narrator: these samples are shipped to noaa's lab in boulder, colorado where they are analyzed. in each sample, we measure carbon dioxide, methane, carbon monoxide, hydrogen, nitrous oxide, and sulfur hexafluoride. we'll take air from the bottle and send it to three different instruments. this is the one used to measure carbon dioxide. it's interesting -- the way we measure carbon dioxide is by absorption of infrared energy which is the same principle as the greenhouse effect. so we're using the same property of the gas -- how it affects climate -- to actually measure it. then at night, we connect these suitcases that contain flask samples collected by aircraft. come back in the morning and they're all measured. combined, ground samples and aircraft -- up to 100 a day. narrator: from these hundreds of thousands of air samples, noaa has compiled a comprehensive database of climate-changing gas concentrations over a long period of time. their findings are consistent with those first discovered by david keeling. in the 1950s keeling's first measurements showed co2 at the level of 3

but yet this fascinating study in here about these groups in colorado, one in boulder, one in colorado>> right, what happened is he got a bunch of liberals liberals in boulder to talk about climate change, same-sex relations and affirmative action, just the liberals together and had them talk to each other. and as they talked, they got more and more to the left. we did the same thing in colorado springs. we got conservatives people who tend to like vice president cheney together to talk about exactly the same issues, and as they talked they got more and more to the right. so what happened is before -- >> how do you get more to the reist dick cheney? ( laughter ). >> with well we didn't ask are you to the right of dick chain ?e we asked about climate change. before they talked in grew like-minded they could deal and talk to each other. but when the colsprings people talked only to the colorado springs people, and the boulder people talked to only the boulder people, it was it was as though they lived in different countries. >> jon: when they first got together, they were not stridently

we got people from boulder, colorado, pretty liberal territory. we made sure they were liberals by the way, to talk about climate change same-sex relations and affirmative action just in small groups. we took their anonymous views before they start to talk and then anonymous views after they talked. and what happened was that the diverse views relatively diverse of the people of overhead on those three issues, they became much more extreme and unified as a talking to each other. though the group ended up being much more cohesive and unified and left than the individuals before they talked. we did the same thing during the same period in colorado springs which is a conservative place. on exactly the same issues. they also became much more cohesive, much more confident and much more extreme, meaning more conservative than they were before. so the quote boulder people flipped to the left to colorado springs people flipped to the right. they both lost information in the sense that within colorado springs and boulder there were diverse issues on the vi

so, one bit of work we did experiment in colorado and got people from boulder colorado, pretty liberal territory we made sure they were liberals by the way to talk about climate change, same-sex relations and affirmative action just in small groups from boulder and we took their own honest views and headed into the prey to a verdict and took their anonymous abuse after they talked and what happened was the diverse views that they had on those three issues became much more extreme and unified as a result of talking to each other so the group ended up being much more cohesive and unified and left standing individuals before they talked and we did the same thing in the same period in colorado springs which is a conservative place and they also became much more cohesive and much more confident and much more extreme meaning more conservative than they were before. so the people flipped to the left and afflict the flipped to the right and they both lost information in the sense that within cover springs into boulder there were diverse issues that kind of fell apart the diversity as a result

so one bit of work we did experiments in colorado and got people from boulder colorado, pretty liberal territory we made sure they were liberals by the way, to talk about climate change, same-sex relations and affirmative action. just small groups from boulder and we took their anonymous views before they started to talk talk, had been deliberate a verdict and their anonymous views after they talk and what happened was the relatively diverse views on those issues became much more extreme and unified as a result of talking to each other so that group ended up being much more could he said and unified and left than the individuals before they talk and we did the same thing in the same period in colorado springs which is a conservative place and they also became much more cohesive, much more confident and extreme meaning more conservative than they were before so they flipped to the left and the right and they both lost information in the sense that there were diversities on the issues that kind of fell apart as a result of the discussions about like-minded people and i think that is a cl

in term of the al assad base bits the size of boulder, colorado.ective is helpful. they're very random. they're not targeted. they're ricky but it is a very big area. and it is not just u.s. troops there. it is iraqis as well. >> we heard barbara starr report a little while ago that the penn is about to sell to the iraqis battle tanks, sophisticated weapons. how concerned are you that the iraqi military might simply abandon these as they've done over the past year or so. and they wind up using military sophisticated u.s. military equipment. >> i think what you saw when isis first made its advance, parts of the iraqi army did melt away was really a wake up call. for the government, the political leaders and the military leaders and its army. since then we have advisers on the ground helping get them equipped. they know how serious this fight is. this has been an ongoing process of getting them women's they need. they have stepped up? have pushed isis back in some significant places. >> very quickly. the democratic senator from new jersey, the former

. >> another thing you found in the book, specifically in colorado with a group in boulder, you had political issues and you muted out these hot button issue you found when you put liberals together that the group would increase the based. >> yeah, i think this little study, which as you say in colorado reflects a lot of things that are happening around the world. we put a bunk of liberals together. and when they started to talk, we asked them anonymously their views with some diversity, and some were extreme, some not after short conversations almost all of our groups got more extreme more unified so while they could talk to conservatives more and have some commonty, afterwards they just didn't. we did the same thing in colorado springs on the same issues and internal discussions just one another shot them far to the right pop so when we ice lited the groups of people they ended up after the fact so far from each other, it was almost as if they were living in different worms. and before they constructive discussions would have before far more possible. >> is on both sides. from the time we a
