they will start advancing on this well now behind me are thousands of. sumo exits to the square being below 0 so when they move forward it's going to be a bit of a scrum the hotels in the businesses have looked bad tools they've sucked up put up the sauces but a lot of the windows have been smashed and bear in mind that this is a weak area. of the protests and we're joined by thousands more peaceful demonstrators who said that while they had started a protest against those sentences handed down to the codependents cataloging those on monday they were now very concerned about the police brutality that they had seen on friday 20 suspended to protest with rubber bullets and tear gas engine 150 protesters 3 of me now in critical condition. still ahead on al-jazeera. a huge wave of support for one man why millions are flying the flag for argentina's

president. chile's government cracks down on protests or how the latest in santiago and what's going to demonstrate or so worked. hello there we've had one to 2 showers across areas of the middle east in the last few days and you can see some bits and pieces of cloud working their way eastwards and this is where indeed we have seen one or 2 showers now through sunday we still have the chance that you cross into the northern sections of iran but also across into turkey and at times we could see some heavy thunderstorms certainly by monday and those shows like had to work their way to the east was time which is not too bad 34 celsius across into baghdad and 23 across into kabul now further to the

south again temperatures here they have been coming down slowly the humidity has been improving slightly as well we're going to temperature of 30 in must pass on sunday and temperatures in the mid thirty's really for doha 35 as you can see there on monday and 35 across into to riyadh further to the south down into southern africa again we've had some shots to eastern areas of madagascar mostly dry sunday as you can see there but want to show is likely into cape town 22 so feeling a little bit cooler temperatures about the average for this time of year and then it's a fine warm day sunday into deb and then by monday we could certainly see wanted to showers that again we've got this fairly strong flow but staying very warm again for the next couple of days in johannesburg on monday a high of 33. the weather sponsored by katherine lanes.

right. like you know let's recap our top stories right now head of the lebanese christian forces party has announced his ministers from the coalition government the news the celebrated by thousands protesting for a 3rd night what a cool change. the u.k.

has asked the e.u. for a 3 month extension to parliament force prime minister boris johnson to send a letter seeking a delay after he lost a crucial vote he did not sign that letter but instead included and then another document saying an extension would be a mistake. spain's acting prime minister has dismissed catalog leaders call for dialogue dependent supporters are angry that 9 of their leaders have been imprisoned. turkey's president has vowed to press on with his offensive in northern syria and crush kurdish forces if they don't want to draw from a safe sound truce is largely holding despite both kurdish forces and turkey accusing each other of violations under a deal brokered with the us kurdish fighters have to leave an area 32 kilometers deep into syria were turkey wants to establish its so-called safe so russia typer to resume the offensive if the fighters don't withdraw by tuesday evening strafford asked more from. the turkey syria border volunteers in medics say that off to being

repeatedly denied access by turkish backed forces to the town of russell i knew they were eventually allowed in and able to evacuate some of the injured from the hospital the but also deliver made it cool. there have been sporadic clashes in the. sound the wider cease fire across the border area though does seem to be holding has been a statement made by the s.d.f. kurdish forces commander muslim abdi he's accusing turkey of scuppering this us brokered deal by not allowing kurdish fighters out of the city of russell and we've spoken to some of the syrian fighters in there and they say well they say the kurdish forces are refusing to leave their positions meanwhile president or the one who has has reiterated his threats that if those kurdish fighters do not leave the

proposed safety zone by the end of choose date nights then turkish military operations will resume place afraid around 150 students in northern nigeria where they were reportedly subjected to abuse the school and in a claim to be teaching the koran it's the 4th rescue operation in the past month bringing the total number of students frayed from religious schools to more than a 1000 the latest raids expected to increase pressure on the government to crack down on loosely regulated islamic schools. south sudan's opposition leader has returned to the country to meet with president salva kiir sides are expected to be discussing outstanding issues just less than a month before their deadline to form a transitional government it morgan has the latest from juba. opposition leader rex much power is in south sudan for his 3rd visit since these deal was signed between him and south sudan's leader salva kiir mayardit last year in sudan's capital sort of tune that the 2 sides are expected to meet to discuss a number of outstanding issues ahead of the formation of

a transitional unity government on november 12th and those issues include the number of states as well as security arrangements which the opposition leader says is vital to be completed ahead of his return to make him feel safe to come and found that transitional unity government in november. dr rick bashar is here based on an invitation from the president to meet the u.n. security council in members of the african union peace and security council in prison kiran rick michelle will also said i have the today or tomorrow to discuss issues related to the peace agreement and we confirm that the 2 sides are ready to talk and resolve all outstanding issues for the sake of stability in south sudan now this comes at a time when south sudan itself is mediating talks between sudan's transitional government and various groups the 2 sides have signed a roadmap to start negotiating after the official peace talks were launched here in the south sudanese capital juba on monday but they are yet to get to the core

issues of the negotiations which include humanitarian access political arrangements and security arrangements and this comes as the 2 sides say that they want to reach a peace deal before the end of the year for the prime minister who was appointed recently and who has pledged to make sure that peace is achieved within the 1st 6 months of the 39 month transitional period. as it takes main opposition party is rejecting the pulmonary results of tuesday's general election the results show the ruling party headed for a major victory european union observers are raising concerns about reports of ballot staffing at some polling stations and an election observer were shot and killed and others attacked. there is a millennial choose their next president on sunday after 14 years in office. a fight on his hands to get re-elected as predecessor as interim president is attracting support for condemning what he calls says dictatorial leadership.

i passed years elections were a walk in the park for evermore rallies livia's 1st indigenous president but this time around he's full of things wrong comfortably close. his campaign slogan is a secure future and his socialist policies have always managed to keep the economy growing one of the highest rates in latin america while still so cutting poverty through social programs and only look the way he says if reelected plans to keep on doing the young people of the wealthy one we would like to give 5 more years of experience to bolivia so that it continues to grow economically to finish a great project plans like construction of roads and airports. but for the 1st time in a while there's a credible challenger. the former journalist and prominent intellectual he's attacking his achilles heel he's questionable commitment to democracy. i was

13 years almost 14 and there's too much it's too much injustice too much corruption and too much authoritarianism that's leading his towards a dictatorship. it all started with morality his latest reelection bid after 3 terms in power he needed to change the constitution to run again. he called a referendum to let the people decide now really they said no then he did it anyway . then outraged many and although there are 8 opposition candidates mrs become the figurehead for the discontent but analysts say the former interim president bolivia's loss leader before morale is this if you policies of his own. it was that they feel that they were doing for him even though he hasn't done enough it's a protest vote not a convinced vote he doesn't have a political party he hasn't run a campaign if you show more character he wouldn't be 8 points down he'd be neck and neck and maybe even beating it will morales

a moralist does seem more vulnerable than ever before environmentalist say the recent violence which burnt down $5000000.00 hectares of forest helped along by his government's allowance of slash and burn. allegations of corruption who also tainted his movement to socialism party but so far there's only one favor ever morales is still the frontrunner here and that's because of his handling of the economy which has consistently grown and poverty which has been significantly cut that's why a lot of people still support him but they're all question marks about his approach to democracy itself and that's where his rivals are gaining ground. sunday's vote may not be enough to see moralise home at the latest polls are right this could be close enough to go to a 2nd round. john homan. huge crowds answer the call of argentinean president to gather in the capital saturday

he's hoping to defy opinion polls and win next week's election against presidential challenger alberto fernandez who beat him heavily in the primary vote in august chris about reports and. it was called the 1000000 march hundreds of thousands of people gathering in the center of one a scientist to sing yes we can. and show their support for argentina's precedent. that. i have terror if parent isn't comes back we are here to defend the republic because if the others come back they will destroy everything the others are opposition leader albert at the foot amend this and former president cristina fernandez a kershner from the peronist party. presidential elections are one week away and everything shows that what is called the fed and then this forum and this formula will wind up the show is going to be extremely difficult i mean when we are coming right back that even though it means the country and the can't be devaluation of

the currency and. by the way see if we get over it. was. in august the primary election results show that there was at least a 15 point difference between fundamentalists and machree some say the difference could be bigger next time but markey believes they can turn the results around january with more jobs we have seen their attitude in previous governments of rests with arrogance with the way they have of conceiving power that so many of his reject enough of that. came from venezuela 2 years ago he says he's afraid that if cristina kirchner comes back argentina will follow the steps of venezuela with a populist government that he says could become increasingly authoritarian we're going to go from there and i'm here to support argentina because this is a wonderful country and i don't want it to end up like us argentina is in the

middle of a new economic crisis and that's the main reason why. next week but on saturday there were millions who believed his still has a chance. a curfews come into effect in capital following protests about planned price rises for public transport president sebastian pinera has backed down on the increase fares but crowds are still out on the streets the decision provoked nearly 2 weeks of violent demonstrations and led to a state of emergency being called on friday soldiers continue to patrol the streets it is the 1st time the military has been deployed since the end of the augusta pinochet dictatorship in 1908 or haze of age or a man is a chilean social researcher from the university of cambridge a blames the government for not listening to protester concerns this should be a political dialogue this should be certain some sort of.

agreements table too to talk about of these 2 maybes to bag with the decision of pricing the 1st of the of the metro that cost all of this but actually that is just type of the iceberg many things will be defined in the events of this next 3 days or so because we have tanks in the streets we didn't see that in the last 30 years we have the military is in the streets so there might happen something really really damaging for the future of this conversations but the must be some compensation and there must be a process of learning from all the political class to understand that people cannot take it anymore because they're not a i mean the cons leap with this suit with these conditions and the us is looking for a new location to host next year she 7 summit president donald trump had planned to hold it at his call for a sword in florida but democrats and others accused him of misusing his office for personal gain the pushback crazed and irrational hostility he says officials had

began looking for a new side and suggested the presidential retreat at camp david as a possibility. oil spilled in the waters off brazil have washed up on beaches a popular tourist destination usually pristine santa porto de gaulle and us in a state has been marred by sticky wax sludge or oil as been contaminating the country's beaches for more than a month now brazil's environment minister as plain as whale afore the disaster they say but i said it's a real tragedy and another definition exists it is unbelievable the lack of help from the state and areas from the municipal to the state to the federal the amateurism which is unbelievable. a direct flight from new york to australia has touched down in sydney as part of quantas attempts to push the limits of correctional flight the dreamliner aircraft to 19 hours and 15 minutes to reach sydney it carry 50 people who are brain monitoring equipment to see how their bodies cope with the extended time in the air on to us is hoping to began flying

being new york to sitting around martially by 2022 once that happens it will be the world's longest commercial passenger air service enter thomas has more from the airport where the plane touched down in sydney. the whomping of a longer one off flights in the past but if this is from new york city and back becomes a regular shared field service well that would make it the world's longest passenger flight on this flights the 2 passengers that the well to business they will have paid so no one had to experience being stuck in the middle of an economy row for almost 20 hours nevertheless the airline quantas carried out experiments on but the passengers and the crew measuring their levels of metal total and for example to see whether they were getting sleepy in flight seeing whether different food at different stages in the flight kept people awake when they wanted them to be awake help them sleep when they want them to state the passengers that i spoke to said it was a very comfortable flight for them with 50 passengers on board only and the ability to walk around the whole of the plane it wasn't exactly representative of what

a real flight would be once the airline wants to get they service up and running by about 20202023 but that is subject to a few things not least regulatory approval for a flight of this length they've also got to do a new deal with their pilots pilots are very skeptical about working on such a long flight and they need to negotiate with the union to get that through and then of course the economics of them have to stock up primarily though this is probably be a flight to business people travelling between sydney and new york need to get their boss because in the great scheme of things citing 3 hours 3 and a half hours perhaps on the current services still 3 los angeles or houston at the moment well they'll be a premium in terms of pay. so that's a no everybody will want to play. and we shall carry these are the headlines right now on al-jazeera for ministers and lebanon's coalition government are set to resign adding to the turmoil on the

streets ahead of the lebanese christian forces party samir jaja said he did not believe the current government could push through economic reforms in the news was celebrated by thousands of protesters who want the entire government to quit the u.k. is asked the e.u. for a 3 month extension to approximate parliament force prime minister boris johnson to send a letter seeking a delay after he lost a crucial vote he did not actually signed that letter and instead sent another document saying an extension would be a mistake spain's acting prime minister has dismissed cattle on leaders call for dialogue are independent supporters are angry that 9 of their leaders have been imprisoned. turkey's president has vowed to your press on with this offensive in northern syria and crush as he says kurdish forces if they don't withdraw from a proposed safe zone the truce is largely holding despite both the kurdish forces and turkey accusing each other of violations under a deal brokered with the u.s. kurdish fighters have to leave an area 32 kilometers deep into syria or turkey

bottles of stewart living in the presence of who you know visions of the mother to walk into the city that they're supposed to. this is techno a show about innovations that can change lives the science of fighting wildfires we're going to explore the intersection of hardware and humanity and we're doing it the unique way. this is a show about science. are known by scientists. tonight like. techno in search of the great american prairie where in the current state yeah ironically we have such little of it left farming and over development killed it now get ready for this explosion of color and the return of these native animals how many plant species do you have in here but fall into years trying to bring back one of the planet's most complex ecosystems ran outta trouble

we just needed something that help to level the playing field why a certain animal from america's past was needed to pull off the impossible we've just arrived to furniture so grassland and. i'm seeing these bison for the 1st time rita davison is an environmental biologist tonight a trip to the heartland always a baby. dearest santa maria is a neuroscientist i'm phil torres i'm an entomologist the epic drought of 2015 takes a hidden toll. from above these trees may look green and healthy they're not here we see something that's dramatically different now the technology that can see what we can't. that's our team i'm a prairie fire weather now let's do some sun. hey guys welcome to techno i'm phil tours joined by kara santa maria maria to

davison and say we're going to talk to environmental stories and to start off the great american prairie to me it's one of those iconic images of how the us used to be unfortunately now it's almost entirely just a part of our history yeah there's been a lot of over development of farming and a suburban explosion that's really taken a toll on a lot of prayer ecosystems illinois has been extremely hard hit it's changing but there's been a big change in the landscape there yet this is happening across the united states but i got to say what i really love about this story is that there's a bit of us west so there is i want to give anything away so let's go about 90 miles outside of chicago where they're bringing back a little piece of history it's kind of a big piece of history ok a big piece of history to go on. you're looking at a $3500.00 acre experiment in

a growing field is known as restoration ecology. this is the new choose the grasslands preserve in franklin grove illinois 90 miles west of chicago where the nature conservancy is rolling back time 200 years to restore a tall grass prairie that was almost extinct. were in the curry state yeah ironically we have such little of it left at the time of european settlement about 2 thirds of the state some 2025 1000000 acres in the state was tall grass prairie we have less than 1100th of one percent of the native prairie that still intact. the mission is being overseen by 3 illinois and natives just walk director of science for the nature conservancy project director bill kleiman. and restoration ecologist cody considine. it was a vast landscape dominated by those grasses but the real diversity of the prairie

was in the wild flowers the forms the broadly plants and thousands of species of insects and dozens of birds and mammals and reptiles called the prairie home along with animals like the bison. what was once this bass landscape across much of illinois has been virtually eliminated and turned into the corn belt. but illinois isn't alone since the late 1900 sprit grasslands across the united states have been steadily vanishing. i've heard grasslands and general referred to as the unheralded counterparts of the rain forest and grasslands have a critical role in terms of climate change as well in a prairie most of that carbon is stored in the soil and so it's very secure for very long term storage a soil organic matter in essence the plants of the tall grass prarie absorb carbon dioxide trapping it in their deep roots. the restoration began in 1906 growing from

a small plot of remnant prairie land that had never been farmed. and starting with fire the process hasn't changed much in 30 years. it's completely fire dependent without fire we could not have pretty the vegetation grows more vigorously and most species of plants have a season of more intense blooming right after a few to the 1st year the 2nd year after a fire no one knows that transition better than restoration ecologist cody considine. gray we're standing in what looks to me at least 2 very different types of areas what happened here so yes or right in the line of 2 different prairie restorations the one right here was planted 2 years ago and the one behind us was planted a 3 years ago so overseeing is as easy prey restorations. get older more plants emerge as they get more mature they're flooring so they're quite dynamic how many plant species do you have in here for this particular flight and i believe we had

130 species ranging from there's a native western sunflower this is a coral species we have rattlesnake master here we have grassley of goldenrod here isn't a neck in a show here a paper book on foot already flour. all those bloomers started here all right so this is the seed room. project director bill kleiman well you might think that the prairie stude would find its way out into these former corn fields but it doesn't walk very fast so we would have to wait millennia whereas we can collect the seed from the remnant prairie of bring it out to a cornfield that we're retiring planted and it'll grow back year do you have a sense of how many seeds you in the volunteers here have planted over the years about $250.00 species a year so it's it's millions and millions of sea. conventional wisdom was to

plant 10 pounds of seeds breaker but bill ordered 50 pounds and the fields blossomed none of that would be possible without a core of volunteers like jay stacey. so what are you cutting today this particular for is called per coreopsis scientific name coreopsis pomade how long have you been doing this i've been doing this is my 21st year. i'm a prairie bar where. all the tall grass planting was a little too successful. we just needed something that help to level the playing field. what they needed was something to thin out the grass. like an enormous vacuum this. lucian not a dyson but a herd of bison. a posse of 800 pound grazing machines.

we've just arrived at the new tusa grassland and i'm seeing these bison for the 1st time and i feel like i've just been transported back 15200 years it's it's pretty it's pretty remarkable to see these enormous animals that were almost wiped out from north america oh there's a baby there's a little one 0 a couple of. bison have been part of the vision for the project since the very beginning but it's taken us close to 30 years to be able to put together enough of a landscape where it was a practical consideration for us. to . these iconic bison were the missing link for a massive restoration of this endangered tall grass prairie run by the nature conservancy. would you say that they have been

a game changing factor here. as these animals are going to make a difference on this prairie and. i hitched a ride with misuse of project director bill kleiman and restoration ecologist cody considine to track down the bison in their $500.00 acre grazing area. the wire the bison so important to the restoration process bison 8 grass and there the disturbances they're creating puts diversity on the landscape as they graze the nutrients are going in one of them is coming out the back and they are getting a very quick nutrient cycling on the prairie. those bison patties are spreading seeds and fertilizing the soil what's the average weight of a full size bison the coyotes can range from 800 to 1100 pounds in the bowls as they mature they can get up to 2000 pounds massive so how many bison do we have

on them on the reserve 30 adults and 16 calves the calf was just born last week a little tiny want to get easily pick it up it's pretty exciting to think about the calf being born a illinois prairie that hasn't happened for probably 200 years. what happened to bison here there was a tremendous slaughter of bison in the 870880 s. . just walk is the chief scientist for the illinois chapter of the nature conservancy. as estimated by the turn of the 1000s there were probably 402-1000 animals that had persisted out of that massive herd of 30 to 60000000 is close to extinction is absolutely closely extinction there was definitely a market for the hides for the meats also part of it is that it was encouraged by the u.s. government as a strategy to help reduce the food supply for the native americans in the conflict with the native american peoples it's estimated there are about 400000 bison now in

north america. but most of those mice and we're bred with cattle for meat production only about $20000.00 are pure american bison. that genetic line dates back to 913 when 14 bison from the bronx zoo were trucked to win national park in south dakota at the behest of teddy roosevelt. so when it was time to bring bison to choose they looked for a posse with the wind lineage. we went to broken grassland another nature conservancy preserve in northwest. when i was in the october 24th team and brought back $28.00 holes with us we were essentially separated off the animals that we were going to bring back to illinois make sure that they were out a clean bill of health. 7

of the females we strapped g.p.s. collars onto so that we can get near real time movements of the animals tracking those movements with the g.p.s. collars is julio brockman a bison researcher at southern illinois university. what kind of data are you receiving so we're getting location information a g.p.s. point on a map every hour 24 hours a day so can you show me what you've been seeing sure these are the bison locations for yesterday they seem to be spending a lot of time along their corral and trap pressure and i can corroborate that because we were there and we saw them there so what would you say is the ultimate goal of your study having an amount of data really changes how we look at their movements and their selection it helps to understand what type of habitat they're like for reintroduction in the future. among the 2 dozen scientists doing research at the tusa is dr holly jones

a conservation biologist at northern illinois university with her team she's traveling in tagging small mammals to assess the impact of the big bison. the completely restoration ecologist playground i get so excited about this field of sand on one of them and. there it is small mammals are food for aerial predators things like hock things like owls and so it's really important to know how they're doing to be able to say how the person doing as a whole and that's because if the small mammals are tasty enough to become good prey they're feasting on a healthy environment of insects and plants. what do you see since bison have been introduced we've had. 13 lying around the world which was very surprising the line of evidence is pointing towards a shift in community compositions and there are different plots of land that have been restored at different times and all the way back to 20 years ago we can look at a plot of land like this that was restored 4 years ago and we're going to part of land

over there that was restored 6 years ago and one sees and look at how restoration progresses. how we become for science and some way. you can do you can go there. less than a year since the bisons arrival the environmental impact is subtle some changes to plant growth and small animal populations but the biggest change may be on humans. for a very connected to this herd they still feel like these are their buddies this is such a cool thing that we've returned this iconic mammal to illinois it's exciting. i got to say i love when you guys bring stuff back from the field especially from someplace as iconic as tall grass person read it what did you bring us at 1st till you got to stand up ok how tall you are about 6 to ok so here is

a tall grass from the tall grass player that is some tall grass stalk i mean i was literally swimming in this stuff you know this is amazing this is part of the vegetation we're taught in this is what the bison munch on this is that's exactly what they munch on this is what the bison were brought in to help control the kids . now these are little seed pods they look like musical instruments but they're seed pods of some of the vegetation on the prairie got a nice little ring to like it and this is what they've been using to replant some of the native vegetation and then when this is the last piece of the puzzle this is a bison ferment any way. that surprisingly soft yet and. i can see there's stuff in there arrows a lot of stuff in here so you can see really easily how bison would be dispersing you know these these little seed these large sea disperses across the prairie a word does even come a shape like a bicycle when i was looking at that footage i was blown away by the color in the

prairie the biodiversity the flowering plants and i wonder if a lot of people have that preconceived notion that nothing grows that they would if i told you kara that along with tropical rainforests prairie lands and other grasslands are the most biodiverse complex ecosystems in the world would you believe me. i mean i believe you because you are an expert it's right it's it's totally true but it does hold my mind and i thought it was really interesting to learn how important the prairie land is here in america for you know this because language change problem that we're all facing these these grasses and these different plants actually act as a kind of a carbon sink don't they they really do the bulk of the plants in the prairie are not above ground they're underground because that's how they survive fire they actually are a big factor in storing carbon yeah and that really does feed into the very next story read until you guys tag team do a little verify both from this guy and from the ground you know i got to see

california forests from an airplane like no other and while you were in your flying laboratory i was on the ground seeing the reality of trees and what's taken him down. this drought is so epic it's so out of the norm. that we actually don't have the answer to what can we expect long term california's epic drought. reservoirs are near empty farmers herding and it's forests are flame are under attack by opportunistic coasts so we're seeing tree mortality all over the landscape but in order to understand these changes to forests scientists must 1st assess their health. using field officers and airplanes we have the most advanced airborne remote sensing package that i know of on earth today for over a decade ecologist greg as never has been monitoring the health of forests around

the world in an aircraft called the carnegie airborne observatory tecno profiled his work mapping the amazon in a previous episode this time we joined him on his latest effort to map drought plagued california forests in his tricked out door need to 28. in the back of the aircraft are unique sensors designed to take measurements of the forest canopy while the plane flies over it we're flying over about $8000000.00 trees per hour one of these instruments is known as light our this instrument is a laser system that fires 2 lasers out of the bottom of the plane in a pattern that image is the forest canopy over it ever it is that we fly over in 3 d. what the instruments do is provide us a very accurate very unique way of understanding the amount of carbon stored in california's forests if you don't put carbon in forests then it ends up in the atmosphere and that contributes to climate change the plane is also equipped with a pair of spectrometers used to detect the chemical composition of trees it was

time for takeoff where we going today today we're heading out pretty close to the oregon border where we have a lot of forest that's unknown in terms of its drought stress and with that we were off from the air we could see reservoirs and rivers clearly depleted of water like shasta reservoir that's right it's a lot of water policy what you see of a pro but the forest canopy actually looks pretty green but they could look like they're pretty good sheep of california as forests are drought stressed today by losses about oh so these forests are in trouble back at the lab as there's team got to work analyzing all the data. that's where tech news phil torres picks up the story say you did a flight with merida these are the results and looking at the cockpit it looked green but here we see something that's to radically different and what you see we see that the forest is varies from what we would consider pretty average conditions

in the yellows and blues up there down to areas that looks severely drought stricken in red next we looked at an area where the drought stress was more acute so this is from los padres national forest this is what it looks like when you fly over gray green looks like your typical southern cal forest. this is what it looks like in chemical detail those trees are doing ok but everything else that is showing severe drought stress and that's showing here in red now that we have the view from above we decided to head out for a boots on the ground perspective i'm standing here in the middle of los padres national forest and as you could tell from all the dead trees behind me there's plenty of evidence of the impact of a multi-year drought one of the biggest problems here a bug that attacks water stressed pine trees. and now we're talkin all those a bunch of tom coleman is an entomologist with the u.s.

forest service a lot of dead trees right here yeah this is a nice will active spot for you to. bark beetles kill more trees than any other kind of insect or disease in north america when you just look across the landscape and you see this kind of patchwork of dead trees mortality is quite dramatic this tree here is full of thousands of bark beetles does that mean that all the trees around here are now susceptible right now from what i've seen it's just basically across the entire landscape have you ever seen this but not here in california. so just 10 minutes where we're looking at the devastation caused by the pine beetles and now we're here and you can see the damage done by forest fires and there's a lot going on here so even though the wildfire is actually gone through an area and cause major mortality it will still see bark beetles coming in afterwards

scientists studying our forest are concerned about the impacts from drought not just in california but also around the world now what we're starting to worry about is whether these droughts are somehow all interrelated in length at a global scale to suit a lot of force of the world or in trouble droughts putting pressure we don't know exactly how much of the global forest cover is at risk but where in the process now of finally getting the measurements we need to make those predictions. the scientists that are studying these things they can say here's the problem but their hands are tied they all they can do is wait for the drought to be over for only you know to pass and try to influence management and policy they need to get the data into the right hands i think that's the plan that has to get into the hands of managers and decision makers so that they can actually implement changes and whether we're talking about managing america's grasslands or america's force

and one thing is for certain that if we have healthy ecosystems we will eventually have a healthier climate absolutely and thank you for the story today guys know from prairie being restored by bison to forest being decimated by beetles one thing's for sure it's a complex ecosystem out there but there's a lot of scientists working hard on it that's it for now we'll see you next on your own techno dive deep into these stories and go behind the scenes at al-jazeera dot com slash techno follow our expert contributors on twitter facebook instagram google plus and more. hello there some heavy rain across the southeast of the united states all tied to tropical storm ernesto this is it but it's moving quite swiftly across the

southeast where the main weather is over the next couple of days but if you can see by sunday it really does pick up a pace and actually eventually it will push out into the west of the atlantic so just getting off the coast of the eastern seaboard so it will produce more rain some heavy at times across this particular portion macare not quite nasty in the southeast in the meantime the threat of heavy rain and tornadoes and very strong winds at about 60 kilometers an hour out towards the west that's where we got the the snow piling into the rockies and then by monday as it works its way east and actually feeds into this much warmer as the temperatures of course still a little bit cooler but even so the clash of that cold air and the woman to the east doesn't mean because he's in severe thunderstorm right the way along this line of rain right there down there into southern areas of texas and certainly plenty of scattered thunderstorms across areas of the caribbean and central america some fairly heavy. up towards nicaragua not a bad day sunday across much of guatemala the yucatan peninsula but plenty of rain

up against the political leadership that is clinging on to power and they have used force to do that. day 3 of protests lebanon's army and security forces are being accused of heavy handed tactics which are further inferior rating demonstrators they haven't left the streets despite the crackdown and arrests their demands remain the same i'm sorry. the government should resign and early elections must follow the response from the ruling alliance what's clear one act play out well now that we don't want the government to resign if it does it will take one or 2 years to form a new government and the economic crisis will worsen any will be made up of the same political forces.

but that is what protesters don't want they want change tension has been building for months these are difficult economic times and they blame those who have been in power for decades for corruption and the mismanagement. many here are unemployed some can't pay their children's school tuition fees others can't buy medicine or pay for their hospital bills the defiance is palpable people are behind us out if you think we are all gathered as live any from old age and from order we're saying one word week i'm not any more accept you. as giving them support is supporting the last miles not the government has no more yesterday president how do you decide we have 72 hours the 72 hours i'm not going to change anything the plans to impose more taxes triggered the protest prime minister sato how d.d. on friday gave his political partner 72 hours to come up with alternative sources

a professor of international relations at the university of waterloo and canada she says the lebanese government doesn't have a lot of options to try to address protesters demands. well it's really stuck in a very difficult spot because you know the essence of this challenge is frankly economic and i think the stock speaks for itself the fact that levanon is the 3rd most indebted country in the world 10450 percent of the g.d.p. it is really pretty incredible and not from mismanagement inefficiency an enormous mother corruption at the very often you know it doesn't help that you have then this is what stops tax and it's not just the past of course the high taxes nigh is the dots that you asked for $0.20 on a phone call just really broke the camel's back with you and i think comes of this 3 new very nationalistic tone which is very refreshing for lebanon because of course in previous times when mass demonstrations a half

i'm french so we have. you know off to 50 years i'm where i don't raise my children have paid my taxes i do voluntary work and i'm treated like a 2nd class citizen for a deal but it's been a right to the economy and the future of my children we have set up a. good. but m.p.'s didn't reject boris johnson's deal and they haven't given the country a sunken referendum. well they have done his paws and amendments which requires boris johnson to request a break sit deadline extension of 3 month he was to the right $322.00 the news to the left 306 so the eyes have it the eyes have it on lot. and he breaks it demonstrates his it's taking this is a battle victory though even if they fear they are losing the war. well the many thousands of people who have marched in london on saturday know that what paul
