Paleo-perspectives on ocean acidification.
The anthropogenic rise in atmospheric CO(2) is driving fundamental and unprecedented changes in the chemistry of the oceans. This has led to changes in the physiology of a wide variety of marine organisms and, consequently, the ecology of the ocean. This review explores recent advances in our understanding of ocean acidification with a particular emphasis on past changes to ocean chemistry and ...
متن کاملA Paleo Perspective on the Ocean’s Role in the Carbon Cycle
Recently developed proxies for the seawater carbonate ion concentration were used to reconstruct the vertical gradient in the carbonate ion concentration for times in the past corresponding to the glacialinterglacial cycles. The reconstructed changes leave little doubt that the ocean drove the large natural variations in atmospheric carbon dioxide that accompanied the glacial cycles, most likel...
متن کاملAccelerated warming of the Southern Ocean and its impacts on the hydrological cycle and sea ice.
The observed sea surface temperature in the Southern Ocean shows a substantial warming trend for the second half of the 20th century. Associated with the warming, there has been an enhanced atmospheric hydrological cycle in the Southern Ocean that results in an increase of the Antarctic sea ice for the past three decades through the reduced upward ocean heat transport and increased snowfall. Th...
متن کاملHydrological Cycle And
The atmospheric hydrological cycle is compared for diierent time slices of the late Quaternary. Simulations have been conducted with an atmospheric circulation model at T42 resolution, and we have performed a global evaluation of the atmospheric water vapor transport. The water export from the Atlantic catchment area, important for driving the large-scale thermohaline ocean circulation, is anal...
متن کاملAerosols, climate, and the hydrological cycle.
Human activities are releasing tiny particles (aerosols) into the atmosphere. These human-made aerosols enhance scattering and absorption of solar radiation. They also produce brighter clouds that are less efficient at releasing precipitation. These in turn lead to large reductions in the amount of solar irradiance reaching Earth's surface, a corresponding increase in solar heating of the atmos...
