ENACTS Climate Services Initiative Ripples Across East Africa with WISER Support

Somalia, South Sudan and a number of other East African countries are now developing their own powerful climate analysis and visualization tools for decision making, using the Enhancing National Climate Services (ENACTS) approach. These efforts were made possible through a partnership with the Kenya-based IGAD Climate Prediction and Application Center (ICPAC) and with funding from […]

October Climate Briefing: La Niña Comes Knocking

Read our ENSO Essentials & Impacts pages for more about El Niño and La Niña. In mid-October, the tropical Pacific sea-surface temperatures were well below average and into the moderate strength La Niña range. All atmospheric parameters also indicated La Niña conditions. A new set of model runs predicts moderate or possibly strong La Niña conditions through 2020 and most […]

New data and tools bring a deeper understanding of El Niño

Updated maps document expected impacts of ENSO conditions for decision makers across the globe. In 2001, the International Research Institute for Climate and Society’s Simon Mason and Lisa Goddard published an important analysis of how El Niño and La Niña events historically have influenced rainfall around the world. Out of that analysis they produced a […]

Student Spotlight: Finding ways for climate services to improve nutrition in Vietnam

By Joseph Conway During the summer of 2019, Pranav Singh, a graduate student at Columbia University’s School of International and Public Affairs, interned in Hanoi, Vietnam for the Adapting Agriculture to Climate Today, for Tomorrow (ACToday) Columbia World Project. Singh’s work focused on understanding where climate services–weather forecasts, early-warning systems, climate predictions and other resources–could […]

September Climate Briefing: La Niña Eminent

Read our ENSO Essentials & Impacts pages for more about El Niño and La Niña. In mid-September, the tropical Pacific sea surface temperatures were below average and into the weak/moderate La Niña range. Most atmospheric indicators also suggested La Niña conditions. A new set of model runs predicts likely weak or moderate La Nina through fall and most of winter, […]

Researchers Show Potential for Subseasonal Forecasts to Predict Dengue Outbreaks

A new study demonstrates for the first time that subseasonal rainfall and temperature forecasts can be used to predict outbreaks of dengue fever by estimating mosquito abundance. Climate models are often applied to future predictions, but one of the most reliable ways to improve and test the capabilities of these models is to look to […]

August Climate Briefing: La Niña Seeming More Likely

Read our ENSO Essentials & Impacts pages for more about El Niño and La Niña. In mid-August, the tropical Pacific sea-surface temperatures were below average, near the threshold for weak La Niña conditions. Some atmospheric indicators showed neutral conditions while others leaned toward La Niña. A new set of model runs predicts that weak La Niña conditions are most likely […]

Study Quantifies Potential COVID-19 Spread From Hurricane Evacuation

With the peak of the hurricane season coming up and COVID-19 abundant in many hurricane-prone areas, the United States is poised to experience the collision of two major disasters. According to a study by scientists at Columbia University and the Union of Concerned Scientists (UCS), a large-scale hurricane evacuation would increase COVID-19 cases in both […]
