Global Climate Change
changes in global patterns of rainfall and temperatures, sea level, habitats and the incidence of droughts, floods and storms, resulting from changes in the Earth's atmosphere, believed to be mainly caused by the enhanced greenhouse effect
Insolation
incoming solar radiation
Albedo
the proportion of the incident light or radiation that is reflected by a surface, typically that of a planet or moon.
Radiation
Energy that is radiated or transmitted in the form of rays or waves or particles.
Convection
The transfer of heat by the movement of a fluid or gas
Conduction
the transfer of heat by contact
The Greenhouse Effect
process by which certain gases all short wave radiation from the Sun to enter the atmosphere and get trapped
Short Wave Radiation
wavelengths of radiation emitted by the sun, especially ultraviolet, visible, and short infrared radiation
Long Wave Radiation
Radiation of energy from the Earth into the atmosphere and eventually into space
Water Vapor
gas phase of water
Carbon Dioxide (CO2)
gas with a density about 53% higher than that of dry air. It occurs naturally in Earth's atmosphere as a trace gas. Can increase due to human activity (i.e. burning fossil fuels)
Methane
second-largest contributor to global warming and atmospheric presence increases at 1% per year.
Chlorofluorocarbons (CFCs)
synthetic chemicals that destroy ozone and absorb long wave radiation
Global Dimming
A decline in the amount of light reaching the earth's surface because of increased air pollution, which reflects more light creating a cooling effect
Positive Feedback Loop
Loop that speeds up global warming
