it's growing. and young people clearly have the solution to their jobs. let me 70 percent now everyone on t.w. . this is d w news and these are our top stories u.s. president joe biden has pledged to cut us carbon emissions by hauff by 20 it's the most ambitious climate protection targets ever set in u.s. history around 40 countries are taking part in the 2 day virtual climate summit. hundreds of mourners have been remembering dante right the young black man shot and killed by police at the small bright was killed during a traffic stop near minneapolis the officer who shot him apparently by mistake has

been charged with manslaughter. and life on mas nasa scientists are one step closer to making that possible the perseverance rover has converted carbon dioxide into pure breathable oxygen for the 1st time nasa ames to do this on a large scale it could pave the way for human exploration on the red planet this is g.w. news from but then you can find much more news and analysis on our web site d w dot com. or. the u.s. today pledged to cut its greenhouse gas emissions in half by the end of the decade

a movement to brand the u.s. as a leader in fighting climate change but even if america keeps its word europe will still be ahead america's real leadership was hosting today's climate summit bringing more than 40 world leaders together including rivals such as russia and china on any given day you probably won't find moscow or beaching on the same page as washington or brussels today was an exception to save our climate will require turning that exception into the rule gotham berlin this is the day. we need a planet well beat on grab a look. at the beast and this is the decisive decade this is the decade let's make decisions tell of or the worst consequences of the

climate crisis we. can to discern just a bit at loss and species loss across private lives that's made this. also coming up for the past 2 weeks the west has watched and worried as russia positioned thousands of troops along its border with ukraine today must go said it's withdrawing those forces the increased tensions they're going nowhere we get the right. no idea if that will be a war or not but it definitely doesn't depend on what we are not that easy if the both of them yes they're raising tensions now but i still think this is all about political bargaining but it's just get that. one to our viewers on p.b.s. in the united states into all of you around the world welcome we begin the day with the u.s. taking a place again at the table of climate change the white house today hosted

a virtual climate summit and pledged to cut its c o 2 emissions in half by 2030 for the u.s. it was an ambitious step and an about face from the policies of the trump administration the u.s. was not alone today japan canada and the u.k. also promised tougher targets by the start of the next decade india russia and china did not make any significant pledges today in fact chinese president xi jinping said he expects those nations that have been industrialized and polluting the longest to make the deepest cuts 1st but that will not stop the process of global warming entirely a new report by the reinsurers swiss re concludes that if the world fails to meet the goals of the paris climate agreement there will be massive losses in g.d.p. china's will shrink by 25 percent the us 10 percent but even if all of the goals are met the global economy will still shrink by 4 percent the damage there are

already baked in this is becoming more and more an effort at limiting and mitigating and not reversing. but in kicked off his address with a sobering summation of society's climate sins from burning fossil fuel to inaction in the face of species extinction to rampant deforestation and air pollution in contrast to his predecessor biden said it was time for action and laid out his ambitious climate goals to the some 40 participating heads of state and government . the united states sets out on the road to cut greenhouse gases in half and half by the end of this decade that's where we're headed as a nation and that's all we can do if we take action to build an economy that's not only more prosperous but healthier fare and cleaner for their entire planet since

the industrial revolution the earth's climate has warmed by around one degree celsius it could reach 2 degrees by the end of the century we are at the verge of u.b.s. we must make sure the next step is in the right direction. much of the younger generation has been calling for global c o 2 emissions reductions for years now for it seems their voices are being heard. china will strive to peak carbon dioxide emissions before 2030 and the chief carbon neutrality before 2060 china has committed to move from carbon peak to carbon neutrality in a much shorter time span than what might take many developed countries. at times the conference seemed like a contest of the powerful all lauding their own efforts to save the world the e.u. committed to become climate neutral but 2050 earlier this week terminates

chancellor said this applied to germany as well you know i know this is a herculean task because this is nothing short of a complete transformation a complete change of the way we do business the way we do work in the fall of guns is on the tuesday in the street in the bra most taking part seemed happy to have the u.s. back on board to face this massive global challenge that morning. or let's go now to washington and our bureau chief newspoll she's on the story for us tonight going to need to use enid's we know that president biden's policy here is the thinking it's ok if we disagree with china and russia on geopolitical issues but we have to agree with them and work with them on climate change how was that policy playing out in diplomacy you have to consider different approaches to different topics friend i mean president biden understood that the world only can fight climate change to gather and as he knows that other countries soften more and more

from the effects of climate change he uses this topic actually to find some common ground besides all the ongoing conflicts in ukraine or with regard to community in china what about biden's own commitments today he pledged a cut in greenhouse gases in the u.s. by 50 percent by the year 2030 does that go far enough. well when you think how important big cars still are in this country and how powerful the lobby of the auto industry is and how wasteful after all the american culture is in itself friend i think this is indeed a very huge vive besides this concrete figure i think it is even more important if fide and will fulfill those promises that fighting the climate catastrophe will play a huge role in every single bill he puts out there so we shall see which role it

really by the end of the day plays in his huge infrastructure plan you're in washington you know as well as i do that politicians promise a lot is president biden in a position to deliver what he is promising. indeed he has promised a lot of during his campaign and he actually keeps promising a lot but on the other hand he really puts out a lot of very very concrete and specific builds but we have reported a lot on that print his problem is that his political majority is so thin and might even shrink. the mid-term election so he really has to work with the republicans and that limits his political power you know in his we report many times that climate change impacts poor countries the most but that is only part of the story what is climate change already doing in a rich country like the u.s. where you will. the last year was devastating for the united

states when it comes to climate change i'm sure that many of our international viewers will remember the images of the wyatt fires in california where the smoke grieving changed the sky of the collar of the sky to 2 already but it's actually not only droughts and fires which are a growing threat to the united states it's also hurricanes and the raising sea levels so we brought this report from the coast of virginia. a neighborhood is drowning tidewater gardens is a public housing project in the middle of north fork on the coast of virginia due to heavy rain falls and rising sea levels it is prone to extreme flooding the local infrastructure is too old and can't cope with the water. the city wants to upgrade the area and rebuild housing but the big question is what will

happen to its current residents they are being forced to relocate. corrina or a ford has lived here for 9 years and is one of many fighting these plants. corner like now form jennifer cage she. braces if any. relocating has huge implications for her family this specially her 2 kids they still don't know when and where they will be moved to a. high school next year so if. they want to know. i'm preparing them for they're ready mentally but. that. is so many questions answered.

sarah black is representing her and others in a lawsuit against the city and actually like the area that is tide water gardens is not becoming marshland it's being redeveloped for other people probably wealthier and whiter people and the emphasis are for upgrades which are desperately needed in part because of climate change are going to be done for other people just not this community and i think that's really heartbreaking a different approach is needed. but it is really important when looking at issues of climate change to look at issues of social justice and racial justice and how climate change is negatively impacting minority communities and how we as a country can best protect them the city of norfolk has refused to comment on the ongoing relocation process meanwhile the next flooding is already on its way to

tidewater gardens. it was quite heartbreaking to see how powerless the people the people who live in tidewater gardens feel and that they really do have the feeling that fighting the climate change is really used as an argument for trying traffic ation so what we experience their brand it really underlines the importance when looking at issues of climate change change that one also has to look at issues of social justice and racial justice it's all interconnected as you point out there in that story it is conducted a mini survey of u.s. media earlier today the dairy chauvelin verdict race relations police and gun violence dominate climate change and this summit did not on your travels used do you get the sense that people in the u.s.

today see climate change for the acute threat that it is. well fire doesn't care if you vote republican or democrat and water doesn't care what color your skin is so my feeling is friend and i'm travel this country quite a bit the more people are affected by climate change the more people understand that something has to happen and as you pointed out early in your report it is also a generational question because no doubt the now 16 years old or so they will feel the outcome they will feel climate change where he harshly so i think it's fair for them to ask everybody to help them to have a good future ahead of them and then this well that's right and what kind of world will we be leaving behind in this poll in washington is as always thank you.

along russia's border with ukraine the troops are pulling back today russia said it is withdrawing its forces which have been massing near the border with ukraine for the past 2 weeks the announcement came from russia's defense minister as he was observing military maneuvers in crimea today russia has been holding massive drills in and around the territory that it and from ukraine back in 2014 troops have also gathered in russia close to areas of eastern ukraine currently held by pro russian separatists so what was russia trying to do by moving some video of its forces near ukraine the defense minister said it was all an exercise to show that russian troops are always ready to respond. she is a i consider the goals of the snap check of readiness fulfilled its coverage in us through it is that the troops have shown that defense capability and i decided to complete the drills in the southern and western military districts. the years the

general staff had to have military districts an apple in fall says must stop the return of troops to the points of permanent location from april the 23rd. grader issue with lupus than it is look at. where those exercises have drawn criticism from nato and western governments which have described them as a provocation they've also led to a rise in tensions in ukraine the w's ukraine correspondent nick connelly has been to the city of mariupol close to the russian border the people there have been preparing for the worst. only a few of the older children here can really remember a time without war since conflict began 7 years ago these children have seen parents lose their livelihoods and often their lives now they found stability in this christian children's home in a city of half a 1000000 people just a matter of kilometers from the frontlines.

dropping everything and getting to safety in a hurry this drill is all about russia's troop buildup along ukraine's borders these kinds of exercises are once again part of daily life here for some of the teenagers though there is little need to practice. back in 2014 i spent 2 months living in our sailor with my mom and i never thought the war would reach us i remember watching t.v. it all just seemed so unreal like something from a film then our neighbour's house was hit and we ran date into the cellar for cover and we were just listening to it all. it was really scary i'm scared the house of collapse around us and we'd be trapped in there. back in 2014 frontline suburbs of residential neighborhoods and dozens of casualties nowadays the front line is still just as close to the city and its residents just as vulnerable ukraine's army has made significant strides since 2014 but at sea where russian forces are also

now massing ukraine is still at a significant disadvantage. the crew of this ukrainian coast guard vessel a tight lipped willing to tell us that they've seen increased russian activity in recent weeks they're ready and willing they say to respond to any possible provocation whether or not they expect all out war they refused to say. if the security service is just now as genuine. hope as the outnumbered in these words is always. controlling access to the sea the sea of. grain nor its allies can send in reinforcements. for all the military and diplomatic posturing every day life goes on can often seem oblivious to the tension being paid to this region by the outside world. i have no idea if that will be a war or not but it definitely doesn't depend on. raising tensions now but i

still think this is all about political bargaining it's just. everyone here in mariupol has a sick case packed with money and the same in case they need to leave in a hurry everyone. with being afraid that something people here in eastern ukraine tell you time and time again desperate for a chance to live a little even if that would stop them preparing for the worst as they like the rest of the world try to understand what it is like to meet putin and his troops have in store for them. and my 1st guest tonight is kurt volker he was u.s. special representative for ukraine between 20172019 under former u.s. president trump he took part in negotiations involving russia to secure a cease fire in the breakaway regions of eastern ukraine ambassador it's good to see you again it's good to have you on the program again how would you answer those people who are what is vladimir putin's in the game with ukraine.

well i think it's a it's a don't mean to attack the question but it's a misunderstanding to think that putin thinks in terms of end games putin thinks in terms of position how does he amass power and influence and how does the apply that over time opportunistically without any end in sight and i think what he's done with the accumulation of military force here is to demonstrate that he has substantial military capability and the political will to act if he wants to and he's trying to demonstrate on the opposite side that the west is not willing to use force and is not why didn't match that and therefore ukraine had better watch out so what do you make then of russia's announcement that it will pull back its troops is putin finished this time beating his chest. i think we have to really think hard about what tolling backed the troops means what the

defense minister said as to their points of permanently cation it's not clear that those are the same places they came from you may be moving them to new permanent locations more find out and secondly some of the things that he's done such as declare parts of the black sea and parts of the sea and as of off limits to foreign vessels those are meant to continue through october we'll see what happens even after that but that's actually a long commitment he's also as part of this deployment put new types of forces into the crimean peninsula paratroopers and phoebe's landing vehicles he's moved things from the caspian and say bierria to the region of russia we'll see what actually departs it will see what he leaves there will see what changes he believes that he's as a result of this going forward one of the things that was in your report was the suggestion that this has a political motive in terms of negotiations or posture in addition to military and

i think that's exactly right i think what he is trying to do is to demonstrate that the minsk agreements from russia's perspective as not produced what they wanted which is an independent portion of ukraine that prevents ukraine from becoming part of the west from developing economically and so forth and so he may be more king and in political steps and will follow on from this military deployment you can imagine for instance recognizing as independent the 2 so-called peoples or publics donetsk people's republic that russia is set up inside ukraine you could imagine some announcement this weekend about a closer union with delegates or maybe even unifying the russian dollars an armed forces which would create a new northern front for ukraine so i think there's a lot yet that we haven't seen that we may still see and i'm wondering about sadr is there a subtext here to the message that putin is trying to send is he trying to tell us that ukraine will never be allowed to join nato for example.

well he's certainly declaring that that is his intent that he does not want to you claim to be a successful democracy i think that's the most important thing because if you cranes a successful democracy and prosperous country why isn't russia so the 1st thing is to block ukraine part of that is blocking ukraine from european union if you remember the my down in 2014 and nothing to do with nato it was about young coaches desired to prevent ukraine from signing an association agreement with the e.u. which brought people out into the streets and it was there the fact that young coaches fired upon the people and then fled the country that cause putin to then want to overturn. the situation crimea today there to meet in the east and then finally yes i think nato is a part of it but it's a it's a secondary or 3rd just given that we were struck that russia have said that the

ukrainian president mr selenski is welcome at any time in moscow for talks shouldn't president to linsky should he take up president putin on that offer. well let's get the sequencing here right president zine ski proposed to president putin that he will go to moscow to talk about peace in the don't buy us putin responded that he'd love disease olinsky any time but not to talk about the dots newton says that this is an internal ukrainian issue and that selenski needs to talk to the so-called separatists this is a device that russia is using to misc portray to create dissin from asian and make it appear that there is an internal ukrainian goblet with separatism spontaneously decided to to fight against the ukrainian government that has fought a false narrative russia invaded ukraine created the separatists arms them trains

them equip them controls them controls in hand pixilated ministrations there as well and then is trying to force a let's deal with them as if russia has nothing to do with the problem so his refusal to meet with zamansky about the don't bus is really the significant part of that statement and you say that putin is telling it is using this fall to narrative president biden also says that he's now in the white house what should the by did ministration do on the ukraine issue. well the most important things that we need to be doing and it's not only the united states it's germany is nato it's the e.u. we need to be taking action to demonstrate our capabilities and our results so for example we're going to be conducting military exercises in oman next week anyway on a long scheduled basis which involve ukraine in the exercise somehow to show that when we are willing to try to work with ukraine we have security assistance that we provide to ukraine the by the administration is looking at accelerating some of

that its systems which is a good idea united states has not had a bastard in ukraine for 2 years or special envoy for ukraine for year and a half i think putting some names out there and getting people on the ground quickly would be another positive step we could be announcing it advances what sanctions we would apply if russia were to launch a new normal terry offenses we haven't made those kind of statements yet there are a lot of things we could be put in the impulse to is the war in putin about what the consequences of his actions could be and best i've got about 45 seconds so if putin gets his way he could be in power in russia until the year 2036 there could be 3 more u.s. presidents between now and then i mean he definitely wins in continuity of the ability to plan accordingly or do you see it differently well i see him stop i don't see how he can leave power instead a lot and so i think that he is looking for a way to preserve his hold on power nationally and through any through the power

ministries and need cation of force inside russia but another aspect of the story is the new volley situation that putin would not normally prison opponent and arrest $11000.00 protesters he's done it in this case was demonstrates that he's clearly concerned about his domestic position ok former u.s. special representative for ukraine ambassador kurt volker ambassador it's good to have you on the program we appreciate your time and your insights tonight thank you . thank you. well the day is almost done but the conversation continues online you'll find us on twitter either d.w. news or you can follow me of brant goff t.v. i remember whatever happens between now and then tomorrow is another day we'll see you then everybody.
