The Climatographers started working on climate change more than 30 years ago when Dr. Mark Trexler joined the World Resources Institute in Washington, D.C. in 1988. His work there focused on the role of forestry and land use change in mitigating climate change. He published several of the first major studies on the topic, and worked extensively on these topics as a Lead Author and Chapter Editor for the Intergovernmental Panel on Climate Change (the IPCC). He was a member of the IPCC when it received the Nobel Peace Prize.

Mark founded Trexler Climate & Energy Services (TC+ES) in 1991, working with national and international agencies, NGOs, and companies around the world for the next 15 years. TC+ES carried out the first carbon footprints for The Nature Conservancy, Nike, and the electric utility PacifiCorp, and the first Scope 3 footprint for Stonyfield Farm Yogurt. TC+ES also worked with Stonyfield Yogurt to make it the first carbon-neutral company in 1996. TC+ES did many of the first carbon offset projects, while also publishing extensively on the problems that have characterized the environmental integrity of carbon offset markets.

Most recently Mark served as Director of Climate Risk for Det Norske Veritas, a global risk management firm based in Oslo, Norway. Today, in addition to his work with the Climatographers, Mark also teaches Climate Change Mitigation at George Washington University in Washington, D.C.

Laura Kosloff has had a career as an environmental attorney, including with the Environmental Law Institute in Washington, D.C., and as an environmental litigator for the U.S. Department of Justice. She joined TC+ES as General Counsel in 1993, working on a wide variety of climate-related contractual and legal matters.

Based on their decades of work on climate change, and the insight of the famous Princeton scientist and sociobiologist E.O. Wilson, Mark and Laura started building the Climate Web in 2010 with the goal of exploring how knowledge management tools could be used to improve climate change decision-making through better access to actionable climate change knowledge. The Climate Web effectively crowdsources the insights and expertise of thousands of climate experts and thought leaders, and covers almost every variable relevant to climate change decision-making.
