Recent research indicates that acid oceans likely contributed 
to Earth’s worst mass extinction.

Dr. Peter Ward has published a book that discusses decades of 
published research, which he has conducted into the Permian- 
Triassic mass extinctions. It is: 
 
Ward, P. D., 2008, Under a Green Sky. Harper-Collins Books. 
242 pp. ISBN 978-0-06-163163-4 
 
It is an excellent, entertaining, and thoughtful book about the
Permian-Triassic mass extinctions that is well written for the 
general public.
