World models are emerging as one of the most important directions in artificial intelligence research. Unlike large language models such as ChatGPT, Claude, and Gemini, which predict the next word in a sequence of text, world models are designed to learn how real systems behave by observing data and simulating future outcomes. Rather than modeling language alone, they aim to represent the dynamics of the physical world. Researchers including Yann LeCun, Demis Hassabis, Fei-Fei Li, and Jensen Huang view this approach as a foundation for the next generation of AI, although experts note that not every system described as a world model meets the strict technical definition.

For more than 100 million years, Earth has maintained a natural climate regulation system that has helped keep the planet habitable despite major environmental changes. A new study published in the Proceedings of the National Academy of Sciences identifies a previously overlooked relationship between sea level, ocean phosphate, and long-term carbon storage that helps explain how Earth’s carbon cycle has regulated atmospheric carbon dioxide over the past 60 million years. The research suggests that fluctuations in sea level influenced marine nutrient availability, biological productivity, and the burial of organic carbon, creating a powerful natural feedback that affected global climate.

The European Digital Twin Ocean is an ambitious initiative designed to create a living, interactive digital replica of the ocean that will improve scientific understanding and support better environmental decision-making. Funded by the European Commission and supported by the Copernicus Marine Service and the European Marine Observation and Data Network (EMODnet), the project combines vast amounts of real-time and historical ocean data into a unified digital environment. By integrating information collected from satellites, ocean sensors, research vessels, computer models, and even smartphone applications, the platform will enable users to monitor current ocean conditions while exploring possible future scenarios. The system is expected to be fully operational by 2030.

A major scientific expedition to Greenland is preparing to deploy an advanced fleet of robots, drones, autonomous submarines, and sensors to study glacier melting where ice meets the ocean. The project, known as GIANT (Greenland Ice sheet to AtlaNtic Tipping points from ice loss), is funded by the United Kingdom’s Advanced Research and Invention Agency with approximately £20 million. Researchers aim to collect unprecedented observations of glacier-ocean interactions that have previously been too dangerous and technically challenging to measure. The data will improve climate models and help scientists better understand how melting ice could influence global climate systems.

A new study published in Science provides fresh insight into the geological processes that generate and sustain the enormous volcanic systems responsible for Earth’s largest eruptions. Scientists from the Institute of Geology and Geophysics of the Chinese Academy of Sciences developed a three-dimensional geodynamic model of western North America to investigate how magma forms beneath the Yellowstone region. Their findings offer a new explanation for the evolution of a supervolcano, challenging several long-standing ideas about how these massive volcanic systems operate beneath the Earth’s surface.

A rare seismic doublet struck northwestern Venezuela on 24 June 2026, producing two powerful earthquake events within just 39 seconds of one another. Unlike a typical sequence in which a large mainshock is followed by smaller aftershocks, a seismic doublet consists of two earthquakes of nearly equal magnitude that occur close together in both time and location. Scientists identify these events because they originate from the same rupture area, share similar seismic waveforms, and differ by only a small amount in magnitude.

Ocean currents play a fundamental role in regulating Earth’s climate by transporting heat, moisture, and nutrients around the planet. These continuous flows of seawater redistribute solar energy from the tropics toward the poles, helping determine regional temperatures, rainfall patterns, and weather conditions. Driven by a combination of wind, Earth’s rotation through the Coriolis effect, and differences in water temperature and salinity, these interconnected flows form a global circulation system that links every major ocean basin. Surface currents are primarily wind-driven, while deep currents are powered by variations in water density, together moving enormous amounts of heat across the globe.

A new study published in Geophysical Research Letters suggests that intense solar activity may influence Earth’s weather far more quickly than previously understood. While scientists have long known that the Sun’s approximately 11-year activity cycle affects Earth’s atmosphere over extended periods, the latest research indicates that geomagnetic storms can trigger measurable weather changes within hours or days. These findings provide new insight into the complex relationship between space weather and atmospheric conditions on Earth.

Heatwaves across Europe and South Asia have recently drawn global attention, but scientists emphasize that these extreme weather events are symptoms of a deeper and more significant trend: the rapid accumulation of heat within the Earth’s climate system. According to a new assessment by an international team of climate researchers, Earth’s energy imbalance has reached record levels and has doubled over recent decades. This imbalance refers to the difference between the amount of solar energy entering the planet and the amount of energy escaping back into space. In a stable climate, these values would be roughly equal. However, increasing concentrations of greenhouse gases have disrupted this balance, causing the Earth to retain more heat than it releases.

A new study has found that tectonic stress on Southern California’s major fault systems has reached exceptionally high levels, raising important questions about future earthquake hazards in one of the most heavily populated regions of the United States. Researchers examined the San Andreas and San Jacinto fault systems and concluded that stress accumulation along parts of these faults is now greater than at any point during the last 1,000 years, with some segments potentially exceeding previous historical levels.
