"Global cooling" is a great sop to those who want to keep right on using the ecosystem as a garbage dump. But the so-called "global cooling" phenomena are local weather purturbations that are caused by overall global warming.

Example:   the melting of the Greenland ice sheets dumps cold fresh water into the north Atlantic which disrupts the warm, heavier salt water flowing up in the Gulf Stream. It is the warm water of the Gulf Stream that keeps Northern Europe's climate moderate. Disruption of the Gulf Stream by the melting ice sheets could, more than likely, trigger extremely cold winters in Northern Europe.

But localized (even though apparently widespread) cooling of this type comes as a result of global warming.

Seeming small actions can have monumental effects down the line. The legendary fluttering of a butterfly's wings in the Amazonian jungle….

:-O    Eeeeeek!!
