Author Eric Jay Dolin appears with his new book “A Furious Sky: The Five-Hundred-Year History of America’s Hurricanes.”

Fifteen years ago, Hurricane Katrina smacked into New Orleans and produced one of America’s worst natural disasters. The destructive capabilities of these storms have spurred scientists and governments to improve technology and search for ways to limit the impact on humans. In his fascinating and thoughtful new book, “A Furious Sky: The Five-Hundred-Year History of America’s Hurricanes” Eric Jay Dolin talks about history-making storms.

Q: What fascinates you about hurricanes?

They’re the greatest storms on Earth, the ultimate in reality TV, and all-encompassing events that are among the most gripping stories you can tell. In the book, I use the hurricanes as a narrative backbone to tell a broader story about American history and the evolution of meteorology, communications, television, satellite technology, and computer modeling. It all comes back to this seminal event, which is the hurricane itself.

Q: What gives hurricanes so much power?

Heat is the No. 1 source of the hurricane’s energy. The process begins when the upper layer of the ocean in the tropics, going down about 150 feet, reaches a trigger point of 80 degrees F. As vapor travels through the air, it condenses into rain as it gets cooler. It’s that heat, the latent heat of condensation, that really provides power: The warmer the waters are, the more energy potential there is. There have to be other conditions too. The main one is that there has to be relatively little wind shear. If the wind blows in different directions at different heights, it tends to rip apart the hurricane or shove it over on its side.

Q: Will we ever be able to perfectly predict the path of a hurricane? 

We have computerized weather models that can do millions of equations, and the cone of uncertainty [around a hurricane’s predicted path] gets narrower and narrower. But hurricanes are incredibly complex meteorological events. It really comes down to MIT meteorologist Edward Lorenz’s chaos theory, known as the butterfly effect. It’s not that a butterfly flapping its wings in one part of the world is going to [directly] cause a hurricane in another part of the world. His point is that small changes in conditions can result in big changes in the future.

Q: Can the U.S. improve its response to hurricanes? 

There’s reason for hope. But in order for that hope to be turned into reality, there has to be volition and determination on the part of individuals, communities, regions, and the entire country. We need to take effective steps to protect people and clean up after hurricanes. All those things require forethought, planning, and most importantly, money and political will.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to CSMonitor.com.
