Sea Level Rise Could Help Marshes Ease Flooding

2016-05-20 13:06:00| Climate Ark Climate Change & Global Warming Newsfeed

Climate Central: Along the mid-Atlantic coast, where waters are rising quickly, marshes are on the march, consuming forestland, farms and yards. "Habitats are changing fast here,' said Matt Whitbeck, a biologist at the Blackwater National Wildlife Refuge in Maryland, where dead trees still jut from young marshes. Newly published modeling shows that a looming acceleration in sea level rise could further accelerate the spread of marshes worldwide. A ghost forest in Bass River, N.J., where marshland is replacing...

Ecological collapse circumscribes traditional women's work in Iraq's Mesopotamian Marshes

PhysOrg: For thousands of years, the marshes at the confluence of the Tigris and Euphrates rivers in modern day Iraq were an oasis of green in a dry landscape, hosting a wealth of wildlife. The culture of the Marsh Arab, or Ma'dan, people who live there is tightly interwoven with the ecosystem of the marshes. The once dense and ubiquitous common reed (Phragmites australis) served as raw material for homes, handicrafts, tools, and animal fodder for thousands of years. Distinctive mudhif communal houses, built...

Heres How Software Could Save Salt Marshes

2016-01-10 06:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Climate Central: It's a mild and sunny summer day on the tidal salt marshes at Barn Island Wildlife Management Area, which sits across Little Narragansett bay from Stonington, Conn. Walking through a wide, dry stretch of marsh, Chris Elphick, a conservation biologist at the University of Connecticut, focuses a spotting scope on a group of little brown birds hidden among the thigh-high grasses. Elphick identifies the rare saltmarsh sparrow by the yellow shading on its face and the crisp dark streaks on its breast....

With CO2 boost, marshes can rise to meet flood risks

2015-12-24 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Climate Central: In the race to keep their verdure heads above rising seas, marshes that protect coastal regions from floods, storms and erosion harbor the botanical equivalents of nitro boosters: rapid growth fueled by climate-changing pollution. The same greenhouse gas that's doing most to warm the planet and uplift its seas can also work as a fertilizer. New research suggests that rising levels of heat-trapping carbon dioxide in the atmosphere could help communities of marsh plants grow quickly enough to keep...

Marshes Likely More Resilient To Sea Level Rise Than Thought, Study Says

2015-12-18 18:01:00| Climate Ark Climate Change & Global Warming Newsfeed

Yale Environment 360: Marshes may be more resilient to climate change and associated rises in sea level than previously thought, according to recent research published in the Proceedings of the National Academy of Sciences. The study shows that as levels of atmospheric carbon dioxide increase, more CO2 gets taken in by marsh plants. This spurs higher rates of photosynthesis and plant growth, causing marsh plants to trap more sediment above ground and generate more organic soil below ground, the researchers explain. The...
