one i'm reading now, the book, "frozen in time" about some american aviators who crashed in greenland in the second world war. then the rescue mission that went after them and also went down, and another one that disappear, and they finally did rescue these guys, who lived for months in the tail of an airplane. a gripping story. then the second part is about an expedition to go back and find the people who were lost trying to rescue the original crew, and they located aircraft and all kinds of things. so it's a great story. in reading that, of yours you read the book jacket and he has another one, "lost in shangly law" about a mission that went wrong. was supposed to be a joy flight over new guinea in 1945 and the plane went down and the rescue was harrowing. so surviving in desperate situations is good reading for congress in an election year. i had the opportunity to meet recently -- i may mispronounce his name because it was just a -- david von dreel, lincoln rise to greatness, and our deputy whip put together a group of 15 of to us have dinner with him one night a couple weeks ago

narrator: during the 1950s and '60s, ambitious drilling programs in the remote ice caps of antarctica and greenland provided an impressive record of past climate, such as ice ages and warming events, going back hundreds of thousands of years. but these records only provided part of the climate's history. as a young man, thompson's interests lay outside the arctic. he set a goal -- to drill ice where no one had ever drilled before. in the polar regions at the time, there was a lot of competition, and no one was looking anywhere else. and so i'm thinking, "well, here's the rest of the world. why not?" and then, of course, if you start thinking about it, you realize that we got 6.5 billion people on the planet. 70% of them live in the tropics. and then you also realize a lot of the big weather phenomena that impact people -- el niÑo, monsoons -- those are tropical phenomena. and if you really wanted to look at the history of those, you need records from that part of the world. and i will never forget a rebuff when we proposed to drill the quelccaya ice cap. and it basically said, "the ice cap is too

they invited me onboard one of their flights over greenland. and after a few hours of flying certainly work up an appetite. >> few creature comforts in this plane, but it is simply business as usual, for the scientists that spend eight to nine hour as day, six day as week in the air. operation ice bridge began in 2009, after the satellite stopped functioning. but the next satellite i sat two, not slated to be launched until 2016, the air born missions started to fill the gap. but may also take measurements that are impossible from space. that allowed us to map the entire resolution, down to the bottom of the sheathe. >> that doesn't happen in the satellite? >> we couldn't do this from satellite, it would be extremely helpful, but we can't fly these radars from 600-kilometers off the surface. doctor, why is green land so important to this process? >> it is important because 8% of the world's ice actually sits on top of greenland. the thing is ice sheets act as a buffer, so if that disappears it will have major implications on the world's weather

actually i am reading now, mitchell zuckoff, "frozen in time" about some american aviators who crashed in greenland in the second world war. then the rescue mission that went after them also went down, and then another one disappeared. they finally did eventually rescue these guys who lived for months in the tail of an airplane. but just a gripping story. and then the second part of it is about an expedition to go back and try to find the people lost trying to rescue the original crew, and they low caked aircraft. so it's a great story. but in reading that -- of course you read the book jacket, and he was another one, "lost in shangrila" bat mission that went wrong. was supposed to be a joy flight over new guinea but the plane went down and the rescue was harrowing and took months. so surviving in desperate situations is good reading for congress in an election year. then i had the opportunity to meet -- i may mispronounce his name -- "lincoln's rise to greatness" and our deputy whip put together a group of 15 of to us have dinner with him, and they gave us all the book so i got the book for free,

however, in giant, the sea level rise equation has been ice in the major ice regions of greenland and antarctica. the latest science, again using satellite data, shows us that the giant is no longer asleep. are nowthese ice sheets losing mass. how quickly they melt over the coming decades will determine whether we have an additional one foot of sea level rise or up to four feet and perhaps even more. another major change in our climate rot about by human-induced warming is the increase in heavy downpours. this is clearly an area in which recent observations have been borne out our previous projections. our scientific understanding told us that a warmer atmosphere would hold more moisture, and we measured that, and, indeed, it is happening. we also predicted that the increase in water vapor would mean that more of the rain would come down in heavy events, and now we have seen that happen. some regions, like the northeast and midwest, have seen very large increases in the amounts of rain falling and the heaviest events. in the future, even areas that are projected to see decreases in to

jerry talked about the collapse of ice sheets in antarctica and greenland, and the other is the melting of permafrost, and massive releases of methane stored in the eyes for centuries, and a potentially additional burden on the atmosphere with respect to greenhouse gases that could actually accelerate the changes that we have already been talking about. >> following up along a similar vein, i worry about loss of sea ice in the arctic. we have seen by 2012 about a 50% reduction in the area of late summer sea ice, and about a 75% reduction in volume. one of the reasons that is a cause for concern is that that is a faster rate than the models projected with increasing greenhouse gases. it raises the possibility that while climate models are absolutely our best tools for projecting the future, creating this bound of possible outcomes, it alludes to things we heard from jerry and things we heard from tom that are sort of risks, worst-case scenarios, there are possibilities potentially outside of what climate models suggest that we need to be thinking about as well to protect our long-term co

sleeping giant however in the sea level rise occasion has been ice in the main major ice sheets of greenland and ant antarctica. both ice she is are losing mass. how quickly they melt over the coming decades will determine whether we have an additional one foot of sea level rise or up to four feet and perhaps even more. another major change in our climate brought by about human-induced warm something the increase in heavy downpours. this is clearly an area in which recent observations have been born out, have borne out our previous projections. a warm atmosphere would hold more moisture. we measured that and indeed it is happening. we predicted increased in atmosphere of water vapor and more rain comes down in heavy events and now we've seen that happen. some regions like the northeast and midwest have seen very large increases in the rainfalling in heaviest events. in the future even areas projected to see decreases in total amounts of annual rainfall are expected to see significant increases in proportion of that rain coming in very heavy events another thing we've seen is that the areas t

he was hoping to go to iceland or greenland, whatever it was originally, and -- >> permanently? >> yes, i think so. >> go and die there in a hundred years or fifty years from now, those were his plan? >> those are perfectly fine places to live, chris. >> people tend to love their countries and not want to leave it. banishment has never been an ideal career goal. >> he realized that otherwise he'd probably spend the rest of his life in jail. and i think it's natural that he would want to avoid that, even though -- >> okay, let me try something by a veteran journalist, one of the best there is, maybe one of the best in our business, you, andrea mitchell. wouldn't there have been a way without incriminating yourself to leak that information, not the paperwork, but the fact of the way we tap into people's information, their data, their electronic data, and online stuff. and why wouldn't he have done it that way? there's ways to get this information out if he wanted to do it and not get in trouble with the law. >> i think this justice department has been so aggressive at going after

all of the ghaish sheers on top of -- the ghai sheers on top of green shall the glaciers on top of greenland are now falling off the sea thus causing the sea rise? now, i want to flip it back to the senator from rhode island with this comment: in the hearing that we had of the commerce subcommittee in miami beach -- i chose miami beach. why? because it's ground zero. at high tide, they're already having flooding in the streets of miami beach. at a seasonally high tide that they expect coming up in october of this year, they expect constant flooding. and, as a result, we had the mayor of miami beach tell us about the efforts of them trying to redo the infrastructure to get rid of the water when high tides come in. what we also had testify was a scientist at nasa, a fellow who is a four-time space flyer. he left the astronaut office. he's back at the goddard space flight center in maryland. he is a scientist, and what he testified to us was not foreca forecast, not projections projee testified to us measurements of sesea level rise over the last 0 years. and for florida, the sea level rise, as

fast and then the arctic that part of the world the sea ice is shrinking and more disturbingly of the greenland ice sheet and the glaciers there are rapidly melting and parts of antarctica again can unload massive amounts of ice so you're saying that when there is a record breaking cold day does that mean that global warming isn't true brad while i mean i just keep getting these i mean it's it seems silly but it seems like this is kind of a counter argument that's pervasive is that record breaking days of climate change exactly is that it's climate it's not just hot and it's not just cold absolutely there are hot places and there are cold places to counterbalance that but overall when you look at the global average temperature we have the hottest decade on record happened just recently amazing and i can't help but on a federal level here i know i understand there's a lot of pressure on individuals as well there should be to calculate their carbon footprint and to be conscious consumers of course that that's very important i just feel like there is very little action being taken on a federal lev

sheetse greenland ice completely melt, our oceans will rise 25 feet. they have already increased six inches in the last 50 years. we are supposed to increase at a rate of 1/8 of an inch per year. once these ice sheets melt, we will not be able to get them back. you will lose cities across the world. host: jon huntsman writes an opinion piece in "the new york times." the gop cannot ignore climate change. the approach should be neither one of denial nordstrom is him. -- nor extremism. we are not inspiring confidence, especially among millennial's, who at least want an intelligent conversation on the subject. we need to plan for the impact of climate change at all levels of government. empower republicans leading those efforts to make decisions and investments that benefit constituents, the party, and the planet. denying science will only hinder the chance for success. he said it much more eloquently than i did in the opening statement. we need to turn the temperature down on this thing and talk about what is real, what are the right things to do. we also

will supply china with four hundred billion dollars worth of gas over the next three decades there greenland was twenty years in the making and was touch and go right up to the last minute parties katie pilgrim follow the final negotiations in shanghai. the deal was struck it sang high it paid for the why of it in the end that was had to pay for it yes i'm talking about these it said three big gaps from four hundred billions of feet you natural gas might to china that would change the face of the global gas industry not the way you know it we know that china was the bargaining. process again because my to it it seemed like a win win situation that is right now we know that china well it's got a one point three billion people population and they are and it's hungry a lot back to why the country has managed to grow at such a level for the last three decades that has come at a cost michael says we're certainly pollution the at it's very thick and that's because the country relies very much on coal for seventy percent of its energy from way towards a more free lead outsourced all the time that w

twenty thousand years and you've got six hundred thousand years of history with the ice cores out of greenland in the arctic i guess i just don't get to have an actual scientists to go so i don't see what else has scientists on the other you know you don't want to have what is over there in here and here is actually telling us exactly doesn't cause lung cancer and he's now telling us that the exact same scientists are now telling us that fossil fuels do i was climate i think that comparing climate you know deniers to holocaust deniers is insane that's completely unfair the whole earth was killed six million people if there is an extinction event you're talking seven billion people dying we really think there's going to be and i don't we don't carry their action rational design in the past hundred years the earth the u.s. has warmed one and a half degrees above the average for that yet fahrenheit that's not a lot of warming five percent more moisture our atmosphere that's massive there's not a lot i was just learning that climate change happens exponentially so may have been moving on with then

one i'm reading now is mitchell off's book first in time about some american aviators who crashed in greenland in the second world war. the rescue mission that went after them and another one that disappeared. they finally did eventually rescue these guys who lived for months and the tale of an airplane. the second part of it is about an expedition to go back and find the people that were lost trying to rescue the original crew. they located aircraft and all kinds of things so it's a great story but in reading that and of course you read the book jacket and he is another one lost in shangri-la or something like that. it's not the precise title but it's again about the mission that went wrong. it was supposed to be a flight over new guinea in 1945 in their plane went down. the rescue was pretty harrowing and it took months. people survived so surviving in desperate situations is a good rating for congress in an election year. i had the opportunity to meet recently and it was just eight david von drill rise to greatness. pete ross guimard deputy whip put together 15 of us to have dinner with him

just last year, we added greenland police chief mike maloney's name to the national law enforcement memorial here in washington, d.c. our state continues to grieve for chief maloney. unfortunately, chief maloney's death and the death last night of officer arkell reminds us of the dangerous work that our police officers do every single day on our behalf. they have no idea when they go out on nights, on weekends, on holidays when we are all safe at home with our families whether that next stop or whether that next response that they have to make will be their last. so we are grateful for the service of all of the police officers in new hampshire and across this country who every day go out and serve our nation and keep us safe. and certainly officer arkell represented the very, very best of our law enforcement community, and we're so sad today as we mourn his loss. and as we mourn the loss of officer arkell, i'm reminded of a quote that can be found at the law enforcement memorial in washington. the quotelllly sums this up. it is not how these officers died that made them heroes. it is how the
