The Climatographers’ Dr. Mark C. Trexler LinkedIn Profile and Laura H. Kosloff LinkedIn Profile have a combined total of 50 years of climate change experience. Mark was hired into the World Resources Institute in Washington, D.C. in 1988 to work on the first carbon offset project, and the larger topic of land use for mitigating climate change.

In 1991 Mark founded the first advisory firm in the U.S. focused on private sector climate risk assessment and mitigation. Trexler Climate + Energy Services (TC+ES) worked with companies, national and international agencies, and NGOs all over the United States, Canada, and Japan. TC+ES carried out the first carbon footprint for Nike, and helped Stonyfield Farm Yogurt become the first carbon-neutral company.

When TC+ES was acquired by EcoSecurities in 2007, Mark took over its Global Consulting Services Group with offices in Oxford, The Hague, and Portland, OR. The Climatographers’ Laura Kosloff became EcoSecurities’ Associate General Counsel.

In 2009 the original TC+ES team transitioned to DNVGL, a global risk management firm based in Oslo, Norway where Mark became DNVGL's Director of Climate Risk.

In 2012 Mark and Laura began to explore new ways to help get actionable climate knowledge to individuals and decision-makers. Building the Climate Web with advanced TheBrain knowledge management software has been a key focus of that effort, and today the Climate Web includes more than 100,00 climate information building blocks that can be customized in all kinds of fit-for-purpose ways.
