New 'in and out' mechanism reveals how carbon dioxide reacts at water's surface

Each year, billions upon billions of tons of CO2 are pumped into the atmosphere. A significant proportion of this ends up in Earth's oceans, where it can react with water to form carbonic acid, which causes ocean acidification.
