just a single rotation of one of these turbines can power the average uk home for an entire day. as i've been finding out. it's all part of the uk's aim for a sustainable energy revolution. it's actually much smoother than it looks. if you thought your commute to work was rough going, check this out. we are with a team trying to get out to service a wind turbine. so the north sea is famous for its savage weather. but that's why they have put the wind turbines out here, because this is where the wind is. but of course, it means they are very hard, whoa, to maintain. the swell is up to

three metres high today. making it too dangerous to climb the ladder. so it's back to the ship for us. this is where the team of engineers who keep the blades turning live and work. coming through. these guys do 12—hour shifts out here, for m straight days, and then gets two weeks off. it can be tough, but the flourishing offshore wind industry is creating thousands of well—paid skilled jobs. most of them in places like grimsby in east yorkshire that have seen traditional industries decline. my grandad went to sea when he was m, as a cabin boy. for seafaring families like mine, offshore wind has really given more options. 80% of our workforce in the east coast come from within an hour of our operational hub. so it's really opened up a world of opportunities for seafaring families like mine which didn't exist 15 years ago.

one day later, and the sea is calm. right, so this is my cabin, pretty cushy. have a look at this. so this is the lounge. sorry, lads! and this is the lounge. sorry, lads! and this is the lounge. sorry, lads! and this is the dining area. and let me tell you, the food is really good. let's see what's on the menu. jill? what is forte? it see what's on the menu. jill? what is forte? , , see what's on the menu. jill? what isforte? , , . ,, ., is forte? it is fish, chips and mushy peas. _ is forte? it is fish, chips and mushy peas, and _ is forte? it is fish, chips and mushy peas, and we - is forte? it is fish, chips and mushy peas, and we have i is forte? it is fish, chips and l mushy peas, and we have got is forte? it is fish, chips and - mushy peas, and we have got pork chops, bread—and—butter pudding and custard. film. chops, bread-and-butter pudding and custard. , ,., chops, bread-and-butter pudding and custard. , , one day later, and the sea is calm. this time we do get to the ladder.

it's quite a climb and this is just to the bottom of the thing. but there is bad news. so we have managed to get onto the turbine, but the crane isn't working, which means we can't get our gear up from the boat, which means we can't go up the turbine. but i can give you a sense of this, look at this. just how huge these wind turbines are. these monsters are almost 200 metres high, and each turn of the blade is reckoned to generate enough electricity to power an average uk home for a day. it's nice to know that your time and energy is contributing to the world running on green energy, which will be a better future for everybody. as we head back to humberside, we get a fantastic view. these wind farm can power up to! million homes, and i've almost finished

another even bigger one next to it. and there are plans for many more around the country. what's more, the wind revolution isn'tjust happening here in the uk, it's starting to take off all around the world. the world's leading climate scientists have warned that billions of people are at risk of chronic water scarcity. from northern kenya to the deserts of mexico, it is now a daily reality. we'll be hearing from kenya shortly, but first, the colorado river once ran through northern mexico. thanks to water usage upstream in the us, it hasn't flowed there for years. now in a unique cross—border experiment with the usa, the river will flow again for one summer only. this used to be water. for years now, it's been dust. the colorado river used to be

the lifeblood of this community. because of climate change, there's less water to go around. and most of the rest is used upstream for agriculture. antonia's mother blames the us using more than its fair share. but the us says its meeting its water commitments to mexico. with climate change, the whole region is becoming drier and hotter. in the nearby city,

police are responding to yet another heat—related emergency. authorities say it's mainly vulnerable people such as the homeless who are affected. medics told us that the sun gets so hot that their internal organs begin to cook. a total of 422 people in the state suffered heat—related illnesses over the summer. in one city, mexicali,

27 of these people died. meanwhile, the impossible has happened upstream. after a long campaign, the us has released 43 million cubic metres of water to fill the river this summer. it's a sight that she never thought she would see. for her, it came just in time. one month later, she died after a long illness. the river will dry up again soon if it's not replenished. both governments have committed to refill it, but that is not yet enshrined in law. a new generation can play in the river for now. but soon they too will have to take on the fight. there are few places in the world

where the consequences of the changing climate are as stark as in northern kenya. recurring droughts mean the land is so dry, some people spend their days simply searching for water. on the front line of climate change, a seven—hour trek brings something to drink. this grandmother is part of the turkana community, a million people who have lived off the land for centuries. life here has never been easy. but recent droughts have robbed these people of water, livestock and vegetation. now they are fighting to keep the only life they have ever known. translation: they claim it has changed, we don't get water- from underground anymore, because the wells are dried. i have nothing left. yet another desperate search where water used to be.

not that long ago, this dam was an important local water source for villagers and their livestock. on any given day, you would see cattle, sheep and goats here. as the rainy seasons became shorter and drier, this dam completely dried up, forcing local communities to walk further and further to find water to survive. livelihoods here are intrinsically linked to the local environment. droughts used to hit turkana every ten years, but in the 1990s, the frequency doubled, and in since 2017, drought conditions have struck turkana every second year. flash flooding can also strike here, with the power to wipe out entire herds. extreme weather events mean food shortages, rising poverty and insecurity. translation: when the drought came, it brought the animal diseases. - and we lost many animals.

now children go hungry because there is no milk. some herders say they are left with no choice but to travel long distances in search of food. sometimes that means crossing borders where livestock is stolen and violent conflict ensues. the people here did little to cause climate change, but they are bearing the brunt of it. you cannot mitigate, mitigate requires technology. but we can just adapt. but you see, because of this climate change influence which is increasing, day in and day out, it is going out of our hands. a donated water pump brings this community some relief. but it won't bring the rains that people here so desperately need. that's it for countdown to cop26. next week, we will be reporting from delhi on the challenge

of climate proofing our cities. for more in—depth coverage, go to the bbc news website and our brand—new climate page. i'm justin rowlatt, thank you for watching. hello there. with a mixture of sunshine and blustery showers today, it has been a day for chasing rainbows. this double rainbow was seenin rainbows. this double rainbow was seen in lincolnshire later in the afternoon as the showers whooshed across from the west. and a rainbow in the shetland islands, it has been very windy early on, first some wet weather sweeping eastwards across northern scotland, turning dry overnight. a few showers keeping going overnight, particularly developing light across southern england and wales, the wind off the english channel meaning temperatures

remain in double figures. with clearer skies, scotland could see four 5 . more clearer skies, scotland could see four 5. more showers tomorrow morning, but eastern areas dry, showers more likely out towards the west. the winds will not be as strong tomorrow, temperatures similar to today, and we have got rain developing by the end of the day, it will be a little cooler. the rain is coming from the steepening area of low pressure, meaning the winds are strengthening around the low as it moves into the uk. curl around this area of low pressure, we have rain moving northwards into scotland, rain continuing across northern england and wales. to the south, turning bright and breezy, dry for northern ireland, but for many a windy day, particularly around coastal areas, and combined with the rain, it will not feel warm at all for large parts of the country, no higher than 13. the

wetter, windier weather will pull away as the low pressure moves into continental europe, and high pressure builds in from the atlantic. wednesday is still cloudy and windy to start in eastern england with a few showers. the winds will start to ease down, and more of the country will see sunshine. with the lighter winds, a warmer day on wednesday, but we have increasing cloud and rain arriving into northern ireland by the end of the day, and that is the next approaching atlantic weather system that will bring a ribbon of rain to the north—west. higher pressure in the north—west. higher pressure in the south—east. that means we have a south—westerly wind which will bring some warmth and may be left temperatures close to 20 later on. —— maybe lift.

this is bbc news, i'm lukwesa burak. the headlines at 7... as the conservative party conference opens, the prime minister won't rule out a further tax increase but insists britain won't rely on immigration to boost the numbers of truck drivers to deal with the fuel crisis. the way forward for our country is notjust to pull the big lever marked "uncontrolled immigration" and allow in huge numbers of people. fuel retailers say supply problems are continuing in london and parts of south—eastern england but they suggest the "crisis is virtually at an end in scotland, the north and midlands". army tanker drivers are being deplyed from tomorrow —
