10 Questions
What does global warming mean?
Global warming means an increase in the average temperature of the earth's atmosphere near its surface - either from natural or human causes - that may result in a change in global climate patterns.
What is the greenhouse effect?
The greenhouse effect is the normal trapping of the earth's heat in the lower atmosphere, due to the conversion of light into heat as it strikes the earth's surface.
What are CO2 and CFCs?
CO2 (carbon dioxide) and CFCs (chlorofluorocarbons) are gases that trap infrared radiation in the atmosphere, contributing to the greenhouse effect.
What are the two main greenhouse gases mentioned in the text?
carbon dioxide and methane
What are the primary sources of increased greenhouse gas concentrations?
burning of fossil fuels and decomposition of trash
Why are fossil fuels the most popular for energy production and transportation?
they are the least expensive to use currently
What is one of the byproducts of trash decomposition?
methane gas
What is the greenhouse effect and how does it work?
The greenhouse effect is the trapping of heat in the Earth's atmosphere by greenhouse gases. Visible light passes through the atmosphere and is converted to heat, which is then trapped and reflected back to the Earth by gases in the atmosphere.
What are greenhouse gases and what are their sources?
Greenhouse gases include carbon dioxide (CO2), methane (CH4), water vapor, nitrous oxide (N20), and CFCs. They are emitted from natural sources such as volcanoes and animal waste, as well as human activities like the combustion of fossil fuels and increased livestock production.
What is the current concentration of carbon dioxide in the atmosphere and how has it changed over time?
The current concentration of carbon dioxide in the atmosphere is 391 parts per million (ppm). It has increased from 315 ppm in 1960 and was historically measured to be between 200 and 280 ppm.
