Key Points

• The dominant signal is a new paleoclimate estimate that tropical land warming can substantially exceed tropical ocean warming under high CO2 conditions.
• The Bogota Basin sediment core is the core evidence base, with multiple outlets describing the same underlying study and methods.
• The Andean tropical highlands stand out as the key region, with reconstructed land warming around 3.7 to 4.8 C above comparison periods depending on the framing used.
• The recurring comparison is land versus sea: land warming is estimated at roughly 1.6 to nearly 2 times the tropical ocean signal.
• The work uses the late Pliocene as a climate analog for future warming because atmospheric CO2 levels were closer to today's than the later Pleistocene.
• A persistent implication is that regional heat and drought stress in tropical mountain regions may be higher than simple global-average expectations suggest.
• The topic is cohesive and research-driven, with little evidence of fragmentation beyond minor differences in how outlets report the temperature figures and proxy methods.
