adrienne: high inside the arctic circle, the archipelago of svalbard sits on the frontier of climatet's one of the fastest—warming places on earth. yet, for most of its history, it's depended on coal for energy and jobs. this mine — norway's last — will now close next year. and this arctic community is shifting to a more climate—friendly future. ditching coal was the first step, and this power plant switched fully to diesel last year. when we run the diesel, it's almost half the co2 emissions. that's including the exploration and production and the refinery and the transport up here. it's still a fossil fuel, so why do that? diesel will be an interim period, just a step on the way towards more greener fuel. they hope to tap future fuels like green ammonia or methanol. this is a complete off—grid situation. the wind doesn't blow all the time, the sun is gone for half the year — so we need something in the background which can secure supply even in the darkest and coldest winter nights. to help stabilise power, they've installed one of europe's biggest batteries. here we have four batt

in the arctic circle. on the flip side, in the summer they get 83 days of sunlight the opposite happens. they have daylight. all the time without darkness. and that happens in in the summertime. and the reason why is because the earth is round it goes around the sun and it's also crooked. it sits on a tilt. so what happens is it works its way around the sun but again it's wobbling and it's tilting. so because of the way that it's tilted as we go into winter in the northern hemisphere, it's tilted away from the sun. so you can see that puts the arctic circle in darkness. and again, there it is for the next 66 days. >> oh my gosh, it's so fascinating. all right. elisa raffa. thank you so much. and thank you so much for joining me today. i'm fredricka whitfield, the cnn newsroom continues with jessica dean. right now >> i'm jessica dean in new york. and we begin this hour with breaking news. president biden making a major policy shift in the use of u.s. weapons and russia's war on ukraine after many months of

>> finland has history of conflict a period of the country is within the arctic circle.s a history of famine. just 100 years ago there were still cases where people made bread out of tree bark because that was the only thing left to eat. there has been a long-standing effort to ensure there is enough food. organizing work seven going on since the 1950's. it's a conflict at the country is surrounded by water on all key sites. could be hard to bring in supplies so you have to be prepared. when people have been doing this for decades it built this mentality of preparedness. it is not alarming as many may cmac the story or read the story, it's more comforting for a lot of people to know that they are ready in case something happens and they know exactly what to do. kriti: a terrifying situation and we keep a close eye in terms of how this develops them what this assistance in preparedness a looks like. we thank you so much for joining us this morning. i want to go to the other stories making news. we want to stick with the impact of united states. donald trump's picks for co

miles across, which is just mind boggling when you're there and you're you're very near to the arctic circle. we went about this time back in 2017 and and we canoe that river. i can use about 350 miles with him. the river is about 1100 miles long. so after i had done ten days with him in the canoe, another one of his friends came and did ten days, and another friend came and did ten days. and another, because none of us could take 40 days off of work like he was doing. so what? why was he doing this? why was he trying to recreate? why was he trying to canoe across this river or down this river? well, the river had been discovered by well, let's say it was traversed by a european explorer for the first time, and that explorers name was alexander mackenzie. and that's why the river's named the mackenzie river. but what he wanted to call the river was disappointment. river, because he had thought that river was going to take him to china. they were looking for the northwest passage. now, here's what's really interesting about the mackenzie river. it goes straight west towards china right? so yo

we're just a couple of degrees south of the arctic circle in a gold rush town whose big money days are probably behind it, a weatherbeaten hamlet that's grimmer and grayer than your picture postcard vision of alaska. the motto here inevitably is there's no place like nome. and that's probably true. this is the end point of the famous iditarod sled dog race. right now, we're closer to russia than we are to the rest of the united states. only about 3,800 people live here. so by lower 48 standards, this is a small town. around here, it's definitely the big city. and like any city, nome has seen its share of evil. maggie ivanoff: where'd sonya go? sonya? sonya? reporter: sonya ivanoff saw nome as a way station on the route to somewhere warmer. that's according to her best friend, timayre. she definitely knew that she wanted to go to hilo, that she wanted to live in hawaii because we were tired of the cold weather in alaska. and she was determined to make money and go to college. sonya came to nome from unalakleet, a native village 150 miles to the southeast. unalakleet's on a little spit.
