The past is key to the future: Historical observations strengthen modern science

 

Written records of natural phenomena come from personal journals and diaries, newspaper accounts, ship logs and government documents, among other sources. Such accounts often offer descriptive details and context that cannot be matched by other methods, and they can prove extremely useful in broadening records both temporally and geographically. Given that they predate the sort of widespread instrumental readings that scientists have come to depend on, sometimes there is simply — and literally — no substitute for historical data. Despite their advantages, historical records are used infrequently in modern physical sciences. That may be changing, however.

Lofted by hurricanes, bacteria live the high life

With cold temperatures, low humidity and high levels of ultraviolet (UV) radiation, conditions 10 kilometers above Earth’s surface may seem inhospitable. But next time you’re flying, consider this: The air outside your airplane window might be filled with an array of microscopic life that affects everything from weather and climate to the distribution of pathogens around the planet.

Risky business: Modeling catastrophes

Natural hazards — earthquakes, tropical cyclones and thunderstorms, for example — occur with considerable frequency around the world. Fortunately, most events are either not intense enough or too remote to cause damage. But the probability that a given natural hazard could become a natural disaster is higher today than at any previous point in history.

Benchmarks: October 13, 1947: A disaster with Project Cirrus

Two days after clipping Cuba and Florida, a hurricane was drifting out into the Atlantic. All predictions had it remaining at sea without further landfall, making it the perfect test subject for the newly minted Project Cirrus, a U.S. government- backed project bent on discovering a way to disable deadly hurricanes. The researchers planned to seed the hurricane’s clouds with dry ice, hoping that the ice would interact with the clouds and disrupt the cyclone’s internal structure, thus weakening it. So on Oct. 13, 1947, a plane flew over the storm and dumped 80 kilograms of dry ice into the storm’s swirling clouds.

Is it time to invest in entrepreneurial geoengineering?

Government research and development has its limits: Time, money and bureaucracy can all hamper the timely progress of research. As a result, many federal agencies are looking to private companies to help drive new innovation and keep costs down — but it’s never that simple. Two current hot-button topics — returning humans to space and geo­engin­eer­ing — highlight a range of issues related to how private and public investment in science can coexist. Last month, we looked at NASA’s push toward privatization.

Biophysical economics: The Mississippi Delta as a lens for global issues

With a global economic slowdown and growing environmental concerns, it is worthwhile to take a look at the future and think about how we can better manage development relative to society, natural ecosystems, climate and energy. These global issues can be viewed through the lens of the Mississippi Delta.

Court rules against Army Corps in New Orleans flooding case

A district court judge ruled Wednesday that the U.S. Army Corps of Engineers is liable for much of the flooding in New Orleans following Hurricane Katrina in 2005. The ruling puts the Corps and the U.S. government on the hook for millions if not billions of dollars in damages and punitive penalties, and could open the floodgates for more such lawsuits nationwide, experts say.

Hurricane Ike sent Galveston's beaches out to sea

On Sept. 12, 2008, Galveston was a picture-perfect seaside Texas town, with an extensive stretch of beach lined with beautiful homes. But a day later, when Hurricane Ike roared across Galveston Island, the storm surge flooded the barrier island, washing away houses, roads and tons of beach sand. Now researchers have figured out where all that sand went.

Benchmarks: September 21, 1938: The great New England Hurricane strikes

After a disappointing golf outing (the wind made it impossible to drive a golf ball anywhere but straight up), golf pro Raymond Dennehy and his friends returned to the clubhouse of the seaside Kittansett Golf Club in Marion, Mass. Dennehy noticed something wrong: The incoming tide was much higher than normal. In fact, the ocean rose so high that it cut off the club’s grounds from the rest of the state. Then a car floated by./  As water filled the clubhouse, Dennehy took his German shepherd and ran to his car. He drove to the highest point on the golf course and waited. Sitting in the parked car with water around his ankles, Dennehy watched the two-story yacht club collapse under the weight of the rising water. Cottages crumpled. Panicked golf caddies climbed an oak tree to escape the rising sea.
