Actually science is looking towards the affects of sun spots and solar storms on the earth's weather, more and more. Finding that the potential for returning to another mini ice age is very possible. Patterns and cycle suggest this all too strongly. Around the time of the Dark Ages is when the last recorded mini ice age happens. Rivers and ocean fronts froze to almost year round. Crops failed, one of the exceptions being potatoes and other root below ground crops. Diseases were uncontrolled.
Al Gore just stated he was mistaken about the release of CO2 gases, in the air, had much affect on the "Theory" of global warming. Global Warming has been used as a political tool and scare tactic for too long. Thr UN being the prime guilty party to all this.
Heat and food, when global cooling comes, will be the concern. The weather has always been the main factor, by far, to the survival of humans on earth. If and when a major ice age returns, than as before, most of the northern hemisphere will become glaciers or heavily encased in a frozen wasteland. A theory, long held, suggest that the excess mass of weight (glaciers/snow/ice) in the northern hemisphere will tip the balance of the planet, causing another shift of the axis. A major axis shift has happened at least 3 times before in the history of the earth. Some think more times than this.
