it's a lot. since it started spraying crop production has increased by 10 percent. the quicker the process can turn a profit the more likely it is to spread round the world. even in frosty switzerland there's a real sense of urgency about limiting global warming. i came here for the mountains to climb to ski and in the alps you could see very early signs of climate change and of course closures are disappearing like we want to stop that if with and without climate change but the speed of disappearance is shocking. patrick hofstetter from the world wildlife fund took us out to see the disappearing place in. the alps

a bore me more than twice as fast as the rest of europe over some of it was our president to drown. yeah that's really special for us to farmers don't know to see to asia yet. their grass stopped growing stage there is a shortage. they actually started to slaughter their cows much earlier. after does so really dry summer i can feel a renewed sense of urgency especially also because the farmers are now going to really accept that they are directly affected by. 3 hours from superrich we come to what used to be the start of the giant mortar rochdale i see a. little used to be thought a lot of traffic. 150 years ago a place that came up creating it. all the way to. all the way to the station near.

me since then it's retreated by 3 kilometers the other with factories and 600 meters of that in just the past decade. i mean they're building this ancient place here is expected to disappear entirely with another lifetime. so are all the places in switzerland pursued protections shared by end of the century most of them build disappear completely on the few will remain in the very top mountains. the changing climate is already pushing the connally. many ski fields are now bare until after christmas. this is the situation we face in the last 10 years since i got laid translator they have to do a lot of establishing to prepare or drive down here or slopes.

even at higher altitude ski resorts are laying giant insulation sheets out of places to preserve snow. from may to october more or less they cover it like that and they remove it in october and start to ski again. they covering glaciers with blankets trying to stop the building while it's actually just slowing down the process so it's not a solution it's. to fight the symptoms of climate change. we have been doing to engineering now for many many decades in actually burning so much fossil fuel and altering the climate by humankind that we have to look now in a similar scaling to solutions to that problem. goes higher as we are here some believe the real added out to climate change is twin.

kilometers up there at our next stop women scientists who don't want to put blankets on places they want to blanket the atmosphere. in the hallowed halls of harvard university researches i'm looking at just how practical and dangerous geo engineering they say here we have one of the big pieces of test equipment that we use to work in preparation for putting instruments into the stratosphere engineering professor frank is preparing for the 1st test mission later this year. ok and so when put instruments into the vacuum tank and then we can simulate the stratospheric pressure so you have a 20 kilometers. belt use a high altitude balloon to scatter the sun reflecting inner cells across the upper atmosphere. right now they're fine tuning equipment to measure the effect.

without the spice race in a way it does on a much smaller scale. they fly up into the stratosphere high above us the white board theory is that tons of tiny sulfur particles delivered by specially modified planes would lower the earth's temperature would result in cooling the planet. it's what happened naturally in 991 after the philippines mount pinatubo but i know . and this gas then reacts in the stratosphere with accidents and turns into a soft you're right acid for the few years after mount pinatubo the temperature was noticeably lower and it cooled down the planet that was one effect that he got from what degree was it you know it's probably the range of about half a degree celsius. truck. is

a quick fix like that could have no side effects and what was also apparent after mount pinatubo and other volcanic eruption is that these particles in the end reduce the amount of ozone in the stratosphere so you know we've been trying to do a lot to actually fix the boat on land and here you now have the idea of introducing something that could destroy it again. and it's not just those risks the bank this project controversial it's the fear held by many of the scientists themselves but just the suggestion of a magic bullet gives governments an excuse to keep pumping up a missions. so good you've been running the numbers on this i mean is it economically feasible part of the problem is just how much cheaper these geoengineering would be than switching to a new city if anything is to chief economist journo wagner is the project's executive director it's so cheap that we're talking about single digit billions of

dollars to potentially influence entire planet's climate and now if i was running a fossil fuel corporation everything great this can solve the problem and we can keep digging up coal and frankly that's the problem right so i guess you might consider that the vested interest not in fact be very interested in something like this as you know yet another excuse not to cut c 2 emissions. very often compare stratospheric ginger into painkillers this does not fix the problem right it does nothing about c o 2 1st of all. we're just reducing symptoms and then human nature can kick in and say well you know it's hard to deal with changing the energy infrastructure which is very true it's a huge problem so in the end any decision will always have to be based on imperfect knowledge do you ever feel like this is playing god. it is there's a huge amount of hubris in this idea of saying wow oh we've caused

a problem let's fix the problem and i know how to do this we're going to do this and we know exactly what's going to happen to the whole planet yes and it has a lot of that is actually quite unsettling and quite frankly makes me quite anxious these can provide us possibilities whatever geoengineering can achieve the i.p.c.c. says the most carbon intensive fuel should still be phased out by 2050 at our next stop we'll see how the industry is fighting back because the jews it's a mission to keep this. goose it is a city built on. mining fossil fuels is as much a part of texan culture as raising cattle or roots good. but these days big energy is trying to sidestep demands to cut production. its

response is a much touted technology to cut the carbon footprint. for today we're heading out to texas is the biggest pal play it safe in the earth what the industry likes to call playing call. this is patron no. it's a coal fired generation with a $1000000000.00 absorption into our unit a that last that after the cold is fearne be a missions of pumps through it and soul that collects much of the c o 2 before it hits the atmosphere. it's early days to get excited. the tower captures carbon from just one of the complexes in generating units. what's more it doesn't actually reduce emissions over roll. the captured carbon is

pumped in liquid form enjoy the oil field. they put c o 2 in the oil fields and then you get more oil right as company spokesman david knox explains it breaks up stuff and deposits so they can extract more oil the c o 2 has a tendency it bonds with oil and when it launched it makes it slippery and when it's slippery or it comes off of the rock that last bit of oil in there but if you capturing c o 2 but to get more oil to actually increasing the amount of c o 2 overall it was if we were increasing the amount of oil that's being used but we don't actually have any impact on the amount of oil it's been used the oil is the same amount being used we're just increasing the domestic production and we don't have to import as much oil from foreign countries. the industry is looking at other options like superheating call that still produces

and they shouldn't without. well still since. this unit the small one in canada are the only ones in cold blood plants using carbon capture the personally. there is such a thing as clean coal but it is only that these 2 use. the economics are very challenging when will there be another one bill i'm not good at predicting the future but we now know that we can build one on time on budget. the uncertainty hasn't stopped politicians insisting the industry is saying. we have and the war on beautiful will lean coal. even. some time consultant to begin it is skeptical clean coal has been a mirage for very many years it would be wonderful if you could actually have all the benefits of the cheapest fossil fuel and cut the carbon emissions but it turns

out it's fairly expensive to do on the on the coal fired power plant that is actually takes out some of the energy that you would otherwise produce so it has real cost and of course you also have to store it securely and there's been a lots of conversations about that we've not really seen it running and we certainly haven't seen it running cheaply so again it's one of the things that we should investigate but we're not ready to do it any time soon. back in copenhagen ordinary citizens continue to do their bit for the. doctor alone boil down to his competitor it's whatever except the real cost of abandoning fossil fuel. most people are not content to only be able to charge their phones or have have their t.v.'s running or indeed their operating theatres and in hospitals running when the sun is shining and when the sun is not shining the cost from solar panels is infinite and likewise with that with wind turbines when the

wind is. why. it's not true this idea that when the sun's not shining the wind's not blowing we're not getting that energy because when the sun is shining in the wind is blowing you can charge batteries and so the frontier is battery technology . no matter how fast the world switches to renewable energy the age of untested high risk of geo engineering could soon be a promise. we don't get there by going you're trolling for better or for worse geo engineering is part of the mix going forward because we cannot get to where we need to be by conservation alone. it could be the last throw of the dice to say the planet after decades of governments ignoring dial warnings simply going green may not be galley fire and police.

president donald trump on thursday called on china to get involved what happened this giant is just about as bad as what happened with. you phrase the unconventional request to beijing comes as trump faces questions over his administration's request to foreign governments to help investigate former u.s. vice president joe biden his potential democratic rival in next year's presidential contest. trump was chinese authorities and other countries to investigate biden's son hunter and his business dealings overseas members of the u.s. congress are investigating allegations trump abuse just presidential powers in a july phone call with ukrainian president vladimir selenski we need real support in a trunk calls for an investigation into the bidens which is now the foundation of an impeachment inquiry led by democratic lawmakers on capitol hill 3 committees in the

house of representatives on thursday question former u.s. special envoy kurt volker about his orders from trump regarding a meeting in kiev just one day after trump's infamous july phone call with ukraine's leader bowker's name is mentioned in the complaint provided to congress by an anonymous whistleblower house speaker nancy pelosi says the impeachment inquiry is investigating whether trump implied he would withhold military aid to ukraine unless an investigation was launched against there is a quid pro quo if you're if you are already a couple days apart and granting or withholding and then asking for a favor to create dirt on your political opponent but trump maintains there was nothing nefarious about his phone call with the ukrainian president the whistleblower never says it was a conversation he got is it the vice of i just said that the surge has the road suffering the result of the former vice president argued there's no evidence that

he or his son committed any wrongdoing. there are no true george. every independent news organization. charges. has found. when i was still the number of trumpet ministration officials ensnared in the impeachment inquiry continues to broaden vice president mike pence is now in the spotlight after reports the president tried to involve parents in efforts to pressure the ukrainian leader kimberley health at al-jazeera the white house and trump has taken to twitter saying as the president of the united states i have an absolute right perhaps even a duty to investigate or have investigated corruption and that would include asking all suggesting other countries to help us out and fishes more from washington d.c. . donald trump has been tweeting out saying that he has the absolute power to

investigate corruption and he can ask other countries to help the problem of course arises when he asks them to investigate political rivals he was standing in front of the white house when he asked china to investigate joe biden and his son hunter biden saying they'd been involved in corrupt deals in that country all the offering no concrete evidence of why he was saying that and it came just a few seconds after he was saying that he has a lot of options with china referring to the trade talks that are coming up very soon in fact the chinese delegation will be in washington next week and democrats are worried that donald trump will sit down around the table and say well if you launch an investigation into joe biden i can start bringing tariffs don't know all of this comes against the backdrop of course of the allegation that he tried to put pressure on ukraine to investigate joran hunter biden you remember that during that call in july the president of ukraine wanted to buy more javelin missiles from the

united states and donald trump turned around and said well i want you to do as a favor democrats say that's a quid pro quo and it was that phone call that essentially set up the impeachment inquiry that we're seeing right now but those missiles have no been approved for sale to the ukraine it's gone through congress the state department has given its approval and the pentagon has as well that was separate to the year that donald trump was alleged to have put on hold while he tried to put pressure on the ukrainians but you can see this is becoming a big washington mess and all roads at the moment lead back to that impeachment inquiry. the poorest families in iraq could soon be given a basic wage addressing the nation on t.v. the prime minister abdul mahdi announced the government will vote on the new law following days of violent protests and women you know other than today we have to 1st return life to normal in all provinces and respect the rule of law under which

everyone lives in safety and stability i'd like to assure you that the security procedures we undertook which included blocking roaming data temporarily was a difficult decision however it is like bitter medicine it was mandatory because we cannot afford to lose your security or take risks or to leave your safety and the country in the wind preserving security is regarded as the highest in this country's interest and nationally is a priority well in our dramas have been driven by several factors a chronic lack of basic services like electricity and water only 8 percent of the budget for this year has been allocated to education reconstruction and health care that's compared to 14 percent on oil and 20 percent on security 13 percent of all adults in iraq are unemployed including more than a quarter young people of working age demonstrations have spread across several provinces most of the deaths have been in southern iraq and cities like macedonia

here to call for our rights. number of dead has risen steadily and over a 1000 have been injured since the defeat of ice or protest to say nothing has changed them despite the promises of politicians not just what yellow they are even with the curfew i swear to god we will not retreat we're demanding a simplest rights the simplest rights to be honest for you know what we separate ourselves for our country to be sacrificed for iraq people come out not for yourselves but for your children. iraqis are also unhappy with the abrupt dismissal of. the counterterrorism forces in the fight against i sold out and i say the government's reaction to the protests is a dangerous escalation iraq's fragile security relies on managing deep sectarian fault lines as well as a threat from the remnants of isolate ourselves and bug just the start of the
