Term
Climate Change
Definition
a long-term change in the earth's climate, especially a change due to an increase in the average atmospheric temperature
Term
Global Warming
Definition
an increase in the earth's average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect.
Term
Climate
Definition
The pattern of weather conditions within a region over a long period of time,
Term
Weather
Definition
The condition of the atmosphere at a specific place and time
Term
Plate Tectonics
Definition
A theory where the structure of the earth's crust is split into plates explaining phenomena like Earthquakes.
Term
continental drift
Definition
the theory that states that continents moved slowly over geological time from Pangaea (single continent) to their current continent positions
Term
inter-glacial period
Definition
a geological interval of warmer global average temperature lasting thousands of years that separates consecutive glacial periods within an ice age
Term
Ice cores
Definition
Air bubbles from glaciers in order to see contents of air at certain time
Term
Proxy Record
Definition
Clues used to determine past climates
Term
Atmosphere
Definition
the gases that surround earth

Temperature
Humidity
Precipitation
Wind
Storms
Term
Layers of atmosphere in order and heat pattern
Definition
Troposphere, Stratosphere, Mesosphere, Thermosphere
--> down --> up --> down --> up
(pressure decreases with altitude)
Term
Conduction
Definition
transfer of thermal energy between neighboring molecules
Term
Convection
Definition
transfer of thermal energy by movements of layers within fluids
Term
Radiation
Definition
transfer of electromagnetic energy by waves travelling through a medium or empty space.
Term
Albedo
Definition
the proportion of the sun's radiation that is reflected by Earth back to the sun (long wave radiation)
Term
Natural Greenhouse Effect
Definition
Radiation from the sun passes through the Earth’s atmosphere and is absorbed by the Earth’s surface.
Becomes thermal energy and the Earth Warms-up
Earth emits lower-energy infrared radiation
Gases in the atmosphere trap radiation
GHGs in atmosphere absorb radiation and some is sent back to Earth surface.
Term
Infrared Radiation
Definition
electromagnetic radiation with wavelengths longer than visible light
Term
Ultraviolet Radiation
Definition
lectromagnetic radiation with a wavelength shorter than that of visible light
Term
Thermal Radiation
Definition
the thermal motion of charged particles in matter radiated electromagnetically
Term
Greenhouse gas
Definition
Water vapor, Carbon Dioxide, Methane, Ozone, Nitrious Oxides

a gas that contributes to the greenhouse effect by absorbing infrared radiation
Term
Anthropogenic Greenhouse Effect
Definition
The natural greenhouse effect however magnified by the greenhouse gas emissions of humans
Term
Positive Feedback Loop
Definition
A closed loop system, that enhances positive loop gain over time.
Term
Net Radiation budget
Definition
Solar Energy budget: +70% absorbed, 30 % reflected before earth, -70% radiated back
Term
Fossil Fuels
Definition
a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms.
Term
Carbon Source
Definition
any activity that emits Carbon Dioxide
Term
Carbon Sink
Definition
a forest, ocean, or other natural environment viewed in terms of its ability to absorb carbon dioxide from the atmosphere.
Term
Climate Forcing
Definition
the difference of radiant energy received by the earth and energy radiated back to space
Term
Climate Feedbacks
Definition
A process that acts to amplify or reduce direct warming or cooling effects.
Term
Mitigation
Definition
an energy imbalance imposed on the climate system either externally or by human activities.
Term
Carbon Offsets
Definition
Keep your lifestyle however, you pay a company to offset your carbon usage by doing things (though there is no way to track this)
Term
Emissions Trading (cap & trade)
Definition
When a cap of emissions is set in place on countries or organisations, and if one goes under their limit and one goes over they can trade "emissions"
Term
Carbon Tax
Definition
a tax on fossil fuels, especially those used by motor vehicles, intended to reduce the emission of carbon dioxide.
Term
Geoengineering
Definition
the deliberate large-scale manipulation of an environmental process that affects the earth's climate, in an attempt to counteract the effects of global warming.
Term
Carbon capture (sequestration)
Definition
Taking the carbon emissions and capturing it, turning it into a liquid/solid and pumping it back into the ground where it came from (coal mines etc.) "a natural or artificial process by which carbon dioxide is removed from the atmosphere and held in solid or liquid form."
