Scammed this Holiday Season. Good evening and thank you for joining us on this saturday. Im cecilia vega. As we come on the air tonight, people around the world are celebrating a turning point on our planet. It took two decades, but now, a historic agreement on Climate Change signed by nearly every nation in the world. The bang of a gavel cementing the deal, a limit on Greenhouse Gas emissions that could reduce the effects of Climate Change. President obama offering his praise a short time ago, saying the agreement offers the best chance to save the one planet we have. But there are protesters weighing in, too. Criticizing that deal for not going far enough. What is certain tonight, the affect of this agreement will be felt for generations. Abcs Alex Marquardt starts us off tonight. Reporter a standing ovation and tears tonight, as almost every country in the world agreed to the landmark deal aimed at preventing catastrophic Climate Change. Tonight, the white house called it the most ambitious Climate Change agreement in history. This agreement represents the best chance weve had to save the one planet that weve got. Reporter 195 countries signing onto the agreement. The culmination of two decades of negotiations that had failed, until now. In the end, two weeks of intense talks outside paris, including several allnighters for the delegates, led to the deal that goes into effect in 2020. Whose goal is limiting the warming of the earth to less than 3. 6 degrees fahrenheit. Each country came up with a plan to reduce their Greenhouse Gas emissions and will be required to publicly report them. Weve reached an agreement here that is the strongest most ambitious global Climate Change agreement ever negotiated. Reporter but much of the agreement is voluntary and not legally binding. Developing countries, like china, which has seen horrendous smog in recent weeks, wont be required to report as much about their emissions, and the deal doesnt have a way to punish countries that dont live up to the agreement. Climate scientists agree that Global Warming wont end because of this deal and while some are saying it falls short, its being celebrated around the world as a momentous breakthrough. Cecilia . Alex, thank you. And we want to turn now to our other top story, to california. Police tonight questioning a person of interest in a firebombings at a mosque there. Investigators say it was a hobble ha possible hate crime. Abcs aditi roy reporting in from the scene tonight. Reporter inside the blownout door of this Southern California mosque, the charred lobby, barely recognizable, after a fire authorities believe was arson and are now arresting 23yearold carl dial for a possible hate crime. Commercial structure fire with battalion 6a on scene. Reporter the blaze erupting just past noon yesterday, after eye witnesses say a firebomb was hurled at the mosques front door. Theres a huge plume of smoke. Mushroom cloud. Reporter several inside managing to escape as the lobby caught fire. Worshippers later moved prayers to the sidewalk. When you look at this, what goes through your mind . Sadness, actually. Its a family place. Its a social place for us. We just have to work on rebuilding it again. Reporter the Islamic Society of the Coachella Valley mosque is just 75 miles from San Bernardino. The fire, one of several incidents that officials are investigating, as possible backlashes to those terrorist shootings. In all, there have been three times as many cases of vandalism and harassment at mosques this year than last. Says the council on American Islamic relations. In philadelphia, Surveillance Video of a pigs head thrown at a mosque. Threatening voicemails left at a mosque in st. Louis. Come my way and ill [ bleep ] you all. Cut your [ bleep ] head off. Reporter are you worried about other attacks happening . We are concerned about other attacks. The answer is yes. Reporter the acting imam here tells me it is unclear how long it will take them to rebuild. Meantime, they are doubling security and reassuring families here that they are safe. Cecilia . And that damage just devastating. Aditi, thank you. Not too far from where aditi is reporting tonight, the desperate hunt for clues in that terror attack in San Bernardino. Fbi divers recovering objects from the bottom of this lake. No word yet on whether they are linked to the husband and wife killers. And a childhood friend of one of the shooters being questioned again today, police saying he bought their most deadly weapons. All of this as more victims are are laid to rest. Abcs Kayna Whitworth reporting in from San Bernardino tonight. Reporter for the third day, searchers combing through this muddy lake in San Bernardino. The fbi telling abc news, divers have pulled items from the water and are now analyzing them for any connection to syed farook and tashfeen malik. Investigators are still looking for the couples missing hard drive. Tonight, farooks childhood friend, enrique marquez, who bought the two rifles used in the attack, now in his sixth day of questioning by the fbi. He is probably sitting somewhere, what i would describe as fbi hotel. So, he continues to talk and describe whatever he knows about syed and the female that was, you know, part of the attack. Reporter marquez hasnt been charged with a crime, and says he knew nothing about the plans for the San Bernardino attack. But what he has told investigators is that farook had planned an attack in 2012, but got cold feet. Nick rodriguez, who knew marquez from a local bar, said he remembered one chat back in 2013, but shrugged it off as drunk banter. He would just talk about how there are so many sleeper cells and when its going to happen, its going to be big. Reporter rodriguez believes marquez is partly responsible, no matter what he knew about the attack ten days ago. He turned his back on america. Like i said, innocent people are dead. Families broken up this holiday. People are missing. Theres presents underneath the tree that are never going to be opened. Reporter today, those families saying goodbye to three victims, including shannon johnson, who saved the life of his coworker, denise perazza, by shielding her from the bullets. His last words to her . I got you. Hes always about taking care of those who cant take care of themselves. Reporter shannons brother described him as fearless today.

Abcs mary bruce reporting in from the white house. Reporter tonight, the bromance between donald trump and ted cruz is on the rocks. Its not a contest between the two of us, just so we understand. Reporter as cruz gains ground, trump for the first time is taking aim at the texas senator, targeting his faith. I do like ted cruz, but not a lot of evangelicals come out of cuba. Reporter in iowa, trump jabbed cruz for opposing popular ethanol subsidies. If ted cruise is against ethanol, how does he win in iowa . Because thats very antiiowa. Reporter this iowa farmer tells us its trump or bust. Anybody else gets in, its the same old garbage. Nothing gets done. Reporter you think hes the only one . I think hes the one that can get it done, yeah. Reporter but trump also has kind words for his chief rival, saying cruz would have a role to play in a his administration. We would certainly have things in mind for ted, to be honest with you. Reporter in South Carolina today, trump came under fire for his call to ban muslims entering the u. S. But he stands by his controversial proposal. We dont want people coming in and knocking down World Trade Centers and having what happened last week. Reporter now, trump is already responding, blasting that new poll that shows cruz with a tenpoint lead. Trump tweeting tonight, dont trust the Des Moines Register poll. He says it is biased towards trump. Cecilia . Mary bruce at the white house tonight. Thank you. And there will be a big democratic debate, too, right here on abc.

Keep the weather. Thank you for joining us. Nice to see you. And we do turn now to hundreds of parents in californias bay area. They are worried about what their newborn babies might have been exposed to at the hospital. What one nurse may have spread to those hundreds of patients. Abcs Ron Claiborne has the latest. Reporter the news was stunning. 350 newborn babies at this san jose, california, hospital, possibly exposed to a nurse who tested positive for tuberculosis. Those infants will now undergo daily treatment with antibiotics for the next six to nine months as a precaution. We have to assume they might be infected and start them on medications, until we can show for sure that theyre not infected. Reporter in addition to the babies, 368 mothers and 338 hospital employees, who came into contact with the nurse between september and november, will be monitored, but not treated unless they test positive for tb. According to officials, the nurses annual tb checkup in september was negative. But in november, she saw her doctor for an unspecified complaint. And that doctor ordered a chest xray, which led to the diagnosis. The nurse has been placed on paid leave of absence. Tb is transmitted through the air, by a person coughing or sneezing. She was not coughing up tuberculosis during the period of time that she was working. Reporter but the hospital decided to act just the same, and local Health Officials and the hospital say they have identified everyone who may have been exposed to the disease. And theyre working through the weekend to contact them and begin scheduling appointments. And i should add, cecilia, doctors we spoke to said the antibiotics the newborns are getting are very safe and side effects very rare. Tough for that hospital, but really scary for those brand new parents. Reporter really is. Something else scary, if you havent finished your Christmas Shopping tonight, i havent.
