英文摘要	An assessment of the risks of a seasonally ice-free Arctic at 1.5 and 2.0 °C global warming above pre-industrial levels is undertaken using model simulations with solar radiation management to achieve the desired temperatures. An ensemble of the CMIP5 model HadGEM2-ES uses solar radiation management (SRM) to achieve the desired global mean temperatures. It is found that the risk for a seasonally ice-free Arctic is reduced for a target temperature for global warming of 1.5 °C (0.1 %) compared to 2.0 °C (42 %), in general agreement with other methodologies. The SRM produced more ice loss, for a specified global temperature, than for CO2 mitigation scenarios, as SRM produces a higher polar amplification. © 2018 Author(s).
