the trans alaska pipeline. and crossing the mighty brooks range of 1000 kilometer long mountain range that runs right across northern alaska. pathway along the route we had cold put little more than a gas station in the middle of the wilderness until the mid 1990 s. the dalton highway was closed to normal traffic anyone wanting to use it needed a special permit from the oil companies now truck drivers tell us they're encountering more and more tourists most come here in the winter to see the northern lights but they often underestimate the risks just beautiful as it is nice as it is it's not to me it's not worth it cause it's it is very dangerous you know and specially come i'm prepared just think about it you might have to walk you know 10 miles in this weather i thought people up here that got there and just have nothing no you know they have light jackets they have you know 10 issues and it's just not very smart it's tourists yeah pretty much. 'd 'd we

drive further into the mountains there's been a lot of snow fall in the last few days unusual or early october we stop off in wisemen a village that bloomed during the gold rush. everywhere you can see relics from the days when the dolphin highway and the trans alaska pipeline were being built in the arctic. just 14 people still live in weissman. where the freezers look like this and it's only october. here everything is pretty rustic. in his cabin jack recall is telling a group of chinese tourists about mine in the wilderness of how he shoots moose and bears in order to survive. it's a heavy caliber 8.6 millimeter does this is worth

a volatile mix like when it's submitted to vote gets the animal open and shop for a few days here oh let's move along and up when the all of the through the long the heart continues to pump blood to the long haul the blood he gnashing of the last. blood stand oh. but jack tells us the hunting's not as good as it used to be as we got out of 50 dangerous i travel plaza right by the lot about right but i looked at a lot of country but hardly anything in it. so it makes it hard to make sure what makes it art. jack came to wiseman in 1971 with his parents his father helped to build the dalton highway jack explains why there are practically no more moose up here in the woods that have now had 3 d. of snow here since 2000 for 1.4 meters now. it's the most especially when it melted on top of that for us there were breaking out of the snow to their chance that

cutting themselves up from that on the edge of the snow sounds like it was thick crust like it was killing. and it looks like this might be another bad year there's already too much snow for early october the air is too warm and too humid. the moose population doesn't have enough time to recover if deep snows occur every 4 or 5 years as they have in the last 2 decades. jack shows the chinese tourists some mighty moose and there's a popular photo motif. we asked these visitors what brought them here to the far north chinese people become richer on the reacher i know and that they want to see the whole sidles award. the best but i've never seen before and never seen so far i hope hopefully i can see our us at night. as they attempt to drive away we hope they'll get to see the northern lights tonight. the conditions are favorable.

the night sky is clear and full of stars. suddenly the heavenly light show commences. gradually becoming more and more spectacular. the next morning we continue our northward journey towards the arctic ocean following the trans alaska pipeline the road is icy for hours we find our way

across the brooks range which separates central alaska from the north slope region . at the northern foot of the brooks range lines the 2 like field station scientists from around the world come here to research the changes in the arctic jed tim manages the station he says they now have mosquitoes and snakes that conserve the winter here that's something new there's no denying climate change is real it's hard to argue with. that i i'm kind of in a weird spot because i you know i'm surrounded by science i grew up around science but i'm also a little bit of a redneck you know i like to like plants no machines but it's hard to argue with. you know with the research that i see in the glaciers that i see these disappearing firsthand. you know just how much warmer our seasons are it's pretty obvious jeb says it's one thing that it's getting warmer but want to

happen as a result of this will be the really big problem. there's enough permafrost up here that if that thick surface later that layer that 2030 meter layer melts. the whole north slope is going to drop about 30 feet or 10 meters i forget he says it hasn't gotten to that yet but things are getting critical he also stresses that he's no expert he suggests we talk to vladimir romanov's one of the world's foremost permafrost researchers roman hosty who advises governments and companies says the situation is quite clear. already have 35 years of measurements and during this period of time we started to is from a frost temperature about minus 8 now it's minus 4 on the north slope of alaska. from 20132014 we have new really strong wave of warming where all sides in interior laska show really

substantial warming. should this continue it could also have serious consequences for energy supplies around the globe as more and more of the world's oil and gas supplies come from the arctic. in the many areas distributional prices vary on the vendors some big chunks of pure almost pure eyes there and when this chunks of melting then surface of size developing very very many of them sources and there's many occasions already exist where this subsidence will reduce the oil structure infrastructure. heading north the trans alaska pipeline leads us out of the mountains and across the frozen arctic tundra a region of stunning natural beauty. then

we pull into a dead horse and the contrast couldn't be greater it's one big muddy mess and much warmer then further south. the dalton highway ends in a dead horse at its only stop the general store terry underhill is one of the few women in deadhorse she runs the store and like everyone here comes from the south she flies into work for 2 weeks and has 2 weeks off that's the rhythm of life here she tells us she's a big fan of donald trump like everyone here. we ask why obama made it so you can

drill up sure which killed us and he out lot a lot of stuff he put a lot of regulations on everything which made it to where they couldn't do anything and then went truck carolina lifted all the regulations and let us drill offshore again everything started opening up again so it was almost dead only it was like a ghost town. but now dead horse has been brought back to life and work has returned to. the workers' camps are fully booked. the huge containers stand on stilts like everything here that's built on or in the permafrost. because the land here lies just above sea level and in summer the upper layers of permafrost keep melting more and more gravel is spread to stabilize the ground. the question is how long will all this hold. all this infrastructure built to. extract material which will be.

very warm. through to thawing of frost and we'll make more and more problems water infrastructure and its design build to extract these is goods so that's kind of irony here. we board a private plane for supplies to get a better overview of the situation the oil companies won't let us film their operations even though we did produce them weeks ago over hundreds of kilometers huge plants come into view built into the slowly warming permafrost. all connected by the pipeline which runs through this swampy landscape. even offshore in the middle of the arctic ocean there are drilling platforms and bob our pilot tells us normally there'd be ice here but he says this year things have changed.

anyway for someone. like whatever you feel or they might or. might not. like everything you. say they are new. bit by bit and what i get out of the very unusual. year that i have not you know all over. bob says it keeps getting warmer here. we wonder if the instability of the ground isn't already causing problems. already on the infrastructure of your kids. yes but it's it's it's not official information. and they ask us not to talk. but yes yes they have problems and that's why i may do this selling things so in peace b.p.

is gone for more so. oil giant b.p. is withdrawing from alaska entirely even though more and more oil fields are being discovered and opened up for drilling our journey around the arctic circle ends here in the alaskan oil fields for some there the promise of a brighter future for others they're part of the problem. we've traveled thousands of kilometers through this immense isolated region a world that's warming more quickly than any other on earth. a world that will determine the future of humanity. the huge demand for wrong materials and climate change are making life more unpredictable by the day. should the permafrost and ice crust disappear our world will be a different one. and the knowledge acquired here over the generations is already

losing its significance here in the arctic. playing. both. places. please africa. south africa both 3rd world energy the initiative green cake the 4th environmentally friendly enough to generate katrina energy from florida hydro power. is always energy update. for. 13 years w's.

why are people forced to hide in trucks. there are many reasons. there are many cancers. and there are many stories. make up your body. made for mines.
