IBS Center for Climate Physics

Expanding the frontiers of earth system science by conducting cutting edge research into climate dynamics and utilizing high-performance computer simulations, with the goal of improving decadal earth system forecasts and longterm projections.

We are ICCP

The IBS Center for Climate Physics (ICCP) was established in January 2017 by Axel Timmermann as the only Earth Science center within the Institute for Basic Science (IBS). ICCP expands the frontiers of Earth system science by conducting cutting edge research into climate dynamics with the goal of improving our physical understanding of natural climate variability and externally forced climate change.

ICCP scientists study coupled climate processes across the atmosphere, hydrosphere, cryosphere, biosphere, and anthroposphere and across a range of timescales ranging from months to millions of years using IBS’ high-performance supercomputer ALEPH.

Message from the Director

Over the past century increasing anthropogenic greenhouse gas emissions have become the main driver for global climate change.  In response to the corresponding increased downward infrared radiation, the earth’s surface warms, Arctic sea-ice retreats, sea level rises, climate and weather patterns shift. The absorption of anthropogenic CO2 by the ocean has affected ocean chemistry, leading to Ocean Acidification and fish-hypercapnia. To cope and adapt to the resulting environmental and ecological changes, humanity needs robust estimates of both, forced climate change and internally generated variability on global and regional scales.

Many decisions on adaption and mitigation need to be made over the next decades to limit climate damage costs and prevent long-term irreversible loss of coastlines, human livelihoods and ecosystems. Making such decisions has proven difficult, in particular in the context of the prevailing uncertainties in our physical understanding of the climate system. Some of the most persistent uncertainties are related to the overall sensitivity of our earth system to greenhouse gas forcing, cloud-feedbacks, regional patterns of future rainfall changes, the nature of carbon cycle/climate feedbacks, potential ice-sheet thresholds and the magnitude of the projected global and regional sea-level rise. Addressing these scientific challenges requires a concerted multi-disciplinary effort.

The IBS Center for Climate Physics (ICCP) provides a world-class international research environment to improve our basic understanding of climate and its variability, to develop new research frontiers in earth system science and to perform skillful decadal earth system forecasts and improved longterm projections by means of high-performance computer simulations.
