• Forecasting tornado risk three weeks ahead is becoming possible

    Early results from SWERVE show that forecasts in weeks two and three can sometimes detect meaningful signals of heightened severe weather activity. The signals, produced through consensus forecasts that blend multiple models, perform better than climatology alone. Instead of simply repeating seasonal averages, they highlight specific windows when the atmosphere appears more favorable than normal…

  • Research explains link between X-rays, gamma rays, and lightning initiation

    A study published in the Journal of Geophysical Research finds that strong electric fields in thunderclouds can accelerate electrons, creating runaway avalanches that emit X-rays and gamma rays, a process connected to the conditions that lead to lightning initiation.

  • Earth’s 6-year day-length oscillation briefly faltered in 2010

    A study published in Geophysical Journal International on August 28, 2025 finds that a normally persistent 6-year oscillation in Earth’s length-of-day broke down between 2010 and 2014, with a short-lived 4.7-year interval, and that the event is contemporaneous with changes in geomagnetic field behaviour and core-flow models.

  • Study shows Earth’s carbon thermostat can overshoot, triggering ice ages

    Researchers at the University of California, Riverside, published a study in Science on September 25, 2025, showing that Earth’s long-term carbon regulation system can sometimes overcorrect. Their model suggests that warming events may, under certain conditions, tip into ice-age–scale cooling over hundreds of thousands of years.

  • Intense earthquake swarm beneath Santorini and Kolumbo volcano caused by magma intrusion

    More than 28 000 earthquakes shook Santorini and neighboring islands between late January and February 2025. At the time, the cause was only speculated, but a new Nature study led by GFZ and GEOMAR shows the swarm resulted from a mid-crustal dike intrusion that linked Santorini and Kolumbo.
