ice radar so it can track ice movement as well as ice presence. >> so we're looking here at a screenshot from a radar that's mounted up in the bridge of the healy. >> this is a time lapse of images from that radar, as the healy navigates through ice. the ship is in the middle. >> the white, brighter areas show us where the ice is, and the dark areas indicate where there's likely open water. we use an image processing technique called optical flow, that allows us to work out how fast different bits of the image are moving at the same time. >> here's the same time lapse processed to show the ice movement as well as the ship's. >> we can calculate how fast the ice is moving over the ground... calculate the true motion of the ice. >> so from the ship's perspective we're moving past the ice, but from the ice's perspective it's moving a little bit too. >> exactly the ice is almost constantly adrift in the ocean. sometimes reaching speeds of 2 to 3 knots. >> how does this fit into your ice research? >> it's important to understand how the ice is moving dynamically over the ocean. that ties into

from november until may, ice makes the waters impassable without ice breakers. >> so after october, the hallie is not coming out here. >> no, ma'am. >> the maps are old and incomplete. even open water can be dangerous. >> so you are getting when you are going through here? >> right. north of nome there are a lot of blank spaces. >> melting ice is making the treacherous northwest passage, passable. if it becomes reliable enough for international shipping it could shave thousands of miles off the route of the panama canal, saving 30% of the cost as well. meanwhile, smaller ships are here in record numbers. but with just two aging ice breakers, the u.s. is largely frozen out of here for nine months. russia on the other hand has 41 ice breaks. many of them nuclear and they are actively building more. the u.s. has none under construction. >> coast guard admiral told me a couple of years ago, this was a ball game, the u.s. wouldn't be in the field, we won't be in the stands, we wouldn't be in the parking lot. we are last. >> you have to gain e attention of the american people. >> retired admi

nothing but ice cream so it's all emphasis on ice cream. and people hear about it and they think oh my gosh that's something completely new. that's different. >> what a novel idea. >> and yet they've been doing the same thing for 40 years. you can make an application to the church like that. a lot of things are changing in society and some catholics sort of drift away a little bit and things but as far as institutions are concerned or catholic schools it's pretty important to let people know that the institution believes the same thing that it did 40 years, 400 years ago, 2 this side years ago. >> it hasn't changed. that's a great analogy. we are going to talk about some of those things. we've got a list of the main tenants of the faith and we'll talk about that. what does it mean when we believe in the true presence of jesus, big topic. it's an ultimate big topic. hell, heaven, persian gulf tory, the priesthood. people often have questions about the priesthood. and then life. what is our belief in life and things of how to live out a chase

what will the ic workforce of the future look like in your view? how are we thinking about policies and processes for recruiting, retention, et cetera. and i would just add, are we getting -- how is recruitment going? are we getting the people we want? >> well, i will tell you that since 9/11, we have brought on a tremendous cadre of people. i just got back from a ten-day march in north africa and east africa. wherever i went, it's literally eye-watering to see what our intelligence people are doing. and the vast majority of these men and women have come on since 9/11. for me, a rather profound change in the community is that thousands have deployed to war zones multiple times since 9/11. that's had huge impact on the identification of missions in our workforce. and it continues to attract great young people to the intelligence community. i went to vietnam in 1965 and hardly ever saw a civilian. civilian employee or civilian contractor. they just weren't there. and that is very, very different today and that has had huge impact on the community. i

after two of those five ice ages, there was no ice anywhere on this earth. likef course, if anything that happened today, of course everybody would go nuts. the second thing is, it is in the same vein. if it is settled science, why can't they figure out what caused the dial 250 million years ago, or virtually, 90% of every living thing on this earth? man was nowhere in sight that time. thank you, sir. host: a couple of questions on the history of the research. guest: some of his questions are beyond the scope of my authority -- way beyond. [laughs] scientists do not argue that there was not climate change before humans. the more is that recent climactic changes we have seen set in motion and the more recent temperature trends dating back probably toward midcentury, the mid, if you look at the theresince then, i think is very widespread agreement in the scientific community that if you are looking typically of the warming trend we are seeing now, bear the very strong footprint of human activities. sure, obviously going back over millions and millions of years

-- about 75 gig a tons, 75 billion tons of ice each year. a block the size of a national mall the size of wash is a gigaton. from congress all the way to the lincoln memorial, four times as tall as the washington monument. imagine 75 of those ice blocks. that's what alaska's glaciers lose alone each year. the pace of melting is only fetting faster. getting faster. it's now twice it was between 1950 and 2000. twice as fast as it was just a little over a decade ago. and it's one of the reasons why sea levels rose by about eight inches over the last century and why they're projected to rise another one to four feet this century. consider, as well, that many of the fires burning today are actually burning through the perm a frost. this permafrost actually stores massive amounts of carbon. when it thaws or burns these gases are released into our atmosphere. over time. and that could mean that the arctic could become a new source of emissions that further accels global warming. triggering more melting more fires more thawing of the perma frost. ne
