Episode 498 - Clean air, captured carbon and paper sensors

June 28, 2022

Where is the cleanest air on the planet? How do oceans help capture carbon from forest fires? Where does all that carbon go after a forest fire? How do you find the cleanest air, by measuring microbes. The southern ocean air is not polluted by aerosols or ice forming particles. The air above the Southern Ocean is clean and crisp with not much microbes in side it. How can you turn a paper into a simple carbon dioxide sensor?
