Last night's episode of Fox's Cosmos series didn't seem political or controversial, at least on the surface. Rather, it introduced us to the world on the molecular and atomic scale, at one point venturing inside of a dewdrop (packed with extremely cool tiny organisms like tardigrades) and, later, inside of a plant cell. It was kind of reminiscent of what you learned in your ninth grade bio class -- albeit much less sleep inducing.
Yet fresh from ticking off creationists, this time around host Neil deGrasse Tyson managed to work in the science of climate change.
Plants, after all, are the reigning global masters of clean energy. They use 100-percent solar power: The chloroplast, the so-called "powerhouse" of a plant cell, is a "3-billion-year-old solar energy collector" and a "submicroscopic solar battery," as Tyson put it. Basically, chloroplasts use sunlight, carbon dioxide, and water to store energy in sugars, and give off oxygen as a byproduct. And without this fundamental green energy technology, life on this planet as we know it wouldn't exist.
That's where Tyson brought up climate change. Here's how he put it:
