A River Runs Through It: Predicting Floods in the Midwest
Three of North America’s major rivers run through the Midwestern U.S. In the spring of 2011, major flooding in region caused an estimated $3 billion in damages and killed seven people. Although scientists cannot predict exact precipitation amounts for a given season, they can attempt to predict the odds that a given season will have below average, […]
Improving the Water Outlook in the Himalayas
Andrew Robertson, a climate scientist at the International Research Institute for Climate and Society, discusses his research on helping reservoir managers in northern India make better planning decisions by improving their ability to predict how climate change will influence water availability. In order to do this, Robertson worked with colleagues at the Columbia Water Center and the […]
The Truth About Verification
In December 2011, the International Research Institute for Climate and Society issued a seasonal precipitation forecast. The forecast called for a 75 percent chance of above normal precipitation over parts of the Philippines between January and March. As the months played out, storms brought roughly eight inches more rain than usual for the period. That’s about 85 percent […]

Photo Essay: Into the Heart of Dryness
Niger is one of the poorest countries in the world. Life expectancy there is 54 years, and it has an infant mortality rate higher than any other country except Afghanistan. It is also a country that is extremely vulnerable to climate variability and change. The livelihoods of four out of five people in Niger depend […]
Decadal Prediction: The New Kid on the Block
Climate scientists generally group future outlooks of the earth’s climate into two, and now possibly three, time-scales. First, there’s short term, or seasonal forecasting, which covers the next month to a year into the future. The International Research Institute for Climate and Society and other centers in the U.S. and around the world issue new […]
Climate Services: No need to wait for disasters to happen
This is the third of ten interviews with climate and development experts conducted at the International Conference on Climate Services, held at Columbia University in October 2011. Maarten Van Aalst is the Director of the Red Cross/Red Crescent Climate Centre. In this interview he talks about how the Red Cross is using climate information to mobilize […]
Climate Services: A Regional Perspective

Patricia Ramirez is the Director of Meteorology and Climate for the Regional Water Resources Committee, which is based in Costa Rica. She wants to work more with the international […]
A model for improving climate services in Africa
In developed countries, we are accustomed to having access to long and detailed records on weather and climate conditions, demographics, disease incidence and many other types of data. Decision makers use this information for a variety of societal benefits: they spot trends, fine-tune public health systems and optimize crop yields, for example. Researchers use it […]
