Dr. Mark C. Trexler has specialized in climate change for the last 35 years. He founded the first climate risk consultancy in the United States in 1991, and co-authored the first business climate risk textbook in 2011. He has been a Lead Author for the Intergovernmental Panel on Climate Change, and served as Director of Climate Risk at DNV in Oslo, Norway, a 10,000 person global organization focused on risk and risk management. To improve access to actionable climate knowledge, Mark has developed a number of knowledge management solutions, and our climate books continue that effort.
