Some nice pictures, also about the sea level changes, you find on this
thread
If temperatures raise, polar caps melt, but also water grows bigger (don't know how to call it in english? expand?)
If the polar caps melt, a lot of water flows to other places. So a lot of weight disappears. The weight on the polar cap disappears.
Is this enough to make tectonic plates tilt a little or something like that? I don't know if this question is already addressed here somewhere, but does anyone know an answer?
If tectonic would tilt, wouldn't it be nearly impossible now to make proper charts of land, after sea level has risen?
Bill, says here, the polar shift have been averted. How does one avert a polar shift? Seems to be a job for Superman, or Hercules

But seriously, how can it be averted, if a shift was realy on it's way?
