摘要

Correlations between mean annual temperature (MAT) and the weighted average oxygen isotope composition of yearly precipitation (#delta#~(18)O_(pt)) are well-known, but the utility of modern relations to make reliable estimates of temperature change over geological time is uncertain. This question has been addressed by using seasonal subsets of the global data base of temperature and isotopic measurements to represent two different climate modes. A comparison of middle- to high-latitude #delta#~(18)O_(pt)/temperature relations for each climate mode reveals (1) a significant offset between them, and (2) a difference in the strength of their correlations. The offset is relations is due to differences in temperature and water vapor budget in the tropics, and can lead to serious underestimates of temperature change. Differences in the strength of correlations arise from the influence of climate mode-specific, non-temperature factors on #delta#~(18)O_(pt). The overall result is that no single relation can be used in all cases to make unambiguous temperature estimates using a temporal record of #delta#~(18)O_(pt) values. One way to overcome these problems is to reconstruct #delta#~(18)O_(pt)/temperature relations for the time periods being investigated. If an appropriate proxy for #delta#~(18)O_(pt) is available, it may also be possible to estimate temperature without relying on #delta#~(18)O_(pt)/temperature relations. A promising alternative to these options is to use records of #delta#~(18)O_(pt) to test predictions of global climate models, an approach that may allow a reliable and more complete reconstruction to be made of climate change over geologic time.

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.
