Quantification of the likely contributions of greenhouse gases and other forcing factors to past temperature change (Section 9.4.1.4) in turn provides observational constraints on the transient climate response, which determines the rapidity and strength of a global temperature response to external forcing (see Glossary and Sections 9.6.2.3 and 8.6.2.1 for detailed definitions) and therefore helps to constrain likely future rates of warming.

This is because over the past three years, hundreds of new scientific field accounts of global warming's impacts, as well as improved peer - reviewed analyses of global warming itself in both the deep past and the very near future, have depicted earth's atmosphere as far more «sensitive» to the invisible CO2, methane and other human - sourced greenhouse gases than had been hoped.
