The Fable of Chicken Little of the Sea
Guest essay by David Middleton,
When if comes to debunking Gorebal Warming, Chicken Little of the Sea (“ocean acidification”) and other Warmunist myths, my favorite starting points are my old college textbooks.
Way back in the Pleistocene (spring semester 1979) in Marine Science I, our professor, Robert Radulski, assigned us The Oceans by Sverdrup (yes, that Sverdrup), Johnson and Fleming. Even though it was published in 1942, it was (and may still be) considered the definitive oceanography textbook. I looked up “ocean acidification” in the index… It wasn’t there.
The notion that CO2 partial pressure influences the pH of seawater isn’t a new concept, *surely* ocean acidification must have been mentioned in at least one of my college textbooks.

Corals around Japan are fleeing northwards, according to a new study. One type has been spotted ‘sprinting’ at 14 kilometres a year, thanks to a lift from ocean currents. That means ocean ecosystems could shift rapidly in the face of climate-change impacts such as warming seas, the authors say.

Over millennia, the reef has adapted to sudden changes in environment by migrating across the sea floor as the oceans rose and fell.
The study published today in Nature Geoscience, led by University of Sydney’s Associate Professor Jody Webster, is the first of its kind to reconstruct the evolution of the reef over the past 30 millennia in response to major, abrupt environmental change.
The 10-year, multinational effort has shown the reef is more resilient to major environmental changes such as sea-level rise and sea-temperature change than previously thought but also showed a high sensitivity to increased sediment input and poor water quality. (…)

Scientists claim that the ocean’s global mean surface pH may have declined (i.e., became less alkaline and thus more “acidic”) by -0.08 in the last 265 years — from 8.13 during pre-industrial times to 8.05 today. That’s an overall, long-term pH change rate of -0.0003 per year.
By way of comparison, from one season to the next, or over the course of less than a year, pH levels naturally change by twice that amount (±0.15 pH units). On a per-decade scale, oceanic pH can naturally fluctuate up and down by up to 0.6 units within a span of a decade (as shown in red below).

A new study, published in Nature by serial reef alarmist Prof Terry Hughes, Director of the ARC Centre of Excellence for Coral Reef Studies at James Cook University, examines the link between the level of heat exposure from the 2015/16 super El Niño, “resulting in coral bleaching and ultimately coral death.“

Coral bleaching is becoming a serious issue for coral reefs under the stress of global warming. However, whether it has occurred in the past in times of thermal stress remains unclear. Moreover, an understanding of historic coral bleaching events would greatly improve our insight into the adaptive capabilities of corals under such stresses. It is known that Porites corals, a massive coral, have relatively high levels of symbiotic zooxanthellae and a strong thermal tolerance when compared with most other corals (and particularly branched corals). Thus, growth hiatuses and/or mortality surfaces of fossil Porites may be used to indicate past ecological or environmental stress events, such as severe bleaching. In this study, monthly geochemical and isotopic environmental proxies of four fossil Porites corals with well‐preserved growth hiatuses and mortality surfaces (aged 3,800–4,200 years before 2013 A.D.), collected from Wenchang fringing reef, Hainan Island, Northern South China Sea were analyzed. Specifically, the Sr/Ca, δ18O, and δ13C were measured with a monthly resolution for each sample.

By taking a closer look, scientists find resilience in face of heat stress.
Coral reef bleaching is stark evidence of the damage being inflicted by global climate change on marine ecosystems, but a research team has found some cause for hope. While many corals are dying, others are showing resilience to increased sea surface temperatures, pointing to possible clues to the survival and recovery of these vitally important aquatic habitats (…)

Coral reefs are facing no shortage of threats including ocean acidification, overfishing, plastic pollution, and rising temperatures. Sea surface temperatures have been climbing on average for over a century, and ocean heat waves—which can trigger coral bleaching events—are becoming more common and severe. Scientists have long worried that as coral-killing spikes in temperature become more frequent, corals won’t have enough time to recover between bleaching events and will ultimately go extinct. But a new paper, published today in PLoS Genetics, suggests that corals might be able to adapt to another century of warming.

WUWT readers may remember this story from last year, where Chris Turney, leader of the ill fated “ship of fools” Spirit of Mawson expedition that go stuck in Antarctic sea ice said: “Penguins Don’t Migrate, they’re dying!” and of course blamed the dreaded “climate change” as the reason. Of course three days later, Discover Magazine ran an article that suggested Turney was full of Penguin Poop.
Well, seems there’s a surplus of Penguins now, in a place nobody thought to look, there’s an extra 1.5 million Penguins. From Woods Hole Oceanographic Institute.

As the Earth’s surface and atmosphere warm, the amount of moisture – water vapour – in the atmosphere will increase. Understanding the size of this increase is important for predicting future climates as water vapour is a significant greenhouse gas. Atmospheric moisture content also influences the patterns and intensity of rainfall events.
The relationship between temperature and moisture content can be explored by the study of intervals in Earth’s history when climates where significantly warmer than those seen in modern times, which necessitates a method for estimating ancient atmospheric moisture content.

Some recent studies show declines in average weights of polar bears compared to the 1980s, but none recorded an increase in the number of individuals starving to death or too thin to reproduce.14 Although some photos of starving bears have garnered media attention, most bears have been found to be in good-to-excellent condition. In fact, photos of fat bears seem to outnumber those of thin bears in recent years.

The influence of pHsw on both pHcf and the calcification rate of Neogoniolithon is plotted in Figure 1 below. As indicated there, this coralline algal species is able to elevate its pHcf so as to increase its rate of calcification under moderate levels of ocean acidification (pHsw of 7.91 and 8.05), which increase the authors say is “most likely due to CO2-fertilization of [algal] photosynthesis” that is limited in Neogoniolithon at these lower pCO2 conditions.

Plastics make ideal vessels for colonizing microscopic organisms that could trigger disease if they come into contact with corals,” Lamb said. “Plastic items — commonly made of polypropylene, such as bottle caps and toothbrushes — have been shown to become heavily inhabited by bacteria

A 2010 analysis of 372 studies of 44 different marine species found that the world’s marine fauna is “more resistant to ocean acidification than suggested by pessimistic predictions” and that it “may not be the widespread problem conjured into the 21st century”
