In radiation physics the technical term "saturated" implies that adding more molecules will not cause more warming.
In plain language this means that from now on our emissions from burning fossil fuels could have little or no further impact on global warming. There would be no climate emergency. No threat at all. We could emit as much CO2 as we like; with no effect.
This astounding finding resolves a huge uncertainty that has plagued climate science for over a century. How should saturation be measured and what is its extent with regard to the primary greenhouse gases?
