Exxon Research and Engineering Company

Exxon was so serious about its Bell Labs of Energy dream, it even poached Bell Labs Executive Research Director Ed David to run its research arm. Garvey and Shaw started out using equipment from the La Monde Dordi Lab at Columbia University. The device took about 10 readings per hour of the CO2 in both the air and the ocean as the tanker sailed the Atlantic and crossed the equator. What's very clear in speaking with Garvey and various other scientists is that any uncertainty that existed at the time was not over whether climate change was happening or whether humans were contributing to it.
