The upper atmosphere of Earth is constantly being impacted by the flow of charged particles being released from the sun. This flow (the solar wind) carries with it a magnetic field which distorts and reshapes that of Earth, ultimately resulting in a large amount of electromagnetic space weather energy being channelled into the polar regions. One of the most frequently observed outcomes of this pro ...[Read More]

Climate Tipping Points through the “eyes” of the Masters: a virtual art exhibition
We are running out of time in fighting the effects of climate change. With the greenhouse gasses emissions steady, the planet is reaching warming levels that could cause some large ecosystems to tip in different states. A tipping point in the climate system refers to a threshold beyond which a small change in a particular variable can cause a significant and potentially irreversible change in the ...[Read More]

Tectonics on Ice…. learning about Jupiter’s Icy Moons and the JUICE mission.
In April this year a new mission is being launched by the European Space Agency, called JUICE, which stands for the Jupiter Icy Moons Explorer. This mission aims to make detailed observations of the giant gas planet Jupiter and its three large ocean-bearing moons – Ganymede, Callisto and Europa – with a suite of remote sensing, geophysical and in situ instruments. But beyond the excitement of a ne ...[Read More]

Planetary Boundaries: A Framework against Geodynamics?
How can we determine a ‘safe operating space’ for humanity? In this week’s blog, Professor Ilan Kelman from University College London shares his thoughts about Planetary boundaries, and whether this framework will be successful for the next generations to come. The planetary boundaries framework (Rockström et al. 2009ab; Steffen et al. 2015) might be useful for communicating some of humanity’s im ...[Read More]

Geomythology. Giant’s Causeway: the mythical stone way
Ireland is famous for retaining a rich heritage of folk tales, which are thousands of years old. They tell stories about great heroes, wars and loves, fantastic creatures such as leprechauns, fairies, banshees, giants and so on. Among them, there is a Middle Earth time myth, concerning a “small” giant, named Finn McCool, who built a great stone way connecting Northern Ireland with the western Scot ...[Read More]

Image of the week – Birds in the Arctic
I am a hobby ornithologist and love watching birds. It is fun and relaxing to search the trees or fields for feathered friends. One has to be aware of their surroundings, which can make birding even meditative. Here, I will tell you more about Arctic breeding birds, their population declines and I present to you three birds of the many I saw on my very first trips to the Arctic. Arctic breeding bi ...[Read More]

Co-benefits of Nature-based Solutions: what we know and what we should know
Nature-based Solutions are on everyone’s lips in the view of their risk reduction potential but also their social, economic, and environmental side effects (so-called co-benefits). But how significant are these co-benefits? What are NBS? Nature-based Solutions (or in short NBS) are an umbrella term for ecosystem-based solutions to counteract societal challenges such as climate change, disaster, bi ...[Read More]

COVID-19 and natural hazards: a complex multi-risk scenario
COVID-19 has been a disruptive ‘tsunami’ that most countries were not prepared to handle. The pandemic has been representing a global slow-onset long-lasting disaster that has drastically challenged all emergency management systems worldwide. The pandemic slow-onset disaster has been characterized by a prolonged emergency phase with varying intensity levels, and a cyclic behavior, where the interp ...[Read More]
