How often have you heard that coral reefs are fragile and would be wiped out by global warming?
If you google “fragile coral reefs” (without the quotes) you’ll get 493,000 hits. So imagine my surprise on stumbling on a news report titled, "Marine life flourishes at Bikini Atoll test site." The report tells us:
It was blasted by the largest nuclear weapon ever detonated by the United States but half a century on, Bikini Atoll supports a stunning array of tropical coral, scientists have found.
In 1954 the South Pacific atoll was rocked by a 15 megaton hydrogen bomb 1,000 times more powerful than the explosives dropped on Hiroshima.
The explosion shook islands more than 100 miles away, generated a wave of heat measuring 99,000ºF and spread mist-like radioactive fallout as far as Japan and Australia.
But, much to the surprise of a team of research divers who explored the area, the mile-wide crater left by the detonation has made a remarkable recovery and is now home to a thriving underwater ecosystem.
99,000 degrees Fahrenheit! By comparison the upper-bound estimate for global warming is a puny global temperature increase of 11.5 degrees Fahrenheit (less in the ocean). So even if global warming wipes out life on earth, global warming catastrophists can take comfort that nature will, as it inevitably must, reassert itself. Some, convinced that humanity is the problem, may even welcome such an outcome — no humans, but plenty of nature (over time). [Fifty-four years later at Bikini Atoll, recovery is not complete. Perhaps 28 percent of coral species may still be absent.]
Post Script: On the topic of corals and global warming, here’s an article on temperature tolerant corals off the coast of Eritrea, where waters can reach 98.6 degrees F, which incidentally is the average core body temperature of a human being.
