The Environment

Evidence of minute amounts of marine life in an ancient Antarctic ice sheet helps explain a longstanding puzzle of why rising carbon dioxide (CO?) levels stalled for hundreds of years as Earth warmed from the last ice age.

Our study shows there was an explosion in productivity of marine life at the surface of the Southern Ocean thousands of years ago. And surprisingly, this marine life once played a part regulating the climate. Hence, this finding has big implications for future climate change projections. Read on.
