Arctic/Polar Amplification Effect
The Arctic/Polar Amplification Effect is mainly caused by a combination of a few things. The chief components include the magnitude of change regarding ice extent and snow cover loss allows for a more dramatic change in climate architecture of the polar region. This also relates to the amount of land in the northern hemisphere verses the southern hemisphere.

Atlantic Multidecadal Oscillation (AMO)
The AMO is an ongoing series of long-duration changes in the sea surface temperature of the North Atlantic Ocean, with cool and warm phases that may last for 20-40 years at a time and a difference of about 1°F between extremes. These changes are natural and have been occurring for at least the last 1,000 years. Source: http://www.aoml.noaa.gov/phod/amo_faq.php

Atmospheric Aerosols
Aerosols are tiny particles that are capable of suspending in the atmosphere. Most come from natural means such as dust storms, volcanoes, fires, or even vegetation and sea spray (sea salt released into the atmosphere). Human activity also contributes aerosol pollution through the alteration of natural surface cover, industrial pollutants, and the burning of fossil fuels.

Atmospheric Composition
Understanding Atmospheric Composition is both simple and handy in understanding how mankind can influence climate. Many people think the atmosphere is just too big for humans to influence? It sounds like a reasonable statement, until you realize that you don't need to change the whole atmosphere to change climate... you just need to change a little bit of it.

Attribution
Climate attribution literally has to do with what causes something, or "to explain by indicating a cause". With regard to climate and weather it is important to understand the differences between what attribution can be assigned to climate and/or weather events at a given moment, or over a span of time. The longer the span of time, the more the attribution moves away from weather and towards climate, and vice versa.

Carolyn Revelle, What My Father Really Said
The disturbing story of how scientists that work for special interests can tarnish the reputation of a 'Truly Great Scientist' Roger Revelle. This is a story of distortion that has resonated for years in the global warming debate. The facts and the evidence are clear. Fred Singer, Richard Lindzen, John Coleman and anyone else that supports the deception are guilty of more than deception.

Climate Feedback/Sensitivity
Climate Feedbacks: An interaction mechanism between processes in the climate system is called a climate feedback, when the result of an initial process triggers changes in a second process that in turn influences the initial one. A positive feedback intensifies the original process, and a negative feedback reduces it.

Climate Forcing
Climate forcing has to do with the amount of energy we receive from the sun, and the amount of energy we radiate back into space. Variances in climate forcing are determined by physical influences on the atmosphere such as orbital and axial changes as well as the amount of greenhouse gas in our atmosphere.

Climate Models
GCM's (General Circulation Models) or sometimes mistakenly referred to as Global Climate Model, Typically refers to a three-dimensional model of the global atmosphere used in climate modeling (often erroneously called “Global Climate Model”). This term often requires additional qualification (e.g., as to whether or not the atmosphere is fully coupled to an ocean as in AOGCM, which stands for Atmosphere-Ocean General Circulation Model.
