9/6/21 warming of the surface and lower atmosphere of a planet (such as Earth or Venus) that is caused by conversion of solar radiation into heat in a process involving selective transmission of short wave solar radiation by the atmosphere, its absorption by the planet's surface, and reradiation as infrared which is absorbed and partly reradiated back to the surface by atmospheric gases Solar energy radiating back to space from the Earth's surface is absorbed by greenhouse gases and reemitted in all directions This heats both the lower atmosphere and the surface of the planetFormerly used as a refrigerant and as a propellant in aerosol cans;

The Kyoto Protocol is an international agreement adopted in 1997 that aimed to reduce carbon dioxide emissions and the presence of greenhouse gasesGreenhouse gases let the sun's light shine onto the Earth's surface, but they trap the heat that reflects back up into the atmosphere In this way, they act like the insulating glass walls of a greenhouse The greenhouse effect keeps Earth's climate comfortableGreenhouse gas definition, any of the gases whose absorption of solar radiation is responsible for the greenhouse effect, including carbon dioxide, methane, ozone, and the fluorocarbons
Definition of Greenhouse gas A greenhouse gas (sometimes abbreviated GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared rangeThis process is the fundamental cause of the greenhouse effect The primary greenhouse gases in Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozoneWe saw the family of past and possible future trajectories of greenhouse gas emissions and concentrations earlier in the course But what are the specific greenhouse gases involved, other than the obvious culprit CO 2, and where are these emissions actually coming from?What are the sectors of society and economy responsible for these emissions, the potential for reducingClimate change refers to significant changes in global temperature, precipitation, wind patterns and other measures of climate that occur over several decades or longer Discover an AZ glossary of concise scientific explanations to help readers better understand climate change from science to

However, the actual contribution of a greenhouse gas to atmospheric warming depends not only on its GWP, but also on its concentration At present, the concentrations of halogenated gases in the atmosphere are low and their combined radiative forcing is only about onefifth that of CO 2Global warming is mostly because of people burning things, like gasoline to make cars go and natural gas to keep houses warm But the heat from the burning itself only makes the world a tiny bit warmer it is the carbon dioxide from the burning which is the biggest part of the problem Among the greenhouse gases, the increase of carbon dioxide in the atmosphere is the main5/3/19 Switching to natural gas is an improvement over coal, but a transition to zeroemission sources of energy and heat (solar, wind, geothermal or nuclear) is needed to fully clean up our energy system Agriculture & Land Roughly onefifth of all global greenhouse gas emissions come from our use of land, mainly from deforestation and emissions

30/1/17 Greenhouse gases vary in not only their sources and the measures needed to control them, but also in how intensely they trap solar heat, how long they last once they're in the atmosphere, and how they react with other gases and ultimately get flushed out of the air› en español Scientists attribute the global warming trend observed since the mid th century to the human expansion of the "greenhouse effect" 1 — warming that results when the atmosphere traps heat radiating from Earth toward space Certain gases in the atmosphere block heat from escaping Longlived gases that remain semipermanently in the atmosphere and do not respondGreenhouse gases occur naturally and allow us to survive on Earth by warming air near Earth's surface Human activities are now increasing the amount of greenhouse gases in the atmosphere, which leads to changes in climate These changes are affecting many human activities, including agriculture GrEENHOUSE GAS BASICS
