    Laia Andreu-Hayles Explores Tropical Forests in a Warming World

    Research by tree-ring scientist Laia Andreu-Hayles will provide much-needed observational climate data for Bolivia and Peru and insight into the climate sensitivity of tropical tree species in the Andes.

    Park Williams Discovers History and Science in a Tree Ring

    Park Williams studies trees and climate, in particular the causes of drought and the effects of climate change on forests. In this latest in a series of Earth Institute videos, we spoke to him about what he does, what’s important about it, and how his interest in history and environmental science blended into a career.

  • Syria’s Drought Likely Its Most Severe in More than 900 Years

    Syria’s Drought Likely Its Most Severe in More than 900 Years

    “If climate change is having an impact and is making droughts worse, then we should see this in the record over several centuries—and we do,” said the study’s author, Benjamin Cook.

  • A New Global Team Tracks Temperature Change Through Time

    A New Global Team Tracks Temperature Change Through Time

    A new international consortium of scientists is bringing the history of temperature fluctuations across the entire Northern Hemisphere to life.

    Translating Nature’s Historians: The Tree Ring Lab Turns 40

    In its first 40 years, the Lamont Tree Ring Lab tracked changing climates around the world, building an international reputation as a global leader in research, training and technology.

  • Tree Rings on Hawai’i Could Hold New Knowledge About El Niño

    Tree Rings on Hawai’i Could Hold New Knowledge About El Niño

    Annual tree rings are a rare find in the tropical islands of the eastern Pacific. The new discovery of trees with annual rings on a Hawaiian volcano could provide new climate data from a part of the world where much of the variability of the El Niño-Southern Oscillation originates.

  • World Trade Center Ship Traced to Colonial-Era Philadelphia

    World Trade Center Ship Traced to Colonial-Era Philadelphia

    Four years ago this month, archeologists monitoring the excavation of the former World Trade Center site uncovered a ghostly surprise: the bones of an ancient sailing ship. In a new study, scientists at Lamont-Doherty Earth Observatory say that an old growth forest in the Philadelphia area supplied the white oak used in the ship’s frame,…

  • The Pluvial Continues… Has the Long Rain Epoch Begun?

    The Pluvial Continues… Has the Long Rain Epoch Begun?

    Daily comparisons on TV or other media sources are typically based upon recent climate and ignore the past. Dased upon paleo records, the full picture indicates that we are sitting in one of the more unusually wet periods of the last 500 years.
