what is angela merkel�*s germany? summer in berlin, and the end of an era. for the class of 2021, school days are done, new lives lie ahead. for germany, too, change is coming. angela merkel, the only leader these youngsters have ever known, will no longer be running the country in which they've come of age. we don't have a perfect democracy but i think we have a good democracy. every german citizen knows the common problems and i think in other countries, that is not the case. i love germany. it is, like, in my heart- and i never want to leave it. this country has changed significantly since these youngsters were born. come with me on a journey through merkel�*s germany. we'll explore the country she's shaped and the country she leaves behind. germany today — one of the world's economic giants. this is the land that makes cars, chemicals — even a covid vaccine. angela merkel�*s predecessors must take credit for some of this wealth, but under her leadership, the country has prospered. good times for the ketterer family, who have been brewing beer since 1877. germany's best—loved export has never gone out of fashion. anke is the next in a long line of ketterers to inherit the secret recipe and take on the family firm. did she have a choice, i asked? husband philip shares her passion for beer and took the ketterer surname when they married. germany is a rich country. its wealth depends on family businesses just like this one — the so—called mittelstand. and the world's changing, fast. german companies are trying to keep up. but germany's sense of security was shattered earlier this summer. angela merkel�*s last months in office dominated by the worst floods in living memory. the woman once hailed as the �*climate chancellor�* under pressure to do more to mitigate the effects of climate change. merkel�*s germany has reduced emissions, invested in renewables. but its current targets, many argue, aren't strict enough, and germany's still burning coal — in part because chancellor merkel abandoned nuclear power after the disaster at fu kushima. a new generation of voters is turning green. but, deep in the german forest, the damage is already done. they're cutting down acres and acres of dying woodland. these trees took 60 years to grow. they're down in just six seconds. forester hans showed us the problem. these bugs bore into the heart of the tree and kill it. they like warmer, drier weather, and climate change is weakening the tree's natural defences. all hans and his colleagues can do is destroy the affected trees to try to stop the spread. they're trying to replant, using other types of tree, which they hope will prove more resistant to a warmer, drier climate. germany's fairytale forests won't disappear, hans told us, but they will look very different in the future — and so will german society. today, more than a quarter of people living in germany have a migrant background. for years, this country has relied on migration to fill jobs, keep the economy going, rejuvenate an ageing population. but in september 2015, angela merkel welcomed refugees to germany simply because she thought it was the right thing to do. dramatic days at the munich railway station. almost1 million people would come to germany in the months which followed. for some, an enthusiastic welcome. but there was fury too. "wir schaffen das," said angela merkel, as she tried to reassure a nervous country and a bewildered europe. "we can do it." six years later, many here would argue she was right. the sense of crisis has long passed. but that autumn has redefined german politics, german society. for those of us who were here in september 2015, it felt as though we were witnessing something extraordinary. for many of the exhausted men, women and children arriving here, it was, of course, the start of a new life, but for germany, too, it was the beginning of profound change. i first met megan earlier this year, when i went to get a filling repaired. she's an apprentice here and plans to train as a dentist. hard to imagine now, that this confident young iranian nearly died five years ago as she and her mum fled to germany. even now, some germans — a minority — are still furious with angela merkel. they point to migrant crime, terror attacks. a far right anti—migrant party now sits in the national parliament, fuelled by lingering resentment, which is particularly strong in places like gorlitz in the former communist east. this is one of germany's most beautiful cities. you might even recognise parts of it — it's often used, sometimes even by hollywood, as a backdrop for historical drama. but behind the facade, this place and many others like it in the former east, have a serious problem. when the iron curtain fell, people here were promised blooming landscapes. but 30 years on, opportunities are still fewer, salaries and pensions lower than the rest of the country. it's still hard to convince young people to stay. i came to talk to hannelore and herfriends. they all support germany's far—right party, afd. merkel�*s germany, her decisions, didn't always go down well with her european or her global counterparts. but, under her leadership, the country has wielded considerable influence. asjean—claudejuncker knows only too well... hello, nice to meet you. as a former president of the european commission, he worked closely with angela merkel through turbulent years. financial crisis, greek debt crisis, migrant crisis and brexit. she was. . . not easy to deal with. because, as a scientist, she was always reasoning in perspective. germany today is seen as a very peaceful, peace—building country. merkel had, to some extent, an added value. she developed a kind of — in the noble sense of the word — a european feeling. she has, as a legacy, something people don't know, because after angela merkel, they will be no other german chancellor not being pro—european. everyone knew that germany was the biggest amongst member states and that the german economy was, to some extent, predominant. she never said, contrary to others coming from bigger member states, she never said "i'm telling you as the german chancellor, that. she never gave inside the european union the impression to others that she was the big boss on board. so she was not the queen, but she's a nice princess. is the eu better place for having had angela merkel as part of it? i think so. europe is a better place to be after having had her as a german chancellor. perhaps angela merkel�*s greatest struggle came at the very end of her chancellorship. germany, like every other country in the world, learning now to live with covid. after one—and—a—half years, gemany�*s artists are getting back on their feet. was the corona crisis one of those rare times when people got the opportunity to see where germany's priorities lie? every country in the world, the priority was on economics and also i understand that. anyway, economics and society, vaccination, medical help this and all that, and then after a long list, culture. for the feeling as an artist who needs an audience, it is frustrating, yes. gabrielle describes other challenges, too. how, for example, should artists deal with the past when it's as troubled as germany's? of course, with our history, germany has always a problem to identify himself. i think this is the challenge for germany in the future. never to forget what has happened, and, kind of, to educate the whole population. we need, kind of... to settle up and to handle up and appreciate our long history, even before, before the nazis, and everything is in, like philosophy, drama, poems, the music and so on. i see proudness in a lot of country, all over the world. but in germany it's very difficult to be proud, so it's not good. when the historians of the future open the merkel files, how will they assess her time in office? does german society reflect her values? after 16 years of angela merkel, what does it mean to be german today? it's a present—day characteristic that people do not reflect on this too much because they are aware that it doesn't bring anyone anywhere, to think about national identities. the main legacy of angela merkel is to have represented this rational, pragmatic, solution—orientated development in the german society. she is representing this sort of thinking in the world, which — have a look at donald trump, have a look, maybe, at borisjohnson... it is more shaped by people who have nationalistic or irrational or narcissistic or populist approach. in germany, i think most people would say that this rational, scientific, analytical approach, in the long run, promises to be more efficient — hideous german efficiency. will angela merkel be remembered as a great chancellor, do you think? i think so, yes. and, in the long run, people will see that these 16 years have been, if you sum it up, quite successful. not only economically, but also in shaping the country towards preparing it in the european and global sense for a future which will not be easy. that future, and its challenges, will fall to the new generation of politicians. and they, in turn, must listen to the voice of a new class of voters. now we have to stand up and say, "ok, stop driving cars, stop flying to holiday," because we need to reduce the emissions, which is right, but we should have also already done this, like, 50 years ago and notjust now, so i think it's our turn to act and ourturn to, yeah, take action. but it's not all our faults. do you feel as a younger generation that you have been listened to? that your ideas have been taken on by the government? yes and no. so i think, yes, they are listening to us, but i don't think that they take us serious, or enough serious. but i think in the last years, we've seen that the politician system is moving more and more in our direction. germany is good but i the migration system, like, everyone has, like, i a chance to live here and to achieve his, get his dreams. viewed from afar, the world of german politics can often look rather boring. it's all about compromise, consensus, continuity... in that sense, angela merkel has given her country what it expects from a leader. in a turbulent and shifting world, the voice of calm. hello there. for central and southern parts of the uk this week, it's not looking that bad at all. with high pressure always nearby, it'll be dry, quite warm with plenty of sunshine. but we'll start to see some changes from wednesday onwards across the north of the uk, more especially for scotland, where it will turn windier with some rain at times and it will feel cooler. so, a bit more of an autumnal feel there. high pressure, though, dominates the scene into tuesday, many places starting dry. there will be some mist and fog around, some dense patches across east anglia and the southeast which will tend to dissipate through the day. bit of mist and fog to start the day for scotland and northern ireland, and then it'll turn cloudier and windier for western scotland, perhaps western northern ireland, with some light and patchy rain here. but eastern scotland, eastern northern ireland, most of england and wales, fine and dry with some sunshine. and again, quite warm, into the low 20s celsius. into tuesday night, it starts to turn cloudier, windier and wetter across the northwest of the uk. further south, closer to high pressure, winds will be lighter, some clear spells again, one or two chilly spots, but a bit milder further north and west. this is where we start to see the changes, then, around the middle part of the week. indeed, it's on cue during the autumn equinox, with some rain and strong winds pushing in to scotland, northern and western areas, and then this band of rain will move southwards into northern ireland, southern scotland later in the day. behind it, sunshine, blustery showers, gales here. to the south of this rain band, though, for the majority of england and wales, another fine day to come. quite warm, top temperatures of 22 or 23 degrees. as we move into thursday, another area of low pressure skirts the north of the uk. that'll bring another swathe of wet and windy weather across scotland, maybe some gales later in the day. a bit more cloud further south, but again, for much of england and wales, the midlands southwards, it'll be dry with some lengthy spells of sunshine, top temperatures 20 or 21 degrees. but cooler in the north, 10 to 16 degrees here — particularly chilly when you factor in the wind. through friday and into the weekend, we start to see the winds change direction. low pressure develops to the west of the uk. that draws up some mild south—westerly winds across the uk, but we'll start to see some wet weather pushing into western areas as we reach part two of the weekend. but again, across the south, it could stay dry with plenty of sunshine. welcome to bbc news. the top stories. 0pening welcome to bbc news. the top stories. opening the doors after more than 550 days, the us announces it will end a ban on international air travel for fully vaccinated foreign nationals. we have a special report from afghanistan — on the dire conditions the un says are leading to a humanitarian disaster. and lava continues to flow on the spanish island of la palma — officials say it could trigger explosions and toxic gasses when it reaches the sea. these are the strongest forces of nature at work in a spectacular but destructive display, and the only option is to get out of its way. it's certainly been a long time coming: the united states
