The spreading of the seafloor has slowed, and scientists aren’t sure why. The slowdown could mean a drop in greenhouse emissions from volcanoes, which are affected by the seafloor-creating process.

Magma from the mantle meets the ocean at seafloor spreading centres. At young rifts, basalt sills may heat overlying sediments and induce natural carbon release; ...
