Global Warming: Climate Change Basics

Greenhouse gases slow down the escape of heat radiating from the Earth's surface. Greenhouse gases are increasing. The resulting average international temperature increases are marked by an upward shift in world wide weather patterns. When Milankovitch cycles, climatic patterns on Earth brought about by "orbital forcing", do finally begin to push towards naturally occurring global warming trends, these cycles will be amplified by our unnatural levels of greenhouse gases. Even if we had stopped releasing them yesterday, these gases will remain for millennia. So, what now then?
