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 […]

July Climate Briefing: La Niña Watch Issued

Read our ENSO Essentials & Impacts pages for more about El Niño and La Niña. In mid-July, the sea-surface temperatures were slightly below average but in the ENSO-neutral range, and some atmospheric indicators showed neutral conditions while others leaned slightly toward La Niña. A new set of model runs predicts that cool-neutral or weak La Niña conditions are most likely […]

June Climate Briefing: La Niña Odds Increasing

Read our ENSO Essentials & Impacts pages for more about El Niño and La Niña. By mid-June, the sea surface temperatures had decreased to borderline La Niña levels, while some atmospheric indictors show La Niña-leaning conditions and a few show neutral conditions. A new set of model runs predicts cool-neutral or weak La Niña conditions are most likely from late […]
