Growing Glaciers in a 'Supergreenhouse'
New research indicates glacial ice existed on Earth during intense period of global warming
Researchers at Scripps Institution of Oceanography at UC San
Diego are digging deep beneath the ocean floor to study a
global warming event that took place on Earth nearly 91
million years ago. This extreme warming event in Earth's
history raised tropical ocean temperatures about 10°C (18°
F) higher than exist today, thus creating an intense
"supergreenhouse" climate. Despite these extremely warm
conditions, new research suggests that large glacial ice
sheets existed and were able to grow.
