Abstract
Abstract We compared satellite-based UAH Earth surface temperature, NOAA ENSO index, and Earth-surface CO 2 change rate in detail. These three variables were well correlated over the observed 40 years. The temperature changed approximately one year after the ENSO index changed, and the CO 2 change rate followed the temperature change by several months. CO 2 emission and absorption at the Earth’s surface responded to temperature changes. It was like Earth’s breathing. CO 2 emission due to higher temperature was related to plant respiration or decomposition processes.
