Why do we care about El Niño and La Niña?
Scientists have shown that the occurrence of floods, droughts and other climate-related disasters is not statistically different among years with El Niño, neutral or La Niña conditions (see Figure 1). So why does the El Niño-Southern Oscillation, or ENSO, matter? The short answer: in years with El Niño or La Niña conditions, such disasters may be more predictable, allowing decision […]
El Niño Odds Reduced
From the January climate briefing, given by IRI’s Chief Forecaster Tony Barnston: Tony Barnston provides an overview of the briefing Changes from last month’s briefing Based on the latest models, the chance of an El Niño developing during the current (January – March) season is around 63%, down from 76% last month. These odds for the current season are similar to those issued by the NOAA […]
December Climate Briefing: El Limbo Continues
From the December climate briefing, given by IRI’s Chief Forecaster Tony Barnston: Tony Barnston provides an overview of the briefing Changes from last month’s briefing Based on the latest models, the chance of an El Niño developing during the current (December-February) season is over 80%, up slightly from last month. These odds for the current season are also higher than those issued by the NOAA Climate Prediction Center/IRI […]

Getting it Right on Climate Resilience
By Lisa Goddard, IRI Director For many parts of the world, especially in developing countries, no early warning systems exist for storms or floods. No decision-support systems provide regular or timely information for farmers that depend on seasonal rains. The impacts are broad – this century has already seen a million deaths and $1.7 trillion […]
November Climate Briefing: El Limbo
From the November climate briefing, given by IRI’s Chief Forecaster Tony Barnston: Tony Barnston provides an overview of the briefing Changes from last month’s briefing Based on the latest models, the chance of an El Niño developing during the current (November-January) season is about 75%, up slightly from last month. These odds for the November-January season are also higher than those issued by the NOAA Climate Prediction […]
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. This month, students completed the final course in a series of four online courses that address the ongoing societal challenges of managing water resources under the pressures of climate change and variability. Early in 2014, the Water and Climate Education Program […]
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 […]
