TL;DR: It is shown that both acidification and warming cause a parabolic response in the calcification rate within this coral species, suggesting that ocean warming poses a more immediate threat than acidification for this important coral species.

TL;DR: Anthropogenic elevation of atmospheric CO2 is driving global-scale ocean acidification, which consequently influences calcification rates of many marine invertebrates and potentially alters their s....

TL;DR: In this article, the authors investigated the effects of seawater saturation state (ΩA = 0.4-4.6) and temperature (10, 25°C) on gross rates of whole-shell dissolution for ten species of benthic marine calcifiers: the oyster Crassostrea virginica, the ivory barnacle Balanus eburneus, the blue mussel Mytilus edulis, the conch Strombus alatus, the tropical coral Siderastrea siderea, the temperate coral Oculina arbuscul

TL;DR: The experiments reveal that calcification rates decreased for urchins reared under elevated p CO 2, with the decline being more pronounced under wintertime temperatures than under summertime temperatures, and suggest that impact of CO 2 -induced ocean acidification on urchin calcification will be more severe in the winter and in cooler waters.

TL;DR: It is shown that massive calcareous reefs, built slowly by the alga Clathromorphum nereostratum over centuries to millennia, are now declining because of the emerging interplay between these two processes, and the effects caused by the absence of this predator can be further exacerbated by climate warming.
