Causes of extreme weather in western Europe at the beginning of this year

I think this should be related to the influence of global warming on the global ocean circulation. Ocean current exchange between high and low latitudes is an important way of heat exchange between high and low latitudes, and prevailing wind is a major driving force of ocean current, and the most fundamental factor for forming wind zone is the heat difference between high and low latitudes. Then, when the polar temperature rises, it will inevitably affect the dynamics of ocean circulation, leading to the weakening of some ocean currents. The extreme low temperature in winter in western Europe should be related to the weakening of the North Atlantic warm current. The north Atlantic warm current has a very significant impact on the climate in western Europe, and it has the function of warming and humidifying. In general, the winter temperature in coastal areas can be nearly 20 degrees higher than that in other areas of the same latitude.
