Borehole
Natural environment; Climate change
Any exploratory hole drilled into the Earth or ice to gather geophysical data. Climate researchers often take ice core samples, a type of borehole, to predict atmospheric composition in earlier ...
Feedback mechanisms
Natural environment; Climate change
Factors which increase or amplify (positive feedback) or decrease (negative feedback) the rate of a process. An example of positive climatic feedback is the ice-albedo feedback.
Parts per trillion (PPT)
Natural environment; Climate change
Number of parts of a chemical found in one trillion parts of a particular gas, liquid or solid.
Atmosphere
Natural environment; Climate change
The gaseous envelope surrounding the Earth. The dry atmosphere consists almost entirely of nitrogen (78.1% volume mixing ratio) and oxygen (20.9% volume mixing ratio), together with a number of trace ...
Carbon dioxide equivalent
Natural environment; Climate change
A metric measure used to compare the emissions from various greenhouse gases based upon their global warming potential (GWP). Carbon dioxide equivalents are commonly expressed as "million metric ...
