Permafrost Thawing Could Accelerate Global Warming
2014-04-08 15:41:51

Kathleen Haughney, Florida State University A team of researchers lead by Florida State University have found new evidence that permafrost thawing is releasing large quantities of greenhouse gases into the atmosphere via plants, which could accelerate warming trends. The research is featured in the newest edition of the Proceedings of the National Academy of Sciences. “We’ve known for a while now that permafrost is thawing,” said Suzanne Hodgkins, the lead author on the paper...

West Antarctica is losing weight in the form of billions of tons of ice per year, making its mantle rock softer. This rock is being nudged westward by the harder mantle beneath East...

Economical Solutions For Maintaining Critical Delta Environments
2013-12-10 08:47:46

Woods Hole Oceanographic Institution Millions of people across the world live or depend on deltas for their livelihoods. Formed at the lowest part of a river where its water flow slows and spreads into the sea, deltas are sediment-rich, biodiverse areas, a valuable source of seafood, fertile ground for agriculture, and host to ports important for transportation. At least half of the deltas around the world are so-called “wave dominated deltas” – open to the sea and under the...
