This phenomenon could occur worldwide, including Antarctica, and may have global climate impacts, including long-term warming.

Researchers found a strong association between helium and groundwater, suggesting that large volumes of helium are being transported into natural gas fields. This discovery indicates that the existing helium reserves may be greater than initially thought.
Researchers found that comet impacts can synthesize peptides, the first building blocks of life, under cold conditions. This suggests that comet impacts played a crucial role in delivering life's seeds to early Earth.
A new test for liver cancer is being developed based on analyzing the stable isotope compositions of rocks and minerals. The researchers found that patients with HCC have enriched quantities of certain isotopes, such as copper-63 and sulphur-32, in their blood compared to normal controls.
A new test measures changes in calcium isotope ratios to monitor bone diseases like osteoporosis and multiple myeloma. The test, validated on NASA space shuttle astronauts' blood samples, shows promise for near-time monitoring of bone health.
Coral reef scientists warn that even with a successful Paris climate conference, ocean warming and acidification will continue beyond the end of this century, potentially leading to the extinction of coral reefs. Experts call for more aggressive emissions reduction plans to stabilize CO2 at 350ppm or lower to give reefs a chance.
The six-month-long eruption produced around 1.6 km3 of lava and 12m tonnes of SO2 emissions, affecting Iceland and parts of Europe. Monitoring stations recorded high SO2 spikes in Ireland, Austria, and other countries, with levels exceeding European health limits.
Scientists have long suspected sulphur in the Earth's core but now have conclusive geochemical evidence confirming its presence and estimating its vast quantity. The discovery lends weight to the theory that the Moon was formed by a planet-sized body colliding with the Earth.
Researchers discovered that bacteria can use magnetite to create a 'natural battery' by loading and discharging electrons. This mechanism has implications for cleaning up toxic metals and could be adapted for other types of bacteria, expanding its potential uses.
Researchers have found remarkably preserved 15-million-year-old thin protein sheets in fossil shells from southern Maryland. The proteins share characteristics with modern mollusk shell proteins, offering insights into the evolution of mollusks and the ecology of the Chesapeake Bay during the mid-Miocene era.
Wally Broeker advocates for carbon capture technology to reduce global warming by capturing atmospheric CO2 and storing it underground. He argues that this approach is crucial to mitigating the effects of human activity on the environment.
Researchers discovered that subseafloor microbes have adapted to live in harsh conditions by increasing expression of DNA repair genes and cellular stress response mechanisms. This adaptation allows them to survive in environments with high pressure and nutrient scarcity, enabling them to play an important role in global elemental cycles.
Researchers find that the Earth's crust formed relatively slowly from 1.7 to 0.75 billion years ago, with little activity and stable environments, before speeding up, potentially inducing evolutionary changes. This discovery has implications for the interpretation of climate models.
A new study has found that the Western Amazon is contaminated with oil pollutants, posing a significant risk to its unparalleled biological and cultural diversity. The research, published for the first time, reveals high levels of lead, mercury, and cadmium in wastewater samples from 18 sites in 10 Amazon tributaries.
A team of French scientists has proposed a model explaining the sudden drop in atmospheric CO2 levels 300 million years ago, when a massive mountain range formed in Pangea. The formation of these mountains led to physical erosion and rock weathering, removing CO2 from the atmosphere and preventing severe greenhouse effects.
Researchers Guillaume Avice and Bernard Marty found the Earth is approximately 60 million years older than previously thought. The team analyzed xenon gas sealed in quartz samples to refine dating techniques and estimate the Moon-forming impact timing, now believed to be around 40 million years after solar system formation.
Researchers from Harvard University believe they've found signs of an ancient Earth within the Earth's mantle, challenging the theory of the Moon's formation. They analyzed noble gas isotopes and found significant differences between shallow and deep mantle regions.
Researchers have found elevated levels of oxygen-17 in lunar samples compared to Earth, providing evidence for a giant impact hypothesis. The findings suggest that the Moon formed from debris left over after a massive collision between two proto-planets.
A UK team discovered that summer meltwaters from ice sheets are rich in bioavailable iron, which boosts phytoplankton growth and captures carbon, thus buffering the effects of global warming. The researchers estimate that the flux of bioavailable iron associated with glacial runoff is between 400,000 and 2,500,000 tonnes per year.
Researchers find reversible microbial redox cycling in humic substances, which store electrons and prevent methane release. Climate change disruption could lead to vicious cycle of worsening greenhouse effect.
New research suggests that terror birds were likely herbivores, based on the analysis of calcium isotope composition in their fossilized bones. The study found that the terror bird's diet was similar to that of herbivorous mammals and dinosaurs, indicating a non-carnivorous diet.
Research shows that bacteria living in Gulf of Mexico beaches can thrive on a diet of oil by fixing nitrogen from the air, opening doors to more sophisticated cleanup techniques. However, some bacteria play an important role in the ecosystem experienced a sharp decline following the contamination.
New research presents evidence suggesting that life may have originated on Mars and was brought to Earth via a Martian meteorite. The study tackles two paradoxes related to the origin of life on Earth, including the 'tar paradox' and the difficulty in starting life due to water coverage.
