This review explains the science behind the drive for global net zero emissions and why this
is needed to halt the ongoing rise in global temperatures. We document how the concept of …

Equilibrium climate sensitivity characterizes the Earth's long-term global temperature
response to increased atmospheric CO2 concentration. It has reached almost iconic status …

Working Group I (WGI) of the Intergovernmental Panel on Climate Change (IPCC) assesses
the current evidence on the physical science of climate change, evaluating knowledge …

Results from the fully-, biogeochemically-, and radiatively-coupled simulations in which CO
2 increases at a rate of 1% per year (1pctCO2) from its pre-industrial value are analyzed to …

Climate models have continued to be developed and improved since the AR4, and many
models have been extended into Earth System models by including the representation of …

This chapter addresses the biogeochemical cycles of carbon dioxide (CO2), methane (CH4),
and nitrous oxide (N2O). The three greenhouse gases have increased in the atmosphere …

Most of the policy debate surrounding the actions needed to mitigate and adapt to
anthropogenic climate change has been framed by observations of the past 150 years as …

The responses of carbon dioxide (CO 2) and other climate variables to an emission pulse of
CO 2 into the atmosphere are often used to compute the Global Warming Potential (GWP) …

Abstract The Zero Emissions Commitment (ZEC) is the change in global mean temperature
expected to occur following the cessation of net CO 2 emissions and as such is a critical …

The magnitude and evolution of parameters that characterize feedbacks in the coupled
carbon–climate system are compared across nine Earth system models (ESMs). The …
