Jacqueline Sentiner

Jacqueline Sentiner is the Hourglass Climate speaker in An "antacid" to fight climate change explaining why olivine matters for Ocean Alkalinity Enhancement. She describes olivine as a natural silicate mineral and says that when it dissolves in seawater it can convert CO2 into bicarbonate.

Her role in the source is to supply the accessible chemistry behind Olivine Carbon Removal. The episode then pairs that explanation with Adam Subhas’s caution that the field still has unresolved scale, speed, tradeoff, and marine-ecosystem questions.
