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.....»»
Melting ice no guarantee of smooth sailing in fabled Arctic crossing: Study
Melting sea ice in the fast-warming Arctic Ocean is not making it easier for sailors to navigate a legendary shortcut between Europe and Asia despite popular belief, scientists said Thursday......»»
Investigating variation in the permafrost active layer over the Tibetan Plateau from 1980 to 2020
The Tibetan Plateau hosts the world's largest permafrost region in the middle and low latitudes. Compared to the high-latitude Arctic permafrost, the permafrost here is thinner, warmer, and more sensitive to global warming. The active layer is a cruc.....»»
Melting high-mountain glaciers would release greenhouse gases into atmosphere, suggest scientists
The retreat of high mountain glaciers has accelerated since the 1980s, resulting in increased glacier runoff. However, it remains uncertain whether melting mountain glaciers enhance or release greenhouse gases, and whether areas exposed to glacier re.....»»
Studies unravel climate pattern impacts on the Antarctic Ice Sheet
New Monash research has untangled the influence of regional climate drivers, including the Southern Annular Mode (SAM) and the El Niño-Southern Oscillation (El Niño), on the Antarctic Ice Sheet. Snow accumulation and surface melting are two importa.....»»
Scientists call for "major initiative" to study whether geoengineering should be used on glaciers
A group of scientists have released a landmark report on glacial geoengineering—an emerging field studying whether technology could halt the melting of glaciers and ice sheets as climate change progresses......»»

Pest predictor identifies ingredients for ecological recipe for destruction
If you've felt the familiar itch of browntail moth rash, seen the grayish-green needles of an infested hemlock or watched as woodpeckers bore into ash trees for a meal hidden beneath the surface, you've experienced the devastating effects of non-nati.....»»
Scientists track sea level rise from glaciers in Greenland and Antarctica
As climate change advances, the vast bodies of ice on Antarctica and Greenland contribute significantly to sea level rise. To project their future effect on sea level rise, additional research is required to improve scientists' understanding of these.....»»
Researchers use 1,000 historical photos to reconstruct Antarctic glaciers before a dramatic collapse
In March 2002, the Larsen B Ice Shelf collapsed catastrophically, breaking up an area about one-sixth the size of Tasmania......»»
Alaska’s top-heavy glaciers are approaching an irreversible tipping point
As the plateau of the icefield thins, ice and snow reserves at higher altitudes are lost. Enlarge / Taku Glacier is one of many that begin in the Juneau Icefield. (credit: Mauricio Handler / Getty Images) The melting of.....»»
Alaska"s top-heavy glaciers are approaching an irreversible tipping point
The melting of one of North America's largest icefields has accelerated and could soon reach an irreversible tipping point. That's the conclusion of new research colleagues and I have published on the Juneau Icefield, which straddles the Alaska-Canad.....»»
Whether children lie depends on the social environment, says study
Everyone lies—some more, some less. Children are no different. An international team of economists has now investigated the influence of the parental home and upbringing on a child's propensity to lie......»»
Recovery of unique geological samples sheds light on formation of today"s Antarctic ice sheet
In recent years, global warming has left its mark on the Antarctic ice sheets. The "eternal" ice in Antarctica is melting faster than previously assumed, particularly in West Antarctica more than East Antarctica. The root for this could lie in its fo.....»»
Treasures beneath the ocean floor? Seawater plays role in gold formation
Understanding how gold forms is crucial for knowing where to find it and how to extract it sustainably. McGill researchers have answered a long-standing question in geology that could lead to new ore discoveries......»»
Discovering a new piranha species in the Amazon Basin
Have you ever wondered what secrets the Amazon Basin holds beneath its murky waters? I'm Flavio Gallo Cardozo, a biologist from Bolivia, and I'm excited to share with you the journey of discovering a new piranha species, Serrasalmus magallanesi, from.....»»
NASA mission flies over Arctic to study sea ice melt causes
It's not just rising air and water temperatures influencing the decades-long decline of Arctic sea ice. Clouds, aerosols, even the bumps and dips on the ice itself can play a role. To explore how these factors interact and impact sea ice melting, NAS.....»»
Microscopic defects in ice influence how massive glaciers flow, study shows
As they seep and calve into the sea, melting glaciers and ice sheets are raising global water levels at unprecedented rates. To predict and prepare for future sea-level rise, scientists need a better understanding of how fast glaciers melt and what i.....»»
Researchers investigate changes in surface heat fluxes on sensitive areas for the slopes of Mt Everest
Under the background of global warming, the Mount Everest region has experienced evident climate changes. Glaciers and snow have been rapidly retreating in this region. These changes increase the rate of warming and water scarcity in downstream areas.....»»
New research shows soil microorganisms could produce additional greenhouse gas emissions from thawing permafrost
As the planet has warmed, scientists have long been concerned about the potential for harmful greenhouse gases to seep out of thawing Arctic permafrost. Recent estimates suggest that by 2100 the amount of carbon dioxide and methane released from thes.....»»
Buried kelp: Seaweed carried to the deep sea stores more carbon than we thought
Deep in the ocean lies the world's largest active carbon reservoir, which plays a pivotal role in buffering our planet's climate. Of the roughly 10 billion metric tons of carbon dioxide we emit each year, about 3 billion metric tons are taken up and.....»»
