GeoTalk: meet Shradha Menon, researcher of island stability under climate change and Early Career Scientist Representative!

Simon Clark October 11, 2024

Hello Shradha – welcome to GeoTalk. Before we kick off, could you introduce yourself to our readers? Hi Simon and thank you for inviting me to the GeoTalks Series. I am Shradha Menon and I I am from Kerala, a state in the southern part of India. I am a geologist at heart and my side quests include archaeology as well. I am currently pursuing a PhD in carbonate sedimentology at the Indian Ins ...[Read More]

Cultural heritage: an overlooked yet critical aspect of climate change

Simon Clark August 29, 2024

In June 2024, climate activists sprayed Stonehenge orange, demanding urgent action from the British government to phase out fossil fuel. This divisive act evoked a destructive yet often overlooked impact of climate change: the damage and destruction of cultural heritage. We are losing our cultural heritage at an unprecedented speed and scale to climate change, according to a 2022 report by the Eur ...[Read More]

GeoTalk: meet Gino de Gelder, researcher of the link between tectonics, sea-level rise & coral reefs!

Simon Clark January 12, 2024

Hello Gino! Welcome to GeoTalk. Could you tell our readers a little bit about yourself and your background? Sure thing! My background is mostly in tectonics, geomorphology and the evolution of (active) fault systems, which I developed during my studies at Utrecht University and my PhD at the IPGP (Paris). Initially I focused on the way that coastlines record either uplift or subsidence in response ...[Read More]

GeoTalk: meet Andreas Kvas, researcher of Earth’s gravity affected by climate change!

Simon Clark November 17, 2023

Hello Andreas. Welcome to GeoTalk! You’re a specialist in Geodesy, and your research surveys the Earth’s spatial and gravitational properties as they relate to climate change. Could you tell us more about how Geodesy can help us understand climate change? Geodesy studies Earth’s geometric shape, orientation in space, and gravity field. Each of these components changes in time and is af ...[Read More]

A chunk of ice the size of Amsterdam: how the calving of Greenland’s glaciers has changed since the 2010 Petermann Glacier event

Alka Tripathy-Lang August 4, 2023

Thirteen years ago, a roughly 251 km2 chunk of ice (or 97 miles2) broke off Greenland’s Petermann Glacier. This Amsterdam-sized piece of ice was the largest to calve in the Arctic since 1962. The massive iceberg traversed the Nares Strait, which lies between Canada’s Ellesmere Island and Greenland, and into the northern part of Baffin Bay—the northwestern-most arm of the Atlantic Ocean, before eve ...[Read More]

GeoTalk: To understand how ice sheets flow, look at the bedrock below

Olivia Trani August 17, 2018

Geotalk is a regular feature highlighting early career researchers and their work. In this interview we speak to Mathieu Morlighem, an associate professor of Earth System Science at the University of California, Irvine who uses models to better understand ongoing changes in the Cryosphere. At the General Assembly he was the recipient of a 2018 Arne Richter Award for Outstanding Early Career Scient ...[Read More]

Imaggeo on Mondays: Ice forming on Chesapeake Bay

Laura Roberts-Artal October 23, 2017

Sandwiched between the U.S states of Mayland, Delaware, Pennsylvania, New York State, the District of Columbia and Virginia, lies Chesapeake Bay, the largest estuary in North America. It is of huge ecological importance: “the bay, its rivers, wetlands and forests provide homes, food and protection for countless animals and plants”, says the Chesapeake Bay Program. Up to 150 major rivers and stream ...[Read More]

Geosciences Column: How El Niño triggered Indonesia corals die-off

Laura Roberts-Artal March 3, 2017

In the glistening waters of Indonesia, shallow corals – the rain forests of the sea – teem with life. Or at least they did once. Towards the end of 2015 the corals started to die, leaving a bleak landscape behind. An international team of researchers investigated the causes of the die-off. Their findings, published recently in the EGU’s open access journal, Biogeosciences, are rather ...[Read More]

IPCC report ‘unprecedented changes’ in climate, urging policymakers to take action

Sara Mynott October 4, 2013

“Human influence on the climate system is clear” was the key message from the report on the physical science of climate change from the Intergovernmental Panel on Climate Change (IPCC). “We have come a long way since the first IPCC report was published in 1990,” a statement reiterated throughout the press conference for the release of the report. The IPCC were keen to register the significance of ...[Read More]

Sussing out sea level rise

Sara Mynott February 28, 2013

Ocean thermal expansion, that is, the increase in water volume due to temperature alone, is relatively well understood – as is the retreat of both mountain glaciers and ice caps. While most models simulate these effectively, there is little understanding of how both the Greenland and Antarctic ice sheets will respond to climate change. This is because the full extent of ice-ocean interactions is n ...[Read More]
