It has major implications for atmospheric composition[1]. Climates are a massively dynamic system, and they work in really unintuitive and complicated ways. It's a pretty big misconception that we're capable of performing deductive reasoning about them. Even our stochastic workarounds aren't capable of dealing with them very well (see: the commonly joked about unreliability of predictive meteorology), which is why I generally take a very hard skeptical stance whenever I see this kind of conclusive language, outside of purely descriptive measures and careful talk about correlations. The climate is undergoing change that hasn't been seen since about 10k years ago, and that's about all we can say conclusively.
