The North Pole and the South Pole are points; they do not have any size to them at all and, as a result, are neither growing nor diminishing.  Yes, the earth is tilted on its axis and has been for hundreds of thousands of years.  How has that tilt affected the climate in the last 40 years?  If your post pertains to the wobble around earth's tilted axis, yes, there is, indeed, a wobble, and that wobble slightly affects the earth's climate by about 10 meters.  Is the climate 10 meters north of you appreciably different than where you are now located?  Your post is evidence why our leaders need to make decisions based on science, not merely opinion.
