Adaptation
The International Panel on Climate Change (IPCC) defines adaptation as the adjustment in natural or human systems in response to actual or expected climatic stimuli or their effects, which moderates harm or exploits beneficial opportunities.
Global Climate Change
Global climate change is change recorded over an extended length of time (decades or longer) with regards to precipitation, temperature, or wind caused by natural and/or manmade factors.
Greenhouse Gases
Greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxides, and chlorofluorocarbons (CFC or "Freon"). With the exception of water vapor, increases in these greenhouse gases are produced largely by human activities. These gases let in most of the incoming solar radiation that heats Earth's surface, yet prevent part of the outgoing thermal radiation from escaping to space, thus trapping some of the surface heat energy.
Mitigation
To mitigate something means to reduce its affect. The Intergovernmental Panel on Climate Change (IPCC) defines mitigation as an intervention to reduce the sources or enhance the sinks of greenhouse gases.
