IRI @ AMS: Schedule of Events

“Observations Lead the Way” is the theme for the upcoming 97th annual meeting of the American Meteorological Society. Much, if not all, of the initiatives at the International Research Institute for Climate and Society rely on a critical mass of quality weather and climate observations. The presentations of IRI’s staff and scientists at this year’s […]

December Climate Briefing: La Niña Lingers, Likely to Lapse

Read our ENSO Essentials & Impacts pages for more about El Niño. Tony Barnston provides an overview of the briefing Since last month’s briefing, weekly sea-surface temperature anomalies in the area of the central equatorial Pacific Ocean that define El Niño and La Niña events, called the Nino3.4 region, have remained within a tenth of a degree of the -0.5ºC threshold indicative of La […]

Health and Climate Colloquium Report

Earlier this year, the International Research Institute for Climate and Society and the Mailman School of Public Health, both of Columbia University, hosted the Health and Climate Colloquium 2016. The purpose of the Colloquium was to help build a global community of health practitioners and policymakers that can use climate information as a means to […]

IRI@AGU: Advancing Climate Prediction at New Timescales

Andrew Robertson is a senior research scientist at the International Research Institute for Climate and Society. He heads IRI’s climate group and studies how to improve climate forecasts with lead times between two weeks to two months, referred to by scientists as the subseasonal-to-seasonal (S2S) timescale. He also co-chairs the S2S Prediction Project Steering Group, which […]

IRI@AGU: Upmanu Lall on Improving Risk Management

Upmanu Lall is the director of the Columbia Water Center, a senior research scientist at IRI and the Alan & Carol Silberstein Professor of Engineering in the School of Engineering and Applied Sciences. In addition to other presentations at the 2016 American Geophysical Union Annual Meeting, Lall will be presenting, “Quantifying conditional risks for water and […]

S2S Workshop: Summary Blog

Below is an excerpt from a blog post written by Zane Martin for the Initiative for Extreme Weather and Climate. For the full post, see the Initiative’s site. By Zane Martin Last week hundreds of scientists from around the world attended the Workshop on Sub-seasonal to Seasonal Predictability of Extreme Weather and Climate online and at Columbia University’s […]

IRI@AGU: Schedule of Events 2016

A range of IRI’s areas of expertise will be represented at this year’s annual meeting of the American Geophysical Union (AGU). Many of the presentations center on fundamental climate science, including analyses of the influence of climate variability and change on rainfall in the US, Iran, South America and the Sahel, as well as the […]

Event: S2S Extremes Workshop

This week, the International Research Institute for Climate and Society (IRI), the Extreme Weather & Climate Initiative (Extreme Weather), and the WWRP/WCRP Sub-Seasonal to Seasonal Prediction Project will hold a 2-day workshop at the Columbia University Lamont-Doherty Earth Observatory campus in Palisades, New York. Adam Sobel, one of the co-organizers of the event, said that the workshop will bring […]

November Climate Briefing: La Niña Arrives, Some Impacts Likely

Read our ENSO Essentials & Impacts pages for more about El Niño. Tony Barnston provides an overview of the briefing Since last month’s briefing, sea-surface temperatures in the area of the central equatorial Pacific Ocean that define El Niño and La Niña events, called the Nino3.4 region, have remained cooler-than-average. Since July, weekly sea-surface temperature anomalies have been around or just below the -0.5ºC […]

New Climate Data in Zambia Unlocks Insurance Opportunities

In mid September, IRI staff helped launch an innovative new data platform in Lusaka, Zambia that combines satellite rainfall estimates with the country’s existing network of rain gauges. The platform, developed with the Zambia Meteorological Department and through funding from NASA, is the latest to come out of IRI’s Enhancing National Climate Services (ENACTS) initiative […]
