the sea level rise that quite you know quite significant if all the ice in the antarctic ice sheet melted and we're not saying that this is going to happen and it's certainly not going to happen anytime soon and the scientists predict it could add up to 60 meters above sea level sea level rise as i said you know it's that will not happen but we are seeing on a year by year basis that the melting of the antarctic ice sheet and the melting of the greenland. are contributing you know an ever bigger amount to sea level rise i want to go that to you that he's watching us right now are set on a tweet as he is watching the show melting of ice is because of global warming which we can reverse this sounds confident is that even possible can we do it. because of the laws of physics the carbon dioxide which we are currently emitting into the atmosphere is going to stay there for a very very long time it's going to stay there in the oceans even longer so certainly we cannot reverse climate change global warning warning we're going certainly within my lifetime but what we can do is we can flow it we c

voters out sometimes the coolest new things can come from the worst of reasons at least that's what antarctic scientists and researchers are telling themselves up to a brand new island disappeared off the coast of the south pole this summer thanks to the ice melting as you can see in this picture. temperatures of climate change yes the melting of 2 major glaciers the waves on the pine island on the antarctic peninsula have revealed a brand new never before seen uncharted island that had been long buried under the ice of the glaciers well the island itself is just 350 meters long that didn't stop researchers from naming it after the ever powerful norse goddess of the earth. so happy birthday so why would glad to have you with us even though some of the worst of circumstances. that i got to say about deserves row pre-debate remember everyone in this world we are not told that we love them up so i tell you all i love you. and i'm of the people are watching all those hawks and have a great faith. in the united states presidential candidates debate the future of the us and the world . max keiser a

affect climate for example the humble of current brings cold water teeming with nutrients from the antarctic to the galapagos islands for 6 months of the year. they feed the tiny plankton and algae that form the base of the food chain providing sustenance for swarms of fish and also for the marine in quanah the only lizard that lives and forage is in the sea. on land meanwhile life in these months is hard there's hardly any rainfall wildlife including the galapagos giant tortoises have to embark on pair. journeys in search of food but in the other half of the year food is available in abundance that's when the wet season comes with the panama current bring in warmer waters. this current isn't nearly as rich in nutrients so much of the island's marine life heads off to colder climes aquatic animals that remain have to make do that finally climate change is taking a toll on ocean currents exactly how is the subject of intense research. as we heard ocean currents are critically important for marine life cold oxygenated currents are a source of life under water. but sometimes the local ecosystem

but one antarctic environment is surprisingly stae, the ocean.ut it's cold, -2 ° gratefuc. >> it is the coldest place on earth. temperatures are very, very stable. it is actually very difficult to fution at freezing temperature of seawater because everything goes slowly. they optimized their metabolisms for that temperature. anythingever seen warmer than that in millions of years. justin: her team is studying how these animals naged to survive and breed in such cold water. like everywhere else in the world, the antarcticnvironment is changing. some places, the water is already wming. a huge challenge for animals that have never experienced the change. some of the incredibleim antarcc s are in this tank. a marine biogist from you have been studying these animals for years. >> they have proteins inside of them that keep themee from ng. they have different red blood cells that are not red. they have mpensated for the cold, so they can go about their daily lives and thrive in an environment most animals would find stressful. how long these expert mar

west coast of south africa which quite unusual that i'll let you get out that was a feeling in the antarctic and with picking up a lot of juvenile whales this year 202019 hanging around the south african coast that are feeding right in shore in falls by a really interesting occurrence fast it gives us an opportunity to study the feeding behavior and the sounds and making where it's communicate using operad to focalize actions from clicks to whistles and of course songs each is associated with a specific type of behavior. comparing recorded here to that recorded in africa gives researches insights into which populations move through different areas so we were quite surprised when we 1st recorded come in in force by because i had a transaction there to look at dolphin distribution because hamburg was only strongly associated with my making behavior in these animals and around africa mating happens at the tropical areas equitorial west africa and of mozambique on the east coast around cape town and we should just be migrating past although we are aware of animals and summer months feeding as we

that means stronger storms, more storms, heavier rains and sea ice for the arctic -- record antarcticgoes into higher sea level records. that has had global impacts not just around the world but around our country as well. arctic heat and fires, above average fire activity for alaska, siberia. extreme rainfall, wettest 12-month period on record. dorian slowest moving cat 5 storm. record european heat, seven countries. of course australia's wildfires hottest and driest on record our climate is changing. >>> good morning. i'm meteorologist kari hall. we're seeing the storm system that's been over southern california still bringing parts of the south bay unsettled weather so we will still have a slight chance of rain mostly south from san jose on southward today. elsewhere mostly sunny sky and temperature reaching into the low 70s. a few clouds in the mix and some low 70s going into the end of the week. this weekend a widespread storm arrives and brings in some off and on rain as well as chilly temperatures. >> that's your latest weather. guys. >> thanks, al. >> mr. roker, thank you. jus
