Study predicts large future changes in climate variability by end of the 21st century
  • Press release
  • 9 December 2021

New computer model simulations identify widespread changes in climate variability under sustained anthropogenic forcing. Researchers ran multiple simulations over the period of 1850-2100, working with a “business-as-usual” scenario for strong emissions of greenhouse gases over the 21st century. The study was published today in Earth System Dynamics.

Dynamics of fortnightly water level variations along a tide-dominated estuary with negligible river discharge

Understanding tidal hydrodynamics is essential for water resources management in estuarine environments. In this study, we propose an analytical model to examine the fortnightly water level variations due to tidal motions alone in tide-dominated estuaries. Details of the analytical model show that changes in the mean depth or length of semi-arid estuaries affect the fortnightly tide amplitude, which has significant potential impacts on the estuarine ecosystem management.


A differential emissivity imaging technique for measuring hydrometeor mass and type

This paper describes a new instrument for quantifying the physical characteristics of hydrometeors such as snow and rain. The device can measure the mass, size, density and type of individual hydrometeors as well as their bulk properties. The instrument is called the Differential Emissivity Imaging Disdrometer (DEID) and is composed of a thermal camera and hotplate. The DEID measures hydrometeors at sampling frequencies up to 1 Hz with masses and effective diameters greater than 1 µg and 200 µm.


Brief communication: Effective earthquake early warning systems: appropriate messaging and public awareness roles

Earthquake early warning systems (EEWSs) can help reduce losses, but their effectiveness depends on adequate public perception and understanding of EEWSs. This study examined the performance of the EEWS in China’s Sichuan Province during the 2019 Changning earthquake. We found a big gap existed between the EEWS’s message, the public’s perception of it, and their response. The study highlights the importance of gauging EEWS alert effectiveness and public participation for long-term resiliency.

Imaggeo On Monday: Križna jama

The Križna jama Cave on the east side of the periodic Cerknica Lake in Slovenia is an underground karstic cave primarily famous as a rich site of bones of the extinct cave bear, Ursus speleus. The eight kilometer long cave is full of stalagmites and stalactites (sometimes called drip-stone decorations) and also boasts 50 underground lakes separated by sinter barriers through which crystal clear water flows. Križna jama is also one of the most biodiverse cave systems in the world, …


Geoscience communication series: navigating the light and dark sides of social media

We are thrilled to present the last episode of the EGU WEBINARS: Digitalk: online (geo)science communication series. In this episode, we will explore the light and the dark sides of using social media for science communication by a special guest, Roberto Guardo. Roberto wished to engage in science communication just after completing his PhD. “I have never liked writing scientific papers,” he said, “I like talking about science, and I thought that doing science communication would have been easy. Well, …


TS Must-read – Buck (1991): Modes of continental lithospheric extension

Buck (1991) aims at solving the intense ‘70s and ‘80s tectonic debate concerning the way extension is accommodated in continental regions (see our previous blog posts here and here). His article explores the physical conditions that can lead to the three end-member modes of lithospheric extension in continents: core complex mode, wide rift mode and narrow rift mode. The three extensional modes that Buck identifies have specific characteristics. Core complex mode is characterized by localized upper crustal extension with (i) …
