The planet is training and reveal facts of Climate Change many researchers believe we have to intervene to prevent us from happening which why so many people it might sound a bit like playing god. Manipulating oceans seeding clouds. Creating a sunshade for the art out of salva these are just some of the ideas. You cant tackle something this scale this scale moving this fast. Its just science modifying our climate is it hubris in iceland researchers have already timed Greenhouse Gases into stuff on there that you can see you sort of white spots and thats what the c o 2 we injected into the part of the reservoir thats the solution to apply definitely in my opinion this should be the solution to the plight of the large scale. Scientists want to interfere with the arts processes. Can geo engineering save us not just by getting harmful c o 2 out of the atmosphere but also by cooling our planet. Were on our way to meet some researchers pursuing radical ideas. Im worried that Climate Change has become a kind of political abstraction people have lost track of the drive to protect their part but there are lots. Of Harvard University as one of the most controversial climate researchers believes its high time we had an emergency plan his idea is to create a sort of screen using dust particles which would reflect the suns rays weakening or even Holding Global warming. First big Pilot Project names copecks keeps being postponed and theres still not too much opposition. What it hears is that something that might in combination with emissions cuts reduce the overall climate risk maybe substantially thats the evidence we have required calls so the question is to what extent that solar charger reduce climate rest actually harm people if art like extreme storms extreme temperatures Sea Level Rise those are Research Questions that we dont know the answer to. So called solar radiation management is a gamble Little Research is being done on the risks and yet it could be a last lifeline when it comes to curbing Global Warming. In practice it would mean at least 10000 aircraft injecting the stratosphere every 2 years the planes would release sulfur particles as evenly as possible at altitudes of molten 10 kilometers. These particles would reflect one or 2 percent of the incoming sunlight. 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. Time the global temperature dropped by normal point 4 degrees. In the march and you have to put in there well it depends how much solar we wants so theres 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 its a lot of not a lot. Its were putting billions of tons a year of c o 2 in the atmosphere so one of the ways to think about it is theres 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 so if youre a gas or some other material in the stratosphere so a 1000000 tons is not technologically a lot its doesnt cost a lot but its a real direct perturbation to the environment theres a net tell us also that the stratosphere is just a place you should not interfere because its so sensitive youre speaking as if the alternative is not on interference but the c o 2 is already in the atmosphere even if we cut emissions to 0 tomorrow which is basically impossible but even if we cut emissions very quickly which we could do that doesnt make the climate problem go away and humanity is a long way from 0 emissions once we started pouring some fine into the stratosphere for some change would have to be replaced regularly otherwise temperatures could rise to levels even higher than they would be without the many people ation. For Technology Transit skeptics. My biggest fear is that Climate Change will advance to the point where this planet can no longer sustain human life. To his true jang fuse. But so no geo engineering wont change weather and precipitation patterns damage the ozone now and produce more acid rain some studies show some interest for dru geo engineering is worse than Climate Change itself and even researching the matter is these dangerous governments are watching this closely well companies are watching this closely the military is watching this closely. So theres a political experiment of topping that says you know what what if we could go this route and youre 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 isnt is is research but its also political theater you have that you will never stop people from thinking and from searching for ideas and solutions so the idea of engineering is already in the world so you cant stuff that. You cant stop the idea of doing it in airing 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 to a sharing in it seems like really every major region in the world has their climate risk for at least 7 patients with this leads to a planetary wide experiment you have one planet and youre risking the whole planet to do that experiment for sure solar geo actually has risks but not doing so are you measuring also has. A wearing creasing be a factor of Climate Change we cant accurately predict the consequences of geo engineering. We are on our way to visit an environmental activist whos committed to strengthening natures own capacity to sound buehler. To know what my biggest fear is. Is that the history of the collapse of civilization. Is really repetitive. And were seeing the tail end. Of one of the. Most expansive. Civilizations. In human history. In remote south America Chris tomkins and her husband doug have given vast areas of land by the nature of together with the governments of chile and argentina they created 13 National Parks an area to signs of sorts along. The past was patagonia park since the death of her husband Chris Tompkins lives here alone. Home does to come right on into the house and to please take our shoes off. Its the. Local. Split the end of the world yeah Christine Tomkins was head of the Outdoor ClothingCompany Patagonia husband had founded the brands as free and a north face yet in the 1990 s. They left the business well and went on to invest around 350000000. 00 in Nature Conservation i dont 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 theres no way to turn it back there are no messiahs when it comes to this you cant tackle something of this scale this go moving this fast would just science it would wilson said we should give i think nervous. Back to nature in this size and scale you do it can then make an ecological difference you can enter these places and you understand what is was could be and thats 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 and imams the destruction and inequality in the wild in her mind entire regions should be protected from humans and especially from the clutches of the global minds or economy here on earth cannot save us from climate catastrophe probably not but maybe theres more to it than that its about spacers where Natural Systems can regenerate where we can say for things that represent life on this planet. When. 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 the wrong direction have done for the last 30 years say. They call this. The answer. And it is i am not interested. I dont believe that consists where we want to go is humans are among whom are. Not even sure. What does 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 time out to eat zones a chance. In davos a meteorologist is investigating another way of cooling they are. Item a no go zones are one of my biggest fears about climate. Change is that the oceans supplies will become even more unequal we are droughts floods and especially in terms of our trance that theyll be moved climate refugees and more wars fought because of climate. Thinks its possible to manipulate cloud formation in such a way that Global Temperatures for the likeliest candidate seem to be cirrus clouds sos there is clouds have a greenhouse effect if they hold more Heat Radiation in the earths atmosphere than they reflect sunlight. Its the only type of cloud that we know has a warming effect. Cirrus after winning streaks of ice cloud for many kilometers above the earths surface as are to you directly if you got rid of all cirrus clouds you cancel out the doubling in c o 2 levels of the. Counts have a big influence on climate and temperature the lower one is cool the un they should definitely stay but serious clowns have a woman a fact they formed when i just knew clearly i am present and yeah right when an airplanes tampines condemns water vapor. Cirrus clouds form naturally in cold humid conditions although they do reflect some some bite back into space they only allow some of the thermal radiation from the ark to escape so on balance the heaters are 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 for the whatevers have the advantage of sahara dust would be that we know. So it wouldnt do too much to the ecosystem it would have no side effects of. That when it comes to testing this method out a small scale test would get lost amid the noise of natural variability of the clouds as you know you would really have to do something on a very large scale to see if it worked im 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 this is the land good as it was my home. 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. This measuring device attached to a balloon using a laser to examine individual cloud particles its not clear that thinning out serious counts 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 and so it would really just be canceling out their warming effects and yes we want to preserve the arctic sea us of course but there are economic interests in the arctic being never so who wins out thus convincing. Manipulating the warming serious pound to still theory but making funder ground rain down in order to prevent damage from hail has long been practiced in germany so called hail fires like all get macone show that weather isnt just a question of things so whats in there horgan. Youve got the liquid. And acetone solution with 3 percent silver iodide. Should get there is too much at all you have got a pump and a valve controlled from inside or behind is the Combustion Chamber and theres an added miser nozzle where the mixture ignites the room. These days people across the wont manipulate the Weather China has a huge Government Agency that sends rockets into the clowns how and whether the silver iodide works hasnt been conclusively proven it probably creates more ice crystals which become rain more quickly since launch scale hail damage in the area around. In 2006 there have been no more instances in the region which the talk will lead 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 doesnt get overloaded avoid that the clouds dont pull you into areas where you arent in control and i mean you have a. Whole good macone flies where other pilots wouldnt 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 its what were doing isnt exactly geo engineering or if its more like protection were trying to change the material state from solid to liquid in that sense the impact on the atmosphere is relatively small. Giving but in general would say i dont think its a good idea to interfere with the. There globally. That. One on. My list but the guys theyre letting a genie out of the bottle and it could have its revenge if things change to the point where people cant control it anymore i dont 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 mounting everywhere like the on edge here in the swiss alps the mountains a crumbling. Village on the sickly a monteverdi one day when i think of the climate and Global Warming i also think of all these steep mountains where rock falls and landslides can happen i 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 to that song has been observing the on match for a long time over the last 6 to 8 years the gracie amount has again accelerated enormously did so well to decide the glaciers terminus has receded 3 kilometers sense 870 now it loses an average of 50 or 60 meters of links a year to meet the police sometimes 101 wholl listen this size fits all how many years until its completely gone shrewdness. Based on models i think in 80 years itll be a long way so really tiny like a bit of blue isnt it maybe your heart lead us to think when it hurts to think of a glacier like this which is huge and very beautiful and picture at meetings on. The effects of. The mounting grain santa isnt just an i spent a problem a mountain where on the most frugal has started to move an incredible 150000000 cubic meters of rock has become to slide. Since 2012 its happening faster and faster cracks of foam and dozens of meters deep in time mountain could come down on the glazier before humans began warming the wont 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 its just sliding away which turns its own unimaginable forces. Its almost 2 kilometers wide and 1. 3 kilometers long and then everything is moving thats unbelievably big that orse. Had so listens to the mountains using geophones g. P. S. Devices measure the displacement while satellites observe with radar d even if the great catastrophe combi stopped the swiss want to be prepared when the mountain collapses they spend 200 50000000. 00 swiss francs a year on securing them mountains this is still only. Enough for us as nationalists whats happening is extremely striking because you rarely see it its unbelievable that new fractures are occurring not only in existing weak areas but also right across the goodnights the hard. Nature is telling us something saying dont turn the heat up any more right right like were being shown how it will be if we keep on like this yeah i suppose. 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 the society worry that my grandchildren wont be able to experience it and its beauty in all its richness and for literally. 4 Marine Research or 3 bezout the plan isnt 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 temperatures to rise. Theres an age to go so to do choicest im excited about the idea as a person to go many people it might sound a bit like playing god lets but after all we change so much on land. Deviates our larvae are wildly active and dont think twice about Land Clearing here or creating another manmade ecosystem their system of power but when it comes to the sea we find it hard to say why we shouldnt make sensible changes for those. The oceans are already a gigantic c o 2 reservoir 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 pos
