report where i live? you can go to cdc.gov, put in where you live and it will tell you how much covid there is around that area. and the second is, what is your risk profile? what is your risk tolerance in the next two to three weeks. if you're going to see somebody who is vulnerable, you might say, for the next two or three weeks, i'm just going to be very careful and wear a mask when i can. >> that's really smart. what about families with kids under 5 who aren't eligible for the vaccine yet? >> really tough. we saw in that piece the mother, how hard it is to keep a mask on any kind of kid. but remember, kids unvaccinated are at risk, and if they do get infected, even though in general they tend to do well, they can get very, very sick and hospitalized. they can also infect other people, their parents and grandparents and other vulnerable people. i think it's worth a try. >> we're just weeks away from

the official start of summer and travel reservations are up 122% since last year. what should you know if you're getting on a plane? >> during flight, there are ventilation systems that are pretty good decreasing the risk of infection. the problem is when you're at the gate. so when you're boarding and getting off the plane, even going to the airport, you may be at increased risk. that might be good tyke to take out the n-95 to decrease your risk. >> dr. lapook, there was news today that moderna plans to update boosters for the fall, that will include protection against the new omicron variant. >> we'll have to see what happens in the fall. for now, people should remember if you're eligible for that second shot, that second booster, to get it. >> dr. jon lapook, thank you so much. well, millions in the east were cleaning up today after severe storms clammed the region. in annapolis, maryland, a man was killed when a tree fell on

this is the cbs "overnight news." crawford in washington. thanks for staying with us. friday is earth day, marking the 52nd anniversary of the start of the modern environmental movement. this year, more than a billion people in 193 countries are expected to take part in events designed to clean up or protect the natural world. l u.n. climate report, there's a lot of work to do. at the top of the list, moving away from planet warming fossil fuels like coal, oil, and natural gas. while cleaner forms of energy,

wind and solar power get cheaper every year, environmentalists are taking a new look at nuclear energy. ben tracy reports. >> so this thing, that's the new reactor? >> that is. that's it. >> reporter: that's the newest nuclear reactor in the united states. there's two of them being built here outside augusta, georgia. when combined with these other reactors built in the 1980s, there will be the largest nuclear power plant in u.s. history. >> we're building the future of energy, and we think nuclear power is a major part of it. >> reporter: chris womack runs the georgia power company, overseeing the final construction of the first nuclear reactors in the country in more than three decades. it's taken years, and cost more than $28 billion. so that is nuclear fuel in there? >> that is nuclear fuel there. >> reporter: he showed us this 47-foot deep sapphire pool containing uranium.

why do we need this? >> our customers need energy 24/7. there needs to be a foundation of our electric grid available all the time. >> reporter: right now, that foundation is fossil fuels, which are rapidly warming the planet, causing devastating and deadly changes to the climate. coal, oil, and natural gas make up 61% of our energy supply in the u.s., renewables such as wind and solar are 20%, and the nation's 56 nuclear plants make up the rest. nuclear power creates no planet warming emissions, and when the wind isn't blowing or the sun isn't shining, the atoms are still splitting. >> it's reliable, safe, affordable and very clean. >> if this is such a great form of power generation, why are these the only two rerscountry? >> we got away from it. >> reporter: because the public turned against it. in the 1970s, concerns over nuclear waste and security

fueled a nuclear power backlash. >> we have a serious condition. you get everybody into safety areas and make sure they stay there. >> reporter: the 1979 film "the china syndrome" stoked fears with a fictional meltdown at a nuclear power plant, 12 days after it hit theaters -- >> radioactive gas is still being discharged. >> reporter: life imitated art in pennsylvania at the three-mile island nuclear facility. no one was killed. but then came 1986. >> u.s. officials believe the disaster at chernobyl began on friday. >> reporter: the meltdown of the reactor in ukraine became the worst nuclear disaster in history. directly killing 31 people, and exposing millions more to the fallout. these accidents made nuclear power itself radioactive. >> nuclear power is dead. it died at three-mile island. >> reporter: dozens of planned nuclear projects were canceled. and the u.s. doubled down on

fossil fuels. but now nuclear power is once again making headlines, as a way to potentially save the world from climate change. >> electricity demand in the united states and really all around the world, is only going up, up, up, up. >> reporter: alex is deputy director of a climate think tak. he says to electrify everything from our vehicles to homes and businesses, we'll need nuclear. >> there's no grid on the planet that relies overwhelmingly on wind and solar for more than even half of electricity generation. everywhere in the world where nuclear gets shut down, it's replaced by largely fossil fuels. >> reporter: after the 2011 meltdown of japan's nuclear power plant, the japanese and germans shut down most of their nuclear power. coal and gas filled much of the void. the u.s. is on track to decommission nine nuclear power units in just eight years. including california's deiablo

canyon plant. >> i don't know why we would take this enormous piece of our clean electricity pie and throw it in the garbage. >> reporter: he argues the impacts of fossil fuels are killing far morehan nur power ever ha and nearly 80 scientists and academics signed a letter, urging california's governor to keep diablo canyon open, warning closing it is irresponsible and potentially catastrophic. >> nuclear power has been getting its shot in the united states for at least five decades. >> reporter: he's with the natural resources defense cou council. he argues nuclear is too costly and take toos long to build to fight climate change. and there's also that other issue. >> our failure to find a nuclear waste solution, which means any community that hosts a nuclear power plant has to be prepared to also host its radioactive

waste for centuries, if not longer. >> reporter: the nuclear industry is touting a next generation of smaller, safer, and less expensive plants. bill gates is funding a company which plans to build its first compact nuclear plant in wyoming. >> i think people can come around. >> reporter: chris womack says he's excited to show that nuclear power has a future, despite being billions over budget. >> nuclear powler be a reliable, stable fuel source for many, many years to come. >> reporter: in what could be a new atomic age. i'm ben tracy in waynesboro, georgia. when the pandemic grounded much of air travel two years ago, the faa noticed an alarming increase this so-called laser attacks. that's when someone on the ground focuses a laser light on an aircraft. last year, incidents were up another 41%. the fbi is reminding people it's a federal offense that can lead to five years if prison and

$250,000 fine. kris van cleave reports. >> we just got hit with a lacer. >> reporter: flying over in florida, sheriffs watch when a helicopter got lit up from a laser aimed at the crew from the ground. >> all you see is green. it's very disorienting. it's almost like a disco ball. once the laser itself hits the cockpit, it bounces everywhere and it's blinding. >> is it is, right from the river. >> reporter: laser strikes on aircraft are soaring, up 41% last year to more than 9700. that's more than one an hour. >> use caution, just had an unauthorized laser illumination event. >> reporter: 47 pilots reported injuries from the strikes last year. the lasers can cause temporary blindness and in some cases lasting eye injuries, and they often occur as pilots are about to land.

>> reporter: in seattle, the fbi is now offering a $10,000 reward after a dramatic increase in laser incidents. pilots reported more than 100 strikes since january. 28 occurred in just three days while airliners were taking off or landing. >> we have to be able to see to land the aircraft. >> reporter: it happened to laura as she was landing at lax. >> i was flying as the captain. the first officer ex-claimed, ahh, and said laser, as the entire cockpit had lit up bright green. >> reporter: the faa thinks part of the reason these strikes are surging is the laser pointers are powerful and cheap. we ordered this one online for about $20. pilots are trained to look away there the laser if they see a strike coming. last year, pilots tested new protective glasses developed by the air force research lab aimed

at filtering out the light to reduce the impact of these strikes. while the number of incidents continues to climb, arrests are rare. >> they're directly at the duplex. >> reporter: but watch one was able to hone in on the lacer, to a 17-year-old with the laser. >> it's not worth it. you're going to have a bad day if you get caught. >> reporter: a barning from police that a beam of light could have you headed to jail in a flash. i'm kris van cleave in sarasota, florida. the cbs "overnight news" will be right back.
