CORALS are animals, closely related to jelly fish, but they differ in having a limestone skeleton. This is hard-stuff, calcium carbonate, and it can persist in the environment and provide an indication of changes in sea level, and also the growth rates of corals, over thousands of years.

Grim Future? Historical discussions of the human condition reveal that humans tend to identify themselves as members of like-minded groups. As discussed in the June 1 TWTW, in his farewell address, George Washington called such groups “factions.” Christopher Booker identified the common thinking of such factions as groupthink. In a post on his web site discussing Climategate, Roy Spencer addresses this issue stating that one of the few scientists who changed their mind after Climategate was Judith Curry: “She is now a well-informed and unabashed skeptic of the modern tendency to blame every bad weather event on humans.” He goes on to write:

Some corals can recover after massive mortality episodes caused by the water temperature rise. This survival mechanism in the marine environment -known as rejuvenation- had only been described in some fossil corals so far. A new study published in the journal Science Advances reveals the first scientific evidence of the rejuvenation phenomenon in vivo in Cladocora caespitosa coral colonies, in the marine reserve in Columbrets, in the coast of Castellón (Spain).
The authors of the study are the experts Diego Kersting and Cristina Linares, from the Department of Evolutionary Biology, Ecology and Environmental Sciences from the Faculty of Biology and the Biodiversity Research Institute (IRBio) of the University of Barcelona.

I recently had a (fairly short) conversation with an acquaintance, who was stunned to discover that I did not think at all highly of the position that Professors Terry Hughes and Ove Hoegh-Guldberg at James Cook University, Queensland, have taken on coral science and the Great Barrier Reef.
“Have you seen the documentary Chasing Coral?” I was asked, “There seems to be a lot of evidence that the reef is dying.” (or words to that effect).
I agreed to watch the documentary (if I’d known it went for a whole hour I might not have agreed so readily), and to report back when we next happened to be at the local cafe at the same time – an event which occurs from time to time. A bit like coral bleaching, perhaps.

Clash of Ideas: The Great Barrier Reef is a cultural icon for Australia. The world’s largest coral reef system stretches over 2300 km (1400 mi) and is home to a great diversity of sea life. Academics and scientific organizations have claimed that the reef is dying from global warming / climate change and ocean acidification (lowering of pH).

Good news continues to accumulate regards corals’ ability to rapidly adjust to changing climates. The view of coral resilience has been dominated by the narrative of a few scientists. In the 1990s they advocated devastating consequences for coral reefs due to global warming, arguing coral cannot adapt quickly enough. Since the Little Ice Age ended, they believed rising ocean temperatures had brought coral closer to a “bleaching threshold”, a more or less fixed upper temperature limit above which corals cannot survive.
Their model predicted the speed of recent global warming “spells catastrophe for tropical marine ecosystems everywhere”. Their assertions that “as much as 95% of the world’s coral may be in danger of being lost by mid-century” was guaranteed to capture headlines and instill public fear. However, a growing body of scientific research increasingly casts doubts on such alarming predictions. Unfortunately, that good news gets much less attention.
This unreliability of the science is now a widely accepted scandal in many other areas of study and it has a name: the replication crisis. When checks are made to replicate or confirm scientific results, it is regularly found that about half have flaws.

WUWT has posted several excellent articles by Jim Steele on how global warming alarmism uses corals as the poster child for warming and acidifying oceans, none of which is scientifically justified. A brief review follows, calling attention to a recently discovered additional adaptation mechanism not covered AFAIK by Jim Steele’s posts. The motivation for this post was triggered by a recent lunch with newish neighbor Charles the Moderator (CtM), and his sharing many wonderful underwater photographs of the coral reef he now dives frequently off Pompano Beach (same reef system as off Fort Lauderdale, just a few miles further north and more conveniently onshore). If any coral reef images appear in this post, CtM added them and gets the photocredits.

Some time ago it struck me that the majority of alleged environmental catastrophes and threats are invisible or very remote, thus making it virtually impossible for the average person to validate them through observation. Observations, along with replications of those observations, are the very foundation of the scientific method. Seeing is believing, and seeing the same result again and again under similar circumstances reinforces the belief. Is it possible that activist groups and the media choose to cite supposed catastrophes and threats that are invisible, very remote or both because the majority of people cannot verify them in person and therefore must rely on the activists, the media, and other third parties to tell them the truth? At the conclusion of this essay, the reader may judge. Here’s a list of some of the alleged invisible catastrophes and threats of doom, beginning with one of the former.
