You know what climate change is, right? Well, most of us think we do, until we find ourselves having to explain some aspect of it concisely. Help will come from a new book released today, Global Weirdness: Severe Storms, Heat Waves, Relentless Drought, Rising Seas and the Weather of the Future (Pantheon Books; $22.95).

The 200-page, small format book is a collection of 60 very short chapters—two to three pages each—that explain in straightforward terms a litany of typical questions, statements and misunderstandings about climate change that we hear again and again. The topics are organized into four sections:

• What the science says

• What’s actually happening

• What’s likely to happen in the future

• Can we avoid the risks of climate change?

As such, the book is a handy desk-side reference for anyone who occasionally becomes boggled by these topics, or is in the position of having to teach or explain them to others, whether students, colleagues or the media. Some sample chapters:

• The atmosphere now holds a record amount of CO2—unless you go back half a million years.

• Want an exact number for how warm it will get? Sorry, scientists don’t have one.

• Climate change can be bad for your health.

• Droughts will probably come more often.

• If we made it easier for plants and animals to relocate, we might prevent some species from going extinct.

One nice feature is a string of several short, clear entries on computer models and prediction, which are so crucial to extrapolating the past and present into the future, and which the public so poorly understands. And any reader will like the epilogue, or at least its title: The IPCC is what, exactly?

The book’s author is Climate Central, a nonprofit, nonpartisan science and journalism organization. It was actually written by freelance science writer Emily Elert and Climate Central’s senior science writer, Michael D. Lemonick. The organization’s staff scientists reviewed the text, as did some outside scientists.

One aspects of the book is a bit frustrating. It doesn’t provide a list of the 60 chapters anywhere, which would be very helpful in dipping back inside later when you’re trying to remember where that chapter was about extreme weather. And there’s no index, so you won’t find topics that way either. Maybe the publishers didn't want the book to be categorized as “reference” (not that there’s anything wrong with that!).

Regardless, the book is a breath of fresh air: Just the facts, efficient and easy to understand. It’ll be within arm’s reach of my own desk.

Mark Fischetti was a senior editor at Scientific American for nearly 20 years and covered sustainability issues, including climate, environment, energy, and more. He assigned and edited feature articles and news by journalists and scientists and also wrote in those formats. He was founding managing editor of two spin-off magazines: Scientific American Mind and Scientific American Earth 3.0. His 2001 article “Drowning New Orleans” predicted the widespread disaster that a storm like Hurricane Katrina would impose on the city. Fischetti has written as a freelancer for the New York Times, Sports Illustrated, Smithsonian and many other outlets. He co-authored the book Weaving the Web with Tim Berners-Lee, inventor of the World Wide Web, which tells the real story of how the Web was created. He also co-authored The New Killer Diseases with microbiologist Elinor Levy. Fischetti has a physics degree and has twice served as Attaway Fellow in Civic Culture at Centenary College of Louisiana, which awarded him an honorary doctorate. In 2021 he received the American Geophysical Union’s Robert C. Cowen Award for Sustained Achievement in Science Journalism. He has appeared on NBC’s Meet the Press, CNN, the History Channel, NPR News and many radio stations.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
