The Earth's Axis in Danger

The axis that controls the earth's seasons could shift in the coming decades.

If enough ice in the Earth's polar regions it could knock the earth's axis off center and the new found tilt could dramatically alter the intensity and the duration of the seasons.

The amount of ice in both the arctic and antarctic creates significant weight and pressure on the earth's core. If we remove all that weight it may cause the earth's axis to tilt more than usual, and for longer periods of time.

In theory if it tilted just 10% more southward than the northern hemisphere would endure record heats and the southern hemisphere would suffer exceptionally longer winters.

If it tilted 10% northward, the reverse would happen. Longer winters in the northern hemisphere and longer summers in the southern hemisphere.

It could also have dramatic effects on the magnetic poles, perhaps moving them as has happened previously in the earth's history, which could cause huge climate shifts if, for example, the new south pole found itself in Australia, and the new north pole in central Canada.

The point is we don't have a clue what would happen if the axis or the magnetic poles were shifted. We have no idea where they would shift to or whether they would even stay constant as they do right now.

It is usually best not to mess with such gravitational forces and tempt the chances of something going awry.
