A prudent planetary limit for geologic carbon storage.

Geologically storing carbon is a key strategy for abating emissions from fossil fuels and durably removing carbon dioxide (CO) from the atmosphere. However, the storage potential is not unlimited. Here we establish a prudent planetary limit of around 1,460 (1,290-2,710) Gt of CO storage through a risk-based, spatially explicit analysis of carbon storage in sedimentary basins.

Ocean plates conductively cool and subside with seafloor age. Plate thickening with age is also predicted, and hot spots may cause thinning. However, both are debated and depend on the way the plate is defined.

The importance of rift history for volcanic margin formation.

Rifting and magmatism are fundamental geological processes that shape the surface of our planet. A relationship between the two is widely acknowledged but its precise nature has eluded geoscientists and remained controversial. Largely on the basis of detailed observations from the North Atlantic Ocean, mantle temperature was identified as the primary factor controlling magmatic production, with most authors seeking to explain observed variations in volcanic activity at rifted margins in terms of the mantle temperature at the time of break-up.
