Paul Ryan said at a debate Monday. “I don’t know the answer to that question,” Ryan said, in response to a question about whether humans are responsible for the warming of the planet. “I don’t think science does, either.” His remarks were reported by the [Associated Press](http://bigstory.ap.org/article/ea995b2292994d6d8f44fa9782f7aa96/paul-ryan-debate-democratic-house-challenger). Ryan, who is running for reelection in southern Wisconsin against Democrat Rob Zerban, argued that “we’ve had climate change forever” and that proposals to stem climate change are expensive and will not guarantee results. Zerban said humans are to blame for climate change and need to address the issue. The exchange was a heated moment in a wide-ranging debate that included foreign affairs and the economy. Ryan is widely expected to hold his seat in the GOP-leaning district. \[[_AP_](http://bigstory.ap.org/article/ea995b2292994d6d8f44fa9782f7aa96/paul-ryan-debate-democratic-house-challenger)\] ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3505656/paul-ryan-climate-change/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3505656/paul-ryan-climate-change/"},"headline":"Paul Ryan Says Humans May Not Cause Climate Change","datePublished":"2014-10-14T11:34:07.000Z","dateModified":"2026-02-21T10:45:56.848Z","description":"\"We've had climate change forever\"","url":"https://time.com/3505656/paul-ryan-climate-change/","keywords":["2014 Election","Environment","climate change","politics","Paul Ryan"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltb952003952faf633/69876091524fc011dcde9d15/paul-ryan.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Justin Worland","jobTitle":"Senior Correspondent","url":"https://time.com/author/justin-worland/"}],"articleSection":"Politics","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltb952003952faf633/69876091524fc011dcde9d15/paul-ryan.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Paul Ryan","caption":"Paul Ryan","creditText":"Richard Drew—AP","representativeOfPage":true}],"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/politics/","name":"Politics"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/2014-election/","name":"2014 Election"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/3505656/paul-ryan-climate-change/","name":"Paul Ryan Says Humans May Not Cause Climate Change"}}]}] ```
