In brief
The U.N. warns that persistent dryness now affects over 75% of Earth’s land, increasing the risk of ecological crises.
According to a recent report from the United Nations, a staggering three-quarters of the Earth’s land has become increasingly arid in recent decades, signaling a "global, existential peril." The report attributes this drastic change primarily to human-induced climate change—specifically, industrial emissions of greenhouse gases. The findings emerged as leaders gathered for a U.N. summit in Riyadh, Saudi Arabia, focused on combating desertification and its extensive ramifications for the planet. The report reveals that nearly one in three people now live in moisture-limited regions—up from one in five in 1990. Key agricultural areas, such as Argentina, Spain, and the Black Sea region, are among the hardest hit. Narcisa Pricope, a land systems scientist from Mississippi State University and one of the report's authors, warns that the deterioration is not a distant issue but an ongoing crisis that will impact future generations. Climate-related challenges like sand and dust storms, wildfires, and crop failures are likely to intensify unless nations take proactive measures to curb rising temperatures. Areas already experiencing water scarcity, like South Sudan, are at risk of further instability and conflict. Dr. Pricope emphasized that these developments are unfolding before our eyes, affecting the lives of children today.
