Ocean burp hazard

For anyone who is still not terrified enough about global warming, here’s another scary possibility about how the Earth can revolt to our tampering.

Here’s a charming story (complete with video) about bacteria which thrive in warm oceans in low-oxygen conditions and produce sewer gas (hydrogen sulfide).  Enormous blooms of this gas are thought to be responsible for 4 mass extinctions and a dozen smaller ones, and are associated with warmer oceans caused by rising levels of carbon dioxide.  The warming trends of these past extinctions are thought to have been brought on by volcanic activity.  This time, we’re just doing it to ourselves.
