Spain's giant hail event worsened by marine heat waves, study finds
Hail is a semi-frequent visitor to winter, and occasionally summer, seasons across the globe and tends to pass by in a short but sharp downpour that can often be overlooked. However, sometimes these meteorological phenomena are hard to ignore. This was the case on 30 August 2022, when Gerona, north-eastern Spain, experienced a severe event in which individual hailstones reached a massive 12cm—the largest ever documented in the country. This led to serious damage to buildings, cars and agricultural areas, as well as 67 injuries and one fatality. |

A new estimate of US soil organic carbon to improve Earth system models
Soil contains about twice as much carbon as the atmosphere and plants combined. It is a major carbon sink, capable of absorbing more carbon dioxide from the atmosphere than it releases. Management of soil carbon is key in efforts to mitigate climate change, in addition to being vital to soil health and agricultural productivity. |

Sediment discovery unlocks Australia's hidden net-zero resource potential
A new method of measuring sediment thickness across Australia's interior offers a cost-effective and straightforward solution for estimating seismic hazard and resource potential while reducing carbon footprint, according to the largest study of its kind from The Australian National University (ANU), published in the Geophysical Journal International. |

Australia on track for unprecedented decades-long megadroughts, finds modeling study
Australia could soon see megadroughts that last for more than 20 years, according to new modeling from The Australian National University (ANU) and the ARC Center of Excellence for Climate Extremes. |

Why we need to rethink what we know about dust
You may think of dust as an annoyance to be vacuumed and disposed of, but actually, on a grander scale, it is far more important than most people realize. Globally, dust plays a critical role in regulating our climate, radiation balance, nutrient cycles, soil formation, air quality and even human health. |

Ocean forests: How 'floating' mangroves could provide a broad range of ecological and social benefits
The 2022 report "The State of the World's Mangroves" estimates that since 1996, 5,245 square kilometers of mangroves have been lost due to human activities such as agriculture, logging, tourism development, coastal aquaculture and climate change, and that only 147,000 km2 remain. It is a well-known fact that mangrove forests are among the most productive marine ecosystems in the world, located at the very start of the marine food web (the productivity of biomass by plants is called primary productivity). They serve as a natural nursery for fish and also provide protection against coastal erosion. |

South Australian coastal dunes are on the march
Coastal transgressive dunefields are on the march in South Australia—retreating inland from an angry ocean at an alarming rate. Yet while this occurs in plain sight, communities are largely oblivious to long-term coastal changes, and Flinders University's Professor Patrick Hesp, strategic professor of coastal studies at Flinders University's College of Science and Engineering, is concerned this is all happening in a geological blink of the eye. |

From data to decisions: AI and IoT for earthquake prediction
The study of earthquakes remains a main interest worldwide as it is one of the least predictable natural disasters. In a new review published in Artificial Intelligence in Geosciences, a team of researchers from France and Turkey explored the role of conventional tools like seismometers and GPS in understanding earthquakes and their aftermath. |

Scientists' urgent call: End destruction and forge a just, sustainable future
An international team of scientists has published a study in PNAS Nexus, emphasizing the urgent need to align political will, economic resources, and societal values to ensure a more sustainable and equitable world. Led by University of Hawai'i at Mānoa researchers, the 18 authors combine their expertise in Earth and ocean sciences, politics, law, public health, renewable energy, geography, communications, and ethnic studies to assess causes, impacts, and solutions to a multitude of worldwide crises. |
