However, I would like to note that when the idea of a possible runaway global warming event occuring on earth was introduced it was purely speculation.

That is an assumption. You don't know what the requirement is.
It's no longer clear that the "Little Ice Age" was truly a global climatological phenomenon, or just one in Europe, where we have greatest records.
To assert that it is a "cyclical nature" of the Sun-Earth system requires physical mechanistic explanations, just like global warming from greenhouse gases did (and it has been verified with experiments and observations).
More speculation. Your comment makes the assumption that current reporting is correct. It makes the assumption that CO2 is the cause of warming (which it is not in this case) and that it has been validated which it has not as well. CO2 levels and temperatures have changed. You take the position that CO2 caused the change and that you are right. I say that is incorrect. I say that CO2 levels have changed as a result of temperature increases and therefore attempts to verify the Global Warming theory have failed. The models predicting the worst case scenarios have all failed.
If you look at the ice core temperature samples you will see something very obvious. The changes are cyclical. It is also VERY clear that CO2 decreases lag behind temperature decreases which fails the CO2 causing global warming claim. I can fabricate a model just as well as anyone else and I'm sure I can get someone to validate my claim. Does it make it right? Nope. But for some reason if I get a bunch of people to copy my work it somehow becomes right. At least that is modern climate science.
Global Warming supporters basically are taking the side in the "which came first? the chicken or the egg?" argument that the egg came first and the very existence of the chicken proves it.
Taking a position which is plausible but not provable doesn't make you right.
The Global Warming theory cannot be proven. We do not have the ability to determine whether CO2 is causing temperature changes or whether temperature changes are causing CO2 level changes because both are plausible.
However there is very solid evidence that on a number of occasions temperature changes plunged well in advance of CO2 changes. It throws a huge curve ball for those claiming that CO2 is the cause of change.
Based on the Global Warming theory it would be impossible for this to happen.
If reality was the reverse of the GW theory which I believe it to be you could explain with ease the drop in the temperatures in advance of the CO2 decline. Oh I'm sure someone will throw out a meaningless and unproven formula to try and explain it.
the changes in the future will be in any beneficial (cooling) or even more harmful (warming) direction
I believe you are completely incorrect here. In fact warming is beneficial while cooling is harmful. Warming, especially in the small amounts that would realistically be possible would result in longer growing seasons. It would expand the frost free safe zone for crops. It would mean fewer crop failures.
However cooling by even a small amount could be disastrous. There is plenty you can do to cope with an increase in temperatures like changing planting dates and adding irrigation systems. There is little you can do to cope with the cold. History is very clear on this. The consequences of cooling are well documented during the Little Ice Age and the period starting in 1812 caused by the Tambora eruption.
The reality is that nothing has been proven so until that point all doors are still open.

This is great news for the polar bears. With the lack of sea ice the last few years many have been forced to cannibalized. At least this winter it sounds like they will be eating seals.
