  • The Indian Ocean has undergone substantial heat and freshwater changes. This Review uses various data sources to examine the causes of contemporary and longer-term hydrological changes, revealing that trends over the twentieth century are linked to anthropogenic forcing, but that those since 1980 are related to the Interdecadal Pacific oscillation.

  • The magmatic processes required to form economic-grade porphyry Cu deposits are still poorly understood. This Review discusses the magmatic, redox and hydrothermal processes required for porphyry ore formation, revealing that both crustal thickness and depth of ore body emplacement can influence metal endowment.
