Short-lived halogens are produced naturally by phytoplankton and algae found in the oceans.
Its major constituents are chlorine, bromine or iodine. Its life span is less than six months.
According to a recent study, the oceans contribute 8-10% to the cooling of the planet by emitting short-lived halogens.
However, short-lived halogens have a different effect on methane. They increase the lifetime of methane in the atmosphere by dilapidated hydroxyl radicals.
