Unrelenting rains led to a miserable famine in Europe from 1315-1317. Just how wet was it? A new study reveals that the beginning of the famine included some of the wettest years in the last 700 years.

Compound risk — when multiple risks occur simultaneously, or one after another — was the topic of a recent discussion as part of the Resilience Media Project, a part of the Initiative on Communication and Sustainability at the Earth Institute.

Park Williams and Richard Seager, climate experts at Lamont-Doherty Earth Observatory, discuss why California wildfires are expected to expand and intensify with climate change.

The changes could affect health, agriculture and ecosystems, the study suggests.

In an unusual new study, scientists say they have detected a growing fingerprint of human-driven global warming on global drought conditions starting as far back as 1900.

A new book, the second in a series of primers with the Earth Institute imprint, provides an interdisciplinary overview drought, bringing together many fields including climate science, hydrology and ecology.

A recent study is the first to show that pollutants and greenhouse gas emissions have directly affected the 20th century evolution of rainfall over a region.

A 19-year drought in the American West is one of the most severe in the past 1200 years—and climate change is partially to blame, according to new research.

The American Geophysical Union fall meeting takes place Dec. 10-14 in Washington, D.C. Here is a guide to key talks and other events from Columbia’s Earth Institute.

Park Williams, a bioclimatologist at Lamont-Doherty Earth Observatory, has found that rising temperatures influence wildfires in the American West.
