sell out in less than a0 minutes. joe biden has become the first sitting us president to visit the amazon rainforest. he's arrived in the brazilian city of manaus, where he's meeting local leaders working to protect the region's ecosystem. in the past hour he has phone over a stretch of the rainforest and is expected to see the rio he go and amazon rivers. he will continue on to rio dejaneiro for 8620 summit which on monday. let's speak to our correspondent rowan bridge, who's in washington.

i want to start by asking about the significance of his trip, the significance of his trip, the first by a sitting us president. it the first by a sitting us president. the first by a sitting us resident. , president. it underlines in some ways _ president. it underlines in some ways the _ president. it underlines in some ways the ways - president. it underlines in some ways the ways that l president. it underlines in i some ways the ways that joe some ways the ways thatjoe biden has made climate change and the green investment assertive signature of his time in the white house. he passed $1 trillion inflation reduction act and if you look underneath the hood there were billions of dollars to transform the us economy so there was financial incentives for things like electric vehicles and battery plants, electricity generation, so solar and wind and things like that and as part of this trip to the amazon he will promise another $50 million towards the amazon fund which aims to make the amazon a sustainable place. it really underlines his efforts to put climate change at the top of the agenda and that will be a

stark contrast to what we are going to see when donald trump takes over in the white house on january the 20th.— takes over in the white house on january the 20th. explain a little bit about _ on january the 20th. explain a little bit about that _ on january the 20th. explain a little bit about that contrast, i little bit about that contrast, because the incoming trump administration does look likely to scale back american efforts to scale back american efforts to combat climate change, which as you say is a stark contrast with whatjoe biden are saying and doing. with what joe biden are saying and doing-— with what joe biden are saying and doinu. ., ., , and doing. there are two things i would point — and doing. there are two things i would point to _ and doing. there are two things i would point to it. _ and doing. there are two things i would point to it. if _ and doing. there are two things i would point to it. if you - i would point to it. if you look at the picture energy secretary, chris wright is a man who runs a company called liberty energy which has an oil and gas company based around fracking who said in a video on his linkedin page that he didn't think there was a climate crisis so he is clearly a climate sceptic and joining the campaign donald trump became famous for saying drill baby drill on the campaign stage to great cheers, a reference to allowing greater fossil fuel extraction when he is in the white house. if you

look back to the last time donald trump was president, he took the us out of the paris accords on climate change so i wouldn't be surprised if we saw a similar move when he comes back into office injanuary. this trip to the amazon rainforest by president biden, what kind of impact can it have? , ., , ., . have? the question is how much of what he _ have? the question is how much of what he says _ have? the question is how much of what he says or _ have? the question is how much of what he says or does - have? the question is how much of what he says or does is - of what he says or does is actually sustainable. joe biden can promise all these things but the question will be about how much of that he is able to put into a form where donald trump is not able to reverse it. that will be the crucial test to all of this. the climate change agreement, and it was a democratic president that took the united states into it but donald trump was able to reverse that with executive action effectively taking the us back out of the

climate accord. the question forjoe biden is how much of this stuff is he going to be able to put in a form that is not easily reversible by donald trump. not easily reversible by donald trum -. �* , ., ., trump. and then it is on to rio de janeiro _ trump. and then it is on to rio de janeiro and _ trump. and then it is on to rio de janeiro and what _ trump. and then it is on to rio de janeiro and what are - trump. and then it is on to rio de janeiro and what are we - dejaneiro and what are we expecting president biden to do at the meeting of 620 leaders? this is a meeting of 19 of the world's biggest economies plus the african union and european union and they discuss the issues facing the global economy. i know brazil have said they want to focus on sustainability and global inequality so those are the issues that will be high on the agenda at this meeting. interesting to note that one of the people that is part of the 620 is russia but vladimir putin is not going to be there. thank you very much and we will find out more about what is going on at the 620 shortly but thank you very much.

after meeting indigenous leaders ,joe biden�*s next stop will be in rio dejaneiro for his final 620 summit as president. he'll meet leaders from around the world at the annual summit — which is being seen as a test for brazil's president lula da silva who has suggested a tax on the super rich. let's speak to erica york, senior economist and research director at the tax foundation — an international think tank based in washington. first of all, back to basics, what is the supertax that president lula da silva is suggesting?— president lula da silva is su~estin~? , ., suggesting? there has been an increasin: suggesting? there has been an increasing push _ suggesting? there has been an increasing push to _ suggesting? there has been an increasing push to adopt - suggesting? there has been an increasing push to adopt a - suggesting? there has been an increasing push to adopt a tax. increasing push to adopt a tax on net wealth and make it be a global tax on net wealth and we have seen discussions of this over the past year and we have seen the united states under the biden administration express opposition to the idea of creating a global wealth tax

and it has been a big barrier to adopting it because unless the us is on board it becomes impossible and opposition would continue and become even more strong under the incoming trump administration.— administration. there are suworters _ administration. there are supporters globally - administration. there are . supporters globally including france, spain and south africa. how much will this dominate the agenda at the 620 summit? it is robabl agenda at the 620 summit? it is probably going _ agenda at the 620 summit? it 3 probably going to be a big topic of discussion but it is also worth stepping back and asking, does it make economic sense to push a tax like this? if we look at the adoption and then the repeal of wealth taxes across europe we have found they tend to be very administratively costly for the revenue they bring in and that they encourage flight of capital and of wealthy people out of the taxing jurisdictions so they become very distorting and discourage risk—taking and

entrepreneurship and having high administrative costs, and the discussions we have on tax should be shifting away from taxing wealth, and instead look at how we can encourage more growth and more competitiveness. i growth and more competitiveness. growth and more cometitiveness. ~ ., competitiveness. i know you have also — competitiveness. i know you have also been _ competitiveness. i know you have also been working - competitiveness. i know you have also been working a . competitiveness. i know you have also been working a lot competitiveness. i know you i have also been working a lot on the tariffs of that president—elect donald trump wants to bring in, campaigning ona wants to bring in, campaigning on a serious escalation of tariffs. what is the impact of potential us tariffs on chinese goods? potential us tariffs on chinese aoods? , ., , potential us tariffs on chinese aoods? , , ., goods? trump has proposed a serious escalation _ goods? trump has proposed a serious escalation of- goods? trump has proposed a serious escalation of the - goods? trump has proposed a serious escalation of the trade where he started in his first term in office, suggesting tariffs of 60% or more on everything the united states imports from china. if that were to occur it would be a massive disruption that would shock the markets and supply chains and the us economy and the global economy. the

question becomes how farand how quickly does donald trump act on this promise once he takes office and the second question is does the united states take a go it alone approach when addressing trade issues with china or do we partner with other groups and trying to address these with china? {131 address these with china? of course president—elect donald trump will not be at the 620 summit in president biden will be. what do we expect from his final 620 summit as president? i think from biden we will see more emphasis on what he has emphasised with the industrial policies has implemented, the subsidies for green tech and wanting to see those going forward but there were also be very big questions about how do all of these us policies shift when the trump administration comes into office and i think it creates a real environment of uncertainty because we know the us under president trump

will have more scepticism towards those initiatives but there is a question of exactly what actions that trump proposed on the campaign trail he will follow through with and what the response from other countries will be. one of the biggest questions being what position does the us take in cooperating with other groups versus how much does the us turn in word moving forward. thank you very much, erica yorke, senior economist and research director at the tax foundation. russia has launched a massive attack on ukraine's energy infrastructure — the worst in months — with dozens of drone and missile strikes. in kyiv, people sought refuge underground, as the strikes cut power to the capital. there were blackouts in dnipro, where two railway workers were killed. air strikes cut power in the eastern region of donetsk — and to the west, in lviv, a woman was killed. in the south, in mykolaiv, drone strikes killed two people. six more were injured, including two children. 0desa was also targeted — resulting in power cuts across the region.

and there were attacks too on vinnytsia and volyn — with multiple strikes putting huge pressure on ukraine's defences. with the latest on one of the biggest combined attacks of the war, here's our correspondent, paul adams. this was one of the largest attacks in months. the missiles and a drones targeting cities all across this vast country. the south was hit hard. rescue workers were busy from first light, dragging survivors and bodies from the wreckage of homes. after almost three years of this, there is exhaustion and fear that this is what the long winter months have in store. ukraine's electricity grid was the main target, triggering power cuts in several cities, and when the power goes so too does the

water. forthe power goes so too does the water. for the people of 0desa, a long trudge to the nearest emergency supply. i don't think we will get water today, says julia. maybe tomorrow in the evening. president zelensky congratulated the men and women of ukraine's air defences. including the tallia, shooting down her very first cruise missile. did it hit, someone asks? yes, comes the answer. if you look at the map it is difficult to find any place in ukraine where the missiles were not targeting and one of the missiles even crossed the moldova border this site. find moldova border this site. and k iv moldova border this site. and kyiv parts _ moldova border this site. and kyiv parts of— moldova border this site. and kyiv parts of a _ moldova border this site. and kyiv parts of a missile shot down by ukraine air defences leaving a trail of destruction in its wake. when the sirens sounded some headed for the capital's famously deep underground. after almost three

years most stay at home but winter is approaching and russian forces are advancing in the east. there is a renewed sense of pessimism and danger. in berlin, prominent russian opposition figures are leading a protest against president putin and the war in ukraine. among those taking part, yulia navalnaya — widow of russian opposition leader alexei navalny. next to her, the russian journalist and former political prisoner vladimir kara—murza. they took to the streets as details continued to come in of the full extent of last night's missile and drone attack on ukraine. the crowd are shouting freedom to political prisoners. that is
