Falling Sea Level caused Volcanos to Overflow

A Team of international researches found new connections between the solid earth and the climate system

Throughout the last 800,000 years, Antarctic temperatures and atmospheric carbon dioxide concentrations showed a similar evolution. However, this was different during the transition to the last ice age: approximately 80,000 years ago, temperature declined, while the carbon dioxide content of the atmosphere remained relatively stable. An international research team led by the GEOMAR Helmholtz Centre for Ocean Research Kiel and the Alfred-Wegener-Institute Helmholtz Centre for Polar and Marine Research has now discovered that a falling sea level may have caused enhanced volcanic activity in the ocean, which can explain the anomaly. The results are published today in the journal Nature Communications.

Parallel-in-time: A comment by M. Hinze and T. Slawig

A recent article by Paul Davis in the Society of Industrial and Applied Mathematics’ SIAM news features the topic Climate Prediction, Exascale Computing and Time Parallelism.

The text reflects the increasing importance that time-parallel methods experience in high performance computing in the last years. It refers to the 2017 SIAM Conference on Computational Science and Engineering, held in Atlanta this February. There, a minisymposium was organized on the topic.
