Graphic The relentless rise of carbon dioxide Ancient air bubbles trapped in ice enable us to step back in time and see what Earth's atmosphere, and climate, were like in the distant past They tell us that levels of carbon dioxide (CO 2) in the atmosphere are higher than they have been at any time in the past 400,000 years Greenhouse gases that occur both naturally and from human activities include water vapor, carbon dioxide (CO 2 ), methane (CH 4 ), nitrous oxide (N 2 O) and ozone (O 3) Other greenhouse gases have essentially no natural sources, but are side products of industrial processes or manufactured for human purposes such as cleaning agents Graph by NOAA Climategov based on data from NOAA ESRL According to the 19 AGGI report, the combined heating influence of the longlived, humanproduced greenhouse gases is 314 Watts for every square meter of Earth's surface Just over 80 percent of that is due to carbon dioxide (66%) and methane (16%)

Why greenhouse gases are increasing
Why greenhouse gases are increasing-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 tonnesToday, it's up to nearly 400 ppm (see graph at right), and the amount is still rising Along with other greenhouse gases, this extra CO 2 is trapping heat and causing the climate to change Before people had thermometers, indeed before any temperatures were recorded, the
This Graph Shows How The Total Amount Of Greenhouse Gas Emissions Has Been Increasing Around The World Greenhouse Gases Climate Change Greenhouse Gas Emissions
Global warming is the unusually rapid increase in Earth's average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels The global average surface temperature rose 06 to 09 degrees Celsius (11 to 16° F) between 1906 and 05, and the rate of temperature increase has nearly doubled in the last 50 years The annual increase in atmospheric N 2 O in a given year is the increase in its abundance (mole fraction) from January 1 in that year to January 1 of the next year, after the seasonal cycle has been removed (as shown by the black lines in the figure above) keeling curve graphic CO2 traps twothirds of the heat retained on the Earth's surface by greenhouse gases, and this warming effect has increased by The 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, In its Global Energy Review, published on Tuesday, the IEA found that global carbon emissions from energy use, which accounts for the great majority of greenhouse gas emissions, were on course to Gases that trap heat in the atmosphere are called greenhouse gases This section provides information on emissions and removals of the main greenhouse gases to and from the atmosphere For more information on the science of climate change and other climate forcers, such as black carbon, please visit Climate Change Science
Greenhouse gas emissions by sector in the EU According to the fifth assessment report by the Intergovernmental Panel on Climate Change (IPCC), it is extremely likely that human activities over the past 50 years have warmed our planet These activities include for example the burning of coal, oil and gas, deforestation and farmingKey Message 3 Many climate change impacts and associated economic damages in the United States can be substantially reduced over the course of the 21st century through globalscale reductions in greenhouse gas emissions, though the magnitude and timing of avoided risks vary by sector and region The effect of nearterm emissions mitigation on In the United States, greenhouse gas emissions caused by human activities increased by 2 percent from 1990 to 19 Since 05, however, total US greenhouse gas emissions have decreased by 12 percent

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 gas like carbon dioxide is roughly the same no matterCarbon Dioxide CO2 1 100* Methane CH4 25 12 Nitrous Oxide N2O 265 121 Chlorofluorocarbon12 (CFC Fluorinated gases (FGases) Chart B11 Fgas Emissions by Scottish Government Sector, 1990 to 17 Values in MtCO2e Main Points F gases are the most potent greenhouse gases with high global warming potentials but they are emitted in very small quantities As a result, they contribute less to global warming than the other greenhouse gases in
