The Cryosphere. It is a 1 degree ensemble mean soil temperature of the 8 reanalysis and LDAS products (based on CFSR, ERA5, ERA5-Land, ERA-Interim, GLDAS-CLSM, GLDAS-Noah, JRA-55 and MERRA2), averaged over the near surface (0 - 30 centimeter, cm) and at depth (30 cm - 300 cm), between 1981-2018. All reanalysis products were remapped using a conservative remapping technique to a resolution of 1 degree latitude and longitude, based on the GLDAS-CLSM land-mask. The ensemble mean is calculated as a simple arithmetic mean of all eight products at each timestep for all grid cells that include valid soil temperature measurements for all 8 products.

Authors reported that the soil temperature bias is generally larger in the cold season, indicating the presence of soil freeze/thaw transition and snow layer introduced additional difficulties for soil temperature simulations. Authors also found that the ensemble generally outperforms any individual product. These findings improved the understanding of the current body of knowledge on soil temperature simulations in land surface models. However, a large part of the manuscript remained unfocused and an in-depth discussion is missing. I hence strongly suggest authors reformulate and shorten the manuscript (maybe as a brief communication) with a very specific focus on soil temperature validation.

This study explores the path dependence of the climate and carbon cycle response using an Earth system model of intermediate complexity forced with 24 idealized emissions scenarios across five cumulative emission groups (1275–5275 Gt C) with varying rates of emission. We find the century-scale climate and carbon cycle response after cessation of emissions to be approximately independent of emission pathway for all cumulative emission levels considered. The ratio of global mean temperature change to cumulative emissions – referred to as the transient climate response to cumulative carbon emissions (TCRE) – is found to be constant for cumulative emissions lower than � 1500 GtC but to decline with higher cumulative emissions. The TCRE is...
