311 homicides this year, a 59% increase over 2014. davis, who was deputy commissioner at the time of the rioting, says one reason the murder rate is up is this -- the looting of 30 pharmacies. suddenly 288,000 doses of prescription drugs were on the streets with gangs fighting for control. >> when they get tir hands on their stashes, then there's a competition for the geography that they nene to occupy to sell their drugs. and then from that violence has erupted. >> reporter: with the trials of those six police officers scheduled to extend straight into next year, davis says that he will treat a protest like a protest and a riot like a riot. scott, that is something he says e department did not do seven months ago. >> jeff pegues in baltimore. jeff, thanks. in the presidential campaign hillary clinton made news today

where more people are going to shop online than actually go into a store? >> i think eventually. but today absolutely not. if you look at the recent data from the commercrcdepartment, we know that online sales account for somewhere in the vicinity of 15%, 16% of total sales. maybe we'll drift up to closer to 20%. but you know, for now people still want to be in a physical location and spend their dollars there. >> i understand some of the retailers couldn't handle the traffic today. >> yeah. this was pretty wild because over the last few days outages at very big retailers like nordstrom or victoria's secret, this morning a big outagi at target. paypal down for a while. so technology not always perfect. i think the good news here is with the advent of apps and information we're smarter, we're better consumers. and the reality is we can now combat those algorithms thth are targeting g so beautifully by being infofoed. >> business analyst jill schlesinger, thank you very much, jill. an olympic champion has

york city, i'm scott pelley. >> announcer: this is the "cbs overnight news." welcome to the "overnight news." i'm jericka duncan. president obama and other world leaders at the international climate summit in paris got some words of warning from pope francis. on his way home from a week-long pilgrimage to africa pope francis warned that the world is in his words at the limit of suicide and that it is now or

limit obal warming. president oboba echoed those sentiments monday ininaris. >> we're here because we recognize the urgency of climate change and we believe that there's something that we can all do about it. as long as we work together. while the agreement that we seek in paris will be forged by governments, the ambitious targets that we set for ourselves are going to be reached in large part by the efforts of our scientists, our businesses, our workers, our investors. >> margaret brennan is at the paris conference. >> reporter: the world's two biggest polluters, china and the u.s., kicked off the climate change summit. >> it's our responsibility to take action. >> reporter: a pledge made as smog climbed to dangerously high levels in china. the goal in paris is to limi glal warming to 6.3 degrees

levels. but the terror threat is diverting attention. the president's first stop on french soil was to pay his respects last night at the bataclan theater, site of the worst of the paris attacks. france remains on high alert. a 120,000-strong security force is stationed across the country. riot police have been deployed in unprecedented numbers. on sunday 174 protesters were arrested for defying the government ban on demonstrations. former diplomatic security ant bruce tully has spent 40 years protectingngignitaries around the world. >> i think this is one of the highest-risk environments i've seen professionally in my career. there's so much threat analysis out there, not just from isis, copycats, but also because of the protesters for the conference itself. >> reportete environmentalists silently protested the ban on

worry about up here. >> so i will take the flare gun if you want to take the rifle. >kay. >eporter: this is polol bear country, where sarah and her german colleague norbert pirk are required by law to pack protection. the bears are more of a threat in summer when the meltback of their sea ice hunting ground has made them more desperate for food, eveneno the point of atatcking a research boat. but there's still a threat in winter, and it's in winter that this research must be done. >> this is basically your baby here, is that right? >> yeah. it definitely has to be running if we're going to get all the data. >> otherwise all this suffering is for nothing. >> reporter: every day@sarah comes out here to check instruments that are measuring a worrying trend. the release of greenhouse gases, which scientists used to think were safely locked into the frozen ground. >> the main thing we're looking at is the gas exchange with the

methane. but then we're comparing that to other parameters that we're measuring here. >> what, like temperature -- >> exactly. >> the weather basically. >> yeah. >> reporter: and the more those greenhouse gases are released, even from frozen places like this, the more warming there will be. >> there are concerns of that, yes. especially with the permafrost thawing that there is now old carbon t tt has become -- becoming available again to possibly be released into the atmosphere. we're trying to shine some light on this. >> in the dark. >> in the dark. >> reporter: sarah has been here a year and a half, working in these conditions because the arctic is, ironically and worryingly, where the earth appears to be warming most. they call it arctic amplification. it's hard to tell on a day like this, but the arctic is warming sooner, faster, and more than anywhere else. why y at's happening and w wt it

this little speck in the arctic has become the major center of climate research. >> you can't just measure one thing g d say oh, climate change, but t 's more about having all these monitoring projects and understanding how the system is working. >> reporter: another american, hannah miller, a 21-year-old from vermont, is here too. she didn't come for the skiing. she came to study how glaciers are shrinking. their melt water contributing to sea level rise. climate change decisions, she says, have to be based on science. >> the frustration comes in when climate change deniers use any of the uncnctainties to say thatat your argument is false. because you can have uncertainties and still have solid argument. >> hannah and sarah have joined a small, dedicated and brave community in svalbard. it's cutting-edge science up there on the edge of the world.

front-runner donald trump met with a large group of african-american religious leadads. but the planned news conference was canceled after some of the clergy were told it was a chance to endorse trump's presidential bid. a lot of them said they were there to listen, not to give trump their blessing. major garrett reports. >> reporter: baltimore pastor and activist jamal bryant questioned the wisdom of pastors lending their reputation to a campaign promotional flyer. >> why d d those who participate in black livesesatter look at the black church as a joke? and maybe it's because of these 100 preachers who have in fact prostituted the authenticity of the prophetic mantle. >> reporter: at least three pastororlisted on the flyer r ve backed out. others like mark burns, who supports trump's candidacy, admit many african-americans still have questions. >> this meeting is -- again, it's a 911 cry that he has to be able to address some of these

privately but he has to come out and address it pububcly. >> repororr: numerous other pastors scheduled to be at the meeting have released statements making it clear their presence is not an endorsement. one pastor said trump must address issues of racism and criminal justice reform. black lives matter protesters have encountered hostility at some trump r rlies, episodes trump said little about during or after. the cbs overnight news will be right back. i have asthma... ...one of many pieces in my life. sosohen my asthma symptoto kept coming back on my long-term control medicine, i talked to my doctor and found a missing piece in my asthma treatment. once-daily breo prevents asthma symptoms. breo is for adults with asthma not well controlled on a long-term asthma control medicine, like an inhaled corticosteroid. breo won't replace a rescue inhaler for sudden breathing problems. breo opens up airways to help improve breathing for a full 24 hours. breo contains a type of medicine that increases the risk of death from asthma problems and may increase the risk of hospitalization in children and adolescents. breo is not for people whose asthma is well controlled on a long-term asthma cononol medicine,

anonymous peace corps safety questionnaire obtained by cbs news, roughly 1 in 5 volunteers reported being sexually assaulted during their service. the report also shows nearly half didn't report the assaults. one volunteer wrote, "in reporting an assault i made myself a target." >> my thought was they're going to rape me, these men are -- these men are going to try to rape me. >> reporter: 23-yeararld peace corps volunteer denay smith had been in the remote dominican republic town of los mesquitos for eight months when in april two men with machetes forced her off this, the village's main road. smith fought them off and reported the assault to the peace corps. within a week the agency told her she was going home. >> and they also told me that my attack had occurred because i had been walking in my sight and as a volunteer it was my job to have been more proactive to prevent it from happening. >> reporter: more than 500

experiencing a sexual asasult in a little over two years. we spoke with nearly a dozen who estioned how their r rent cases were handled. they told us they felt criticized and were threatened they would be fired. five years ago the peace corps, a government agency, faced intense scrutiny over its sponse to sexual assaults. cocoress passed a law, and the change. >> i hired a nationally recognized leader in victims' rights to be our first agency's victim's advocate. >> reporter: that leader was kelly green. >> i'm getting phone calls and i'm getting e fails from returned volunteers that are in tears because they can't get the help that they need. >> reporter: cbs news found some peace corps employees attempting to limit the number of in-country counseling sessions for sexual assault survivors to a maximum of 6. in this 2014 e-mail a peace corps clinical psychologist said of a volunteer, "the need for ongoing therapy is an indication the volunteer was not a good fit for peace corps service."

for additional counseling a peace corps medical officer sent this e-mail saying, "i'm sure this will make no difference in her behavior." >> i pushed the agency to really do what they have the capability of doing, and that's what's so frustrating because they have the ability to do this and it is a choice not to. >> reporter: earlier this month the peace corps suspended her without pay for allegedly creating a hostile work environment. but green says s s was punished for standing up for the victims she was hired to protect. bonnie scott was a peace corps volunteer in albania. earlier this year she says s alerted the peace e rps one of its american officials was allegedly sexually assaulting albanian women. >> he was given the option to resign rather than face misconduct charges, which meant that everything would be covered up. >> reporter: shortly after the official senenthis e-mail saying

reasons, the peace corps fired scott for improperly filling out paperwork. >> t ty basically kicked me out ten days after they let -- >> reporter: inspector general reports show multiple cases of peace corps personnel accused in sexual assaults resigning ead of administrative action and then being allowed t treapply to the agency. a 2014 i.g. report warned the peace corps screening process for rehiring was not detecting past misconduct. one volunteer who admitted to violating the agency's sexual assault policy was later hired to work at the agency's headquarters in washington, d.c. >hat person's no longer employed by peace corps but i will also say that we are putting in place systems, mechanisms, to make sure that doesn't happen again in the future. >> person after person paints this picture of at least some percentage of the time there is what appears to be blaming or retaliatory responses to people

>> this is unacceptable to us, and we are trying to change the culture. our bebe indicator of volunteer satisfaction with our services is our sexual assault response quality survey. and 96% have said that they're satisfied with their service. >> reporter: that anonymous survey was sent to 183 people. just 52 responded. >> we have made enormous progress but it is a huge task and every single day we're providing better care. >> reporter: but denay smith feels only disappointment. >> i feel like peace corps failed me evererstep of the way. >> so far the peace corps says it has instituted more than 30 reforms regarding g xual assault ananworks to retrain employees whwhappear unsympathetic to survivors. kelly green, the peace corps victim advocate that's been suspended by the agency, is pursuing whistleblower protection but the peace corps disputes any claims it retaliated against her. the death toll continues to rise after holiday weekend storms socked the midwest and plain states. police in fort worth, texas

an international conference in washingtotoday will focus on a revolutionary technology that can edit getic mistakes. it's called crispr, and it could rid the world of cystic fibrosis, muscular dystrophy, and even hiv and cancer. norah o'donnell spoke with one of the pioneers. >> what is crispr? >> first of all, it's an acronym.

clustered regularly interspaced short palindromic repeats, a huge mouthful. you can see e y we use the acronym crispr. >> so i'm sorry. what's crispr again? >> reporter: geneticist jennifer doudna gets asked that question a lot. a researcher and professor at ucuc berkeley, doudna has become a spokesperson for a gene editing technology she's credited with developing. that mouthful known as crispr. >> i've heard it compared to essentially like a film editor slicing a bit of film. >> i would say that's a great analogy, yeah. >> how does that work, then? >> you think about a film strip and you see a particular segment of the film that you want to replace and if you had a film splicer you'd go in and literally cut it out and piece it back together. maybe with a new%clip. imagine being able to do that in the genetiticode, the code of life. you could go in and snip out a piece and replace it with something that corrects a mutation that would cause disease.

>> it's incredible. >> reporter: crispr hs generated immense excitement because it's fast, cheap, and can cut and paste genetic code with great precision. it used to take months or years to alter a single gene. now that can be done in a matter of days. >> could it end cancer? >> what i'm excited about there is the potential to use the crisper techchlogy to program a patient's immune system to recogngne tumor cells in a precise way. >> could it cure at some point virtually any disease? >> i don't know about any disease, but i think any disease that has a genetic basis is something that could be treated using the crispr technology. >> reporter: and imagine, doudna says we could expect to see clinical applications of crispr within the next few years. >> this is no longer science fiction. >> reporr: but alongside

of its perils, like embryo editing that could lead to designer babies. >> what is the dark side of this technology? >> one of them is of course making changes to human embryos which become permanent. so we're talk about sosothing that would affect human evolution. >> you could have an instance where a lab is creating lots of human embryos just for the sak of experimenting on genome iting on them, right- >> if you're asking me could that be done technically the answer is it could. could it be done with current regulations in place? certainly not in the u.s. >> or europe. >> or europe, right. >> there's still a lot of other countries other than the u.s. -- >> well, science is global and there are different cultural viewpoints on that kind of

scientists reported using crispr to edit the disease genomes of human embryos for the first time pn't experiment was a failure but it sparked concerns worldwide. >> i and my colleaguesave called for a global pause. >> reporter: doudna has long been vocal about the need to set ethical boundaries and is convening an international summit in washingtonl&d.c. >> what do you hope comes out of that? >> i think it would be great if we can at least get on the table the key issues. it's hard to imagine that there would be a consensus by all of the parties at the table about how to proceed but i do think the first step is to have that conversation. >> emanuel charpontier and jennifer doudna. >> reporter: the high hopes and high stakes associated with crispr have catapulted doudna into a rare stratum of scientific celebrities. last year she and her research partner received the$3 million

for this tuesday. for some of you the news continues. for others check back with us a little later for the morning news and "cbs this morning." from the broadcast center in new york city, i'm jericka duncan. the president warns it will soon be too late to stop climate change. we find evidence in china's pollution emergency and in the melting arctic. >> scientists say what happens up`here is what's going to happen to all of us. also tonight, deadlytorms in the southern plains and upper midwest. a court appearance for the suspect in the planned parenthood attack. and after black friday a new takeken the holiday calendar.

up a world of people to tart celebrating how we give as good as we get. >nnouncer: this is the "cbs overnight news." in paris president obama warned that the world is fast approaching the hour when it will be too late to save the planet from climate change. before the unprecedented global summit meeting mr. obama acknowledged the threat of terrorism, placing a tribute at one of the scenes of the recent attacks. then he told 151 heads of state and government that a deal to cut carbon emissions would be an act of defiance against terror. in our new cbs news/"new york times" poll, 66% of americans said the u.s. should join an international treaty to reduce emissions. when asked whether it's more important to protect the environment or stimulate the economy, 54 chose the

34% the economy. we have a team of correspondents covering this all ararnd t t world. first margaret brennan with the president. >> i've come here personally as the leader of the world's largest economy and the second largest emitter, to say that e ununed states of america not only recognizes our role in creating this problem, we embrace our responsibility to@do something about it. >> reporter: president obama came to office promising to slow climate change. today he pressed china and india, the world's other top polluters, to join him. and he offered to help poor countries convert to clean energy. the goal is toet 147 countries to reduce carbon emissions enough to keep global warming below 3.6 degrees fahrenheit. that's the level some scientists believe would prevent natural disasters like floods and droughts. president obama said those types of events are a risk to global

hosting the summit just two weeks after the terror attacks. >> what greater rejection of those who would tear down our world than marshaling our best efforts to save it. >> reporter: anyny agreement won't't be legally binding, and it doesn't require congressional approval. but republicans have threatened to withhold funding for a deal. scott, the white house argues that other countries won't cut back on their pollution unless america does so first. >> margaret brennan in paris tonight. margaret, thank you. the world's biggest carbon polluter is china. and right now its capital is choking. seth doane is there. >> reporter: the thick smog blanketed tiananmen square in a murky, hazardous haze. vels of the most poisonous particulates were more than 20 times what the world health organization says is safe. on a polluted day like today beijing is limiting activity at

sites. it is also encouraging people to stay indoors and encouraging more street cleaning. china launched a so-called war on pollution, which todayayt appears totoe losing. 2/3 of china's energy comes from coal. heating systems make pollution even worse. out with his family today, han wei told us the choking smog makes it tough just to leave the house. your son is about 6 1/2. how much do you think about him when you're out in this pollution? "i hope the government could do more so my kid could live in a better environment," he told us. "but i know it's not going to be done in a dada" the governrnnt here said that the smog was made worse by high humidity and a lack of wind. scott, we didn't see many people on the streets actually wearing these masks. some told us they didn't believe ey made a difference. others said they simply felt resigned to living amid the pollution.

capital tonight. seth, thank you. it's surprising, but another growinghreat to the environment is the earth itself. there is a spectacular amount of methane, one of the worst heat-trapping gases, locked up in the world's frozen tundrara that is, until now. we sent mark phillips above the arctic circle for tonight's "climate diaries." >> reporte it's a long way from paris to svalbard, norway, just 800 miles from the north pole. it's not just winter up here. the arctic night has set in. sarah strand, a 22-year-old from cacafornia, won't see t t s s again until mid february. and darkness isn't the only hazard. >> so i will take the sleigh down if you want to take the rifle. >> okay. >> reporter: this isn't just a scientific frontier. it's polar bear country. by law sarah and her colleague

protection. ththbears may b b more desperate in summer, when their sea ice hunting ground melts back more each year and where at least one bear has been driven to attack a research boat in search of lunch. but sarah and norbert are here in winter, braving the darkness and the cold and the bears, because their instruments are measuring a worrying trend that's happening now. thth is basically your baby up here, is that right? >> yeah. that definitely has to be run field goal we're going to get all the data. >> reporter: otherwise, all this suffering is for nothing. whwh the instruments are showing is that greenhouse gases that scientists used to believe were trapped forever in the frozen arctic ground are now being released. >> it's amazing we're lookt a gas e ehange with the ground carbon dioxide sxheth yain and we're comparing that to other parameters we're measuring here. >> reporter: what, like temperature? weather basically. >> yeah.

th arctic temperatures rising more quickly than anywhere else the gases may be escaping at an increasing rate. and the more greenhouse gases, the more global warming. >> there are concerns of that, yes, especially with the permafrost thawing. we're trying to shine some light on this. >> reporter: in the dark. >> in the dark. >> reporter: one of the most remote spots on the planet has become the center of research into the future of it. and it's not just because of what will happen to polar bears. the scientists say what happens up here is what's going to happen to all of us. and that's what's brought another american, hannah miller, up here too. the 21-year-old from vermont didn't come for the skiing. she came to study theretreat of glaciers, whose melt water, according to nasa, has contributed to a rise in global sea levels of around three inches in the past 20 years. what the climama change debate

>> the frustration comes in when climate change deniers use any of the uncertainties to say that your argument is false because you can have uncertainties and still have solid argument. >> reporter: a solid argument being sought in the frozen solid ndscape.

his first court appearance. he will face first-degree murder charges and perhaps the death penalty. three people were killed, including g policeofficer. nine were punded. barry petersen is in colorado springs. >> the initial charge against you is murder in the first degree. >> reportete robert lewis dear appeared by video link from the county jail, standing next to a public defender. he was asked if he had any questions. he answered@in a monotone. >> no questions. >> reporter: sououes say he went to the clinic on friday with a duffel bag ful of weapons and brought propane tanks in his car he could shoot and cause an explosion. when he surrendered, he reportedly said, "no more baby parts." that may have been a reference to videos filmed and edited by anti-abortion activists where they say planned parenthood officials talked of selling body partrtfrom aborted fetuses. an official from the group that includes the colorado springs clinic was among those in the

>> so ywhere from three up to seven. >> r rorter: dear lived in hartsel, about 65 miles west of colorado springs in a mobile home. he was described as reclusive, a man who never interacted with others and would rarely m me eye contact. for the people of colorado springs this is a time of mourning for the dead. university of colorado police officer garrett swasey, mother of two jennifer markovsky, iraq war veteran ke'arre stewart, who was there with his girlfriend. angelica llanca and her daughter alexis were in the clinic but separated wh the shooting started. angelica hid in a bathroom. were you afraid you would be killed? >> i don't know. to tell you the truth, all i wanted was my daughter. >> reporter: alexis was ang those evacuated hours into the siege. she is still traumatized. >> i can still hear the gunshots. >> now you can hear them in your mind? >> mm-hmm.

more charges will be filed in the next several weeks. as for the death penalty, scott, the local d.a. says that decision is several months away. >> barry, thank you. lala today chicago police officer jason van dyke was released on $1.5 million bail. van dyke is charged with murdering 17-year-old laquan mcdonald, who was armed with a small knife. video released last week showed the officer shooting mcdonald 16 times as mcdonald was walking away. a baltimore police officer went on trial today in the death of freddie gray, who suffered a spinal injury in april while being driven in a police van. william porter is chargedith manslaughter. five other officers will be tried later. the city has been gearing up for this case, and here's jeff pegues. >> the city and the police departnt need to do bebeer. >> reporter:r:evin davis,

department has been training for the trials and the unrest they could bring. >> we won't stop. >> reporte are you ready for what may comom during and after the trials? >> we are. >> reporter: davis acknowledges that wasn't the case in april. after freie gray's death the cici erupted. businesses were lootete and torched. police officers were injured. in the aftermath murders and violent crime spiked and officers were aused of not being aggressive enough. there were conceces that they were pulling back. did that happen? >> i think a more thoughtful way to recognize what happened for a couple months here is this police department had ptsd. >> you said ptsd. is that a politically correct way of saying that they were taking a knee? >> i think it's a correct way of saying that cops had anxiety. >> reporter: davis's predecessor anthony-bats was anthony batts was fired in july.

311 homicides this year, a 59% increase over 2014. davis, who was deputy commissioner at the e me of the ririing, says one reason the murder rate is up is this -- the looting of 30 pharmacies. suddenly 288,000 doses of prescription drugs were on the streets with gangs fighting for control. >> when they get their hands on their stashes, then there's a competition for the geography that they need to occupy to sell their drugs. and then from that violence has erupted. >> reporter: with the trials of those six police officers scheduled to extend straight into next year, davis says that he will treat a protest like a protest and a riot like a riot. scott, that is something he says the department did not do seven months ago. >> jeff pegues in baltimore. jeff, thanks. in the@presidential campaign hillary clinton made news today when chahaie rose asked her whether u.s. combat troops

isis in syria and iraq. >> i agree with the president's point that we're not putting american combat troops back into syria or iraq. we are not going to do that. this fight -- >> under no circumstances would you not do that? >> well, at this point i cannot conceive of anan circumstances where i would agree to do that because i think the best way to defeat isis is, as i've said, from the air, which we lead, on the ground which we enable, empower, train, equip, and in cyber space where don't forget they are a formidable adversary online. so what i want to say is look, we don't know yet how many special forces m mht be needed, how many trainers and surveillance and enablers might be needed but in terms of thousands of combat troops like some on the republican side are recommending, i think that should be a non-starter. >> it was a wide-ranging discussion.

sentiments monday in paris. >> we're here because we recognize the urgency of climate change and we believe that there's something that we can all do about it. as long as we work together. while the agreement that we seek in paris will be forged by governments, the ambitious targets that we set for ourselves are going to be reached in large part by the efforts of our ientists, our businesses, our workers, our investors. >> reporter: margaret brennan is at the paris conference. >> reporter: the world's two biggest polluters, chihi andndhe u.s., kicked off the climate change summit. >> it's our responsibility to take action. >> reporter: a pledge made as smog climbed to dangerously high levels in china. the goal in paris is to limit global warming to 6.3 degrees fahrenheit from preindustrial levels. but the terror threat is

the president's first stop on frenchchoil was too pay his respects last night at the bat bataclan theater, site of the worst of the terror attacks. france remains on high alert. a 1212000-strong security force is stationed across the country. riot police have been deployed in unprecedented number. on sunday 174 protesters were arrested for defying the government ban on demonstrations. former diplomatic security agent bruce tully has spent 40 years protect dignitaries around the world. >> i think this is one of the highest-risk environments i've seen professionally in my career. there's so much threat analysis out there, not just from isis, copycats, but also because of the protesters f f the conference itself. >> reporter: environmentalists silently protested the ban on their march, leaving their shoes in the square they had hopod to walk through.

poll shows that 53% of americans believe global warming is caud by human activity. 31% think natural weather patterns are the biggest factor. american experts are working in some of the world's most forbidding places to study the impact of global warming. mark phillips has the first installment of our series "the climate diaries." >> reporter: while world leaders may negotiating about what to do about climate in paris, but some of the most important research on the subject is being done about as far away from civilization as you can get. this is svalbard,, a collection of norwegian islands just 800 miles from the north pole. and it's where a young american climate scientist has come to try to unlock some of the secrets of climate change that have been frozen into this landscape for tens of thousands of years. sarah strand, a 22-year-old californian, won't see the sun again until mid february.

darkness isn't the only thing to worry about up here. >> so i will take the flare gun if you want to take the rie. >> okay. >> reporter: this is polar bear country, where sarah and her german colleague norbert pirk are required by law to pa prottion. the bears are more of a threat in summer when the meltback o o their sea ice hunting ground has made them more desperate for food, even to the point of attacking a research boat. t there's still a threat in wintererand it's in winter that this research must be done. >> this is basically your baby up here, is that right? >> yeah. it definitely has to be running if we're gqing to get all the data. >> otherwise all this sfering is for nothing. >> reporter: every day sarah comes out here to check instruments that are measuring a worrying trend. the release of greenhous gases, which scientists used to think were s sely l lked into the frozen ground. >> the main thing we're looking at is the gas exchange with the

methane. but then we're comparing that to other parameters that we're measuring here. >> what, like temperature -- >> exactly. >> the weather basically. >> yeah. >> reporter: and the more those greenhouse gases are released, even from frozen places like this, the more warming there will be. >> there are concerns of that, yes. especially with the permafrost thawing that there is now old carbon that has become -- becoming availab again to possibly be released into the atmosphere. we're trying to shine some lightht on this. >> in the dark. >> in the dark. >> reporter: sarah has been here a year and a half, working in these conditions because the arctic is, ironicallll and worryingly, where the earth appears to be warming most. they call it arctic amplification. it's hard to tell on a day like this, but the arctic is warming sooner, faster, and more than anywhere else. why that's happening and what it means for the rest of us is why

has become the major center of clclate research. >> you can't just measure one thing and say oh, climate change, but it's more about having all these monitoring projects and understanding how the system is working. >> repepter: another american, hannah miller, a 21-year-old from vermont, is here too. she didn't come for the skiing. she came to study how glaciers are shrinking. their melt water contributing to sea level rise. climate change decisions, she says, have to be based on science. >> the frustration comes in whehe climate chanan deniers use any of the uncertainties to say that your argument is false. because you can have uncertainties a a still have solid argument. >> hannah and sarah have joined a small, dedicated and brave community in svalbard. it's cutting-edge science up there on the edge of the world. on the campaign trail

front-runner donald trump met with a large group of african-american religious leaders. but the planned news conference was canceled after some of the clergy were told it was a chance to endorse trump's presidential bid. a lot of them said they were there to listen, not to give trump their blessing. major garrett reports. >> reporter: baltimore pastor and activist jamal bryant questioned the wisdom of pastors lending their reputation to a campaign promotional flyer. >> why did those who participate in black lives matter look att the black church as a joke? and maybe it's because of these 100 preachers who have in fact prostituted the authenticity of the prophetic mantle. >eporter: at least three pastors listed on the flyer have backed out. others like mark burns, who supports trump's candidacy, admit many african-americans still have questions. this meeting iss -- again, it's a 911 cry that he has to be able to address some of these

privately but he has to come out and address it publicly. >> reporter: numerous other pastors scheduled to be at the meeting have released statements making it clear their presence is not an endorsement. one pastor said trump must address issues of racism and criminal justice reform. black lives matterrotesters have encountered hostility at some trump rallies, episodes trump said little about during or after. the cbs overnight news will be rig (politely) wait, wait, wait! you can't put it in like that, you have to rinse it first. what's that, alfredo? no,that can go in. no it can't! what are you, nuts? that's baked-on alfredo. baked-on? it's never gonna work. dish issues? trust your dishwasher with cascade platinum. it powers... through... your toughest stuck-on food. better than finish.

a cbs news investigation on the peace corps shows nearly 20% of volunteers experienced some type of sexual assault. more than half of those say they suffered repeat attacks. what's more, many who came forward say they suffered retaliation from their bosses. kris van cleave reports. >> reporter: nearly 7,000 peace corps volunteers are currently serving in about 65 countries,

anonymous peace corps safety questionnaire obtained by cbs news, roughly 1 in 5 volunteers reported being sexually assaulted duringng their service. the report also shows nearly half didn't report the assaults. one volunteer wrote, "in reporting an assault i made myself a target." >> my thought was t ty're going to rape me, these men are -- these men are going to try to rape me. >> reporter: 23-year-old peace corps volunteer denay sith had been in the remote dominican republic town of los mesquiteos for eight months when in april two men with machetes forced her off this, the vimmage's main road. smith fought them off and reported the assault to the peace corps. within a week the agency told her she was going home. >> and they also told me that my attack had occurred because i had been walking in my sight and as a volunteer it was m job to be moree proactive to prevent it from happening. >> reporter: more than 500 volunteers have reported

a little over two years. we spoke with nearly a dozen who questioned howheir recent cases wewe handled. they told us they felt criticized and were threatened they would be fired. five years ago the peace corps, a government agency, faced intense scrutiny over its response to sexual assaults. congressssassed a law, and the agency's then director vowed change. >> i hired a nationally recognized leader in victims' rights to be our first agency's victim's advocate. >> reportete that leader was kekey green. >> i'm getting phone calls and i'm getting e fails from returned volunteers that are in tears becae they can't get the help that they need. >> reporter: cbs news found some pepee corps employees attempting to limit the number of in-country counseling sessions for sexual assault survivors to a maximum of 6. in this 2014 e-mail a peace corps clinical psychologist said of a volunteer, "the need for ongoing therapy is an indication the volunteer was not a good fit for peace corps service."

clustered regularly interspaced short pallin droemic repeats a huge mouthful. you can see why we use the acronym crisper wp. >> so i'm sorry. what's crisper again? >> reporter: she gets asked that question a lot. a researcher and professor at uc berkeley she's become a spokesperson for a gene editing technology she's credited with developing. that mouthful known as crisper. >> i've heard it compared to essentially a film editorr slicing a bit of film. >> i would say that's a great analogy analogy, yeah. >> how does that work? >> you think about a film strip and you see a particular segment of the film you that want to replace and if you had a film splicer you'd go in and literally cut it out and piece it back together. maybe with a new clip. imagine being able to do t tt in the genetic code, the code of life. you could go in and snip out a

something that corrects a mutation that would cause disease. >> that's incredible. >> it't' incredible. >> reporter: crisper has generated immense excitement because it's fast, cheap, and can cuts and paste genetic code with great precision. it used to take monthshsr years to alter a single gene. now that can be done in a matter of days. >> could it end cancer? >> what i'm excited about there is the potential to use the crper technology to program a patient's immune system to recognize tumor cells in a precise way. >> could it cure at some point virtually any disease? >> i don't know about any disease, but i think a a disease that has a genetic basis. is something that could be treated using the crispsp technology. >> r rorter: and imagine, dowdna says we could expect to see clinical applications of crisper in the next few years.

come fears of its perils like embryo editing that could lead to designer babies. >> what is the dark side of this technology? >> one of them is of course making changng to human embryos which become permanent. so we're talk about something that would affect human evolution. >> you could have an instance where a lab is creating lots of human embryos just for the sake of experimenting on them.. >> if you'ree a aing me could that be done technically the answer is it could. could it be done with current regulations in place? certainly not in the u.s. >> or europe. >> or europe, right. >> there's still a lot of other countries other than the u.s. -- >> well, science is global and there are different cultural viewpoints on that kind of application. >> reporter: in april chinese
