Under the Mediterranean sun: The thousand year tale of changing skies

Under the Mediterranean sun: The thousand year tale of changing skies

When you picture the western Mediterranean, you likely imagine sun-drenched beaches, terracotta roofs, and bright blue skies. But has it always been this sunny? A groundbreaking study published in the journal Research provides a definitive answer: it has not. By pulling back the curtain – or rather, the cloud cover – on a thousand years of climate history, scientists have developed the ...[Read More]

Do changes in Arctic climate variability severely impact migratory birds?

Do changes in Arctic climate variability severely impact migratory birds?

Changes in Arctic climate variability and extremes may have significant impacts for migratory birds, according to a study presented at EGU23 by Nomikos Skyllas, a PhD student from the University of Groningen. Many species cross continents during their seasonal migration patterns, travelling from as far as Africa and South America to northern regions such as Siberia and the Canadian Arctic. If you’ ...[Read More]

Why hydrogen – the ‘fuel of the future’ – may not be as clean as we think

Why hydrogen – the ‘fuel of the future’ – may not be as clean as we think

Around the world, the shift to hydrogen is being considered a key strategy to decarbonize the environment, with experts even calling it the fuel of the future. Hydrogen now features in all eight of the European Commission’s net zero emissions scenarios for 2050, promising to end our dependence on fossil fuels and reduce CO2 emissions across industries. So it comes as no surprise that billions of e ...[Read More]

GeoPolicy: What does the IPCC’s 6th Assessment Report tell us about the future?

GeoPolicy: What does the IPCC’s 6th Assessment Report tell us about the future?

The Intergovernmental Panel on Climate Change (IPCC) prepares and publishes extensive Assessment Reports on the scientific, technical and socio-economic knowledge on climate change, including its impacts, future risks, and likely scenarios based on the actions that humanity takes. In their sixth Assessment Report (AR6), the IPCC’s certainty and warnings were clearer than ever. This month’s GeoPoli ...[Read More]

120 years of the ‘Greenhouse Effect’

120 years of the ‘Greenhouse Effect’

120 years ago in 1901, Swedish meteorologist Nils Ekholm used the term ‘greenhouse’ to describe the heating effect that a planet’s atmosphere has on the surface temperature of the planet, the first time that this now much-used and abused metaphor was published. He wrote: “The atmosphere plays a very important part of a double character as to the temperature at the earth’s surface, of which the one ...[Read More]

Imaggeo on Mondays: Exploring the underground cryosphere

The winter season is a good time to take advantage of cold weather activities, whether that’s hitting the ski slopes or warming up by a fire, but for Renato R. Colucci, it’s also one of the best time’s to study the Earth’s underground cryosphere. Colucci, who took this featured photograph, is a researcher at Italian Institute for Marine Sciences (ISMAR) of the National Research Council (CNR) and i ...[Read More]

Imaggeo on Mondays: The changing landscape of Patagonia

Pictured here is a snapshot of an environment in transition. Today’s featured photo was taken at the foot of Monte Fitz Roy, a jagged Patagonia mountain located in Los Glaciares National Park on the border between Argentina and Chile. The Patagonia region in South America is the second biggest source of glaciers in the southern hemisphere, behind Antarctica, but the region is losing ice at a rapid ...[Read More]

How to forecast the future with climate models

How to forecast the future with climate models

Our climate is constantly changing, and with the help of simulation modelling, scientists are working hard to better understand just how these conditions will change and how it will affect society. Science journalist Conor Paul Purcell has worked on Earth System Models during his time as a PhD student and postdoctoral researcher; today he explains how scientists use these models as tools to foreca ...[Read More]
