If you’ve bought a plane ticket recently, you’ve probably had the option to pay a few extra dollars to offset your carbon emissions. That money might go toward planting some trees… but how many trees? Researchers at the Smithsonian Tropical Research Institute are trying to answer this very question by hand-measuring trees, weighing wood, and climbing to the top of the canopy. We tag along to see how carbon is measured, and why so much ends up in tropical forests.

Guests:

Joshua Tewksbury, director of the Smithsonian Tropical Research Institute in Panama

Helene Muller-Landau, senior scientist at the Smithsonian Tropical Research Institute researching tropical forests and ecosystems, leader of ForestGEO Global Carbon Program

David Mitre, research manager for ForestGEO at the Smithsonian Tropical Research Institute

Sergio dos Santos, project manager for the Smithsonian Tropical Research Institute’s Hydro-Meteorological and Oceanographic Monitoring Program in Panama

Luisa Fernanda Gómez Correa, intern at the Forest Carbon Lab at the Smithsonian Tropical Research Institute

Eline De Loore, graduate student at Ghent University conducting research at the Smithsonian Tropical Research Institute
