SE Asian Sea Levels Were 3-4 Meters Higher Than Today 7-4 Thousand Years Ago

Comprehensive data analysis shows relative sea levels were anywhere from 1 to 7 meters (~3.9 m) higher than present throughout the Mid-Holocene at 15 of 16 assessed sites across Southeast Asia.

A new study (Li et al., 2023) compiles highstand records from sites spanning Thailand, Vietnam, Singapore, Malaysia, Borneo, Sunda Shelf, Makassar Strait…and indicates that throughout southeast Asia there was a “peak RSL [relative sea level] highstand of ~3.9 ±1.1 m at ~6 ka BP or later.”

Of the 16 locations assessed, just 1 did not indicate sea levels were higher than present back when CO2 levels were alleged to be 265 ppm.
