It is interesting to note that the statistical evidence for global warming is relatively weak (at least compared to particle physics, where 3 to 5 sigma is expected for discoveries), https://wattsupwiththat.com/2016/04/07/no-statistically-sign... it is only because we have a known causal mechanism that we can say with confidence that man-made global warming is occurring. I liked that this article focused on causes of global temperature change, even if it did not present the data in a good manner.
