摘要

An ecosystemmodel,NORWECOM.E2E including a module for the carbonate system, has been used to investigate the effects of rising atmospheric CO_2 and climate change on the ocean's acid-base state in the Nordic and Barents Seas. Using the 20C3Mcontrol run and the A1B emission scenario, a downscaling of the GISS-AOMglobal climate model has been used to force the ecosystem model for a reference (1981-2000) and a future climate (2046-2065) simulation respectively. The simulations demonstrate howthe saturation state of seawater with respect to aragonite will evolve, with a shoaling of the saturation horizon of approximately 1200 m in the Nordic Seas, and a large increase in area extent of under saturated surfacewaters. The simulated pHchange in the surface water is?0.19 from 2000 to 2065, while the model estimates an almost doubling of the CO_2 air-sea flux in the Barents Sea increasing the uptake from 23 to 37 gC m~(?2) yr~(?1). The main driver for the modelled changes in surface fCO_2 is the change in DIC, with only minor contributions from temperature, salinity and total alkalinity.

7. The oceans mediate the response of global climate to natural and anthropogenic forcings. Yet for the past 2,000 years — a key interval for understanding the present and future climate response to these forcings — global sea surface temperature changes and the underlying driving mechanisms are poorly constrained. Here we present a global synthesis of sea surface temperatures for the Common Era (ce) derived from 57 individual marine reconstructions that meet strict quality control criteria. We observe a cooling trend from 1 to 1800 ce that is robust against explicit tests for potential biases in the reconstructions. Between 801 and 1800 ce, the surface cooling trend is qualitatively consistent with an independent synthesis of terrestrial temperature reconstructions, and with a sea surface temperature composite derived from an ensemble of climate model simulations using best estimates of past external radiative forcings. Climate simulations using single and cumulative forcings suggest that the ocean surface cooling trend from 801 to 1800 ce is not primarily a response to orbital forcing but arises from a high frequency of explosive volcanism. Our results show that repeated clusters of volcanic eruptions can induce a net negative radiative forcing that results in a centennial and global scale cooling trend via a decline in mixed-layer oceanic heat content.
