Key sections include: CLIMATE / Earth's thermostat in motion; The greenhouse effect: certain molecules trap outgoing IR.; The records reach back 800,000 years.; The hockey stick: unmistakable since 1850.; Mauna Loa, since 1958: 280 → 422 ppm.; It's us. The fingerprints are unambiguous.; Doubling CO₂ buys us roughly 3°C of warming.; Tipping points: irreversible on human timescales.; Heat. Sea level. Drought + flood. Ecosystems under stress.; The cost curves already won the technical argument..
