level questions: Climate change

Question	Answer
Is the range of global phenomena caused by burning fossil fuels that add heat-trapping gases to the Earth's atmosphere.	Climate Change.
Is used interchangeably with climate change, specifically refers to Earth's upward trend of temperature since the 20th century. Is generally defined as the general warming effect caused by greenhouse gases in the atmosphere. Keeps the planet warm and prevents warm air from leaving the planet.	Global warming
Global warming is generally defined as the general warming effect caused by: absorb infrared radiation that enters the atmosphere and radiate it to the Earth's surface as heat, thereby warming the earth.	greenhouse gases in the atmosphere.
The greenhouse gases absorbs what that enters the atmosphere and radiate it to the Earth's surface as heat, thereby warming the earth?	infrared radiation
Some common greenhouse gases that contribute to global warming include naturally occurring gases such as:	Carbon dioxide (CO2), methane (CH4), and nitrous oxides (NOx), and man-mage gases such as chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6).
What cause adverse global warming:	Man-made greenhouse gases and the increase in concentration of natural greenhouse gases
What is also pointed at as a culprit to this adverse phenomenon (global warming):	Deforestation
When forest land is destroyed, what thus increase the levels of long-wave radiation and trapped heat.	CO2 is released into the air.
When forest land is destroyed, COs is released into the air, thus:	increasing the levels of long-wave radiation and trapped heat.
What causes dilution of salt in the ocean and disruption of natural ocean currents. is one example of several effects of climate change already felt and observed.	the melting of ice caps in the polar regions of the Earth
Control temperatures by bringing warmer currents into cooler areas and cooler currents into warmer areas.	Ocean currents
Ocean currents control temperatures by:	bringing warmer currents into cooler areas and cooler currents into warmer areas.
The melting ice caps also affect what? the ratio of light reflected by any part of the Earth's atmosphere.	albedo
What has the highest albedo level, reflects sunlight back into space making the Earth cooler.	Snow
When snow melts (with the concept of albedo), what happens to the earth's temperature:	rises resulting in climate change.
What only appear on warmer months, but since there is a rise in global temperatures, they started to appear all year-round, chewing on spruce trees and thus leaving the forest damaged.	Spruce bark beetles in Alaska
What are also decreasing in number because the melting of the polar ice caps has caused them to starve and lose habitats.	polar bears
Diseases have also spread due to:	climate change
What greatly increased which can possibly displace disease-carrying insects, crucial pollinators, and crop pests into new areas.	Migration distances for many migratory species
Greater distances also mean what in order for animals to survive:	greater lengths to go to
What is maintained at the stratosphere as protection from the suns's harmful ultraviolet rays.	A thin layer of ozone (O3)
only a thin layer is needed (O3) because when there is higher O3 concentration, what happens? B.) in this case O3 becomes:	meteorological parameters, i.e. temperature and wind, brings down O3 in the troposphere and causes respiratory problems in humans. b.) pollutants
The production of obnoxious Cl which is very reactive to the point of destroying how many molecules of O3 in the stratosphere:	100, 000
