|
Global Change
|
refers to planetary-scale changes in the Earth system
|
|
|
Global Climate Change
|
can both refer to the observed century-scale rise in the average temperature of the Earth's climate system and its related effects, although climate change can also refer to any historic change in climate
|
|
|
Global Warming
|
the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth's climate
|
|
|
Solar Radiation
|
is radiant energy emitted by the sun, particularly electromagnetic energy. About half of the radiation is in the visible short-wave part of the electromagnetic spectrum. The other half is mostly in the near-infrared part, with some in the ultraviolet part of the spectrum
|
|
|
Greenhouse Effect
|
a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions
|
|
|
Foraminifera
|
a phylum or class of amoeboid protists, characterized by streaming granular ectoplasm that among other things is used for catching food, and commonly by an external shell, or test, made of various materials and constructed in diverse forms
|
|
|
Greenhouse Warming Potential
|
a relative measure of how much heat a greenhouse gas traps in the atmosphere. It compares the amount of heat trapped by a certain mass of the gas in question to the amount of heat trapped by a similar mass of carbon dioxide
|
|
|
Ice Coring
|
a core sample that is typically removed from an ice sheet, most commonly from the polar ice caps of Antarctica, Greenland or from high mountain glaciers elsewhere
|
|
|
Climate Feedbacks
|
processes that change as a result of a change in forcing, and cause additional climate change. An example of this is the "ice-albedo feedback." As the atmosphere warms, sea ice will melt
|
|
|
Carbon Capture/Sequestration
|
the process of capturing waste carbon dioxide (CO2) from large point sources, such as fossil fuel power plants, transporting it to a storage site, and depositing it where it will not enter the atmosphere, normally an underground geological formation
