Scientists originally thought the climate pattern began 22-25 million years ago as a result of the uplift of the Tibetan Plateau and the Himalaya Mountains. But UA researchers say that’s not going back far enough.
The Asian monsoon already existed 40 million years ago during a period of high atmospheric carbon dioxide and warmer temperatures, reports an international research team led by a University of Arizona geoscientist. (more…)

Antarctica’s topography began changing from flat to fjord-filled starting about 34 million years ago, according to a new report from a University of Arizona-led team of geoscientists.
Knowing when Antarctica’s topography started shifting from a flat landscape to one with glaciers, fjords and mountains is important for modeling how the Antarctic ice sheet affects global climate and sea-level rise. (more…)
Renowned geoscientist Richard Alley shares climate history, predictions
About the video: Ice sheet expert Richard Alley told a UD audience about the past and future of Earth’s changing climate when he spoke as part of the DENIN Dialogue Lecture Series.
Richard Alley, Evan Pugh Professor of Geosciences at Pennsylvania State University, appeared at the University of Delaware’s Mitchell Hall on Nov. 8 to discuss his breakthrough findings about abrupt climate changes in Earth’s past and the implications of his research for Earth’s future. (more…)
