For many of us, climate change still seems like a vague threat, happening sometime in the future in some distant land. But small island nations are already feeling the brunt of the changing climate.

A new study co-authored by Columbia scientist Francesco Muschitiello suggests we may be underestimating the chances of extreme heat and droughts in Europe under climate change.

For decades, scientists believed the Greenland Ice Sheet to be relatively stable compared with the vulnerable West Antarctic Ice Sheet. But new research by Columbia scientists Gisela Winckler and Joerg Schaefer revealed the ice sheet may be highly unstable.

The World Meteorological Organization’s Commission on Climatology recognizes a Columbia climate forecaster’s scientific contributions.

Marco Tedesco and Robin Bell, polar scientists at Columbia's Lamont-Doherty Earth Observatory polar scientists, provide a primer for non-scientists on the study of climate change as it relates to sea level changes.
