But what makes Daniel special is that he doesn’t just do the fundamental science, he somehow finds the time to explain it to the public. When disasters happen, he appears regularly on cable news programs; is quoted in seemingly every related news article; and engages directly with people through social media, his blog, and his virtual “office hours,” all in an effort to inform the public and policy­makers. Turning lemons into lemonade, Daniel has even found a way to parlay his own personal struggle with a sometimes debilitating rare autoinflammatory condition into an opportunity to discuss, in his affable manner, issues such as uncertainty and risk and how they apply to both us as individuals and the planet we inhabit. _Mann is a professor of earth and environmental science at the University of Pennsylvania_ ```json [{"@context":"https://schema.org","@type":"Article","@id":"https://time.com/collections/time100-next-2025/7318846/daniel-swain/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/collections/time100-next-2025/7318846/daniel-swain/"},"headline":"Daniel Swain","datePublished":"2025-09-30T10:42:59.000Z","dateModified":"2026-03-03T00:54:37.612Z","description":"","url":"https://time.com/collections/time100-next-2025/7318846/daniel-swain/","keywords":["TIME100 Next","sponsorshipblock"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt7f1706bd9ec41b88/6998c9f1d32e937a06cd759f/t100-next-2025-daniel-swain.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"TIME Staff","jobTitle":null,"url":"https://time.com/author/time-staff/"}],"creator":"TIME Staff","articleSection":"World","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt7f1706bd9ec41b88/6998c9f1d32e937a06cd759f/t100-next-2025-daniel-swain.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/world/","name":"World"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/time100-next/","name":"TIME100 Next"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/collections/time100-next-2025/7318846/daniel-swain/","name":"Daniel Swain"}}]},{"@context":"https://schema.org","@type":"VideoObject","name":"See Everyone on the 2025 TIME100 Next List","description":"","thumbnailUrl":"https://cdn.jwplayer.com/v2/media/ICSs7gXk/poster.jpg?width=720","uploadDate":"2025-09-30T10:00:00.000Z","contentUrl":"https://cdn.jwplayer.com/manifests/ICSs7gXk.m3u8","embedUrl":"https://time.com/collections/time100-next-2025/7318846/daniel-swain/","duration":"PT1M59S","potentialAction":{"@type":"SeekToAction","target":"https://time.com/collections/time100-next-2025/7318846/daniel-swain/?jw_start={seek_to_second_number}","startOffset-input":"required name=seek_to_second_number"}}] ```
