June Climate Briefing: El Niño Odds Continue Downward Trend

Read our ENSO Essentials & Impacts pages for more about El Niño. Tony Barnston provides an overview of the briefing What’s New Since last month’s briefing, weekly sea-surface temperature anomalies have been similar to the previous month’s temperatures, ranging from +0.4ºC to +0.6ºC in the area of the central equatorial Pacific Ocean that define El Niño and La Niña events, called the […]

Malaria risk increases in Ethiopian highlands as temperatures climb

The highlands of Ethiopia are home to the majority of the country’s population, the cooler climate serving as a natural buffer against malaria transmission. New data now show that increasing temperatures over the past 35 years are eroding this buffer, allowing conditions more favorable for malaria to begin climbing into highland areas. That is the […]

IRI Unveils Its New Generation of Climate Forecasts

This spring, IRI implemented a new methodology for our seasonal temperature and precipitation forecasts around the world. We asked Simon Mason, Andrew Robertson and Tony Barnston, three of our senior climate scientists who lead the development and tailoring of IRI’s forecasts, to answer some fundamental questions about the new forecast. If you use our forecasts […]

May Climate Briefing: El Niño Odds Down Slightly

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 have increased slightly to +0.4ºC to +0.5ºC in the area of the central equatorial Pacific Ocean that define El Niño and La Niña events, called the Nino3.4 region (see first image below). These sea-surface temperatures […]

New paper highlights applications for subseasonal forecasts

A recent study was the first to comprehensively review the potential applications of subseasonal-to-seasonal (S2S) forecasts, and several affiliates of IRI were co-authors. Andrew Robertson, one of the IRI co-authors, said the paper provides a substantial overview of the progress achieved in S2S — i.e. forecasts issued with two-week to two-month lead times — over 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 […]

ENACTS Maprooms for Malaria Control

Climate data and tools for malaria control in Africa – the ENACTS initiative By Madeleine Thomson Public health policy makers and practitioners are increasingly concerned about the  impact that climate, environmental and social changes might have on the effectiveness of current and future vector-borne disease control and elimination programs. Yet, while climate change adaptation programs […]

April Climate Briefing: Models Bullish on El Niño Odds

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 have held steady at +0.2ºC to +0.3ºC in the area of the central equatorial Pacific Ocean that define El Niño and La Niña events, called the Nino3.4 region. While these sea-surface temperatures (SSTs) point to […]

New Climate Data Transforms Insurance Projects in Africa

By Dan Osgood, Lead Scientist, IRI Financial Instruments Sector Team Small farms are vulnerable to climate risk, but most smallholder farmers around the world don’t have access to insurance and other financial tools to manage fluctuations in climate. Over the past decade we’ve put a great deal of effort into a new kind of insurance–index insurance–that […]

World Met Day: Partnering with national meteorological services to support farmers in Africa

The below is an excerpt from a blog written by IRI staff members James Hansen, Alison Rose and Dannie Dinh and originally appearing on the CCAFS website. On World Meteorological Day, we highlight how CCAFS and partners are supporting national meteorological services in African countries to provide actionable local climate information to farmers. The important contributions […]
