When a major climate event goes almost unnoticed: the elusive 8.2 ka signal in southern France stalagmites

When a major climate event goes almost unnoticed: the elusive 8.2 ka signal in southern France stalagmites

  Around 8,200 years ago, the climate of the Northern Hemisphere experienced an abrupt disturbance. In Greenland ice cores, the signal is unmistakable: a rapid drop in temperatures, followed by a gradual return to previous conditions. This episode, which lasted about 150 years, is known as the 8.2 ka event (“ka” meaning thousand years before 1950). It is often described as the most prominent ...[Read More]

When European pollution reshaped the Asian summer monsoon

When European pollution reshaped the Asian summer monsoon

  The Asian summer monsoon is one of the most powerful climate phenomena on Earth. Each year, it brings life-giving rainfall to billions of people across South and East Asia. Its arrival determines harvests, water supply, food security, and economic stability. We often think of the monsoon as something driven locally: by the heating of the Indian subcontinent, by ocean temperatures, or by reg ...[Read More]

Inside the Baltic Sea N2O Hunt: Tracing Sources using Isotopic tools

Nitrous oxide (N2O), commonly known as laughing gas, is one of the most important greenhouse gases, and its rise in the Anthropocene significantly contributes to global warming and depletion of stratospheric ozone. The marine environment, especially coastal and marginal seas, is an important (about 25%) contributor to the global atmospheric source of N2O. Nitrous oxide is primarily produced in mar ...[Read More]

Studying societal climate impacts: why is it hard and what can we do about it

Due to the rapid rise in temperatures, it started raining on the snow and ice-covered roads, prompting the regional public transport operator to suspend all bus services. The rain also resulted in icing on the overhead lines of the main railway line coming into town. Rail traffic was also temporarily suspended. Before the adjacent highway could be salted, several tens of cars were involved in a ch ...[Read More]
