3. GLOBAL WARMING AN AVERAGE INCREASE IN THE TEMPERATURE OF THE ATMOSPHERE NEAR THE EARTH'S SURFACE AND IN THE TROPOSPHERE, WHICH CAN CONTRIBUTE TO CHANGES IN GLOBAL CLIMATE PATTERNS (EPA) CLIMATE CHANGE REFERS TO ANY SIGNIFICANT CHANGE IN MEASURES OF CLIMATE (SUCH AS TEMPERATURE, PRECIPITATION, OR WIND) LASTING FOR AN EXTENDED PERIOD - DECADES OR LONGER (EPA)
