Scientists studying oxygen isotopes in fossilized dinosaur teeth have reconstructed the Earth’s climate from 150 million years ago. Findings reveal that during the Late Jurassic, atmospheric carbon dioxide levels were four times higher than preindustrial times. The oxygen isotope composition in tooth enamel confirmed significantly hotter global temperatures during that era.
