Earth’s temperature fluctuations over the past 485 million years have been more extreme than previously believed. Recent reconstructions using computer simulations show a wider range of temperatures, from 14° C to 26° C. Surprisingly, these temperature changes closely correlated with shifts in atmospheric carbon dioxide levels, overshadowing the impact of solar radiation on Earth’s climate. Scientists at the Smithsonian National Museum of Natural History in Washington, D.C., uncovered this intriguing connection while researching for the museum’s new “Deep Time” fossil hall. Paleoclimatologist Emily Judd was particularly intrigued by this puzzle.
