Atmosphere with Emily Gracey

What happens when a wildfire creates its own weather? Can artificial intelligence detect a fire before it spreads? And could autonomous drones someday help firefighters protect entire communities?Meteorologist and wildfire chaser Jaclyn Whittal has spent years covering extreme weather, from hurricanes and tornadoes to devastating wildfires. But after moving to British Columbia, the wildfire threat became personal. She's experienced evacuation alerts, watched the sky turn red with smoke, and swept burning embers off her own back porch.In this episode of Atmosphere, Jaclyn joins meteorologist Emily Gracey to explore the science behind wildfires, their connection to our changing climate, and some remarkable new technologies being developed to fight them.We talk about fire-generated thunderstorms, fire tornadoes, "zombie fires" that survive the winter, AI-powered detection systems, firefighting drones, and new ways to protect homes and communities.And perhaps most importantly, why preparing for the next wildfire season needs to start long before the first flames appear.Sponsored by Weather100.

Why do some communities suffer far greater consequences from the same weather disaster? And what can we do to change that?When Hurricane Katrina struck in 2005, meteorologist Dr. Jamese Sims urged her parents to evacuate. Her father refused, insisting he needed to "protect the house." It took years for Jamese to fully understand what he meant, and that experience helped inspire her new book, Protect the House: Weather Doesn't Discriminate, But Impact Does.In this episode of Atmosphere, Jamese joins Emily to explore why weather disasters disproportionately affect underserved communities. From financial barriers and generational wealth to cultural beliefs and the lasting impacts of disasters, she explains why preparing for extreme weather isn't as simple as telling people to evacuate or have an emergency kit.They also discuss where traditional weather communication falls short and share practical ways families, meteorologists, and community leaders can work together to make everyone safer.Because a good forecast can only save lives if people have the information, resources, and support to act on it.Atmosphere is proudly supported by founding sponsor Weather100.

Who decided we should change our clocks twice a year? And why are we still doing it?From the days when every town kept its own time to America's failed experiment with permanent daylight saving time in 1974, meteorologist Emily Gracey takes a quick trip through the surprisingly messy history of timekeeping.Plus, why Arizona refuses to play along, how China manages with just one time zone, and what all of this has to do with saving energy.For more on the science of daylight saving time and how it affects our sleep and health, listen to the full Atmosphere episode featuring Stanford sleep researcher Dr. Jamie Zeitzer.Sources & Further ReadingCongressional Research Service — Daylight Saving Time: https://www.everycrsreport.com/reports/RS22284.htmlU.S. Department of Transportation — The Daylight Saving Time Study: A Report to Congress (1975): https://rosap.ntl.bts.gov/view/dot/92250Smithsonian National Museum of American History — On Time: Synchronizing Time: https://americanhistory.si.edu/ontime/synchronizing/zones.htmlArizona State University — Why Arizona Has Opted Out of Daylight Saving Time: https://news.asu.edu/20180305-discoveries-why-arizona-has-opted-out-daylight-saving-time?page=3Timeanddate — Daylight Saving Time in Arizona: https://www.timeanddate.com/time/us/arizona-no-dst.htmlTimeanddate — China Only Has One Time Zone: https://www.timeanddate.com/time/china/one-time-zone.html

Twice a year, Americans change their clocks. Twice a year, we argue about whether we should stop. But what does the science actually say?Stanford sleep researcher Dr. Jamie Zeitzer joins Atmosphere to unpack the surprisingly complicated science behind daylight saving time. Is permanent standard time really healthier? And are we overlooking a much bigger problem while arguing about the clocks?From the Sunshine Protection Act to our alarming lack of natural daylight, Jamie explores how sunlight affects our circadian rhythms, sleep, and overall health. He also shares surprisingly simple ways to get a better night's sleep, explains why some of us are night owls while others are early birds, and challenges some conventional thinking about changing the clocks.Maybe the problem isn't what time we're setting our clocks. It's what we're doing with the daylight we've got.Atmosphere is supported by founding sponsor Weather100.Learn more at https://weather100.com/ and use code EMILY20 for 20% off your purchase.

What if simply looking up at the clouds could help NASA?Satellites can observe Earth in extraordinary detail, but there's something they can't do: stand on the ground and look up with the human eye. And that human perspective turns out to be incredibly valuable to scientists.In this episode of Atmosphere, meteorologist Emily Gracey talks with Dr. Andy Sayer, an atmospheric scientist working with NASA's PACE satellite, and Jessica Taylor from NASA's GLOBE Clouds program about the surprising limitations of satellite technology and how everyday people can help fill in the gaps.Through NASA's free GLOBE Observer app, anyone with a smartphone can collect cloud observations that contribute to real scientific research. No scientific background required!But there's another benefit to all this cloud watching. Taking a few minutes to look up can reconnect us with nature, help us appreciate the world around us, and maybe even bring a little peace to our busy lives.Become a cloud observer:NASA GLOBE Observer app: https://observer.globe.gov/about/get-the-appPACE Clouds Challenge: https://www.globe.gov/do-globe/measurement-campaigns/field-measurement-campaigns/pace-clouds-challengeAtmosphere is supported by founding sponsor Weather100.
