摘要

Climate modellers in Brazil are getting ready to unleash a silicon god. Named Tupa, after a native South American god of thunder, a Cray XT6 supercomputer is gradually coming to life at Brazil's Centre for Weather Forecast and Climate Studies in Cachoeira Paulista, northeast of Sao Paulo. By late November, when the machine is expected to be fully operational, it will have a peak processing speed of more than 244 teraflops, ranking it among the top 25 most powerful computers in the world. So great is Tupas thirst for electricity that it will only run at 20% capacity until a new power source comes online in February 2011.

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.
