Boston releases 50-year floodproofing plan to meet climate risks

Boston was built on climate resiliency planning. Early residents gradually filled in low-lying Atlantic Ocean tidelands as the city expanded.

MIT experiment reveals pathogen-spreading mechanism of rainfall

Each time a drop of rain hits the ground, small pockets of air at the surface are forced up, emitting a mist of smaller droplets in many directions as air breaks through the raindrop. Exhibiting behavior like an aerosol spray, the phenomenon could explain why freshly fallen rain leaves behind a familiar ‘earthy’ scent. After […]

Chesapeake Bay summer ‘dead zone’ predicted to be slightly smaller in 2016

In Chesapeake Bay this year, the amount of algae that will decay will render a stretch of water approximately equal to the volume of 2.3 million Olympic-sized swimming pools unable to support life. According to the U.S. Geological Survey (USGS), the National Oceanic & Atmospheric Administration (NOAA), and local partners in the Chesapeake Bay watershed, […]
