Earthquake forecasting tools powered by AI can forecast the risk of aftershocks seconds after the initial tremor, a new study suggests. The machine learning models can forecast where, and how many, aftershocks will take place following an earthquake in close to real-time, researchers say.

Many ecosystems on Earth are affected by pulses of activity: temperature swings between seasons, incoming and outgoing tides, the yearly advent of rainy periods. These variations can play an important role in providing nutrients and other important inputs, but climate change often makes the amplitude of these pulses more extreme, with sometimes catastrophic results.

Florida State University oceanographers have discovered a significant connection between small-scale microbial processes and ecosystem-wide dynamics, offering new insights into the mechanisms driving marine carbon storage.

Climate change is accelerating the reorganization of river-lake systems on the Qinghai-Tibet Plateau, reshaping hydrological and ecological processes in the "Asian Water Tower."

Sixty-million-year-old rock samples from deep under the ocean have revealed how huge amounts of carbon dioxide are stored for millennia in piles of lava rubble that accumulate on the seafloor.

Tropical cyclones can unleash extensive devastation, as recent storms that swept over Jamaica and the Philippines made unmistakably clear. Accurate weather forecasts that buy more time to prepare are crucial for saving lives and are rooted in a deeper understanding of climate systems.

A University of Houston scientist has teamed with international partners to examine how Antarctica's massive glaciers are shifting and how that could predict sea level changes. Their latest collaboration offers the most precise mapping to date in Antarctica of grounding lines, the points where glaciers lift from bedrock and begin to float on the ocean.

Despite continuous efforts to evaluate and predict changes in Earth's climate, most models still struggle to accurately simulate extreme precipitation events. Models like the Coupled Model Intercomparison Project Phases 5 and 6 (CMIP5 and CMIP6) use fairly coarse resolution due to computing constraints, making it a little easier, faster and less expensive to run simulations, while still providing some degree of accuracy.

New study reveals burning of fossil fuels is accelerating winter rainfall changes in the UK and Europe, almost 25 years sooner than expected.

An international team of scientists and students, led by the Arctic University of Norway, and including chemists and engineers from Woods Hole Oceanographic Institution, has announced a remarkable discovery of a venting system on the seafloor of the Arctic. This significant finding was made during the ongoing EXTREME25 expedition aboard the research vessel Kronprins Haakon.

Research led by polar scientists from Northumbria University has revealed new hope in natural environmental systems found in East Antarctica which could help mitigate the overall rise of carbon dioxide in the atmosphere over long timescales.

The Atlantic Meridional Overturning Circulation (AMOC), a system of Atlantic Ocean currents that redistributes heat and nutrients between the tropics and the North Atlantic, is one of the planet's tipping points. That means there is a critical threshold that, once crossed, could trigger abrupt, irreversible climate shifts.

This year's COP30 comes after the international Agreement on Marine Biological Diversity of Areas beyond National Jurisdiction (BBNJ) finally acquired the required number of ratification votes by United Nations member states.

When militia attacks disrupted shipping lanes in the Red Sea, few imagined the ripple effects would reach the clouds over the South Atlantic. But for Florida State University atmospheric scientist Michael Diamond, the rerouting of cargo ships offered a rare opportunity to clarify a pressing climate question—How much do cleaner fuels change how clouds form?

The varied topography of the Western United States—a patchwork of valleys and mountains, basins and plateaus—results in minutely localized weather. Accordingly, snowfall forecasts for the mountain West often suffer from a lack of precision, with predictions provided as broad ranges of inch depths for a given day or storm cycle.

ACM, the Association for Computing Machinery, today presented a 26-member team with the ACM Gordon Bell Prize for Climate Modeling in recognition of their project "Computing the Full Earth System at 1 km Resolution." The award honors innovative contributions to parallel computing toward solving the global climate crisis.

Who owns the rainforest—and who has the right to use it—might seem like a simple question.

Why do some earthquakes release more energy than others? A research team led by Prof. Dr. Armin Dielforder from the University of Greifswald has managed to demonstrate a clear physical connection between the energy released during earthquakes and the strength of rocks deep in the Earth's crust.

As a result of climate change, rising sea levels are threatening low-lying coastal areas around the world, such as the Wadden Sea in the North Sea. Tidal basins form a natural protective barrier there. They connect the mainland with the offshore islands. They fill with seawater during high tide and empty again during low tide. Sediments are deposited in the process, causing the seabed to rise steadily.

The explosiveness of a volcanic eruption depends on how many gas bubbles form in the magma—and when. Until now, it was thought that gas bubbles were formed primarily when the ambient pressure dropped while the magma was rising.
