From the tisch wnet studios at Lincoln Center in new york, megan thompson. Thompson good evening and thanks for joining us. A day after agreeing to reach a ceasefire in syria within a week, World Leaders met today to end the fiveyear civil war that has fueled europes migrant crisis and may have cost half a million lives. Diplomats from the United States, russia, turkey, saudi arabia, and iran are among those attending an annual security conference in munich, germany. Secretary of state john kerry criticized russia for bombing raids during the past four months backing syrian president bashar alassad, who the u. S. Wants removed from power. The vast majority, in our opinion, of russias attacks have been against legitimate opposition groups. And to adhere to the agreement that has been made, we think it is critical that russias targeting change. Thompson Russian Foreign minister Sergey Lavrov is skeptical of a ceasefire, saying its odds of succeeding are only 49 , while russian Prime MinisterDmitry Medvedev blamed western sanctions on russia after its annexation of crimea, in ukraine, for hurting relations. translated we have fallen into a new cold war. Nearly on a daily basis, we are being blamed for the most terrible threat to nato as a whole, to europe, to america, to other countries. Thompson rebelheld areas around aleppo, syria, continue to be subject to fierce fighting, as Government Forces try to retake the city. And a new report from the independent Syrian Center for policy Research Estimates 470,000 syrians have died in the war, almost double previous estimates. New york times reporter david sanger is covering the syria talks, and he joins me now from munich. David, a day after the ceasefire plan was announced, confidence in it doesnt seem to be very high, correct . It certainly doesnt. We heard Sergey Lavrov, the foreign minister of russia, say today that he thought maybe 49 . And somewhat sarcastically we heard secretary of state keri say later o, oh, hes that optimistic . I think mr. Keri has a higher sense of probable that this will work. But theres an awful lot, megan, that can get in the way of this. There are two part to this. The first part is humanitarian deliveries to the beseemed cities in syria. I think theres a fair bit of optimism that those will be stark, and the question is how long will they last . The second and much harder part of this is what most people would call a ceasefire and what they are calling for these purposes a cessation of hostilities. Even secretary keri has said this may only be a pause. The idea is give enough of a quiet moment to actually get negotiations going. Thompson it seems that as talk of this ceasefire have increased, so have tensions between the u. S. And russia. Is this just posturing, or is it part of something bigger . You know, it really is something bigger. Think of the different elements. We have the continued tensions and sanctions over ukraine. We have the increased russian patrols off the of the british coast, off most of europe, more Nuclear Forces being exercised. And i think here, the americans were taken a little bit by surprise at the speed at which the russians ended up entering that air war over aleppo, and thus gaining some leverage that the u. S. Right now does not have in return. Thompson one of the anothers that has caused tension between the two countries is this issue of military coordination in syria. Can you talk a little bit about that and if theres been any movement on that front. The United States has been very, very cautious about getting into coordination with the russians because they say, look, the russians are deceiving people about who theyre striking. Theyre striking many of the rebel groups aligned with the United States other ands who have been opposing assad, and saying that theyre just striking the two terror groups that have been designated by the united nations, the islamic state, and the alnusra front. But the coordination is going to be unavoidable over the next few weeks because theyre supposed to Work Together in a joint task force headed by mr. Kerry and mr. Lavrov, to pick out targeting. Theyre supposed to Work Together on the ceasefire, and theyre supposed to Work Together on the humanitarian aid. I dont know how you do that without something that approaches coordination, made all the harder by the fact that the United States, of course, back into the sanctions business against the russians right now. Thompson david, you can talk a little bit about the timetable, how this will all work on the ground. Well, megan, the way its supposed to work is that the humanitarian relief is supposed to begin within days, and secretary keri said today that the trucks are loaded up and ready to go. But thats a different thing than actually getting them into where theyre supposed to be. And the russians are supposed to be airdropping some aid. Some of the Big Questions is where they aired drop it and to which people . If a week from today we still see a lot of fighting going on, then youll know that this wasnt work the way it was supposed to. Thompson all right, david sanger of the new york times. Thank you so much for joining us. Thank you, mawg an. Good to be back with you. Thompson an Islamic Militant group linked to al qaeda is claiming responsibility for a bungled attempt to blow up a passenger jet over somalia earlier this month. Alshabab says the attack was intended as retribution for what it calls crimes committed by the west against the muslims of somalia. A suicide bomber blew a hole in the fuselage of a somaliowned Daallo Airlines jet, shortly after it took off from mogadishu on february 2. The plane had been en route to the african nation of djibouti with 73 other passengers on board. None of the other passengers were killed, but the bomber was sucked out of the plane to his death. The plane made a successful Emergency Landing in mogadishu. Pope francis is in mexico for a fiveday visit, his first as pontiff to the overwhelmingly catholic country. Thousands of people lined the popes route to the national palace, where he met with mexican president Enrique Pena Nieto today. In his public remarks, francis said mexican leaders have a duty to fight corruption and drug trafficking, and work for the collective good. The pope urged the countrys bishops and archbishops to do more to help migrants, and then celebrated mass at mexico citys massive basilica of the virgin of guadalupe, with hundreds of thousands watching on screens set up outside. More than 80 of mexicos 121 Million People are roman catholic, making it the second most populous catholic country in the world after brazil.

Thompson chipotle, the Mexican Grill chain, closed its 2,000 restaurants for four hours on monday for a National StaffVideo Conference on food safety. This after nearly 500 chipotle customers got sick last year after eating food contaminated with ecoli or salmonella. Regular inspections help keep restaurants clean and safe, but across the country, that job falls largely to local Public Health departments, many of which have limited resources. In chicago, food inspectors are improving their efficiency by analyzing data and communicating with the public on social media. Last week, i traveled to chicago to see how its being done. Thats tonights signature segment, and its part of our series on cities adopting innovative ways to solve problems called urban ideas. Reporter Mark Chmielewski is the executive chef at latinicity, a hip new eatery in downtown chicago. At this sitdown restaurant, bar, and at 10 food counters, customers can watch their sushi being rolled, burgers flipped, and burritos wrapped. But what they dont see are the steps behind the scenes that ensure the safety of their food. All stations have hand sinks. Probably the most biggest thing is washing your hands. All the fish gets iced down. Reporter chmielewski oversees systems and procedures to ensure that all the food served here is fresh. Everything up off the ground. Up off the floor. Reporter temperature is key. The u. S. Department of agriculture recommends hot food is served at at least 140 degrees. Cold food must be refrigerated 40 degrees and below. And dirty dishes must be washed in hot water close to boiling. Its paramount, to have, you know, great food safety with a place to prevent the public and your staff from becoming sick from foodborne illness. That can be devastating. It can shut you down. Fast. Reporter according to the centers for Disease Control and prevention, every year about 48 Million People in the u. S. Get sick from foodborne illness, from all sources of contaminated food. 128,000 are hospitalized, and 3,000 die. I think food safety is one of the core Public Health issues that we face. Reporter julie morita is a doctor and chicagos commissioner of Public Health. Her department is in charge of inspecting all 16,500 establishments that serve food in chicago. Close to 7,000 are classified high risk those where chefs handle raw ingredients and are thus more at risk of foodborne illness outbreaks. If we dont address and make sure that our food is safe, we will be constantly be dealing with outbreaks and challenges related to that, and so its really in our best interest to insure the safety of food so that we can do and focus on other areas that are important to Public Health as well. Reporter i followed one food inspector, Annette Grimes, as she made an unannounced visit to a restaurant on chicagos south side. Did you vacuum pack this, and wheres the machine . Because youre not allowed to vacuum pack. Reporter records for all shellfish must be kept. How about tags for the oysters . Reporter she even probes for clutter in the basement. The state requires chicago to inspect highrisk venues like this restaurant at least once a year. But chicago has had a difficult time keeping up. A 2012 review by the state found the city to be out of compliance with state inspection requirements. According to morita, theyre working to get back on track. The city has taken this very seriously, and so weve done some very creative and innovative things recently. Reporter the Public Health department hired more inspectors. Today there are 35. But thats still only one inspector for nearly every 200 highrisk restaurants. So the city turned to data analytics. Tom schenk leads a team of coders and data scientists who created an algorithm to predict which restaurants are more likely to have the most serious types of violations. This is an opportunity for analytics to come in and say, can we do this a little bit better . Reporter this is how it works. The program crunches 12 variables based on publicly available information. Things that seem obvious, like a restaurants previous violations, the length of time since the last inspection, how long its been operating, or nearby garbage complaints. And, the notsoobvious, like the threeday average high temperature, nearby burglaries, and whether the place is licensed to sell tobacco. Smoking is not allowed in restaurants. What we found is places with tobacco license were less likely to have these sanitation violations, which essentially probably means that theyre maintaining those high levels to make sure that they protect these licenses that are also very valuable to them. Reporter the number of burglaries in an area, what does that have to do with food safety . What we found was areas that have property crime around it, were more likely to have sanitation violations. Reporter explain to me how the weather has anything to do with whether or not a restaurant might violate a food safety regulation . One of things that matters the most around having food violations is whether or not youre able to maintain the temperature of your food. And so when the temperature goes up, sometimes its harder to keep those things chilled or cooled. And what this algorithm essentially does, is it takes this data, these different observations that we have, and essentially weights them in terms of important and how much weight and importance each one of these variables have to predict whether or not theres a critical violation at a restaurant. Reporter schenks team tested their program in 2014 and discovered the rate of finding violations increased by 25 . That meant, inspectors found violations about seven days earlier than before a week less of potential exposure for customers based on the algorithm, chicagos director of food protection gerrin cheek butler assigns the inspectors, also called sanitarians, to restaurants they must visit. The higher the coefficient the more likely there are to be critical and serious violations found at the inspection. So these are the ones that we would assign for inspection first. It updates continuously, so its always updating. So this has definitely helped us prioritize our inspections, put our sanitarians where they need to be. And so what we have found is that in the beginning of the year, we are finding that we have more critical and serious violations in the first quarter. Reporter that allows restaurants to correct problems early in the year. This is your inspection report. Reporter places like the restaurant on the south side, which failed its random inspection. Inspector Annette Grimes found violations with the dishwasher. We need to go to the three it fixed. Se this until we getse reporter and temperatures of some foods. Its only 118. Reporter the owners were fined. It has to be 140 or above. So all of that has been discarded and youre being issued a critical citation for having those products. Reporter the managers have one week to make necessary changes or face the possibility of more fines and inspections. Well make sure everything is taken care of as soon as possible. Reporter chicago restaurants are required to post their inspection report somewhere publicly, but its not like new york and los angeles, where restaurants get letter grades that are posted right in the front window. Chicago does make the inspection results public online, posting them on the web in a database searchable by restaurant name. In addition, the city has launched the app open grid where residents can find Public Information including restaurant inspection results. Chicago is sharing the code behind its algorithm so other municipalities can use it. Montgomery county, maryland, was the first to try it out. In a test, it found violations three days earlier than before. Besides the algorithm, the department of health also responds to complaints about restaurants. Most come through the citys 311 system, or twitter. A program called foodborne chicago mines twitter for messages about Food Poisoning, and often responds. So shes saying, Food Poisoning is not my favorite. And then we responded from foodborne chicago and we say sorry to hear that you were ill. The chicago Health Department can help. And then we give them the link. Reporter the link is to an online form asks users for more information about what happened. If the tweet checks out, the department of health sends an inspector. Of the nearly 4,000 tweets reviewed in the last few years, about 600 generated an inspection. At latinicity, which passed its last inspection with only a few minor things to fix like a leaky sink, executive chef Mark Chmielewski welcomes chicagos use of the new algorithm. But he hopes restaurant goers check the citys inspection reports rather than believing unverified complaints on social media. Thats a slippery slope. Twitter and social media, they wield a very mighty sword. And if someone, they just i had bad sushi at, you know, abc place. Is it really from there, or was it from something that they had for breakfast. They could do a lot of damage to somebody if its incorrect. Reporter as for the restaurant on the south side, during the followup inspection this past week, inspector Annette Grimes found all violations corrected, and the restaurant passed. Thompson for the first time in four months, natural gas has stopped leaking from a well in Southern California. The leak at porter ranch, in los angeles, began releasing methane and other compounds in october and caused several thousand residents to evacuate their homes. The local utility, Southern California gas company, announced on thursday that the leak was capped for now. But there are questions about the health and environmental effects, and the impact on Property Values downwind from the leak. Kelly mcevers, one of the hosts of nprs all things considered, has been covering the story, and she joins me now from los angeles. So, kelly, socaldeira gas says they have temporarily stopped the leak. Whats the state of the fix and what happens next with it . Well, the company that operates this gas Storage Facility says that the leak has been temporarily capped. What has to happen now is that state regulators have to go inspect that and make sure that it is a solid cap, and the leak will be sealed permanently. Thompson so how hesitant or concern read families about moving back in . Right, so more than 5,000 families left this area near where this gas Storage Facility is. We talked to many of them. Some people are fine with going back. Some people are ready to go back. Theyre tired of living in hotels at the expense of the gas company, of course. But some people are hesitant to go back. We talked to one family whose little girl got very sick, and it wasnt from the methane thats being released. Thats not what makes people sick, say Public Health officials. Its the other compounds that are inside a gas Storage Facility like that can make people sick. But it can do things like rashes, cause respiratory diseases and other explikses. So there are some families that just dont necessarily trust that this leak is capped and that the Health Effects from it are completely gone. Thompson i understand that once it is permanently capped, the assistance that some of these families have been receiving will get cut off in about a weeks time. Is that really enough time to make sure that everythings okay . Right. I mean, thats eight days that theyre given once everything, you know, again once regulators say this cap is done, its finished, and its no longer leaking any gas, theyll get eight days of assistance from the company. Its hard to say. Heres what publicca Health Officials and the gas company say. They say there are no longterm Health Effects from all of this gas that was leaking over the course of these months. So when people go back, that gas wonting leaking anymore, but i think the question that remains is what are the effects of the gas that was leaking during that time . And although Public Health officials and the gas company say there are no longterm Health Effects, there are other researchers that say we actually dont know. In addition to the methane, there was benzene leaking, and something called mercaptain, thats what gives us that smell that you know gas is leaking. That is what made people sick in the short term. Lut the effects of benzene over the longterm, len screen is a cacarcinogen, so researchers say we dont have enough information about this leak over this amount of time. Thompson what do we know about the Environmental Impact of the leak. We spoke to a researcher, and he said the amount of the methane being released is the size of a small country in europe. And a state like california that is spending so much money to reluc of duce its Greenhouse Gas emissions, and when that you are talk about Something Like methane, which is one of the worst Greenhouse Gas, this is a real setback. Thompson any sense of the Economic Impact in porter ranch and surrounding areas . Well, there are a lot of lawyers now working with families who live in the area who are concerned about that very fact. People are very worried about their Property Values. There are some families, like i mentioned, who dont want to go back, but if they dont go back theyve got to think about what to do with their home. Once the gas company is no longer paying the rent, where do they live . There are a lot of families questioning how are they going to recuperate value of their home in an area where people probably dont want to live, dont want to buy a new house in porter ranch. And so its a real concern. Thompson all right, mark zandi thank you so much for being here. Youre welcome. This is pbs newshour weekend, saturday. Thompson jimi hendrix is considered one of the greatest guitarists in rock n roll history. He was from seattle, but before hendrix became famous in the u. S. In the late 1960s, he had a following in london. Now, that city has turned his last residence there into a museum. The newshours Phil Hirschkorn has more. Before releasing his third and final studio album, jimi hendrix was living in london, playing venues like royal albert hall. In the summer of 1968, hendrix represented a topfloor apartment in this building. His girlfriend moved with him. Well, its quite strange, as you can imagine, 45 years on to be sitting in the same room you were sitting in when you were 22 years old. Reporter the apartment is now restored as it looked then colorful cushions, persian rugs, a victorian shawl hanging over the bed. Theres hendrixs turntable and vinyl record collection. He wrote songs on an acoustic guitar. His girlfriend said hendrix told her this was his first real home of his open. The building, in londons mayfair neighborhood, had good musical karma. Classical composer George Friedrich handle lived next door in the 1700s. Magazine photographer barry wents of wentzell visited hendrix in this apartment. He said i got the. I wonder what it would be like to jam with him. Hendrix moved back to new york in in 1969. He died in london at 1970 at age 27. The handle house trust spent 3. 5 million ren vaight the apartment and is making handel and hendrix in london open to the public permanently. Thompson and finally tonight, oklahoma experienced the 30 strongest earthquake in state history today. The u. S. Geological survey says the 5. 1 trembler could be felt throughout the northwest part of oklahoma and seven other states. Oklahoma had more than 900 quakes that could be felt last year. And the National Weather service has issued a wind chill warning tonight for nine states where temperatures will feel below zero. Officials in baltimore, buffalo, philadelphia, and new york city have declared a code blue, alerting emergency officials to prepare and help get the hoimless indoors.
