Wake up bitches, new positive feedback loop just dropped.

Generally, the nitric oxide in lakes has not been considered a major forcing factor in air quality or climate models compared to human sources, but new research reported in Nature Geoscience focused on remote lakes on the Tibetan Plateau ... has challenged this understanding.

Within these lakes, particular bacteria thrive in the anoxic (low oxygen) environments, converting nitrogen from natural sources, agricultural runoff and sewage into ammonia, which is then converted into nitrites (nitrification) and subsequently nitrogen gas (denitrification), the latter of which creates nitric oxide as a by-product.

The formation of nitric oxide in such large quantities is problematic as it contributes to the depletion of the ozone layer, which forms a positive feedback mechanism for climate change. As the ozone layer becomes further damaged, more solar radiation can penetrate through down to Earth's surface, warming the planet. When the planet emits heat, the ever-growing greenhouse gas layer traps this heat, so rather than it escaping back out to space, it warms the planet further, creating a positive feedback loop.
