  • Convection-resolving simulation over Europe

    When the hybrid supercomputer “Piz Daint” came online in 2014, one of the first science projects that it ran was a convection-resolving simulation of the climate over Europe between 1999 and 2008. Now the researchers have...

  • Can cirrus cloud seeding help to “save” the climate?

    Researchers at ETH Zurich used ‘Piz Daint’ to simulate how cirrus cloud seeding, a novel geoengineering method, might impact the Earth’s radiation balance. Their findings are sobering.

  • Where the Earth is humming and whistling

    The Earth is constantly in motion, like a vibrating bell. Natural forces are the origin of these vibrations, which are registered by seismometers as a kind of humming and whistling. Although there is still a debate about the...

  • Cold and snow came from the south

    As simulations conducted by climate researchers from the University of Bern and the Oeschger Centre reveal, the precipitation during the last ice age came from the Mediterranean. Therefore, the glaciers in the Alps presumably...

  • Summer storms and heavy rainfall in the future climate

    Hail, thunderstorms and heavy rainfall. These extreme events are supposedly on the increase in the course of global warming. High-resolution simulations conducted by ETH Zurich researchers on CSCS’s supercomputers now add more...

  • Trend signals from the oceans

    Scientists at the University of Bern have shown in a new study that the imprint of carbon dioxide emissions caused by humans can be rapidly detected in the oceans. For the researchers, the short timescales represent a further...

  • Zooming into the Earth's interior with a supercomputer

    Scientists have set themselves the goal of using simulations to map the Earth’s interior in so much detail that you can zoom in at any point. They have already managed to do so for small regions. Now they are looking to take one...
