The question to ask about cooling trends is what triggers them, and what continues to sustain a 'triggered' cooling trend down to a more extreme
colder climate globally that brings about an established mini ice age or a full on ice age?
Fresh water freezes easier than salt water, and therein lies the clue for trigger. A warming trend will melt vast quantities of freshwater ice which
melts into the salt-rich seas, lowering the saline density. If there is no natural recuperation in salt richness, it will lead to larger ice cover as
the seas freeze over easier and faster. The more ice cover will then contribute to the general downward cooling (by reflecting more sunlight back into
space), blocking the natural mechanism for recuperation of salt density that would aid in blocking the growth of ice cover.
The battle between heating and cooling is a constant flux, but what obscures science's view for accurate assessment is the scale of the environment,
and the amount of variables needed to be included in climate models.
I think the establishment of a mini ice age is the first necessity for the establishment of a full on ice age. The shift from a warm trend to a
cooling trend is not sudden, but gradual and incremental with each passing year. A continued growth of ice cover would be a good indicator of a
cooling trend, but not without throwing up a few false positives at first. Some years will show greater ice cover than others. Only when ice cover
continues to grow with each passing year will the indicator be of a true and sustained cooling trend...leading perhaps, towards a mini ice age first,
and then if conditions continued to flow downward, leading to a self-feeding mechanism, the establishment of a full on ice age.
No cooling trend can begin without a reduction in the intake of solar radiation, which is the climate paradox, all cooling trends are triggered by
warming trends...a climate pendulum. For thousands of years a moderate global climate indicates natural mechanisms in place that regulate the climate
pendulum to swing moderately, but if some event (such as more volcanic eruptions globally) were to increase heat into the global environment, it could
lead to the inhibition or reduction in the efficacy of the natural regulating mechanisms, thus leading toward more ice melt, and more freshwater into
the seas destabilising the salt density, and allowing larger areas of the seas to freeze over. This would then lead to more sunlight being reflected
back into space, and the planet's heat retention being reduced, leading to a self-sustaining cooling trend.
The climate argument is about whether man's contribution of CO2 into the environment over the last few centuries has been sufficient enough to
establish a warming trend, and thus contributing to the disruption of the moderate climate regulatory mechanisms?
