The researchers found that across the 11 western states, of the $50.8 billion of total estimated flood damages during 1978 to 2017, atmospheric rivers accounted for 84% of these damages, exceeding 99% in some areas of the coastal states.
Bounding the southern approach to New York harbor, New Jersey's low, narrow Sandy Hook peninsula is home to an extremely rare forest: a 65-acre patch of eastern holly and red cedar trees, some of which date to the early 1800s. Close to sea level, rooted in nutrient-poor sand and exposed to wind from all directions, such forests once covered much of the East Coast. These few trees have survived the development that has swallowed nearly everything around them, along with countless storms, and—so far—rising sea levels. In 2012, Hurricane Sandy tore through, killing many trees with saltwater inundation and wind. The skeletons of the dead now whiten in the sun. With the slow inland march of rising ocean waters, and the increasing climate-driven potential for future powerful storms like Sandy, how much longer the rest may exist is an open question.

You may not always think about it when you do your laundry or flush the toilet, but whatever you eat, wear or apply on your skin ends up in wastewater and eventually reaches the environment. The use of nanoparticles in consumer products like textiles, foods and personal care products is increasing. What is so special about nanoparticles is their tiny size: One nanometer is one-billionth of a meter. The small size gives nanoparticles unique and novel properties compared to their bigger counterparts and may for example reach locations that bigger particles cannot reach.

The Great Pacific Garbage Patch is often held up as the poster child for ocean pollution. And while the collection of trash collecting in the Pacific Ocean certainly deserves attention, researchers at the University of Delaware are concerned about a smaller source of pollution, much smaller.
They’re barely visible, only 1/8-inch or smaller, so it might not seem like a big deal. But it is. Microplastic particles are floating around in Tampa Bay in alarming numbers. In fact, research scientists from the University of South Florida St. Petersburg and Eckerd College estimate that there may be as many as 4 billion of these indestructible particles at the bottom of the Bay.
A new study has shown that Britain's puffins may struggle to adapt to changes in their North Sea feeding grounds and researchers are calling for better use of marine protection areas (MPAs) to help protect the country's best known seabirds. Britain's coasts support globally important populations of many species of seabird, but they face many challenges as their established habitats change.

Marine sediments play a crucial role in the global carbon cycle due to the oxygen consumption and CO2 respiration of the organisms that live in and on the ocean floor. To help predict the changing contribution of this respiration to the carbon cycle in a warming world, researchers from the Royal Netherlands Institute of Sea Research (NIOZ) and universities in Taiwan have compiled the largest open-access database available of the sediment community oxygen consumption and CO2 respiration. Their findings are published in Nature Scientific Data.
Study may spawn ways to genetically alter and control red seaweeds
Half of the marine life in the world's oceans depends on the enrichment of phytoplankton by dissolved iron, just as plants at the base of the food chain on land need nutrients to help them grow.
Tens of millions of voracious purple sea urchins that have already chomped their way through towering underwater kelp forests in California are spreading north to Oregon, sending the delicate marine ecosystem off the shore into such disarray that other critical species are starving to death.

One proposed method for reducing carbon dioxide (CO2) levels in the atmosphere—and reducing the risk of climate change—is to capture carbon from the air or prevent it from getting there in the first place. However, research from Mark Z. Jacobson at Stanford University, published in Energy and Environmental Science, suggests that carbon capture technologies can cause more harm than good.
The largest synthesis of important marine areas conducted to date reveals that a large portion of Earth's oceans are considered important and are good candidates for protection. A first of its kind, the study was conducted by a multidisciplinary team of researchers including Ellen Pikitch, Ph.D., and Christine Santora of Stony Brook University and Dr. Natasha Gownaris, a Ph.D. graduate of Stony Brook University. The team examined 10 diverse and internationally recognized maps depicting global marine priority areas. The findings, published in Frontiers in Marine Science, may serve as a roadmap for the goal set by the United Nations to create 10 percent of the ocean as marine protected areas (MPAs) by 2020.
