GEOLOGY NEWS -

Earth's inner cycles may be behind long-term sea level rises and climate change, particularly ancient global warming.  A new study focuses on inner Earth's activities 60 to 140 million years ago.

Mantle plumes of lava appear to be cyclical, coinciding with periods of radical climate warming.
