In today’s demographically diverse world, population issues abound, creating different and important social, economic, and political implications. World Population Day (observed each year on July 11) offers an opportunity to reflect on why population is so important. Understanding the implications of population growth and decline, as well as population age structure and migration—is essential to strengthen our abilities to plan for a more sustainable future.

Scientists from the National Oceanic and Atmospheric Administration (NOAA) have predicted an El Niño event between late 2023 and early 2024. El Niño is a complex climate phenomenon characterized by unusually warm sea surface temperatures in the central and eastern Pacific Ocean near the equator that typically happens every two to seven years. This phenomenon amplifies the likelihood of severe weather events in specific regions due to changes it creates in atmospheric circulation patterns, which escalate and initiate consequences for the environment, economy, and human health.

In Conflict-Affected Somalia, Climate Change Adds to Migration Pressures

In the Somalian coastal town of Hobyo, thousands of residents—some of whom settled there to flee the country’s civil war—are starting to leave. Why? Their homes are being engulfed by sand.

Climate change is a security concern due to its role as a risk multiplier, aggravating political, social, and economic vulnerabilities, straining resources, and undermining institutions. And as climate change intensifies, its impact on military operations around the world, including UN peacebuilding efforts, will grow in tandem.

Climate Change and Migration: Ensuring Safe Access for Women and Girls

A new report from UN Women found that climate change poses a significant threat gender equality. In particular, changes in weather patterns and extreme events exacerbate vulnerability among women and girls and leads them to seek safety and opportunities through increased migration.

When the National Oceanic and Atmospheric Association (NOAA) declared the beginning of an El Niño event on June 8, 2023, the recurring climate pattern featured in headlines all over the world as media outlets sought to cover its anticipated impacts.

A recent Water @ Wilson event –“The Significance of the Coming El Niño: Understanding the Science and Preparing for its Impacts”—brought together experts at the Wilson Center to explain the complex science behind El Niño and explore its regional implications. The speakers also surveyed the policy tools at our disposal to prepare for its significant climate effects.

When cows eat, they burp. And what they exhale generates almost a third of global methane emissions – a greenhouse gas 80 times more potent in warming the climate than CO2. So tracking this short-lived climate gas is crucial.  

Six miles from Bakersfield, California, at the Bear 5 cow feedlot, this work is starting to happen. High-resolution satellites are being used for the first time at the feedlot to track methane emissions from cow burps. Measuring cow belches from space is bringing critical attention to the brewing climate issues from cows. After all, the methane produced by these gassy animals in one year at Bear 5 cow feedlot alone could power more than 15,000 homes in California.
