As researchers investigate the connection between climate change and conflict, the relative power of communities and individuals attempting to cope with climate change has become a recurring theme. While climate change may not directly cause conflict, it may be inextricably woven into pre-existing conflicts of power, ethnicity, and economic interest.

Contrary to popular belief, Lake Chad is not shrinking, according to Shoring up Stability: Addressing Climate and Fragility Risks in the Lake Chad Region, a new report from adelphi. This finding has profound implications for how the governments of countries bordering Lake Chad (Nigeria, Niger, Chad, and Cameroon) as well as the international community should address the conflict trap in which the people of the region are caught. “Supporting the people of the basin,” write the authors, “is not a function of saving Lake Chad from desiccation.” 

In parts of the tropics, exposure to extreme temperature or rainfall in early life is associated with fewer years of schooling in later childhood. This finding comes from my new article in the Proceedings of the National Academy of Sciences, with coauthor Clark Gray. As climate change leads to increasingly severe heat waves, floods, droughts, and hurricanes, it is important to understand how extreme weather impacts kids’ education in different parts of the world. This will help decisionmakers develop solutions to keep children in school in a world of increasing climate variability.

As Arctic ice melts, we can physically see glaciers retreating. But what we can’t yet see is the exact effect climate change will have on the environment, humans, economies, and national security. Less ice for longer periods each year will likely bring opportunities and related challenges as Arctic and non-Arctic states jockey for position.

“When states face fragility and climate risks simultaneously, the risks and challenges are compounded,” according to The Intersection of Global Fragility and Climate Risks, a new global report commissioned by USAID, which was presented during a recent USAID Adaptation Community Meeting webcast. States facing major climate hazards, such as flooding, drought, and sea level rise, will be forced to contend with the cost of humanitarian and adaptation responses to mitigate the physical and livelihood risks threatening their populations. Fragile states struggling with issues of legitimacy in the social, economic, political, and security spheres may become overwhelmed by the process and cost of redirecting limited resources to address climate-induced disasters.  

The Paris Agreement in December 2015 set targets to limit global climate change. To prevent average global temperatures from rising 2°C above preindustrial levels, it recommends limiting the temperature increase to 1.5°C above preindustrial levels. “But the Paris Agreement is only a half-deal; it will not alone save the diversity of life on Earth or conserve ecosystem services upon which humanity depends,” say the authors of a new article published in Science Advances. Their article proposes a Global Deal for Nature (GDN), a time-bound, science-driven plan to save the diversity and abundance of life on Earth.  

“Food production is the largest consumer of water and also represents the largest unknown factor of future water use as the world’s population continues to balloon, and we face increasing weather-related shocks and stresses,” said Laura Schulz, Acting Deputy Assistant Administrator in USAID’s Bureau for Economic Growth, Education and Environment. She spoke at “Feeding a Thirsty World: Harnessing the Connections Between Food and Water Security,” an event sponsored by the Wilson Center, Winrock International, the Sustainable Water Partnership, and USAID. Currently about 70 percent of global water goes to agriculture, a number that is projected to rise “as high as 92 percent,” said Rodney Ferguson, the President and CEO of Winrock International. 

In 2018, California experienced its most destructive wildfires in history. Satellite imagery shared by NASA scientists helped firefighters track fires and map damage by comparing satellite images documenting changes to the Earth’s surface. These types of images existed for decades but were classified for military purposes until the government program MEDEA identified their potential benefit and advocated for public access in the 1990s. According to former National Oceanic and Atmospheric Association (NOAA) Chief Scientist and MEDEA member Richard Spinrad, “the systems that might be used for early detection of a missile launch may work equally well for detection of wildfires.”
