CLIMATE CHANGE: what does it mean?

The words Climate Change have entered our vocabulary with hurricane force. It's difficult to pick up a newspaper, view the evening news, or read more than a few minutes on social networks, or the web without encountering these words. But what do they mean? Is climate really changing? How is it changing? Hasn't it always changed? Didn't we just recover from an ice age that ended only ten thousand years ago; and, didn't Europe just recover from a mini ice age that ended only a few centuries ago? So, what does climate change really mean? Does any one know? If these questions interest you, then please read on, as I try to shed some light on this complex, socio-political issue.
