you've likely heard about the effects that climate change is having on our planet and specifically in the Arctic which is warming twice as fast but what will actually happen if all the face melted on earth when you and I drink water we drink non salty water  all the water in the world most of it is salty just 3% is not salty of that 3% you can't get the most of that because 70% of that 3% Frozen 30 million cubic kilometers of Frozen water. It's so much frozen water so much ice and if you want to that was a meter stick it would cover North America that's a lot of Frozen water people on land frozen water forms glaciers ice sheets permafrost send snow but the Arctic is largely ocean so there it takes the form of floating sea ice like icebergs and because it's in direct contact with warming Waters cic play the first to melt as global temperatures rise in fact this year NASA reported that the extent of Arctic sea ice was the lowest ever recorded for January February April May and June 2016 Russia right over the North Pole with no ice in the way that's good for certain shipping companies maybe but for the marine species the polar bear walruses the seals they don't have their own habitats they're all going away their melting out from under room and ocean animals like tells and normals aren't you to these changes either as the ice melts energy and oil companies are taking it as an opportunity to search further north for untapped resources process known as seismic blasting they shoot air explosions into the water in an effort to map the ocean floor and find oil of course this has detrimental effects the whole ecosystem of the Arctic Ocean also causing physical trauma and habitat relocation wells in terms of sea levels won't have much of an effect is because the floating ice already displaces roughly the same amount of water as it would produce when it melts so the net effect would be negligible furthermore at the majority of Earth's more than 5% is land-based and contains mostly an enormous ice sheets that cover Greenland and Antarctica where there are entire mountain ranges almost as big as the Alps complete buried in ice so what if all the ice on land mounts if all of this ice melts the ocean is going to have more posts is going to go up it's going to go up 70 meters that's a long way people half the world citizens live on sea coasts that's where Commerce action is so they're going to have to move where are they going to go and who's going to pay for it Tokyo New York hello Mumbai at Shanghai and Jakarta are all Coastal and happen to be some of the world's biggest cities even a small sea level rise of only a couple feet paws up to a trillion dollars worth of flood damage per year a rise of 10 m would displace more than six hundred and thirty million people nearly 10% of the world population at 25 M 1.4 billion people roughly 20% of humanity is left homeless and to visualize the full 70 meters the rising Seas which turn out most of the US Eastern Seaboard much of the West Coast the entire State of Florida huge areas of Asia including Bangladesh and much of northern China and create a new Inland Sea in Australia we have a lot of ice ice reflects sunlight space but there's a feedback mechanism one thing leading to another as the world gets warmer the ice melts as the ice melts it's reflecting less sunlight into space which lets the world get warmer still the sunlight is absorbed by the dark liquid ocean so is the ice melts the world gets warm turn the sea gets fresher currently the world's oceans are criss-crossed buy a set of currents that act like a giant conveyor the only constant is change that true about life and it's true about the climate the climate has been constantly changing since the earth was formed 4.6 billion years ago for example in just the past two thousand years we have seen the Roman warm. When it was warmer than today then came the cooler dark is followed by the medieval warm period when it was at least as warm as today then we had the little ice age that drove the Vikings out of Greenland and mo recently a gradual 300 year warming to the present day that's a lot of changes and of course not one of them was caused by during the past 400,000 years there have been four major periods of glaciation meaning that vast sheets of ice the good part of the globe interrupted by brief interglacial periods we are in one of those periods right now this is all part of the pleistocene Ice Age which began in Earnest two and a half million years ago it still going on which means that we are still living in an ice age that's the reason there's so much ice at the pole what's the next question I believe was the number  what role does ATP play in the current love warming tray  I really came this way of releasing harmful what's a between champion are you skeptical about Mormon why you so short with me what is an impact that we can expect from climate change play increase in temperature what can we do right now just look like a changing into a difference  I believe we came because of the elevator this happened to move it in the process of fixing it reducing on factory radio I think you return the first time high school first heard about it was information by so that they gave you what role does human play in the current level 1 is cars good releases carbon dioxide  what is your opinion on the fact that 95 gases water vapor and 5% of carbon dioxide why is climate change happening are you skeptical about global warming and wife research what are some of the impacts we can expect from climate change as of now we're currently in an icing wouldn't you think that meeting was actually recovering from my sister in fact the past couple of years we've gained more turn on the Pepsi use the right now to slow climate change a real difference hi Brian when was the first time you heard change  why do you think climate change is happening what role does human activity play in global warming alright you know what greenhouse gas is alright okay what do you think about the fact that 95% of greenhouse gases are water vapor and not carbon outside like everyone else thinks alright you know how what the what does suppose it percentage of scientists are that say that it's cuz of humans 3040 okay well what people claim it says it's 97% but what people don't know is that they're not from the world that's from like you win and that's what you say about what do you think I saw a 97% of the UN scientists say that global warming is the cause is caused by humans but if you actually look at it it's not for the world it's for just a un so then there's other people that might disagree with it some people only know about those 97% what do you think about that alright the next thing is alright I know you know this but we're in an ice age right now it's supposed to be cold we're in an ice age but so then what the Earth is just naturally heating itself up cuz we're getting out of the Ice Age just look it up okay apparently it's a thing I didn't know about it okay it's okay bye is there an ice age turn up like I don't know alright so what do you think we can do to help slight change climate change global warming the Metro take a carpool what are you
