New Zealand—particularly the South Island/Te Waipounamu—is one of the most seismically active regions in the world. For this reason, the country has acknowledged the importance of building awareness and preparedness.

Online map reveals link between deforestation and rises in tropical temperatures Deforestation is leading to temperature increases of up to 5°C in some tropical regions, according to data revealed in a new interactive map created by researchers at the University of Leeds.

EU researchers are exploring how undersea communication cables can double-up as environmental and seismic sensors—a potential game-changer for early warning systems.

In the dense forests of northwestern Pennsylvania, hundreds of thousands of retired oil and gas wells—some dating back to the mid-1800s, long before modern construction standards—dot the landscape, according to geochemists in Penn State's College of Earth and Mineral Sciences who recently led a study in the region. Left uncapped and exposed to air and erosion, they break down, leaching harmful chemicals into the atmosphere and, the researchers reported, into the groundwater.

A team led by LMU researchers shows why CO₂ fluxes from land use are so difficult to quantify—and how they can be estimated more accurately in the future.

Satellite scatterometers play a crucial role in monitoring ocean surface winds, with their accuracy directly impacting weather forecasting and climate research. However, rainfall has consistently challenged precise wind measurements, as Ku-band radar signals are much affected by rain clouds.

Thwaites Glacier in West Antarctica—often called the "Doomsday Glacier"—is one of the fastest-changing ice–ocean systems on Earth, and its future remains a major uncertainty in global sea-level rise projections. One of its floating extensions, the Thwaites Eastern Ice Shelf (TEIS), is partially confined and anchored by a pinning point at its northern terminus.

Ten years on from the landmark Paris Agreement, countries have taken big strides in limiting emissions and the clean energy transition is accelerating rapidly. But geopolitical headwinds are growing and the damage bill for climate pollution is rising. Climate action hangs in the balance.

A study has revealed that the substantial retreat of the East Antarctic Ice Sheet (EAIS) approximately 9,000 years ago was driven by a self-reinforcing feedback loop between ice melt and ocean circulation.

Over the past 50 years, geographers have embraced each new technological shift in geographic information systems (GIS)—the technology that turns location data into maps and insights about how places and people interact—first the computer boom, then the rise of the internet and data-sharing capabilities with web-based GIS, and later the emergence of smartphone data and cloud-based GIS systems.

A new study led by researchers at the Lamont-Doherty Earth Observatory offers the clearest evidence yet that a centuries-long drought transformed life on Rapa Nui (Easter Island) beginning around the year 1550.
