Phys.org / Why natural forests survive heat waves better than planted forests
When a record-breaking drought and heat wave swept across China's Yangtze River Basin in 2022, forests across the region faced an extreme test. The event provided a rare opportunity for researchers to test how different forests ...
Phys.org / Antarctic ozone loss drove unexpected Southern Ocean cooling, climate model shows
The Southern Ocean has long stood out as an oddity in the global climate system. While most of the planet's surface oceans have warmed in response to rising greenhouse gases, waters circling Antarctica showed an unexpected ...
Phys.org / Coastal and estuarine carbon removal technique may backfire when pushed too far
Scientists investigating a proposed way to remove carbon dioxide from the atmosphere using seawater have found that adding too much alkalinity to neutralize acids can trigger chemical reactions that undermine the process.
Phys.org / Coal pollution reaches one of Earth's most remote mountain regions
The Himalayas are often seen as one of Earth's great natural barriers, separating the heavily populated and industrialized regions of South Asia from the remote Tibetan Plateau. But new research, published in Geophysical ...
Phys.org / Climate change reshapes Spain's rockfall risk as frost weathering moves uphill
Climate change is altering where and when rocks are most likely to fracture across Spain, according to new research that suggests warming temperatures are redistributing a key process responsible for breaking down mountain ...
Science X / Hot European summers may be predictable years in advance from North Atlantic warming
A buildup of warmth in the North Atlantic Ocean could provide an early warning that Europe is more likely to experience unusually hot summers years later, according to a new study published in Geophysical Research Letters.
Phys.org / Volcanic eruptions linked to rising famine risk across China's history
Large volcanic eruptions may have played a bigger role in triggering historical famines across China than previously understood, according to a new study that traced links between eruptions, climate disruption, and food shortages ...
Phys.org / Hidden meltwater found deep in Antarctic coastal waters reveals stronger climate impacts
Freshwater from melting Antarctic glaciers may be influencing the Southern Ocean in ways scientists have largely overlooked. New research, published in Frontiers in Marine Science, has found that glacial meltwater is not ...
Phys.org / Intensifying droughts may be pushing tropical forests toward a dangerous threshold
Tropical forests, often described as the lungs of the planet, may be edging closer to a dangerous threshold as droughts become more frequent and widespread across the world's humid tropics. New research suggests these ecosystems ...
Phys.org / Ancient Maya droughts may have been fueled by Earth's own climate swings
Dramatic droughts linked to the decline of the Classic Maya civilization approximately 800 to 1000 CE may not have required any external trigger, according to a new climate modeling study. Instead, they could have emerged ...
Phys.org / Conflict-driven farmland abandonment in Syria leads to land uplift, study finds
The Syrian civil war, which began in 2011, caused widespread population displacement and infrastructure damage. However, it has also led to an unintended environmental effect with notable changes in the country's landscape, ...
Phys.org / New index reveals global water resources' growing dependence on extreme rainfall
As global temperatures climb, rainfall patterns are shifting in ways that could put water resources and agriculture under increasing strain, a new study published in Water Resources Research suggests.
Phys.org / Rivers and tidal currents keep 80% of microfibers from reaching oceans, study suggests
Every time we do a load of laundry, tiny fibers of polyester escape from our clothes and slip down the drain. These microfibers, so small they can be invisible to the naked eye, are among the most common forms of microplastic ...
Phys.org / Models warn Thwaites Glacier could rival entire Antarctic ice loss by 2067
The future of one of Antarctica's most iconic glaciers could be far more dramatic than scientists previously thought. Using satellite calibrated ice sheet models, a team of researchers from the University of Edinburgh found ...
Phys.org / Salt may have pushed us further into Snowball Earth 700 million years ago
Our planet plunged into one of the most dramatic climate states in its long history, approximately 720–635 million years ago. During a period geologists call Snowball Earth, ice sheets crept from the poles all the way to ...
