Margaret brennan on what she will do for her country. This is the cbs evening news with scott pelley. Captioning sponsored by cbs pelley good evening. The world is mobilizing to help the philippines, but just a trickle of food and water and medicine has reached the victims of typhoon haiyan. Today, president obama phoned the philippine president begnino aquino, promising additional help. About 100 u. S. Marines are already on the ground, as many as 2,000 more are expected. The Aircraft CarrierGeorge Washington should arrive on thursday. Aquino said today the death toll may reach 2,500 not the 10,000 some had predicted. But a reliable number is days away. We do know at least two americans are among the dead. In tacloban, the city hit hardest, thousands have swarmed the airport, desperate to get out. For now, its women and children first. Those who remain can only try to ward off the smell of death. This was tacloban, a city of 220,000 before the storm. Thats the Convention Center there on the shore. After the typhoon, the Convention Center was just about the only building still standing. Seth doane is in tacloban. Reporter four days after the typhoon flattened this port city, many bodies still lay uncollected on the side of the road wrapped in cloth. Increasingly desperate survivors are scavenging for food. Children begged for water from any passing vehicles. While a Massive International relief effort is under way, there is little evidence of it on the ground. Taclobans airport is open but badly damaged. No power means the planes cant land at night and aid workers are struggling to get supplies in. That didnt stop hundreds of survivors who rushed to the ruined airport looking for food. Others lined up, hoping to be evacuated. By afternoon, the lines stretched three miles long. Bodies pulled from the rubble were lined up neatly. The mortuaries are already overflowing. The situation grew more desperate by the hour. This mother in the nearby town of cebu went over her dead child. Her home is gone. We want to go back home, she said, but we cant. And i have nowhere to bury my child. Many residents covered their faces to mask the smell of the dead while they searched for relatives in some of the hardesthit areas. This filipino man traveled for three days to tacloban, searching for his wife and child. He found them alive. But their home had been swept away. Pelley and seth doane is joining us from the heart of tacloban. Seth, whats it like to be a resident of tacloban today . Reporter well, scott, it is devastating. Theres a lot of wandering the streets, not quite sure what to do. The residents told me they cleaned this street themselves so they could at least get bicycles and motorcycles up and down. But still even days later, im standing really in the heart of the city and there are body bags very close to me that i can see. So this nightmare absolutely continues. Pelley where are People Living . People are living anyplace that they can. You drive through the town and there are little fires burning on the side of the street at night. People are in little leantos, neighbors are together. Homes have just been torn apart. You can see through the homes that remain standing as windows were just cracked, and people are just sleeping out in the open. Last night, we slept on boxes of equipment. Pelley seth doane in tacloban. Well see you on cbs this morning in the morning and right back here tomorrow night. Bill whitaker spoke with josh morgerman, an american storm chaser who raced to the philippines to get as close to the typhoons eye as possible. Hes just back from tacloban. Reporter is this the worst youve ever been through . Absolutely. Like, without a doubt. Pelley when you say intense, describe it for me. Picture the downtown area of a city inside a tornado for an hour. Thats what it was like. It was mayhem. But that was only the first part. As the center passed just south of the city, a. The bay just rose up and swept across the downtown area. That was the storm surge. It came up very suddenly. Pelley we saw the pictures of you saving people on mattresses. The people in the first floor rooms were caught by surprise, so they were in these rooms with the water rising, like these death traps essentially. They smashed the windows and they were screaming for help. When you see someone suffering like that, whos, like, theyre going to die if you dont do something, you dont think about it, you just go. Reporter ive seen the pictures of the aftermath and the devastation, and it looks like a bomb went off. Its awful. Theres a side of you that is so fascinated by the science of these things and you are in awe of it. Then, when you see the human misery part, its a whole other aspect. It breaks your heart. It really does. Reporter he says he helped save as many as ten people, scott, and during the rescue, his friend badly gashed his leg on debris in the water. To save his leg, his friend had to be airlifted out. Pelley Bill Whitaker in our los angeles newsroom. Bill, thank you. 11 million filipinos are affected. Today, the United Nations appealed for 300 million to help them. If youd like to help, theres information on our web site, cbsnews. Com. In an important medical story for americans tonight, heart doctors are putting out controversial new guidelines for preventing Heart Disease. These guidelines put less emphasis on cholesterol numbers and more on other risk factors in determining who should take medication. We asked dr. Jon lapook to fill us in. Reporter a generation of doctors and patients has focused on specific targets of cholesterol levels when using statins. But the new guidelines say when it comes to preventing heart attacks and strokes, there is no magic number. Dr. Neil stone led the panel. We did a careful study of what number we should use. Was it 100 . Was it 90 . Was it 80 . Was it 70 for l. D. L. . You know what we found . We couldnt find a single number that made sense. Adjusting the statin dose to reach a certain cholesterol level, the panel now advises doctors to prescribe er that moderate or high dose depending upon the patients risk factors for cardiovascular disease. The group says patients may benefit from statins if they have a history of Heart Disease or stroke, l. D. L. Or bad cholesterol of 190 or higher, the onset of diabetes between the ages of 40 and 75, or a ten year risk of heart attack or stroke of at least 7. 5 . To measure that risk, the panel created a calculator that considers factors other than just cholesterol including ethnicity. For example, a 50yearold white male with treated high blood pressure, total cholesterol of 220 and good cholesterol of 45 as a tenyear risk of cardiovascular disease of 5 . Statin treatment may not be warranted. But for a man who is African American a group known to be at higher risk the exact same numbers give a risk of almost 9 a level that meets the panels criteria for treatment. Everyone is different. We all have our risks and our individual factors that make treatment either more beneficial or may make treatment more difficult, and to deal with that were urging a patient clinician discussion. Reporter getting rid of target cholesterol levels is such a departure from current practice, its likely to be very a controversial among doctors. But the panel hopes the new guidelines will help remove the false sense of security that can come when a patient on a statin has a very low cholesterol level, but eats poorly and doesnt exercise. Pelley big change. Jon, thanks very much. The troubled rollout of president obamas Health Insurance law is taking a toll on his job approval ratings. In the respected Quinnipiac University poll out today, only 39 of americans say they approve of the job hes doing the lowest ever in that poll. 54 disapprove. Perhaps reflecting his broken you can keep your insurance promise, only 44 said the president is honest and trustworthy. And about that promise came some advice today from former president bill clinton. I personally believe, even if it takes a change in the law, the president should honor the commitment the federal government made to those people and let them keep what theyve got. Pelley Major Garrett at the white house, how is that suggestion playing there tonight . Scott, two senior advisors told us there was no coordination with former president bill clinton on that comment and you can see why. Clintons comments focused even more attention on the most glaring political problem facing obamacare those consumers on the individual market who had their policies canceled but cant afford the new policies that comply with obamacare. The white house is looking for a fix, but it hasnt found one yet. One option is to reinstate the canceled policies, but that would require the cooperation of state Insurance Commissioners across the country, something the white house cannot count on and cannot not necessarily enforce. Another option is to provide more subsidies so people can afford those canceled insurance policies, but, scott, senior advisors have not figured out a way to do that under the law. Pelley more on this to come, major. Thanks very much. Numbers put out by connecticut show that its web site is the only one so far to sign up more folks for private insurance than for medicaid. We asked don daaler to check on what connecticut is doing. Reporter we met 21yearold angel medina signing up for health care in hartford. He was dropped from his mothers Health Insurance two years ago. I have really bad eyes. I like to get them checked often, but since i dont have Health Insurance, you know, doctors really want to, you know, take a look at me. Reporter this month, he found out he may qualify for medicaid that was expanded under obamacare. Connecticuts ultimate goal is to sign up 275,000 people. So far, 9,498 have enrolled. Kevin counihan is chief executive officer of connecticuts health exchange. Are you in any way discouraged with the numbers of people who have been applying for the program here in connecticut . Buying Health Insurance is expensive and its confusing and its complicated, so no, im not disappointed by it. However, we clearly have a strong goal to meet by the end of march and were planning on meeting it, so enrollment has to kick up. Reporter by the end of march, counihan expects to have 100,000 people enrolled. He credits the states Computer System with the smooth enroll. Number one, less is more. Do fewer things well, then do more things inconsistently. Two is test the heck out of the system and make sure before you go live youre confident of whats going to happen and, three, hire the best people you can. Reporter counihan was involved with massachusetts Health Insurance rollout in 2006. Scott, he says that taught him people dont buy insurance like they do a book or a car. They typically look at the options an average of 18 times before making up their minds. Pelley don, thanks very much. Today, the Justice Department dropped its challenge to the merger of American Airlines and u. S. Airways after the airlines agreed to give up some of their takeoff and landing slots at a number of major airports. That will allow lowcost carriers such as jetblue and southwest to expand. If a judge approves the merger, it will create the Largest Airline in the world. Inspectors are finding hazards in a pipeline designed to stretch across america. Experts have made their ruling on whether the new World Trade Center really is americas tallest tower. And whats wiping out the starfish in california . When the cbs evening news continues. Pelley weve found evidence of construction problems on the most controversial pipeline in a generation. The keystone x. L. Is designed to bring crude oil from canada to refineries in texas. Supporters say it will create thousands of jobs and help energy independence, but opponents worry about damage to the environment. Anna werner has been investigating. Youre standing on top of the keystone x. L. Pipeline right now. Reporter crews finished laying the southern half of the Keystone Oil Pipeline through david whitleys texas property last year. So he was surprised in may when a work crew began to unearth the pipe. I asked, is there something wrong . Thats exactly what i said. Is there something wrong . They said, no, we just want to visually inspect a small section of the pipeline. Reporter whitley took video of the section they dug up. It had been laid on top of a massive rock. Workers wrote, dented, cut out. So what was your reaction when you saw this . Well, when i saw it i thought they should have done a better job when they first laid the pipe about getting rid of that rock. Reporter we obtained warning letters written over the past two months to transcanada from the federal agency that regulates pipelines. This september 10 letter warned the company it was not following its own construction specifications because dents on the pipe were found at dig sites with rocky terrain. In a second warning, regulators noted a high weldrejection rate on a section in which 205 welds nearly 50 required repairs. The letter said transcanada failed to use properly qualified welders. Today, the Watchdog GroupPublic Citizen said it has documented 125 sites where the pipe was dug up. Its report notes problems like dents or patches applied to coatings designed to stop corrosion issues that, if not repaired, can lead to leaks. Transcanada maintain it is repairs are normal practice. If they had done the job right in the first place, they would have never been doing digs. Reporter evan vokes worked as an engineer from transcanada from 2007 to 2012. He was fired after he formally complained to his bosses and canadian regulators about what he said was substandard work on other pipelines, also called rightofways. To have a massive amount of patchwork along the rightofway indicate there might be something not quite right with the way the pipeline was put in the ditch in the first place. Reporter transcanada declined our request for an interview, but told us in a statement the repairs are a sign that our promise programs work, that the Company Found and voluntarily reported nh problems cited by regulators and replaced about 700 feet of pipe as a result of construction impacts. Some residents want new leak tests before the pipeline is filled with oil, but trans canada says its not needed, that this pipeline will be the safest ever built. Anna werner, cbs news, texas.
