Troposphere Not Warming
This is a common denialist/skeptic meme. The reality is that while there are significant complexities in the tropospheric measurements and models, homogenized analysis indicates that the troposphere is doing what is expected of it in accord with the various models and general expectations.

Volcanoes Emit more CO2 than Mankind
This is a pervasive myth that continues to circulate. The idea that volcanoes put out more CO2 than mankind through human industrial output is patently false. Volcanoes put out around 0.2 Gt (200 million tons of CO2). The facts are clear and measured. As of 2010, humans put out on average of around 27Gt (Twenty Seven 'Gigatons') of CO2 per year. That's 2,700 million tons compared to natural cycles 200 million ton output.

1958 - Frank Capra warns of Global Warming
In 1958, Director Frank Capra made a movie for Bell Labs to explain the expected effects of 'Global Warming'. This was shortly after Revelle's paper came out. Capra, was also a scientist who graduated from California Institute of Technology in 1918 and did many science films for education.

1989 - Margaret Thatcher
Margaret Thatcher delivered a speech in 1989 that was powerful, compelling and succinct. She accurately described the potentials for mankind in reasoned tones if we did not address global warming. Themes: Agriculture, Energy, Environment, Foreign policy (general discussions), Foreign policy (development, aid, etc), Foreign policy (International organizations), Science and technology, Transport

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.

Antarctic Ice Melt
Antarctica is melting, not growing. In fact the ice mass is dropping at an accelerating rate due to multiple factors including accelerated glacial ice calving rates. The loss of sea based ice allows the Antarctic ice to move faster towards the ocean resulting in an increased rate of loss of the Antarctic ice.

Antarctic Oscillation (AAO)
The Antarctic Oscillation (AAO) is a measure of the pressure gradient between the polar and subpolar regions of the Southern Hemisphere. Term was introduced by Thompson and Wallace (2000).

Arctic Ice Melt
It is important to understand that ice mass and ice extent are two entirely different animals when it comes to understanding what is happening in the Arctic. The ice mass at the North Pole is rapidly diminishing. The effects of global warming on the Arctic ice is more pronounced due to the Arctic Amplification effect.

Arctic Oscillation (AO)
The Arctic Oscillation (AO) is a large scale mode of climate variability, also referred to as the Northern Hemisphere annular mode. The AO is a climate pattern characterized by winds circulating counterclockwise around the Arctic at around 55°N latitude.

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.
