A Planet of Viruses
Carl Zimmer
A tour of how people have prayed for rain, measured it, sheltered from it, been cheated over it and drawn art from it, and why strange storms of frogs or red rain have real causes.

Most of us treat rain as background noise, a reason to grab an umbrella or cancel a picnic. Yet in Rain: A Natural and Cultural History, environmental journalist Cynthia Barnett shows that a few wet summers in medieval Europe starved some three million people and set off a wave of witch hunts. In Barnett’s telling, rain has never been neutral.
Every civilization has needed it, feared it, prayed for it and tried to predict it, and that double bind explains a surprising amount of human history. Barnett follows the thread from Aristotle’s weather theories to a con man on the American plains, and from rainy Manchester to an English park where frogs fell from the sky.
By the end, an ordinary shower becomes a way to see faith, science, fraud and art. You also gain a handful of stories that make tomorrow’s forecast feel far older and stranger than it looks.

What Barnett’s history adds up to is a long relationship between people and the sky, full of need and suspicion. Our dependence on rain has shaped what we pray for, what we measure, whom we trust and whom we blame. Too little rain sent farmers to a man with a crank. Too much sent Europeans hunting witches. Slowly, patient observation, from bowls in India to telegraph lines in North America, replaced some of that fear with forecasts.
A few habits follow from the book. When a disaster stirs a hunt for someone to blame, ask first what the weather, or the wider system, was doing. When someone’s success matches what any forecast would have told you, give the credit to the forecast. And on the next gray afternoon, try treating the rain the way Woody Allen and Iceland’s many writers seem to, as weather to work in.
The frogs over Birmingham had a cause, and so did the black rain over Britain. Most of what once terrified people about the sky became explainable once someone looked up and wrote it down.
Every drop of water on Earth ultimately comes from rain, yet people have seldom felt comfortable with it. Too little brings drought. Too much rots crops, spreads disease and, in medieval Europe, starved millions. Environmental journalist Cynthia Barnett treats that double bind as a thread running through human history. She follows it through prayer rituals in Islam, Judaism and Native American tradition, and through Aristotle's early theory of a sun-driven weather cycle. Along the way come rain gauges in ancient India and the umbrella, found in almost every early civilization. There is also the dark side: witch hunts after the Great Famine and rainmaking swindlers on the American plains. Then come the lighter and stranger chapters, from rainy cities that seem to breed writers to storms that drop frogs, Saharan dust or factory soot. Readers come away with a set of vivid stories about how one ordinary kind of weather has shaped faith, science, fraud and creativity. They also learn a habit of looking for the real cause behind what the sky seems to be doing.

Listeners find this work captivating and accessible, featuring thoroughly investigated material that examines the impact of rainfall on the development of human civilization. The narrative transitions effortlessly between subjects, and listeners value the blend of historical data and compelling prose. They appreciate the author's perspective on climate shifts, as one listener points out the book's fair and steady handling of the topic.
Barnett’s exploration of the cultural weight of weather is absolutely spellbinding. I never expected to be so captivated by the history of the Macintosh raincoat or the legal battles over windshield wipers. Did you know Mary Anderson actually invented them, only to have Henry Ford take the credit later? The book is packed with these little gems that make you see the world differently. Her writing is supple and wise, blending hard science with the human stories that define our relationship with the sky. I particularly enjoyed the sections on how different cultures interpreted storms. It’s a beautifully researched piece of narrative nonfiction that I’ll be recommending to everyone I know. Truly a five-star read for any history buff.
Show moreThis book flows just like its namesake, washing over the reader with a wealth of fascinating trivia. I had no idea the word "nimbus" from Harry Potter had such deep roots in Latin hydrology. Barnett has a gift for making even the driest scientific concepts feel lyrical and urgent. The way she connects the burning of witches to periods of extreme weather was both chilling and illuminating. Look, some people might find the style a bit too "poetic," but I found it refreshing. It’s rare to find a book that can discuss the devastation of polluted rainwater and the beauty of a Dickinson poem in the same breath. Truly a wonderful achievement that makes the mundane feel magical and important.
Show moreNot gonna lie, I cried a little reading about the struggles of those early settlers on the plains. The story of the farmer Uriah and his devastating loss really puts the "history" of rain into a visceral context. Barnett isn't just reciting dates; she's exploring the human soul and its dependence on the elements. This book is beautifully written and clearly researched with a lot of heart. From the ancient Assyrians to modern-day India, the scope is truly global and impressive. I loved the mix of mythology, technology, and environmentalism. It’s the kind of book that stays with you long after you’ve finished the last page. I’ll definitely be buying copies for my gardening friends this holiday season.
Show moreAs someone who finds the smell of petrichor intoxicating, I couldn't resist picking this up. It’s a fascinating look at how rain has shaped everything from our literature to our cleaning products. I was surprised to learn that Americans crave "rain" scents while Europeans often prefer "sun-fresh" aromas. To be fair, the book does jump around quite a bit between topics. One minute you're reading about ancient Roman cisterns and the next you're learning about climate change models. However, Barnett’s voice is so engaging that I didn't mind the meandering path. It feels like a long, thoughtful conversation with a very smart friend who knows everything about the sky. It is easily one of the more unique history books on my shelf.
Show moreFinally got around to reading this after seeing it on several 'best of' lists for science writing. The chapter on Thomas Jefferson building Monticello on a hill away from water was a real eye-opener about human stubbornness. Barnett does a fantastic job showing how rain—or the lack of it—has driven political decisions for centuries. The transition from historical "rainmaking" scams to modern climate science was handled with remarkable balance and grace. My only minor gripe is that the middle section drags a little when it focuses heavily on fashion history and raincoats. Still, the breadth of the research is impressive. It’s a solid read that makes you appreciate every drop that falls from the clouds, even if it feels jumpy in spots.
Show moreEver wonder why we are so obsessed with something as mundane as falling water? Barnett answers that by digging into the strange rains of frogs and the electrocution of church bell ringers. The "Writers on the Storm" section was a personal favorite, though I wish it had gone even deeper into the music side. It’s an uneven book in parts, specifically when it lingers too long on the chemical soups used by 19th-century rainmakers. However, the overall impact is powerful and memorable. She makes a compelling case for why we need to protect our water systems in an era of rapid climate change. It’s a thoughtful, wide-ranging book that covers a staggering amount of ground without getting bogged down in jargon.
Show moreThe intersection of meteorology and human ambition makes for a surprisingly gripping narrative. I picked this up because of the drought crisis in the West and found it incredibly relevant to our current situation. Barnett’s writing is clear and lively, avoiding the trap of becoming too academic or dense for the casual reader. She moves smoothly from the invention of the umbrella to the complexities of modern weather forecasting. While some chapters are definitely more engaging than others—the raincoat history was a bit dry for me—the book as a whole is a triumph of storytelling. It provides a much-needed perspective on how climate change is altering the very patterns of our lives. This is a must-read for any environmental enthusiast.
Show moreIs it a science book or a collection of anecdotes? I struggled with that question throughout the entire read. While I loved the stories about the "rainmakers" and the charlatans who tried to blast water out of the sky with cannons, I wanted more hard science. The natural history of the water cycle felt a bit thin compared to the chapters on poets and songwriters. Frankly, some of the literary analysis felt a bit like a stream of consciousness that didn't always land for me. It’s not a bad book by any means, but it tries to be too many things at once. If you’re looking for a rigorous meteorological text, this might frustrate you with its lyrical tangents. It's okay, but just inconsistent.
Show moreI really wanted to sink into this book while watching a storm from my porch. Unfortunately, the writing style was just too much for me to handle. Barnett relies on these overwrought metaphors that feel like they’re trying too hard to be profound. At one point, she uses a "Think Indiana Jones" line that made me cringe so hard I almost put the book down right then. The lack of clear organization makes it feel like a random collection of "oh, look at this" facts rather than a cohesive history. I appreciate the research that went into this, but the execution felt scattered and a bit too flowery for my taste. It’s a shame because the subject matter is genuinely interesting, but the author's voice is just too distracting.
Show moreTo be fair, the first chapter on the Earth's formation was quite promising. I was ready for a deep dive into the science of how our planet became a water world. But then the book took a sharp turn into "cultural history" and never really looked back. I found myself bored by the long-winded sections on raincoat manufacturing and the lives of obscure poets. It felt like a potpourri of facts thrown together without a strong enough thread to hold them together. I was expecting something more like a textbook and less like a creative writing project. If you love flowery prose and random anecdotes, you’ll like this. But if you want a focused scientific study, you should probably look elsewhere for your information.
Show moreIt is a natural and cultural history of rain. Barnett argues that people have always both needed and feared it. She follows that tension through rain prayers in several religions, the Great Famine of 1315 to 1322 and the witch hunts it set off, early forecasting from Aristotle onward, the invention of umbrellas and raincoats, rainmaking frauds in America, rain in art and marketing, and strange storms of frogs and colored rain.
Frank Melbourne was among the foremost rainmakers of the 1890s, a swindler who claimed he could summon storms. After demonstrations in Canton, Ohio, in 1891 he charged up to $500 for a good rain across a hundred mile radius. His method, involving a crank and unseen gases, never visibly worked. It often rained on his days because he picked days when rain was already forecast.
Yes, according to Barnett. Reports go back to ancient Greek writers, and in 1954 a woman named Sylvia Mowday was caught in a shower of thousands of frogs in a park north of Birmingham, England. Meteorologists explain that tornadoes and waterspouts can lift water containing fish or amphibians, carry it over land and drop the animals with the rain.
Barnett explains that red rain comes from Sahara dust, which satellite images show being carried thousands of miles across the Atlantic before it falls with the rain. In the nineteenth century, factory emissions were behind the black rain that came down across the British Isles. Rain picked up the pollution from hundreds of British factories and brought it back down to earth.
The book offers a way of seeing as much as a set of facts. When disaster strikes, look for the physical cause before blaming people, as Europeans blamed witches after the Great Famine. Be wary of anyone whose success matches what a forecast already predicted. And consider that rainy days, which Barnett links to writers, musicians and filmmakers, may be good days for creative work.
