摘要

This study analyzes the potential to reduce air pollutants while achieving the 2 ℃ global temperature change limit target above pre-industrial levels, by using the bottom-up optimization model, AIM/Enduse [Global]. This study focuses on; 1) estimating mitigation potentials and costs for achieving 2 ℃, 2.5 ℃, and 3 ℃ target scenarios, 2) assessing co-benefits of reducing air pollutants such as NOx, SO_2, BC, PM, and 3) analyzing features of sectoral attributions in Annex I and Non-Annex I groups of countries. The carbon tax scenario at 50 US$/tCO_2-eq in 2050 can reduce GHG emissions more than the 3 ℃ target scenario, but a higher carbon price around 400 US$/tCO_2-eq in 2050 is required to achieve the 2 ℃ target scenario. However, there is also a co-benefit of large reduction potential of air pollutants, in the range of 60-80% reductions in 2050 from the reference scenario while achieving the 2 ℃ target.

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.
