Arctic change has widespread impacts
As the Arctic warms faster than the rest of the globe, permafrost, land ice and sea ice are disappearing at unprecedented rates. And these changes not only affect the infrastructure, economies and cultures of the Arctic, they have significant impacts elsewhere as well.

Beach building is keeping the Atlantic Coast from going under
The artificial build-up of beaches is buffering the U.S. Atlantic coastline against the effects of sea level rise, but that benefit may not last as sand gets harder to come by in the coming decades.

Barrier island sand dunes recover at different rates after hurricanes
Sand dunes on coastal barrier islands buffer the U.S. Atlantic and Gulf coasts from oncoming hurricanes. Every year, millions of public and private dollars fund the restoration of these barrier islands, but managers often focus on the recovery of smaller sand dunes and aim at making them bigger, for better storm protection. But new research presented at the 2018 AGU Fall Meeting last month finds sand dunes on these barrier islands don’t all recover at the same rate. Small dunes go back to becoming small dunes; large dunes recover to be large dunes; and they don’t typically grow larger than they were before the storm struck.

Scientists counter threat of flooding on coral reef coasts
Scientists have developed a computer simulation tool to predict short-term flood hazards on coral-reef-lined coasts and to assess longer-term impacts from climate change. The assessments will give input to estimate societal or economic risk and damage from such flooding.

Study finds widespread land losses from Gulf oil spill
A new study shows dramatic, widespread shoreline loss in Louisiana marshlands most heavily coated with oil during the 2010 BP Deepwater Horizon oil spill in the Gulf of Mexico. Following the spill, the length of shoreline that receded more than 13 feet (4 meters) a year quadrupled compared to the year before the spill. The land losses occurred mainly in areas where oil had washed ashore during the spill.
