And we do say, good morning, america, from here in times square and iceland this morning, so much excitement for this unprecedented live event. I guarantee you are going to learn something new this morning and as you can see, amy is there, were going to learn something and its also very cold, right, amy . Thats right. Robin, by far this is the coolest live shot i have ever been a part of literally and figuratively. We are standing in the middle of the melting glacier and scattered all throughout this glacier are massive vertical sinkholes that are treacherous going hundreds and thousands of feet into the earth where ice is melting faster and faster as water levels in the atlantic rise even more. Now, behind me i have an Intrepid Group of ice climbers who are helping researchers gather data about that melting ice and how it affects all of us, all of our shorelines. We have an amazing never before just a minute. Cannot wait to bring it to you guys. Unbelievable. Looks like a green screen. It looks so unbelievable . Another planet. Really incredible. Well have a lot more from iceland. We begin with breaking news overnight. North korea claims it has detonated a Hydrogen Bomb. If true, this would be a major breakthrough for the rogue state. Its already ratcheting up tension around the world, the u. N. Security council calling an emergency meeting and Martha Raddatz starts us off. Good morning, martha. Reporter good morning, george. The u. S. Immediately launched socalled Nuclear Sniffer planes to try to determine whether or not north koreas claims are true, but it could be weeks if not longer before we know for certain. The announcement came from north korean state media claiming that the tremors which caused a 5. 1 magnitude earthquake in the northeast part of the country were the result of north koreas First Successful test of a those are far more sophisticated and about a thousand times more powerful than atomic bombs like those dropped on hiroshima and nagasaki in world war ii. There has been no confirmation and lots of skepticism, but it raises immediate concern about north Koreas Nuclear program. Earning condemnation from countries around the world, including north koreas friend, china. This would be the countrys fourth time testing a Nuclear Weapon since 2006 but it would be the first time testing a thermoNuclear Weapon. There is as we noted a lot of skepticism as to whether this was a Hydrogen Bomb because the initial size and s sle of the tremor is similar to tests in the past but, george, no one wants to rule it out just yet. Not at all and the North Koreans saying a miniature Hydrogen Bomb. You talked about that there. What can the world do about this . Heavily sanctioned its hard to see what else they can do and the bottom line is that if this is a Hydrogen Bomb or any kind of nuclear test, those sanctions and the condemnation clearly have not worked, george. Okay, Martha Raddatz, thanks very much. Startling to wake up to that news this morning. Now to those powerful storms slamming the west coast. A series of them moving in, one each day triggering torrential downpours and flooding in california. And abcs Indra Petersons is in glendora, california, this morning. Good morning, indra. Reporter Drought Conditions in california you would think rain would be welcome but for residents here el nino means too much rain way too fast. Overnight a west coast washout. Here comes el nino. Reporter el ninofueled rains drenching california where roads became rivers proving fun for some but dangerous for others. Floodwaters invading backyards. Reporter parking garages, and this restaurant. Hotel, muddy waters full of debris trapping many commuters in their cars. Take a look at the street. Youre seeing rails lining both sides, something you see on a freeway but this hillside above me is bare and 15 minutes quarter of inch rain is expected to take mud barreling down the street. Today theyre more concerned. They added steelenforced wooden barriers hoping this will keep the heavier rain expected today. Robin. Indra, well talk about that. Thank you so much. Rob, those storms as we just heard not letting up. Really, robin. We havent seen a series of storms like this in a week for over five years in california. This is serious business. Flash flood watches that remain up through at least tonight for several more pulses. From San Francisco to los angeles and another pulse coming through tonight and tomorrow morning. Locally up to 5 inches of rainfall and another one coming in behind that. Snow, of course, at the Higher Elevations but with another storm coming this weekend and really in january this is when el nino storms start to hit california and we are just beginning this onslaught. George, back over to you. Thanks. We move on to the battle over gun control right now and those tears from president obama during his passionate pitch for new action yesterday. And from every family who never imagined that their loved one would be taken from our lives by a bullet from a gun Pierre Thomas in washington. Pierre, the president s anger and emotions so palpable yesterday. But the opponents of his new executive action are putting up a fierce fight too. Reporter good morning, the president clear impacted by the daily carnage in places like chicago and all those Mass Shootings especially newtown, tears flowing as he announced a series of actions from increasing the number of firearm sellers at gun shows who must register with the federal government and do background checks to better tracking of guns lost in shipping and asking congress for a half billion dollars to expand Mental Health treatment but reaction from the nra and the gop was fast and as the nra calling the president condescending. George, i was struck by all those families from the tragedies some who told me they are in this fight for the very long haul. They say they want to lead a movement. Gun control a big issue on tuesday. Also last night donald trump continue to take aim at bill respond directly to the gop frontrunners attacks and Abcs Cecilia Vega is here with the latest on that. Good morning, cecilia. Reporter rob and george, good morning to you. A new attack line from donald trump with those Iowa Caucuses right around the corner. It is all on the line right now. It has become Donald Trumps goto attack line in 2016 and this morning, he is back at it. The gop frontrunner not mincing any words when it comes to bill clintons past. Dont forget he lost his law license. He wasnt allowed he was impeached. Theres a lot of things going on there and she calls me sexist. Reporter overnight in new hampshire, trumps eye still on that target. The one person that hillary does not want to run against is donald trump, believe me and bill doesnt want it either. Reporter Hillary Clinton sticking to her new years resolution to not respond. We should not reward people who use inflammatory rhetoric who use the kind of derogatory comments. Is not a sign of leadership. Reporter the race for the white house heated on all sides. And standing directly in clintons path, vermont senator bernie sanders. Yesterday in iowa she did not hold back. Im a progressive who likes to get things done and i will get into that white house, i dont need a tour. I know right where the oval office is. I know right how to get things done. Reporter yeah, clinton had another jab for sanders also asking those iowa voters to not just take into consideration things like experience and qualifications when choosing a electability and brings in the big gun today bill clinton hitting the trail in iowa for his first Solo Campaign trip there, george. Okay, cecilia and bernie here now. Candidate. From Hillary Clinton in a second. First breaking news overnight from north korea. Another nuclear test, perhaps a Hydrogen Bomb, if you were in the oval office what would you do about it . Flean on china. China is north koreas closest ally. Theyll have to push north Korea International agreements. How do we lean on china . China, we have a relationship. China is equally concerned about what north korea is doing. North korea is a paranoid isolated nation. They are when you have a Hydrogen Bomb, if thats true, you are a threat to china, as well. How about this argument from Hillary Clinton clearly believes that she can make the pitch shes far more electable than you are. I would suggest secretary clinton look at the last quinnipiac poll which has me leading trump by a significantly higher margin than she does and thats true of other poll, as well, look, two things, number one i believe that our campaign is generating the kind of grassroots excitement that will result in a high voter turnout. Democrats need a high voter turnout to win. I think we can do that. Second of all, for a variety of reasons i think we can do better against trump or other republicans than can secretary clinton. Whats the number one reason . Is that the issues that we are talking about, the disappearing middle class, massive levels of income and wealth inequality and the fact that wall streets greed has had a huge impact on the lives of millions of people, people want leadership now to stand up to the big money interests, protect working people, thats what ive done my whole life. Secretary clinton says her plans to take on wall street are tougher than yours. Actually they are not. Were talking about breaking up the large Financial Institutions, so that the middle class of this country will not again have to bail them out. Were talking about the reality that when you have a handful of banks, half a dozen banks that have assets equivalent to 60 of the gdp of america. Thats dangerous to our economy and political life. You have to break them up and reestablish glassstegall legislation. That is not secretary clintons position. A lot of experts said thats not fundamentally at the core of what the problem is but i i disagree with that. That is exactly what the core is. So many were created by the banks that werent under glasssteagall. Financial institutions. Youve also said that youre upset that the leaders of those Financial Institutions, some did not go to jail. Can you point to any one that there was evidence they committed a crime. Since 2009, large Financial Institutions have paid over 200 billion in fines. Now, if youre paying 200 billion in fines for illegal activity and reaching settlements with the government, you tell me if there was not culpability. Can you name an individual . Give you one example, wachovia, which was later bought by wells fargo, was convicted of laundering mexican drug money. What do you think . You think somebody might be guilty . 200 billion in fines. Nobody prosecuted. I think what you have is a situation where banks are not only too big to fail, bankers are too big to jail. 3 1 2 weeks away from iowa. We got a great shot. Theres a lot of enthusiasm. Were bringing out big crowds. Senator sanders, thanks for joining us this morning. We appreciate the candidates continuing to come to our studios. We turn to ethan couch, new details this morning about the socalled affluenza teens wild night while on the run in mexico with his mother as she gets ready to head back to texas to face charges after her day in court. Abcs matt gutman has the latest. Reporter theres a first words weve heard from tonya couch yes, i do. Reporter the mother of the socalled affluenza teen since she and her son ethan took off for mexico. Are you the tonya couch that is wanted by the state of texas . Yes. Reporter the suburban mom with the red ringlets mostly obscured behind the bars accepting extradition to texas. Her lawyer telling us shes committed no crime. How would you describe her . Her two main concerns remain about her son, ethan and how he is doing in mexico and her dog virgil. He met his attorney for the first time tuesday. We had a chance to confer but im not at liberty to disclose what we talked about. Reporter ethan is fighting deportation to texas where authorities hope to charge him with violating probation and tonya with hindering his apprehension. The boys whose legal team cried affluenza during his drunk driving trial in 2013 may have caught another case of it while on the run in mexico, staff at this Puerto Vallarta strip joint telling abc news he spent at least one night here. Employees telling us he was not alone. His mother went with him. Employees say she left and he stayed drinking heavily going into a vip room with two female employees. Staffers tell us he got staggeringly drunk, racked up a 1,000 bill mostly on lap dances and when he couldnt pay the bill they hauled him back to his resort and his mother, who also couldnt pay, ended up leaving his rolex as collateral. Robin. All righty there, matt. Thanks so much. Our thanks to you. Powerball fever. The big drawing is tonight.

Holmes is going to break it all down for us at Fordham University football stadium. Good morning to you. Hey, strahan, robin, i am here at coffey field with a simple dime to illustrate your chances of winning the lottery tonight. Are you ready . Now, im going to blindfold you both, bring you down here and tell you to walk out on this field, walk directly to that dime and pick it up. Those are your odds of winning toongt. Ive put together an analysis that will help you improve your odds. First of all, dont pick numbers based on your kids birthdays or in fact, dont pick the numbers at all. Let the computer do it. 70 to 80 of Powerball JackpotWinning Tickets have been computer picks but if you insist on picking the numbers yourself, try these, 8, 54, 14, 39, 13. Those are the most frequently drawn numbers in the past four years. Another way to improve your odds, move to pennsylvania. 16 jackpot winners have come from that state the past 13 years. After that indiana and missouri both 11 winners each. Even if you dont win the jackpot there are going to be tonight. But the thing is most of those millions of winners are only going to win 4 bucks for matching one number. Thats something. Thats it . Or that dime because i will yeah. Excited about that dime you threw out there. Hey, t. J. , thank you very much. All right, michael, well turn to a disturbing scene with this High School Ref and a yeah, not the best show of sportsmanship and was all caught on video during a game in langhorn, pennsylvania. Police were called to this high school after a coach appeared to head butt a ref. There is the coach. Hes walking towards the ref. Jerry devine, he leans in and the ref goes down and the announcer tried to stay it was the coachs body language after he went down to say i didnt mean to head butt him but he just the video says it all. The video says it all. The referee was not hurt in any of this. Thats good. But i think if youre going to be a coach you got to be a great example. Come on. You have to display sportsmanship if you expect your players to display it. This got out of hand. As an athlete you know emotions get wild but you have to hold it in check. Youre the coach. Youre the leader, the teacher. That video doesnt lie. He leaned in on that. Michael, thank you very much. Its a little bit warmer here on the east coast. A little bit. But still scenes like this at least yesterday in bryant park, the fountain there. Moderating. Still a chilly morning. No doubt about that.

Reporter but lawyers for the father and daughter say it was selfdefense. He was the one that called 911. Tom tried to revive jason. Hes trained in Law Enforcement and there would be no reason for him to act any way inconsistent with that except to protect himself and his daughter. Reporter Molly Martens met jason corbett, a widower in ireland in 2008 when she served as the family au pair taking in 2011, the couple married and moved to america. Immediately after her husbands death, martens made several attempts to gain custody of his children. But a judge handing them over to corbetts family.

The tsa also stating that the childs bag contained a cell phone that alarmed requiring additional resolution procedures. The tsa has modified their screening policies in the last few years to reduce the likelihood of a patdown for children so kids under 12 can leave on their shoes and a light jacket and like you saw on that video they wont be separated from their parents but clearly thats not enough for payne who also pointed out that his daughters patdown lasted nearly two minutes. The tsa is in a tough position. You know, theyre there to protect us and Something Like this happens, the father was able to watch. You have young daughters. I mean, how would you feel if you saw that.

And you have always cautioned about prescription sleep aids. So what is your prescription to getting more sleep. Listen, we could talk about first thing is we have to remember make sleep a priority. If you dont commit to that in terms of your health trust me, things will suffer and fall like the second thing i say is we have to drop the guilt. No one is going to die if the dishwasher is not loaded or so whatever doesnt get done by the time we need to shut it down, it doesnt get done. We dont need any more guilt and try not to selfmedicate. Whether thats with alcohol, over the counter prescription aids, these things can work in the short term but in the long term really not good and if you have questions talk to your doctor or pharmacist about it and lastly meditation. You got it, girl. I just started that last year. Makes the difference. I do it too. I will tell you 20 minutes a day, i hear from my patients that i write a prescription, meditate. It costs nothing. It can make a huge difference. Well talk more about meditation next week. Thank you. Youre going to be busy on twitter again. Also go to our facebook page, as well with any questions that you have.

Look at that glacier right there. You see those little figures right there. Amy is with those climbers. They are about to go down inside that sinkhole. Amy, whats going on . Yeah, thats right. You know what, george and everybody, we are here at ground zero. These are the front lines of Climate Change. Scientists use glaciers just like this one to monitor Global Warming and our elite ice climbers behind me are ready to go into this massive ice tunnel. In fact, well have drones following them every step of the way so lets get up in the air, drones and follow our ice climbers as they head into the abyss, live from the land of fire and ice. Oh, my gosh. We brought you fire. Were just getting inside that crater. Camera over an active volcano. Now were bringing you ice. The immense forbidding ice sheets of iceland home to a hidden world of Crystal Clear ice caves, glistening glaciers and dangerous crevasses constantly changing. Gearing up for this treacherous journey has been a multiday expedition. Perfectly safe . Yeah. He hesitated. Reporter first trying my hand on the ice, then by car and foot, our Team Trekking nearly a mile through water, rocks and lascapaze,ing, daerousa fngt. Losingn average of 11 biion tons of ice per year, this satellite picture taken in 1986 and this one 28 years later iceland is melting at a rate of a foot per day and that water has to go somewhere. When youre talking about changing sea level youre talking about impacting the reporter including miamis coastline, those waters already climbing an inch a year. And take a look at this. If sea levels keep rising, in two centuries scientists warn that city could completely under water, charleston, too, even new york. So this morning were plugging far below the surface of the ice in a never before attempted live event going deep into this glacier vatnajokull, the front lines of Climate Change taking you inside a glacial sinkhole a massive drainpipe for melting ice that can be thousands of feet deep for a firsthand look glacier expert from vander lt university. Hell be walkis ngrowhat icclrs see as they go to that massive ice tunnel so lets send them on the wiray, l right. Hey,uys, go for it. Go ahead and start ice climbg. Tell me, danwh resrcrs hope to find when they get to e bottom and see what is at the boom oholenkthisne td oferticacagi ua ross s into the glacier so can tell how ieha fwi be d hoanmpss t is,ts ngh w and u t dot ss you g herend to it a ses th sta to go dwe what iat that were looking atn the ice . Tthe debrhais cg inth isofrheolca tht too. How significant ie melting that were seeing here in t ms of ntributions tohe t rising sea levels we see across the atlant and other oceans. Yeah, i mean whats melting here gets inheceto a t coast of the u. S. Right now. How fast is this glacier, the yeah, so right now its actually retreating at about 300 feet every year. So its going almost a foot a day that its retreating back but its also thinning and lowering at about 100 feet a year right now. All right. Its retreating and thinning. As we watch our climbers descend into this tunnel, this ice cave, how and why do these form in the first place . Yeah, these are melt water ponds that form on top of the glacier from warm days and actually cloudy days sometimes too and those ponds suddenly drain through cracks in the glacier and expose these amazing vertical tunnels. All right. We also want to say as were watching these incredible climbers go down into this hole, how do they measure you mention numberings, how fast these glaciers are melting. How do they measure that . Yeah, here in iceland actually there is a long tradition of icelandic people monitoring and marking where the doing that. Now we can do some with Satellite Technology and were doing it with drones now. Right and how do Scientists Use these drones for their research . What do these drones show them that we couldnt have otherwise seen. Right, drones are really sorting Cutting Edge Technology for scientists. They give us access to places we otherwise couldnt get to and able to monitor things closely on a daily basis that way and whats amazing is they give us realtime and 3d information about how earths fast is changing. And do you know what the bottom looks like as were watching this incredible video of our climbers . I mean this is really remarkable watching them scale this massive ice wall. It takes tremendous skill, tremendous expert but its all to get to the bottom, what do you expect theyll see when they wekingt meing ic li drained out through this cavern system, got to the base of the glacier and probably helped him flow faster and thin and end up in the sea. Incredible and, george, you have a question. I wanted to ask dan, first of all, such a stunning sight but have we ever seen melting like this before in other periods of history or is this all brand new . Have we ever seen, george wants to know periods of melting like this in history or is this the first of its kind that we know of. Yeah, so throughout geologic time and certainly for the last 2 million years weve gone through warm periods but what were seeing is a real rapid increase in the rate of thinning and melting that were seeing and thats related to human induced Climate Change. Now, robin, you have a question. I do. Could you ask dan how does this compare, what were seeing here, other places in the world, are have glaciers. Dan, robin wants to know how what were seeing here, this melting, how does it compare to other glaciers around the world, say, in greenland or in other areas youve studied antarctica, as well. Go big or go home time for gmas ultimate tailgating challenge. We are all penn state oh, my goodness. It is a competition and, lara, its your turn. A nod toour alma mater, penn state.

This is how they look when theyre done andhe tse are a classic. Theyre so good on game day with the beverage of your choice. I like to use chuck and spray thpan with a little pam or any Vegetable Oil and brown the meat. It is browning you add your seasonings, they include and i want to make sure i get all of them. Ground black pepper, oregano, cumin, garlic powder, chili powder that goes into your ground beef. Once that is done i prefer the large chip, the restaurant style because you can get more nacho goodness on your chip. And then also this is something that karen from gma taught me a couple of years ago. We do two layers. I use a pan and i put it in the oven, but two layers. You do a layer of the chips and you do your meat then you add all of your goodies. Ooh. And this is how it will come out and i will show you what i put in it. The be, youve got monterey jack, youve got cheddar, you have salsa. I use a store bought. I do make my own guacamole. Ill tell you about that in a sec. I love black beans. Im not competitive at all, amy. Also, i prefer instead of plain jalapenos, pickled. Why . Not quite as biting so you dont burn your tongue off so once you are done, things are heated. I like to put it in the oven. So far im getting good reviews then for the guacale add a little lime juice, that ll keep iteall its very sple. A little bit of garlic, a little bit of salt.
