A greenhouse gas sometimes abbreviated GHG is a gas that absorbs and emits radiant energy within the thermal infrared range. Greenhouse gases cause the greenhouse effect. This increase has occurred despite the uptake of more than half of the emissions by various natural "sinks" involved in the carbon cycle. Should greenhouse gas emissions continue at their rate in , global warming could cause Earth's surface temperature to exceed historical values as early as , with potentially harmful effects on ecosystems, biodiversity and human livelihoods. The next most common gases are carbon dioxide, nitrous oxides, methane, and ozone. Greenhouse gases are those that absorb and emit infrared radiation in the wavelength range emitted by Earth. Atmospheric concentrations are determined by the balance between sources emissions of the gas from human activities and natural systems and sinks the removal of the gas from the atmosphere by conversion to a different chemical compound or absorption by bodies of water.

Our need for energy has never been greater. Globally we use more energy than ever before, and the demand is rapidly growing. Economic expansion of emerging market economies, population growth and our increasing use of energy-consuming devices are among the most important contributing factors. Solar radiation consists of visible light as well as of ultraviolet , infrared and other types of radiation invisible to the human eye. About one-third of the radiation hitting Earth's atmosphere is reflected back out into space by clouds, ice, snow, sand and other reflective surfaces.

Carbon dioxide consists of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas. The current concentration is about 0. Because carbon dioxide is soluble in water, it occurs naturally in groundwater , rivers and lakes , ice caps , glaciers and seawater. It is present in deposits of petroleum and natural gas. Carbon dioxide is odorless at normally encountered concentrations. However, at high concentrations, it has a sharp and acidic odor.

Greenhouse gas

Group: Global Warming and Greenhouse effect. Global Warming:. Greenhouse Effect:. Is a process by which radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions. Since part of this re-radiation is back towards the surface and the lower atmosphere, ti results in an elevation of the average surface temperature above what it would be in the absence of the gases. Carbon cycle.

Brian E. Rose , University at Albany. This document uses the interactive IPython notebook format now also called Jupyter. The notes can be accessed in several different ways:. The climate system evolves in time under the influence of its own internal dynamics and because of external forcings such as volcanic eruptions, solar variations and anthropogenic forcings such as the changing composition of the atmosphere and land use change. The component of the climate system comprising liquid surface and subterranean water, such as oceans, seas, rivers, lakes, underground water, etc. The part of the Earth system comprising all ecosystems and living organisms including derived dead organic matter, such as litter, soil organic matter and oceanic detritus.

It considers their vulnerabilities and the capacities and limits of these natural and human systems to adapt to climate change and thereby reduce climate-associated risks together with options for creating a sustainable future for all through an equitable and integrated approach to mitigation and adaptation efforts at all scales.

Go to the " Carbon Dioxide " puzzle piece for more information about Human Influences on this gas. However, the biosphere, humans in particular, has had an increasingly greater impact on climate in recent decades. One way in which humans have affected the climate is by increasing emissions of greenhouse gases. Greenhouse gases absorb infrared long-wave, heat radiation. This is the form of the sun's energy reflected off the earth's surface.
