The relevant question is the sensitivity of the climate to CO2.

This may have caused us to overestimate climate sensitivity.

And as a result, they have overestimated climate sensitivity.

That’s because of the uncertainty of predictions of climate sensitivity.

This is the largest source of uncertainty in IPCC estimates of climate sensitivity.

The observational analysis implies that the models are exaggerating climate sensitivity.

This is the main source of the uncertainty in our calculation of climate sensitivity.

The results imply that the models are exaggerating climate sensitivity. ….

The results imply that the models are exaggerating climate sensitivity.

The results imply that the models are exaggerating climate sensitivity.

What are the limits on the climate sensitivity value?

Observations show climate sensitivity is not very high

Climate sensitivity describes how sensitive the global climate is to a change in the amount of energy reaching the Earth's surface and lower atmosphere.

Climate sensitivity describes how sensitive the global climate is to a change in the amount of energy reaching the Earth's surface and lower atmosphere (a.k.a. a radiative forcing).
