New Model Helps in Fight Against Deadly Parasitic Disease

IRI scientists and colleagues from South Africa are using satellites to detect seasonal water bodies that harbor schistosomiasis, the deadliest of the tropical neglected diseases Cole Porter romanticized the phrase in his 1936 song, but the probable origin of having someone — or something — under one’s skin is much less pleasant to consider. An […]

Climate Models and Food Security in the Philippines

By Megan Helseth The Bicol River Basin in the eastern Philippines is home to more than 5 million people, most of whom rely on agriculture and fishing for their livelihoods. The area is vulnerable to many climate and weather events, including typhoons, floods and dry spells. Each of these can have major impacts on local […]

Climate Resilience (Animation)

Climate resilience: it’s the ability for communities to recover from the impacts of climate events. It’s the difference between weather being manageable…or a catastrophe. But for many parts of the world, where livelihoods depend so much on the climate, critical weather and climate information is unavailable or unusable. The International Research Institute for Climate and […]

El Niño Drives Drought in the Philippines

A strong El Niño event is in place in the tropical Pacific. IRI’s seasonal forecast for the October-December 2015 period, based on the most recent sea surface temperature projections, predicts a strong likelihood of below-average precipitation for regions in the western equatorial Pacific, including much of the Philippines. The strong likelihood of reduced rainfall during […]

One Size Fits None: Drought forecasting in the Caribbean

This post contains excerpts from the full version on our Medium account.  Most extreme climate and weather events involve an unwanted surplus — too much rain, too much wind or too much snow and ice. Drought is a little different: it’s the absence of something. It takes time for a drought to build, making it fundamentally different to monitor […]

#WorldMetDay: Climate Knowledge for Climate Action

Today is World Meteorological Day, this year themed Climate Knowledge for Climate Action. Since this is basically the name of our game here at the International Research Institute for Climate and Society, we thought we’d share some of our recent, related activities. Working with the World Meteorological Organization Earlier this month, Rupa Kumar Kolli, Chief of the World […]

Video: Managing Water in a Dry Land

The Elqui River valley lies in Chile’s northern, mountainous Coquimbo region, which is extremely dry. The region receives only about 100 millimeters (4 inches) of rain each year, and most of it during one short rainy season. The rainfall is also highly variable and driven in large part on El Niño and La Niña fluctuations. In some years, […]

Looking back: A year of forecasts, partnerships and climate information

by Manon Verchot In 2013, the International Research Institute for Climate and Society teamed up with the University of Arizona to help regions of the world that are most vulnerable to climate variability and change. Here’s a look at what has been accomplished so far. Farmers are at the mercy of the weather. They need […]

IRI’s Role in South Africa’s Seasonal Climate Forecast Operations

Several decades of climate research have shown seasonal temperature and rainfall patterns over southern Africa to be predictable months in advance. While scientists recognized the importance of the El Niño Southern Oscillation on seasonal climate variability in this region during the 1980s, South Africa first began issuing regular seasonal forecasts in the early 1990s. Over the past twenty years, enhanced modeling systems have […]

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 […]

Live from Kingston: It’s CariCOF

By Elisabeth Gawthrop and Mea Halperin The Caribbean Climate Outlook Forum (CariCOF) took place yesterday in Kingston, Jamaica. It is one of a number of Climate Outlook Forums (COFs) around the world during which scientists present a forecast to decision makers who work in climate-sensitive sectors such as agriculture, water management, disaster planning and health. The forecast […]

Q&A – Why care about CariCOF?

Next week, the Caribbean Climate Outlook Forum (known as CariCOF) will kick off in Kingston, Jamaica. At this event, both providers and users of climate information from across the Caribbean will discuss the upcoming season’s forecast and the ways the forecast might be used to make decisions in water resources, tourism and disaster risk management. To learn […]

Water and Climate Courses in the Caribbean

This article is a modification from a post by the Columbia Center for New Media Teaching and Learning. In the Caribbean, most states rely on a single source of water for all domestic, agricultural and industrial needs. Variations in rainfall brought on by climate change add to the challenge of managing this limited resource. Furthermore, there […]

This post is the last in a series of five Q&As with scientists from the International Research Institute for Climate and Society who will be presenting their work at the annual meeting of the American Geophysical Union in San Francisco December 9 to 13. Not all climate forecasts are created (and researched) equally, something that climate scientists […]

Singing the Blues About Water Scarcity

A version of this post originally appeared on the Climate and Society Hot Topics blog. Otis Redding wraps up his acclaimed 1965 album Otis Blue with “You Don’t Miss Your Water.” The refrain “you don’t miss your water ’til your well runs dry” was originally written by William Bell and inspired by his feelings of homesickness for his native Memphis […]

In order to do this, Robertson worked with colleagues at the Columbia Water Center and the […]

The Role of Drought in the Horn of Africa Famine

Let’s get this out of the way. The current famine in the Horn of Africa isn’t caused by drought. Rather, a complex mix of societal and political factors created a dangerous situation.The worst drought in 60 years is what pushed that situation over the edge into a humanitarian crisis. However, just as these social factors were […]
