When most people think about global warming, they envision rising temperatures and sea levels. Robert Agnew, a professor of sociology at Emory, thinks about rising crime rates.

Although people are quite aware of global warming, their beliefs about it may be malleable; specifically, their beliefs may be constructed in response to questions about global warming. Beliefs may reflect irrelevant but salient information, such as the current day’s temperature.

BEST researchers compiled thousands of data sets on temperature anomalies over the course of two centuries into one alarming video of a warming world.

This dataset shows how the global ocean's surface water temperatures vary over the course of few years. In addition to seeing the effects of the seasonal cycle, the viewer can see how surface ocean currents and eddies transport heat and water around the globe. The images were generated not from observations, but from a state-of-the-art computer model of Earth's climate created at NOAA's Geophysical Fluid Dynamics Laboratory (GFDL).

What is the temperature of outer space? way out there between galaxies ... where there is only about one hydrogen atom per cubic meter? Can an individual atom be hot or cold? Can it even have a temperature? It sounds a little silly to say an atom is 27 degrees Fahrenheit or something.
