The Science of Predicting Fires
By Rebekah Heath On the tails of the destructive California wildfires of this year, the 2017 Conference on Fire Prediction Across Scales is scheduled to take place October 23-25 at Columbia University. Globally, fires play an important role in climate change, as they emit both aerosols and greenhouse gases into the atmosphere at accelerated rates. […]
Tackling Sleeping Sickness in Maasai Communities
Powerful new tool helps rural Tanzanians reduce their exposure to tsetse flies and the deadly disease they carry. Pietro Ceccato remembers his first trip three years ago to a Maasai village located a two hour’s drive south of Arusha, Tanzania. He was there with a team of public health researchers to learn more about the […]

Rising Temperatures Lead to Increased Fire Risk in Indonesia
A new paper published in the journal Environmental Research Letters, shows that rising temperatures have increased the risk of fires even during non-drought years in Indonesia, possibly making mild fire seasons in the country a thing of the past. The study was conducted by scientists at IRI, the International Center for Tropical Agriculture (CIAT), Temple University and the Center for International […]
Heightened Fire Activity Predicted for Amazon in 2016
The IRI has developed a forecast maproom that characterizes the expected fire activity in the Amazon based on climate conditions for the upcoming dry season. Kátia Fernandes, along with Walter Baethgen and Lisa Goddard, have been researching how the Amazon fires are influenced by large-scale ocean phenomena and how sea surface temperature (SST) forecasts can […]
El Niño 2015 Conference Report
In November 2015, the International Research Institute for Climate and Society at Columbia University, in collaboration with the World Meteorological Organization, the U.S. Agency for International Development and the U.S. National Oceanic and Atmospheric Administration, convened the El Niño 2015 Conference. The report from this conference is now available. In addition to recordings and summaries of the […]

The Atlantic Ocean holds the key to western Amazon rainfall
By Samuel McGlennon This post is an excerpt of a piece on the website for the Center for International Forestry Research. View the full article here. In 2010, catastrophic fires ravaged huge tracts of the western Amazon, a region of rainforest that until just a few years earlier was considered beyond the reach of serious drought. Those […]

Study: El Niño’s Impacts on Water, Agriculture and Health
By Ben Orlove and Ángel Muñoz A new study examines the degree to which decision makers working in key sectors–agriculture, water and health–have been able to make successful use of forecasts of El Niño and La Niña. We find that these forecasts have indeed often been put into use, but only when two conditions have been […]

Managing Water in a Dry Land
The Elqui River basin in Chile’s Coquimbo region is one of the driest places on Earth. It receives only about 100 millimeters (4 inches) of rain each year, and most of it during one short rainy season. The rainfall isalso highly variable. In some years, the region will get close to zero rainfall, while in […]

Are We Entering an Age of Mega-Fires?
For millennia, people have set fires to clear land for cultivation, pastures or hunting; so-called slash-and-burn agriculture is still common across much of tropical Africa, Asia and South America. It has been a useful strategy, but it is now becoming problematic. A new Earth Institute story and documentary, shot in the Peruvian Amazon, follows the […]
Climate change threatens a fragile ecosystem in the Andes
In the Andes mountains of Colombia, Ecuador, Peru, and Venezuela, tucked between the tree line and the line of permanent snow, is the páramo, a unique and hauntingly beautiful mountainous wetland that is threatened by climate change and growing temperature extremes. The páramo of the Northern Andes is wet and cold. Temperatures can dip below […]
To Burn, or Not to Burn
Imagine smoke and haze so thick it causes ships to crash into each other, shuts down airports and sends millions of people to the hospital with respiratory problems. This was the scene in Southeast Asia in 1997 and 1998, when land-clearing fires set by massive palm oil plantations and small scale farmers burned out of […]
