In unequal contrast
- By contrast, less than a quarter of the planet's land (22.4%) experienced wetter conditions, with areas in the central United States, Angola’s Atlantic coast, and parts of Southeast Asia showing some gains in moisture.

A permanent problem
- What makes aridity particularly concerning is its permanence. Unlike temporary droughts—periods of insufficient rainfall that can eventually end and allow for recovery—aridity is an ongoing, unyielding condition.

A parched world
- "Unlike droughts—temporary periods of low rainfall—aridity represents a permanent, unrelenting transformation," Thiaw adds. "Droughts end. When an area’s climate becomes drier, however, the ability to return to previous conditions is lost. The drier climates now affecting vast lands across the globe will not return to how they were and this change is redefining life on Earth."

New UN report warns over 75% of Earth's land is now permanently drier
Aridity: The "existential crisis" redefining life on Earth
© Getty Images
Climate crisis campaigners and advocates are likely to echo a resounding "we told you so" in response to the latest findings from the UN Convention to Combat Desertification (UNCCD). The report reveals three-quarters of the Earth's land has become permanently drier over the last three decades. The report, 'The Global Threat of Drying Lands: Regional and Global Aridity Trends and Future Projections,' was launched at the 16th UNCCD conference in Riyadh, Saudi Arabia (COP16) in 2024. This was the largest UN land conference to date and the first to be held in the Middle East—a region heavily impacted by arid conditions, highlighting an unfortunate irony.
