Document Summary
If sea level rises, beach is moving landward. By extension, the environments relative to the sea level also move landward. The term temperature anomaly means a departure from a reference value or. A positive anomaly indicates that the observed temperature was warmer than the. A negative anomaly indicates that the observed temperature was cooler than the long-term average. reference value reference value. 1972- when the clean air and water act takes place and greenhouse gases dominate. Relative sea level is rising 4 mm/yr in jersey (4-5 in atlantic city/sandy hook) The suppression of global warming by sulfate aerosols. After 1970, there has been a significant drop in thickness of polar ice caps. If global average temperature rise 1 c then polar temperatures increase by 2 c. Fraction of solar energy gets released back to space. Melting ice causes more ice to start melting.
