摘要

The permafrost wetlands in the Great Hing'an Mountain valleys are degenerating in response to climatic warming and retreat of permafrost. Changes in vegetation productivity are an important aspect in the studies on permafrost wetlands in response to global change. We investigated the vegetation productivity aboveground in the 12 permafrost wetlands in the Great Hing'an Mountain valleys along a latitudinal gradient. The results indicated a significant latitudinal gradient in herbage productivity, which was determined primarily by temperature. Linear regression demonstrated an 80 g· m~(-2) increase in herbage productivity with an increase of annual temperature by 1°C. If temperatures increased 2-4°C over the next century, herbage productivity would increase 2-4 times in predominantly continuous permafrost, and 57-114% in island permafrost. Shrub productivity and community productivity had no significant relationships with latitude, but they tended to increase first, and then decrease with the increase of mean precipitation in July.

6. 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.
