SUMMIT COUNTY — Carbon may not be the only significant factor in long-term global climate cycles, according to University of Toronto scientists, who say that pulses of gypsum may have changed the oceans chemistry enough to affect atmospheric heat retention.Those changes may be a key driver of Earth’s “icehouse climate” cooling trend of the past 45 million years.“Seawater chemistry is characterized by long phases of stability, which are interrupted by short intervals of rapid change,” said geoscientist Ulrich Wortmann, lead author of a paper reporting the results and published this week in the journal Science.
