How to Prepare for (And Survive) a Flood

Startling images of the massive floods inundating Kentucky illustrate the scale of damage that can result from immense rainfall, which has caused rivers throughout the Bluegrass state to massively overflow their banks. On Monday, Governor Andy Beshear declared a state of emergency, announcing in a statement that the …Read more...

Underwater Robot Stealthily Swims With a Propulsion System You Can't See

Sound travels faster and farther underwater because it’s denser than air, and that can make it harder for researchers trying to study marine life who get an early heads up to go into hiding. But a new underwater robot could move stealthily through the waves using a propulsion system that doesn’t rely on a propeller or…Read more...

Humans Have Completely Transformed How Water Is Stored on Earth

Human fingerprints are all over the world’s freshwater. A new study published Wednesday in the journal Nature shows that while human-controlled freshwater sources make up a minimal portion of the world’s ponds, lakes, and rivers, they are responsible more than half of all changes to the Earth’s water system.Read more...

How to Keep Your Basement from Flooding When Snow and Ice Start to Melt

Over the past few weeks, many parts of the country have experienced serious winter weather—including areas that don’t normally see that kind of snow and ice. And eventually that snow and ice melts, creating more water than usual, and some homes can’t handle it. Fortunately, there are a few things you can do to prevent…Read more...

Groundwater Depletion Threatens 20% Of India's Winter Farmland

In India, agriculture employs more than 50% of the country. It’s also in crisis due to climate change and groundwater loss. A new study shows how these two factors are putting the country’s farmers at risk.Read more...

A Huge Red Flag Just Popped Up in a Little-Studied Region of Antarctica

Glaciers in Antarctica are turning the concept of “glacial pace” on its head. A new study of a little-observed area on the continent finds that rising heat is making ice streams flow faster, which has worrisome consequences for sea level rise.Read more...

A Major Ocean Current May Be Hurtling Towards Collapse

The ocean may have less time than we thought before massive, irreversible shifts take place. A new study finds that a crucial ocean system may reach its “tipping point” sooner than predicted if the rate of climate change continues at a breakneck pace.Read more...

Make Your Loved One Swoon With NOAA's Adorable Satellite-Themed Valentines

Ever since I was a little girl, one of my favorite things about Valentine’s Day has been the cards.

You Should Use Ice in Your Brine

Whether you’re planning to roast a big ‘ol turkey or a head of cauliflower, a good brine ensures the final product is tender, moist, and flavorful throughout. Simple brines are little more than sugar, salt, and water, but peppercorns, citrus zest, bay leaves, and all sorts of plant parts can be used to make things…Read more...

The Arctic Ocean Was Once Filled With Fresh Water, New Research Suggests

Stunning new evidence suggests the Arctic Ocean was covered by a thick layer of ice and filled with fresh water on at least two occasions during the past 150,000 years. The observation could finally explain strange and dramatic climate anomalies associated with these glacial periods.Read more...

The Atlantic Ocean Is Getting Wider Thanks to Upwelling Magma

In March 2016, a research team dropped 39 seismometers to the bottom of the Atlantic Ocean off the western tip of Africa, to listen for the rumblings of earthquakes near and far. A year later, they’ve found a hidden story of how the continents are growing farther apart—not pulled from either side by subduction zones,…Read more...

‘Extinct’ Volcano Mouse Is Actually Doing Fantastic

When a colossal plume of ash and lava exploded from Mount Pinatubo in the Philippines in 1991, few people probably had their minds on the animal life in the area, much less one species of rodent. The Pinatubo mouse was feared extinct after the eruption, but 30 years later, it turns out that the scrappy critters are…Read more...

This Giant Ice Cube Represents How Much Ice We're Losing Every Year

We talk about ice a lot here on Earther—or more specifically, the growing absence of it. A new study puts what’s happening to the planet in striking perspective. While I can tell you the results show 1.2 trillion tons of ice disappeared every year since 1994, it’s a lot easier to grasp as a visual.Read more...

Characteristics of severe thunderstorm and lightning activity in the Beijing metropolitan region

Severe thunderstorm is a kind of high-impact weather process producing lightning, heavy precipitation, hails, and wind gust, and still very difficult to be forecasted accurately up to now. A recent study published in Science China: Earth Sciences reported the characteristics of thunderstorm and lightning activity in the Beijing metropolitan region, and the result indicated that lightning data could be assimilated into the numerical weather model to improve the forecast of severe thunderstorm and...

Portland geologist Lalo Guerrero shares the dirt on local trails

40-year-old molten lava from Plains of Abraham trail in Washington. Lalo Guerrero.(Photos: Lalo Guerrero/Trailside Geology) One of the best things about bikes is how they lead to so much discovery. In urban areas their relatively slow pace and open-air design helps connect people to their surroundings in a much more intimate way than cars do. And when riding on trails, bikes can take you to awe-inspiring places where rocks, water, trees and dirt create mother nature’s murals. “A bi...

POWDER PEOPLE: Interview with Avalanche Forecaster Nikki Champion

The prodigious amount of snow that coats Utah’s mountain ranges brings many a grin to skiers and snowboarders across the state. However, the depth of such snow, the terrain, and localized weather conditions may harbor the ingredients to unleash deadly avalanches. Luckily, the  works tirelessly to help everyone stay on top with their detailed avalanche forecasts, awareness campaigns, and readily available avalanche education courses.We sat down with UAC’s newest forecaster, Nikki Champion, to see...
