Short summary
Recent studies have identified an approximately proportional relationship between global warming and cumulative carbon emissions. This relationship – referred to as the transient climate response to cumulative carbon emissions (TCRE) – is useful for climate policy applications. We show that the TCRE is constant for cumulative emissions lower than ~1500GtC but declines for higher cumulative emissions. We also find the TCRE to decrease with increasing emission rate.
