Every local climate is driven by air currents, by which I assume you mean jet stream changes driving pressure changes...aka cold/warm fronts. The jet stream is significantly controlled by the heights of the Alps and the Rocky mountain ranges in the northern hemisphere and the air currents are driven by the Earth's rotation. The Earth is not going to stop rotating and the mountains are not shrinking. This is why weather scientists have been consistent that noticeable changes from global warming will be more extreme weather not massive changes.
