Scientists Find the Point of No Return for Antarctic Ice Cap
Varying amounts of glacial debris in a core of ancient sediment show the ice cover grew and shrank until airborne carbon dioxide levels fell below 600 parts per million, spurring steady growth.

Half of Atmospheric Joule Heating Is Due to Small Oscillations
Scientists use sounding rockets to show that small oscillations in electric fields can be just as important for atmospheric Joule heating as the presence of the electric field itself.
