摘要

The nature of the interactions between climate and tectonic processes is strongly debated. It has been proposed that a shift towards a cooler and more erosive climate would enhance topographic relief in mountain ranges. The isostatic response to this change in relief (whereby parts of the Earth's lithosphere rise if material is removed and sink if it is deposited) could raise mountain crests even higher, driving climate to an even more erosive state and forming a positive feedback loop. On page 39 of this issue, Whipple et al. present an alternative hypothesis—that the change to a more erosive climate would lead to either a decrease or no change in relief in active mountain ranges, indicating a negative or non-existent coupling between cooling and mountain uplift.

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.
