i'm rico hizon in singapore, the headlines: a warning our planet's future is in jeopardy at a crucial summit on climate change, with a call to action from the bbc presenter and naturalist david attenborough. if we don't take action, the collapse of our civilisations and the extinction of much of the natural world is on the horizon. washington mourns for a former president, as the body of george bush senior arrives in the capital where it will lie in state. i'm ben bland in london. also in the programme: signs of a truce in the us—china trade war, as president trump says beijing has agreed to cut tariffs on american cars. and a rapturous reception

as michelle obama visits the london schoolgirls she first met when she was first lady. good morning. it's 9am in singapore, 1am in london and 2 in the morning in poland, where the naturalist and broadcaster, sir david attenborough, has described climate change as humanity's greatest threat in thousands of years. he warned, it could lead to the collapse of civilisations, and the extinction of ‘much of the natural world'. he was speaking at the opening ceremony of the united nations—sponsored climate talks in katowice which is being attended by around a0 heads of state and government. david shukman reports. it's been a year of deadly fires and record heat. and also, new warnings from scientists about the dangers

of living in a world of rising temperatures, with the risk of many more scenes like this. a social media campaign has gathered voices from around the world, calling on governments to take action. please welcome sir david attenborough. the campaign spokesman was given a rare chance to appeal directly to this global forum. right now, we're facing a man—made disaster of global scale. our greatest threat in thousands of years — climate change. if we don't take action, the collapse of our civilisations and the extinction of much of the natural world is on the horizon. there was applause, but not much. maybe because tackling climate

change is so difficult. poland, like many countries, depends on coal. we went down a mine to see the grim process of getting it out. thousands here think a green future threatens theirjobs. what would you say to a polish coal miner about his future, given what's being discussed here in this conference? well, all you can say is that things change. and there's a process of history which is now moving to its end. and that you will have to find... your children will have to find new ways of living. so as the conference continues, there will be some tense arguments over what to do. with so many countries represented here, and thousands of delegates, together with incredibly complicated negotiations, it's easy to forget what this is all about. so, let me show you what's happened to global temperatures.

there's one stripe here for each year since 1850. blue is for below average, orange is for above average, and the most recent years are the hottest, so they're marked in red. and the big concern is where the world is heading next. stronger storms and the sea—level rising are growing threats. small island states feel the most vulnerable. what kind of effort must be put into rebuilding when your entire economy is wiped away? imagine, what if the entire economy of ireland or england was washed away, where would you start? and that is the reality of climate change. tomorrow is a special holiday for miners here and, although they're celebrating, they're angry about the talks. at this conference, one miner told us, "the ecologists should take a look at themselves and ask who contributes more to the world, them or the miners?" but as the evening coal fires burn,

each one pollutes the air. scientists say this must be phased out. it'll be a huge challenge. let's take a look at some of the day's other news. a debate on britain's brexit deal is due to start on tuesday — but it may be delayed over suggestions that the government has broken parliamentary rules by not publishing legal advice in full on leaving the eu. earlier, the british government's top legal adviser addressed parliament to offer an overview of his advice. the attorney general, geoffrey cox, also said the legal changes in britiain‘s relationship with the eu would take some time. the gradual removing and loosening

of tyres that we have with europe for 45 years, will take time to work out. this agreement and eu withdrawal at already passed by the house, allow for the necessary time and legal means for that process to u nfold and legal means for that process to unfold in a peaceful and orderly way. also making news today, a huge clear up operation is happening in paris after the worst civil unrest in france for several decades. there were more than four hundred arrests as protestors, calling themselves the "yellow vests", clashed with police around some of the city's famous landmarks. they want president macron to scrap his increased taxes on fuel, something he is adamant he won't do. the international olympic committee has given the organisers of the 2020 tokyo olympics a glowing report on a visit to inspect progress. that's despite a row over whether the preparations had gone over—budget or not.

ioc president thomas bach heaped praise on the city's preparations with a year and half still to go. the first manned soyuz flight since a failed launch in october, has successfully docked at the international space station. astronauts from the united states, canada and russia arrived safely following a six—hour flight. the trio will spend the next six—and—a—half months aboard the station. a previous mission in october was aborted when a booster failed, forcing the two astronauts to make an emergency landing. the us president says china has agreed to remove tariffs on imported us cars, a day after the two countries agreed to a temporary pause in their trade dispute. beijing hasn't confirmed mr trump's announcement, which he made on twitter. at the 620 summit on sunday, china and the us agreed they wouldn't increase tariffs for the next 90 days,

to allow for talks. earlier, i spoke to the bbc chinese service correspondent in washington, zhaoyin feng, and asked her what reaction there'd been from beijing. it is good to be with you, rico. so, beijing has offered very limited details regarding the deal reached during the donald trump meeting in argentina. it is likely to be moved to downplay china's compromises in the negotiations, and to save face in front of the domestic audience. regarding trump's latest tweets, we haven't heard from beijing, they have not echoed or rebutted donald trump's claims about china agreeing to reduce or remove tariffs on american vehicles. and on weibo, the chinese equivalent of twitter, some chinese dissidents pointed out that the chinese government has steadily lowered its tariffs on american vehicles for several years, just increased it to 40% to retaliate trump's tariffs, and some simply comment that they are looking forward to buy an american vehicle at a much cheaper price. absolutely.

but how much trust is there in china that trump will be good with his promise that he won't impose increased tariffs over the next 90 days? so, in a nutshell, the chance is pretty low. in the spring, beijing thought it has reached a deal with the us treasury secretary mnuchin in washington, but the deal was very shortlived, for only ten days, before the white house announced a new round of tariffs. so this time beijing has been very cautious. probably this is one of the reasons why beijing has not published many details about the deal. and how have the markets in china reacted to the developments over the weekend in argentina in the meeting between donald trump and xijinping?

so the major markets rallied for this news coming out from the trump—xi meeting. the indexes in hong kong and shanghai skyrocketed 2%. in the us, the us markets also had a celebration. the dow rose over 400 points in a day. the enthusiasm is dimmed a little bit because of uncertainties remaining, regarding how the two countries will solve their underlying differences. i talked to some people in the us government industry earlier today. they said initially they were relieved by the news, but they have already started to worry about what will happen after the 90 day deadline. zhaoyin feng there, speaking with rico a little earlier. a memorial ceremony is taking place in the us

congressional building in washington for the late president george h w bush, who died on friday at the age of 94. mr bush served as the forty—first us president, from 1989 to 1993. his funeral will be in the capital on wednesday, before his burial in texas. our reporter, rajini vaidyanathan, is on capitol hill. here this evening members of congress have been paying tribute to america's 41st president, george hw bush. his casket arrived just as the sun was setting. it was carried up the steps here with a military guard of honour. receiving his casket were the bush family, including his son, the 43rd president, george w bush. then there was a ceremony which took place in the rotunda of the us

capitol building, where we heard from a number of senior politicians, the speaker of the house, paul ryan, the senate majority leader, mitch mcconnell, and the us vice president, mike pence, who all paid tribute to a politician who has been remembered and revered across the political spectrum. george hw bush was a president who devoted his life to public service. he served as a congressman, he was head of the cia, chair of the republican national committee, the us ambassador to the united nations, all of that before he became vice president to ronald reagan and then of course took the top job himself, serving one term as america's 41st president. rajini, we can see pictures now of the scene of his coffin draped in the stars and stripes, as people file past and pay their respects. ijust wonder, are they making preparations, and bracing themselves there, to receive hundreds, possibly thousands of people from across the us, who may come to washington wanting to do the same? that's unclear at the moment, ben, but we know that the first people

to pay their respects, aside from the dignitaries, will be people who worked for george hw bush in his white house, members of his staff. tomorrow, people who worked on the desert storm operation in the gulf war will go into pay their respects. as you have rightly said, this will be open to the public later this evening. members of the public will be allowed to come in and pay their respects. it is unclear how many people will attend. certainly george hw bush represented a politician that many say belonged to a very different era. you have people across the political spectrum paying their respects. he was someone who developed and held friendships with people from the opposite end of the political spectrum, too. even though he was beaten by bill clinton, he was good friends with the clinton family, with bill and hillary clinton,

and indeed with the obamas, both of whom will be attending his state funeral here in washington, dc on wednesday. his son george w bush will be one of the speakers at his funeral, and donald trump will also be attending with first lady melania trump. you're watching newsday on the bbc. still to come on the programme: facing extinction — we'll take a look at australia's poor record in protecting species. also on the programme, we'll take a look at what's called socialjetlag — having a life—style that conflicts with your body clock. it's quite clear that the worst victims of this disaster are the poor people living in the slums which have sprung up around the factory. i am feeling so helpless that the children are dying in front of me and i can't do anything. charles manson is the mystical

a major climate change conference has opened in poland with a stark warning to delegates not to be the generation to betray humanity. the body of president george h w bush, has arrived in washington, dc, where his body will lie in state in the us capitol rotunda. let's take a look at some front pages from around the world. china daily leads on president xijinping's meeting with the argentine president in buenos aires. a number of agreements were reached between the influential developing nations, and the paper calls their cooperation ‘a visionary blueprint for the future'. the japan times reports on the probe into former nissan boss carlos ghosn being brought into question. mr ghosn is suspected of serious financial misconduct, but the paper quotes security analysts who question the timing of his arrest and whether other figures were complicit. the international edition of the new york times carries

the story of a robot caregiver, entertaining lonely residents at a nursing home near paris. zora the robot has reportedly been a hit with patients, but the paper says there's still a long way to go before robotics can replace a human touch. those are the papers. now, you may never have heard of this, but you are likely to suffer from it. socialjetlag — a syndrome biologists believe is brought on by having a life—style that conflicts with your body clock. so, if you are used to a lie—in on weekends, and get up early for work during the weekdays you might be leaving your body confused. researchers in the us may have found a way to measure socialjetlag in people by monitoring their twitter use. michael rust has been researching the concept at the university of chicago. he explained to me the key problem. we think socialjetlag is

unhealthy. you have three days when you are not working, —— free days, you are not working, —— free days, you are not working, —— free days, you are effectively living in one time zone, we face the demands of work you are living in a different time zone. it is correlated with obesity, cardiovascular disease, and an adverse metabolic profile. how much of the blame can we are to be to our devices? we're not sure. this study used twitter as a tool to study used twitter as a tool to study technology different parts of viewers. we do not using a smartphone itself is part of the problem. it is how we follow people. i wonder whetherfor problem. it is how we follow people. i wonder whether for people who are watching there is, those who work shifts, and then, for example, they think i will catch up on my sleep at the weekend, what can they do to mitigate those effects that you mentioned earlier, things like the risk of cardiovascular disease and isa risk of cardiovascular disease and is a long? i think the best thing you can do is to try to get your

body clock is closely aligned as when you have to get up for work as possible —— and so on. there are frequently have seen in the 21st century all get worse in industrialised civilisation. we spend less time outdoors, we sleep less, and the sleep has shifted later and late in the day. exposure to bright sunlight is the primary queue that your clock uses know what time it is. in the morning, get exposed to daylight. michael rust and social jetlag, speaking exposed to daylight. michael rust and socialjetlag, speaking earlier to ben bland. it may be known for its distinctive wildlife, but scientists in australia say the country is one of the world1s worst for protecting species from extinction. a series of reports have called for more action to protect hundreds of endangered native animals. more from our sydney correspondent, hywel griffith. unique to australia, loved around

the world, koalas are just one of the world, koalas are just one of the country's native animals vulnerable to extinction. finding one in the wild isn't easy. kelly started tracking koalas in the blue mountains after realising that very little is known about population numbers. the only thing that is clear is that they have fallen. this tree. there he is! hello! is directly you happy for trade, so we lost millions of animals per year exported for pelts. -- is. animals per year exported for pelts. —— is. and then over time you have new diseases, chlamydia has been introduced, probably from domestic animals, you have habitat loss, that is the key thing. koalas like the same soil as people, so they have lost a lot of land to develop it as the human population grows. lost a lot of land to develop it as the human population growsm lost a lot of land to develop it as the human population grows. it is not just koalas. build the human population grows. it is notjust koalas. build these were once a common sight across the arid interior. but the introduction of cats and foxes lead to their

extinction in some states. we found this one at die zeit —— bilbies. across australia in the past two centuries, 10% of native mammals have been wiped out. what scientists are have been wiped out. what scientists a re really have been wiped out. what scientists are really worried about is the impact of the last few decades, which has left 500 species under threat. and extinction can come very quickly. 90% of these river turtles we re quickly. 90% of these river turtles were killed by disease within just two months. conservation scientists warn a quarter of australia's threatened species aren't even being monitored. the country has been complacent. we are the first generation to really understand the impacts we are having on our natural resources and oui’ impacts we are having on our natural resources and our environment and we are probably the last ones that can do something about it. 21st century conservation is actually about people, not animals. conservation is actually about people, notanimals. so conservation is actually about people, not animals. so we are dealing with human behaviours, with well entrenched norms of practices in the way is that people live and
