I understand your point about the poles, but I see the telluric currents energizing the ice molecules, not simple old heat melting the ice.<quoted text>
Well, ignoring the fact that the largest contributors to greenhouse gases are all in the stratosphere, inert gases can make it all the way to the ozone, because they don't react with anything and only when they react with something do their weights actually change comparatively. But you are correct, they do keep adding "blankets" to the atmosphere. But the problem is that it's not likely to be the gases we release that tipped the climate change, but the energy near the glaciers that did.
For a pretty long time the earth has been collecting energies from space, and redirecting them within itself according to resistances within it. Those energies are almost all EM in nature, and the flows follow the path of least resistance. Too much resistance and you get earthquakes and such rearrangements. Climate is very much affected by this. The earth is a resistive conductor transferring energy from without and within.
Our industrial gases and other such endeavors have an indirect effect on the circuitry. What has a more direct effect is our EM production and emissions. They have a much more direct effect on the telluric currents. You stick that ground rod in the earth and you are connected. What you are pumping out in also pulling in from the earth. Supposed to all balance out, but it introduces resistances that effect the total flow. One interesting effect is the frequency disruption. Fifty and sixty cycle waves interacting with the Schumann resonance.
You are changing the potential values at the poles. The magnetosphere is polarizing incoming particles and waves that tend toward the poles. Setting up subcurrents energizing the ice molecules more than they would.
It is roughly like inducing an AC voltage upon a DC flow. Before the changes were dictated by cosmic forces hitting us. Now we are putting capacitors and resistors and inductors in that flow. Without a plan. Feedback to the normal flow.
Plus the heat from all of these computers.
