the prize winning documentary from the forest starts this month on d. w. . this is deja vu news live from berlin drought and wildfires across the globe what's causing the extreme weather conditions. this view from space shows parched regions that are normally of very lush green lawsuit climatologist what the future may hold for planet earth also coming up a special report on migrants desperate to get into the united states they take huge

risks even though they have little chance of getting into the gutter. if it be anywhere must people get on that train but not quite the train. at about fifty miles per hour one step that can mean the difference many in me and dying. i'm brian thomas thanks so much for joining us temperature records are being smashed across the globe while fires are raging in portugal spain and the united states and there's a drought right now a severe one in australia and other countries as well so what's behind this unusually hot weather in a moment i'll be talking to a climatologist but first we have this report on the high temperatures that some experts fear could irreversibly disrupt earth's ecosystems. central europe from

space too hot and too dry this is commander of the international space station alexander guest just had a chance to take my first photos of dried out central europe in germany since a few weeks and was shocked what should have been green is now brown never seen it like this before farmers across the continent are worried about crops the french version mountains a simply too dry about half of this farmers corn crop has already died. and rivers are also drawing up this is in brandenburg in northern germany shocking scenes like this are likely to become the new normal according to an international research team's latest study the name for this new normal hothouse earth i said it is when the earth when the climate is much warmer than it is today three to four degrees warmer than it already is four to five degrees warmer than in the pre-industrial climate yankee. climate targets aim to limit the earth's warming to two degrees celsius but scientists now think that that is even too high setting in motion

processes that have both more extreme and irreversible such as glacial melting once they're gone the sun's heat stops getting reflected and starts getting absorbed speeding up global warming the potsdam institute which specializes in climate research argues that without putting in place pacific human made climate protections the seas could rise by up to sixty metres. and that's you know this is something long term but of course in the next few decades and by the end of the century these effects will have significantly negative impact on cities which are often on the coastlines. climate scientists say we need to drastically cut industrial greenhouse gas emissions traveling less by plane or by car and eating less meat as well. in the short term however both humans and animals are finding more immediate ways to cool down. in the united states these record temperatures

are fueling the worst wildfires in the state of california history the mendocino complex fire has now killed eleven people and scorched an area the size of los angeles some ten thousand firefighters are battling the blazes in the northern part of california the flames have destroyed hundreds of homes since igniting over two weeks ago the mendocino fire is one of over eighteen blazers raging across california. so are we entering the era of hot house or earth to talk about that now i'm joined by clarifies and she's a researcher from climate analytics an organization that supports what they call science based on a policy to prevent dangerous climate change welcome to the show it has been a savage summer here in europe elsewhere as well australia the united states what's behind this extreme heat wave well if you need to persuading that climate change is going to enter into so that it is already in for thing and joining us all

then i think this heat wave provides an excellent example as you said it's had across the great globe in particular of the northern hemisphere we've seen high temperatures in forest fires in greece and portugal and it's not just the high temperatures that are an issue it's also a lack of rain so germany have seen better percent less maint than it would have done in the same century so it's really a double whammy for people on the farm and now it's not rocket science that such high temperatures are linked to climate change or woman climate will lead to higher temperatures there's also an impact from climate change on atmospherics that creation so in the northern hemisphere the jet stream is influenced by the temperature gradient across the world and changes in this jet streams activity can lead to prolonged climate events such as this heat wave and drought and twenty thousand is an excellent example of. so you mention this double whammy i think that's a good way to describe it and our report cited earlier this international study

that a hot house period is upon us if you see us headed into are we headed into a protracted period of drought and extreme temperatures so we're not yet in this hot house harriet we still have time to prevent that and really what this study is doing it's a call to arms to say let's get to the paris agreement temperature limit of one point five degrees which keeps us out of the risk of shifting into a hothouse type climate as it stands the policies that we put in place take us to about three and a half degrees of warming and that's also something that we do not want to get near me we need to stay below well below two degrees keep it to one point five ok the scientists writing about harthouse urse the trend there said quote that this trend would be propelled by strong bio geophysical feedbacks difficult to influence by human action does that mean we could reach a trigger point where if not enough is done and temperatures continue increasing

that there's no way back. and the scientists the talking about tipping points in the climate system which a very complex parts of the climate system such as ice sheets the rain forest oceans that you lation and it's thought that if these reach a certain if he reaches out in temperature level we could see very rapid and some sometimes there of us the bull changes in these systems now we're not yet at the temperature where that would happen we cannot really pinpoint a number where the risk of these events happening lies and the science is not ready to do that but what the science can tell us is that if we limit temperature wise to one point five degrees we stay out of very high risk zone if you would as a research show briefly if you could are we going to stay within that one point five degree range were is that as dangerous as this new international study showing there are seventy ways to keep below the one point five degree limit. experts have shown them up multiple different pathways through which we can keep our missions

down we need to act rapidly though so we need to reduce our emissions by about half in the next decade in order to keep to that one point five degrees limit but yes it certainly possible clarifies and from climate analytics thanks so much for being with us this morning thank you. now for a look at some of the other stories making news around the world today in the nation officials say the death toll from sunday's massive earthquake in lombok province has risen to one hundred thirty one aid workers are struggling to reach victims in remote areas many are still believed to be buried beneath the rubble some one hundred fifty thousand people have been displaced by that quick. the former malaysian prime minister najib razak has faced court over corruption charges he pleaded not guilty to three counts of money laundering charges relate to the disappearance of more than ten million dollars from estate investment fund prosecutors reopened investigations into the missing money after knowledge of lost elections in may. the conservative politician even duke

a has been sworn in as colombia's new president in his inauguration address he promised to heal the nation's divisions but thousands gathered to protest his presidency there against his plans to rewrite the country's peace deal with leftist ropes. saying in the region nine guatemalan children separated from their parents at the u.s. mexican border have been flown home and reunited with their deported families now they were repatriated under president trumps zero tolerance immigration policy despite the high risk of being deported many migrants continue to make this dangerous journey in our next report we follow one hundred woman and her child done just that. miriam and karen don't have much luggage they have little apart from their children they don't know what to expect but are well aware of all the possible perils. so much and. i'm putting her in

danger in so many ways her health her life. so much could happen on a journey. she could be raped or something could happen to her. you know where. i'm risking a lot. not only my life but has to be part of. this this is the first hot meal that merriman phyla to be eaten since they left honduras marion decided to escape after injuring her partner's abuse for too long she spent the little money they had as they were crossing guatemala. many more. we escaped from having the what if he'd known he would never have let us go. he'd have done everything to stop us. but it was unbearable. that one of the violence was having a clear impact on the little one. and also i mean look at them but that's why i am

risking everything now that the yes i thought it. was someone else that is. said miriam also has an eight year old son whom she left behind. she doesn't know whether she'll ever see him again. b.c. . what is going. it's very difficult to make such decisions you know what no woman deserves to go through got it about. put up another study on i have to be strong and fight for a better future for both my children. even if it hurts to walk is that why it's hard but i have to fight but aussie they are going to check. the fight for a better future is what motivates hundreds of thousands to embark on this perilous journey through central america every year they have dreams of

a better life in the u.s. a life without violence a life with work. trying to get on freight trains in mexico then they travel thousands of kilometers. to collect money in order to buy a warm breakfast before the train arrives if they manage to get on they'll have to survive without food miriam is worried that she might be separated from violet at the u.s. border like sounds of other parents and children. she thinks u.s. president donald trump is unfair. our children are very precious to us and then someone comes and says only because he was in his country. but he's going to separate me from my daughter. and he has no right. to.

finally the train arrives. this is the area where people get on the train in quite a while because the train that i don't doubt fifteen mph one step aside can mean the difference between living and dying. now miriam will hand over her daughter temporarily. miriam manages to get on the train and so. with violet. they will soon disappear from view bound for the u.s. full of fears and hopes at the same time.

we have some sports now and in tennis to multiple grand slam winner showed signs of their best war but masters stand go overcame the curios three sets meanwhile the reigning wimbledon champion over talk about how the slightly easier path into the sack. stand in orange must have been fearing the worst against nick at full steam the australian it's hard to keep up with. the curiosities form can change dramatically from one set to another in a second battering the initiative aided by an injury to his heavily strapped opponent. fabric who will know how bat fails his ranking has slumped after two knee operations last year. but he's getting back to his best the majestic backhand flowing again this way swept through in three sets. novak djokovic is another veteran big name who's had his share of injury problems
