"Devastating" melt of Greenland, Antarctic ice sheets found
The Greenland and Antarctic ice sheets are now losing more than three times as much ice a year as they were 30 years ago, according to a new comprehensive international study......»»
Iron snow ebb and flow may cause magnetic fields to come and go
Just as snow crystals form in the upper atmosphere, then fall to lower, warmer elevations and melt, scientists believe a phenomenon called iron snow happens in the molten iron cores of some planetary bodies. Cooling near the core-mantle boundary crea.....»»
Avian influenza has killed millions of seabirds around the world: Antarctica could be next
Antarctica is often imagined as the last untouched wilderness. Unfortunately, avian influenza ("bird flu") is encroaching on the icy continent. The virus has already reached the sub-Antarctic islands between the Antarctic Peninsula and South America......»»
What octopus DNA tells us about Antarctic ice sheet collapse
If we want to understand the future, it's often useful to look at the past. And even more useful if you use octopus DNA to peer into worlds long gone......»»
Antarctic octopus DNA reveals ice sheet collapse closer than thought
Scientists investigating how Antarctica's ice sheets retreated in the deep past have turned to an innovative approach: studying the genes of octopuses that live in its chilly waters......»»
Vaccinating livestock against common diseases is a form of direct climate action, say researchers
Animal diseases have a devastating impact on livestock production. In 2022, for example, 131 million domestic poultry died or was culled as a result of avian influenza (also called "bird flu")......»»

Antarctic krill head south: Scientists fear the movement will have a negative impact on predators
Some populations of Antarctic krill are shifting south, closer to Antarctica, as ocean warming and sea-ice changes alter their habitat. Scientists fear the movement of krill will have a negative impact on predators like whales, seals and penguins, an.....»»

North America"s first people may have arrived by sea ice highway as early as 24,000 years ago
One of the hottest debates in archaeology is how and when humans first arrived in North America. Archaeologists have traditionally argued that people walked through an ice-free corridor that briefly opened between ice sheets an estimated 13,000 years.....»»
Myrtle rust is devastating Australian forests: New high-tech spray holds out hope for native trees
Around a decade ago, an invasive fungal disease called myrtle rust reached Australia and began to spread like a plague through certain plants. The disease affects plants of the Myrtaceae family, which includes eucalypts, paperbarks and lilly pillies,.....»»
Puerto Rico case study sheds light on academic-NGO collaborations for disaster resilience
Puerto Rico has faced several human-made and natural crises in recent years, including the devastating effects of Hurricane Maria in 2017. Building disaster resilience and recovery is crucial for community well-being and requires a comprehensive appr.....»»
The hidden impacts of climate change on a freshwater ecosystem
From melting glaciers to rising sea levels, from raging wildfires to devastating floods, society has grown increasingly aware of the increasingly frequent climate crises. But what about its subterranean flow? A research group led by Li Dongfeng at th.....»»
Researchers: Frozen methane under the seabed is thawing as oceans warm, and things are worse than we thought
Buried beneath the oceans surrounding continents is a naturally occurring frozen form of methane and water. Sometimes dubbed "fire-ice" as you can literally set light to it, marine methane hydrate can melt as the climate warms, uncontrollably releasi.....»»
Coral reefs in peril from record-breaking ocean heat
Record breaking marine heat waves will cause devastating mass coral bleaching worldwide in the next few years, according to a University of Queensland coral reef scientist......»»
Research pieces ancient ecosystems together to reveal new details about the end-Triassic mass extinction
Startling new insights into the catastrophic impact of one of the most devastating events in Earth's history have been revealed by a team led by researchers with the USC Dornsife College of Letters, Arts and Sciences. More than deepening our understa.....»»
Novel viral treatment found to be effective against devastating bone cancer in dogs
Researchers from the University of Minnesota partnered with Mayo Clinic to conduct a groundbreaking study that could offer hope for dogs, and potentially humans, diagnosed with osteosarcoma— a devastating bone cancer predominantly affecting childre.....»»
Understanding climate tipping points
As the planet warms, many parts of the Earth system are undergoing large-scale changes. Ice sheets are shrinking, sea levels are rising and coral reefs are dying off......»»
Do terrorist attacks and mass shootings make big companies more "honest"?

British research ship crosses paths with world"s largest iceberg as it drifts out of Antarctica
Britain's polar research ship has crossed paths with the largest iceberg in the world—a "lucky" encounter that enabled scientists to collect seawater samples around the colossal berg as it drifts out of Antarctic waters, the British Antarctic Surve.....»»
Q&A: Can scientific ingenuity turn the clock back on climate change?
The summer of 2023 was the hottest on record. Climate change fueled destructive hurricanes in Florida, more intense monsoons in India, and melted sea ice to historically low levels in the Arctic and Antarctic......»»
