APES Ch 19 Flashcards

13476995914	global climate change	changes in the average weather that occurs in an area over a period of years of decades	0
13476995915	global warming	the warming of the oceans, land masses, and atmosphere of the earth	1
13476995916	greenhouse effect	absorption of infrared radiation by atmospheric gases and reradiation of the energy back to Earth	2
13476995936	greenhouse effect picture		3
13476995917	global change affects	rising sea levels, more fossil fuel extraction, more contamination, biogeochemical cycle altered, less biodiversity, emerging infectious diseases, overharvesting/ exploitation of plants and animals	4
13476995918	global climate change affects	more storm intensity, altered patterns of ocean circulation	5
13476995919	global warming affects	the warming of the oceans, land masses, and atmosphere of the earth, increased heat waves, reduced cold spells	6
13476995920	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 the molecule of CO2	7
13476995921	greenhouse warming potential calculation	calculated by the amount of infrared energy that a given gas can absorb and how long the molecule of gas can persist in the atmosphere	8
13476995922	Charles David Keeling	the first person to properly measure CO2, tested the levels of CO2 throughout the year and saw a change in seasonal concentrations	9
13476995923	Kyoto protocol	an international agreement that sets a goal for global emissions of greenhouse gases from all industrial countries to be reduced by 5.2% below their 1990 levels by 2012	10
13476995924	ocean acidification	the process by which an increase in ocean temperatures causes more CO2 to be converted to carbonic acid, which lowers the pH of the water and makes it more acidic	11
13476995925	ocean acidification (positive feedback loop)	it would still happen if CO2 wasn't a greenhouse gas, but warmer oceans absorb less CO2, therefore more CO2 ends up in the atmosphere and causes more global warming which causes oceans to warm in a continuous positive feedback loop	12
13476995926	carbon sequestration	an approach to stabilizing greenhouse gases by removing CO2 from the atmosphere	13
13476995927	methane natural source	comes from termite mounds and wetlands	14
13476995928	water vapor natural source	comes from trees through transpiration and wetlands	15
13476995929	nitrous oxides natural source	comes from wetlands and fire burning forests	16
13476995930	CO2 natural source	comes from termite mounds, wetlands, trees, and fire burning forests	17
13476995931	methane anthropogenic source	energy production and combustion, livestock digestion	18
13476995932	nitrous oxides anthropogenic source	most from agricultural soils (in fertilizers)	19
13476995933	CO2 anthropogenic source	combustion to generate electricity, for transportation, for homes and businesses, industrial processes	20
13476995934	water vapor	not a big greenhouse gas because it doesn't last long in the atmosphere and humans don't influence it much	21
