The earth has been alot hotter at various times in its history than it currently is, before humans appeared. The earth has been alot cooler as well.The fact that climate swings both ways is not disputed by anyone. Looking at climate change in a period as short as recorded human history , let alone the course of a single human life isn't very telling of anything. It's a political agenda driven by people who deep down really hate people and what they've done to the planet. Yet they won't do the single thing that would most help to stop it if it is driven by human activity. Stop breeding! Your carbon footprint includes all of your progeny and their carbon footprints as well.
