The planet is training on to view the facts of Climate Change many researchers believe we have to intervene to prevent must from happening which why so many people it might sound a bit like playing god. Manipulating ocean seeding clouds. Creating a sunshade for the oft out of self these are just some of the ideas. You cant tackle something of this scale this girl moving this fast. Just science modifying our climate is it hubris in iceland researchers have already timed Greenhouse Gases into stuff then you can see sort of white spots and thats what they see it to be injected into the part of the reservoir thats the solution to apply definitely in my opinion this if you want to see the life of a large scale. Scientists want to interfere with the ox process and. 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 Research Just pursuing radical ideas. Out more of the Climate Change has become a kind of political abstraction it all has lost track of the drive to protect their bar but they love david keith a Harvard University as one of the most controversial climate researchers in 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 if yes is it something that might in combination with emissions cuts reduce the overall climate risk maybe substantially thats the evidence we have acquired calls so the question is to what extent that solar church or reduce climb everest actually harm people in iraq that 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 has been dom on the risks and yet it could be a last lifeline when it comes to curb 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 more than 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. So much that 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 tons a year which is that a lot 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 times its 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 now 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 client all them go away. And humanity is a long way from 0 emissions once we started pouring some fine into the stratosphere or some shade would have to be replaced regularly otherwise temperatures could rise to levels even higher than they would be without the many pilate. The technology present skeptics. My biggest fear is that Climate Change will advance to the point where this planet can no longer sustain human life. To various true jan a few years that so no geo engineering will change weather and precipitation patterns. Damage the ozone layer and produce more ascii drawing some studies show some interest for dru geo engineering is watch the Climate Change itself and even researching the matter sees dangerous governments are watching this closely well companies are watching this closely the military is watching this closely. So theres a political experiment the 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 is an 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 the engineering is already in the world so you cant stuff that. You cant stop the idea of do insuring from existing but but what you can stop is that 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 reduced fermentation 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 jewish or it also has risks. We are increasingly aware of the 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 know what my biggest fear is. Is that the history of the collapse of civilization. Is really repetitive. And were seeing the tail end. The most expansive. Civilizations. In human history. In remote south America Chris tomkins and her husband doug have given vast areas of land to nature together with the governments of chile and argentina they created Team National parks an area the size of sorts in. The past was partly go in your pocket since the death of her husband Chris Tomkins lives here alone. Shes told us to come right on into the house and to please take our shoes off. So there its the. Locals. 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 better there are no messiah. When it comes to this you cant tackle something of this scale this go moving this fast. Just science would wilson said we should give i think having earth. Back to nature 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 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 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. 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 save the things that represent life on this planet. We believe that all life has Intrinsic Value the non 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 age of the n. T. And it is. In the interest of. I dont believe that gets us where we want to go its humans are in the new world theyre not even sure i. Want to start 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. Item a no go zones are one of my biggest fears about climate. Change is that the Water Supplies will become even more unequal more droughts floods and especially in terms of our droughts that theyll be moved climate refugees and more wars food because of climate. Greater low money thinks its possible to manipulate cloud formation in such a way that Global Temperatures fold the likeliest candidate seem to be cirrus clouds sos more serious clouds have a greenhouse effect because i 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 when streaks of ice counted for many kilometers above the earths surface as a t. Of the radically if you got rid of all cirrus clouds you cancel out the doubling in c o 2 levels above the. Counts have a big influence on climate and temperature the lower one is cool of the un they should definitely stay but serious counts have a woman a fact they formed when i snooped li i am present in the yam might when an airplanes turbines condense water vapor. Cirrus clouds form naturally in cold humid conditions although they do reflect some sunlight 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 likely 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 hail the radiation balance would change and the temperature would drop a little. Live for the whatevers have the advantage of her a dust would be that we know. It wouldnt 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 im not sure that that would be possible political. Because who would make the decision was in the end which bodies would decide which individual countries would do Something Like the land. 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. This measuring device attached to a balloon using a laser to examine individual cloud particles its 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 serious to form but perhaps this method of halting warming would be effective in the far north. It would definitely make sense to see the 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 Ice of course but there are economic interests in the arctic being never bored so who wins out. Manipulating the warming series pounds you still fearing but making funda clowns rain down in order to prevent damage from hail has long been practiced in germany so called health lions like all get macone show that weather isnt just a question of thanks for whats in there or go oh. Youve got the liquid. And acetone solution with 3 percent silver iodide by ports and you should get there is the attitude youre got a collar and a valve controlled from inside or behind is a Combustion Chamber and theres an atom iser nozzle where the mixture ignites the norm. These days people across the world manipulate the Weather China has a huge Government Agency that sends rockets into the towns 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 but the top will enter the figure 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 you have a. Whole good macone finds 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 pale fires only end to influence 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 if you think but in general i dont think its a good idea to interfere with the way. There globally. That. One on. My list but you 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. See as a melting everywhere like the amish in the swiss alps the mountains a crumbling. Village on the sickly a moment of it one day when i think of the climate and Global Warming i also think of all these steep mountains where rock falls and landslides going to 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 edge for a long time over the last 6 to 18 years the glycine amount has again accelerated enormously. So well just cite off to the glaciers terminus has receded 3 kilometers sense 870 now it loses an average of 50 or 60 meters of length a year to meet the police sometimes 100. And so the size fits all how many years until its completely gone the shrewdness. Based on models i think in 80 years itll be a long way so really tiny line about a president make your heart bleed thats 2 thing and it hurts to think of a glacier like this which is huge and very beautiful and picture at mango on. The effects of. The mounting isnt just an especially problem the mountain where on the most flu has started to move an incredible 150000000 cubic meters of rock has become to slide. Since 2012 its happening faster and faster cracks of forming dozens of meters deep in time amounts in could come down on the glazier before humans began warming the wont the on that was about 400 meters thick a field that i use 400 meters of ice gives about 30 bars of pressure so that 30 bar pushed against the mountain dew because that pressure has 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. Fossett almost 2 kilometers wide and 1. 3 kilometers long and then everything is moving thats unbelievably big. Red zone listens to the mountains using geophones g. P. S. Devices measure the displacement while satellites observe with radar 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 them on tunes this is only. In the wall for us as specialists 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 united the hard. Nice sort of. 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 theyre also on a so i and the ocean is such a fascinating. And beautiful habitat impacts organises i worry that my grandchildren wont be able to experience it and its beauty in all its richness and for its early. Fall 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. As an h. The guy said you do it why such as im excited about the idea solicited so many people it might sound a bit like playing my god lets get after all we change so much on land do you view our 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 the surface of. The oceans are already a gigantic c o 2 reservoir 50 times larger than the atmosphere they already absorb a quarter of all Greenhouse Gases is that the limits of the oceans potential or is it possible to make them do a little more.
