welcome to al jazeera america. i'm del walters. these are the stories we are following for you. president obama using the nuclear security summit to reiterate russia's invasion in crimea is a problem for the international community. compassion that i shared and their priority of putting our family first will help us get through this together. >> passengers on board of flight 370 dealing with the loss of their loved ones. and the death toll in that washington state mud slide continues to go up.

the final day of that nuclear security summit just ending in the netherlands. president obama speaking a short time ago, saying he is concerned about any further invasion by russia into ukraine. randall pinkston is in washington. and randall what was the president's message today? >> well, obviously in addition to talking about the progress that the u.s. and its partners have made in reducing nuclear weapons and trying to get some nations to give up their nuclear arms, this entire summit has been overlaid by the crisis in ukraine, and crimea. and the question of what will putin do next at the news conference at the conclusion of the summit, president obama was asked whether the u.s. can guarantee that ukraine, the baltic states and moldova will not be victims of putin's

aggression. >> there's no expectation that they will be dislodged by force, and so what we can bring to bear are the legal arguments, the diplomatic arguments, the political pressure, the economic sanctions that are already in place to try to make sure that there is a cost to that process, but i think it would be dishonest to suggest that there is a simple solution to resolving what has already taken place in crimea. >> so crimea a forgone conclusion that russia has it as long as it wants to keep it, however, if russia wants to return to the fold of the g-8, and the good graces of the international community, president obama and his allies can saying the troops should be pulled back, and russia should

return to diplomatic negotiations including its claims to threats to ethnic russians. the threat to economic sanctions could not be done without the strong support of america's european allies, especially germany which has some very strong economic ties to russia. russia supplies many european nations with much of their energy needs, so for them to get on board means that they could and would incur damage to their economies, but because of putin's actions, and you would have to say putin's misstatements about his intentio apparently they have managed to pull together this core of unity against putin and furtherer incurgence. >> phil ittner right you in kiev with reaction from that side of the story.

how are they responding in kiev? they are now talking about stiffer sanctions that the president said will hurt russia and members of the nato alliance as well, but that they are prepared to do that. >> yeah, i think those statements will be quite welcome here in kiev. the ukrainian government and many of the ukrainian people want the west to do everything they possibly can to punish russia. nobody really expects boots on the ground, but short of that they want the west to do everything they can, including assisting them with military aid, equipment, training things like that. i think it will be very interesting to see the reaction to president obama's statements about the east of the country, and that we have not seen this provocation and these aggressive acts that moscow says has been

happening against at ethnic russians, quite the opposite. >> and phil there were also changes on the ground in kiev as well. parliament dismissing the defense minister today. what lead to that? >> well, it was basically the fact that the previous defense minister, the guy that was knocked out today, delayed his decision to make an evacuation from the peninsula of ukrainian military personnel. many here say that took too long, and that's why we saw so many of these violent standoffs here in the crimean peninsula. so there is a sense that he waited too long, and his indecisiveness exacerbated things. they now have a new head of the

military here, and there will have to be some changes in the way that ukraine positions its military to deal with threat from russia. >> there is an age old argument in washington, and those that would argue military intervention in ukraine is needed, but what are they saying in kiev between the argument between sanctions and boots on the ground? >> well, they want as strong as possible sanctions. that is 100% clear. as far as boots on the ground are concerned, they know nato is not going to take on russia over ukraine they know that. but because they think that russia has grander designs on this country, and they are preparing for the possibility of a further aggression, and they

want help and weaponry. ukrainians think this is not going to end with crimea. that it is just the beginning. del? >> phil ittner thank you very much. the shooting suspect at the navy base in norfolk, virginia did not use its own weapon. he disarmed a petty officer and then shot and killed a sailor, security forces then fatally shot the gunman. the deadly mud slide in oso, washington state was predicted. scientists studying the hillside found the potential for catastrophic failure. that was 15 years ago. they say they took their findings to the army corps of engineers. officials say they are dealing with at least 170 reports of people missing. allen schauffler is in arlington, which is nearby, and

allen, the president expressing condolences for the families there. >> reporter: that's right, del, the president on his trip oversees talk about oso, washington and the huge landslide here. they did have searchers in that very dangerous slide zone. but they said no signs of life, and no new bodies discovered. there will be a lot more people, 150 or so out at the scene today. the president talked earlier from europe about the events happening here, and how the federal government will be helping out. >> i just spoke to the governor who swiftly declared a state of emergency. i signed that emergency declaration to make sure he has all of the resources he needs. my administration is in contact with them on an ongoing basis.

fema and the army corps of engineers have also been on-site. i would ask all americans to second their thoughts and prayers to washington state and the community of oso, and the families and -- and friends of those who continue to be missing. we hope for the best, but we recognize this is a tough situation. so that is an emergency declaration, that's short of a federal disaster declaration, but it will free up money and resources. fema will be on hand to help with the search and rescue efforts. we expect a team to be here to be deployed later today or tomorrow. the national guard will be out to help with all kinds of things, search and rescue, debr debris removal.

14 dead here, and emergency managers telling us this morning they will continue searching and they do expect that number to go up throughout the day. >> allen, are you receiving any more information coming out of the beefing, and also it is raining? >> yeah, there is the headline for you. it's raining again. we're expecting showers or rain for nine of the next ten days the last time i checked. that certainly didn't going to help at the scene. they are telling us this morning there are still very loose and shifting soils in that scene. they are asking people to stay out of the area. they don't want people in there freelancing in the slide zone, because there are areas that are still very dangerous. and that 15 million cubic yards of earth that came down, some of it is still coming down.

they are asking for people just to not go in there on their own, don't try to help, even though everybody feels compelled to do something. they are saying please just stay out, let us do our work, you could be putting yourself in danger if you go in. >> allen thank you very much. now to flight 370, families taking to the streets today in beijing. a wave of relatives gathering outside the malaysian embassy in the capitol city. their outrage coming just one day after officials concluded that the boeing 777 crashed into the ocean. they say authorities mishandled the crisis. and bad weather stalls yet another day of searching for flight 370. officials say the search might resume on wednesday. that weather coming at a bad

time. plane's black box has been 13 days of battery power left. reporters asking if there are any more clues to the crash? >> everything is urgent, but we cannot put pilots and crews at risk, or ships companies at risk. this is a mystery, and until we recover and positively identify a piece of debris, everything is virtually speculation. meanwhile jayden bureau's family was on board the flight and he thanked those for their support. >> we are heart broken this stage of their life has been cut short. they worked hard to reap the rewards of their retirement, so they could travel and spending time with friends and family. we are extremely grateful for the love and support from all of

our family and friends. we are grateful to the organizations and countries providing the extensive search preparations. now the thoughts go to the other families and crew on board the flight. our family appreciate all of the well wishes and prayers, but now we ask for privacy, and request that our wish for family solitude be expected during this heart-wrenching time. >> in the meantime the question remains where is the plane? the main clues are coming from satellite images. jacob ward is al jazeera america science and technology correspondent he took at look at the story. >> the information that malaysian authorities are using comes from a company that is a british telecom company that is one of the biggest commercial

satellite operators in the world. it offers free global maritime distress assistance. and it has done an unprecedented analysis. it's analysis that seems to provide a new picture of the final hours. all of the other aircraft communications systems stopped transmitting, they continued to receive pings from the plane, seven or eight in total between 1:11 and 8:11 when it disappeared from satellite. these are not gps enabled, they are just basic communication satellites so the company had to do some very complicated math to figure this all out. they combined elevation information with the time the signals took to reach the satellite. at that time they knew it was

moving north of south. then they figured in the doppler effect, the way that waves change form when the something observing them is moving. so they couldn't triangulate using multiple satellites, and they had to essentially make up a cruising speed. but they say other independent analysts have confirmed their conclusions. but the company also says there is no way to be more specific, this is the limit of the data, but it's convincing enough that the malaysian government is satisfied. no tangible evidence has been a verified or physically inspected yet, and we certainly don't have the black boxes. so this is the clearest sense we have, and we may ever have of the plane's fate. coming up on al jazeera

america, firefighters and other first responders say they can't afford to live in the town that they have to protect. they say this is another one of those issues of income inequality. >> president jimmy carter joins antonio mora >> my administartion has a very strong human rights element. >> his perspective on the conflicts facing the world in the state of america. on al jazeera america

>> these protestors have decided that today they will be arrested >> these people have chased a president from power, they've torn down a state... >> what's clear is that people don't just need protection, they need assistance.

>> wall street rebounding after two days of losses. reports showing consumer confidence hitting a six-year high in march. adjusted seasonably home sales increased from the month before. las vegas had the biggest increase. however, indications that home prices won't be rising as fast this year. and rising home prices and the difficult winter is being blamed for a drop in new home

sales, hitting a five-month old. houston is at a stand still for a fourth day now after 168,000 gallons of oil was dumped into the bay. houston's -- san francisco is getting to be too expensive even for the middle class. but there's a new program for first responders that could be closing the income gap. melissa chan reports. >> reporter: andrew ye was born in san francisco, raised in san francisco, and now serves san francisco has a firefighter. he also almost got priced out of living in san francisco. >> i went to preschool all the way to high school here, and everything has changed since

growing up. i think the tech boom has driven the prices pretty hard, and it is hard to even be able to rent in the city right now let alone buy a house. you have teachers, police officers, sheriffs, fire department, we want to be in the city that we work in. >> reporter: according to reports, the gap between the rich and the poor is growing faster in san francisco than in any other major city in the country. families in the bottom 20th percentile saw their salaries drop some $4,000 in the past five years, those at the 95th percentile saw theirs rise by almost $28,000. the medium income is $73,000. this group is discovering they can no longer find affordable places to rent or buy. with the cost of living sky high, some city firefighters and first responders have been forced to move hours away, and

that worries officials in this quake-prone city. >> it's really a question of when the next one hits, and when the next one hits, we want our first responders to be living in san francisco. >> reporter: city hall is offering first responders up to $100,000 in down payment assistance to purchase a home inside the city limits. the initial pool had enough money to help out about ten applicants. so andrew is one of the lucky few who have benefited from the program. >> a lot of them were cash offers, so i was just lucky to get a house in san francisco today. i just moved in about two months ago, so i'm doing a lot of little projects here and there on my days off. it's two bedroom, one bad small house on the hill. >> reporter: the city recognizes it would have to significantly

impact the program for any impact. andrew would like to see the loan assistance scheme grow so more public servants can also have the opportunity to live in the city where they serve. coming up on al jazeera america, there is history buried under all of that ice, some of it still buried from the ice age. and it may be spring, but it certainly doesn't feel like it right now. we'll be back with a very chilly national forecast and your headlines in just a moment.

welcome back to al jazeera america. i'm del walters. here are your headlines at this hour. a final day of that nuclear security summit just ending in the netherlands. the president joining the world leaders from more than 50 countries to discuss ways to prevent nuclear terrorism. the participate addressed the crisis in ukraine, urging european allies to take a stuff

stance against russia. eat challenge to obamacare, a private business heads to the supreme court. the founders of the retail store hobby lobby say it is against their religion to provide rt birth control to its workers. and words of comfort from the white house as searching continue to search for survivors from the mud slide in washington state. almost a quarter of earth is frozen over. under all of that ice are clues to our past, an ice tunnel in alaska is being studied now, and that is of course where we find daniel lack. >> how deep are we now? >> we are 60 feet below the surface. >> through frozen ground a tunnel back in time to when the earth last warmed up.

the ceilings bristle with an ingent plants and the bones of extinct bison. this was a fertile plane before the glaciers rolled in. >> we have a big ice ledge here on the left and over here. >> reporter: while other scientists come to see fossils soil and ice formed long ago, kevin studies engineering issues for the united states military, and how to plan for the effects of melting permafrost. >> if we can tease out that information that says what was the temperature prior to one of these climate horizons that we see, we would have really good information for the climate modelers that are working on that issue right now. >> reporter: work on a much larger tunnel has begun. research is helping alaskian communities cope with the

melting of the permafrost. >> the idea is not to scare anybody or set a -- you know, set out this -- this notion that everything is thawing and we need to stop burning gasoline. that's not what we're talking about. we're just talking about trying to anticipate changes. >> reporter: there's real alarm among scientists. a huge amount of carbon is trapped in the frozen ground, those plants and animal bones and that will be released into the atmosphere as it thaws. >> more thawing produces more greenhouse gases, increasing this greenhouse effect. >> reporter: when the trans-alaskian pipeline was opened, no one expected a changing climate, but they put the pipe on stilts to protect the tundra and forest. the way this pipeline is

constructed that prevents permafrost from felting locally, but what is inside the pipe, the impact of that on the world's permanently frozen ground, those are the larger issues that the government and the planet have to consider. ♪ well a major winter storm is working its way up the east coast. we have a stationery frontal boundary across portions of florida. you can see the miami area into key west, temperatures are going to take a major dive across the southeast. we have freeze warnings all across the southeast. little further to the north, well, the story is the snow coming down right now along i-95 from washington, d.c. into

baltimore, all the way down into the northern part of eastern north carolina. this storm is going to rapidly intensify tracking over the open water of the atlantic here you can see the center of the area of low-pressure, measured around 954 millibars, that's the equivalent of a category 3 hurricane. the winds with this system will be close to 60 miles per hour. so the blowing drifting snow will be a problem and the wind as well. we could see power outages across portions of the northeast. philadelphia right around 25 degrees, but the heaviest of the snow will come across coastal portions of massachusetts into atlantic portions of canada. again, blowing drifting snow the major concern. back to you del. loosely translated, the next
