The last few weeks have been filled with devastating news – harrowing stories about the police killing black people. Racial inequalities and discrimination go far beyond current events. In science in general, and in the geosciences in particular, little progress has been made regarding diversity over the past few decades. This is both the result of deep-seated institutional racism (sometimes refe ...[Read More]

Imaggeo On Mondays: “The most valuable thing we extract from the ocean is our existence” Dr Sylvia Earle
Marine plastic is just one of the many challenges facing the future of our oceans. For many years researchers have been attempting to understand this problem, but it can be surprising to learn how many things are still unknown, even in oceans we may think of as being familiar. The Mediterranean Sea is one such place, where this photograph was taken by David Jones just off the coast of Malta.   ...[Read More]

NH Medallists episode III – Claire Horwell and her interdisciplinary work on volcanic emission hazards for human health
In today’s interview, we talk with Prof. Claire J. Horwell. Claire has been awarded the 2020 Plinius Medal for her outstanding interdisciplinary research on the respiratory health implications of inhaling volcanic emissions, and other particulates. my research focuses on protecting communities from exposures to potentially harmful airborne particulates Hi Claire, can you please briefly introduce ...[Read More]

Is planting trees a feasible large-scale solution to mitigate climate change?
In the last few years it has become a common practice to compensate carbon dioxide (CO2) emissions by planting trees. This idea is simple and rooted on a very basic principle: trees get the energy of sunlight, and by photosynthesis they take water from the ground and CO2 from the air, releasing oxygen in the atmosphere. The CO2 is then stored in trees and surrounding soil. Tree planting efforts ar ...[Read More]

Public Engagement Grant Winner – Crabby’s Reef
Ocean acidification could be described as climate change’s evil twin, not that it needs one. The world’s oceans are partly absorbing the carbon dioxide we are pumping into the planet’s atmosphere, which then reacts with seawater and forms carbonic acid. This process decreases the pH of the oceans, making them more acidic. If you are a crab resident of the ocean, this is not good news. Norma ...[Read More]

Women of Cryo I: Dr Emma Smith
Women make up 50.8% of the world’s population, yet fewer than 30% of the world’s researchers are women. Of this percentage, women of colour comprise around 5%, with less than 1% represented in geoscience faculty positions. Women are published less, paid less, and do not progress as far in their careers as men. Even within our EGU community, women account for only one third of all members, an ...[Read More]

The Sassy Scientist – Meddle With Medals
Befuddled by the yearly returning celebration of science during the Nobel award ceremonies, and heavy-heartedly noticing the absence of Earth sciences at this ball time after time, Pippi pulled herself out of her rationally induced depression and asked: Shouldn’t there be a Nobel prize in Earth sciences? Dear Pippi, Well, isn’t that a particular poignant question? Earth sciences simply being denie ...[Read More]

Plant carbon allocation, soil nutrient availability and the mycorrhizal business
The soil market: plants spend some of their carbon on buying nutrients from mycorrhizae Similar to the way that we take up carbon (C) through the food we eat, plants absorb C in the form of CO2 from the atmosphere through photosynthesis, and use it to build sugars (Fig. 1). After having a good snack, our body decides where to send the C it has just gained: should I use it to grow muscles (or fat), ...[Read More]

Hydrological tipping points: Can we tip the bucket?
We live in a time of unprecedented pressure on water resources. The combination of drivers, such as human water use and land use, climate change by greenhouse gases and the human modification of other components of the Earth system coupled to the water cycle, may be pushing water resources beyond levels of sustainability at all spatial scales (Gleeson et al., 2020; Zipper et al., 2020). A particul ...[Read More]
