|---|---|---|---|---|---|
| Global Change | any chemical, biological, or physical change in the properties of the planet.
🗑
|
||||
| Global Climate Change | a difference between recent and long-term average weather (climate) of the Earth
🗑
|
||||
| Global Warming | one aspect of climate change; the warming of the Earth’s oceans, land masses, and atmosphere.
🗑
|
||||
| Solar radiation and Greenhouse gases do what? | make our planet warm
🗑
|
||||
| Earth's solar energy | The ultimate source of almost all energy on Earth is the Sun. When radiation from the Sun hits the atmosphere, clouds, and surface of the earth, almost ⅓ is reflected away back into space.
🗑
|
||||
| The "Greenhouse" Effect | Much of this infrared radiation is “taken up” by the greenhouse gases in the atmosphere.
This warms these gases, and then some infrared energy is radiated back to Earth.
Collectively, these processes cause warming on the planet.
🗑
|
||||
| Atmospheric Greenhouse Gases | Water vapor (most abundant), Carbon dioxide, Methane, Nitrous oxide, Chlorofluorocarbons, Ozone
🗑
|
||||
| Natural sources of Greenhouse gases | Volcanic eruptions: Carbon dioxide
Decomposition: Methane
Denitrification: Nitrous oxide
?: Water vapor
🗑
|
||||
| Anthropogenic sources of greenhouse gases | Burning of fossil fuels, Agricultural practices, Deforestation, Landfills, Industrial production
🗑
|
||||
| An increased atmospheric CO2 level in the atmosphere | causes a greater capacity for warming; i.e., greenhouse effect
🗑
|
||||
| When the Earth experiences higher temperatures: | the oceans warm and cannot “hold” as much CO2 gas. As a result, the oceans release CO2 into the atmosphere.
🗑
|
||||
| Cyclical effect | Warming Earth causes CO2 to be released by the ocean --> Higher CO2 concentrations lead to a warmer Earth through the Greenhouse Effect --> Continued warming causes more CO2 to be released by the ocean --> repeat
🗑
|
||||
| The fundamental basis for climate change: | (1) greenhouse gas concentrations are increasing and (2)this will lead to global warming.
🗑
|
||||
| The Kyoto Protocol Agreement | Emissions of greenhouse gases from industrialized countries will be reduced to 5.2% below their 1990 levels by 2012.
🗑
|
||||
| Carbon Sequestration | Involves taking the greenhouse gas CO2 out of the atmosphere.
🗑
