New York, New Orleans, Charlottetown and Everywhere Else
The disaster in New Orleans was almost uniquely awful in modern American history. But even if Katrina isn’t likely to happen everywhere, something can happen almost anywhere—including, we now know, New York. And further to the north and east.

Spontaneous Clumping of Tropical Clouds
If you take a look at nearly any satellite image of clouds in the tropics, you’ll notice that the clouds tend to be organized into clusters. One specific type of cloud organization called “self-aggregation.” Self-aggregation is the tendency of tropical clouds to spontaneously clump together, solely due to interactions between the clouds and the surrounding…

Head for the Hills
While we spent much of our time examining corals and swamps, studying sea level and storms, we became fascinated by a simple question: How did the hills of Exuma form?

The Extreme Pacific Climate Now
The climate over the tropical Pacific is in an extreme state at the moment. That explains some of the extreme anomalies affecting the United States right now. It also gives us a window through which we can glimpse how even more dramatic and long-term climates of the distant past might have worked.

Sediment Cores from Exuma’s Shores
Because we know little about hurricane behavior during periods when Earth was warmer or colder than at present, it’s challenging to construct models to predict future trends in hurricane activity as Earth’s climate changes. To remedy this problem, researchers have been working to reconstruct records of hurricane strikes in the past.

Hurricane Histories and Carbon Mysteries
The Bahamas might be a vacation destination for most people. But for us, they represent an excellent site to study several different questions about past, present and future climates.

Behind the Expected Quiet 2015 Hurricane Season
On May 27, 2015, NOAA officially announced a likely below-normal Atlantic Hurricane season is coming up. The range for the possible numbers of major hurricanes is 0-2. What are the reasons behind it? How precise are these numbers?

Recent research suggests that Sandy may have been much more likely than previously believed.
