When weather extremes meet climate change: how do scientists attribute single events to climate change?

One of the main new points of the IPCC reports AR6 with respect to the previous ones is the increased confidence that global climate change induced by anthropogenic emissions is critically affecting the dynamics of weather extremes. For summer, and specifically over Europe, the AR6 report states that we are already observing prolonged periods of extremely warm conditions with increased droughts bo ...[Read More]

Do lower mantle slabs contribute in generating the Indian Ocean geoid low?

The Indian Ocean Geoid Low is an enigmatic phenomenon in geodynamics. Many brain-storming hypotheses have been proposed in the last few decades to explain this geoid low. One popular idea argues that the high density lower mantle slabs contribute to this geoid low. Recent discoveries have shown that low-density anomalies from the African LLSVP region could have a more substantial influence on crea ...[Read More]

Imaggeo On Monday: Stands of Time

Within the heart of the Malagasy Hauts-Plateaux, the rolling grasslands are pitted by deep incisions locally referred to as lavaka (‘hole’ in Malagasy). These mass failure features provide vast quantities of terrestrial matter to local freshwater arteries, accounting for over 80% of the annual sediment load of the Betsiboka River. The collapse of the overlying laterite exposes a comparatively nutr ...[Read More]

Putting some pieces of the climate puzzle together, a chat with Jakob Zscheischler

The climate on our home planet is changing, and the effects of this change affect all of us at different levels starting from an enhancement of extreme weather events, a severe natural hazard. Climate change has several drivers, which in turn have complex interactions. Thus, it should not surprise us if climate science is a complex and interdisciplinary discipline with numerous players and great p ...[Read More]

A place called home?

Welcome to Kongsfjorden in Svalbard. The front of the glaciers terminating into the sea is an ecological hotspot, home to many marine animals, like kittiwakes, who love to hunt here. They feed on small fish and shrimp, which at marine-terminating glacier fronts are brought to the surface by upwelling glacial meltwater. Retreating glaciers lose their contact with the ocean As the planet warms these ...[Read More]
