I think what you may be referring to is the temperature in polar latitudes
undergoing warming seasonal averages. The effect is causing the poles
to lose iceshelf material.
The result is that the earth is losing ellipsoid shape, in small increments,
and warming ever so "slightly''.
I did a post on this, with my calculations, from A-Z.
I gave the scientific basis, but no one seemed too interested.
To save bandwidth, I remove my posts if they bore people.
I will not repeat that experience...but if I may.
The earth has a obloid core~~~.
This is due to the layers of the interior.
Of course, they are covered by the exterior. Top down, you have
watery mantle, then crust over viscous molten material, and in the center,
a molten liquid core. As it rotates, with the earth, it displaces the
liquid core into, or rather it tosses it outward, against the higher viscous
layer. Where it contacts cooler, viscous material, the molten core loses
energy and heat, and makes semi-solids.
These line up and accrete tothe midline of the core, which increases the gravity/density along the midline of the core.
The sun and the moon 'tug' at this buildup, and it all creates the bulge
that exists at the equatorial line. The bulge amounts to some
15-1600 kilometers difference, between the polar circumference,
and the greater circumference at the equator.
As the poles melt, weight is displaced further south, by water migration.
This weight flatens the poles, as well, so as it is displaced by ice/water
migrationsouthward, the poles are less flat. The climate is also somewhat
perturbed.
What melts the poles?
Greenhouse gases, El Nino and La Nina, Ozone Holes, volcanic dust,
solar flares and storms, and more infrared energy.
This almost deals with your question, it is a page I made.

magnetic fields, and the effects of gravity.
You might want to branch out, a small bit, and look a site I mention.
Before you do, just consider...
People map the earth and chart the weather.
To measure the world, the survey it.
To present their data, they often refer to the mean (medium) sea-level.
This is called the geoid of the world.
It describes the world as an irregular ellipsoid, which in fact it is.
Geoid. The world and its shape, in the eyes of many scientists.
So, the world is irregular, with mantle plates piling over one another.
This increases local density, and gravity. The topography of the ocean's
bottom is irregular, thus, and the gravity on the ocean varies.
This may have some effect on the weather, ultimatley.
I did an extensive explanantion of gravity, and investigations into it.
But, I removed them...
Here is a map, a gravity model. It shows the subluxing (under) in the Indian Ocean mantles which went under the Himalayas, and also the
South Pacific densities.
