>> brennan: welcome back to "face the nation." thursday is earth day, and president biden will be hosting a global virtual summit to discuss the climate challenges facing us all. cbs news is devoting this week the to an extensive look at climate change in our series "eyon earth: our planet in peril." we pick up our interview with french president emmanuel macron on just that topic. i want to ask you about climate. president biden brought the u.s. back into that

paris climate change accord about three months ago. but many have not actually met their targets, and now president biden is going to ask for further cuts to emissions. what makes you think it will be achievable this time? >> yes, i think because nw it is time to believe and time to rush. and president biden is one of those persons to do so. but i think the decisions taken by your president this year was super important. welcome back. i was extremely happy because now the u.s. and the federal government decided to join again and to commit. second, as europeans, we increase our targets for 2030 and 2050 a few months ago because, indeed, we were lagging behind in comparison to our targets. and now we have to act. because we are living the first consequences of basically climate disorders. this is even more urgent than five years ago. so your -- >> brennan: but don't

you need china and india to make those commitments? >> i think, yes, you're right. we need two things: we need to accelerate innovation and ability to deliver. we need india and china to be with us. india is very committed. and they are an american country. they have democracy. but they launched with us the initiative two years -- three years ago now. they are improving the system, and they committed to reduce, especially emissions since they are super polluters. china remains in paris agreement. they increased their targets, but they are set for carbon neutr neutrality in 2060. thewe want to work with the

u.s. and with europe, first to accelerate the target of 2030 to have the peak emissions, and some cities and regions to do better and faster. >> brennan: don't leaders like yourself need to just speak plainly to the public and say, look, this needs to happen. it may cost you your jobs, it may mean prices go up, but this is a price that all of you have to pay in order to meet these targets? >> look, i think obviously we will have to change a lot of things in our economy. we have to increase the price of carbon, and we have to help this to happen for entrepreneurs in our households. if you go to the white house to say, now, guys you there have to adapt yourself and you will have to pay a higher price, i can tell you you wil increa

inequalities. you have to accompany people, and we have to accept for a few years to invest public money in this position, to help innovation and distribution of this innovation. you have to accept the business model and have your investors to finance green investments and to penalize those who do not make this move. and you have to accompany your households to make it feasible for them. we have to help middle class and poor people to make this change with us. this is a comprehensive program. i'm more sure because i made mistakes myself. >> brennan: bo ukraine right now. if

vladimir putin invades? >> i think this situation is unacceptable. russia has to deescalate. this is clear. the level of tension at the border is both counterproductive and inacceptable. we want to political process to deal with -- >> brennan: vladimir putin has blown that off for years, and sanctions have not stopped him. the diplomatic efforts have not stopped him. you, yourself, have referenced nato as being brain-dead. what is actually going to stop vladimir putin from invading? >> i think what happened a few years ago, when ukraine was invaded, it is not th the failure of diplomacy. it is the failure of credibility, vis-aà-vis russia. when we make the lines, we have to make them

respected by our people and the orders. and i think we have to be clear and tough. it was a failure of a naive approach with russia. i'm definitely in favor of discretion with russia, with an open, quiet, and resolution with russia. but i think when we put red lines, we have to be sure to be credible and to make these red lines respected by the orders. >> brennan: understood. >> if we want to be efficient, we have to accelerate the diplomatic agenda and u.s./europe -- all of us have to be very clear that we will never accept a new military operation on the ukrainian soil, and we havto bey to be edible. >> brennan: do you think that what president biden did with sanctions will make any difference to vladimir putin this time? will it stop him? >> i think we need an

approachapproach to be clear bad on two pillars: one, dialogue. and i fully share the willingness of your president to dialogue. and i'm sure that president putin can be ready to reopen dialogue. but if we want a better system in terms of arms control, if we want to stabilize a lot of existing crisis in the world today, we need an open and frank dialogue with russia. >> brennan: will you sanction russia if they -- >> when we are not aligned. and i think after an unacceptable behavior, indeed, we have to sanction. this is what we did after ukraine or after a series of crisis which happened. and i think we have to define clear red lines with russia. this is the only t be credible. i think that sanctions are not sufficient in themselves, but sanctions are part of the package.

>> brennan: mr. president, i'm being told that we are running out of time. but i want to thank you for your time today. >> thank you very much. i was happy to answer your questions. and just want to pass a very clear and simple message: i think we are, all of us, in the middle of a terrible crisis and a lot of fears, covid-19, climate change, and so on, and inequalities and so on. i do believe that our common values, i do believe that our facing will havto regulate this capitalism. we will have to reinvent a new narrative and new actions, and new investments in green

technologies. i think we have the opportunity to do it together. and to build and invent our future. i'm a strong believer in this positive and ambitious agenda together. and i hope we will deliver hand-in-hand. together. >> brennan: we will watch for that, mr. president. thank you. there was some big foreign news last week, after almost 20 years, america's longest war will finally come to an end. as president biden announced that all troops will be out of afghanistan by september 11th. u.s. intelligence warned that the taliban will regain control of the country. more than 20,000 were wounded. we honor them and their loved ones for their service. we'll be right back. n

>> brennan: we spoke

with president biden's ambassador to the united nations, linda thomas-greenfield, earlier. and we asked about the upcoming climate summit, where the president is expected to press world leaders to make fur emissions. what new pledges has the u.s. secured? and without india and china on board, isn't this going to be a bust? >> i don't think it is going to be a bust. in fact, i think this is an opportunity for us to hear from other countries what new commitments they intend to make. we intend to encourage them to up their game and to openly express in this forum what they intend to do to deal with climate change. and we hope that india and china will join us. >> brennan: i want to as a thousas of refugees who have learned that they are now stranded. they thought they were coming to the united states, but they're in

limbo because president biden signed this cap on refugee emissions. this historically low number of 15,000. why did he break his promise? >> i don't think the president broke his promise. we're looking at -- this is a first step. we're looking at the infrastructure that we have in place to support bringing refugees into the united states. that infrastructure was basically destroyed over the past four years. and so this is just a first installment, and i know that the president intends to revisit those numbers over the course of the next few months. >> brennan: well, just two months ago the president said he would up it to 62,000, and yesterday he signed paperwork capping it at 15,000, and the white house cited unspecified burdens on the office oft

the border is stopping accepting refugees from all over the world? >> i don't think that is the case. i worked on refugee resettlement issues, and i know that to bring in refugees requires a very comprehenexpensive infrastructue of agencies that are involved in processing refugees, and agent see agencies that will -- we have to ensure we can bring refugees into the united states in an orderly fashion. and i know that is what is right now under serious consideration and work. and i expect that our numbers will increase. the president is committed to refugees, he made that clear during the campaign. and he has made it clear over the past week. > brennan: so you do expect that goal of 62 isrea,500 to be met?

>> i know how challenging it is to reach it, but i can say without any doubt that every resource we have able to us will be used to reach that goal and possibly even going beyond. >> brennan: this past week you gave a speech that i want to ask you about because it has gotten quite a lot of attention. you said the original sin of slavery weaved white supremacy into our documents and principles. kiing of georgoydthe discrimination against muslims and asian-americans. are you saying we're diluting ourselves? >> no. i think we're being tremendous leaders. our country is not perfect, but we continue to perfect it. though imperfections are part of our history.

and we have to talk about them. it is our strength that we can talk about our calnsfections to the wor ose sam imperfection a criticism. it is an acknowledgment of our history. it is an acknowledgment of where we started. but we need to look at where we've come. the fact that i came from a segregated high school, and i'm now the permanent representative of the united states at the united nations says everything about what our country is about. and i look forward to continuing to engage with other countries, to use our example to show those other countries what they might achieve. but we still have a lot of work to do. and we have to acknowledge that, but we also have to work to continue to improve our country. >> brennan: but it is

precisely because of the role that you have as a cabinet member that it drew so much criticism. and the wall street journal editorial board called you the ambassador of blame america first. it said it sounded like you were sounding chinese propaganda, and your job was to bring critical race theory to the world with a focus on criticizing your own country. to be fair, were you comparing bigotry in america to mass atrocities carried out against minorities around the world? >> i was acknowledging what is a fact in the united states. racism does exist in this country. and i think it was a powerful message. imagine any other country doing that. our country -- the uniqueness of our country is that we can self-criticize, and we can move forward. and our values are clear. and the purpose of that speech was to lay out our values, but also

acknowledge our you wil a chinese wee uighurs getting on a chinese stage. i'm not comparing our situation. i'm acknowledging that we've come a long way. i'm very proud of what we've been able to achieve. but i'm realistic about what we have to do moving forward. and i think if we are going to be a voice around the globe for raising issues of human rights, we cannot white-wash our own issues in our own country. >> brennan: ambassador, i really want to ask you about tea gray. you said this week to the u.n. security council, do african lives not matter as much as those experiencing conflict in other countries? you were challenging them

because of the systemic rape, the gang rapes, that are being carried out against young girls in tea , in tconflic i ethiopia and eritrea. it has been called ethnic cleansing by the united states. why haven't we heard from president biden and vice-president harris about this concern? what is the u.s. doing? >> well, i think you have heard from president biden because you've heard from me and you've heard from secretary blinken. president biden has engaged with the ethiopian government. secretary blinken has engaged with the ethiopian government. president biden sent senator coons to have discussions with the ethiopian government and lay out our concerns about the horrific situation in tea gray. and as the u.s. representative on the security council, i thought it was important that the security

council's voice also be added to the voices of concern about the situation there. we had seen -- >> brennan: well, you're clearly saying what is being done is not enough. >> it is not enough. and that's why i raised it in security council, because i think we have to make sure that the victims hear our voices, but also the perpetrators. know that we are concerned and we are watching this situation, like we're looking an addressing situations elsewhere in the world. so, yes, i agree with you, more has to be done. and that was the purpose of my raising this issue. >> brennan: ambassador, i'm told we are out of time. thank you for your time today. >> thank you very much. >> brennan: late yesterday president biden said that he limited the number of refugees entering the u.s. due to the influx of child migrants at the u.s. border. we couldn't do two things at once, he said, but he has promised to increase

the numbers. we'll be right back.

>> brennan: other than u. seen more deaths due to

covid-19 than brazil. the international medical aid agency, "doctors without borders", is descridescribing the situation there as a humanitarian catastrophe as the country's daily death toll is now the highest in the world. cbs news national correspondent ma ma manual spent the weekend there. >> reporter: the i.c.u.s, which are overwhelmed, some running low on the medicines needed to intubate patients. all of those are covid-19 patients, there is no room for others. and the doctors we spoke with said many are younger, in their 20s, 30s, and 40s, and once they get here, the odds are not good. how many people in this

room will recover? >> less than half will cover. recover.[speaking foreign language] >> reporter: you're the last person they see before they die. the fight against the virus has been a political one from the start. the governor of sao paulo says he feels like he is fighting the coronavirus and the bul bullsinao virus. are you still advocating for a lockdown right now? >> we are advocating a lockdown right now. at this time, please stay home. >> reporter: the virus has ravaged brazil's economy. and as cases surge, so does food insecurest. insecurit. we found a man, who in

between bites of a donated lunch, which he has come to rely on, he made it clear to us his options are stark. he did this, meaning robbing people would be the other option.[speaking foren language] >> reporter: because there is no opportunity? >> uh-uh. >> reporter: the burials are happening one right after the other. there were about seven in just the 45 minutes we were there. and the crews are having to dig up graves and bury bodies around the clock. the world is concerned about what is happening in brazil, and not just from the standpoint of human suffering, and that's because the more the virus spreads, the more it can mutate. >> brennan: our manuel bojorquez reporting from brazil. we'll be right back. finally, with the help of her doctor, it came to be.
