5 major greenhouse gases and their sources 1 Carbon dioxide Carbon dioxide has the chemical formula CO2 It is a very harmful and damaging greenhouse gas This gas is released into our atmosphere largely through the burning of fossil fuels such as coal, oil and natural gasFluorinated 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 SF6Fluorinated gases Hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, and nitrogen trifluoride are synthetic, powerful greenhouse gases that

Identify key factors influencing Earth's climate, including solar radiation and the atmospheric concentrations of greenhouse gases (such as carbon dioxide) Describe how and why Earth's climate has changed over time Summarize the concept of climate change and the factors that contribute to itGreenhouse gases are gases—like carbon dioxide (CO 2), methane, and nitrous oxide—that keep the Earth warmer than it would be without themThe reason they warm the Earth has to do with the way energy enters and leaves our atmosphereWhen energy from theGreenhouse Gases Greenhouse gases trap heat in the atmosphere, which makes the Earth warmer People are adding several types of greenhouse gases to the atmosphere, and each gas's effect on climate change depends on three main factors
Untitled Most important human activities emit greenhouse gases (GHGs) Emissions started to rise dramatically in the 1800s due to the Industrial Revolution and changes in land use Many greenhousegasemitting activities are now essential to the global economy and a fundamental part of modern life Carbon dioxide from the burning of fossil Greenhouse Gases Carbon Dioxide, Nitrous Oxide, Methane Share of Global GHG Emissions 103% Virgin Amazon rainforest borders an area of jungle destroyed to make way for farms in Brazil Deforestation, forest degradation and decay, forest and peat fires and other land use changes are responsible for over 10 percent of global emissions These methods of energy production emit no greenhouse gases once they are up and running In most states, alternatives are available for customers who want to purchase green power (50 to 100 percent renewable energy) For a complete list of green power options, visit the US Department of Energy's Green Power Network website Top of Page
First week only $499! Greenhouse gases consist of chemical compounds and make up a significant portion of the atmosphere These gases act as insulation for the Earth and trap heat radiated by the Sun that would otherwise be sent back out into space Without certain gases in the atmosphere, life would not have been able to evolve on Earth to what we see todayGreenhouse gases absorb this infrared radiation to trap heat in the atmosphere Greenhouse gases can absorb and emit infrared radiation within the thermal infrared range The major greenhouse gases are Carbon dioxide (CO 2 ), Water vapour (H 2 O), Methane (CH 4 ), Nitrous oxide (N 2 O), Chlorofluoro carbons and perfluorocarbons (CFCs and PFCs)

How To Stop Global Warming The 8 Best Solutions
In general, greenhouse gases constitute just almost 1% of the total gases present in the atmosphere Their concentrations are dependent on the balance between the "sources" and "sinks" that function to create and destroy these gases respectivelyAnthropogenic activities tend to increase these concentrations by either introducing new types of gases in the air or FIGURE 32 Additional radiative forcing of principal greenhouse gases from 1990 to 30 for different emission rates The horizontal axis shows changes in greenhouse gas emissions ranging from completely eliminating emissions (100 percent) to Nitrous oxide comes in at No 4 on the list of worst greenhouse gases This gas is used as an aerosol spray propellant, anesthetic and recreational drug, oxidizer for rocket fuel, and to improve engine power of automotive vehicles It is 298 times more effective at trapping heat than carbon dioxide (over a 100 year period)

, etc) and a list of any additional GHGs included in the inventory p121; Although carbon dioxide is often considered the worst greenhouse gas, it is not actually true However, since there is more carbon dioxide in the atmosphere than any other greenhouse gases emitted by humans (only topped by water vapor), it does have the most obvious impact 3 Methane Methane is the next on our top 5 list of greenhouse gasesCarbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2 O), Ozone (O 3), and chlorofluorocarbons (CFCs), along with water vapour are known as greenhouse gases Due to human intervention, the amount of greenhouse gases in the atmosphere has increased remarkably causing the greenhouse effect

Answer to 1 List three greenhouse gases 2 Which is the most important of these gases in terms of amplification of climate effecIf you add CO 2 from fossil fuel burning, deforestation, and other minor sources, this comes to a little more than threefourths of the net greenhouse radiative forcing by humancaused emissions That means, however, that a nontrivial fraction of the effect is coming from other gases Another positive aspect supporting carbon sequestration is that it also affects other greenhouse gases In particular, methane (CH4) and nitrous oxide (N2O) can also be sequestered in agricultural activities such as grazing and the growing
