We used the Community Earth System Model, Version 1.2 (CESM1.2) (Hurrell et al., 2013), which includes the Community Atmospheric Model Version 5 (CAM5), the Community Land Model Version 4 (CLM4), the Community Ice Code Version 4 (CICE4), and the Parallel Ocean Version 2 (POP2). The CAM5 and CLM4 have a horizontal resolution of ~1°x1° and 30 vertical levels (Neale et al., 2010). The CICE4 and POP2 have 60 vertical levels, with a longitudinal resolution of 1° (the latitudinal resolution was ~1/3° near the equator and gradually increased to ~1/2° near the poles), with 60 vertical ocean levels (Smith et al., 2010).We performed two types of idealized climate model simulations. First, we integrated a 900-year long present-day (PD) control experiment with an atmospheric CO2 concentration of 367 ppm. We then conducted a CO2 ramp-up and ramp-down experiment for 500 years, branching from the 28 different initial conditions from the PD control. The CO2 concentration is increased by 1 % yr-1 for the first 140 years to ...
