conclusions, and there's no better example than the melting of ice, both sea ice, the layers of ice that form seasonally in the arctic, and around antarctica, and land ice, the major ice sheets, the continental ice sheets like the greenland ice sheet and the antarctic ice sheet. in both respects, both in terms of the shrinking amount of sea ice, for example, in the arctic at the end of a summer. the kind of trajectory that we're on leads to the conclusion that within a matter of a couple of decades, we may see ice free conditions in the arctic at the end of the summer. this is something that the climate models predict shouldn't happen for another 60 years, 'til the end of the 21st century, and indeed nature seems to be on a course that's faster, that's more dramatic than what the climate models predict. we are already observing and measuring a decrease in the amount of ice in the greenland ice sheet and the west antarctic ice sheet. now, the climate models have predicted that we shouldn't see that for many decades to come, and the key distinction here is if it's a land ice sheet, a land-based ice sheet, then when it

ice. before i became a polar oceanographer, whenever i thought about the arctic, i imagined icebergs, these big chunks of glacial ice. but really, it's seat dominates the arctic landscape. this ice freezes out of the ocean. it's made up of many individual pieces, which are called ice floes. sea ice in the arctic is constantly drifting, and over time winds and currents drive much of it into the last ice area. floes that enter nares strait end up being carried south with the prevailing current. this ice is on a journey of no return. we came from fort conger, and that took us all day, and now we have to go all the way across there. it's interesting to have a journey up here in this really remote place, where you think of these hardened explorers coming, and just have kind of regular people, like except for steve, you know, the rest of us are pretty much ordinary people just plucked out of life. like mike's plucked out of silicon valley, and bryce is plucked out of college. and you know, chris is plucked out of academia, and i'm just lifted up from my farm. it's 13 nautical miles to the other side of lady franklin bay. with the ice about to

arctic ocean losing its ice. let's go up here. climate models might say there's still a lot of old, large and thick sea ice here, but that's not what seeing. that we're not seeing any large floes here means there's no large floes in the arctic ocean either. the sea ice that's left -- it's young, ephemeral, and it's easily broken into small pieces. i'll get on the ice. this transition from old ice to young ice has occurred decades before we expected. it's telling us it won't take much for summer sea ice to disappear altogether. oh, all right. all right. to me, it's fascinating. the way i think about it is, the arctic ocean is white. it's white ice. if the ice wasn't there, if it all melted, the ocean would be dark, like super dark. an analogy i think about is, it's a hot day, and you're going to send your kid out to play. what t-shirt do you want your kid to wear? do you want your kid to wear a white t-shirt, or a black t-shirt? and we all know, wear a white t-shirt. and so what i've learned, is that the arctic ocean is kind of like the white t-shirt for the planet. there we go. hey. hi. how's it going steve? the kayak just slid bac

new research is revealing that human caused climate change is causing the arctic sea ice to decline andientists say the rapidly disappearing sea ice is devastating. ocean currents around the world resulting in warmer ocean temperatures. the effects are already on display in the waters off of florida's keys where see temps have been very hot this summer. >> carl's are not happy with level of hot water. they are bleaching a lot or die. >> while carbon dioxide naturally exists on the planet, a planet environmentalist say reducing fossil fuel use and production is critical to preventing even more arctic sea ice from vanishing. and kyle is here now with a look at what's happening, especially off of the florida keys and the map. there is kind of indicating to us just how warm it right? lighter colors are cooler temperatures, darker colors are warmer temperatures. and you know, they're talking about that in florida. how you do have the arctic's ice melting way to the north, right? and then it changes kind of the trajectory of the water in the way that things work. >> and unfortunately, we get

alcohol-related deaths rise at a faster rate among women than men, particularly for the elderly, and arctic sea ice falls to a record low this year as a result of rising global temperatures. we assessed the economic juggernaut that is taylor swift 's eris -- eras tour. >> this is "the pbs newshour" from weta studios in washington and in the west at the walter cronkite school of journalism at arizona state university. >> white house issued a statement this afternoon saying, "we have received confirmation that iran has released from prison five americans who were unjustly detained and has placed them on house arrest. the associated press reports iran's move is part of an agreement in which billions of dollars frozen in south korea will be released to iran. secretary of state antony blinken was asked about this late today. >> my belief is that this is the beginning of the end of their nightmare. in any respect, iran will not be receiving any sanctions leave, and in any instance where we would engage in such efforts to bring americans home to iran, iran's own fights would be used -- own funds would be

we have a record low and arctic sea ice extent, the lowest on record. the whole globe is experiencing change now. some climate scientists say there are simply not enough data to prove this, even though year after year the earth grows ever hotter. well that harkens back to the days when leading shipbuilders pronounced that the titanic was unsinkable until it did. back to you. yeah, tom, you mentioned the controversy surrounding the idea of climate change. obviously, there are some who who don't believe that climate change is at fault here and that it's really just typical weather patterns. well that's the thing. they're taking the viewpoint of weather that this is something that we have periods of weather that are warmer and periods of weather that are wetter and periods of weather drier. et cetera. et cetera. and they're basically looking at it from a weather viewpoint when in fact, most folks look at it and say this is a climate issue that goes way beyond the norma time., and that's what that climate scientist spoke to was sort of saying when you look

the warning, then the ice will recover we have seenin then the ice will recover we have seen in the arctic, a decades long production of seat in the recent decades. the ice is been more robust and in 2016, thatis ice is been more robust and in 2016, that is changed in the arctic and if you can reduce temperatures on earth and stop this warming, may be the ice will recover but if that does not happen than the outlook for the emperor penguin is certainly bleak. that is our science correspondent. more breaking news now. additional comments from president putin about prigozhin who is believed to be dead after the plane crash. putin said on the news agency that prigozhin had returned from a visit to africa on the previous day. that is an additional comment that vladimir putin is made and if i can reiterate some of the other comments that have come through from him in the past few minutes, he says that he brings his condolences to prigozhin�*s family and i'm that he was informed by russia's investigations committee and said the investigation will be investigated to the fullest extent and what we're looking at now is pictures fro

i have seen enormous changes around the world, high up in the arctic with every single year, less and less sea ice sheets, the coral reefs of the red sea, everywhere, i'm seeing what's happening to the planets, and this is a swim, a call to em po people around the world. i can speak to people around the world. the river ends in manhattan right next to the united nations headquarters. >> that's so true. >> and the importance of rivers. we have talked about some of the other bodies of water that you have conquered before, but rivers specifically, why? >> rivers are the arteries of the world. okay. if we want to have a healthy plan planet, we need to have healthy rivers. everything we flow into rivers, industrial waste, raw sewage, plastic pollution, it all goes down the rivers and then ends up in the sea. >> it's one of the reasons why in three of your four river swims, you have gotten seriously sick. you are taking in what we pollute and put in our rivers. >> yeah, well, i mean, it's an interesting story, the hudson, because at the source, it's absolutely beautiful. it's fresh clean water. >> the a

arctic. yes, there the sea drone was created to help ships, it is completely protected from fog and sand, it is able to fly in front of the court along the route, it assesses the iceon , it can mark icebergs, that is, the sea drone is the captain’s eyes that allow you to look beyond the horizon, one and a half meter waves calmly take off. we are in they showed the skeleton in the sea, that is, the first one something is a bathometer yes, from the descent of the bathometer to 15-30 m in depth in order to take water samples to do the second task - this is during search and rescue operations, if we saw a person, that is, a technical system a person sees us, then we drop boats to him. and if necessary. we can also speak from the boat to eat nearby. here. well, and so, in principle, and we completed the drone to determine oil slicks in automatic mode, we can determine them, and if we see oil slick, we can also sit down for a small fence of this oil slick in total , about 1050 teams gathered more than a thousand participants from all over the country at the arctic date competition, and the winners received funding for the further development of arctic solutions svetlana

ice-resistant, self-propelled platform. north poles, scientific expedition ship, academician, treshnik - this is here, helping to provide our country with scientific leadership in the development of the arctic for fishing in the northern sease after another, large freezers are laid fishing trawlers of the project st-192 to build such vessels is not possible for everyone with one engineering idea. buoyancy is not enough here, and stability and unsinkability are needed not only for the ship itself, but also for the project within the framework of which this ship is born . and here the skills of the management team are important . the main problems that our society faced in the construction of these vessels is the refusal of foreign suppliers to perform. let the adjustment work. uh, the equipment has already been delivered to order, nevertheless, the admiralty shipyard has successfully coped with the tasks, completed the test program and the ship, as i said, two individual ships in syria have already been handed over to the customer, and vtb bank is the main bank for the shipyard's creditors, members of the united shipbuilding corporation operate throughout the country, enterprises produce 80% of all ships in russia, but they

she says right now, arctic sea ice is at a record low, and the entire globe is experiencing change. and unless we can get a handle on emissions, the heating will continue to impact our lives. we do see what extreme weather does do to our area here in the bay area. of course, when we see our wildfire season. well, let's turn things over to roberta gonzalez right now who is tracking the weather changes are going through right now. roberta we still are being affected by the remnants or the remains of what was once hurricane hillary. you could see the activity still being fueled across las vegas, lifting up in a northerly direction and more activity over the reno and greater lake tahoe area. and we still have that area of low pressure that was anchored off the central coast for nearly two weeks now, lifting into the bay area. you could see the core is just about here because you have the counterclockwise rotation around that center of area. low pressure, and that is still drawing in some of that subtropical moisture from the south. now, meanwhile, it is still adverse as far as the weath
