Climate change and climate variability have multiple deleterious consequences that affect our daily life. There is an exceptional opportunity of achieving simultaneous and complementary data from a multitude of geoscience and environmental near-earth orbiting artificial satellites to study phenomena related to climate change. These satellite missions provide essential information about the various phenomena, such as cryosphere changes, ice sheet melting, ocean currents, sea-level change, terrestrial water storage changes, atmospheric composition, soil moisture variation, temperature changes, and earth surface deformations.
