Greenhouse Effect – Flashcards

the circulation and re-utilization of carbon atoms especially via the process of photosynthesis and respiration.

This human impact on the ecosystem includes: 1. Increased plant productivity 2. Greenhouse effect and global warming

Gases such as carbon dioxide, methane, nitrous oxide, water vapor, and ozone in the atmosphere which are involved in the greenhouse effect.

natural situation in which heat is retained in Earth's atmosphere by carbon dioxide, methane, water vapor, and other gases

1 1856-1970- stable temperatures 2. 1910-1940- increase temperatures then stable temperatures 3. 1970- rapid rise in temperature 4. 1998- hottest year 5. 2005- hottest year

A guiding principle in making decisions about the environment, cautioning to consider carefully the potential consequences of actions for not harming on possible risks of global warming with uncertainties to combat global warming

1. Glaciers melt and polar ice sheets break into icebergs to melt which will disappear completely. 2. Permafrost often melt during summer to increase the rates of decomposition of trapped organic matter to release carbon dioxide and further increase in atmospheric concentrations. 3. Species adapted to temperate conditions to spread north by alerting food chains to attract animals in higher tropic levels. 4. Pest and disease are prevalent in warmer temperatures. 5. Low-lying areas increase sea levels which will be flooded. 6. Extreme weather event are frequent.
