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.

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.

Photosynthetic activity in Devonian Foraminifera

Benthic foraminifera play a significant role in modern reefal ecosystems mainly due to their symbiosis with photosynthetic microorganisms. Foraminifera were also components of Devonian stromatoporoid coral reefs; however, whether they could have harbored symbionts has remained unclear. We show that Devonian foraminifera may have stayed photosynthetically active, which likely had an impact on their evolutionary radiation and possibly also on the functioning of Paleozoic shallow marine ecosystems.

Congratulations to the winners of the EGU Best Blog Posts of 2021

At EGU, we like to believe that a new year is more meaningful when we pause to look back at the year gone by – just a brief glimpse to appreciate all our good work and progress! 2021 was certainly an excellent year for our blogging network at EGU. Across the EGU’s official blog, GeoLog and division blogs we had so many inspiring, thought-provoking and even entertaining posts this year. Thank you to each of you for your writing contribution! …

Living IN the Greenland ice sheet: the story of Sites I and II, Camp Century’s older, smaller siblings

Greenland, cold as it is, was appropriately front and center in the Cold War. Strategically placed between Europe and North America, the United States sought to maintain and enhance its position on the island so that American missiles and bombers were in striking range of many Soviet targets. Soviet bombers and missiles coming toward North America would streak over Greenland making early warning capabilities on the island crucial. During World War II, Americans defended Greenland under treaty with Denmark. The …

The Sassy Scientist – The Wild Card

Abasi really is in the final stretches of his PhD voyage. It’s time to pick the external member of his panel. This role is always a wild card: it could make your viva experience either a 1-hour short ego booster, or a 5-hours long living hell of questioning. He ponders: Who to choose as your external PhD committee member? Dear Abasi, Lots of variables to consider here, and potentially lots of politics to keep in mind. The standard choice is …
