corps of engineers increased the muddiness or turbidity of the water, public interest in the water supply spiked. >> we had some color issues and stuff like that with the quality of the raw water. >> reporter: one resident, lindsey pearson began reading up on something unrelated to the turbidity of the water, fluoride. >> i am a health care worker. i'm a nurse, and i'm also a mom and i'm educated here in america. i can read articles and peer-reviewed information and

understand when there is a risk. about neurotoxicity and different things related to our cause. and so that's kind of where the ball got rolling. >> reporter: armed with a fluoride data sheet, they pointed at studies that seem to counter the mainstream consensus on water fluoridation. >> fluoride toothpaste. >> reporter: as the debate spread, organizations like the american dental association weighed in. the ada says fluoride, which has been in use for more than 75 years, prevents at least 25% of tooth decay in children and is safe at the level of 0.7 milligrams per liter, which is the amount that lebanon had been using. the debate went all the way up also divided.ouncil, which was - >> every time somebody would send something to the council for us to have as information, it looked like sale brochures. >> reporter: the town voted.

and by less than a four-point difference, the people of lebanon voted to remove their fluoride. >> i'm a firm believer in you giving people their own voice and their own choice in how they focus on their health. personally, i don't think there is a safe level for any kind of a toxic chemical in my water. >> reporter: but that view was not fully shared by everyone. shawn edinger, a former navy engineer voted to keep the fluoride in the water. >> if you trust the government, the consensus is clear. if you run in other circles that don't trust the government, that don't trust the cdc, then obviously they're going to throw all that data and science out the window. >> reporter: we put the question to dentists. some didn't want to be interviewed because of the divisiveness of the issue, but dr. hifam, an ada member dentist and oregon state representative said he can see clearly the difference in his patients' teeth. >> i believe in it. it's a safe thing to use.

>> reporter: another town he works in, hillsboro, isn't fully fluoridated. >> so my hillsboro office, i do see a higher number of patients that do have cavities. when they do have the cavities, the cavities are a lot bigger. it's more severe. >> reporter: and as the debate over water fluoridation spreads to other communities, more towns will have to choose. >> every city is going to have to decide on their own. vote your conscience with it. and i would hope that it goes to the people. >> at the end of the day, i think people who are anti-fluoride aren't bad people. i just think that a lot of times they've been misinformed on information. information. >> reporter: i'm lana zak. when winter season hits emergen-c supports your immune system with so much more than vitamin c. be ready to fight back with emergen-c and for on-the-go immune support try emergen-c crystals. no water needed. patients who have sensitive teeth but also want whiter teeth they have to make a choice one versus the other. sensodyne clinical white provides two shades whiter teeth as well as providing 24/7 sensitivity protection.

the fire storms raging in and around los angeles have now been burning for two weeks. thousands of homes and businesses have been lost, and tens of thousands have been left homeless. climatologists say raging wildfires, more powerful hurricane, and devastating floods have now become the new normal. tracy smith takes a closer look. >> reporter: the monster that roared through l.a. county last week is still alive. but firefighters seem to have it cornered. people have started returning to their homes, or what's left of them. and insurance, if they had it, is a whole other battle. and the focus now is turning

from what happened to why it happened and what in the world is next. this disaster is as bad as just about anybody here can remember, but is it really just the new normal? >> nature is telling us i can't take this anymore. i cannot support you if you keep treating me this way. >> reporter: john valiant is the author of "fire weather: on the front lines of a burning world." and he says climate change is making disasters like the wind-driven l.a. fires fearsome. this is not an anomaly. this is the future? >> we can expect fires of this intensity and worse in the future. the types of fires we've seen over the past ten years are qualitatively different from the previous 100 years. >> reporter: wait, wait, wait. the types of fires are different? >> yeah. >> reporter: how has fire changed? >> in a number of ways. the most potent and frightening way, the most obvious to the

layperson, you know, people like us, is that it moves faster and with greater intensity. you talk to any firefighter with any sense of history, and they are seeing different behavior that is in many cases unfightable. >> reporter: and valiant says the cause is something science has been telling us for decades. the co2 that our combustion engines keep pumping into the atmosphere. >> we don't see it. we don't smell it. we don't notice it. but if you were to take the car engine that brought me here and set it up on the floor here and fired it up, we would go deaf, and then we would die from its emissions. and that's under the hood of every internal combustion engine car. and there are hundreds of millions of them. so the emissions from fire, these trillions of fires that we make every day has created this artificially warm climate. >> reporter: and so, he says, we get more intense fires, stronger

hurricanes, and hotter heatwaves. >> we're going lose everything, and we're not joking. >> reporter: climate scientist peter kalmus has been sitting on and sounding much the same alarm for years. you feel like you're sitting on this information and share it with the world and no one is listening? >> that's exactly how i feel, yes. >> reporter: we met him in 2022 near his home in altadena, just as he was about to move his family to north carolina. was part of that move because you were worried about wildfires? >> yeah. so for a few years, i wanted to move to some place a little bit less fiery. but i want to make it clear, i don't think there is any place safe from climate change. >> reporter: kalmus learned that firsthand last year when north carolina was trashed by hurricane helene, and the california fires were a disaster for him as well.

his old house in altadena and his friends' homes automatic all burned to the ground. >> i'm hopeful that if there is a silver lining to this tragedy, it's that, you know, the public will wake up and get angry and say we need to do something about this. enough is enough. >> reporter: scientists like peter kalmus have been warning the world about impending climate disaster for years now. but on january 6th, as the fire closed in on altadena, perhaps the most effective warning came from this guy. edgar mcgreggor has been picking up trash in altadena every day for more than five years. he is also into meteorology, and runs a facebook page about weather. days before the fires even started, he warned his facebook followers about dangerous conditions. and on january 6th, he posted a video telling them to drop everything and get out of town. >> do not wait for official

evacuation orders. if you think you should leave, et out. get out! >> reporter: you literally said get out? >> i said get out. i stood in the middle of the street at my home, filmed myself with the mountains on fire behind me, and told people this is serious. get your social security cards. get the deed to your home, get out. this is the big one. i'm not joking around. this is not going to blow over. >> reporter: jen seifert, an altadena mother of two, didn't need to hear that twice. how much of a difference do you think edgar made? >> i think -- i think -- well, he definitely saved my family's life. we all listen to him. this kid knows what he's talking about. >> reporter: her own house somehow survived. her neighbors weren't so lucky. >> my best friends, they've lost everything. >> reporter: but they're alive. >> they're live. probably because of edgar. i would imagine. everybody in the beautiful altadena group is alive because of edgar right now.

>> reporter: jen seifert had never met edgar mcgreggor in person, so we asked if she wanted to shake his hand. >> i'm sorry. i'm so happy. >> reporter: jen, edgar. edgar, jen. >> hi. >> hi. i've seen all your views. >> i'm sorry. i'm sorry. this is horrible. >> i'm so appreciative of you. >> thank you. >> and you saved my family, and you saved so many people. so thank you. >> reporter: the fires, experts say, are a warning on a much bigger scale, that the earth will continue to get dryer and more volatile, unless we do something about climate change. but, of course, warnings only work when people listen. have we just pushed nature too far? >> the upside to all of this is nature is inviting us sternly to

reengage. it's only going to get hotter. and so nature is saying wake up. we are in this together. it behooves all of us to focus on the real causes and to understand that this really can happen to us, to us, to you and to me. not just to people we know or people on tv. >> that was tracy smith in los angeles. stay with us.

president donald trump's promise to shake up u.s. foreign policy has sent political shockwaves across the globe. for some, it's a reason to hope. but others have a different view. holly williams has the story from ukraine. >> reporter: president trump's return to power is front-page news around the world and just as controversial globally as it is in the united states. >> i'm very optimistic about this. i think it's the change that america needs. >> donald trump is an absolute waste of space, in my opinion. he is no good for any country. >> reporter: in ukraine, many people are worried.

they've survived nearly three years of war after russia's invasion of their country, but now some here fear that trump will cut off the supply of american weapons. during the campaign, donald trump repeatedly claimed that he could end the war between ukraine and russia in 24 hours. some ukrainians fear that could mean forcing their country to surrender territory to russia without security guarantees to stop vladimir putin launching another invasion. and in china, there are fears that trump's policies could exacerbate trade tensions with the united states. "china's economic environment is already quite bad," says this man in beijing. "if the trade war continues, it won't be good for ordinary people." but in israel, even before he took office, president trump was credited with helping to push through a ceasefire deal, which had already seen the release of three female hostages held in

gaza for over 15 months. holly williams, cbs news, kyiv, ukraine. and that's today's "cbs news roundup." for some of you, the news continues. for others, tune in later for "cbs mornings," and follow us online any time at cbsnews.com. reporting from the cbs broadcast center in new york city, i'm shanelle kaul. ♪

news found had criminal pasts ahead of january 6th. and the former new york city police officer, who was serving about ten years for assaulting police outside the capitol. the pardons are a gut punch for police victims and some congressional staff like sharon nichols, who barricaded inside an office as the rioters pillaged. it seems like it would be troubling to know everybody just got pardoned. >> yeah. i mean more than troubling. it's made me angry. i've been fighting some disillusionment. i think we're g in a pretty dar period. >> reporter: far right protesters enrique tarrio and stewart rhodes were released with more than ten years on their sentences. >> president trump did the right thing letting these guys out. they did not get a fair trial. >> reporter: j.d. vance and pam bondi have all said in recent days those who were violent shouldn't be included in

secretary of defense, he's truly a danger. >> reporter: danielle hegseth, who was married to hegseth's brother also alleged samantha had a plan to get away from hegseth by texting a safe word to her if she needed help. during his confirmation hearing, hegseth denied any allegations of violence toward his former wives. >> did you ever engage in any acts of physical violence against any of your wives? >> senator, absolutely not. >> reporter: to be confirmed, hegseth can only afford to lose three republican votes. some, including maine's susan collins, are still deliberating. >> i had told you earlier that i was undecided. >> reporter: in a statement to cbs news, an attorney for pete hegseth says his ex-wife samantha never alleged any abuse in court documents or to the fbi, and he called danielle hegseth's claims belated and false. nikole killion, cbs news, capitol hill. multiple new wildfires had crews busy in san diego on
