My own studies show that we are headed into a period of Climate Stagnation wherein the temps will neither rise nor fall. The consequences will be devastating.
"The tilting of the Earth as it rotates around its own axis also makes the polar ice cap grow, and this affects the air masses around it."
Global warmers don't take the tilting of the Earth into account, as well as other factors (such as Sun spots and solar radiation). As a matter of fact, the tilt of the Earth is constantly changing, and is due for a major correction that will be accompanied by a flipping of the magnetic poles (north and south exchange positions). This will have a major effect on global temperatures and climate.
Mankind is puny, and any climate change is driven by nature. Earth's climate is constantly changing, and the Earth will recover despite man's presence here.
