achieved if donald trump withdraws american participation? also coming up, return of the tariff man, as the uk launches international trade week, participants are left to wonder if a new era of us protectionism is looming. plus, voices of moderation. we meet the people who watch disturbing online content so you don't have to do. we started in baku, where global leaders are looking to rein in climate change at the cop summit. last summits, the paris agreement, they agreed to set a

goal of 1.5 increase in temperature. they were due to be told that they are going to preach that this year. rich nations are contributing $100 billion a year to help developing countries adapt to climate change. many say that is not enough and someone to cramped up to $1 trillion a year. 0vershadowing the whole event is the return to the white house of donald trump, as are north america business correspondent reports. dubbed the climate finance cop, the central goal of this meeting will be to agree how much money will go each year to help developing countries cope with climate —related costs. the talks will be difficult after donald trump's ray election victory. he is a climate sceptic. he has vowed to remove the us from the paris agreement for a second time.

the big concern is that anything us negotiators agreed to will be meaningless once the new administration gets in, removing the incentive for the likes of china and india to make big commitments. the outcome of _ make big commitments. the outcome of the _ make big commitments. the outcome of the us _ make big commitments. tue: outcome of the us elections make big commitments. tte: outcome of the us elections is going to impact the negotiations. it has an outsized responsibility not only to reduce its emissions, but also provide finance and the us not being at the table is going to really affect the negotiations on a big way. at negotiations on a big way. at the same time to new trump administration is likely to push for a major ramp up of oil and gas exploitation in the us, roll back environmental protections as well as impose heavy tariffs on electric vehicles and solar panels from china. with renewable energy gaining support in the us, trump's efforts to boost oil and gas may be less effective. you could face strong opposition within his own

party, given the inflation reduction act which could channel $1 trillion into green energy has been hugely beneficial to republican districts. let's bring in the norika value, associate professor of economics at the university of simon paolo. thank you for being with us today, laura. as this cop begins, what are your hopes, fears about the possibility of a breakthrough? well, i think everyone is concerned with the recent results in the us elections. public sources of funding from

developed countries into the target, the so—called new collective goal which is the amount of money that countries will commit to fight climate change in the global south in the next years. the negotiations were not easy before the us elections, developing countries want much more. they need has been estimated at 2 trillion a year depending on the study, or1 trillion a year. the current target set is 100 billion, which is largely insufficient. my which is largely insufficient. my after the election of donald trump in the us the prospects are even harderfor the financial commitment. fire are even harder for the financial commitment. are you aaivin u- financial commitment. are you giving up hepe? _ financial commitment. are you giving up hope? is— financial commitment. are you giving up hope? is the - financial commitment. are you giving up hope? is the whole l giving up hope? is the whole cop process are nice as long as you have someone hostile to it in the white house? t you have someone hostile to it in the white house?—

their own political turmoil, so we are less hopeful for germany which has been a player in the past. we hope that the uk and other european countries step up. and of course china has a big role to play, as well. the question here is whether china will even be considered as part of the contributor base to this financial commitment since the has always put the burden into the historically responsible

countries for omissions and china is not included in that. we will have to live there. thank you very much for sharing those thoughts with us today. today, international trade week is being launched in the uk. donald trump has threatened tariffs up to 60%. it could mean a huge hit to us exporters. should the uk try to do a deal with donald trump or is it time to look at rebooting trade relations with the eu? that is the question be put to the trade expert, rebecca harding. the trade expert, rebecca hardin. ., , harding. the uk trade will be affected enormously - harding. the uk trade will be affected enormously if - harding. the uk trade will be affected enormously if there | affected enormously if there are tariffs and it will also affect things like inflation, things like growth. the governor of the bank of england andrew bailey last week said that he was holding a watching brief on what happened in the us because it might have an impact long term loan interest rates and how quickly they come down. obviously the relationship with the united

states will be incredibly important. what is really interesting is that we know about donald trump, we know what happened last time, we know that he is a wild card, so he is kind of a known unknown, if you know the timing. the role of trade in the uk labour government is actually quite different to the roles are played in the past governments, so it is part of the growth agenda. it is more on close relationships with allies rather than on trade deal specifically, so you have a very different set of conditions here in the uk, compared to what we had before. here are some statistics. it illustrates this game of social media today. more than 4 million photos are uploaded to instagram every hour. 500 hours worth of video are posted on youtube every minute and it is estimated 30 million videos are uploaded to tick—tock every single day. as we know, some of

it is harmful, disturbing or illegal, so who are those people who have to sift through it all? our technology editor has been exploring the hidden world of content moderators. some viewers could find the descriptions of content in this piece upsetting. if you report something on social media, it's lancing the entry of content moderators. they can end up watching child abuse, hate speech and murder. they are hidden away. many to work directly for the tech giants. there are content moderators in the uk but they are often outsourced to other companies and therapy caps in places like east africa, india and the philippines. indie places like east africa, india and the philippines.- places like east africa, india and the philippines. we are the one to make — and the philippines. we are the one to make sure _ and the philippines. we are the one to make sure they - and the philippines. we are the one to make sure they are - and the philippines. we are the| one to make sure they are safe.

in doing that, we are the ones who gets... this is mojez, who lives in nairobi. for a year from april 2022, he worked as a content moderator for a company that tiktok had outsourced this work to. any disturbing content that you can imagine, you know, from sexual, you know, materials or content to very disturbing content whereby people are being, you know, beheaded or killed or skinned alive, you know, to, you know, kids being molested. the job hugely affected mojez�*s mental health. he feels he wasn't given proper psychological support or paid enough. having issues with insomnia, you know, losing weight, content moderation is an industry in crisis. there are multiple ongoing legal claims that the work is destroying the mental health of the moderators. we've spoken to several former outsourced content moderators for meta, which owns facebook and instagram, as well as tiktok and chatgpt, and they've all told us similar stories.

but despite their work and the rise of ai tools designed to catch harmful content before it's even published, the torrent of horrific material that finds its way online continues. campaigners say these workers are essential to keeping us safe online and that they should be treated better. in the uk, we've seen a lot recently what happens when social media companies don't properly invest in keeping their platforms safe. really, the only thing that's between me logging on to a social media platform and watching a beheading is somebody sitting in an office somewhere watching that content for me and reviewing it so that i don't have to. these are some of the richest companies on the planet and they can afford to invest in proper, safe content moderation. a tiktok spokesperson said that it knows that content moderation is not an easy task, and it strives to promote a caring working environment for employees. this includes clinical support as well as creating programmes to support moderators'

wellbeing. it added that videos are initially reviewed by automated tech and said that this removes large volumes of harmful content. meanwhile, openai, the company behind chatgpt, said it's grateful for the important and sometimes challenging work of its ai trainers. a spokesperson added that along with its partners, openai enforces policies to protect the wellbeing of these teams. and meta, which owns instagram and facebook, said it requires all the companies it works with to provide 2a hour on site support with trained professionals. it added that moderators can customise their reviewing tools to blur graphic content. i'm very proud of the work that i did despite the challenges, you know? the working environment being, you know, very terrible. i came to understand the importance of the job in itself, in protecting the users, being the front line people, to make sure the users are safe.
