Tree-Ring Lab (TRL) scientists are dedicated to expanding the use and application of tree-ring research around the world to improve our understanding of past climate and environmental history. Current research concentrates on the use of tree-ring data networks to study regional climate, global climate teleconnections and anthropogenic impacts on forest growth.

Exploring new species in new regions, building collaborations around the world, and developing new quantitative techniques, TRL researchers are committed to advancing dendrochronology and paleoclimatology, as well as the ethic of good science

Naomi Henderson	Research Scientist	Ocean Modeling, Model Data Management
Richard Seager	Palisades Geophysical Institute/Lamont Research Professor	My interests are in climate variability and change on timescales of seasons to millennia and in particular the causes of multiyear droughts around the world and how climate change will impact global hydroclimate. I analyze observations, proxy climate records and model simulations and also use idealized modeling to understand the basic climate dynamic processes in the atmosphere and ocean that generate global climate variability and change.

New Salt Map of the Seas Gives Scientists a Taste of Discoveries Ahead

October 03, 2011

After less than a month in operation, a new NASA satellite has produced the first map showing how saltiness varies across the surface of the world’s oceans. Until now, salt measurements came only from ships, moorings and buoys floating at sea; NASA says its Aquarius satellite will capture in three years as much data as those earlier methods did in 125 years.
Investigating a Tropical Weather Pattern with Global Reach

September 27, 2011

As it moves across the Indian Ocean, the Madden-Julian Oscillation (MJO) can bring torrential rains to California and add power to hurricanes forming in the Gulf of Mexico. Yet after 30 years of studying this cyclical weather pattern scientists are no closer to understanding how it works.
As the Dead Sea Dries, Drilling Shows It's Not the First Time

December 22, 2010

In the first project of its kind, scientists are drilling deep into the bed of the fast-shrinking Dead Sea, searching for clues to past climate changes and other events that may have affected human history back through Biblical times and before.
Tundra, Microbes and World Climate

January 26, 2010

O. Roger Anderson is a microbiologist at Lamont-Doherty Earth Observatory who studies bacteria, amoebas, fungi and other microorganisms. Lately he has been thinking about how tiny organisms that inhabit the vast northern tundra regions could contribute to changing climate, since, like humans, they breathe in oxygen and breathe out carbon dioxide.

Oceans' Uptake of Manmade Carbon May Be Slowing

November 16, 2009

The oceans play a key role in regulating climate, absorbing more than a quarter of the carbon dioxide that humans put into the air. Now, the first year-by-year accounting of this mechanism during the industrial era suggests the oceans are struggling to keep up with rising emissions...
Climate Change Work by Lamont-Doherty Researchers Recognized

April 09, 2009

Four current and former researchers at Lamont-Doherty Earth Observatory will receive honorary degrees from their alma mater, St. Lawrence University, this spring. The degrees will be awarded at May graduation to paleoclimatologist Peter deMenocal; engineer Dale Chayes; paleoceanographer Miriam Katz; and oceanographer Richard Fairbanks.
Lamont Scientist Peter DeMenocal in the 11th Hour

July 15, 2007

July 15, 2007 - The 11th Hour is a 2007 feature film documentary created, produced and narrated by Leonardo DiCaprio on the state of the natural environment.

Lamont’s own Associate Professor Peter deMenocal is one the climate change experts interviewed in the film.
Climate Change — Hollywood Fiction or Reality?

May 26, 2004

Two centuries since the start of the Industrial Revolution, the human population has increased six-fold, and economic activity an estimated fifty-fold. The sheer number of people on the planet and the intensity of economic activity are having profound effects on the long-term global climate, threatening to disrupt vast biological, geochemical, and social systems in future decades. This is fact.
