The kinds of increases in atmospheric carbon dioxide taking place today could have a significantly larger effect on global temperatures than previously thought, according to a new study led by geologists. The team demonstrated that only a relatively small rise in atmospheric carbon dioxide was associated with a period of substantial warming in the mid- and early-Pliocene era, between 3 to 5 million years ago.
