This ecology infographic example was created on the base of the infographics "Greenhouse gas emissions in the EU" from the Debating Europe website. [debatingeurope.eu/ wp-content/ uploads/ 2013/ 06/ TH_ 2_ social.png]
"A 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 temperature of the Earth; without them, Earth's surface would average about 33 °C colder, which is about 59 °F below the present average of 14 °C (57 °F)."
