Increased Temperatures Spell Trouble for Corals
ST. PETERSBURG, Fla.— Late-summer water temperatures near the Florida Keys were warmer by nearly 2 degrees Fahrenheit in the last several decades compared to a century earlier, according to a new study by the U.S. Geological Survey. (more…)
COLLEGE PARK, Md. – Cold-sensitive mangrove forests have expanded dramatically along Florida’s Atlantic Coast as the frequency of killing frosts has declined, according to a new study based on 28 years of satellite data from the University of Maryland and the Smithsonian Environmental Research Center in Edgewater, Md.
Between 1984 and 2011, the Florida Atlantic coast from the Miami area northward gained more than 3,000 acres (1,240 hectares) of mangroves. All the increase occurred north of Palm Beach County. Between Cape Canaveral National Seashore and Saint Augustine, mangroves doubled in area. Meanwhile between the study’s first five years and its last five years, nearby Daytona Beach recorded 1.4 fewer days per year when temperatures fell below 28.4 degrees Fahrenheit (-4 degrees Celsius). The number of killing frosts in southern Florida was unchanged. (more…)
Finds surprising growth patterns in the Florida Keys
ST. PETERSBURG, Fla. — A new more sensitive weight-based approach for monitoring coral growth in the wild has been developed by U.S. Geological Survey researchers leading to more definitive answers about the status of coral reefs.
Corals and other marine organisms build their skeletons and shells through calcification, the biological process of secreting calcium carbonate obtained from ocean water. This new approach to measuring corals can provide finer-scale resolution than traditional linear measurements of coral growth. (more…)
Decreasing emissions of black carbon, methane and other pollutants makes a difference
With coastal areas bracing for rising sea levels, new research indicates that cutting emissions of certain pollutants can greatly slow sea level rise this century.
Scientists found that reductions in four pollutants that cycle comparatively quickly through the atmosphere could temporarily forestall the rate of sea level rise by roughly 25 to 50 percent.
The researchers focused on emissions of four heat-trapping pollutants: methane, tropospheric ozone, hydrofluorocarbons and black carbon. (more…)
Don’t believe in Santa Claus? Magic, you say? In fact, science and technology explain how Santa is able to deliver toys to good girls and boys around the world in one night, according to a North Carolina State University researcher.
NC State’s Dr. Larry Silverberg, professor of mechanical and aerospace engineering, can explain the science and engineering principles that allow Santa, also known as Kris Kringle or Saint Nicholas, to pull off the magical feat year after year. (more…)

EAST LANSING, Mich. — When it comes to economic development in American cities, the trusted old theory “If you build it, they will come” may not work, a Michigan State University sociologist argues in a new study.
Conventional wisdom holds that job growth attracts people to urban areas. (more…)
A new study from North Carolina State University finds that anti-immigrant practices – such as anti-immigrant legislation or protests – are likely to backfire, and spur increased political action from immigrant communities. The study examined political activity in 52 metropolitan areas across the United States.
“U.S. Census data indicate that 60 percent of the foreign-born in the U.S. are not citizens,” says Dr. Kim Ebert, an assistant professor of sociology and co-author of a paper describing the research. “Non-citizens can’t vote, so we wanted to determine how they are participating in political life.” (more…)
