Document Summary
Increased during 20th century warmest during the 1990s, most recent increase 2005. Daily measurements demonstrate earth"s average surface temperature. Will lead to global warming in the 21st century. Ipcc if human produced air pollutants continue to change atmosphere we will experience a. 5. 8c degree change by 2100 with regional differences. Cause the greenhouse effect: carbon dioxide, methane, surface ozone, nitrous oxidde, chlorofluorocarbons. Greenhouse effect atmosphere retains heat, natural trapping of the ir (heat_ in the atmosphere via the gases: warms earth"s surface. May cause sea level rise during 21st century (20 degrees by 2100: thawing of glaciers and polar ice caps and thermal expansion from warmer waters, more frequent hurricanes causing coastal erosion. Precipitation patterns may change: more frequent droughts in some areas. Reduction in streams as a result of reduced snow caps melting: more frequent flooding (snow and rain) in other areas.
