8.7 Global Climate
MiStar unit 8.7
| Term | Definition |
|---|---|
| ecological footprint - | the impact of a person or community on the environment, expressed as the amount of land required to sustain their use of natural resources. |
| carbon capture and storage - | the removal of carbon from fossil-fuel combustion and storage of the carbon, usually underground |
| global warming - | An increase in the average temperature of the earth's atmosphere (especially a sustained increase that causes climatic changes) |
| mitigate - | make less severe, serious, or painful |
| biological - | relating to biology or living organisms |
| sudden - | occurring or done quickly and unexpectedly or without warning |
| gradual - | a relatively slow rate of change, or a change occurring over a relatively long time period |
| rate of change - | the speed at which a process occurs |
| net sink - | a natural or artificial reservoir that accumulates or stores carbon |
| Little Ice Age - | A century-long period of cool climate that began in the 1590s. Its ill effects on agriculture in northern Europe were notable. |
| fossil fuels - | natural carbon-based fuels (e.g., coal, oil, natural gas) formed over millions of years from the remains of living organisms |
| greenhouse gas emissions - | the output of greenhouse gases by an energy source (such as coal or oil generators), a device (such as a car) or practice (such as ranching or farming) |
| technologies - | physical devices such as electric vs gas-powered cars, electrical power generation, and practices such as methods of agriculture (irrigation, use of fertilizers) or manufacturing (plastics), reforestation programs |
| system - | A group of parts that work together as a whole |
| behaviors - | the way that people live and work, such as choices in transportation, recreation, housing, the amount of technology used, and energy usage |
| human activities - | actions (relevant to impacts on Earth's climate) which include behaviors and uses of technology; this would also include population growth. |
| solar activity - | over time scales changes in the amount of solar radiation can change global climates |
| volcanic activity - | any of the many processes (such as eruptions and lava flows) in which gas, lava, and ash are pushed out on the surface of Earth |
| atmosphere - | a mixture of gases that surrounds a planet or moon. |
| inputs - | additions to a given system |
| outputs - | losses from the system |
| solar radiation - | energy from the sun |
| mean surface temperature - | Average of near surface temperatures and near sea temperatures. |
| greenhouse effect - | warming that results when solar radiation is trapped by the atmosphere |
| thermal energy - | The total energy of motion in the particles of a substance |
| global climate change - | A broad term that refers to changes in the earth's climate mostly as a result of changes in temperature and precipitation. |
