The cloud electrification process has great significance in understanding the microphysical properties and lightning discharges of thunderstorms. The in-cloud electric fields due to cloud electrification may lead to variations of orientation and alignment signatures of ice particles in the upper parts of the thunderstorms.
Wang et al. [2024] present new dual-polarization observations of electrically aligned ice crystals in a localized storm to show how the observati ..read more

Soil ecosystems play fundamental roles in sustaining food and fiber production, improving water quality and availability, sequestering carbon, and providing other societal needs. Climate warming affects the ability of soils to provide these ecosystem services, likely posing broad consequences for food security and the stability of ecosystems belowground and aboveground. To predict and manage these consequences effectively, it is crucial to understand how soil processes respond to rising temperatures.
Scientists worldwide have been conducting deep-soil-warming experiments, in which soil layers ..read more

Much of Earth’s water is hidden hundreds of meters beneath our feet, among soil particles and deep within rock pores and fractures.
Mining, oil and gas production, water wells, and other human activities involve extracting various fluids from or injecting them into the ground. Much attention has been paid to the toll these processes take on shallow groundwater and the water cycle. But less is known about how these activities affect the deep subsurface (500 meters to several kilometers deep), much of which was previously isolated for very long periods of geologic time.

Según un nuevo análisis publicado en Scientific Reports, el evento de El Niño en curso probablemente causará un rompimiento de récords en las temperaturas promedio superficiales del aire en varias partes del mundo antes de empezar a decaer este verano.
“Conocer que estas son regiones con riesgo potencial en algún momento de este año nos otorga una ventaja al momento de preparar un plan sobre cómo proteger vidas, propiedades y los recursos marinos vivos.”

A thriving coral reef is a noisy place, just like a bustling city. Fish call out to each other, crabs clatter along, and snapping shrimp fire their oversized bubble-popping pincer to stun prey.
And just like a city, the reef soundscape is punctuated by daily rush hours and lull periods. Scientists listened in on three flourishing coral reefs in Hawaii over the course of a year and uncovered a dramatic change in reef noise that unfolds as the Moon rises and sets.
“This is an important development in understanding what a healthy reef sounds like,” said Lauren Freeman, an oceanographer from the ..read more

Science is capable of pointing communities to emerging hazards that can impact their ability to operate and thrive. From long-term impacts of climate change, such as extreme weather events, to localized issues, such as sinkholes, science offers insights and prediction potential. Yet, to turn this into action that can have a lasting impact, there is a need to make a link with the people who will need to face these hazards and address them together.
The CREATE Resilience project, led by the not ..read more

Models of the global carbon cycle typically include plants, microbes, soil, and the atmosphere. But they may be leaving out an important variable: Animals, from earthworms to elephants, can have a significant, though heretofore little-studied, influence on how carbon is captured and stored in ecosystems.
A new theoretical framework from Rizzuto et al. offers a road map for including animals in carbon cycle models. Their work shows that adding both herbivores and predators to such models significantly alters both the amount and the dynamic ..read more

The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides.
Various images have now emerged of the 5 km long, 14 April 2024 Piz Scerscen rock avalanche in Switzerland. With thanks to Amt für Naturgefahren, Kanton Graubünden, Ch, these three images provide a dramatic and remarkable impression of the scale and dynamics of the landslide:-

Kalman filtering, and its derivatives, is a popular method for merging models with observations via state and parameter updates. This is done through linear mapping based on linear statics and, most prominently, the Gaussian assumption. Because processes in the Earth sciences are generally non-linear and often non-Gaussian, the methodology frequently reaches its limits.
Zhang et al. [2024] propose a methodology in which the linear map is replaced by a non-linear map based on deep learn ..read more

Permafrost underlies about 14 million square kilometers of land in and around the Arctic. The top 3 meters contain an estimated 1 trillion metric tons of carbon and 55 billion metric tons of nitrogen. Historically, the northern permafrost region has been a sink for carbon, as frozen soils inhibit microbial decomposition. But rising temperatures contribute to thawing permafrost and enhance the biogeochemical activities that exacerbate climate change by releasing greenhouse gases such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).
