Published Glaciers becoming smaller and disappearing



Researchers show that some glaciers have disappeared entirely, some no longer show movement, some are too small to meet the 0.01 square kilometer minimum and some are actually rock glaciers -- rocky debris with ice in the pore spaces.
Published New research reveals extreme heat likely to wipe out humans and mammals in the distant future



A new study shows unprecedented heat is likely to lead to the next mass extinction, akin to when the dinosaurs died out, eliminating nearly all mammals in some 250 million years time.
Published How weather patterns will change in the future



In a warming Pacific Northwest, summers are getting hotter and winters less cold, but the atmospheric patterns that influence the weather aren't necessarily expected to become stronger or more frequent by the end of the century, according to a new study.
Published New study definitively confirms Gulf Stream weakening, understanding the changes could help predict future trends in extreme events



The Gulf Stream transport of water through the Florida Strait has slowed by 4% over the past four decades, with a 99% certainty that this weakening is more than expected from random chance, according to a new study.
Published We could sequester CO2 by 're-greening' arid lands, plant scientists say



Reducing CO2 levels in the atmosphere will take more than cutting emissions -- we will also need to capture and store the excessive volumes of already-emitted carbon. A team of plant scientists argue that arid lands such as deserts could be one answer to the carbon-capture problem.
Published Greenwashing a threat to a 'nature positive' world



Researchers have identified the threat greenwashing poses to a 'nature positive' world, one where environmental decline halts and biodiversity outcomes improve.
Published Chicago's West Side is air pollution hotspot



The western edge of Chicago -- including the North and South Lawndale, East Garfield Park, Archer Heights and Brighton Park neighborhoods -- experiences up to 32% higher concentrations of nitrogen dioxide (NO2) air pollution compared to the rest of the city.
Published Long-lasting La Nina events more common over past century



Multiyear La Niña events have become more common over the last 100 years, according to a new study. Five out of six La Nina events since 1998 have lasted more than one year, including an unprecedented triple-year event.
Published Riddle of varying warm water inflow in the Arctic now solved



In the 'weather kitchen,' the interplay between the Azores High and Icelandic Low has a substantial effect on how much warm water the Atlantic transports to the Arctic along the Norwegian coast. But this rhythm can be thrown off for years at a time. Experts finally have an explanation for why: Due to unusual atmospheric pressure conditions over the North Atlantic, low-pressure areas are diverted from their usual track, which disrupts the coupling between the Azores High, the Icelandic Low and the winds off the Norwegian coast. This finding is an important step toward refining climate models and more accurately predicting the fate of Arctic sea ice in the face of progressing climate change.
Published Ancient Amazonians intentionally created fertile 'dark earth'



A new study suggests patches of fertile soil in the Amazon, known as dark earth, were intentionally produced by ancient Amazonians as a way to improve the soil and sustain large and complex societies.
Published A newly identified virus emerges from the deep



Marine virologists analyzed sediment from the Mariana Trench, the deepest place on Earth, and identified a new bacteriophage.
Published New research brings greater understanding of Asian winter monsoon



Scientists have discovered a new technique which will shed light on the phenomena of winter monsoons -- the heavy autumn and winter rainfalls which can cause floods and landslides across southeast Asia.
Published Researchers discover a new species of larger benthic foraminifer from the Ryukyu Islands



An international group of researchers have discovered a previously unknown species of large foraminifer, shedding new light on the ecological evolution and biodiversity of coral reefs in the Ryukyu Islands.
Published Glacier Loss Day indicates record breaking glacier melt



In the summer of 2022, one of Tyrol's largest glaciers experienced its most significant loss of mass on record. Last year, the Hintereisferner in Tyrol, Austria, reached its Glacier Loss Day (GLD) earlier than ever before. The GLD serves as an indicator of a glacier's health throughout the year, similar to how the Earth Overshoot Day measures Earth's resource consumption.
Published Crucial third clue to finding new diamond deposits


Researchers studying diamond-rich rocks from Western Australia's Argyle volcano have identified the missing third key ingredient needed to bring valuable pink diamonds to the Earth's surface where they can be mined, which could greatly help in the global hunt for new deposits.
Published Incubator or barrier? Exploring the links between agriculture, biodiversity and the spread of pathogens


Many pathogens, including the virus that causes COVID-19, are thought to have originated in wild animals before spilling into human populations.
Published Study finds significant chemical exposures in women with cancer



Exposure to endocrine-disrupting chemicals like PFAS and phenols are implicated in hormone-mediated cancers of the breast, ovaries, skin and uterus. To learn more about the environmental exposures experienced by women who developed these cancers, researchers analyzed data from NHANES and found that women who reported having cancer had significantly higher levels of these chemicals in their bodies.
Published Earth's stability and ability to support civilization at risk: Six of nine planetary boundaries exceeded



A new study updates the planetary boundary framework and shows human activities are increasingly impacting the planet and, thereby, increasing the risk of triggering dramatic changes in overall Earth conditions.
Published Electrifying vehicles in Chicago would save lives, reduce pollution inequities


If the Chicago region replaced 30% of all on-road combustion-engine vehicles -- including motorcycles, passenger cars and trucks, buses, refuse trucks and short- and long-haul trucks -- with electric versions, it would annually save more than 1,000 lives and over $10 billion, according to a new study.
Published New research reveals why and when the Sahara Desert was green



A pioneering study has shed new light on North African humid periods that have occurred over the past 800,000 years and explains why the Sahara Desert was periodically green.
