UChicago-led study tests neural networks’ ability to handle ‘gray swan’ events Increasingly powerful AI models can make short-term weather forecasts with surprising accuracy. But neural networks only predict based on patterns from the past—what happens when the weather does something that’s unprecedented in recorded history? A new study led by scientists from the University of Chicago, in collaboration with New York University and the University of California Santa Cruz, is testing the limits of AI-powered weather prediction. In research published May 21…
UV radiation fluctuates amid wet-dry extremes in clear water bodies Lake Tahoe is experiencing large-scale shifts in ultraviolet radiation (UV) as climate change intensifies wet and dry extremes in the region. That is according to a study led by the University of California, Davis’ Tahoe Environmental Research Center and co-leading collaborator Miami University in Ohio. For the study, published in ASLO, the journal of the Association for the Sciences of Limnology and Oceanography, scientists analyzed an 18-year record of underwater irradiance…
CORVALLIS, Ore. – A novel analysis suggests more than 3,500 animal species are threatened by climate change and also sheds light on huge gaps in fully understanding the risk to the animal kingdom. The study was published today in BioScience. “We’re at the start of an existential crisis for the Earth’s wild animals,” said Oregon State University’s William Ripple, who led the study. “Up till now, the primary cause of biodiversity loss has been the twin threats of overexploitation and…
Efforts to limit the global temperature increase to 1.5°C under the Paris Climate Agreement may not go far enough to save the world’s ice sheets, according to a new study. Research led by Durham University, UK, suggests the target should instead be closer to 1°C to avoid significant losses from the polar ice sheets and prevent a further acceleration in sea level rise. The team reviewed a wealth of evidence to examine the effect that the 1.5°C target would have…
As wildfires continue to ravage regions from Los Angeles to South Korea, a new study featured on the cover of the Issue 7, 2025 of Advances in Atmospheric Sciences sheds light on the large-scale climate patterns influencing these devastating global extreme events. The research, led by Professor Young-Min Yang from Jeonbuk National University, reveals how tropical climate phenomena like the Madden-Julian Oscillation (MJO) can trigger dry, windy conditions that exacerbate wildfires in mid-latitude regions, including the western U.S. and East Asia. Wildfire…
New research reveals mountain glaciers across the globe will not recover for centuries – even if human intervention cools the planet back to the 1.5°C limit, having exceeded it. The research, led by the University of Bristol in the UK and the University of Innsbruck in Austria, presents the first global simulations of glacier change up to 2500 under so-called ‘overshoot’ scenarios, when the planet temporarily exceeds the 1.5°C limit up to 3°C before cooling back down. The results, published…
The Amazon rainforest may be able to survive long-term drought caused by climate change, but adjusting to a drier, warmer world would exact a heavy toll, a study suggests. The findings show that adjusting to cope with the effects of climate change could see some parts of the Amazon rainforest lose many of its largest trees. This would release the large amount of carbon stored in these trees to the air, and reduce the rainforest’s immediate capacity to act as…
VENICE – A team of researchers led by Niccolò Maffezzoli, “Marie Curie” fellow at Ca’ Foscari University of Venice and the University of California, Irvine, and an associate member of the Institute of Polar Sciences of the National Research Council of Italy, has developed the first global model based on artificial intelligence to calculate the ice thickness distribution of all the glaciers on Earth. The model has been published in the journal Geoscientific Model Development and is expected to become…
Discovery of 20,000-year-old cave sediments on Prince of Wales Island offers rare land-based evidence of ancient meltwater events Paul Wilcox, a geologist at the University of Innsbruck, has discovered the first land-based evidence of meltwater pulses from the Cordilleran Ice Sheet during the last ice age about 20,000 years ago. The age of the cave sediments was constrained via optical dating techniques, which is crucial to help piece together the sequence of climate events leading to a warming planet. The…
Palaeontologists at the Manitoba Museum and Royal Ontario Museum (ROM) have discovered a remarkable new 506-million-year-old predator from the Burgess Shale of Canada. The results are announced in a paper in the journal Royal Society Open Science. Mosura fentoni was about the size of your index finger and had three eyes, spiny jointed claws, a circular mouth lined with teeth and a body with swimming flaps along its sides. These traits show it to be part of an extinct group…
In the modern world, a reliable supply of hydrogen gas is vital for the function of society. Fertiliser produced from hydrogen contributes to the food supply of half the global population, and hydrogen is also a key energy component in many roadmaps to a carbon neutral future, essential if we are to prevent the worst predictions of climate change. Today, hydrogen is produced from hydrocarbons, with waste gases contributing to 2.4% of global CO2 emissions. Demand for hydrogen is set…
Originally from South America, the charismatic tegu made its way to the United States via the pet trade of the 1990s. After wreaking havoc in Florida’s ecosystems, the exotic lizard was classified as an invasive species. But a recent discovery from the Florida Museum of Natural History reveals the reptiles are no strangers to the region — tegus were here millions of years before their modern relatives arrived in pet carriers. Described in a new study in the Journal of…
Central Asia, located in the heart of the Eurasian continent, has experienced significant climatic shifts in recent decades, characterized by warming and increased humidity. This trend contrasts sharply with the global pattern of drought-induced tree growth decline, making Central Asia a unique region for studying the impacts of climate change on forest ecosystems. Alpine forests in this region are critical for regional water reserves and ecological stability and are the origins of many inland rivers such as Amu Darya and…
New research reveals that shifts in plant life played a key role in speeding up major climate changes during the late Miocene, a period spanning 11.6 to 5.3 million years ago. During this time, Earth’s climate shifted from the warm conditions of the middle Miocene to conditions closer to what we experience today, turning forests into grasslands and forcing animals like horses and elephants to evolve tougher teeth for eating gritty plants. At the same time, predators like big cats…
Individually, Antarctic krill (Euphausia superba) do not make much of an impression. With a maximum body length of six centimetres, a weight of just two grams and its transparent skin, it does not look very spectacular. Yet krill play a central role for life in the Southern Ocean. Billions of these small crustaceans form huge swarms that can extend over several square kilometers and are the most important food source for many predators. A research team from Julius-Maximilians-Universität Würzburg (JMU),…
Tyrannosaurus rex evolved in North America, but its direct ancestor came from Asia, crossing a land bridge connecting the continents more than 70 million years ago, according to a new study led by UCL researchers. The study, published in Royal Society Open Science, also found that the rapid growth in size of tyrannosaurids (the group that included the T. rex) as well as a closely related group called megaraptors coincided with a cooling of the global climate following a peak…
