I am a physicist by training and work with climate analysis on a Norwegian project called RegClim, and have affiliations with the Norwegian Meteorological Institute (met.no) and the Oslo Climate Group (OCG). I have a D.Phil in physics from Atmospheric, Oceanic & Planetary Physics at Oxford University in the United Kingdom. Recent work involve a good deal of statistics (empirical-statistical downscaling, trend analysis, model validation, extremes and record values), but I have also had some experience with electronics, cloud micro-physics, ocean dynamics/air-sea processes and seasonal forecasting. In addition, I wrote the book 'Solar Activity and Earth's Climate' (2002), published by Praxis-Springer, and I sit on the council of the European Meteorological Society, representing the Nordic countries and the Norwegian Meteorology Society. 

In my work, I often get questions from media and lay persons about climate change. I believe it is necessary to approach these questions with identifying what we really don't know and what we are more sure about. I believe that some of Karl Popper ideas about falsification can be useful.
