Nature Communications, Published online: 04 May 2026; doi:10.1038/s41467-026-72672-6 This study reconstructs Earth’s temperature over the past 539 million years by integrating rock chemistry and climate models, showing that global temperatures remained within ~10–30 °C, challenging ideas of anomalously high early Paleozoic climates.
