I am a Geo-ecologist (MSc) and specialized in analyses of climate extremes in climate models (PhD, IMPRS ESM, Hamburg). 

I study various factors that can drive changes in climate extremes, such as climate variability and anthropogenic factors (e.g., greenhouse gases and air pollution). I strive for interdisciplinary approaches and better integration of natural and social sciences. Particularly, I am interested in relating physical aspects of climate extremes to socio-economic impacts and questions related to adaptation and decision making.

Projects

  • CiXPAG - Interaction of Climate Extremes, Air Pollution and Agro-ecosystems Future food production, and consequently food security, is very sensitive to both climate change and air pollution. So far, little is known about how climate extremes and ozone pollution interact to affect agriculture or about the relative effectiveness of climate change adaptation and ozone regulation measures for various crops and regions.
  • NAPEX Precipitation is arguably the most direct link between the climate and human society. We depend upon existing precipitation patterns for fresh water and food production, and global infrastructure is designed to withstand current precipitation extremes.
  • HYPRE - HYdropower and PREcipitation trends Investigating historical and future precipitation trends in regions important for hydropower production
  • Translating Weather Extremes into the Future – a case for Norway TWEX-Future.no will be taking a novel “Tales of future weather” approach. This approach suggests that scenarios tailored to a specific region and stakeholder in combination with numerical weather prediction models will offer a more realistic picture of what future weather might look like, hence facilitating adaptation planning and implementation.
  • ClimateXL Weather and climate extremes are likely to be one of the largest societal challenges associated with climate change in this century. Under climate change, these extreme events will intensify and become more frequent, and consequently the risk of severe and costly damage for humans and infrastructure will increase.
  • SUPER - SUb-daily Precipitation Extremes in highly-populated Regions The main objective of SUPER is to quantify the influence of anthropogenic activity on sub-daily extreme precipitation in highly populated regions

  • Climate services at Our Common Future CICERO researchers Jana Sillmann and Karianne de Bruin are co convening a session on climate services during Our Common Future in Paris. 
  • Heat waves in Africa every year from 2040? Climate analysis shows that periods of unusually hot weather are on the rise for one of the most vulnerable continents to climate change, even if the increase in global average temperature remains at a modest level.
  • Making sense of future climate Did you believe only science fiction deal with futuretypes? Well, think again. A bunch of real scientists is carving out possible futuristic climate scenarios right now, and if you live in Norway, they might be zooming in on your hometown.
  • Local fires reduce rainfall in dry season in southern Africa Emissions of particles, in particular soot, from local fires in southern Africa have increased due to human activities. Along with increasing global CO2 levels, these particles have led to a reduction in precipitation during the dry season in the region. The findings, published in a new Nature Communications paper by CICERO and the University of Leeds, illustrate that reducing or cleaning local fires may help to counteract reduced rainfall.
