Climate Impacts

Climate Impacts  

The accumulation of greenhouse gases in the atmosphere due to fossil fuel combustion, land use change, and other anthropogenic activities may have begun to change the global climate system (Houghton ...
dust storm

dust storm  

A strong wind that blows fine dust across the surface of a desert, which can significantly reduce visibility and adversely affect communications and agriculture. Contrast sand storm. See also haboob.
Earth System Science

Earth System Science  

Earth System Science (ESS) seeks to understand major patterns, processes, and interactions of the main components of planet Earth—the atmosphere, oceans, fresh water, rocks, soils, and biosphere ...
Extreme Events

Extreme Events  

Among the possible consequences of global climate change are changes in the severity and frequency of extreme events such as floods, droughts, tropical cyclones, and severe thunderstorms. [See ...
general circulation model

general circulation model  

(GCM)A computer simulation of the general circulation of the atmosphere for purposes of climatological studies. The atmosphere is contained within a notional three-dimensional grid and its condition ...
global warming

global warming  

The gradual increase in the overall temperature of the earth's atmosphere due to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.
greenhouse effect

greenhouse effect  

Reference type:
Overview Page
The trapping of the sun's warmth in a planet's lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the ...
information technology

information technology  

Reference type:
Overview Page
The study or use of computers, telecommunication systems, and other devices for storing, retrieving, and transmitting information (2). See also information theory. IT abbrev.
integrated assessment

integrated assessment  

An assessment that brings together data about the past, current, and future condition of ecosystems, the impact of humans on the ecosystems, and the effects of environmental change on humans. This ...
International Institute For Applied Systems Analysis

International Institute For Applied Systems Analysis  

(Iiasa)A non‐governmental research organization located near Vienna in Austria, that conducts interdisciplinary scientific studies on environmental, economic, technological, and social issues in the ...
IPCC: Intergovernmental Panel on Climate Change

IPCC: Intergovernmental Panel on Climate Change  

The Intergovernmental Panel on Climate Change (IPCC) was established in 1988 by two United Nations organizations, the World Meteorological Organization (WMO) and the United Nations Environment ...
Modeling of Natural Systems

Modeling of Natural Systems  

The Earth's natural system encompasses the totality of the atmosphere, hydrosphere, biosphere, and geosphere and their interactions. Thus it spans very many variables, time scales, and spatial ...
ocean current

ocean current  

Large-scale water movement in an ocean, arising from three main causes: (a) wind stresses acting on the surface of the sea; (b) tidal motion caused by the variable attractions of the Sun and Moon; ...
Ocean-Atmosphere Coupling

Ocean-Atmosphere Coupling  

Ocean-atmosphere coupling is a concept of climate dynamics essential for understanding a large number of climate phenomena including the El Niño–Southern Oscillation (ENSO) and climate variability on ...
oceanography

oceanography  

Reference type:
Overview Page
N. the study of the sea, embracing and integrating all knowledge pertaining to the sea and its physical boundaries, the chemistry and physics of seawater, and marine biology.
scenario

scenario  

A description of how a situation might develop, based on a particular set of assumptions and factors, which is used to evaluate available options and select ways of dealing with uncertainty. See also ...
water Vapor

water Vapor  

The gaseous form of water, present in the atmosphere in varying amounts. It is an intermediate stage in the hydrological cycle. Water vapour in the atmosphere represents 0.01% of the total water ...
weather Forecasting

weather Forecasting  

The prediction of future weather for a place and over a specified time period, based on knowledge of meteorological principles and processes, and information about current and recent weather ...
Younger Dryas

Younger Dryas  

A stadial or relatively cold period from about 12 900 to 11 600 years ago, which interrupted the warming of the Earth after the last ice age.
