      The earth’s magnetic field is due to the motion of molten iron compounds in the outer core, whereas climate change affects the earth’s atmosphere (and to a small extent the earth’s crust), so basically the answer is no, though I am sure that there will some be some very small effects as the earth is one whole system.
