Executive Summary
Sediment records from Colombia show tropical land warmed nearly twice as much as nearby oceans in past warm periods, raising regional heat risk
- A 580 meter sediment core from Colombia's Bogota basin preserved a rare land climate record
- Researchers reconstructed temperatures from the late Pliocene into the Pleistocene using bacterial lipid proxies
- Tropical Andean land was about 3.7 C warmer than today during the warm period studied
- Nearby tropical sea surface temperatures were about 1.9 C warmer than today
- The land warming was roughly 1.6 to nearly 2 times greater than ocean warming
- Scientists said near permanent El Nino conditions likely intensified warming in the tropical Andes
- The findings suggest tropical land regions could face stronger future heat and drought stress
Quick Facts
- What: Reconstructed amplified tropical land warming from sediment cores
- Where: Bogota basin in Colombia and the tropical Andes
- Why: To understand how tropical land may respond to future warming
- Who: CU Boulder and Brown University researchers
- When: From the late Pliocene into the Pleistocene
