Scientists have uncovered new evidence from one of Earth’s most extreme ancient warming events, revealing how the climate may recover long after human-driven CO₂ emissions cease.

New study shows that under low warming, planting trees increases global water inequality; under high warming, it reduces overall water availability.

Denmark is investing heavily in restoring carbon-rich agricultural soils as wetlands to reduce greenhouse gas emissions. However, new research from Aarhus University shows that financial compensation alone is not enough to persuade landowners to participate.

Based on in-depth interviews with Danish farmers and landowners, the study highlights that decisions are shaped not only by economics, but also by identity, responsibility, uncertainty, and a deep attachment to the land. Farming practices are closely tied to values about what it means to be a “good farmer,” and these social norms can make it difficult to accept land-use changes such as rewetting fields.

The findings underline that successful climate policies must go beyond financial incentives and address the social and cultural dimensions of land management.
