and by contributions to this pbs station from viewers like you. thank you. announcer: and now, "bbc world news". >> hello, this is "bbc news." i'm nancy with the headlines. a pill developed to treat severe coronavirus reports positive trial results. it could halve the chances of dying or being admitted to hospital. scientists say the scale of deforestation in noren brazil risked turning the amazon into something more like savannah. london's metropolitan police tries to regain the public's trust, and with just hours to go until the culmination of europe's first mission to mercury. we ask one of the officials
5:02 pm
involved what he hopes to find. ♪ hello and welcome. there could be a breakthrough in the way we treat covid-19. interim trials suggest that a new experimental drug for severe covid cuts the risk of hospitalization or depth b about half. if authorized by regulators, the new drug, which comes in the form of a pill, would be the first oral anti-viral medication for covid-19. our health expert has more. >> on the suffers these are very positive results. the way these trials work, you give half the people in the trial the pill and hatch a placebo. seven per vent of the people in the trial that had covid or had just had it ended up going in
5:03 pm
the hospital. in the placebo part it was twice that. that's where you get that positive result of cuts hospitalizations by half. also, when you look rat some other statistics, there were eight deaths in that placebo arm, zero deaths frommed group that had taken this pill so overall on the surface very, very positive news. since we started covering covid 18 months ago, that phrase game changer from scientists has been used again and again but the are imminent science, very positive about this results. dr. amounted any fauci, the top diseases expert in the united states gave his reaction. and, the news of the efficacy of this particular anti-viral is obviously very good news. the company, when they briefed us last night, had mentioned that they will be submitting their adapta to the f.d.a.
5:04 pm
imminently. the data are impressive. >> interesting what's happened here. the regulators and this independent solomon: terrific body in e states have told america, the drug -- merck, the drug company, you have to stop this trial. not because there was anything wrong but balls it was so poof. because you have hatch this group that didn't take the -- take the pill so eitherically, you can't do that. merck are going for this emergency use of authorization. saying they're going to go through it in the states within two weeks. fen then we have to wait for the f.d.a to approve it. it could be a matter of weeks or so before we start to see this being used. >> a study by researchers in brazil says says the scale of defos toews risks turning it into more savannah-like terrain.
5:05 pm
it could cause extreme heat in the country's north, threatening the least of nearly 12 million people. the amazon rain forest is the single lar els remaining tropical rain forest in the world and home to about three million species of plants and animals and about 1 million indigenous people whose leeches are being increasingly changed by deforestation and climate change. m talking to one of the authors behind the study. touch thank you very much for talking to us. tell us a little bit about how grave the threat to the am donell is that y found in the study. >> thank you. yes, i think now the study has revealed that in addition to global warming, which already presents a very serious risk to human health, if we exceed the
5:06 pm
air temperature of 35 degree it is celsius and 100% relative humidity, the air saturated. humorrings cannot -- 24 is the threshold. and in addition to global warning were you look at degradation of the forest, always means significant increasing temps and those two effects combined would really increase the risk to human health tremendously. in scenarios of very high emissions and of full degradation of the forest. we were talking about 50% of the days of the year, a few hours during the hot period of the day, people -- this threshold would be exceeded. it will be almost impossible to live in the am donell.
5:07 pm
>> and that would affect a lot of people, 12 million according to this study. can anything be done about this? >> well, certainly t most urgent is to -- issue is really to stop deforestation, to interrupt the use of fire. the amazon is becoming more and more vulnerable to human-induced land-eulls changes, including more vulnerable to fires. on the other hand, also, the amazon y countries, especially brazil, has to improve very much the health care services for people in the amazon. it's a very poor system today in the amazon and people are already going through a lot of suffering due to this very, very poor health care system. >> and just how seriously is the brazilian government taking this
5:08 pm
phlegm, bearing in mind that a lot of it is being caused by logging? >> well, we hope that this new scientific study that the global and scientific community is producing showing the risk that the amazon rain forest is going through, ifle really make the government of the am zone yan countriles, especiall the brazil yan government, to completely change their policies towards the am son. we are seeing a polls that encourages amazon deforestation, illegal mining and logging so we have really to put a full stop to this mode of development. >> thank you very much, doctor, for joining us. >> touch. >> red-hot lava from a volca erupting on the spanish island of la palma continues to flow into the stay, sending out vast

in the streets of milan. the march marks the end of the youth for climate meeting which took place in italy. the group showed their support for proposals to tackle global warming that were introduced at the summitt. the bill will be sent to the glass co-top 26 meeting in november. because that new u.n. climate summit in glass coe is only a month away, many are trying to slow the rate of global with warming but australia has been called of out for not doing enough. our correspondent has been to the valley, one of australia's mining hot beds to find out more. >> the devastatingh fires less than two years ago were the starkest -- starkest warning yet for australiaens. experiencing firsthand the consequences of a warming planet
5:19 pm
and the science is clear -- cutting carbon emissions is the best hope of slowing the palings of the rising temperatures causing these extreme weather events but australia's commitments fall well behind other rich countries. in june, the u.n. -- for its response to climate change. >> our goal is to help preferably by 2050, as soon as. >> in the hunters valley, it's the bed rock of the economy. despite pit the global urgency, climate change remains a devivi issue here in australia. it draws in the powerful fuel industry or the miners, when an anti-coal entry doesn't play well. >> it's been in my family for as long as i remember. dad has always gotten up early

anyone, renewables are growing fast in australia. the refinery inueensland is one of the country's biggest users of electricity. with more than a millionsome arm panels, it's generating about a quarter of its power from the sun and it aims to be 100% renewable energy as early as 2025. >> it is the right thing and also the smart thing to do. our customers are on an urgent path to decarbonize. >> even though it's on the front line of this environmental emergency, australia is out of step with allies when it comes to climate action, stuck in a balancing act between its domestic politics and its international reputation. "bbc news," the hunter valley. >> europe's first mission to mercury is expected to reach its destination in just over five
5:22 pm
hours' time. the space craft will flyy the planet at high speeds, taking picturings of the planet and sending them back to earth as it does. it's moving too fast to go into orbit but it will begin more detailed observations in four years' time. joining me is the european space agency's senior explorer and he'll be working with. first pictures coming from the probe. good to see you. must be pretty exciting waiting for the pictures. what are you expecting to see? >> well, the only cameras we have on board during this fly-by or webcams, small monitoring cameras practice, which are on board to help us see whether bits and pieces are deployed after unfortunately la. the main science camera is sandwiched between the two big space craft, which are in a stac of therethrough.
5:23 pm
they don't separate until we finally actually arrive at mercury at the end of 2025. so they will be taking plaque and white pictures, recommend thetively low technology. but we're lking forward to getting mercury science back. 24 is the first of six fully-byes so lots of work before 2025. but it's very exciting. these preparations and building for over 20 years. andwith launched it three years ago. going to be very exciting tonight. >> that's a long time coming be um what are the questions around mercury that are so fascinating and what are you trying to achieve from 24 many i guess so? >> mercury is the inner most planet in the solar system. it's roughly a third of the distance that we were from the such so it gets more hot. it's about 450 degrees send grade -- sent grade on the sun little bit side, the temperature
5:24 pm
of the inside of a pizza oven and that's a great challenge for a spacecraft to operate there. mercury has a verying from surface with some materials on it which should have been burned off billions of years ago and yet they're still there. mercury also has a very dense metal corps when -- which extends quite a lot further towards the suffers than our metal core here at earth does and we don't understand how mercury formed. was it hit by something else that stilled away much of the crust or something to do where it was born? and it has a magnetic field on the suffers, which is curious for a planet which is so small. earth does but mars doesn't. and it's one of the least visited planets in the inner solar system becau it's so hard to get to.
5:25 pm
>> can you explain why it's so hard to get to. we understand it's going to take years to get into a stable orbit position. why is that? >> if you want to go that long way from the sun, you need a lot of energy to get there but actually, you need a lot of energy if you're going close to thsun. and that's to slow down. if you just let the sun pull you in, you'd be going past mercury fast, you couldn't stop. we're using the pla. we've flown past by eah and venus and now we're getting ready to f by mercury. that will help us coast and get to the right speed by 2025 where then we can get into orbit close above the surface of mercury and start doing the southern. it's actually harder to get to mercury, en though it's close, than to polluteo. >> that's fascinating. will we see a landing on mercury at in i time?
5:26 pm
>> it's a whole other thing t land on the assumption because you have to slow down again and that means carrying a big, powerful rocket motor so not in mission. wee not going to be landing on the such as of mercury this time but who knows? we're following on the foot steps of mariner 10 and the messenger probe. the way science works is we expect to find other things we don't understand and maybe in the future, aened laker might be the right way to analysis nose questions. >> we look forward to seeing hose pictures. on and off. >> my pleasure. >> some pictures to share with you now from australia's north earn territories. a filming mission but this was being used to get footage of crociles when one of them decided to take a bite. in case you missed it, you can see it here again in slow motion. that looks quite nasty.
