Columbia scientists recently visited the Caribbean island of Barbados, whose fossilized coral reefs contain an exquisite record of how the ocean has risen and fallen in the past.

Sediments deposited over thousands of years provide a window to the past—and may perhaps shed light on what happened to the island’s now-lost civilization.

Climate scientist Radley Horton is bringing the effects of sea level rise to the attention of decision-makers and fostering discussions to help society confront climate change.

An international collaboration will study the wasting of the Thwaites glacier, which already accounts for around 4 percent of current global sea-level rise, and could collapse within decades or centuries.

Polar scientists Marco Tedesco and Robin Bell provide a primer on how climate change will impact our coastlines.

For decades, scientists believed that the Greenland Ice Sheet is relatively stable compared with the vulnerable West Antarctic Ice Sheet. Two Lamont scientists questioned this assumption about Greenland’s ice and wanted to take a much closer look.

Two new papers find that the line that divides the moist East and arid West is edging eastward due to climate change—and the implications for farming and other pursuits could be huge.
