with one tweet the u.s. president east caescalates his trade war with china. more on that. and the g7 summit, mr. trump reportedly questioning why he een needs to attend at all as world leaders make that i way to france. we have detailed analysis of what to expect. also ahead, the amazon wildfires, the change in tone from brazil's president now calling in the country's military to fight the fires. live from cnn world headquarters in atlanta, we want to welcome

our viewers here in the united states and around the world. i'm george howell, "cnn newsroom" starts right now. 4:00 a.m. here on the u.s. east coast and the u.s. president trump sieves soon in france for the annual g7 summit. we of course are tracking mr. trump's progress and we'll let you know when he gets there. the president impeachly though not a fan of these type of get togethers. he is going though. and looming over this year's meeting is the worsening trade dispute between washington and beijing. it got worse on friday when mr. trump announced higher tariffs on chinese imports. this after china imposed new tariffs on american goods and the dow plunged more than 600 points responding negatively, the president claimed that he was simply cleaning up the mess of presidents before him.

listen. >> china has been hurting our you country for 30 years with the money they have been taking out. other presidents should have done something about it. and they should have done it a long time ago. whether it was clinton or bush or obama, any of them. they should have done something about it. and they didn't. i'm doing it and we have no choice. we won't lose close to a trillion dollars a year to china. china understands that. i hope that with president xi, i have a good relationship, but they understand we're not going to do it. and this is more important than anything else right now just about that we're working on. >> as we monitor for the president's arrival to the g7, we have team coverage. steven chonk ounk following they florida b from beijing and also nic robertson. this announcement about new tariffs, he insists the u.s. economy is stronger and can win

a trade war. all of this in response to china's latest tariffs. what has been the reaction so far to president trump's latest move? >> reporter: george, there has been no government reaction to the latest twist. that is mr. trump increasing already announced tariffs on chinese goods. and state media outlets have largely stayed quiet. i think the swift nest of tnenes i think the swift nest of tne o move caught people off guard, but when they do respond, i think this latest move will only reinforce the notion here that his trade bullying tactics are continuing and his tendency of flip-flopping on previous positions or pledges instanstai talks. but a pre-condition that china

has set to reach any final deal is the immediate removal of all existing u.s. tariffs on chinese goods. but with these latest back and forth, it is really making that goal more elusive to achieve. >> and steven, there was also an interesting tweet from mr. trump ripping into his own hand picked chair of the federal reserve in a comparison that says this, who is the biggest enemy. you see the tweet here from the president. official white house communication. who is the bigger enemy, jay powell, he miss spells the name, or chairman xi. we'll talk more about that of course here in a moment. but the fact that mr. trump has labeled president xi as an enemy, how is that being received with the delicate talks in the balance? >> reporter: remember also we heard him talk to reporters saying that he had a great relationship with mr. xi. so which way it.

maybe they are frenemies. but according to many observers, mr. trump's tactics and his back and forth may have actually strengthened the hand of xi jinping here because of course to these observers, mr. xi was facing quite a bit of criticism within his government over his handling of u.s./china relations. but now he could really go back to his critics saying look, mr. trump is simply impossible to manage. and his tactics and his tendency of flip-flopping on his positions really shows one thing, that is china needs a strong and powerful leader to push back against the u.s. and on all fronts so that we can defeat the american plan to contain the rise of china on a global stage. so that seems to be the political implication from beijing according to many analysts. >> frenemies? i don't know can. steven, thank you. nic robertson is following the

g7 summit. and trade war is just one example of the division that these world leaders are juggling. heading into this summit, mr. trump is celebrated in in circles as a catalyst to that division. are there any bright spots for progress or might we see these divides just deepen here? >> reporter: well, one way to try to avoid showing what divisions exist is to avoid having joint communique in the end which is traditional for a g7 or g-20 type summit. president macron says he won't be having one this time because he doesn't think that it is worthwhile obviously casting his mind back to canada last summer where president trump left early, refused to sign the communiq communique. it has been difficult at these summits to get mr. trump to sign because of the way that trade issues and climate issues are described in the joint communique. but president macro will ron wi

having a speech in the next few hours so i think that we'll get to hear the french president layout what he thinks are the important issues. but he is going to be facing some of president trump's wrath as well. it isn't just china. in the past 24 hours the president has doubled down on his frustrations with the french leader over france's proposals and initiatives to tax some of the digital companies. president trump believes that this is unfairly targeting innovative u.s. companies. and he is so sfrus trais so fru threatening to reciprocate on french wine. this is how he explained it. >> i don't want france going out and taxing our companies. very unfair. and if they do that, we'll be taxing their wine or doing something else. we'll be taxing their wine like

they have never seen before. i don't like it. that is for us to tax them, no the for france to tax us. other than that, i have a very good relationship with as you know with macron as you say. and i think that we'll have a very good couple of days. >> reporter: so frenemies question mark and will he make more frenemies with the other lead ertz here. britain and italy have sort of indicated that they might follow the french method of these taxations. so president trump may find himself squaring off a couple other leaders as well on just this issue, never mind some of the others. >> the common denominator here seems to be the word fren plief. and this image from last year's summit, the u.s. president sitting in a chair, his arms crossed, seemingly separate from other world leaders. the german chancellor there angela merkel leaning in. as the g 6 plus 1 it was

described given how far apart mr. trump's administration is on many issues like climate change, multilateral trade in the face of tightening world economy and new election around the corner here state side, how might any of these pressures sway the president's america first tune in this summit? >> reporter: the president has not shown any situation of being swayed at all and it is not clear that the leaders gathering here will be in position to do that. angela merkel's economy in germany is showing negative signs at the moment. boris johnson, the new british prime minister, he sounds strong on the world stage because he is talking tough with a hard deal brexit, but he is facing a possible vote of no confidence in his government. so he is not particularly in a strong position. the italian prime minister of course arrives here having just handed in his resignation. the government in italy that he sort of balances the left and the right sides is weak.

president trump, it is not his style to back down and i don't think the leaders here are strong enough to face him. >> nic robertson live for us ahead of the g7 summit. and we are expecting the u.s. president to arrive sometime around 5:50 in the next hour east coast time. we'll stay in touch with you. thank you both for the reporting. let's flush out the nuance now with thomas gift, a lecturer in political science at university college in london joining us this hour from our london bureau. good to have you with us. a lot to talk about for sure. the french president managing expectations without putting fought the final communique and the u.s. president who snubbed signing it the last year's g7 indicating that he is not exactly looking forward to meeting with leaders this year. what are your expectations

around this trip to france? >> well, i think that you are right that donald trump is not a fan of multilateralism. and he showed a real reticence to work with international leaders in context like this before and there is really no reason i think to expect anything different going into this g7 summit. if there is something that leaders can rally around however, it is the state of the global economy. the state of the global economy is a very precarious situation at the moment precisely because of this ongoing trade war with the united states. and so i think that is going to be the big topic of conversation going into the meetings this weekend. >> and in the backdrop of course of this g7, the trade wars, jitters about a possible recession. it was interesting to see the u.s. president, who is locked in this tariff tit for tat with the chinese president sixi jinping can who is a bigger enemy, jay

powell or chairman xi. and he went further on his feelings about powell as well. listen here. >> no, i'm not happy with jay powell. i don't think that he is doing a good job at all. i don't think that he is much of a chess player. but i've got him, so, you know, that's what i have. do i want him to resign? if he did, i wouldn't stop him. >> leader of the free world there giving his thoughts about his hand-picked chair of the federal reserve. what are your thoughts about such a comparison to a public servant who simply refuses to do what the president wants and cut rates? >> it is entirely inappropriate, but unfortunately for donald trump, it is nothing new. he really views the federal reserve as the scapegoat for any economic problems that might a rise in the united states. he has been really urging the federal reserve to cut rates, thinking that the economy in the united states needs to be

juiced. precisely because there are some of these other challenges ongoing. the kind of failure of the federal reserve to pursue that path with the exception of some rate cuts about a month ago basically to donald trump is unacceptable. but federal reserves are supposed to be independent. they are supposed to be insulated from the political process. and so i really do agree with you that will kind of donald trump's insistence and calling him a villain, public enemy, are entirely inappropriate for a united states president. but unfortunately not the very surprising. >> and clearly president xi has authority to direct chinese companies to follow his direction, but in another broad side to the fed, mr. trump pushed american firms to, quote, start looking for an alternative to china. though the president insists that he has the authority to make this type of a suggestion, this is not china and wall

street responded negatively with significant losses. what are your thoughts about the president's comments here? >> simply put the president of the united states lacks the authority to impose directives on u.s. companies about where they can base internationally. so it is really a nonstarter. the president is making this case because he wants to look tough. but ultimately it is not going to have any substantive effect. the one thing that will arise out of the tariffs that donald trump is imposing on chinese imports is that lot of companies are trying to evade these tariffs by relocating to countries outside of china. basically if the end production happens in a country that is not china, they won't be subject to these tariffs. but as far as the president directing these u.s. companies where they can and cannot base, it is really not feasible. >> thomas gift, we appreciate

your time and perspective. thank you. >> thank you. still ahead here on "cnn newsroom," people are roting arou protesting around the world over what is happening in brazil, the wildfires there. how the policies of their new president helped to embolden the culprits. and defiance in north korea has it fires more missile, clear violations of the u.n. resolutions, but the u.s. president shrugs his shoulders. right back after the break. re y that's why netflix is on us. and here's another reason to join. bring in your discount, and we'll match it. that's right. t-mobile will match your discount. diarrhea?! new pepto diarrhea to the rescue! its three times concentrated liquid formula coats and kills bacteria to relieve diarrhea. the leading competitor only treats symptoms. it does nothing to kill the bacteria. treat diarrhea at its source with new pepto diarrhea.

welcome back to "cnn newsroom." i'm george howell. the crisis playing out in the amazon. the wildfires there are having a global impact and it has prompted several world leaders including the u.s. president to offer their support in fighting these flames. but brazil's president has either declined or not responded so far. although he has now called on the military to help. listen. >> translator: with respect to those who accept it, i will authorize the operation guarantee of law and order, a true vienvironmental glo.

armed forces and other agencies will not only allow to combat illegal activities, but also curb the spread of fires in the region. >> virn amountisenvironmentalisn increased land clearing and logging. he has relaxed policies to allow develop of the rainforest. cyril vanier has this report for you. >> reporter: from argentina to london to france, activists and leaders are demanding action from brazil's president. as fires burn as unprecedented rates, bolsonaro is under increasing pressure as the new government opens the rainforest for business. since taking office in january, bolsonaro has acted on campaign promises to relax environmental regulations in favor of restoring brazil's economy. he began cutting millions from

the budget of brazil's environmental enforcement agency, appointing new ministers who are loosening restrictions on mining, logging and farming in protected areas and removing those who disapproved. in early august, bolsonaro lambasted satellite data showing surging deforestation calling them lies. the head of brazil's space he research institute was then fired shortly after defending the agency's data showing deforestation was 88% higher in june compared to the year before. it equated to an area larger than 1 1/2 football fields destroyed every minute of every day. the reports led to an international alarm which bolsonaro brushed off. take that money and help reforest germany, he said last week in response to germany and norway decision to suspend funding to brazil over kens about his policy. in a rainforest critical to those depending on its vast natural resources, indigenous

groups in the amazon have rallied against bolsonaro who promised in 2017 that should he be elected, not one square centimeter of land would be designated for their reservations. >> translator: with each passing day, we see the destruction advance. deforestation, invasion, logging. we are sad because the forest is dying more he have moment. we feel the climate changing and the word needs tld needs the fo. >> reporter: as attention turns to the fires, bolsonaro calls global alarm sensationalist, a climate skeptic, he has long emphasized brazil's sovereignty in the amazon, threatening to withdraw from the paris climate accord. >> translator: brazil does not owe the world anything when it comes to virn amouenvironmenvi

protection. >> reporter: the amazon emploprs 20% of the world's oxygen. cyril vanier, cnn. and now to north korea where they are firing off missiles. south korean military says it detected proper projectiles launched earlier saturday morning. they flew toward the sea between the korean peninsula and japan. cnn following this story live in seoul, our correspondent david culver on the story. and david, what more are you learning? >> reporter: good to be with you. look, this is another early morning wake-up for officials and political leadership and military leadership here in south korea. they had a national security council gathering first thing this morning to assess what exactly was launched from north korea. as you point out, these are two 46r-believed to be two short

range ballistic missiles. they shot up about 15 minutes apart early this morning with a range of 380 kilometers. i points that out because we here in seoul are about 230 kilometers from that launch site. so certainly within that range. the u.s. president donald trump was asked about this most recent launch as he headed off to the g7. take a listen. >> kim jung-un has been, you know, pretty straight with me i think. and we're going to see what is going on. we'll see what is happening. he likes testing missiles. but we never restricted short range police stills. we' missiles. we'll see what happens. >> reporter: when he says they never restricted short range missiles, he is referring to the agreement he had directly with kim jung-un when they met in singapore. but these do violate u.n. security council regulations and they threaten south korea and japan and the tens of thousands of u.s. troops stationed in this

area. >> david, so that is in play. and remind our viewers about what is happening in the background. again, this is happening at a time where south korea and japan about, which are presumably aligned in defense against north korea, find themselves in the middle of a bitter dispute that is now limiting the intelligence they share between the two. >> reporter: no question. north korea is giving this region case in point as to why this general security of military information agreement works the way it does. this is so that intel can be shared from japan to south korea and vice versa without any parties having to come in between. well, south korea two days ago saying that they want to end that agreement. it is still going forward for the next 90 days. so we're told that the information from this most recent launch will be shared directly from south korea to japan and vice versa. but going forward, if this ends, it will bring it back to where it was prior to 2016.

and as one former commander explained it, it was as though the u.s. had to be the middle man, take the information from japan, ask if they could then tell south korea, relay to south korea. it was inefficient as they put it and it looks like it is headed back that way. >> david culver, thank you. british consulate worker is safe at home in hong kong. this after chinese police detained him for nearly two weeks. simon chang was detained for violating china's security administration punishment law which covers minor crimes. however it is not clear why he was arrested. chang was last seen on august 8th heading there as part of his job. supporters demanded that the uk do more to get chang's release. and this release comes as hong kong enters now its 12th straight weekend of protests. you've been watching many of them play out live here on cnn

and right now demonstrators are holding a large police approved rally and part of the subway system has been shut down in anticipation of this march. of course we'll continue to monitor it here for you. on the agenda, as the g7 leaders head to france, what are the goals of this summit. and what are the shared hopes by all of these leaders. we'll explain for you. plus she beat this before and now ruth bader ginsburg appears to have beaten cancer again. we'll get an update on the supreme court justice's battle with this disease. around the world and in the u.s., you are watching "cnn newsroom." so you don't have to stash antacids here... here... or, here. kick your antacid habit with prilosec otc. one pill a day, 24 hours, zero heartburn.

welcome back to our viewers here in the united states and around the world. you are watching "cnn newsroom" live from atlanta. i'm george howell with the headlines we're following for you. the trade war between the united states and china escalated sharply on friday. both sides announcing higher tariffs on each other's imports and the markets as you see responded poorly. the back and forth immediately sparked a selloff on wall street, the dow dropping more than 600 points. a change in tone from the president of brazil. now calling in the military to fight the fires consuming the amazon rainforest. the country's environmental agency is also hiring hundreds of temporary firefighters to help out. this comes at president jair bolsonaro faces mounting international pressure from european leaders. north korea has fired off two more projectiles.

they were short range ballistic missiles fired 15 minutes apart. south korea says they flew around 235 miles or about 380 kilometers toward the waters between the korean peninsula and japan. this is north korea's fifth launch this month. leaders of the g7 countries are beginning to arrive at a french seaside resort near the border with spain. on saturday president macron is to greet leaders from canada, germany, italy, i can't pan, uk a japan, uk and the united states. sunday morning they are set to get down to business for the g7 japan, uk and the united states. sunday morning they are set to get down to business for the g7. france has set five goals to combat inequality. it wants to tap into the opportunities created by artificial intellience, tackle security threats and terrorism, to promote fairer trade, tax and development policies. take action to protect the environment, and bio diversity and to promote equality in

gender, education and health care. a lot on the table there. let's talk more about it with dominic thomas. he is live this hour this berlin. good to have you. >> thank you, george. >> we've talked about this before. this does seem to be the season of division with some world leaders who are staunch anti-globalists, various trade disputes that are under way, a climate crisis not to mention the amazon. now enter mr. trump. how do you see this playing out this time? >> we've never seen anything like it. the whole purpose of the 44 previous meetings has been to bring together these major global economic powers and to talk about the main issue of the day, to reach consensus, to act in concert around these issues. we you saw the meeting in canada last year disrupted by president donald trump. as we enter in to this g7, we're

looking at a very different con figure race in terms of the political ideologies one could say of the parties. president trump is not alone at this meeting. he now finds himself alongside one of the brexiteers, boris johnson. the italian government is in disarray. and these other leaders like angela merkel for example is on the last sort of time period of her chancellorship. so not just that the configuration has changed, it is that all of the major issues that are shaping the global political discussion today from whether or not russia should rejoin the group, the question of climate, the question of brexit and so on, all going to shape these kinds of discussions. and there are radical differences between their opinions on these issues. >> and on this g7, the final communique has been scrapped. is this a move by the french

president to avoid any beingwkw seen at the last g7? >> yes, but also sets the expectations so low, you could argue that it is realistic, but don't want to be distracted. but the previous 44 meetings have produced something. the idea is that the communique shows that even if there are differences, we can agree for the good of the global order on certain issues. this is going to be absolutely impossible to achieve this. so though macron will set a priority to discuss the questions of globe global inequality, the fact is that these will be overshadowed by some of these major issues, first and foremost the crisis in brazil. and president trump right before leaving the united states tweeted out that he believes that there is a great trade deal to be done with bolsonaro in brazil whereas both macron and the european union are talking about sanctions against the

south american trade group and particularly against brazil because they are so outraged by the way in which bolsonaro's policies are impacting the environment in that particular country. so these are not minor issues around which there will be disagreement. >> and also for this g7, it will be the first time for boris john c son as prime minister to speak with these leaders. with the deadline of brexit fast approaching, what is the punch list do you believe for him going into this summit? >> for him he finds himself in a very delicate situation. and as many have argued, he essentially finds himself caught between trying to capitalize on president trump's assume for brexit in the guise of a promised trade deal down the road which has been so important to the brexiteers, arguments about the ways that the uk can position itself in the world. but this meeting is also attended of course by french president macron and angela merkel who have been explicit in

their comments about the problems that currently exist around a brexit deal. and not only is that particular issue, but let's not forget that donald tusk of the european union council is also in attendance. so boris johnson will have to navigate very carefully between these two sides in order to essentially convince the britt continue public that he still remains the person able to deliver this brexit which thus far nobody has been able to do and continues to prove extraordinarily divisive in uk politics. >> and you touched on it, but the issue of the amazon, wildfires burning there, it does have the french president demanding the issue be front and center at this g7. that international pressure though from this group of leaders, do you believe it is making a difference right now with brazil's right leaning leader? >> the influence is there, but when president trump expresses essentially his support for this

leadership, remember both candidates are heavily supported by the drillin, mining, deforestation lobbies. and so they agree on these particular issues. and i think that the problem with the g7 pressure is that without the support of the american leader, that position is ultimately weakened. but the european union does not have to worry about the united states when it comes to this. and they will be outspoken. president macron has just gone through a difficult year with a whole range of activities that have to do with the environment, burning of notre dame brought attention to the fact that there was tremendous resources around some of these questions. and also let's not forget that in the german context, on the heels of angela merkel's cdu party has been this dramatic rise. green party. so these european leaders are under tremendous pressures from their voters and constituencies that deal with the question of climate issue and global warming. and this sets them apart from some of the other leaders

present at the g7 this time around. >> dominic, thank you. and i want to draw our viewers' attention to these live images in france where shinzo abe of japan has just arrived there and we're watching again as world leaders all arrive here in the coming hours. the u.s. president set to arrive in just over an hour. and we're looking for, you know, his touchdown. we'll of course bring that to you live. you see there in the background, shinzo abe. of course world leaders will be talking on a host of issues, one big issue right now, this dispute certainly between south korea and japan when it comes to north korea. and north korea we understand firing more projectiles at a time where south korea and japan are not sharing vital intelligence. again, world leaders coming together at the g7. we'll continue to follow it for you live. u.s. supreme court justice ruth bader ginsburg has just finished treatment for

pancreatic cancer. this according to a statement from the court. ginsberg's health is closely watched because she plays a key role leading the court's liberal wing who are outnumbered by conservatives. this story from washington. >> reporter: the supreme court announced that ruth bader ginsburg has completed radiation therapy for a tumor on her pancreas. it is a in layimalignant due mo. it was treated definitively and there was no evidence of disease elsewhere in the body. she canceled her annual vacation, but she plans to continue with her speaking events. monday she will be in buffalo, new york. during the treatment, she appeared at an event in new york where she met the actress kate mackinnon who plays her on saturday night live. and thursday night she went to

moolah rouge on broadway. she also had a heart procedure and cancer in the lung last year. she spoke about her plans to stay on the court earlier this summer. take a listen. >> as long as i can do it full steam, that means at my age, 86, you have to take it year by year. >> reporter: ginsburg added that she expects to be okay next term and after that she will just have to see. the 2020 democratic presidential field just got a little smaller. massachusetts congressman seth moulton has announced that he is now out. he says it is now already a three-way race. listen. >> well, if you just look at the polling, you've got warren and sanders at about 15%. biden at about twice that. but no one else really even close. i'm not saying that is a good

thing. >> moulton says that he will run for re-election to congress and campaign for whoever gets the democratic nomination. one of the other democratic candidates is slamming his own party for its debate rules. that is colorado senator michael bennett who says that the rules will likely keep half of the field out of the next debate. listen. >> the dnc process is stifling debate at a time when we need it most. we're rewarding celebrity candidates with millions of twitter followers, billionaires who buy their way on to the debate stage and candidates who have been running for president for years. >> to qualify, candidates must get at least 2% in at least four qualifying polls and have 130,000 unique donors. bennet has not yet qualified for the debate. influential conservative billionaire david koch has dade.

he was died. he was 79. he and his brother charles koch became household names for using their wealth to back conservative causes and candidates. they funded foundations, think tanks and political groups to push their small government message. the koch family did not announce the official cause of death. cold war deja vu you could call it, the u.s. carries out a missile test and russia's president orders his military to prepare a, quote, symmetrical response. a changing world. we'll have more on that ahead for you. many doors. it's a lifelong adventure finding all of these new connections all the time. new features. greater details. richer stories. get your dna kit today at ancestry.com. to severe plaque psoriasis get clearer. and tremfya® was proven superior to humira® in providing significantly clearer skin. don't use if you're allergic to tremfya®. tremfya® may lower your ability to fight infections and may increase your risk of infections.

firing a nonnuclear missile. it is raising questions about what a symmetrical response looks like. >> what i suspect he is talking about is trying to match pace for pace or one for one the kinds of missile cape abilities that the united states is now going to look at developing. >> reporter: the trump administration wants to develop that missile now that russia has deployed their missiles near europe. mark esper takes the hardest line yet. >> right now russia has possibly nuclear tipped high enough range cruise missiles facing toward europe. and that is not a good thing. >> reporter: even though the pentagon says that it will not deploy new nuclear missiles, it has become a full blown arms race with worry putin is in the lead. >> according to some experts, he is a year or two years ahead of our ability to actually deploy in the field a similar

capability. >> reporter: u.s. military intelligence believes putin's ultimate goal -- >> they are developing the capability to deny the ability of the united states to meet its commitments in europe. >> reporter: the skyfall missile test shrouded in secrecy is just one of putin's weapons programs designed to hold the u.s. at bay. european worries about a resurgent russia still with control over crimea and attacking eastern ukraine may doom president trump's efforts to get russia back into the so-called group of seven economic fold. >> i don't think that there is going to be any serious discussion at the g7 of letting russia back in. >> reporter: and if all of this wasn't enough, the u.s. has fresh worries that the russians are developing a new nuclear testing method that may be very difficult to detect.

welcome back. in brazil, people are demanding

their government do more to fight the fires that are raging in the amazon. bloate e protestors spelled out s.o.s. on the streets. that is nearly 3,000 kilometers away from those fires. earlier this week sao paulo was plunged into darkness because of some of the smoke. let's get the latest. derek van dam is following he have detail of it. >> you know, george, i'm fearful that the fires could get worse before they get better because this is the dry season across the amazon basin. end of august into september, that is when we see the spike in the forest fires and the wildfires that take place. and that is at the heart of what we've been discussing. unfortunately, there is not any measurable rainfall in this forecast across the amazon basin, nothing significant at least over the next 48 hours. and unfortunately with the deforestation that comes along

with logging, cattle ranchers and as well as the soybean production, the damage has already been done. just through 2016, there has been already the equivalent of the size of france deforested across the amazon basin. that is an incredible amount. and we don't have to overstate the importance of the amazon. we've been talking about it for several days. it is a carbon sink, it is storing right now as we speak 127 billion metric tons of carbon. and if we continue to deforest the way that is taking place now, we will release that carbon into the atmosphere and that would be equivalent to 140 years of human induced car about anbo emissions. that is why we're fighting this. here is the satellite image. the other danger here is the smoke. the pollution. the air quality that is just being released from these fires as that continues.

check this out from nasa, this is a worldwide map of the carbon monoxide. you can see the flare in the amazon basin. and it produces unhealthy air quality just like when sao paulo was plunged in to darkness earlier this week causing a spike in their pollution and creating a very eerie scene. that was a daytime photo by the way. >> what? >> see that just plunged into darkness. >> that says a lot. we'll stay in touch with you of course as the fires continue. want to thank you for being with us for this hour of "cnn newsroom." and want to take you back to what is happening right now in the streets of hong kong. we're watching as these protests continue. a moment ago we saw tear gas being used. we'll continue to follow these events and bring you them live. and what is happening in the g7 as world leaders come together in france. stay with us. puberty means personal space. so sports clothes sit around growing odors.

eliquis may increase your bleeding risk if you take certain medicines. tell your doctor about all planned medical or dental procedures. what's around the corner could be surprising. ask your doctor about eliquis. they use stamps.com all the services of the post office only cheaper get a 4-week trial plus postage and a digital scale go to stamps.com/tv and never go to the post office again. get a 4-week trial plus postage and a digital scale take prilosec otc and take control of heartburn. so you don't have to stash antacids here... here... or, here. kick your antacid habit with prilosec otc. one pill a day, 24 hours, zero heartburn.
