stop global warming !!

Is Global Warming real?

Earth's climate is changing. The result so far:

Global temperatures have risen 5° C
Glaciers have melted and retreated dramatically
Ecosystems around the world are being altered

This is not new news. These changes started 18,000 years ago, as the earth emerged from the Pleistocene Ice Age-- a time when ice-covered mammoths and mastodons roamed the earth.
Geologists know great ice sheets once covered large portions of the continents. These glaciers have alternately retreated and advanced as the earth has warmed and cooled, in cycles spanning hundreds, thousands, and millions of years.
Historical data from ocean sediments and ice cores indicate warm interglacial periods of 15,000 - 20,000 years separate each major ice age. We currently are in an interglacial period, and are due ( some say overdue ) for the next 100,000- year Ice Age.
