You clearly don't understand what is happening. The increase in CO2 causes wilder swings in weather, leading to more and more extremes. It also perturbed the Jet Stream, leading us to get in the USA what had been weather confined to the Arctic. This outcome is PRECISELY what had been predicted for the worst effects of climate change.

In fact, the amount of CO2 that we have already released has triggered the knock-on effects, which is the melting of permafrost and the subsequent release of vast quantities of Methane gas, which is 84 times more damaging than CO2.

Unfortunately, climate is not simple. By definition it is a complicated effect. But the coldest February ever seen is 100% in agreement with the predictions in Climate change.
