Dr. Mark C. Trexler

Course Instructor

Dr. Mark Trexler started working on climate change in 1988 with the World Resources Institute in Washington, D.C., founded the first climate risk consultancy in the United States in 1991, was a Lead Author and Chapter Editor for the Intergovernmental Panel on Climate Change (IPCC), co-authored the first business climate risk textbook, and was Director of Climate Risk for the global risk firm of DNV. He started building the Climate Web in 2010 as a knowledge management solution for understanding and tackling the "wicked problem" of climate change.


From my perspective, Trexler’s work, as supplemented by Climate Web resources, offers the most balanced and comprehensive basis for climate risk assessment and risk management available!

Dr. George Backus, Sandia National Labs

Mark's deep knowledge of climate change risk and adaptation issues is simply unsurpassed. His comprehensive domain knowledge and ability to communicate truly complex issues to a sometimes reluctant audience is extremely impressive.

Dr. Eirik Nyhus, DNV Environment Manager

The Climate Web is like having 100 leading experts in climate science, risk, risk management, and corporate strategy collaborating with you at the decision-making table. 

Rick Love, UTC Environment Director

A superb course. Dr. Trexler‘s comprehensive knowledge allows him to simplify a muddy discussion. He’s able to take a big subject and boil it down to the essential parts. This is a huge plus for viewers. I especially liked the non-polemic tone. This is clearly an educational course, not a partisan viewpoint. Well done!

Jeffrey Atkin, CEO World Forest Group

I really appreciated the Carbon Offsets Course. It’s amazing how hard it is to find good resources and thinking like this on carbon offsets. None of my typical channels/NGOs surface things like this. Highly recommend.

Max Scher, Senior Mgr Sustainability, Salesforce

I recommend this course. It's packed full of valuable information, which covers key concepts — permanence, additionality, and leakage — and raises a couple of critical questions such as the current status of carbon offsets and where carbon offset markets are headed. Go check it out, you'll love it.
