berlin. a call for urgent action to end global warming as the un's global climate summit opens in germany. after a colorful opening, delegates got to work to take the paris climate agreement to the next stage. their goal, to prevent the global temperature from climbing more than 1.5 degrees celsius. u.s. president donald trump tells north korea its aggressive behavior is a threat to the civilized world. but he is still open to talks with north korea's leader, kim jong-un. and, huge leak of documents show how corporations and the superrich invest in tax havens.

we will find out who has been implicated in the so-called paradise papers. ♪ >> i am brent goff, it is good to have you with us. we begin with the weather and the climate and what to do about make them both if not better, at least not worse. the u.n.'s latest climate summit has begun in the german city of bahn. representatives from over 190 countries will spend 10 days discussing how to tackle climate change. the conference opened with a traditional fijian welcome sarah to -- welcome ceremony. fiji is chairing this conference, as one of the countries suffering the worst from climate change. they said failure is not an option, particularly for fiji.

delegates are working at this conference to find ways to cap the expected global temperature increases at 1.5 degrees celsius, or less. >> we must not fail our people. that means using the next two weeks and the year ahead to do everything we can to make the paris agreement work, and to advance ambition and support for change before 2020. to make our commitments in full, not back away from them. and to commit ourselves to the most ambitious target of the paris agreement, the cap of the global average temperature at 1.5 degrees celsius, over that of the preindustrial age. brent: we want to pull in louise osborne. she is our environmental issues it -- editor. she joins us from the german city of bonn.

good evening to you. people watching us will think, you had the paris climate agreement two years ago. so why do need this conference in bonn now? louise: the paris agreement was very important and brought together the international community for the first time. but now it is about hammering out the nuts and bolts of how exactly they are going to implement climate action plans they are putting in place at the moment. if you think the paris agreement like a smart phone, and the rulebook they're working on to make sure they implement these issues, is going to be the operating system, it will not work without an operating system. that is what this conference is really about, making sure they can make the paris agreement work. brent: that is a great analogy. with a couple of updates to keep it running smoothly, as well.

it seems if you look at the latest data, we are on track to see a three degree temperature rise. that is based on the latest model for the entire planet. is that adding urgency to these talks? louise: that is right. if they stick with the climate action plans countries have already put in place, that will be a three degree rise. that is what has been projected. it is adding urgency to the talks because they realize they have to have more ambition. they really have to make sure they can keep below that two degree limit, 1.5 degrees, if they can. with fiji as the president of the conference, they are feeling the impact more than anyone else. with them taking charge it is about trying to make sure they can keep those targets in place. brent: even if the world manages to limit warming to 1.5 degrees or two degrees celsius, how much

risk will remain for these pacific islands like fiji? louise: fiji is already experiencing some of the problems when it comes to climate change, increased flooding. the islands nations are going to feel this, to some extent. even with the 1.5 to two degrees rise. it is about limiting the damage that is already being caused. it is not just about the island nations. we have also seen extreme weather events all over the world, and also increased forest fires, all linked in some way to climate change. it is really something they need to work on. brent: louise osborne, joining us tonight from the german city of bonn, helping us to put this latest u.n. climate change summit into perspective. thank you. louise: thank you.

brent: tonight, police say the man suspected of killing 26 people inside the texas church had been in a domestic dispute before committing the massacre. devin patrick kelley died of a self-inflicted gun wound after fleeing the scene. kelley's in-laws reportedly attended the church in sutherland springs, texas. the shooting is the deadliest mass shooting in the history of texas. >> the pastor at the first baptist church always stop to bring people together. -- sought to bring people together. >> give them a hug, let them know it is good to see them in god's house today. >> this video from last month captures a service like any other. it was faith, family and friends. until this sunday, when a gunman came, intent on killing. among the many victims -- >> we had a long night, with our

children and grandbabies that we have left. reporter: the pastor's 14-year-old daughter. >> it was not comprised of parishioners, we were a very close family. we ate together, we laughed together, we cried together, and we worshiped together. now most of our church family is gone. our building is probably beyond repair. and the few of us that are left behind lost tragically yesterday. reporter: the suspect is devin patrick kelley, 26-year-old with a history of violence. he was discharged from the u.s. air force for beating his family. he was chased out of town by residents before turning the gun on himself. amid the hatred of this tragedy are tales of heroism. >> i saw the firefight between the shooter of the church and the neighbor, a resident here in town.

after the firefight, the shooter took off and the neighbor came over, jumped in my truck and shot of -- and said, he shot at the church. we have to get them. let's go. that is what we did. reporter: they say the gunman could have been targeting his in-laws. >> there was a domestic situation going on within this family. the suspect mother-in-law attended this church. we know he had made -- she had received threatening text from him. reporter: almost 1/10 of the population of this town was killed on sunday. in sutherland springs, they are holding each other a little bit closer. brent: here are some of the other stories making headlines around the world. zimbabwe's president has fired his vice president. he had been a main contender in

the race to replace mugabe. his wife grace could succeed him as president. he said he had been dismissed for not being loyal, respectful or reliable. liberia's supreme court has postponed a runoff election tuesday to allow the commission to investigate fraud in the first round. a soccer star and vice president placed first and second in the vote, but neither garnered enough votes to win outright. vietnam has been hit by heavy flooding after a powerful typhoon killed at least 44 people and led -- left more than 100 missing. more than 100,000 homes have been destroyed or damaged. $10 trillion stuffed away in offshore accounts. governments around the world are scrambling to investigate.

the european union now says the paradise papers have placed a renewed emphasis on fighting tax avoidance. they could press for both plans to create a blacklist of tax havens among the millions of documents, evidence some of the worlds richest individuals and businesses are doing what they can -- you guessed it, to hide their cash from the tax man. reporter: the queen of england is there, the rockstar, bono. american firms apple, facebook and nike, also part of it. the massive paradise papers leak is a snapshot of massive tax dodging, most out of bermuda. big names and big companies caught once more in a controversy over their finances. that is boosting those who want to end tax dodging. in the u k, jeremy corbyn suggested the queen should apologize after the leaks showed her state made offshore investments. >> we have to challenge the culture that there is something clever about avoiding taxation.

taxation is what gives us ambulances, fire tenders, safety in our lives. we have a responsibility to pay for. reporter: others agree to the regulations with a shrug. russian officials point to the legality. wilbur ross said there was nothing improper about his investments in a firm connected to the russian state. donald trump could even use the leaks to support his plan to slash corporate taxes. governments like the u.k. and germany have been trying to close loopholes. the e.u. said just a collective response. but even this could face challenges. >> we are blocked by the fact that member states can -- consider they should be careful. now we are in a different period, a transparency evolution. it is high time everyone goes in the same direction to eliminate fraud and combat tax evasion.

reporter: when it comes down to clamping down on tax dodging, the shame game might be the most effective option. brent: in belgium, the ousted catalan leader carlos pushed among -- puigdemont and other leaders have been released, but they must stay in the country. they had turned themselves into the police, following possible extradition. they have filed charges against them in the referendum -- independence referendum, which the spanish government says was illegal. u.s. president donald trump has warned north korea, what he calls the era of strategic patience is over. speaking in japan on his tour of asia, trump pushed his host, japan, to buy more american military equipment to protect itself against north korea attacks. trump said he would be open to

talks with the north korean leader, kim jong-un. reporter: going for the gut, president trump's hawkish stance on north korea got personal when he met with japanese families of those abducted by the nuclear arms regime. he is not the first president to do so. but with -- it added emotional fire to his talk. emphasizing the u.s. and japan long-standing relationship. he called north korea's ballistic missile launches over japan outrageous. pres. trump: the era of strategic patience is over. some people said my rhetoric is very strong. but look what has happened this -- with very weak rhetoric over the last 25 years. look where we are right now. reporter: prime minister shinzo abe says his government stands together on the issue, agreeing with trump that all options are

on the table. >> no one wants a conflict. neither myself or president trump. but north korea continues to challenge the international order and repeating provocation. the international community needs to apply pressure to north korea. reporter: the prospect of armed conflict took on an economic dimension during the visit. trump called for free and equal access for american exports to japan's market. his answer to north korean missiles is, japan buying more defense hardware from the united states. pres. trump: [indiscernible] when he completes the purchase of military clement from the u.s., he will easily shoot them out of the sky. reporter: from japan, trump heads to south korea, which has long been in north korea's crosshairs. brent: you are up-to-date with "dw news." we are always here in berlin.

i am brent goff. we will see you again at the top of the hour. [captioning performed by the national captioning institute, which is responsible for its caption content and accuracy. visit ncicap.org]

>> i just wanted to get back online. >> eric always wants to be online, he is an internet addict. the 20 world spins lots of time on computer games and social networks. he realized that himself, and now wants to end his addiction. but he knows that to do that, he will need help. erik is on his way to his computer.

>> here is the monitor. that is the equipment for the computer. here is the keyboard. here is a drawing tablet. the monitor is here. here is all the stuff, mouse cables, webcam, all the extra stuff. >> how do you cope with all this being here? >> to be honest, the moment i'm brought it all into the seller -- cellar, it was if a tremendous weight fell from my strollers. sometimes i miss it and would like to get back online. but on the whole, it feels good. >> maybe he is painting too rosy a picture. even if his own pc is out of range, eric easily find ways to

surf the internet elsewhere. and then there is always his smartphone. >> i use it only when i urgently needed, so it is usually here. but that is a danger, how do you define urgent? >> how often do you urgently needed? >> if i urgently need it, maybe once a week. but i use it every few days. that is the crux of the problem. >> how do you find it? >> not so good. >> eric is moving from the digital to the analog world, from a drawing tablet to paper and pencil. he draws comics. the main thing, do not think about video games. when his computer was still on his desk, eric was often online, day and night. he lives alone, with no one to interrupt him. >> my record was 20 hours without a break.

ok, to go to the toilet or prepare food, but i ate in front of the computer. i started in the morning and continued until late in the night. actually, until the next morning. >> but in that situation you thought that was ok? otherwise you would not have done it, right? >> no, i had already started to ask myself if it was ok. then i realize, what i am doing here will turn out badly. i have to change something, but i do not have the strength to get out of this by myself. the shock is off. that was the point where i realized, i have to get help or i will go down the drain. >> eric thought help -- sought help at a clinic for online addicts.

usually all the seats here are occupied. but the other internet junkies did not want to appear on camera. >> at home i had a lot of stress with my mother and night moved out early, just 15. at school he used to tease me and bug me, it was horrible for me. when i came home, there was the pc. i played, it was a way of escaping. all the unpleasant feelings were suppressed and a gradually turned into a habit. >> that means it has a positive effect for you at that time. you just felt bad -- better because of it. >> i always looked forward to it. in the morning i thought, ugh, have to go to school. at school i thought, just a few more hours and i can go home and play. that kept me going. >> these days, eric has lots of

time. he quit school and broke off his volunteer year working for ecology just to keep playing, even though he now looks for ways to distract himself from his craving for the internet, eric is far from clean. he still visits his buddies just a check is emails. -- his emails. >> this is benny, they have known each other for years. benny is a big fan of video games, which gets eric gushing again, too. >> imagine a market place like ebay or amazon. you can buy games on your steam account. you no longer have them physically on a cd, they are stored online in the library. and you can access them from any

computer, not just from home. if you have a computer elsewhere, you can install games from your account. that makes a more practical. over the years, i have amassed quite a collection of games to read there must be 40 of them. i am sure i must've put 200 or 300 euros into the games. >> it is not just the addiction itself. it is also the expense, which can ruin you. hear an update, there, a new game. it piles up. >> i estimate i spent about 1000 euros, or maybe more. >> every add-on costs another 50 euros and they come out every year. [indiscernible] with that money, you could get a

drivers license. >> sure must be a good computer game. >> but it is not just a computer games, he spends a lot of time on social media and digital portals. >> youtube is one of my weaknesses, definitely. you can watch it anywhere, in the library, internet cafe with friends. it is terrible. >> you asked me not to send anymore. >> you click on a video and you see 10 more suggestions and you click on the next. soon, you have lost two hours. >> eric is in therapy, what do you think about that? >> really, you never told me. >> i am. >> it is definitely a good idea. to be honest, you told me you wanted to stop using a pc altogether. that makes no sense. you have to see the difference between leisure and work. when you want to apply for a job, you have to sit in front of

a computer to write your application. you can submit one that is written by hand, like my grandmother did, in the 1950's. >> but eric still disagrees with benny, and the tendency of the times. when he draws his comics, he manages to distract a few boys away from their smartphones. >> it is a bit of a dinosaur, but i am happy with it. >> what you think about everyone else, especially young people, walking around with a smartphone? >> i got rid of mine a year ago and i have never regretted it.

it is overwhelming how things are today. everyone has one. i am really glad i am not five years younger, but the temptation would be greater. you cannot escape it anymore. >> eric wants to withdraw from his addiction. he is serious about therapy and goes to an addiction clinic. stationary treatment, group therapy, individual talks. cameras are not allowed. he is released, two and a half months later. >> how was it? >> it was great. i also -- i already miss my fellow patients. i drew this and occupational therapy. it shows the contrast between the mask i showed other people, and my inner life, which i try to hide.

i had to delve into the difference. since i have started doing this, i have the feeling i do not need my pc anymore. but of course, it is not easy. you have to learn to be -- i have to learn to be more honest with myself. but i want to. i have realized i feel better when i own up to myself. sometimes it was very intense, i cried. i had not done that in a long time. >> and why? >> one evening it was all too much for me. everything i had repressed for so long, the reasons i played online, it surfaced again. i could not go back to that again. but at this moment it was all so much.

and it all came out. it still feels funny, i feel naked in comparison with before. but i no longer feel this inner pressure, i do not feel as if i need this distraction, this desperate need. >> eric has accomplished a lot and exposed his innermost self. but he knows he has to continue working on himself. so what is your plan now? >> i want to get to know myself better, so i'm going to go to a buddhist monastery for two weeks. i am looking forward to it. then i will see, i would like to study social work and i have to see whether i resume my volunteer work and find another way of finishing vocational high school. that is my idea for now. >> and the computer will stay in the seller? >> not completely. i decided to distribute its parts. my best friend gets the monitor, another friend gets the drawing tablet. i am going to give it all away.

>> ok, good luck. >> thank you.
