Every summer, some of the ice that covers the Arctic Ocean melts. Come mid-September, it begins to refreeze. Scientists began to monitor this cycle in the late 1970s, and this year, they saw less ice than ever before - a lot less ice. NPR science correspondent Richard Harris joins us here in Studio 3A. Richard, nice to have you on the program.

I would like to give you this. It's not much. But in its way it may offer some solace on this date always synonymous with suffering.
It's an image. It is a picture of someplace else, someplace utterly different, someplace that knows nothing of the hatred, bigotry and violence humans unleash on each other for the most seemly absurd reasons.
It's human nature to hope for positive results after spending months or even years conducting a research study. In well-designed studies, however, scientists identify in advance the criteria for success, so their optimism won't color their conclusions when the study is completed.
Our solar system has a pleasing architecture. There are four inner rocky, or "terrestrial", planets on tight, closely spaced orbits. Then comes the asteroid belt. After that comes four outer gas/ice giants on much more widely space orbits.
