Acid Oceans, Not Asteroid Impacts, Contributed to Permian – Triassic Extinctions
Recent research indicates that acid oceans, not asteroid
impacts, 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 lay public. I highly recommend it.
