International Panel Warns of Global Warming (Great Events: 1900-2001)
Article abstract: The second assessment report of the Intergovernmental Panel on Climate Change (IPCC) projected a rise in global mean surface temperatures. The rise would constitute the fastest rate of change since the end of the last Ice Age.
Political Concern Emerges Over Global Warming
In 1995, the Intergovernmental Panel on Climate Change (IPCC) confirmed in its second assessment report that evidence indicated that human beings were having a discernable influence on global climate. The report, Climate Change 1995: The Science of Climate Change, projected an increase of between 1.8 to 6.3 degrees Fahrenheit (1 and 3.5 degrees Celsius) in global mean surface temperatures by 2100. Such a rise in temperature would constitute the fastest rate of change since the end of the last Ice Age. The report also predicted a rise in global mean sea levels of between 5.9 and 7.5 inches (15 and 19 centimeters) by the year 2100, which would result in the flooding of many low-lying coastal areas. A rise in global temperatures would affect rainfall patterns, increasing the potential in many regions for floods, intense storms, or drought.
Natural variation has always been present in the world’s climate. According to most scientists, this natural variability has begun to be overridden by rising concentrations of greenhouse gases in Earth’s atmosphere. Although greenhouse gases such as water vapor, carbon dioxide,...
