DESCRIPTION

Global Warming and Polar Ice Heat-trapping gases (C0 2, CH 4, etc.) Heat-trapping gases (C0 2, CH 4, etc.) 1.Heat-trapping gases produced mainly by human activity collect in the atmosphere (CO 2 [carbon dioxide], CH 4 [methane], etc.) 2.The sun heats the surface of the earth. 3.More heat enters the atmosphere than escapes because some of it is absorbed and some of it is reflected back by the blanket of heat- trapping gases. 4.Heat melts ice, revealing tundra and creating water. 5.Tundra releases CH 4, a more effective heat-trapping gas than CO 2. 6.Water reflects less heat than ice does because it’s darker than ice.

Important TermsImportant Terms Technology is often defined as the application

of scientific principles to the improvement of human life.

The term normal accident recognizes that the very complexity of modern technologies ensures they will inevitably fail, though in unpredictable ways.

A risk society is a society in which technology distributes danger and advantage among all social groups. However, some categories are more exposed than others.

Global Warming and Polar IceGlobal Warming and Polar Ice

Heat-trapping gases (C02, CH4, etc.)

1. Heat-trapping gases produced mainly by human activity collect in the atmosphere (CO2 [carbon dioxide], CH4 [methane], etc.)

2. The sun heats the surface of the earth.3. More heat enters the atmosphere than escapes because

some of it is absorbed and some of it is reflected back by the blanket of heat-trapping gases.

4. Heat melts ice, revealing tundra and creating water.5. Tundra releases CH4, a more effective heat-trapping gas

than CO2.6. Water reflects less heat than ice does because it’s darker

than ice.

Genetic pollution refers to the health and ecological dangers that may result from artificially splicing genes together.

Recombinant DNA is a technique that involves artificially joining bits of DNA from a donor to the DNA of a host.

Environmental issues become Environmental issues become social problems when…social problems when…

1. Policy-oriented scientists, the environmental movement, the mass media, and respected organizations must discover and promote the issues.

2. People must connect real-life events to the information learned from these groups.

3. Scientists, industrial interests, and politicians who dispute the existence of environmental threats must fail to convince the public that the threat is illusory and human intervention is unnecessary.
