Feedbacks: permafrost, methane hydrates, and runaway warming

Air is one of the most essential elements for human life. Yet even though we depend on air, we humans are dramatically changing the atmosphere — making the air unbearably hot in some parts of the world, unbreathable in the most polluted parts of the world, and pushing the climate toward tipping points. As humans who caused this, we have to adapt to ways we’ve altered our air.
