we have areas we have to change this culture and one of the fortunate ones we can leave an establishment on how tight but all these people and on the majority of these illegal of us are talking about just good hardworking people that want to live the american dream like our ancestors these are going to refugees are terrified that they may be forced to return to me and mark. so hoping that heritage president biden launches a global summit seen as a rare opportunity for cooperation with china. the united states sets out on the road to cut their greenhouse gases in half and half by the end of this decade.

the rommany watching observer lines my headquarters here in doha also coming up russia says it's pulling back troops from its border with ukraine but the government in kiev says it's still monitoring the situation closely. also india reports a global recall of more than 314000 new current virus infections as patients struggle to access of spittle beds and oxygen supply lines. welcome to the program u.s. president joe biden has pledged to cut america's greenhouse gas emissions by more than haul by 2030 he made the announcement at the opening of a virtual white house climate summit that's brought together leaders from 40 nations in an effort to speed up global efforts on the verge of

a looming crisis by america will not wait to act the cost of doing nothing is only growing by maintaining those investments and putting these people to work 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 fair and cleaner for the entire planet. you know these steps will set america on a path of nigeria a mission economy by no later in 2050 but the truth is america represents less than 50 percent of the world's regressions no nation can solve this crisis on our own as i know you all fully understand all of us all of us and particularly those of us who represent the world's largest economies we have to step up not china is

the world's biggest emitter of greenhouse gases and is peach to the summit president xi jinping pledged to phase down coal consumption by 2030 china has committed to move from carbon peak to carbon neutrality in a much shorter time span than what might take many developing countries and that requires extraordinary hard efforts from china supporters being given to encourage peaking pioneers from localities sectors in companies were strictly controlled coal fired power generation projects we will strictly limit the increase in coal consumption over the 145 year plan period and phase it down in the 15th 5 year plan period let's go to washington d.c. well white house correspondent kelly health that is standing by for us i was listening into that conference of course america is back and it wants to regain much that it had lost in stature and leadership during the past 4 years good way to

start doing it kimberly. well there is no question that that is one of the major themes of joe biden the u.s. president's message to the world leaders in this global climate summit that the united states after 4 years of climate denial when it comes to the science regarding climate change under president donald trump that the united states is back but this is also the united states hoping to lead by example the u.s. president joe biden believing that the announcements of the planned cuts for missions that he has charted out that this is something that can challenge other global nations given the fact that this is really something that he sees as an existential threat so that is why he has laid out these ambitious goals and he's hoping that others will do the same but it's not just the international message that joe biden is projecting he's also projecting and was very much

a speech aimed at the domestic audience because his plans for a global or rather a green economy here in the united states have not been met with sort of overwhelming enthusiasm particularly by some conservatives in the united states who believe that now is not the time given a pandemic and high unemployment here in the united states this will cost jobs and so this is the challenge that he not only has to win over the international leaders in the international community but he also has to win over his own constituents here in the united states who are skeptical of his message and of course completely took out the message be trying to be get through that message to the to the u.s. public but the world itself and its national communities also really need to to feel that the u.s. is back in the game van needs a just as important and i suppose president biden has that really difficult job as

you say not just to deal with the domestic audience but with international partners that really need the u.s. at this moment in time. well it's really interesting because if you listen to all the speeches if you listen to joe biden speech if you listen to chinese president xi speech speech and if you listen to russian leader vladimir putin's speech you can tell there's tension among those 3 nations particularly when it comes to russia and china they both of those leaders took digs at the united states if you will given the fact that we heard from vladimir putin that he was kind of saying look at we respect our international agreements sort of taking a swipe at the fact that the united states under donald trump pulled out of the paris climate accord and he also referenced kyoto in the case of the chinese president xi well he talked about how he believes that he can reduce his admissions

and his nation in a shorter time span than other developed countries air quote there that's a reference to the united states so you have to remember that there are great tensions in the backdrop between these nations and so well they are committed or at least pronouncing these commitments to one another on this global challenge of tackling climate change. with this backdrop of tensions over other major issues between the united states very quickly i should mention not only has there been the tit for tat of tariffs between the united states and china but more recently under lattimer putin and joe biden just last week they were putting sanctions on each other so these are the challenges that they have as they commit to this global challenge of fighting climate change they still have their individual differences to work out and that will play a major factor in all of this could be how could i want times correspondent thanks very much completely. now russia has ordered its armed forces to withdraw from a shared border with ukraine ukraine says it's now monitoring the situation in its

eastern regions very closely tensions have been rising between the 2 countries after moscow mass tens of thousands of troops on its border with ukraine russia maintained it was just a military exercise when a smith has more from moscow. this was a shy jeweled withdrawal of troops a russian defense minister 2 weeks ago said that today the exercises that they were conducting on the border with ukraine they've always called them exercises would end and true to his word he has ordered the troops back to their bases within russia it was of course an enormous vast exercise in terms of manpower in the build tree and the build up of military in crimea occupy crimea and along the border with ukraine with pretty much president for an exercise of russia says it was in response to provocations from nato from nato members but they did say this was an exercise about exercises comes to an end today and those troops will be going

back to their bases so russia nothing this is nothing out of the ordinary however what does begin on saturday until the end of october is a restriction to naval passage passage for naval vessels through the courage strait this is the straits that separates eastern crimea from western russia and it gives access to western ukrainian ports russia is saying that it will allow merchant shipping through the strait but from saturday the 24th they'll be no access to naval vessels either to ukrainian naval vessels or to knesset vessels invited by ukraine 3rd party countries now there is a treaty between russia and ukraine the says both parties are supposed have equal access to this area russia says it's closing access off until the 31st of october for exercises but that's a very very long time for exercises to take place but

a smith charles translator he's a mario poll in ukraine any reaction from the ukrainians where you are charles. very little so far the spokesperson for the ministry of foreign affairs said that ukrainians were monitoring the situation it's fair to say though that there is a lot of distrust despite this announcement from the russians that there is going to be this gradual pull back now of that military deployment a huge money through deployment we've seen in recent weeks around the borders of ukraine and crimea. certainly you know that the people that you speak to on the ground in and around the areas that are deeply affected by this conflict. have very little faith in what the russians are saying and certainly we've seen evidence in the last couple of days of of shelling in some of these

areas very difficult to say who opened fire 1st if you like but it's certainly an exchange of fire this has been in the last few weeks the biggest escalation of fighting along some of these borders since 2070 proportionally more ukrainian soldiers killed at the beginning of this year than they were at the same time last year earlier today we were out with the maritime guard here who work closely in cooperation with the navy and just building out what it was saying about this announcement of russia's closing up the courage strait which connects the eyes off sea with the black sea we were out on patrols and speaking to some of these men who were saying that they've seen some of the 15 warships that russia has moved into the azoff sea in recent days now the as all see it grima maritime agreement is shared between russia and ukrainian and ukrainian side this was signed in 2003

and so the russians do have a right to be operating their navy be operating on. time see in the eyes of see sorry but as this navy officer told us today he said well that was all b. and well that was all fine. but full the war in for the war with russia started in 2014 not agreement signed in 2003 but it's a very different scenario having russian warships so close to the east coast obviously having suffered well going into the 8th year of this conflict now so what's the situation going to be like for people living very close to the border you've visited the area on several occasions trials. yeah that's right certainly in the last couple of years i have been here for 4 years now and it's a noticeable change in and around the ukrainian side of the contact zone big

improvements really to the infrastructure of some of the towns in that area but as i say we witnessed quite heavy shelling 23 days ago around the town about. a couple of days ago we were out in a village close to here mariel people we spoke to. an elderly couple in a village who said that you know fairly often they were hearing shells being fired both from the ukrainians and the rebels very close by they felt very unsafe most of the rest of the village had had left in recent years they said the ukrainian army had had taken control of some of the houses there that had been left empty so there is this great sense of uncertainty and of course in the context of what's happened in the last couple of weeks the skill ation everybody very nervous that could get even worse so i can only imagine that the people in these areas will be

looking at this announcement from the russians with a sense of relief but still also as i say a sense of distrust. that in ukraine thanks very much charles. well still ahead here on al-jazeera. i'm. on the edge of what is known as the great green wall an ambitious project to plant trees from west to east africa in an attempt to stop the desert from expanding. the search for a missing indonesian submarine with $53.00 crewmembers on board focuses on an oil slick north of bali those stories after the break. start some warm in japan at the moment settled despite the northerly breezes to go 21 in tokyo and most of the korean peninsula is enjoying similar sorts of weather

there has been rain wandering around trying to get in not really make it probably heading slowly back into was eastern china and syria go should not really been ignore it it's now over the waters it's moving out of the way and apart from the swell which will hit the coast of taiwan we can we can say is just a worry for shipping now it western china there is more rain gathering and that will start to follow its way along the young scene has its one this is the spring rain started but at the moment that is the west is past part of mainland east asia if we had south internees is seeing probably the end of the radio season there are significant showers in kind of montana but maybe more of this in this line that goes back towards sumatra peninsula malaysia and catches cambodia that's the wet season if you like persistent rain sometimes heavy and we've seen a lot of such rain and snow in northern india and there were tears running down towards nepal there are few thunderstorms in the forecast brief in new delhi that

it becomes quite a once again in the northern plains remain pretty hot. jump into the stream there is a lot going on in this and julian and global community when i talk about the misinformation i think we are more afraid than we are aware be part of the debate don't ever take anybody's one word because there's always a difference when no topic is off the table we have been disconnected from our land we have been disconnected from who we are good enough to heat a new big part of today's discussion this dream on out is the era.

of the back you're watching all just there with me so rob a reminder of all top stories president joe biden opened the global climate summit with 40 world leaders by pledging to cut half the coal and petroleum fumes that the u.s. pumps out some it takes place earth day is marked around the world but most of the marches and rallies that usually take place have been canceled because of the pandemic. russia has ordered its armed forces to withdraw from a shared border with ukraine ukraine says it's not monitoring the situation in its eastern regions closely tensions have been rising between the 2 countries after moscow must tens of thousands of troops on its border. india has reported the world's largest increase in corona virus infections since the start of the pandemic more than 314000 new cases were registered but he

government that it was going to be responsible for the lives of these people if it didn't wake up to this situation now we also have a similar situation it's not as bad but people are dying elsewhere in the country because they can't get to hospital beds or to ventilators it's why the government is now importing 50000 metric tons of oxygen to send to 12 of the states that are the worst affected. indonesia's navy chief is warning that oxygen supplies on a missing submarine will run out by saturday 53 crew members on board the cayo. 402 went missing during a military exercise on wednesday and there's been no contact since an oil spill has been spotted in the area and the sound was detected around the time the vessel disappeared just a washington from jakarta authorities are still looking to the areas to the north coast of bali it's believed the vessel was around 96 kilometers from the coast of

bali when it went missing authorities say that they are still looking at that specific area and in that area they did see what appears to be an oil slick they saw that just hours after the vessel went missing yesterday and they're still looking into whether that oil slick has anything to do with the submarine and if it does does it indicate that there was some sort of fuel leak or is there potential that the crew may have deliberately released some of the fuel experts say that the latter option is more unlikely than the 1st but there are questions about the condition of this vessel and how possible it is to find its location in this particular vessel was built in the seventy's in germany and has been in operation in indonesia since 981 but authorities say it recently underwent regular maintenance and refurbishment in south korea and is in good condition a home going investigative journalist has been convicted and finds the charges

areas in central israel the missile was fired as israel was carrying out air strikes inside syria israel's military says it's attacked missile batteries in syria in retaliation perry fawcett has more from west jerusalem. yes this was a sizable blast that was heard here in jerusalem nearly 100 kilometers away from the site and this missile fell close to israel's dimona nuclear reactor in the town of or near the town of claim that there were air raid sirens there the israeli military confirming those pretty immediately after the explosion and of course with the context of what's been happening in recent weeks the very high tensions between iran and israel over iran's nuclear program and the attack ascribed to israel sun 10 days ago on the iranian what's hance enrichment facility there were immediately concerns that this could have been potentially the next step in that

shadow conflict a very dangerous and escalatory one however the israeli military says what took place was a syrian anti-aircraft battery targeting. the incoming israeli ordnance which overflew its target and went all the way over israeli territory and exploded in southern israel that is something that there is some precedent for those similar events in 2017 when such a missile was intercepted by israeli air defenses and other incidents in 2019 when a missile ended up in northern cyprus so that is something that has happened to thaw in response israel has continued its strike operations on syrian territory targeting syrian anti-aircraft batteries so for now the israeli military saying this was not a deliberate attack near this very important site rather an accidental one. now the u.n. watchdog says iran has replaced damaged machines at its uranium enrichment plant
