East African Rift study unveils why breaking up is hard for some continents
Overview: A new look at how continents fracture The East African Rift is more than a dramatic valley and a window into Africa’s geologic future. It has become a natural laboratory for scientists seeking to understand a long-standing question: why do some parts of Earth’s crust resist tearing apart, while others yield and separate? A…

East African Rift Study Explains Why Continents Break
Introduction: A New Layer to an Old Puzzle In a groundbreaking collaboration, Tulane University researchers joined forces with an international team of scientists to revisit the forces that govern how continents split. Their findings challenge long-held assumptions about continental breakup by showing that certain patches of Earth’s crust stay unusually strong while adjacent regions yield…

North American Ice Sheets Triggered Most Sea-Level Rise Before 8,000–9,000 Years Ago
New Evidence Reframes the End of the Last Ice Age Groundbreaking findings published in Nature Geoscience reveal that melting ice sheets in North America played a far larger role in global sea-level rise during the final stages of the last ice age than previously thought. By examining ancient sediments and integrating a global data set,…

North American Ice Sheets Triggered Most of the End-Ice-Age Sea-Level Rise, Study Finds
Breakthrough reshapes our view of last‑ice‑age sea level A Tulane University-led study has overturned long‑standing assumptions about the forces behind the dramatic global sea‑level rise that marked the end of the last ice age. The research, published in Nature Geoscience, finds that melting ice sheets in North America contributed far more to sea‑level rise between…
