the livelihood of around 56000 people who work in german professional football. and you are up to date this is state of the news in berlin a quick reminder that you can get news and features around the clock that's on our website at www dot com and with the dave and on twitter that we're at the news i'm christine one block from myself of the team thank you for watching it's been great having your company see the stock. beyond p.r. cancel. all of the stories that matter to. whatever it takes. to run enough. to. know that.
8:16 pm
you made 4 mines. every. fortune this is your attitude. it's in the order of all your go south to work good on the t.v. but there's still. more work for. paris december 25th in the 196 countries signing the paris climate agreement agreed to get global warming under control well below 2 degrees celsius by 2100 the effect that he has on the system is something that's happening more rapidly than some of the changes we would like to meet nearing is the only fast acting approach to reduce heat directly in the climate. whether they're harnessing the. excess c
8:17 pm
o 2 in the atmosphere calling the earth artificially the common goal of geoengineering technologies is to slow down or even reverse the effects of global warming by deliberately intervening in the climate what it's meant to do is give us to be able to go to the energy. to limit the damage. to. coal oil gas the global economy is addicted to fossil fuel energy far from slowing down global emissions of carbon dioxide continue to increase to curb the effects of global warming scientists are now looking for ways to remove
8:18 pm
the excess c o 2 present in the air. yes it ridiculous the carbon cycle which is very active on earth with several reservoirs a huge reservoir in the oceans with the carbon dissolved within the water there's another reservoir on land in vegetation and in sorrels and then there's atmospheric c o 2 ever since we started using fossil fuels we've been sending carbon into the atmosphere going to. the oceans biomass and soil do not have the capacity to absorb the excess carbon that has built up in the air since the beginning of the industrial revolution. since $850.00 the c o 2 concentration in the atmosphere has increased from $280.00 parts per 1000000 to more than $400.00. dioxide piles up in the out. it
8:19 pm
is cumulative it doesn't go away roughly half of the c o 2 we put out will be there for hundreds of years and together really out of the atmosphere ocean biosphere systems will take tens of thousands if not hundreds thousands of years so we need some ways of taking carbon dioxide that already entered the environment back out and broadly speaking that is a negative emission forecast by the intergovernmental panel on climate change or i.p.c.c. suggest the concentration of atmospheric c o 2 could triple by 2100 if no action is taken to reduce emissions that would result in a temperature rise of over 4 degrees celsius. every scenario that keeps global warming below 1.5 to 2 degrees involves a number of ways of carbon dioxide removal in order to reduce and emissions should they increase to munch over the course of the 21st century. since it is more than to be the most commonly used method in these integrated climate carbon models which
8:20 pm
simulate different scenarios is to use biomass via reforestation and asked for a station to generate negative emissions through what's known as beck's. stands for bio energy with carbon capture and storage plants are grown to absorb c o 2 through photosynthesis then they have burned in thermal power plants to produce energy the c o 2 emitted via their combustion he's captured and stored away the carbon footprint of this process is negative. growing trees is generally a good idea and you're not going to find too many people arguing against you but this is can you do it at a scale which is actually going to have a material impact the problem is that you have to grow such a huge area of these plants that it's going to have impacts on other systems in terms of biodiversity and in terms of land tenure so that. land belongs to someone
8:21 pm
at the moment and the issue is well how is it going to be affected by people using that land to take carbon away did a small scale and it probably doesn't have much of an effect but try to do it on a scale that has in the tiriel impact on the climate which is what this is about and it would have a material impact on those officers. to remove $10000000000.00 tons of c o 2 per year or one quarter of all current c o 2 emissions we would need to set aside $500000000.00 hectares of land equal to a 3rd of all current farming land or an 8th of the world's forests add to that the intensive use of fertilizers and tensions over water resources. another method involves capturing c o 2 from using chemical processes a researcher at arizona state university klaus lackner has developed a prototype that can replicate the c o 2 absorption capacities of
8:22 pm
a tree leaf but far more effectively. directly accurate picture is a set of technology to literally pull thier true directly out of the ambient air by technical means you can always use it this is an alternative for the synthesis you could grow bio mass you can grow plants and be collect c o 2 from there just as well so we are calling our direct capture artificial trees because just like a tree we take thier true out of the as the wind blows over our artificially thereby c o 2. in the mid 1990 s. the physicists discovered the specific properties of a polymer that could absorb carbon dioxide when it's dry it absorbs the c o 2 held in the air when it's wet it releases it again. this is a very tiny capture device grams per day.
8:23 pm
and now i'm driving it into its parking spot where we can where we can now we generated and in order to do that we have to make it way. so now that reach the top i simply let go from the pump and now gravity drains have back you see the water coming back and going down there and we're simply watching this building up the c o 2 level inside and right now it has we just 1.9 percent so it's going to breach 2 percent so we're about 50 times higher than we are in the ambient air inside this little box and the only thing we did is we made the resin material but. unlike other methods of managing the climate this one is simply walking us back from where we shouldn't be in other words we dumped too much c o 2 in the atmosphere and now we're taking it back out and i think sort of from a. conceptual point of view this is the least invasive method to solving the
8:24 pm
problem to test out these techniques which has proved successful in laboratory tests engineers have developed a prototype and set it up in the desert unlike other techniques this device will be able to absorb c o 2 without consuming too much energy. energy required to capture the carbon dioxide is provided by the normal. movement of the wind other words the wind evaporates the water off of the resin surface we speed high the carbon dioxide that it can carry them and the energy of the gap aeration is the energy that causes that kind of loop if you will so we let the wind do that for us we harvest the wind . how effective could these machines really be engineers hope to get them into mass production as quickly as possible to remove c o 2 from the air. what scale it up so that it was so. thing that would fit inside
8:25 pm
of a 40 foot shipping container a machine that size would capture roughly a ton of c o 2 a day so one of those machines would cover in 6 days would cover the output of an automobile for an entire year. inspired by this discovery architects of now designs tree pullets artificial trees planted in the cities of the future a project that for now remains a vision of the future. become a problem is a waste management problem and i'm all for minimizing the waste we are making and moving away from fossil fuels as fast as we can but between the time we succeeded with the transition and now we will emit so much more c o 2 that we have to in the meantime clean up all the litter you generated in the past you have to take back because we can't leave it where it is and that means we have to do but we have to go to sustainable solutions and at the same time clean up
8:26 pm
after ourselves and this is where capture comes in in the short term. what do we do with the c o 2 once it's been absorbed by these machines 3 private companies have become involved in direct capture in 2010. founded the company global thermostat whose aim is to suck up c o 2 and sell it on it's a 1st step towards a carbon neutral economy if you remove this you're. going to use a commercial for drinks very juice. for food bank going to hamburg nurse did use dry ice this year do for the salmon 18 want there which is essential for humans for production of 40 murders for plastics we chat about you to get a good walk for by your fertilizers are being treated increased differently if you're fish so. to produce clean fuel rods very mixing this year do we have
8:27 pm
hydrogen you are removing the c o 2 and you're making profits. directing a capture technology uses ammonia based chemical processes global thermostat has already filed 35 peyton's and amassed 51000000 euros to develop its technology the same way that the doctrine of the illusion led to the use of pretoria i say feedstock. for the whole of cornering to good use sanitation and material to tip it out instead of using pictorial you can use your therefore you can have a world in cornering that is powered by the c o 2 that we take for mere. increase economic growth enormously white cleaning the atmosphere and that is the evolution of discovering that's the revolution we want to be part of according to
8:28 pm
a 2011 report by the american physical society the cost of direct capture would be around $400.00 u.s. dollars per ton. the expectation is that direct capture will be very expensive the kid no one is prepared to pay for removing c o $2.00 from the atmosphere there's no incentive it's as if you've got lots of different machines for cleaning the streets of rubbish but nobody is prepared to pay for picking up the rubbish and ultimately you need to have some sort of mechanism that recognizes that syria too in the atmosphere is a waste and that we need to remove some of that waste for the benefit of society. recent reports written by industry itself suggest that it may be possible to reduce the costs of direct capture to around $100.00 or even $50.00 per tonne thus making the technology viable. in order to shift towards negative emissions and have an
8:29 pm
impact on the climate direct capture must be accompanied by a long term storage system. the helis haiti geothermal power station supplies a 3rd of iceland's electricity. as part of the carb fix research program icelandic engineers in partnership with the european union have developed a technology to inject the plant's emissions directly into underground rock. the swiss company climb works to set up a system that captures c o 2 in the air and buries it. here perhaps just 50 tons of c o 2 per year and it is maybe offsets that the 30 cards with this you can capture emissions from france or china or whatever because it's. in the atmosphere around the globe. you just install this wherever you have a little bit conditions what it's going to show and then you have it using
8:30 pm
a filter and the power plants energy the c o 2 is captured and injected into subterranean layers of bass salt more than 4. 100 meters below ground so this year to come from the plant this year to is mixed with what there it goes into a steel pipe into the bathroom the c o 2 in this fluid it sit but it creates acid and this assett this solves the rocks and then rocks the lever cut them into this and they bind immediately with. another rocks. you can see here you have these small purples this is going to be have space for the c o 2 from the air to press it it and you can see these white spots this is colored sets a sense and it just calcium carbonate so it has calcium from that rock that it is solved and then c o 2 is converted to solid rock it stays there forever it's not going to leak to the
8:31 pm
surface and come back so we have to capture it again and we inject it we just captured it injected mineralize it and it's gone. climbing believes this research project is a 1st step towards a world of negative emissions the company has set itself the objective of capturing one percent of global c o 2 emissions but reversing the effects of 200 years worth of burning fossil fuels will take time and a lot of money. this is why others are looking for solutions elsewhere in the oceans for example. the way the ocean works because there's sort of nutrients in the deep ocean but nothing can do for the synthesis there because there's no light at the surface of the ocean there's a lot of life but there's not much in the way of nutrients if we put some
8:32 pm
additional nutrients in the surface that could allow organisms to photosynthesize take the c o 2 turn it into a. organic matter and then that would sink into the deep ocean pulling that carbon out of the atmosphere. in british columbia in western canada the private organization. is developing a fertile insulation technique that would allow oceans to absorb a large amount of carbon we have been working for the last 2 years on a specific ocean seeding compound that provides irony not in the form of rust but in a bio to bio available for. coal iron to irenaeus is heavy and iron. sinks quickly so what we did was we found a process that we can buy these are in with organic material or like water built for instance that floats and or it sinks lower basically and it keeps that bioavailable irony available for
8:33 pm
a longer period of time instead of hours it keeps it available for you know for for several days in a photograph. will the supply of ion enable the find hope plankton to grow faster and absorb c o 2 before drifting to the bottom of the oceans in theory each ton of iron added to the oceans could remove between 30110000 tons of c o 2 from the atmosphere. ocean for lies a ship is probably the only carbon capture technology that's able to sequester a message and mount a c o 2 at a very low cost and as a by effect probably improving the very ecosystem as well we've developed a methodology where we can tag and measure if a fish grew as a result of our claim to bloom and in the process of growing that that claim to in its consume c o 2 and eventually these diatoms these days he's playing to those who will die and they will a portion of that will sink to the bottom of the ocean sequester the carbon there
8:34 pm
for you know long periods of time. to date a dozen experiments have taken place to test the impact of ocean fertilization on marine ecosystems in 2009 the indo german program loha thinks gathered new data research has poured more than 6 tons of iron into a 300 square kilometers stretch of ocean this led to a doubling of fighter plane 10 in just 2 weeks but the results of the experiment demonstrated that only a tiny amount of carbon actually reached the ocean floor. citic need to know yet how effective these ocean fertilization technique really is and in no doubt. comes with a lot of syria's disadvantages because it involves up setting and librium within our oceans ecosystems it will favor invasive species and shift the balance between certain species. of. oceania hopes to carry out several ocean
8:35 pm
fertilization experiments in the years to come but using human intervention to restore ecosystems and remove c o 2 has raised concerns among environmental groups one of the things that a lot of people don't understand is that we only are going to buy one cup of irish about the size of a soccer field. and i think that who idea of overpromising issue that we're pumping like massive amounts of chemicals it was really not correct and that's a misconception that the public has. the oceans have absorbed a large proportion of global carbon emissions over the last few decades according to recent studies they show signs of reaching their saturation point in c o 2 which is one of the leading causes of ocean acidification. we can't be sure that this fertilization will be enough to recover this process.
8:36 pm
meanwhile and other researches are already coming up with ways of lowering the earth's temperature. so we have a problem that the atmosphere has gases that are trapping heat and we like to take those gases out of the atmosphere and restore the balance of healthy stuff but taking the gases out of the atmosphere takes a long time nature takes a long time to bring them out and artificial methods have to be created and distributed if we can bring them out so if if we need to address he then we may have to more quickly then those options for bringing greenhouse gases out of the atmosphere solar geo. engineering reflecting sunlight from the atmosphere is today the only known way to within a decade or 2. the solar radiation that reaches our planet is not completely absorbed by the earth's surface some of the sun's rays are reflected back into
8:37 pm
space by the atmosphere and land surfaces a phenomenon commonly known as the albi dome effect. in 1965 a scientific report sent to us president lyndon b. johnson was already warning of the dramatic consequences of rising c o 2 levels in the atmosphere it suggested for the 1st time increasing reflectivity by one percent in order to cool down the planet in 1998 we were in aspen and we had a meeting about how to. solve the climate problem and most of the talks were about transforming the energy not cutting down far but there was one talk somebody proposed putting some kind of shield to deflect sunlight away from the earth. astrophysicists global would propose the idea of parking a space sunshade at the point where the gravity of the earth and the sun cancel each other out. point one. so i got back to my office and we didn't have
8:38 pm
any money to work on this or anything and but the guy who had the next office over to me he was running climate models and we were really surprised at the outcome because it worked much better than we ever thought. in caldera is one of the founding fathers of geo engineering shortly after the new millennium began he carried out the 1st simulations of solar geo engineering he demonstrated that it was possible to limit global warming simply by diffusing the sunlight some parts of the earth system like the coral reefs the ice sheets are facing. tension collapse within 20 or 30 years maybe we want to have emergency options then these kinds of options are the only thing that are known to work that quickly and in marine collaborating you could break clouds over 20 percent of
8:39 pm
the clouds in the ocean maybe 3 or 4 percent of the ocean's surface and possibly cool the entire planet by 2 degrees. influencing the reflectivity of marine clouds to make them brighter was one of the 6 solutions chosen by the australian government in 2018 to save the great barrier reef already showing the effects of global warming. in the u.s. researchers for the marine cloud brightening project have developed a floating offshore device to enhance the reflectivity of ocean clouds. clouds cover about 2 thirds of the earth's surface so anything you can do to change the brightness of those clouds can change the amount of sunlight being reflected back to space they already reflect
8:40 pm
a lot of sunlight back to space so they act to cool the planet actually cool so brightening is the idea that if we change the number of particles in those clouds the number of droplets the concentration of droplets we can actually make those clouds brighter. each one of these little trikes is the effect of one single large container ship over the ocean. you can see that the brightness is increased where there are tracks showing that particles have been emitted by ships and going into these clouds and making them brighter. but what we want to do is to take salt from the ocean which is already a natural. sauce of these clouds forming particles and we want to increase the number of those and by doing that deliberately increase the brightness of those clouds and if we increase the brightness by a small amount we could offset some of the warming due to the common outside so we
8:41 pm
might go from reflecting let's say 25 percent of the solar radiation to 50 percent of the solar radiation that's a lot in terms of energy but it's still allowing solar radiation through to the ocean. convinced by the potential of this method a team of retired engineers from silicon valley have joined the project to help develop a system for diffusing particles if you go to the coast of california. and this is the clots that we preferably would like to work with so these clouds are not very reflective so they look great they don't look quite so if you get more droplets and smaller droplets that the recall wife. this is our knowledge in the hood here that has 2 connections one providing compressed air and vigor 2 from the smaller 2 providing salt water and they mix some in oslo and come out as a spray so to get it to work jack will turn off the press air 1st.
8:42 pm
using this invention the engineers say they are able to spray nano particles 15000 to the millimeter wide small enough to rise and remain suspended in the end. the team hope to carry out a full scale experiment within the next few years to act upon cloud reflectivity. ultimately the engineers are hoping to develop a system capable of spraying more than one trillion seawater particles per 2nd. it would be some time before we do it has that's big enough and those are whether we're brightening clouds and in order to do that you need a big pots of cloud and sky 100 kilometers by under kilometers which is big for humans that is small for the earth and you would go out in the remote ocean where the clouds are very clean and pristine and you generate spray from the ocean
8:43 pm
seawater with 4 or 5 ships and you traverse this area for several months. i personally think that it would be somewhat irresponsible for us to think about doing the solar climate engineering if we are not at the same time rapidly moving towards the idea of removing carbon dioxide from the atmosphere so if you imagine you are trying to compensate for the warming due to c o 2 by doing marine called breaking every year there's more c o 2 in the atmosphere so every year we would have to make brighter brighter clouds eventually going to run out of clouds to bright this is not going to work. in 2006 nobel prize winning. mr cole crewdson known for his work on the ozone layer raised the possibility of spraying into the stratosphere to reflect a portion of solar radiation and cool down near.
8:44 pm
a particle suspended in the air in the lower part of the atmosphere the troposphere or the upper part of the stratosphere. that atmosphere in the stratosphere which begins around 10 kilometers above the earth particles move around horizontally rather than falling straight back down to earth. and one thick card that we do you know steve all the climate models. and this way we can simulate for example in the present climate that we can also simulate future . we cannot really test. in that way but it would be flawed because that would mean we would have to inject a large amount of gus's or air assault in the stratosphere but we don't know what it does and we don't know what the impacts are so best to really right now and use crime or large amounts to simulate the effect. this
8:45 pm
example shows the spread of a cloud of aerosols from a single source over a 2 year period the particles move around horizontally within the stratosphere and end up covering a large part of the earth's surface. we explored how you can inject gases at a certain location to then change their all sorts or you would actually control the movement and get the cooling you want to. controlling the injection and spread of aerosols within the stratosphere to reach optimal coverage is one of the challenges currently faced by geo engineering. inject the air assaults here. and 15 noise and you can nicely see the arrows don't just cover this one latitude while the engine acting very close to the tropics but and then if we continue in the next year to inject in the other hemisphere in 15 north you can see
8:46 pm
also how quickly those 0 salts move around the globe and then slowly also cover the other part of the hemisphere and in this way we eventually can reach a global coverage with the 0 salts and reach global dimming. injecting sulfur dioxide kelsie in carbonate or even diamonds many different types of particles of being looked into engineers believe this can be done using airplanes or pipes elevated by balloons. why wouldn't you want to just do it tomorrow if it's so wonderful we're not really sure what the side effects will be with the earth system is an incredibly complicated system in our models and very complicated but our models are just a very crude representation of all the rich detail of reality and so we can be sure any time you interfere in a complicated system that something's going to happen that you don't expect and so
8:47 pm
from an environmental point of view the thing that i'm most concerned about are unintended consequences there could be long term effects on ecosystems that we don't know about. if they were to be deployed in the near future sulfate aerosols could. alter the chemical structure of the stratosphere and therefore slow down the progress made in rebuilding the ozone layer. depending on the size of particles used the brightness and color of the sky could also change but we also know very little about the toxicity of these aerosols once they fall back down to worth. several 1000000 tons of particles could maintain or even lower land temperatures even if greenhouse gas emissions were to double. the riskiest along the plights year engineering the more we inject the more dependent we are on your engine and keep doing this and the most important part of
8:48 pm
flying to engineering to me is that we have the same time reduce greenhouse gases that eventually get stopped. the terminations effect if after 50 years of solar geo engineering we stop releasing aerosols into the stratosphere the temperature will rise by more than 2 degrees in under 10 years. then within say 10 to 15 years all the warming we suppressed and try to avoid by injecting aerosols into the stratosphere will eventually catch up with us. so that external data source such as rapid warming also means it's much more difficult to adapt to global warming difficult for society and for natural ecosystems because of this report. little by little geo engineering is now establishing its place in the global warming debate a small group of researchers mainly in north america europe and china are starting
8:49 pm
to take it seriously research into geo engineering has arrived at a turning point where experimentation appears to be essential should we prevent these experiments all regulate them. going out in the open during doing outdoor field trials is a red line it's a political red lion that will sort of normalize the idea of doing interventions and you know the beginnings experimentations get the war you know the work that ability that is being 'd lent to that all out experimentation should not go ahead. you know before we've had an international conversation about this topic . controlling the climatic thermostat will require new legal provisions international agreements and treaties thus providing a framework for future experimentation. if you asked me today to vote whether to start solar juge nearing tomorrow or next
8:50 pm
year what would never ever do it frankly i would vote for never ever doing it because we simply don't know enough solar geoengineering reverses most of the problems. we know about most of the characteristics of climate change on the one hand or climate policy on the other right that it is slow it is expensive it's global it takes right incentives to put people together that perry's agreement was all about getting countries to agree to do more than the otherwise would while all these properties reverse when it comes to storage and. it's quick it's cheap. the quantities involved of arrows austin need to be lofted into the stratosphere are relatively small you know less than 10 points flying year around the world a living material into the stratosphere and it isn't perfect is not
8:51 pm
a solution to climate change the real problem is stopping people stopping countries stopping overall action that might be too quick too fast. and not done in an appropriate way. costing much less than current policy on reducing c o 2 emissions. engineering and particularly the technique of stratospheric aerosol injection would be accessible to any country. 'd and point can this get out of hand how can we prevent other actors powerful states military actors over corporate actors to use their technology and their interests at and have already been very uncertain. in the various technologies uncertain you
8:52 pm
know types types of the hardware or certain processing certain aspects of that technology. geo engineering is for the most part funded by private donors microsoft co-founder bill gates has invested millions of dollars into funding this research a study in 2014 identified $143.00 patents relating to geo engineering technologies primarily in the field of carbon dioxide removal. in silicon valley the company ice 911 has developed a controversial geo engineering technique. i started when one in 2006 when i saw the l. gore including. truth movie one of the things in the film that really stood out for me was the ice l.b.o. feedback effect when the summer sun is shining on this now darker ice and ocean more solar energy is being used or rather than reflective ringback ringback the
8:53 pm
nonprofit is developing a protective material that can be scattered across sheets of ice in order to restore its reflective properties ringback. so these are material that are fundamentally like sand but it has an inert gas bubble in the middle of it and a thin shell of silica around it and when we put it in water it will float can then make a profound protection of ice and snow underneath because it makes it reflective bright enough they are reflecting off the sun like. off to several tests in alaska the company funded by private done is he's waiting for permission to test its geo engineering process on a greater scale. this time in the giant in the middle of the arctic ocean. we just got news this winter that the arctic formed virtually no new ice and the amount of ice that is in the arctic in the summer determines how stable our climate
8:54 pm
is how much cooling we have how much solar radiation is reflected back to space so you want as much ice there as possible in the summer and in order to do that you need to form the most in the winter and what's one of the ways you can aid that process you put this material on top so you call that surface layer and more build from underneath. look how much brighter the material is in the surrounding area. and the size of deployment we're thinking of are things on the order of half a percent of the area of the arctic you know in strategic areas that could make a very large impact and we're showing in the climate modeling the ability to rebuild not just ice area which happens in some sense every winter you rebuilt the nicer. all over the arctic but very importantly ice volume and it set ice thickness that allows you to build back to having a high reflectivity a 2nd high l.b.o.'s is what the experts call it that's what we're after trying to
8:55 pm
rebut that process. or ice 911 hopes to ultimately acquire between 3 to 6 container ships to help scans of these glass micro beats and in its own words save the arctic. the idea that we may be confronted with a climate emergency in the next few years is spreading and the public debate on geo engineering has only just begun. thanks. for this to ask you how much would it cost to build a large gigawatt power nuclear power plant in germany the answer is well you can't and the reason you can't is not because the germans don't have the technical ability and not because they don't have the money it's because they don't have the political will they've made a decision they don't want to do it so for a technology to work it's not about kind of work just physically it's also about whether it can work socially and politically as well the question is can it be done
8:56 pm
in a way that would be socially acceptable politically acceptable would it how how would it actually happen would you have one country deploying it in other countries just going along with it or would you have an international agreement and how would it be structured lots of questions about well how do you maintain the system. if you're going to have such a system what rate do you you set it up to say you want half a degree of warming one degree one and a half degrees who decides. to get stepped over his menounos reason to believe that we won't be able to reduce it all employment alternatives. by nailing that woman i'm an alexander the problem is that the i.p.c.c. has considered various carbon geo engineering options. but isn't studying other alternatives no less included come up more to him for example extensively supporting acro ecology and non industrial farming like the compass in all taking
8:57 pm
measures to salvage damaged ecosystems such as wetlands and forests. that there are more but i have no wouldn't. want snow that would create jobs and enhance the wellbeing of communities that live in these areas that it's not just a question of absorbing c o 2 i think hardly any of these options have been studied. i understand that there are researchers who may be well intentioned in their line of thinking but only want to understand how the technology works. better in a way but the impact that has on the real world is terrible once again there's an injustice between the victims of global warming in the south and those who have the resources to research it in the new modern and not. the inertia and inability of societies to act on the causes of global warming or pushing others toward climate control but is geo engineering humankind's final step towards controlling nature
