As many readers know, considerable fear surrounds the future of the world’s coral reefs. Catastrophic declines have already occurred in some places, usually as a result of climate change combined with human activity like the dumping of sewage.

Now, however, comes a bit of good news. In research conducted off western Australia, scientists found that coral growth in that region had accelerated through the 20th century as ocean temperatures warmed. The effect was most pronounced at higher latitudes where the ocean tends to be colder — a strong indication that the warming caused by human release of carbon dioxide is benefiting corals in that region.
