A study predicts that increasing ice melt could lead to abrupt changes in the Atlantic Meridional Overturning Circulation (AMOC), potentially collapsing it even if freshwater influx remains below a critical threshold. The system's chaotic dynamics make predicting tipping points challenging.
A new study finds that atmospheric rivers in the Southern Hemisphere are shifting toward the South Pole, which could lead to increased rates of ice melt in Antarctica. The shift is driven by a combination of factors, including ozone depletion, greenhouse gas emissions, and natural variations in sea surface temperature.
Melting of 'eternal ice' patches in northern Mongolia poses a significant threat to traditional reindeer herding and exposes fragile cultural artifacts to the elements. The study, published in PLOS ONE, highlights the urgent need to address global climate change's impact on Inner Asia.
New research from Mongolia uncovers historic tool production and wild resource use, shedding light on premodern reindeer domestication. However, the study also highlights the devastating impact of climate change on modern reindeer herders' livelihoods and cultural heritage.
An international team of scientists used structured expert judgment to estimate plausible ranges for future sea level rise from melting ice sheets. Their findings suggest that coastal communities should not rule out the possibility of 21st-century SLR in excess of two metres when developing adaptation strategies.
A global study found that melting glaciers worldwide have caused a significant increase in global sea levels over the past 30 years, with 19,000 glaciers losing an average of 27 millimeters of ice since 1961. The largest contributors were glaciers in Alaska and Patagonia, resulting in a 335 billion-ton annual loss of glacier ice.
The study found that the largest sustained ice loss in Greenland came from summertime melting of the southwest region, which has few glaciers. The researchers linked this to a climate cycle called the North Atlantic Oscillation. As global warming continues, the southwest region will become a major contributor to sea level rise.
Quantitative analysis reveals that dark ocean surfaces absorb more light than white ice surfaces, leading to accelerated sea ice melt. The study found a significant correlation between solar heat input and ice melt volume, suggesting that heat input is a major causative factor of melting ice.
Research reveals that strengthening winds in East Antarctica generate Kelvin waves that lead to increased melting along the West Antarctic Peninsula. This warming can drive up to 1°C of water temperature, contributing to significant ice shelf melt and potential sea-level rise.
A team of earth scientists evaluated how various processes affect past measurements, revealing that many high-quality historical records are from locations with reduced local sea level change compared to the global average. This suggests a minimum 14cm increase in global sea level rise during the 20th century.
Researchers analyzed deep sea coral samples to reveal that past carbon dioxide spikes occurred alongside high ocean circulation events. The findings suggest that excess carbon in the deep ocean was flushed out, releasing CO2 into the atmosphere.
New research reveals polar bears' metabolic rates remain high during summer ice melt, limiting their ability to conserve energy. The study suggests that as sea ice loss increases, polar bears are unable to adapt by entering a low-energy state, leaving them vulnerable to food shortages and reduced survival rates.
Scientists recorded and identified the sizzling sound of glacier ice as it melts, a phenomenon caused by trapped air bubbles escaping from the disappearing ice. This discovery could help researchers better monitor polar environments and track changes in glacier melt rates using underwater hydrophone recordings.
A new 1000-year Antarctic Peninsula climate reconstruction reveals a near-tenfold increase in summer ice melt since the mid-20th century. This intensification has important implications for ice instability and sea level rise in a warming climate.
A new study published in Nature Geoscience reveals that Arctic methane seepage is linked to melting ice caps, causing climate warming and sea level rise. This phenomenon could lead to significant shoreline retreat and erosion along the Florida coastline, posing a serious threat to coastal residents and infrastructure.
A recent study led by University of Georgia biogeochemist Wei-Jun Cai found that the Canada Basin's potential as a carbon dioxide sink is short-lived and minor. The research indicates that the waters become acidic and unsuitable for calcium-carbonate shell-bearing marine organisms due to rapid CO2 uptake.
Scientists from the University of Miami found that Greenland's ice is melting rapidly, causing the land underneath to rise by nearly one inch per year. The study suggests that if current trends continue, this acceleration could lead to a significant increase in global sea level rise.
Researchers found that small increases in carbon dioxide led to substantial global warming about 4.5 million years ago. Slow changes in ice sheets and other factors amplify the effects of greenhouse gas composition.
Scientists have discovered that parts of Antarctic bedrock are rising while others sink in response to melting ice. This finding will improve estimates of future sea level rise by providing a better view of what's happening under the ice.
