International Coordination Office for Polar Prediction (ICO)

The International Coordination Office for Polar Prediction (ICO) supports the Polar Prediction Initiative which is an undertaking by WWRP (World Weather Research Programme) together with PCPI, the Polar Climate Predictability Initiative by WCRP (World Climate Research Programme).

The ICO is hosted by the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) having entered into a Memorandum of Understanding with the WMO

Kirstin Werner (Director)

e-mail: kirstin.werner (at) 

Kirstin has worked as a freelance journalist and in the media departments of the Alfred Wegener Institute and the Senckenberg Research Institute and Natural History Museum. During her PhD and postdocs at GEOMAR (Kiel, Germany), the Institute of Arctic and Alpine Research (Boulder, Colorado, USA), and the Byrd Polar and Climate Research Center (Columbus, Ohio, USA), she studied high-resolution sediment cores from the eastern Fram Strait in order to understand the variability of heat transfer to the Arctic Ocean and corresponding changes in the sea-ice extent during the past ca 12,000 years. In 2017, Kirstin completed her on-the-job master studies in Science Marketing at the Technical University Berlin with a study on internal and external communication in the Polar Prediction Project.
