A touch of space weather! An EGU funded outreach project for blind and visually impaired students

Lenka Zychova January 4, 2023

This image shows four tactile images created to share space weather phenomena with blind and visually impaired learners. The image shows a representation of the magnetosphere (a small blue ball with black concentric circles surrounded by dots to the left and right, the ones on the left are smaller), aurora formation (a small blue ball with black concentric circles to the left and right with dots on the circles) and radiation belts ( a small blue ball with a yellow and brown pair of rings extended evenly to the left and the right). All the images are on a white background.

We can all probably agree that the Northern Lights are one of the world’s most spectacular natural displays. But how do we share this beauty with children who are blind? How do we explain the processes behind the aurora creation to the visually impaired when all the illustrations of Earth’s magnetosphere are in 2D? The Northern Lights are just one of the consequences of ‘space weather’. Space weat ...[Read More]

The Great Cold Debate: Is Climate Change to Blame for Extreme Cold Spells?

Davide Faranda December 27, 2022

In December 2022, the United States experienced a severe cold spell, with record-low temperatures being recorded in many parts of the country. While it is natural for cold spells to occur, the question has arisen as to whether climate change is playing a role in the intensity and frequency of these events. There is ongoing debate among scientists about the relationship between climate change and ...[Read More]

Scientific disobedience: where are our catchment boundaries?

Sylvain Kuppel December 16, 2022

On the night preceding Halloween, somewhere in the main police station of Munich, 15 people appeared one by one before a judge of the local court who notified them their deprivation of liberty, deemed as “indispensable in order to prevent the imminent commission/continuation of a criminal/orderly offence of considerable importance for the general public”. For most of them this preventive custody w ...[Read More]

For Dummies: How Arctic sea ice and the AMOC interact

David Docquier December 9, 2022

In this post, I will talk about two famous characters of the climate system; I will define them and see how they have changed in the current context of climate change. I will also show you how these two characters interact, one influencing the other, and vice versa. Finally, let’s see how the future looks like for them and the consequences for the global climate. I hope you will enjoy this story. ...[Read More]

Nitrogen dioxide disparities in the time of COVID-19: How satellite data can facilitate environmental justice studies during this natural experiment and beyond

Gaige Kerr November 9, 2022

Around the world, the most vulnerable, marginalized, and racialized are disproportionately impacted by a variety of environmental stressors such as extreme heat, health-harming air pollution, and the growing impacts of climate change. In the United States, research has uncovered how Black and Brown communities and those with lower socioeconomic status are exposed to higher concentrations of many a ...[Read More]

When race and natural hazards intersect: three geoscientists share their experiences

Gillian D'Souza October 26, 2022

Around the world, the month of October is observed as Black History Month and includes the International Day for Disaster Reduction. While both these observances are significant in their own right, it gave EGU the opportunity to hear from geoscientists of Black, Indigenous, and People of Colour (BIPOC) communities about the many ways that race and natural hazards are linked: does one affect the ot ...[Read More]

Let’s begin the recovery before the disaster

Soheil Mohammadi October 24, 2022

Every natural event that causes damage to the built environment must be followed by recovery; however, this phase of disaster risk management has received less attention from academics than the others [1]. In all its aspects, disaster recovery has remained a contentious topic, with experts debating its definition, approaches, objectives, activities, and even when it should begin and finish [2–4]. ...[Read More]
