Global Warming Terms Mid-Term Study Guide Malthusian population model ( ) where P 0  = Initial Population, r = growth  rate, t = time. Sometimes called the simple exponential growth model, is essentially  exponential growth based on a constant rate of compound interest. More Developed Countries (MDC)- is used to categorize countries with developed  economies in which the tertiary and quaternary sectors of industry dominate. Less Developed Countries (LDC)-opposite of MDC Greenhouse Gases- Gases that absorb infrared radiation (H2O, CO2, CH4, N2O,  CFC’s, O3):  Sulfur Dioxide, Ozone, Carbon Dioxide, Methane, Water  Vapor, CFC’s, Nitrous Oxide Greenhouse Effect- Well-established theory stating that some of the long-wavelength  (primarily infrared) radiation emitted by the Earth is absorbed by gases in the  atmosphere, thus warming the atmosphere. (Discovered by Jean-Baptiste Fourier in  1827.) Enhanced Greenhouse Effect- greenhouse effect attributed to greenhouse gases  such as CO2, CH4 that are increasing as a result of human activity. Global Warming- Theory that global temperatures will increase as a result of the  enhanced greenhouse effect. (Theory first proposed by Svante Arrhenius in 1896.) Black Body Radiation- Bodies that have surfaces that absorb all radiation  implemented upon them – any black body that is not at absolute 0 will emit energy to  its surroundings Albedo- (a) fraction of solar radiation that is reflected back to space. Earth’s  planetary albedo is about 0.3 Milankovitch Theory- identifies three types of variation in the Earth's orbit around the  Sun which could act as mechanisms to change the global climate. These include  changes in the tilt of the Earth’s axis (obliquity), changes in the shape of Earth's orbit  (eccentricity) and the shifting of the equinoxes (precession).   It also creates  alterations in the seasonality of solar radiation that reaches Earth’s surface.
