Global climate: The average climate around the world

Geothermal energy: Heat from inside the Earth. People can use geothermal energy to heat buildings or produce electricity.
Guild
Guild: a formal association of people with similar interests.
Green Tag
Green Tag: A green tag or Renewable Energy Certificate (REC), represents the environmental attributes created when electricity is generated using renewable sources instead of fossil fuels such as coal, oil & natural gas. REC’s can be sold separately form their associated electricity & enable customers to "green" the electricity they consume from their retail power supplier(s).

Global Warming Potential (GWP)
Global Warming Potential (GWP): This is the impact of greenhouse gas emissions which contribute to the "greenhouse effect". Elevated concentrations of greenhouse gases contribute to global warming & increased climate variability. Also referred to as Climate change.
Global Warming
Global Warming: Also known as the Greenhouse Effect most scientists believe global warming is happening right now. When too many greenhouse gasses such as carbon dioxide and methane are trapped in the atmosphere, the temperature on the Earth rises causing the ice at the north and south poles to melt. This raises the water level in the oceans and different places on the earth slowly get hotter or colder. If it goes on long enough, global warming could change rainforest’s to deserts and dry areas to wet ones.
Geothermal Energy
Geothermal Energy: Energy we get directly from the Earth, usually in the form of heat. Volcanoes are an excellent source of geothermal energy.
Genetically Engineered Organism (GEO)
A Genetically engineered organism is an organism with a directly modified genome through biotechnology.
Gaia
Gaia: goddess of the earth and mother of Cronus and the Titans in ancient mythology.
