If you check the latest research of the Global Monitoring Laboratory on CO₂, you will find a record that shows a rise from 340 ppm in 1980 to almost 425.83 ppm in 2025, marking the sustained growth since the NOAA measurements began. This also means that from 2021 to 2025, there are now 85 more molecules of CO₂ trapping heat. That shift is now what scientists call critical, according to many new books on climate change published in 2025.
Writers like Bill McKibben and Elizabeth Kolbert continue to shape how we understand this emergency. Thanks to them, we also see new conversations from Ayana Elizabeth Johnson and Genevieve Guenther, both frequent TED speakers. And of course, Al Gore, who still stands as a reference point. Based on that, we’ve gathered the titles below. We also took into account popular publishing sources and the book summary app to provide the core ideas and copies to stay up to date on the climate stories shaping 2025.
