    1530. “Hydrologic Whiplash”: Accelerating Swings Between Wet and Dry Under Climate Change

    With the progression of climate change, extreme events in which droughts and floods rapidly alternate over short periods are increasingly being reported worldwide. These abrupt swings between dry and wet conditions are referred to as hydrologic whiplash and are gaining attention as a framework that integrates water-related hazards that have traditionally been analyzed separately. A perspective article published in Proceedings of the National Academy of Sciences (PNAS) introduces this concept and discusses its recent trends.

    1529. Year-Round Marine Heatwaves as an Emerging Risk: Impacts on Marine Ecosystems at ~1.5°C Warming

    In recent years, anomalously high ocean temperatures—commonly referred to as marine heatwaves—have shown clear trends of expanding spatial extent, increasing intensity, and longer duration. These changes are already having significant impacts on marine ecosystems and the societies that depend on them. A recent study published in One Earth examines the record-breaking warm period from 2023 to 2024 and demonstrates that these impacts are occurring throughout the year rather than being confined to specific seasons.

    1528．Earth System Tipping Points: A New Warning on the Risks of Irreversible Change

    The Earth’s climate and ecosystems may not only evolve through gradual change, but can also undergo rapid and potentially irreversible transformations once critical thresholds are crossed. These thresholds, known as Earth system tipping points, have become an important concept for understanding climate risks. The United Nations Secretary-General’s Scientific Advisory Board (UNSG Scientific Advisory Board) has issued a brief on this topic, emphasizing the need to strengthen climate mitigation efforts, enhance adaptation and resilience under conditions of uncertainty, and reinforce science-based decision-making.

    1527. Cutting-Edge Research Connecting the World from a Subtropical Island: Initiatives of the JIRCAS Tropical Agriculture Research Front (Ishigaki)

    June 29 is observed as the “International Day of the Tropics,” established by the United Nations.
    Located in Ishigaki City, Okinawa Prefecture, the JIRCAS Tropical Agriculture Research Front (TARF) conducts advanced research leveraging its unique climatic and geographic characteristics, functioning as a frontline hub aimed at addressing global food and environmental challenges. Specifically, in addition to contributing technologies to developing regions, the center also supports domestic efforts such as breeding rice and sugarcane varieties, conserving and managing genetic resources of tropical crops, and developing varieties of beans, vegetables, tropical fruits, and forage crops suited to the southwestern islands—thereby contributing to the promotion of regional agriculture.
    An open house at TARF is scheduled for Saturday, July 4, 2026. Those in the area are warmly encouraged to visit.

    1526. Heatwave Expands Across Europe: Copernicus Observations Highlight Elevated Land Surface Temperatures and Concerns over Ground-Level Ozone

    A severe heatwave affected Western Europe in late June 2026. Observations from the Copernicus Sentinel-3 satellites identified extensive areas with land surface temperatures exceeding 50°C across southern France and northern Spain. The European Environmental Bureau (EEB) also reported that the heatwave has contributed to elevated ground-level ozone concentrations, raising concerns about impacts on air quality and agriculture, and highlighting the importance of reducing methane emissions.
