6379779009	Global climate change	Changes in the climate of Earth; an aspect of global change.	1
6379779010	Global warming	The warming of the oceans, landmasses, and atmosphere of Earth; an aspect of global climate change.	2
6379779011	Greenhouse effect	The trapping of the sun's warmth in a planet's lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface.	3
6379779012	Greenhouse warming potential	An estimate of how much a molecule of any compound can contribute to global warming over a period of 100 years relative to a molecule of CO2.	4
6379779013	Foraminifera	Tiny, marine organisms having hard shells that resist decay after death and are used as indirect measurement of greenhouse gas changes over many years.	5
6379779014	Ice coring	A sample that is typically removed from an ice sheet, most commonly from the polar ice caps of Antarctica.	6
6379779015	Climate feedbacks	A change in the climate that causes an impact that changes the climate further.	7
6379779016	Ocean Acidification	The process by which an increase in ocean CO2 causes more CO2 to be converted into carbonic acid, which lowers the pH of the water.	8
6379779017	Kyoto Protocol	An international agreement to reduce global emissions of greenhouse gases from all industrialized countries to 5.2 percent below their 1990 levels by 2012.	9
