in canada. they wrecked these process of changing weather systems around the world. anchor: thank you so much.
