31,000 scientists reject global warming and say "no convincing evidence" that humans can or will cause global warming? But polls show that of scientists working in the field of climate science, and publishing papers on the topic: 97% of the climate scientists surveyed believe “global average temperatures have increased” during the past century; and 97% think human activity is a significant contributing factor in changing mean global temperatures. What is the significance of these statistics?

40's to 70's cooling, CO2 rising?
-
This is a fascinating denialist argument. If CO2 is rising, as it was in the 40's through the 70's, why would there be cooling?

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.

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.
