When carbon emissions break nature: icebergs and their feedback to climate change
This image distributed by the European Space Agency (ESA) on May 20, 2021 shows a view of the A-76 iceberg off the Ronne sea ice in the Weddell Sea, Antarctica. It was captured by the Copernicus Sentinel-1 mission. Credits: ESA.

The largest iceberg in the world, named A-76, about 170 km long and 25 km wide, is drifting away from the Ronne pack ice in Antarctica. A76, originally spotted by the British Antarctic Survey (BAS), a British polar research organization with a base nearby, will wander and melt in the Weddell Sea, according to a statement released Wednesday, May 20, by the European Space Agency. Several studies are ...[Read More]

Four reasons for still observing cold spells despite the undeniable global climate change
Stravinsky fountain, near the Centre Pompidou (Paris) frozen by the cold wave of 2021.

The winter of 2020-2021 has been characterized by various cold waves affecting – at different times – Western and Eastern Europe and North America.  The most striking pictures show Madrid covered by up to 40 cm of fresh snow, frozen Thames near London and Canal St Martin in Paris, heavy snow in Amsterdam and even on the Eolian Islands, just offshore Sicily. At first this seems contradi ...[Read More]

NP Campfire: “Perspectives on Climate Science: from historical developments to research frontiers”

Recently, the European Geosciences Union (EGU) started to support a new type of event called ‘Campfires’ that will give the Divisions the freedom to run online interactive events in a way that suits their needs. This allows the EGU Divisions to encourage interactions in their research communities through virtual informal meetings. In this framework, and thanks to a group of young and established s ...[Read More]
