the marathon has attracted more than a 1000000 roadside spectators if you because they've won the men's rights for the 2nd year in a row. running for israel to win the us. you're watching news from a reporter episode looking at how some of europe's ski resorts are coping without snow. and of course they'll be more news at the top of. the how the banks watch. closely. carefully.

to get. discovery. subscribe to. documentary on you tube. it doesn't look much like winter in germany. here skiers snowboarders and ski resort operators are suffering from the mild temperatures. others. shut down. their winter sports

activities and trying to keep one step ahead of climate change. the. snow is. still all of the ski lifts are in operation and all of the slopes are. fully booked it's one of the most popular north of the alps but unlike in the alps winters can't be taken for granted here at $670.00. right on the climatic snow line and studies show this line could rise even higher in the years to. bring.

his family. as far as the facilities are concerned hunter bag is certainly one of the most modern ski areas in germany. and i was kind of also invested in increasing our snowmaking capacity just to be able to offer skiing for 2 to 3 months again. she between. some $360.00 snow can and stand at the ready at temperatures of minus 2 degrees celsius or below they can make snow and secure the resort's operations throughout a normal winter but it's 3 degrees above 0 invented to warm to operate the snow

cannons so on a few of the slopes they're employing what's called a snow factory it can produce snow at 4 degrees celsius but environmental activists criticize the vast amounts of energy and water it consumes the resort operators won't say much about that and we can only film what's on view to the public the snow guns out of which fine snow is shot but not the technology behind them but one thing is crystal clear artificial snow secures jobs here so then we just got to if we didn't have it we could have just the christmas season go by your forgets to. park it in country we definitely wouldn't have had any snow just because the temperatures never dipped to minus 2 degrees the snow cannons need. this some comments karl-heinz runs one of the. schools he employs 70 ski instructors he hires some of them specially from abroad because people from

many different countries learn how to ski here. and his skis school is constantly expanding. and i tend. to trend towards learning to ski and going to ski school continues unabated all this happened. and due to the numerous snow. cannon's we can finally be assured there'll be snow sneezy hard which means i can assume that i'll be able to run my ski school for 60 to 80 days. that's something i can do before his condition rummaged. preserved for the defeat. these days his ski school is attracting lots of guests from the netherlands it's a 3 hour drive from vinterberg to the dutch border for many this is their 1st time skiing. because we're going to ski we're denatures beautiful

yeah and there are mountains so that's that's good to sleep yeah yeah it looks very nice it's built i didn't expect so much snow expect so much. so much people called her for the school holidays have started in the netherlands it's the weekend and there's enough snow most of the businesses here make over half their yearly income in winter. thanks when things get too busy the luke and family take refuge in their trailer. they're in no hurry to hit the slopes because they can't hear long term their trailer is cold weather proof the winters here are never really harsh. to this fear mood of the war it's gotten much milder there's a lot less snow than in recent years. often we were half submerged in snow. with. the retired miner has been coming here for close to 20 years it's just

a 2 hour trip from his home city of deuce book. but soon he may only be able to hike here because temperatures keep rising in the hordes of tourists are taking their toll on the slopes. nico blink man is also concerned rising temperatures are eating away at the blanket of snow covering the slopes during what should be the most profitable period of the year when at the moment it's still good for schemes if it rains answers for cost it could be that we won't be able to run a summer ski lifts due to the lack of snow cover. we hope that it won't come to that but it could happen. in the fight to save every square metre of snow on the slopes really begins in earnest when the tourists have returned to the ski lodge for the night johann is on to and his

colleagues prepare the slopes for the next day with their snow groomers. it's really pretty windy up here and i come down number 7. come down. ok. thank god of us there just for today it was really fall so the ruts are quite deep so you need to go over it. but can take 4 hours for one driver. software that works with data collected by g.p.s. lets your harness know just how much snow lies beneath his snow groomer. you must have just 70 to 80 centimeters played a shell that's ok. no new snow has fallen for weeks there's only what's been produced by the snow factory. thanks.

and. this is over snow from the snow factory and it's fishy and you can move it around easily because it's quite sandy for sure tales of body rolls right before the blade in a barnes together pretty well once we've gone over it and then you have a really good ski slope just a view of the 2 well johan is does his rounds the tourists enjoy some place ski fun the touch. weekly touch. the next morning the party's over on the slopes as well overnight the rains came and melted most of the snow leaving grass and mud in their wake but undaunted some winter

sports enthusiasts gather on the slopes where skiing and snowboarding is still possible place. i got told. i mean. at least the slopes johann is a groom to the night before are still open. to the however nico brink month slopes are pretty much snow free the ski rental business he runs on the side is also deserted. even one off day can cost him several $100.00 euros for cards when they're told last night it rained on fortunately and now it's raining again and. when are you really notice the sudden change because many davey's are to simply stay away so we

have lots of equipment on hand and we can't rent it out temperatures are forecast to remain above 0 for the next few days so there's little hope things will improve more and more ski lifts are shutting down but yulian papa vinterberg top weather expert is looking on the bright side the geographer runs his own weather service just for this region and operates about 40 survey stations. he believes the current mild weather has less to do with climate change and global warming than with natural fluctuations which have always existed. there didn't you don't actually much here we live in a climate zone that strongly influenced by the atlantic ocean to talk of what happens on the atlantic has a big effect on us. that means in winters where the atlantic is calm cold winters. vinter. he doesn't foresee warm weather putting an end to winter sports in the

central up plans any time soon via the action of it as it is we don't expect a repeat of this winter it's an exception it's warm and changeable phases of the next winter to be significant in colder and snowier that's what we expect will happen. and many inventive big share his optimism including nico playing the man still he's been making provisions for years and that along with the ski lifts and ski rentals he also runs a hostel the bookings from schools and clubs mean he's no longer reliant on holiday years who stay away if the snow does. so it's our view of the. winter like this one would be fatal if you didn't have a 2nd source of income. but most people here do. sure it's not nice and here and there it can be problematic when a winter like this happens. he's already preparing for spring

when the ski slopes are transformed into a mountain biking adventure park that also helps to make him less reliant on snow. for us all of us. used to be that a bad winter would bring you to the brink of bankruptcy existence. luckily now we've brought in a new so a bad winter isn't quite so critical. but sure when you're self employed and everything's at your own risk and winter like this can give us sleepless night all too often got a lot on. it started out special called. but now if he has another sleepless night he can just go night skiing that also brings in more income and more visitors in the short ski season. it's things like this that are helping people invent to keep their faith in winter sports in times of climate change.
