Are we heading for a new ice age sooner than we think? What is going on?

Although there has been many studies, Global warming due to greenhouse gases is inconclusive. Weather patterns are more to blame for drastic climate changes. In the current case as was evident 300 years ago, we are experiencing a global weather event. It all starts with upper level wind pattern changes. Without going into detail this changes migratory systems, but I digress. When a long period of heating occurs due to natural weather patterns, natural warm water currents in both the Pacific and Atlantic oceans flow farther north/south into glacier regions near both poles. The effect of this causes fresh water released from glaciers that, due to density differences, causes these warm salt water currents to discontinue warming surface water. This in turn causes temperatures to drop as warm water currents retreat further south. As this happens, the northern hemisphere becomes colder because of the retreating warm water currents. So, as warming causes glaciers to melt, the onset of fresh water originating from the poles disrupts the warm Water distribution that keeps the globe "normal". Therefore to much heating makes the warm currents go south and northern regions get colder and allows colder conditions to go equatorward. Historically these are referred to as mini ice ages. The last one happened recently causing the great potato famine roughly 300 years ago. In conclusion, although a brief time of CFC's released by spray cans in the 80s and 90s may have hurt the ozone some, these conditions have been reoccurring throughout history due to the unusual dispersant of fresh water from glaciers offsetting the natural warming flow of ocean water trying to balance the earths climate. Ironically, hot conditions will cause the above cold conditions and we continue in a cyclical manner until the earth ends.
