What lies beneath melting glaciers and thawing permafrost?
Around the planet, ice is rapidly disappearing. From mountain tops, the poles, the seas, and the tundra. As the ice melts, it's exposing new surfaces, new opportunities, and new threats—including valuable mineral deposits, archaeological relics, no.....»»
Heavy water: How melting ice sheets and pumped groundwater can lower local sea levels—and boost them elsewhere
Imagine you're standing near the edge of the Antarctic Ice Sheet, gazing out over the ocean, when the ice near you starts to melt very rapidly. A surge of meltwater flows into the ocean. Surprisingly, you watch the sea level fall—not rise......»»

The World Is Ignoring the Other Deadly Kind of Carbon
Not only is black carbon terrible for human health, but ever-fiercer wildfires are covering the Arctic with the dark particles, accelerating melting......»»
Satellite radar data uncover "vigorous melting" at Antarctica"s Thwaites Glacier
A team of glaciologists led by researchers at the University of California, Irvine used high-resolution satellite radar data to find evidence of the intrusion of warm, high-pressure seawater many kilometers beneath the grounded ice of West Antarctica.....»»
Alaska"s rusting waters: Pristine rivers and streams turning orange
Dozens of Alaska's most remote streams and rivers are turning from a crystal clear blue into a cloudy orange, and the staining could be the result of minerals exposed by thawing permafrost, finds new research in Communications Earth & Environment......»»
Stunning images of Jupiter’s moon Europa show it has a floating icy shell
NASA's Juno mission has imaged Jupiter's intriguing moon Europa, a top target of habitability research due to its liquid water ocean beneath a thick icy crust......»»
Discovery may explain why Egyptian pyramids were built along long-lost Ahramat branch of the Nile
Some 31 pyramids in Egypt, including the Giza pyramid complex, may originally have been built along a 64-km-long branch of the river Nile which has long since been buried beneath farmland and desert. The findings, reported in a paper in Communication.....»»
New GPS-based method can measure daily ice loss in Greenland
When the ice sheet in Greenland melts, as it has done increasingly in recent years, the bedrock beneath moves slightly......»»
Thirsty in paradise: Water crises are a growing problem across the Caribbean islands
In the popular imagination, the Caribbean is paradise, an exotic place to escape to. But behind the images of balmy beaches and lush hotel grounds lies a crisis, the likes of which its residents have never experienced......»»
Hubble Space Telescope glimpses spiral galaxy UGC 9684
The celestial object showcased in this image from the NASA/ESA Hubble Space Telescope is the spiral galaxy UGC 9684, which lies around 240 million light-years from Earth in the constellation Boötes. This image shows an impressive example of several.....»»
Grizzlies are returning to Washington"s North Cascades. How will that work?

Shining a light on untapped lunar resources
Near the moon's south pole lies a 13-mile wide, 2.5-mile-deep crater known as Shackleton, named for Antarctic explorer Ernest Shackleton. Shackleton—and craters like it—may contain untapped resources that can be accessed with lunar mining......»»
Lake tsunamis pose significant threat under warming climate
Cowee Creek, Brabazon Range, Upper Pederson Lagoon—they mark the sites of recent lake tsunamis, a phenomenon that is increasingly common in Alaska, British Columbia and other regions with mountain glaciers......»»
Abrupt permafrost thaw found to intensify warming effects on soil CO₂ emission
According to a recent study published in Nature Geoscience, scientists have found that soil carbon dioxide (CO2) emissions are more sensitive to climate warming in permafrost-collapsed areas than in non-collapsed areas......»»
Cichlid fishes" curiosity promotes biodiversity: How exploratory behavior aids in ecological adaptation
Cichlid fishes exhibit differing degrees of curiosity. The cause for this lies in their genes, as reported by researchers from the University of Basel in the journal Science. This trait influences the cichlids' ability to adapt to new habitats......»»
A better way to predict Arctic riverbank erosion
Arctic riverbanks are typically resilient, thanks to the power of permafrost. This permanently frozen soil locks in sediment, leading to low erosion rates. But as Arctic river water warms due to climate change, some researchers worry that riverbanks.....»»
Hidden biosphere discovered beneath world"s driest hot desert
In a finding with implications for the search for extraterrestrial life, researchers have discovered microbial life 13 feet below Earth's most inhospitable desert. The research is published in the journal PNAS Nexus......»»
