The equilibrium climate sensitivity (ECS) has a large uncertainty range among models participating in the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4) and has recently been presented as ‘‘inherently unpredictable.’’ One way to circumvent this problem is to consider the transient climate response (TCR). However, the TCR among AR4 models also differs by more tha...

The oxidative capacity of past atmospheres is highly uncertain. We present here a new climate–biosphere– chemistry modeling framework to determine oxidant levels in the present and past troposphere. We use the GEOS-Chem chemical transport model driven by meteorological fields from the NASA Goddard Institute of Space Studies (GISS) ModelE, with land cover and fire emissions from dynamic global v...
