New Satellite Boosts Research On Global Rainfall and Climate

Read the full story at Yale Environment 360.

Although it may seem simple, measuring rainfall worldwide has proven to be a difficult job for scientists. But a recently launched satellite is set to change that, providing data that could help in understanding whether global rainfall really is increasing as the planet warms.

Scientists Focus on Polar Waters As Threat of Acidification Grows

Read the full story at Yale Environment 360.

A sophisticated and challenging experiment in Antarctica is the latest effort to study ocean acidification in the polar regions, where frigid waters are expected to feel most acutely the ecological impacts of acidic conditions not seen in millions of years.

Column: Farmers engaged in Iowa Water Quality Initiative

Read the full story from the Daily Globe.

Many Iowa farm fields are turning green earlier than normal this spring as a rapidly growing number of farmers are using cover crops to help better protect the soil and water they depend on to make their living. Farmers are always looking for new and better ways to raise crops and livestock, and cover crops is a promising tool starting to catch on as way to prevent erosion, improve soil health and limit nutrient loss.

Streamer

Streamer is a new way to visualize and understand water flow across America. With Streamer you can explore our Nation’s major streams by tracing upstream to their source or downstream to where they empty. In addition to making maps, Streamer creates reports about your stream traces and the places they pass through. Streamer is fueled by fundamental map data for the United States at one million-scale from the National Atlas.

Water stress magnifies impacts of U.S. droughts

Read the full story in GreenBiz.

Dried-out fields and dwindling reservoirs are becoming all too common across the United States as companies, farms and municipalities stagger along under years-long droughts. Worsening dry conditions affect two-thirds of Texas. California’s historic drought shows no signs of improvement. Exceptional to moderate drought conditions extend in pockets from Oklahoma north through Minnesota. And in Colorado, The Denver Post wrote, “comparisons to the Dust Bowl are no longer hyperbole — they’re accurate.”

“Years of Living Dangerously,” a new Showtime series about climate change, turned its lens on how drought devastated the small town of Plainview, Texas in its first episode, which aired Sunday night. Drought drove a Cargill beef-processing plant — Plainview’s largest employer — to close in 2013. More than 2,000 jobs disappeared in a town of 22,000.

In Plainview — and every other drought-stricken place across the United States — a precipitous drop in rainfall is only part of a much broader story. Underlying water stress is one important piece of that complicated puzzle. When drought strikes where baseline water stress is high, it exacerbates regions’ water woes.

California looking to recycled water to ease drought concerns

Read the full story in the Sacramento Bee.

At two treatment plants in El Dorado Hills, millions of gallons of brown wastewater pour in every week, and millions of gallons of clean water pour out through purple pipes that irrigate the lawns of 4,000 homes.

Proponents call it water recycling. Critics call it “toilet-to-tap.” But as the drought has taken hold in California, opposition to the idea has been drying up, and recycled water is winning acceptance. It’s expected to be a significant source of landscaping and drinking water for many Californians in years to come.

Scale Model WWII Craft Takes Flight With Fuel From the Sea Concept

Read the full story from the U.S. Naval Research Laboratory.

Navy researchers at the U.S. Naval Research Laboratory (NRL), Materials Science and Technology Division, demonstrate proof-of-concept of novel NRL technologies developed for the recovery of carbon dioxide (CO2) and hydrogen (H2) from seawater and conversion to a liquid hydrocarbon fuel.

Fueled by a liquid hydrocarbon—a component of NRL’s novel gas-to-liquid (GTL) process that uses CO2 and H2 as feedstock—the research team demonstrated sustained flight of a radio-controlled (RC) P-51 replica of the legendary Red Tail Squadron, powered by an off-the-shelf (OTS) and unmodified two-stroke internal combustion engine.

NRL researchers (l to r) Dr. Jeffrey Baldwin, Dr. Dennis Hardy, Dr. Heather Willauer, and Dr. David Drab (crouched), successfully demonstrate a novel liquid hydrocarbon fuel to power the aircraft's unmodified two-stroke internal combustion engine.

Flying a radio-controlled replica of the historic WWII P-51 Mustang red-tail aircraft—of the legendary Tuskegee Airmen—NRL researchers (l to r) Dr. Jeffrey Baldwin, Dr. Dennis Hardy, Dr. Heather Willauer, and Dr. David Drab (crouched), successfully demonstrate a novel liquid hydrocarbon fuel to power the aircraft’s unmodified two-stroke internal combustion engine. The test provides proof-of-concept for an NRL developed process to extract carbon dioxide (CO2) and produce hydrogen gas (H2) from seawater, subsequently catalytically converting the CO2 and H2 into fuel by a gas-to-liquids process.
