Destroyed Nord Stream pipelines spread methane across southern Baltic Sea, research reveals

Phys.org: Earth science - Wed, 01/15/2025 - 17:58
Methane from the destroyed Nord Stream pipelines spread over a large part of the southern Baltic Sea and remained for several months. This is according to a study by researchers from the University of Gothenburg and the Voice of the Ocean research foundation.

From drops to data: Researchers propose algorithm to improve precipitation predictions worldwide

Phys.org: Earth science - Wed, 01/15/2025 - 17:39
With the increase in climate change, global precipitation estimates have become a necessity for predicting water-related disasters like floods and droughts, as well as for managing water resources. The most accurate data that can be used for these predictions are ground rain gauge observations, but it is often challenging due to limited locations and sparse rain gauge data.

Critical ocean current has not declined in the last 60 years, AMOC study finds

Phys.org: Earth science - Wed, 01/15/2025 - 17:00
Earth, being 71% covered in water, is influenced by the ocean and its movements. In the Atlantic Ocean, a system of connected currents, called the Atlantic Meridional Overturning Circulation (AMOC), moves water throughout the world's oceans powered by a combination of winds and ocean density. It not only distributes the ocean's heat, moisture, and nutrients, but regulates the Earth's climate and weather.

Technology for oxidizing atmospheric methane won't help the climate, researchers say

Phys.org: Earth science - Wed, 01/15/2025 - 15:53
As the atmosphere continues to fill with greenhouse gases from human activities, many proposals have surfaced to "geoengineer" climate-saving solutions, that is, alter the atmosphere at a global scale to either reduce the concentrations of carbon or mute its warming effect.

Measurement of femtosecond incoherent XUV pulses using shot-noise-driven fluctuations in plasma betatron sources

Physical Review E (Plasma physics) - Wed, 01/15/2025 - 10:00

Rodriguez, C. Salgado-López, F. Stocchi, P. Tomassini, I. Vladisavlevici, M. D. Frias, M. Ferrario, and G. Gatti

The duration of incoherent XUV pulses down to the femtoseconds (fs) can be retrieved through a statistical analysis of the modulations on the observed radiation spectrum. Uncorrelated shot-noise fluctuations in the pulse temporal profile result in incoherent radiation showing a multispike spectrum w…
