Ancient trees may have played a key role in regulating Earth’s climate during the last ice age — by breathing less efficiently. A new study, led by a researcher at Penn State and published today (Nov. 5) in the journal Nature Geoscience, examined chemical fingerprints in subfossil wood, or preserved trees, from across North America to understand how plants responded to the low carbon dioxide (CO2) levels and cooler temperatures of the last glacial period, about 20,000 years ago.
