This year, the Deep Carbon Observatory will be ten years old. Geologist Isabelle Daniel, a member of the coordinating team, reviews this active international project to study the carbon cycle under the surface of the earth and discover the abundant life that lives up to 5 km below the surface of the continents.

The climate policies aimed at achieving the ambitious goal of stabilising global warming at 2°C, stipulated in the 2015 Paris Agreement, are going to cost a lot of money. To finance sustainable solutions, abundant private savings need to be redirected towards long-term investment in infrastructure, encouraged by the public authorities.

The climate is warming, but there is still time to act: this is the message being repeated by the paleoclimatologist Valérie Masson-Delmotte, prior to COP24 held in Poland from 3rd to 14th December. Her role in the IPCC makes her one of France’s leading figures in sharing knowledge about climate change.

We collectively failed to put in place sufficient economic incentives to initiate the necessary transformation of our transport. Despite some measures, this is not enough, and the point of no return is approaching.

On the climate issue, we must act very quickly by taking a step back on energy debates because the challenge covers all of our social organizations.

A numerical model quantifies the health of floating ice-shelves along the Antarctic. Several scenarios are being envisaged; the Antarctic could contribute to a rise in sea level of up to one metre by 2100.

Following archaeological digs, analysis of the lead pollution in sediments in the antique port of Naples proves that the region’s vast water supply network, based on the Augustan Aqueduct, was profoundly affected by the infamous eruption of Vesuvius that destroyed Pompeii.

In the year 79, the eruption of Vesuvius buried a large swathe of the Bay of Naples in a cloud of ash. It entirely destroyed Pompeii and Herculanum, and killed more than 3,000 people. Historians and archaeologists have long wondered about the consequences of the eruption on the water supply of the bay, a popular holiday destination for the Roman aristocracy.

Towns on the Bay of Naples were supplied with fresh water by the Aqua Augusta, a network of galleries, canals, r...
