Using old tree rings and archival documents, historians and climate scientists have detailed an extreme cold period in Scotland in the 1690s that caused immense suffering. It may have lessons for Brexit-era politics.
To help predict the future of sea level rise, scientists from Columbia University’s Lamont-Doherty Earth Observatory are studying ancient corals on the island of Barbados.
Coastal waters play an important role in the carbon cycle by absorbing carbon into sediments or transferring it to the open ocean, a new study co-authored by Columbia geochemist Wade McGillis confirms.
A new study has shown that some of Greenland’s meltwater is actually being soaked into porous subsurface ice and held there, at least temporarily. The research could alter calculations of how ongoing melting might fuel global sea-level rise.
In a remote region around Kenya’s Lake Turkana, Columbia’s Kevin Uno collects fossils and sediments, searching for evidence about past climate, vegetation, animals, and water. His goal: to understand how climate affected our ancestors millions of years ago.
