In fact, the change in cloud characteristics resulting from this form of air pollution are thought to have asserted a cooling pressure on the earth's surface temperature — a cooling that has acted to offset a certain portion of the warming caused by the co-incidental emissions of carbon dioxide and other greenhouse gases.

However, a new study from a team of researchers led by University of Wisconsin - Madison Space Science and Engineering Center scientist, Claire Pettersen, describes a unique method involving cloud characteristics that could help answer some big questions about the Greenland Ice Sheet and its snowfall.

In this activity students investigate cloud opacity, including transparent, translucent, and opaque cloud characteristics. (nasawavelength.org)
