Is dying up the warning from scientists returning from the largest ever expedition to study Climate Change toronto north pole. I mean a phenomenon welcome us president as back on the campaign trail 10 days after it was revealed he was positive for corona virus he traveled to the key battleground state of florida where he held a Large Campaign rally before he left washington trumps medical team said he had tested negative for covert 90 meanwhile his democratic rival joe biden appeared at an event in ohio and other swing state 3 weeks ahead of election day early in person voting has already begun in some states like here in georgia. Im now joined by g. W. Correspondent in our Washington Bureau at a frozen trumps florida rallied white tells doctors gave an update on his health what exactly did they say. They said that trump tested negative on consecutive days using rapid tests now these tests are less reliable than tests where the results might take a little longer to get so theres been some criticism even though. There was a just one negative results you know negative results on consecutive days and the white House Doctors conclusion from those is the trumpets no longer and fractures. Floridas one of the top college prices holes chump doing there and what does that say about the state of the race. Its really no coincidence that trump is holding his 1st big rally after his covert 1000 diagnosis in florida because he is behind there he is trailing democratic candidate joe biden by by roughly 4 Percentage Points and this gap has been growing now florida is a crucial swing state with 29 votes in the Electoral College and this is really bad news for as a Trump Campaign because if he doesnt win florida its really highly unlikely that he could still get reelected in november you mentioned jim tell us about joe biden where was he complaining today and what was his message. Joe biden was in another crucial swing states today he was campaigning in ohio and in ohio the situation looks a lot different than it does and florida here the 2 candidates are neck and neck theyre separated by less than one percentage point. And joe biden was speaking in front of supporters who were in cars so you know people sitting in their own cars and social distancing that way which is very different than what weve seen from from recent trump events and biden was calling trump speech since this covert diagnosis unconscionable saying and i quote the longer donald trump is president the more reckless he seems to get. Thats your correspondent kind of like in washington thank you so much lets turn now to some of the other stories making news around the world the u. S. Senate has opened hearings into the confirmation of any kone barrett to the u. S. Supreme Court Republicans are rushing to fill the vacancy before next months election if confirmed buried would have would solid solidify the conservative tilt of americas highest court. This years nobel economics prize and with it nearly a 1000000. 00 has been awarded should 2 americans all know graham and Robert Wilson specialize in auction seery their work helps in trading everything from airport lending slots to buying and selling goods online. U. K. Prime minister Boris Johnson has unveiled a new 3 tiered system to come about rising coronavirus cases in the regions will be cast into one of 3 covert alert levels in liverpool pubs bars and most public facilities have shut down the u. K. Has europes highest endemic death toll. So far germany has fared better during the coronavirus pandemic than many of its european neighbors of the number of new hotspots across the country is on the rice especially urban areas thats from just a range of new restrictions which differ from state to state leaving lots of people uncertain about the. 2 weeks of fall vacations are in full swing for many people across germany but travel will be difficult this year especially for those living in the country socalled corona virus risk areas. Various areas have surpassed the threshold of 50 infections per 100000 residents over one week including german cities like berlin munich frankfurt and cologne. To try to stop the spread of the virus many german states have introduced travel restrictions for people who live in the risk areas in the states they cant stay in hotels or guest houses unless they show a negative covert 19 tests no older than 48 hours or quarantine for 14 days but other states havent imposed restrictions the picture is chaotic making it hard for people in germany to understand where they can travel to and under what conditions the federal government is the fending the measure but critics say the Domestic Travel restrictions wont help stop the pandemic and will put a strain on germanys testing system. Dicom addition burn is in my opinion not really a reasonable. Measure because most travelers are no really infectious so they are low risk and we waste a number of very important and very valuable p. C. R. Tests in order to make sure that. It is also very burdensome for the travelers and it is basically useless for controlling the pend makers in germany. The new restrictions have disrupted travel plans at a time when many families across the country normally go on vacation people are frustrated by the lack of clarity about them on the one hand i think its confusing for example i live in brandenburg and work in berlin and sometimes i wonder which rules apply where this always leads to some confusion and i would have liked more consistent rules i would prefer some uniform rules citizens would be more aware and maybe the rules would be communicated better. And if people understood the measures better maybe more would respect them. Now. German chancellor Angela Merkel will meet with state leaders on wednesday as criticism of the accommodation ban grows they will try to bring some order to the chaos. Did have used chief Political Correspondent millan next train sent us this update on how the government views the Current Situation in germany the government is worried the spokesman for the chancellor said today that the situation is very serious that the country is on the verge of were already in a 2nd wave and that germany is also seeing an increase in the number of severe cases requiring hospitalization and intensive care so he called this a decisive moment for germany. European Union Foreign ministers have agreed to drop sanctions on belarus in leader alex and the bloc is calling on him to halt the crackdown against protesters and hold talks to diffuse his countrys political crisis in recent days oh sorry shes have to change hundreds more demonstrators at a lot of retirees on monday officers fired flagons to disperse the crowds. That fractious the demonstrators chant as they confront belarus is feared right place in recent days means can saying its my serious confrontations in months protesting pensioners he offices with flowers usually approach her offices repeatedly use pepper spray on elderly demonstrate as. The older generation was once Alexander Lukashenko as bice now though many demonstrated a fed up with the regime. That im not afraid of stun guns into gas when mosques and goggles and everything will be fine for you carol they have now been over 2 months of protests in belarus with judges the government seems powerless to stop displays like basine said from minsk. But its trying in recent weeks Security Forces have again been intensifying their crackdown. And now the countrys hardline deputy interior minister is warning there might be even worse to come from Security Forces. When you were doing so i pledge we will maintain order in this country but if the situation demands that interior Ministry Officers and military service men might use right to control weapons firearms as we are told it is the situation in belarus to tear i did in brussels a Foreign Ministers met they deliberations focusing on how to get the right shame to negotiate with the opposition. With little sign about an hour they grade to prepare more sanctions on government officials including one president. How himself today ministers heard that mr lucas lacks any democratic that you didnt see and they sent a clear message to the bitter russian Authorities Say that business as usual is no longer possible. No hope in brussels targeting those responsible for the crackdown on peaceful protests who force the regime to the type the e. U. Wants to see more dialogue and less violence in minsk. And of that meeting in new Foreign Ministers also agreed to impose new sanctions against russia over the poisoning of russian opposition figure alexina via me a bloc will draw up a list of officials tolls responsible now on a fellow no aug and was airlifted to germany for medical treatment tests by a german lab later confirmed by the organization for the prohibition of chemical weapons found he was poisoned with military nerve agent novacek the russian government says it did not for years now found me. The oxytocin is dying thats a stern warning brought back by scientists who spent a year studying Climate Change in the region they made the journey aboard the german icebreaker the palash dan gathering valuable data about the ocean ice and atmosphere around the north pole. The last few yards of the most complex north pole expedition ever after a year in the arctic the German Research ship pull our stern is coming home a special moment for the woman in charge of the alfred figure institute. Do you see my tears of joy i am so happy that our ship is back home and when i saw it again after such a long time i thought we are so lucky that everyone has arrived home safely ok last fall the polar stand froze onto an ice floe and drifted across the arctic at a speed of about 12 kilometers a day propelled by the isis movement on ocean currents the crew came from 20 different nations and worked throughout the darkness of the arctic winter in temperatures that sunk as low as minus 40 degrees celsius one danger throughout the trip was hungry polar bears nonetheless they successfully gathered the information necessary to learn more about Climate Change. The experts on how the expedition paid off i am thoroughly satisfied with the results and with we have pushed the limits of Polar Research we returned with a treasure trove of data and samples from the arctic that will have a long term effect on science the expedition ran up a bill of 140000000 euros but its not over yet for the scientists who are on board it will take them years to analyze the data and samples that were collected on the polish town. Its one of the wonders of the world. And one man has managed to secure a private tour after a very long wait just a techie our mother arrived in peru in march and planned to spend just a few days to see the famous rooms but hes been stuck in the country for 7 months the site has been closed due to the pandemic grows government agree to let him see the pot before he returns to his native. Said it was an amazing experience. Youre watching news and heres a reminder of our top story at this hour u. S. President donald trump just back on the campaign trail interest supporters at a rally in florida the president s medical team says he has tested negative for growing up iris his democratic rival for the white house joe biden has also been painting he held a drive in rally in ohio. Youre watching dude i mean news coming out next hour dr phil and fine tuning the climates and you can always stay up to date with the latest news and information on our website at steve dot com or you can follow us on twitter on instagram at. Im using how much time takes to watch. Live. In mexico many push polls love us turn out in the world climb a tree Different Office door this is much less frequent for one week. How much worse can it really does. We still have time to our ongoing. Process. The planets are straining on to view the facts of Climate Change many researchers believe we have to intervene to prevent us from happening reached by so many people it might sound a bit like playing. Manipulating oceans seeding towers. Creating a sunshade for the ark all to solve these i just saw. Some of the ideas. You cant tackle something this scale this moving this fast. It just science modifying our climate is it hubris in iceland researchers have already turned Greenhouse Gases into stuff on there that you can see sort of rights and thats what this is to be injected into the i Love Reservoir thats the solution to definitely in my opinion this would be one reason. Why a large scale scientists want to interfere with the arts process and splash. Land 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 has lost track of the drive to protect their part but there are lots david keith of Harvard University as one of the most controversial climate researchers a 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 hold in Global Warming here by 1st big Pilot Project names copecks keeps being postponed and theres still not too much opposition. But it is is it something that might in combination with emissions cuts reduce the overall climate risk maybe substantially thats the evidence we have for climate calls so the question is to what extent the solar charger reduce climate rest actually harm people in the if art like extreme storms. Screen temperature Sea Level Rise those are Research Questions that we dont know the answer to. So cold sona radiation management is a gamble Little Research is being dom on the risks and yet it could be a lost life line when it comes to turbin Global Warming. In practice it would mean at least 10000 aircraft injecting destructors for every 2 years the planes would release sulfur particles as evenly as possible a town to dudes of molten 10 kilometers these particles would reflect one or 2 percent of the incoming some might. 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 northpoint 4 degrees. So much that you have to put in there well it depends how much solar generation 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 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 times its not technologically a lot of 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 non interference but the c o 2 is already in the atmosphere even if we cut emissions to 0 tomorrow its basically impossible but even if we cut emissions very quickly which we could do that doesnt make the climate problem go away and humanity. Its a long way from 0 emissions once we started pouring some fun 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. The technology skeptics. My biggest fear is that Climate Change will advance to the point where this planet can no longer sustain human life. To this true jan a few years that so no geo engineering will change weather and precipitation patterns damage the ozone layer and produce more ask the drying some studies show some interest for dru geo engineering is worse than 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 engineer whos already in the world so you cant stuff that. You cant stop the idea of do insuring from existing but but what you cant 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 even a modest solar geoengineering 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 has risks but not doing. While wearing creasing a aware of the affects of Climate Change we cant accurately predict the consequences of geo engineering. Were on our way to visit an environmental activist whos committed to strengthening natures own capacity for self. To know what my biggest fear is. Is that the history of the collapse of civilizations is really repetitive. And were seeing the tail end. 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 switzerland. The 1st was patagonia pock 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. At. The. Split the end of the world yeah 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 World 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 with just science it would wilson said we should give i think have you heard it. Didnt 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 i manage 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 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. That. 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 have done for the last 30 years say. They call this. The entry. And it is i am not interested. And believe that its. Where we were in gurlitz humans are in the new world and 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 climactic zones a chance. In davos a meteorologist is investigating another way of cooling they are. Adamant wasnt or one of my biggest fears about climate. Change is that the ocean supplies will become even more unequal droughts more floods and especially in terms of our droughts that theyll be moved climate refugees and more wars fought because of climate. Breaker low man thinks its possible to manipulate cloud formation in such a way that Global Temperatures fall the likeliest candidates seem to be cirrus clouds sos there is clouds have a greenhouse effect be 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. Sirus after when streaks of ice count 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 ones cool the un they should definitely stay but serious clowns have a woman of fact 94 when i snooped clear i am president and yan might when an airplanes turbines condensed 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 earth to escape so on balance the heaters are in order to cool the planet cirrus clouds would be prevented from forming like you cancer of the atmosphere could be seeded with desert danced for example the ice nuclei would grow faster become larger and fall to us as hail the radiation balance would change and the temperature would drop a little. Live for the whatevers have the advantage of such horrid dust would be that we know. 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 decision lies in v. M. S. Which bodies would decide which individual countries would do Something Like that. And good as all those months. And in any case who would benefit from it in order to answer that question 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 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 good so who wins out just given
