  "textContent": "Carbon dioxide levels in this dataset vary between 170 parts per million (ppm) and 280 ppm. If the level had fallen below 150 ppm, photosynthesis would have stopped and an almost certain mass extinction of land-based life would have occurred. Hatton observes that in 556 centuries of the 800,000-year Vostok database, CO2 was below 190 ppm.",
