GeoTalk: meet Martin Archer, Space Physicist and Outreach expert!

Hi Martin. Thank you for joining me for this interview! To start, could you please tell our readers a bit about yourself and your research interests? I’m a space plasma physicist at Imperial College London, studying how the interaction between the solar wind and our magnetosphere leads to a huge amount of dynamics and waves that play a role in space weather. I’m also the Chair of EGU’s Outreach Co ...[Read More]

Image of the week – The gaze of the ice cap

We are getting used to perceiving glaciers more and more distant and disconnected from our mountains. With each passing year, it is more difficult to observe them, reach them or climb them. They are becoming an exotic element of the Alpine imagination. When our gaze rests on a mountain glacier, with its crevasses and large moraines, we are filled with the fascination of someone observing a new nat ...[Read More]

The impacts of space weather on the mid-latitude upper atmosphere

January 27, 2023

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

January 26, 2023
Tipping points in the climate system

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?

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]
