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:

Money is power. But who's on our money - or isn’t - can be just as powerful. While Lady Liberty has graced American coins and dollars for most of our history, it wasn’t until the 1970s that a real woman appeared on a circulating American coin. But that's about to change. Congress recently authorized the creation of twenty new quarters featuring American women from history. But how do we decide whose likeness gets engraved in our national story? And who makes these decisions? We’ll follow the money to find out.
