Expeditions 

 

After twenty years of expedition experience in polar, deserts, and high altitude environments, I have been an eye-witness to climate change most of my life and during many of my expeditions. Since my first trip to the Arctic in 2003, I have been reporting about our fragile ecosystems for NPR radio, as a contributing editor for National Geographic Traveler, The Huffington Post, De Volkskrant, NRC Handelsblad and many more international media organizations. I have made investigative documentary films and produced and presented television series on climate change.  I wrote two books about polar regions based on my own expeditions to the North and South Poles. I have taken more than 200 CEO’s to Svalbard  and Antarctica to see for themselves the effects of climate change and what they can do to improve  sustainable practices in their businesses and in their boardrooms. 

 

     Climate Change 

​

I have always been fascinated with climate science. In 2013 we made the TV series Tipping Points. In 6 parts we showed which ecosystems are stressed and potentially will disappear if global temperatures increase 3 tot 6 degrees Celsius. Since then I have done many science expeditions: from measuring black carbon and sulphur on Greenland’s icecap to snow measurements on the North Pole and Greenland, and methane release in Siberia, to looking at snow melt on top of Everest.  In 2017 we collaborated with NASA and ICEBRIDGE to conduct snow measurements on the North Pole to calibrate satellites and observations from the ICEBRIDGE airplane.  In 2022 we worked together with the  Dartmouth College to conduct snow measurements along the  entire 2000 km of our route along the Greenland icecap.
