CO₂ and Us: What’s Settled, What’s Debated, and What FYT Will Do About It
Carbon dioxide (CO₂) is essential for life: plants use it to photosynthesize; oceans exchange it with the air; rocks slowly lock it away. But CO₂ is also a greenhouse gas that traps heat near Earth’s surface. In moderation, that greenhouse effect makes the planet habitable; in excess, it drives warming.
