What made Ricke and Caldeira special, is that they took a single pulse only ~10 times larger than
the average human annual emission, and watched it until it reached maximum warming.
( in the same models used to reach high ECS levels)
Yes Humans continue to emit CO2 and continue to see annual increases, but each increase can be evaluated
by itself, and will reach it's own maximum warming in about a decade.
Ricke and Caldeira expressed it this way.
The IPCC's limited use of the two studies, is an attempt to downplay their impact,
If each annual CO2 growth step, will reach maximum warming in about a decade, then
much of the IPCC's warmings about the the warming being inevitable, is simply noise.
Emissions from 2022, will reach their own maximum warming by 2032, or earlier!
