this is the w. news line from berlin iraq that states pledged to fight climate change by cutting its greenhouse gas emissions in halt by the end of the decade president joe biden addressed the virtual climate summit with more than 48 world leaders also coming up . india's record number of covert 19 cases is pushing the health care system to breaking point hospitals are running out of intensive care beds and medical supplies to.

a morning family bids farewell to dante right the young man who was shot dead by police during a traffic stop in the united states. i'm here mohamed welcome to the program as the world marks day u.s. vice president u.s. president joe biden has made a promise to cut carbon emissions inhofe by the end of the decade if the most ambitious climate protection targets in u.s. history around 40 countries are taking part in a 2 day virtual climate summit as global warming progresses there's hope that this pledge will put pressure on other nations to do mall. 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 rapid 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 7 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 this 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 terminus chancellor said this applied to germany as well in fly no group behind 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. to follow countries on the tuesday in the steel in the of ron most taking part seemed happy to have the

u.s. back on board to face this massive global challenge good morning good afternoon well earlier we spoke to france tournaments the european commission vice president and commissioner for climate action he says the world needs to be united in the fight against climate change frankly i think we were the 1st to announce that we would be a climate util continent by 2050 we are also the 1st to assets in law this week our target 2050 but also for 20 seti which would take a steward auction of. at least 55 percent compared to $990.00 so i think we are trailblazers it was europeans will try to maintain that leadership but if we lose that leadership to the americans i frankly don't care as long as everybody's on the same page and as always everybody is committed to reach crime you try to see by the middle of the century that canada is that all flights from india and pakistan for a month to see

a growing coronavirus cases in that region it comes as india reports more than $300000.00 infections for a 2nd day the country is in the midst of a new wave of cases after a summer that saw no numbers the 4th surging to 100000 per day by september but then 40 through the winter experts say new virus variants including one that started in india are responsible for the latest surge and it's pushing the health system to the brink. ambulances lined up outside hospitals that can't take any more patients. oxygen shortages that have pitted different states against each other doctors and nurses pressed to the limit as they scramble for resources. the supplies that are coming in we saw the video and uncertain that is a lot of an engine in the system we are not able to fully focus our energies on. on the political border for its lines are hours long at testing sites after many

months of relatively few cases this comes as a shock here. the hospital being i've been waiting outside the testing center all day. and we are yet to be tested. and then the thing the whole thing will i just pray to god because if we are tested positive then where will we go we are helpless in the media. epidemiologists say india missed crucial opportunities to prepare for a 2nd wave the government didn't hire more doctors and nurses and allowed bass of public gatherings which may have been super spreader events. a sense of decency because it really is measures of a pandemic whether it was daily it's. all you can just buy them to do it's all of them started explaining from october and by any

january you saw them comment really low levels and then there was this really graphic interview with experts that we had actually at a certain unity. last week the government said it would allow a greatly expanded list of vaccines to be used but it faces the mammoth task of vaccinating a population far bigger than the european union and the united states combined. let's take a look at other stories making headlines around the world. there were violent scuffles between israelis and palestinians outside jerusalem's old city off the protesters were barred access to areas where muslims gather for the holy month of ramadan israeli police put up barricades and used stun grenades to disperse crowds the far right jewish group known as the hava chanted anti arab slogans and was prevented from marching to the area. hundreds of people have been protesting in

kuwait of the violence against women it comes off to the murder of a young mother whose complaints of harassment by a stalker was ignored by authorities protesters are demanding tougher penalties for those who assault women. have summoned the czech ambassador over diplomatic spying prague has now ordered the president to withdraw most of its diplomatic staff from the czech republic on saturday it expelled 18 russians after accusing moscow of being behind a deadly explosion at a check of munitions depo in 2014. now hundreds of mourners have been remembering dante right the 20 year old black man who was killed by police during a traffic stop earlier this month near minneapolis his funeral comes 2 days off to form a police officer derek jovan was convicted of murdering george floyd in the same city the officer who shot right apparently by mistake has been charged with

manslaughter. right right. grief was paired with defiance as mourners gathered to pay their respects to dante wright wright's family was joined by the families of george floyd and other black victims who lost their lives at the hands of police. the emotional words of right smothered that were running through the ruin you. if. we were going to be. made. that we need to go. where you want to groom you live. in beirut. he.

also in attendance were civil rights activists jesse jackson and the reverend al sharpton. sharpton is u.g. decried police brutality in a reference to the air freshener that writes mother said he was pulled over for having on his rearview mirror. we trying to get to stitch least brutality out of the atmosphere we're trying to get to stitch over a series of added mystery we're trying to get to that stage of racial profiling out of our atmosphere we come mementoes showed up as air fresheners quote yeah it's true all the routes for us to bring we carry bring in your stake in a admiral. you know he went on to profess that dante wright's death would not be a death in vain and that the fight for real change must go on there will be no

peace without justice he said. as the body of dante wright is laid to rest black lives matter protests against racial injustice continue across the country. indonesian navy ships are searching for a missing submarine with $53.00 crew on board authorities say the submarines oxygen supply will only last until saturday leading to fill is it could be too late to save lives the navy says it has probably sunk 700 meters below the surface. it's a race against time and against of the ocean's depths the k.r.i.t. 9 galah 402 may have sunk too deep to be retrieved on board are 53 crew members and very limited oxygen reserves searches are focusing on this area about 100

kilometers north of the submarine was conducting a missile firing exercise here when contact broke off officials say a power outage may have a cured causing the loss of control. the submarines oxygen reserve capacity in a power outage is 72 hours or about 3 days. so starting from when it lost contact on wednesday around 3 am it could last until saturday at 3 am. let's hope we can find them before then. indonesia has deployed several navy. neighboring malaysia and singapore have also joined the operation and other countries are offering help and oil spill and the submerged and highly magnetic object in the area of the submarine dive has rescuers hoping they're on the right track but if the submarine has sunk too deep it may be

impossible for the rescuers to operate. president. said the government is doing everything in its power to get the crew back alive. i ask all indonesian people to pray that this search and rescue operation run smoothly and easily to find k r i n n gala 402 and all of its crew in a safe condition. officials say the submarine was in a good state after 40 years of service in indonesia it may have fallen prey to the same will to it's been defending. russia's was drawing its troops gathering on the u. . the defense minister announced the move offer an inspection of drills in crimea ukraine and western countries have denounced the russian military buildup. kiev has welcomed the pullback.

he says russia still has the means to put pressure on ukraine off to the troop withdrawal of relief here in kiev tonight we've seen the markets react already here . straight think it's the euro and other currencies news of the end of that direct threat to military action by russia but i think people in ukraine have a lot of good reason to stay worried until they see hard evidence of tech and personnel being drawn away from ukraine i think people will still be exceedingly nervous there's been speculation today the russian may leave some. missile systems close to the border as a kind of open threat we've seen talk today of close gratian between russia and belarus belarus has a long border with ukraine so plenty of leaves there for russia to continue putting pressure on ukraine. next is dr phil taking a look at how electronic gadgets are affecting. the.

website. i mean. it's their story their very own personal drama. the people who survived the catastrophe. remember. and they share private footage with us that has never been seen to sit. next to turn over all sorts of people 20 minutes on d. w. .

ill need. to. see. first television screens. then conchita screens. now tablet and small phone screens. screens have inundated and changed our lives for a full decade now. on. the internet social networks games and videos devour one 3rd of our waking hours. the typical preschool child spends between 4 and 6 hours a day in front of a screen of some college. in the every country children are spending far more time with screens than the recommended allowance. there is a proliferation of alarming studies. we're finding dramatic changes in the brain

and in the behavior of these amazing so we should be concerned about this. on your runs might be in danger people ask me why did you have facebook or call because i know what it does to your brain. teenagers get addicted to. it is today screen generation really an unhealthy generation there's a lot of questions out there are screens ok how much is ok how much is too much for my child. so how do we form healthy digital habits. and what are the scientific facts. at this very moment nobody trees across the whole world are studying the impact

digital tools have on behavior the brain and medical health. this is a very young literature. let me give you a little perspective. it takes about 20 years to establish an effect in science 20 years tablets and the fact that they began to be used by very young children is more sed 7 year old or 8 years old we are doing it commercially before we have actually done the slides i would much rather we do the science 1st and then we say well is it safe or not. that alone was 1st founded by psychologists psychiatrists on pediatricians after in the field work with children.

we had a 21 isa bra just outside paris. a young mother and her daughter malia in to see dr. for the 2nd time. you're tearing up where's my princess. only hello ma'am have a seat. we'll talk this over again abets how is our little malia coming along however she now 2 years and 4 months i was a bit worried because malia didn't talk much she had certain mood changes too. much in 20 years as a pediatrician talk to your has witnessed the shop rising screens in tiny children's lives and the mounting problems all these children have interaction or disorders i have more of them than ever before temperament disorders too clearly

difficult children have always existed but there is a sharp rise of those with no concept of limits who bark at frustrations who have fits of anger or language problems poor language skills unstructured language or even none at all. bad alone no bad and by. your book you saw him unless you click with dante he's found in his own new. barely 6 months ago mario was spending up to 6 hours a day watching screens morning cartoon chinese meals in front of the t.v. you tube videos on the mobile phone after naps taking the pediatricians advice the mother stopped all of that. there's interaction now whereas before she'd often be on the you just the highly important word interactions it is key here because the screens had taken the place of interactions that needed to take place between you 2 between dad and her and between you and her that's it so clearly this altered

things it did because screens are a major issue in public health to that measure we absolutely must be aware of us. waiting for it has all the usual prevention campaign based it is but also messages to raise awareness of the dangers of screens. schools are also now wary of screens primary school teachers must cope with an increase in mindanao language disorders. today many professionals in the field of early child care suspect screens of being a cause of many of these disorders. numerous epidemiological studies conducted worldwide justify the rising concern. for and number of years people have tracked exposure to screens and young children and what they're found is that on average if there are higher amounts of screen exposure this can be

associated with negative outcomes disruption to sleep disruption to attention disruption to weight and disruption to living. scientists consider that for toddlers ages 3 and under exposure is excessive when it exceeds 2 to 3 hours per day the problem is that the digital offer is sparking growing consumption and it only ages than ever. in the 1970s most children didn't start watching t.v. before the age of 4. today screens and through their lives are just 4 months old for one 3rd of toddlers under age to exposure currently exceeds 90 minutes a day 10 times to 3 hours per day even 6 in the usa. in our digital era many children spent over a 3rd of a way to notice absorbing video content. more to the results of

this. rather surprisingly it is difficult for scientists to answer that question. the phenomenon is more complex than it appears and experiments that must be carried out to analyze it are sometimes rather odd. don't immediately christakis heads the center for child health behavior and brain development at seattle children's research institute. he's a pioneer in research on small screen. we followed thousands of children from birth to age 7 and what we found was that the more tell of a. when children watch before the age of 3 the more likely they were to have attentional problems later in life at school age. he and his team think these

programs space is what causes problems in children's brains. so the hypothesis that we had was that prolonged exposure to that rapidly sequence media would pre-condition the mind to expect high levels of input and this would lead to inattention later in life. stated otherwise a young brain regularly exposed to high levels of pictures and sounds would in the long term have problems concentrating on tusks that require time such as reading and writing. the does this in soil them bodman set off actual observed problems in children being studied. because an epidemiological studies are always subject to the criticism of the kit prove a causal relationship the next logical step normally would be to conduct an experiment what we call a randomized controlled trial in this case that would mean taking infants exposing

half of them to fast paced programming the other half to none and following them as we did in our pretty logical studies for 7 years there would be no ethical or practical way to do that and so in a sense we were at an impasse. the only work around conduct the experiment anyway but on young minds. so what we really kind of created was sort of t.v. for mice where we had the sounds corny with these lights to kind of put on a show if you will for the animals. the program the same time every day. we have lots of different parties that we layer on top of each other and then we change the frequency of the cartoon so that the mice can carry. we have

a lot of lights that surround the cages and we have them flashing the flashes coincided with the sounds that we play out about this show it you know which could do that for 6 hours per day in the monies that we're giving the stimulation to it starts in 10 days after birth and it goes for 40 days. dozens of young minds have undergone the treatment. behavior is studied from every possible angle and compare it to unexplained mice. the result the money 26 hours a day in front of the small t.v. do not behave normally what we find with a normal mouse is that they'll stay around the perimeter here they like to explore but they want to stay safe when we take those mice that underwent the sensory stimulation they have a much different pattern of behavior so they'll run around the maze like crazy and then they spend a lot of time going into the center of the maze which we would consider to be much more risky and so the way that we interpret that kind of behavior is that the mice

are impulsive. heightened impulsiveness producing cognitive problems. tests reveal learning difficulties. or memory capacity and of clues that hint at concentration problems. what we see in humans in observational studies is that exposure to rapid paced program in early life decreases attention and increases impulsivity and we find the same thing to be true in a mouse model of the current state of evidence and 20000000 team cell phones and tablets now to i think the existence. they wriggle their way into our relationships even the most fundamental ones. today screens are suspected of harming parent child relationships.

from the how little make up t. of that and the beginning of the debate centered on t.v.'s being left on constantly running in the background and the t.v. shows unsuitable for tiny viewers or cool this disrupts parent child interactions in today's world the issue is how greatly cell phone usage disrupts family relationships just how much does this device which we constantly keep by our size and which steals our attention or disrupt our interactions with loved ones. to answer this question the child an infant lab is currently monitoring 115 families in and around lynch a ping suite in. the aim is to gather precise data on families digital habits and their impact on cognitive development. studies on hundreds of infants demonstrate at the earliest cell phone screens make their ways into babies' lives the later they begin to speak even parents' constant use of cell phones may hinder

children's language development however as these studies are based solely on parents self reporting the data are not entirely reliable ok. for the 1st time linchpin university will collect precise data on baby's digital environments by placing spine microphones into baby's clothes or carry them down the list of us on the map at all analyzing us recordings shows what is actually happening but. this access to the sounds in the home lets us count the number of words pronounced by adults and by inference the number of interactions occurring today the corner on the market the stocks are we can also identify sounds emitted by digital devices dog and thought you'd. with this method research is going to tank whether families digital habits are influencing their interactions with their babies and can evaluate the consequences on their

later language development. on hardware that when infants hear very few spoken words the language learning is different as our research demonstrates so similarly the parents who are absorbed with electronic devices tend to spend less time talking to their babies therefore digital habits do have consequences follow me of the consequence. but the study on growing up in the digital world has only just begun. to confirm that the only presence of screens affects language acquisition even cognitive development we must wait until all these children under study have reached talking age. you know. the one of your programs that disrupt attention spans screen suspected of harming parent child relationships of hindering language learning. irrefutable proof is still lacking to condemn digital devices definitively but scientists have found

nothing key factor. the brains of children under the age of 2 you cannot analyze what is happening on a screen. one thing that we really need to consider is that it's very hard for children to navigate between the 2 d. in the 3 d. world it is hard for them to transfer and formation and to understand that things that are on the screen at this time out in the real world. infants difficulty with screens was revealed in experiments conducted by dr george interests at a psychology professor at vanderbilt university in tennessee. right. here is one of her experiments utla and they each take. professor chance at the stuffed toy in a room as the child watches her do things on a monitor or. the child is told to go find it in the room

which he has never seen before in real life will he locate the toys easily as if he had not watched the scene on the monitor. yet if the answer is no it's very difficult for them to learn it's more difficult then a face to face interaction and this difficulty with found is about 50 percent less learning from a screen then from a live interaction and this difference has been called the transfer deficit. before each to you and nothing if you don't a screen can be direct. he transposed to real life. to find the neurological source of this difficulty professor rachel bronstein is now investigating using cutting edge technology. her go fill in the brain right in

the middle of a deficit transfer. in this experiment a form must learn viral video chat how to position a toy robots articulated arms and legs. a very. very well i showed you. the last thing you think. yes. when the demonstration is run using a screen just like with a stuffed toy experiment most often the children fail but this time brain activity is being measured joining the exam. apparently exchange virus screen does not stimulate the brain's learning center the same way that face to face interaction does there is more activation in the frontal part of cortex when

a baby is learning from a live interaction then when they are copying from a video chat and we think that that's it's only preliminary but we think it's really exciting because it suggests that what the information that you're processing deficit and this could passionately account for this transfer deficit this difficulty in picking up information. brain st virtual action differently from real action this remains a mystery. however scientists have found a way to palliate this difficulty. when a parent accompanies a child and takes pains to put words to the action on the screen the learning hurdle diminishes but only someone. worth a quarter. ever come.

on screen action remains less stimulating for young brains than real life facts and . therefore any time a little one spend in front of screens is essentially wasted time for them. an awful month was a lot of child under 3 years little wiggy thought for so this time or to be used for developing cognitive and social skills in this way i keep the toddlers of old was let's avoid screens altogether for children under 3 just as we avoid putting steak in baby bottles clearly a baby stomach cannot digest solids its brain cannot digest screens is a clue. no

screens before age 2 or 3 and that's the official recommendation of most scientific and medical academies world lined. up to age 5 or 6 they advise a limit of one hour per day preferably accompanying the child. meal times and bedtime should be screen free. what about later that year at age 61055 with ange additional landscape becomes more complex in addition to cartoon shows there are video games cell phones social networks so what precautions indeed it would be kids. we're in a residential area of tulsa oklahoma the local max home. owners are. here as in most american homes life sentence around the

t.v. . no meals at the table even homework is done in front of the t.v. . miranda and the mother makes the meals and spends the rest of the time policing their screen you see. thank you. concerning there's enough room for everybody and this is the best meal that's the best sparkly heart. and it is there's no there's not is this what you're watching we're not changing that you know why why we're eating ok. screen time rules and limits are no big deal with trevor and anthony they know the roles and they pretty well stick to their roles and they're grateful that they are. to have screen time with the little one. the screen time is definitely a topic of arguments. johnny age 8 and charlie age 6 have grown up with

consoles and cell phones getting up off the couch is always negotiated with video game time. but i think the yards. away for an hour ok so it's $512.00 at $612.00 your time is up ok well. i can't i still like strafed a game before the time so it's just all have to wait for this to leave. ok but time starts ok. that's part of playing the game i'm sorry. it's fine you'll be fine. in the usa kids under 12 spend an average 4 hours and 14 minutes per day with screens prostates 13 the daily average climbs to 6 hours and 40 minutes watching

videos remains the main activity but we must also add time spent on social networks video games surfing the internet. in one school but teenagers spends more time in front of the t.v. and cellphone than in front of teachers. this craze with screens ranges from fortnight to achieve instagram tick-tock tweets snap chat not fix what's up amazon kindle. is any of these suitable for adolescence a critical period of brain development. is there any ready to go out. or about to leave. trinity are you ready. this morning trinity age 11 and trevor 12 have a special meeting they've been participating for a year and a half now in the lotus study ever conducted on teenage brain development are you sitting out. for every 3 months the siblings go to the tulsa brain research

institute to undergo a battery of tests. the a.b.c. study is closer 12000 children across the country in 21 centers there is. less angel a san diego salt lake city then there is st louis and then there's obviously tulsa and it's the largest of its kind. first stage in the day for traffic is to give a detailed report of a daily digital habits. time per day with the same text on a cellphone tablet computer i pod or other electronic devices or i want to time per day. social media happens just not to her facebook twitter it's going to. how often do you play mature rated video games because of the and the daughter or

sister you play video games new watch or stream movies or t.v. shows such as netflix or amazon like during summer holidays 2 hours 2 hours 30 minutes awesome. 2 practices on us are a means to identify those that might create problems for developing fundable young brains. and 2nd ticket of life you will see dramatic changes in the brain and what happens is that the brain continues to mature during that period and really. transforms from a child's brain to an adult brain the brain develops the neurons kind of move around and shift we see all of those kind of changes particularly in the areas that we think about our personality so impulse control decision making emotional regulation all of that happens really critically during this period of life.

along with travel and change it in one sense of teenagers in the study regularly get brain scan. paradoxically to prevent them from fidgeting during the exams they get to watch. the study has only just begun but it has already led to a 1st discovery the brains of children who play lots of video games have particular features. what i'm showing here are differences for kids who spend a lot of their times playing a video games rather than other types of screen media what we found in our 1st analysis is in the front of the brain or the prefrontal cortex which is responsible for emotional development decisionmaking things like that it's developed a little bit faster than their peers. we don't know if that's

a good or bad thing we don't know if video games cause that earth it just happens to be that kids who have a slightly more developed brain happen to like video games more. ringback answers on this question is the goal for a 2nd section of the a.b.c. to study. memory capacity concentration emotionalism psychological balance. the 12002 texans received individual psychological evaluations at this stage i would say. as long as you're aware of what your child is doing and as long as you don't see significant problems either at school at home with peers i would not worry about it we don't really have good evidence at this point that there are significant problems if you notice that there are problems because the kid has problems at school maybe is so it feels particularly anxious why has temper trant

10 drums that's when i would look at it more closely. the 80 cd studies broad conclusions will be reached by the time trevor and trinity are young adults in other words not before 2027. there is nevertheless one issue that these scientists need to address promptly and it is on the minds of parents in every nation with this level of consumption is the new generation slipping into screen addiction. produces behind screens strange hypnotic power. the. professor offered to read of california state university in philly to analyze how brains apprehend social networks. and he's feeling these helping

patients are optimized to confiscate users time and detention. in face to face almost daily interactions we get several dozen sophie awards for the bulk of social media we have the same thing on a much larger scale as opposed to getting a few taps on the shoulder a few nice words being said to us we have. andras sometimes thousands of friends that communicate with us and provide us which we ward such as likes such as commenting on our posts such as repose thing our opinions and so on and that makes us really feel good. thanks to brain imaging professor to ram has even identified the mechanism this essential need to x. deploying to hijack our new rounds as with most addictive behaviors the robot would say he's a.
