2015 Colvin Award winner, Kathryn Grabowski ’16, conducting a clipping experiment as part of her senior thesis research in Mozambique during the summer of 2015. The swimming pool at Chitengo Camp is a bright blue circle shaded by trees. It is a tranquil place to relax after a dusty game drive in Gorongosa National Park, but not long ago this inviting oasis was used by rebel forces as a prison. The pool, now ringed with deck chairs, instead of armed guards, is just one small sign of

The oscillations during the past 2.5 million years between ice ages and interglacials were probably triggered by orbital changes, but the observed amplitude and timing of these climate cycles still awaits a full explanation. One notable correlation links lower partial pressure (or concentration) of CO2 with ice ages: changes in CO2 concentration may cause some of the ice-age cooling, but what causes the loss of CO2 is unknown.
