 The greenhouse effect is the way in which heat is trapped close to Earth's surface by "greenhouse gases" These heattrapping gases can be thought of as a blanket wrapped around Earth, keeping the planet toastier than it would be without them Greenhouse gases include carbon dioxide, methane, and nitrous oxidesGREAT LAKES CLIMATE CHANGE CURRICULUM GREENHOUSE GASES BACKGROUND The Earth's climate depends on the amount of solar radiation received and the atmospheric abundance of clouds and greenhouse gases The main greenhouse gases are carbon dioxide, methane, chlorofluorocarbons, nitrous oxide, water vapor, and ozone Much of the highenergy,Climate change includes both humaninduced global warming and its largescale impacts on weather patterns There have been previous periods of climate change, but the current changes are more rapid than any known events in Earth's history The main cause is the emission of greenhouse gases, mostly carbon dioxide (CO 2) and methaneBurning fossil fuels for energy

Climate change greenhouse gases graph- Playing it conservative with the EU figures and extrapolating from the scarce figures that exist for other countries, we can estimate that at least 56% of emissions are due to food transport, 810% due to food processing and packaging, around 12% due to refrigeration, and 12% due to retailClimate change widespread, rapid, and intensifying – IPCC — GENEVA, Aug 9 – Scientists are observing changes in the Earth's climate in every region and across the whole climate system, according to the latest Intergovernmental Panel on Climate Change (IPCC) Report, released today

Greenhouse gases emitted by human activities alter Earth's energy balance and thus its climate Humans also affect climate by changing the nature of the land surfaces (for example by clearing forests for farming) and through the emission of pollutants that affect the amount and type of particles in the atmosphereAgriculture's greenhouse gas emissions cows and grazing land In Australia, 'agriculture' contributes around 13% of our greenhouse gas emissions each year By weight, about half of the agricultural sector's emissions – or 42% – are methane Most of this is the methane produced by cows and other livestock due to the fermentation ofTo prevent severe climate change we need to rapidly reduce global greenhouse gas emissions The world emits around 50 billion tonnes of greenhouse gases each year measured in carbon dioxide equivalents (CO 2 eq) 1 To figure out how we can most effectively reduce emissions and what emissions can and can't be eliminated with current technologies, we need to first

At its 47th Session on 1316 March 18, the IPCC adopted Decision IPCCXLVII9 where TGICA was renamed to Task Group on Data Support for Climate Change Assessments (TGData) with new Terms of Reference for TGData as well as Guidance for the Data Distribution Centre (DDC) Membership TGData members were selected during the 56th Session ofGreenhouse gases (ghg), although they constitute only a small fraction of the atmosphere, their impact on climate is very important Without greenhouse gases, the Earth's surface would have an average temperature of 18oC, too cold for life as we know it Instead the average temperature at the surface of the Earth is approximately 15oCThe 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 matter
