they worry the lack of ice will cause chain reactions across the arctic jason vox's an ice climatologist he says a drop in temperature could lead to all the problems in the region. this sea ice has in the last 40 years lost half of its mass half of its that miss and half of its area and this year after extremely persistent heat wave that affected siberia since since britain time that we've the fires are across northern siberia this part of the arctic is especially warm and so we see the sea ice effectively reacting to this extremely warm situation in it the north coast of siberia and it's a great concern because it's a very shallow sea and. underneath that 10 to 40 meter deep water layer is a sea bed that itself contains an enormous store of carbon i'm concerned that he or me of the sea waters can destabilize the carbon at the sea that so this area of open water it's releasing a lot of extra heat into the atmosphere and what that will do is perpetuate this condition of open water that's probably part of the delay of the return of the frozen sea surface. playland news. this is al jazeera

and why the lack of ice will cause chain reactions across the arctic here's more from jason box who's a climatologist and a professor at the geologic survey of denmark and greenland he says the drop in temperature could lead to other problems in the region the sea ice has in the last 40 years lost half its mass half of its that is and half of its area in this year after greenlee persistent heat wave that affected siberia since since time we've the fires across northern siberia this part of the arctic is especially warm and so we see the sea ice effectively reacting to this extremely warm situation to the north coast of syria and it's a great concern has it's a very shallow sea. and. underneath that 10 to 40 meter deep water layer is a sea bed that itself contains an enormous store of current i'm concerned that he or me see waters can destabilize the carbon see that so this area of open water it's releasing a lot of extra heat into the atmosphere and what that'll do is perpetuate this condition of open water that's probably part of the delay of the return of the frozen sea surface itse

and that heat is actually amplifying this disk lima change if you will it's warming the arctic even faster than the rest of the globe and melting ice even faster so the effect that has on the global large scale circulation is something that we're really trying to understand we're just having a few pictures of you with the team on the ground tell us about the practical challenges of working that a mormon. well we were there for the whole year and so we experienced for example the polar night when it's dark for 24 hours a day course it's very cold windy the ice is breaking up there are polar bears so you can imagine a different challenge almost every day and so the arctic is a challenge but you know we really persevered through those challenges to capture some of this these fantastic observations that are really going to help us make progress what happened with with the cove at 19 did that affect. the experiment or how you how you operate it out there again an example of perseverance it was a big challenge of course the code 19 made it very difficult for us of course to bring all thes

they're worried the lack of ice will cause chain reactions across the arctic just to get your bearings we've got a shot of the imagine you're looking directly down so that's the way out to the north pole you're looking at norway over there and around to rusher on that side the laptev sea is this little inlet if you like is the bay here this picture taken on september the 15th when the ice had retreated to its 2nd lowest level on record usually by this stage the end of a sort of the end of october the ice has actually come this far and hit the coast again but not this year but we heard from jason boxer who is an ice climatologist a professor at the geologic survey of denmark and green and he says the drop in temperature could lead to other problems in the region you see guys has in the last 40 years lost half its mass. and half of its area in this year after green leaves persistent heat wave that affected siberia since since time the fires across northern siberia this part of the arctic is actually warm and so we see the sea ice effectively reacting to this extremely warm situation in t
