-Air planes give off carbon dioxide - Carbon dioxide is released into the atmosphere. - Then carbon dioxide is a major contributor to the greenhouse effect and global warming. How do air planes effect global warming?

How do people effect global warming? People drive cars, trains, and air planes. We use these sources of energy much more than the sources that give off less pollution. Petroleum, one of the sources of energy, is used a lot. It is used for transportation, making electricity, and making many other things. Although this source of energy gives off a lot of pollution, it is used for 38% of the United States’ energy.

How technology influences Global warming (positively and negatively) -Creating new industries, reducing the U.S. dependence on foreign oil and lowering the need for other pollution control expenses associated with burning coal and other fossil fuels - Some negative effects of global warming are from an increase in air temperatures causes the sea level to rise causing more severe storms.
