Briefings

A University of Massachusetts Amherst-led team discovered that weaker mountain rock erodes three times faster than harder rock, even on gentler slopes. This finding challenges existing models linking erosion to carbon dioxide release, suggesting atmospheric scientists may underestimate CO2 emissions from Earth's rocky surfaces.

Key points

• Weaker rock erodes three times faster than harder rock on gentler slopes.
• Current models underestimate CO2 emissions from rocky mountain surfaces.

Context

This research challenges established geological and atmospheric models regarding erosion and carbon release, potentially altering climate projections.

Limitations

Evidence is limited to a single study from 2026; specific locations, rock types, and measurement units are not detailed in the provided text.
