Short summary
The radiocarbon (14C) levels of a stalagmite (grown 27–11 kyr before today) from Socotra Island (Arabian Sea) show drastic changes across the last termination. Our study highlights the influence of a warming climate with increasing precipitation towards the ending glacial on stalagmite 14C. High-resolution measurements suggest 14C is linked to a denser vegetation coverage on the island. Therefore, stalagmite 14C can be used as a climate tracer on millennial to sub-centennial timescales.
