Bacteria and other microbes suck up and blast out vast amounts of greenhouse gases. Over at Yale Environment 360, I take a look at how they will behave in a world warming up as we inject carbon dioxide into the atmosphere. Will they draw down some of the extra CO2, or will the heat spur them to spew out more? Or both? The answer isn’t clear yet, but it’s important. After all, it’s a microbial planet, and we just live on it. Check it out.
