the behavior is only served to remember the. surgery you durrance. d.w. . business daily news line from berlin tensions run high in the u.s. state of minnesota after and another black man that's shot dead by police the officer who fired apparently in the still current gun taser a nighttime curfew has failed to keep a lid on protests as president joe biden asks for restraint also coming up. world

leaders condemn a build up of russian troops along the border with ukraine it's feared a 7 year conflict between the 2 nations could flare up again. and finally it's back to the pot england says she hears to the easing of cope with 19 restrictions as the heart of lockdown and a mass vaccination drive begin to pay off. some of it to have you with us protesters and the u.s. state of minnesota have taken to the streets for a 2nd night after a young black man was shot dead by police near minneapolis the officer who fired the acts 20 year old dante a right apparently confused her gun with her taser tensions and minneapolis were already running high before this latest incident

a white former police officer is currently on trial here charged with the murder of george floyd president joe biden has appealed for peace. the last moments of don't have rights life because by the body cam of the police officer who fatally shot him. 20 year old wright isn't restitching a traffic stop. he struggles free and gets back in the car then 7. police say the footage shows that the officer used her gun by mistake. as i watch the video and listen to the officers commands is my belief that the officer had the intention to deploy their taser but instead shot mr wright with a single bullet this appears to me from what i viewed in the officer's reaction in distress immediately after that this was an accidental discharge there resulted in

the tragic death of mr wright. angus spilled out onto the streets hours after wright's killing. a dusk to dawn curfew was imposed to stop further on rest that protesters gathered for a 2nd night in the suburbs of minneapolis outraged by yet another death of a black man at the hands of a police officer. like. president joe biden appealed for calm. we do know that the. trauma is just the walk. through serious consequences but it does not justify violence. but the shooting of don't want to draw it because fuel tensions in this city already own a very nothing notorious case not far from where wright was shot dead it should

have been deal for george floyd is on trial for murder. let's not take a look at some other stories making headlines around the world one person has been killed and a policeman wounded and the shooting at a high school in knoxville tennessee gunfire was exchanged when officers approached a male suspect hiding in a bathroom 3 other students at the same school have died in gun related incidents this year. the japanese government has given the go ahead to a controversial plan to release massive amounts of radioactive water into the sea the water has been stored and tanks at the fukushima nuclear plant since the 20 a level earthquake and tsunami wrecked the plant the operation will begin in 2 years. israeli prime minister benjamin netanyahu has insisted that iran will never be allowed to develop nuclear weapons tehran has blamed israel for

causing a power failure and its biggest nuclear facility media reports have also linked the incident to an israeli cyber attack well leaders are trying to revive a stalled international deal limiting arounds nuclear program. russian prison officials have threatened to begin force feeding jails opposition leader alex a no ball me that's according to nevada his legal team the kremlin critic has been on a hunger strike since late march he's protesting what he says is a lack of proper medical treatment at his prison facility east of moscow. a group. well leaders have condemned russia's most recent military activity in and around here craig the g 7 group of advanced nations says it's deeply concerned by what it calls russian provocations ukraine accuses moscow of sending thousands of troops to its border and the crimean peninsula russia says the soldiers are on its own

territory their affair is the unresolved 7 year conflict between the 2 sides could flare up again. a russian military camp set up suddenly close to russia's border with ukraine witnesses have reported seeing rows of tanks in the area and artillery being moved by train and leaders in europe and the us are trying to find out what. russia is not denying the troop movements but says it's not threatening anyone. in spite of the words of receiving the questions are being asked what is it that the russian federation is doing on the border with ukraine got the answer is very simple we live there it is our country some kremlin figures have gone further setting out conditions for a possible russian intervention against its neighbor which is beginning of military actions is the beginning of the end of ukraine. the build up seems to be russia's

biggest along the ukrainian border in 7 years. but that was when fighting between pro russian separatists and ukrainian troops 1st erupted in ukraine's east more than 14000 people have since died in that conflict which has yet to be resolved. ukraine's president volo dimmers alinsky recently visited frontline troops he's called on nato to put his country on a pathway to join the military bloc something moscow has called an acceptable. meanwhile washington is sending warships to the region and says it's closely watching the situation well 1st let me say we are concerned as i've said in the past but we've been of course watching it over the course of the weekend about the increasing aggression of russian forces on the border secretary blinken and

secretary austin are in brussels this week meeting with their nato partners and we will of course i'm sure this will be a topic of discussion the coming week could well decide whether the tensions in ukraine escalate further into the biden administration's 1st international crisis germany center right coalition is still looking for a candidate to send into the race to take over from chancellor angela merkel after 16 years in office she will be stepping down after september as election michael c.d.u. party is backing its own leader on the lashes but locke was there the leader of the bavarian sister party c.s.u. is also going to get a shot at the top job. this is marcus the race to be the next conservative candidate to run for a german chancellor is turning into an old fashioned power struggle on sunday the 2 men agreed the decision should come soon and to respect to whoever is chosen. but

less than a day later battle lines seem to have been drawn on monday morning at the recently elected c.d.u. leader held meetings with his party's executive and not really a surprise they backed him to be the candid it the man himself sounded impatient to get out on the campaign trail. and. everyone wants a decision seeing all the facts are on the table the problems we need to solve are so big that we should no longer be preoccupied with our internal party issues but rather with the major tasks that lie ahead for germany today tomorrow this week and in the coming months morgan in the next new not legal but by monday afternoon markus zusak head of the smaller bavarian c.s.u. had the backing of his party leadership he thinks the conservatives should ponder the candidate question a bit longer not only is he personally more popular than lash out he also claims to

stand for a style of politics that people want. the conservatives have never fallen out of favor with voters so quickly before holds on to everything but there are a clear indication of what the public is thinking and we can't cut ourselves off from the majority of people. that mention and some that ford certainly needs now is public support from the white or conservative parties perhaps from members of parliament worried about losing their jobs if the wrong man leads them into the national election in september if those voices did not materialize it seems very likely christian democrat will be the choice to seize the baton when angle america leads the chancellor later this year. people in england have been enjoying some new freedoms thanks to a loosening of coronavirus restrictions drinkers can now once again enjoy sipping

a beer and a pub garden and many non-essential shops and gems have reopen the government hopes it's the 1st step back on the road back to normality made possible by lengthy stay at home orders and the u.k.'s fast vaccine rollout what's helped bring down infections and deaths. despite the unseasonably chilly weather there was an arab spring across the u.k. as many businesses reopened for the 1st time since january. long lines of eager shoppers formed outside clothing stores in london some brits got their 1st real haircut of the year. but for others this is what they've been waiting all winter for a pint of beer with their friends. british people i mean the way we cope with the british just going to the pub as often as possible so we can do nothing for months and now when i look at that we're back to normal but we're not but it's no way so it's not right it's all very strange all my tense point already. i'm speaking

straight is great going out and working out in the high street and seeing everyone smiling every day for those like you with positivity and hope that we can make out of this it wasn't just patrons celebrating the reopening of 4 now the outdoor seating at pubs the owners are optimistic that they've made it through the worst of the pandemic. but we have survived through some of the toughest that have been improved in europe now you know what you need now do is that's only 40 percent of all you have space that they can attend right now because it's best where the forests either here in the united kingdom. but we really need to see defoe the removal of restrictions before we can really get to trading have rules that mean those businesses throughout this. health authorities are warning the british to

remain cautious another wave of the pandemic is not impossible but if all goes according to plan the government could lift all restrictions by the end of june. and soccer now by in munich are preparing for a champions league quarter final clash with paris sharma the move very desperately need a wind to keep them in the competition they won last year but pay is safe impressive display in munich last week shows byron are facing a tough challenge by in a really custer's underdogs but that's how they see themselves as they had to paris in need of at least 2 goals to qualify for the champions league semifinals after p.s.g. smushing to grab 3 to win in munich is this the top of gaba more before it's a tough task but we are all looking forward to it for this i think games like these are why you play football and why you're here to buy a munich we want to try to cause a mini upset and powerless of us who more or impose money can. buy and chances of

upsetting the odds looks slim there with the key players chief among the injured robert leave and. his team mates will miss the pollutant pull who has rattled in an incredible 42 goals in 36 much is this season. one ray of hope for byron has been p.s. g.'s in different home form the parisians latest disappointment was a one nil loss to leo in the league as i look at them. it's something that we all have to look at again at the end of the season. but let's hope that performances start to turn around against. vengeance for last season's painful defeats in the final should be motivation enough for the argentines players to find their feet again on home turf. and before we go i want to take you to brazil because kind surface in rio de janeiro have been enjoying perfect conditions hundreds have been speeding across the water against the spectacular backdrop of the sugarloaf

mountain but that is famous beaches are closed for general use because of coronavirus restrictions but individuals or its activities are permit the kind surfers say that when conditions are this good it's have to get out there to riot the way and and way. maybe to get away for a moment for everything happening on land here watching through w. news of the gulf really for me and the entire team here in berlin thank you so much for a company. that . you feel worried about the. truth. on the other people on the green fence post and to me it's clear remains true. join me for a deep dive into the green transformation for me to use the council.

the commenters training on to view the facts of climate change many researchers believe we have to intervene to prevent must from happening we saw so many people it might sound a bit like playing on. manipulating oceans seeding tolerance. creating a sunshade for the os to solve these are just some of the ideas. you can't tackle something this scale this moving this fast. just science modifying our climate is it hubris in iceland researchers have already turned greenhouse gases into stone on then you can see sort of bright spots and that's what this is to do we inject it into the pilot reservoir that's the solution

to a definitely in my opinion this would be one of the solutions that light a large scale scientists want to interfere with the arts processors plan. a layer can geo engineering save us not just by getting harmful c o 2 out of the atmosphere but also by cooling our planet. we're on our way to meet some researchers pursuing radical i.d.s. . i'm worried that climate change has become a kind of political abstraction evil has lost track of the drive to protect their part but they lots. of harvard university has one of the most controversial climate researchers in believes it's high time we had an emergency plan is idea is to create a sort of screen using dust particles which would reflect the sun's rays weakening

or even holding global warming here 1st big pilot project names copecks keeps being postponed and there's still not too much opposition. but it is is it something that might be a combination with emissions cuts reduced overall climate risk maybe substantially that's the evidence we have for climate calls so the question is to what extent the solar charger reduce climate rest actually harm people of iraq like extreme storms extreme temperature sea level rise. those are research questions that we don't know the answer to. so course sona radiation management is a gamble little research has been dominant the risks and yet it could be our last line find when it comes to terms being global warming. in practice it would mean at least 10000 aircraft injecting distances for every 2 years the planes would release

sounds for particles as evenly as possible a town to dudes of molten 10 kilometers these particles would reflect one or 2 percent of the incoming songlines. the fact that danced in the stratosphere cools the planet has been shown by powerful volcanic eruptions such as pinatubo in the philippines in 1991 at that time but lobel temperature dropped by normal point 4 degrees. so much and you have to put in there well it depends how much solar we want so there's no right answer to that but you know the quantity we measured it something like a 1000000 tonnes a year which is that of a well it's a lot of not a lot. it's we're putting billions of tons a year of c o 2 in the atmosphere so one of the ways to think about it is there's a $1000000.00 to $1.00 ratio between the amount of warming power of c o 2 in the atmosphere and the amount of kind of cooling power of say something like

acid or some other material in the stratosphere so a 1000000 times it's not technologically a lot it's doesn't cost a lot but it's a real direct perturbation to the environment doesn't that tell us also that the stratosphere is just a place you should not interfere because it's so sensitive you're speaking as if the alternative is now on interference but the c o 2 is already in the atmosphere even if we cut emissions to 0 tomorrow just basically impossible but even if we cut emissions very quickly which we could do that doesn't make the client all go away and humanity is a long way from 0 emission. once we started pouring some far into the stratosphere for some shade would have to be replaced regularly otherwise temperatures could rise to levels even higher than they would be without the many people nation. the technology skeptics. my biggest fear is that

climate change will advance to the point where this planet who no longer sustain human life. to various true jerry fears that so no geo engineering will change weather and precipitation patterns damage the ozone layer and produce more acid rain some studies show some interest for dru geo engineering is watch them climate change itself and even researching the matter and seas dangerous governments are watching this closely well companies are watching this closely the military is watching this closely. so there's a political experiment that's happening that says you know what what if we could go this route and you're opening up a pathway and the further you go down that pathway and the more you make it seem real so so an experiment is is is a is is research but it's also political theater you have that you will never stop people from thinking and from searching for ideas and solutions the idea of to engineer is already in the world so you can't stuff that. you can't stop the idea

of doing it in erring from existing but but what you can stop is it being considered a good idea many people including me have talked about how an equal solar geoengineering is how it would help one place and hurt another but actually in climate models when we put it even amount of solar geoengineering in it seems like really every major region in the world has their climate risk for the east german nation with this leads to a planetary wide experiment you have one planet and you're risking the whole planet to do that experiment for sure solar has risks but not doing so or jewish or and also has risks. while wearing creasing a aware of the a facts of climate change we can't accurately predict the consequences of geo engineering. we're on our way to visit an environmental activist who's committed to strengthening nature's own capacity herself. to know what my biggest fear is.

is that the history of the collapse of civilization. is really repetitive. and we're seeing the tail end. of. the most expansive. civilizations. human history. in remote south america chris tomkins and her husband doug have given vast areas of land back to nature together with the governments of chile and argentina they created 13 national parks an area the size of sorts among. the 1st ones patagonia park since the death of her husband chris tompkins lives here alone. she's told us to come right on into the house and to please take our shoes off. at. the.

split the end of the world yet christine tomkins was head of the outdoor clothing company patagonia husband had founded the brands as 3 and a north face yet in the 1990 s. they left the business wound and went on to invest around $350000000.00 in nature conservation. i don't believe that technology is some sort of techno fix that will fix all the technology that got us here in the 1st place look if i thought that was even remotely possible in the short term i would say great and then i really do say well then why are you showing up so late because the party started a long time ago there's no way to turn it better there are no messiahs when it comes to this you can't tackle something of this scale this go moving this fast

with just science it would wilson said we should give i think have heard it. in this size and scale you do it can there make an ecological difference you can enter these places and you understand what is was could be. and that's an enormous enormous contribution. i have begun to see the value in things or major the value of things more by their absence. chris tomkins amends the destruction and inequality in the wild in her mind entire regions should be protected from humans and especially from the clutches of a globalised economy you. cannot save us from climate catastrophe probably

not but maybe there's more to it than that it's about spacers where natural systems can regenerate where we can save the things that represent life on this planet. we believe that all life has intrinsic value the 9 human world is struggling and much of the human world is struggling so we see the health of all life on the planet guy in their own direction and have done for the last 30 years say. they call this. the end to. his ears i am not interested. i don't believe that gets us where we were and girl as humans are in the new world and not even sure.

watches that mean for our approach to fighting climate change is it better to leave things alone or to intervene and try to limit warming to give ponds and animals in their present climactic zones a chance. in davos a meteorologist is investigating another way of cooling they are. adamant to get worsens or one of my biggest fears about climate. change is that water supplies will become even more unequal droughts floods and especially in terms of our droughts that they'll be moved climate refugees and more wars fought because of climate. thinks it's possible to manipulate cloud formation in such a way that global temperatures for the likeliest candidate seem to be cirrus clouds

so's there is clouds have a greenhouse effect if they hold more heat radiation in the earth's atmosphere then they reflect sunlight. it's the only type of cloud that we know has a warming effect. cirrus are in streaks of ice cloud but for many kilometers above the earth's surface as a t.v. radically if you got rid of all cirrus clouds you cancel out the doubling in c o 2 levels of the. count's have a big influence on climate and temperature the lower ones cool the un they should definitely stay but serious counts have a woman a fact they fold when i just knew clear i am present in the am right when an airplane's turbines condense water vapor. cirrus clouds form naturally in cold humid conditions although they do reflect some some light back into space they only allow some of the thermal radiation from the

earth to escape so on balance sheet or song in order to cool the planet cirrus clouds would be prevented from forming like you parts of the atmosphere could be seeded with desert danced for example the ice nuclei would grow faster become larger and fall to earth as the radiation balance would change and the temperature would drop a little. live there whatever the advantage of sahara dust would be that we know. it wouldn't do too much to the ecosystem it would have no side effects. but when it comes to testing this method out a small scale test would get lost amid the noise of natural variability of the clouds you would really have to do something on a very large scale to see if it worked i'm not sure that that would be possible political. because who would make the decisions which bodies would decide which

individual countries would do something like that in their lands good as all those months. and in any case who would benefit from it in order to answer that question or they can no man wants to learn a lot more about clown on nation this measuring device attached to a balloon uses a laser to examine individual cloud particles it's not clear that thinning out serious pounds in central europe would have an overall benefit and if the seeding was done incorrectly it might cause even more cirrus to form but perhaps this method of halting warming would be effective in the far north. it would definitely make sense to seed arctic cirrus clouds especially in the winter. olympics because we have no sunlight during the winter months so it would really just be canceling out their warming effects and yes we want to preserve the

arctic sea ice of course but there are economic interests in the arctic being never bothered so who wins out. manipulating the warming serious clowns who still fearing but making funded clowns rain down in order to prevent damage from hail has long been practiced in germany so called pale flyers like all get macone show that weather isn't just a question of things so what's in there. you've got the liquid. and acetone solution with 3 percent silver iodide by ports and shoes the earth and lots of. the armor got a pump and a valve controlled from inside or in the hind is a combustion chamber and there's an added miser nozzle where the mixture ignites it to the room. these days people across the won't manipulate the weather china has

a huge government agency that sends rockets into the clown's how and whether the silver iodide works hasn't been conclusively proven it probably creates more ice crystals which become rain more quickly since launch scale hail damage in the area around dawn now and shing on in 2006 there have been no more instances in the region which the joker lent to the figure that because of turbulence the plane gets pulled up towards and also pushed downwards that can cause stalling you have to make sure the structure doesn't get overloaded avoid that the clouds don't pull you into areas where you aren't in control and you have a. whole good macone finds where other pilots wouldn't he tries to spread the silver iodide into updrafts that way it can rise and get distributed into the cloud from a bomb. in one sense climate is nothing but the sum of weather

events to change the climate weather has to be manipulated on a large scale and permanently hail fires only and to influence weather on a local level. but beyond that vibration it what we're doing isn't exactly geo engineering. it's more like protection or trying to change the material state from solid to liquid in that sense the impact on the atmosphere is relatively small if you think but in general i don't think it's a good idea to interfere with the. there globally but. the one on. my list but you guys they're letting a genie out of the bottle and it could have its revenge if things change to the point where people can't control it anymore i don't think anyone wants to experience that. people will probably be prepared to take bigger and bigger risks as the effects of climate change while

some. graziers are melting everywhere like the amish here in the swiss alps the mountains a crumbling. village on the screen a moment you're very moving when i think of the climate and global warming i also think of all these steep mountains where rock falls and landslides can happen and he my worry about the people who live there and. switzerland is one of the european countries most affected by climate change. only if you want to glacier yes you know who go right sun has been observing the on match for a long time over the last 6 to 8 years the glazier mount has again accelerated enormously. so now to the glaciers terminus has receded 3 kilometers sense $870.00 now it loses an average of 50 or 60 meters of length

a year to meet the pulley or sometimes 100 kilometers so all those the size fits on how many years until it's completely gone shrewdness. based on models i think in 80 years it'll be a long way so really tiny kind of a president made your heart bleed with us totally when it hurts to think of a glacier like this which is huge and very beautiful and picture at length on. the effects of. the mounting glazier isn't just an especially problem the mountain where on the most through has started to move an incredible 150000000 cubic meters of rock has become to slide. since 2012 it's happening faster and faster cracks of forming thousands of meters deep in time amount in could come down on the glazier before humans began warming the won't the on that was about 400

meters thick a field that is 400 meters of ice gives about 30 bars of pressure so that 30 bar pushed against the mountain because that pressure is now gone as the glaciers melted the mountain is sliding down to the glaciers terminus so it's just sliding away which turns its own unimaginable forces. it's almost 2 kilometers wide and 1.3 kilometers long and then everything is moving that's unbelievably big. red so listen to the mountain using geophones g.p.s. devices measure the displacement while satellites observe with radon even if the great catastrophe combi stopped the swiss want to be prepared when the mountain collapses they spend 250000000 swiss francs a year on securing their mountains this is only. in the wall for us as

specialists what's happening is extremely striking because you rarely see it it's unbelievable that new fractures are occurring not only in existing weak areas but also right across the goodnight the hard sell models. that. nature is telling us something saying don't turn the heat up any more right right like we're being shown how it will be if we keep on like this yeah. getting the genie back into the bottle here is no easy thing in peru researches are asking how the oceans might help us avert a climate catastrophe that would turn and so on the ocean is such a fascinating. and beautiful habitat impacts on this is i worry that my grandchildren won't be able to experience it and its beauty in all its richness and for literally. from the rain researcher or 3 bezout the plan isn't to cool

off by reducing some light not to mitigate the greenhouse effect itself. he wants to influence the oceans in such a way that they absorb greenhouse gases from the atmosphere and so reduce the very thing that causes the temperatures to rise. there's a need to go so do you do it why so sister i'm excited about the idea as a person to go many people it might sound a bit like playing god let's but after all we change so much on land games deviates or wildly active and don't think twice about land clearing here or creating another manmade ecosystem there goes the steam off power but when it comes to the sea we find it hard to say why we shouldn't make sensible changes for this. the oceans already have gigantic c o 2 reservoirs 50 times larger than the atmosphere they already absorb

a quarter of our greenhouse gases is that the limits of the oceans potential or is it possible to make them do a little more. just . as al had some international research group of 60 scientists and technicians they want to understand how climate change is affecting the special current system off peru. that's best of us the best thing we can do now is to really tap these options and not wait any longer because in 10 years we're going to have to start and. blowing them in 10 years we'll have to begin climate engineering measures these so-called negative emission technologies somehow getting c o 2 from the atmosphere and storing it somewhere else otherwise we're not going to

achieve the climate target set in paris is technically not you don't have a. roof. is to want to officially create a system like the natural one caused by the who pulled current off peru which ensures rich algae growth fish and other marine animals benefit to a smaller government it's an incredibly productive system here nutrient rich water from the deaths is brought up through what's called upwelling that creates a lot of fido plankton growth leading to a very efficient food chain the boat. could be replicated as a kind of global and conditioning system to access the deep water hoses up to 100 meters long would be lowered into the sea. the cold nutrition rich water would be pumped up once floating wind turbines could provide the required energy. when it reaches the surface the deep water would cool yeah but above all it would fertilize

the op unless out of want to come tom would begin to ground absorbing c o 2 from the ass and when it dined it would take the greenhouse gas with it into the depths. there's already a lot of upwelling here but the question is could we do it in regions that are completely unproductive today we call them oceanic deserts they're not dry but they're nutrient poor so nothing grows they make up a good 50 percent of the oceans these so-called deserts. the idea we're looking into is this if you artificially create upwelling there you could absorb more c o 2 and you could also boost the fishing yield. there would have to be thousands of these systems in the us. to make a real difference. in limas military port or 3 bizarre shows us his experimental sent ops the aim of his

research is to better understand marine food chains. cause the floating ranks mizo calls on. this is walk onto visual systems for the op whiling of deep water would look like. to share a smoke pot technically speaking it's possible the question is whether you want to do it the potential of the oceans is huge the supply of nutrients in the ocean depths is virtually an exhaustible now it's ownership. or 3 visible hopes that a significant portion of human made greenhouse gases could be absorbed into the oceans in this way is experiments have already yielded an important finding in order to absorb more c o 2 than is transported upwards from the deep water and the pumps and the hose systems should be repeatedly switched on and off this technique would achieve

a 4 fold increase in the c o 2 uptake of the oceans in these areas as a positive sign to fact fish populations would also be stimulated. but nothing stays on the seabed forever it would be a case of buying time time we desperately need so fond governments have an engaged with the topic of geo engineering there are important questions to be answered like who would decide what measures to pursue who would pay is the un the right institution is what i'm worried about is that my granddaughter who is just 2 months old she will live to the end of the century and i don't want her to live in a world where somebody else decides to spray into the stratosphere and. the planet without asking her. passion or lives on like geneva he was the right hand man to u.n. secretary general ban ki moon now he had some nongovernmental initiative by team to

increase the political awareness of geo engineering. scientific technical engineering issues related to these new technologies are sometimes quite challenging but the governance issues are even more challenging this is part of the culture of managing climate risks that we have to think about and we need options probably and we need more and we need them sooner because we are in for. individual nations manipulated solar radiation on their own yet last passionate fear is that it could unbalance the climate in other countries. what is a plausible scenario is that a country that is baby badly affected by climate change for example a group of small island countries will fix it if they decide to do it and solar

radiation modification is at least a direct costs scientists tell us it's not that expensive so as a medium sized country could do it and wealthy individual could do it to save the world that could be done by a major nation today yes. which brings in problems right of course but but that's true of all sorts of things so there are lots of things in this world that could be done you know utterly day that aren't done david you can all look people in the eye and say the u.s. government you know will do this unilaterally but it will be fair it's a whole world you know i don't think that's at all tibet's us that's a realistic scenario doesn't that it's unable to take advantage of the weather is something that of course gives the nation an advantage if they can do it is. i think it's already being done today because the moment you see the louds to make it rain in the ocean that must have been bound for a neighboring country is gone up by one call you have a company back home that can go you know in the same way that arms dealers go

around the world and say oh well if you want to if you want to be safe you know buyer technology. such unilateral efforts could jeopardize the climate of a neighboring country although the intergovernmental panel on climate change has warned of the risks it doesn't rule out geo engineering as a last result which is something the intergovernmental panel on climate change says must happen in order to prevent global temperatures from rising century after century. almost c o 2 that humanity has released into the atmosphere by burning fossil fuels has to be removed. we've come to iceland to find out how. in iceland's largest geothermal power plant it's already being achieved on a small scale. what i'm most afraid of off when it comes to climate change is

not we will have a large global refugee problem that will turn nations against each other this is why i asked swiss from climb wax tests it's technology it's like a vacuum with circuit in here and this c.e.o. tune is sort of speaks to our services for specific chemical that's in this unit there on the. and then we get the c o 23 year olds on this site. so it all comes through here and it lowers it from $400.00 parts per 1000000 from 2 to less than $100.00 to less than $100.00 you know . that's really hard i mean the concentration of c o 2 is a very little in the air. but still to our yeah it's not a little woods which makes fighter aircraft you're. a bigger technological challenge than cuts in c o 2 from point source of. c

o 2 filters all walk in a similar way there's nothing new about crime watch technology the chemical processes are based on i mean it's derivatives of ammonia combined with c o 2 when the i mean math a full day when they release the c o 2 for final storage the process is repeated thousands of times but the method called carbon capture is very energy intensive each time not c o 2 filtered from the yeah. 2 and a half 1000 kilowatt hours of energy a huge amount so it only makes sense from places with lots of excess renewable energy all waste heat like here in iceland with its infinite geothermal energy. can you imagine on earth where we have hundreds of thousands of these machines yeah i can answer yeah i can yeah. i can i can imagine such

a world where we start to think really locate those new meds we had we have the favorable geological conditions but of course the c.r.c. test to make sense of course but i mean i guess we have to we have to thank big and we have to act big if we are to be successful in getting content. ranch won't be cheap each ton of c o 2 films are by climax costs about $500.00 euro and want them where do we put it the researchers in iceland have found a spectacular with a copper thinks experiment the 1st step is to dissolve the c o 2 and won't water like soda so we inject down 2 kilometer 2 into kilometers. on top of that so it's 800 meter of ground water. meaning what we have very high pressure much higher person here than in here needed to keep everything dissolved into the more or less there's a there's

a lid on the top of. this cave in here and then we have a really the very exciting chemistry happening as well because where it quickly the c o 2 interacts with the purcell fights so in less than 2 years it's turned into a new type of rock and you know once it's rock it's just rock it's not going anywhere. contains lots of calcium magnesium and i am these minerals react with the greenhouse gas theoretical sort of capacity of softs on earth are the a minimum an order of magnitude larger than c o 2 that we would emit if we would were all fossil fuel available. which we hope will never happen so far just 12000 tons of c o 2 power yeah are buried here. to make a difference the number would have to be in the billions concern for the state of

the art is one striving scientists and conservationists might chris tompkins. but her approach to preserving the beauty of nature could hardly be more different she wants swathes of nature to be restored as much as possible to the way they were before human intervention. so when we bought this ranch. all of the knuckle were forced into the high grounds because this was all used for grazing lifestyle. so this was a big fight. between ranchers and conservationists and still is in argentina. that. ranchers see when i go to his competitors. they want to get rid of that everywhere in the world there's this inherent conflict

between conservation felt so. it happens almost everywhere really. the patagonia park shows want challenges have to be overcome to turn back the clock and say what could still be sanct. 600 kilometers of fence sitters had to be removed 30000 sheep sawn roads dismantled and trees planted. it took more than 10 years just for the grasses to return. bringing back 1000 animals has proven to be difficult and. there's now been success with the endangered andean deer humus are also back. after species have to be bred back into the area. here on the argentinian

border of the park but only to south america are being raised. nando's. they have completely disappeared from this area. to the creatures of flightless they have feathers other am only to warm them through the chilly patagonian winter. $6900.00 s. have already been released into the wild the plan is for a population of $100.00 it requires huge effort to retrieve what was once lost. the impacts of climate change the loss of top predators and how that is a cascading effect over all habitat and how it affects human well being as well all those things. it's not something that is going to happen in the

future it's happening now you know a lot of people don't believe that's true but then not believing it doesn't make it he less true are we going to survive actually if you look at the process we've been through to the earth the damage i don't think that's the question i think that's a very anthropocentric question are we going to survive i don't think all of us will why is that why are we doing this. as the question and all the answers at the moment anyway lead me to sink that where willing to risk everything so that we can have a 2nd refrigerator. you know and that's why people young people and old people are in the streets. because how dare you as

correct that says. and chris tomkins himself has no exemption if the younger generation isn't to end up being forced into using geo engineering then climate protection efforts must increase dramatically. and yet the very prospect of technical solutions could stein eat aphids to carbon c o 2 emissions it's a certainty that some people who want to fight against emissions or others like big oil or fossil rich nations may exploit the work we're doing exaggerating how well this works falsely true in a with lies claim that we don't need to cut emissions that's of course complete nonsense we do have to cut emissions but i don't think the fact that people will politically explore this a little bit is a reason that we should you know hear no evil see no evil try and pretend there's nothing here. he's got the call from the moon i haven't given up hope

that looks turn things around in time then is the end if we do i think it would be responsible to do some geo engineering for a ton all just to flatten this peak of warming a little bit with these never albums peak at the top i say temporary solar radiation management ed because removing c o 2 from the atmosphere will have to be done over a long time as all the sea a to leave a message has to be taken out of the atmosphere would one of the deals geo engineering the term geo engineering is a misnomer it will never understand it in terms of going in there like engineers stuff we has to feel our way and learn as we go and we'll have to be able to stop at any time without it coming back to bite us all of us all still that's a basic that's why aren't false notes i'll only consider such measures if we know for sure we can stop without negative consequences were done entirely pseudo help to matusz it was actually. the science is an ambiguous existing measures on to not

to keep the. i'm stable so it's probably only a matter of time until radical geo engineering comes into play how we are in the next few years it's really sort of 515.0 how things on how things might turn out if we are ready to drastically change. our way of living. with you with the museums. put a lot of effort into new solutions that hot available but we need to apply them to a. huge scale and if we do that where is it we will be successful. to destroy beauty and to destroy wholeness. the come around. to counteract this just force of it's going to change. the breakdown of

social structure system and so. on in there is a whole new assistant goodman stan. preston all of us in and in for paying attention to me says certain swing back the other direction. but. who's by our side when life comes 20. has drastically changed death rituals. how are people coping with it. is it possible to die with dignity while practicing social distancing. 3 take
