Greenhouse gases in the atmosphere, including water vapour, carbon dioxide, methane, and nitrous oxide, act to make the surface much warmer than this because they absorb and emit heat energy in all directions (including downwards), keeping Earth's surface and lower atmosphere warm Figure B1 Without this greenhouse effect, life as we know it could not have evolved onFluorinated Gases (HFCs, PFCs, SF 6) Fluorinated gases are emitted in smaller quantities than the other greenhouse gases, but what they lack in volume they can make up in potency and long lifespans in the atmosphere, ranging from 1270 years for HFCs to ,000 years for PFCs and about 3,0 years for SF6Gases of the Atmosphere Match each layer with its description _____ exosphere _____ ionosphere _____ mesosphere _____ stratosphere _____ thermosphere _____ troposphere A closest to Earth, where

Atmosphere diagram greenhouse gases-Atmospheric gases Water vapor is the Earth's most important natural greenhouse gas Water vapor and clouds cause most of the Earth's natural greenhouse effect and account for about 90% of the total heatretaining capacity of the atmosphere Greenhouse gases can also reabsorb solar radiation reflected or reemitted from Earth's surface,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 2 Because of overlapping absorptions, total radiative

This diagram shows that the array of radiation, often called the electromagnetic spectrum, varies from the shortest wavelength gamma rays to the longest radio waves Each one of these types of radiation travels through a vacuum at the same speed of light, however, each type of radiation has its own wavelength and frequency Moreover, and this is very important, each packet of radiationEPA has two key programs that provide data on greenhouse gas emissions in the United States the Inventory of US Greenhouse Gas Emissions and Sinks and the Greenhouse Gas Reporting Program The programs are complementary, providing both a higherlevel perspective on the nation's total emissions and detailed information about the sources and types of emissions from individual facilities The data in EPA's US Greenhouse GasCarbon dioxide (CO 2) is the primary greenhouse gas emitted through human activities In 19, CO 2 accounted for about 80 percent of all US greenhouse gas emissions from human activities Carbon dioxide is naturally present in the atmosphere as part of the Earth's carbon cycle (the natural circulation of carbon among the atmosphere, oceans, soil, plants, and
Carbon dioxide and methane (CH4) are two types of greenhouse gases that trap energy from the Sun in the atmosphere, which causes the planet to warm Without any greenhouse gases, the Earth would be too cold to sustain life at current levels, but with the current rapid increase of greenhouse gases, the climate is warming too much Humancaused carbon emissions haveNitrous oxide, N 2 O;Greenhouse Gases The three most common types of greenhouse gases are Carbon Dioxide (CO 2) Carbon dioxide enters the atmosphere through the burning of fossil fuels (oil, natural gas, and coal), solid waste, trees and wood products, and as a result of other chemical reactions such as making cementCarbon dioxide is removed from the atmosphere and stored when it is absorbed

Some of the greenhouse gases in the atmosphere are caused by humans Whenever we burn anything, such as— gasoline in our cars and trucks, jet fuel in our planes, coal in our factories or powerplants, trees to clear the land for farming —we pollute our atmosphere with carbon dioxide and carbon monoxide Although carbon monoxide does not act as a greenhouse gasGreenhouse gases are gases in Earth's atmosphere that trap heat They let sunlight pass through the atmosphere, but they prevent the heat that the sunlight brings from leaving the atmosphere The main greenhouse gases are Water vapor;474 KB 18 AQAL Group variwide chart Worldwide Co2 emissionsjpg 3,315 ×
Greenhouse gas, any gas that has the property of absorbing infrared radiation (net heat energy) emitted from Earth's surface and reradiating it back to Earth's surface, thus contributing to the greenhouse effect Carbon dioxide, methane, and water vapour are the most important greenhouse gases (To a lesser extent, surfacelevel ozone, nitrous oxides, and fluorinated gasesQ2 Diagram A shows LW (IR) terrestrial radiation "bouncing off" (or reflecting) the gases in the atmosphere and being sent back to Earth's surface (ie being reflected back to the surface by the gases without being absorbed by them) Is this an accurate depiction of how the Greenhouse Effect works?A diagram, answer opinion questions, and perform a skit to understand Earth's energy balance Students will learn that most of the energy on Earth originates from the sun They will also learn what happens to the energy once it reaches Earth's atmosphere Students will be introduced to the concept of greenhouse gases The activity will close with a discussion of natural vs human
Greenhouse gases come from all sorts of everyday activities, such as using electricity, heating our homes, and driving around town The graph to the right shows which activities produce the most greenhouse gases in the United States These greenhouse gases don't just stay in one place after they're added to the atmosphere As air moves around the world, greenhouse gases become globally mixed, which means the concentration of a greenhouse gasCarbon dioxide, CO 2;Today's atmosphere absorbs more than 3 watts of incoming solar energy over each square meter of Earth's surface According to NOAA's 19 Annual Greenhouse Gas Index (right axis), the combined heating influence of all major greenhouse gases has increased by 45% relative to 1990 Graph by NOAA Climategov based on data from NOAA ESRL

If the atmosphere is like a greenhouse, what parts of it function as the "glass"?Greenhouse effect, a warming of Earth's surface and troposphere (the lowest layer of the atmosphere) caused by the presence of water vapour, carbon dioxide, methane, and certain other gases in the air Of those gases, known as greenhouse gases, water vapour has the largest effect The origins of the term greenhouse effect are unclearA greenhouse gas (sometimes abbreviated GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range This process is the fundamental cause of the greenhouse effect The primary greenhouse gases in the Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone Greenhouse gases greatly affect the

This chart shows the change in global greenhouse gas emissions over time Greenhouse gases are measured in 'carbon dioxideequivalents' (CO 2 e) Today, we collectively emit around 50 billion tonnes of CO 2 e each year This is more than 40% higher than emissions in 1990, which were around 35 billion tonnesOver time, it leaks into the atmosphere Current concentrations of SF 6 in the atmosphere are small, but SF 6 has a lifetime of 3,000 years, and per kilogram it is 36,000 times more powerful than CO 2 as a greenhouse gas!!The 'greenhouse effect' is the warming of climate that results when the atmosphere traps heat radiating from Earth toward space Certain gases in the atmosphere resemble glass in a greenhouse, allowing sunlight to pass into the 'greenhouse,' but blocking Earth's heat from escaping into space The gases that contribute to the greenhouse effect include water vapor,
The atmosphere protects life on Earth by absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation) The common name given to the atmospheric gases used in breathing and photosynthesis is air By volume, dry air contains 7809% nitrogen, 95% oxygen, 093% argon, 0039% carbon dioxide, and small amounts of other gasesAnd N 2O increases from 13
