In the news recently have been two revelations about the sometimes controversial world of coral reef research. The first is fraud allegations against research claiming that ocean acidification from global warming impairs the behavior of coral reef fish. The second is an about-face on inflated estimates for the extinction risk of Pacific Ocean coral species due to climate change.
The alleged fraud involves 22 research papers authored by Philip Munday, a marine ecologist at JCU (James Cook University) in Townsville, Australia and Danielle Dixson, a U.S. biologist who completed her PhD under Munday’s supervision in 2012. The fraud charges were made in August 2020 by three of an international group of mostly biological and environmental scientists, plus the group leader, fish physiologist Timothy Clark of Deakin University in Geelong, Australia. The Clark group says it will publicize the alleged data problems shortly.
The research in question studied the behavior of coral reef fish in slightly acidified seawater, in order to simulate the effect of ocean acidification caused by the absorption of up to 30% of humanity’s CO2 emissions. The additional CO2 has so far lowered the average pH – a measure of acidity – of ocean surface water from about 8.2 to 8.1 since industrialization began in the 18th century.
Munday and Dixson claim that the extra CO2 causes reef fish to be attracted by chemical cues from predators, instead of avoiding them; to become hyperactive and disoriented; and to suffer loss of vision and hearing. But Clark and his fellow scientists, in their own paper published in January 2020, debunk all of these conclusions. Most damningly of all, the researchers find that the reported effects of ocean acidification on the behavior of coral reef fish are not reproducible – the basis for their fraud allegations against the JCU work.

China’s climate history includes multiple climate warming and cooling fluctuations of 4°C within centuries, with cold periods aligning with declines in solar irradiance.
According to a new study (Zhang et al., 2021), northern China’s coldest temperatures of the last 5000 years occurred 300 calibrated years before present (cal yr BP), coinciding with the Little Ice Age and a decrease in solar irradiance. This frigid period was was followed by a ~4°C warm-up (from about 3.5°C to 7.5°C) within the span of about 150 years during the middle of the Qing Dynasty (1644-1912 CE), which was well before anthropogenic CO2 emissions began sharply rising.
The warmest temperatures of the last millennium occurred during the Medieval Warm Period (Song Dynasty, 960-1279 CE).
Rapid cooling periods of multiple degrees per century also coincided with the collapse of ancient civilizations, or dynasties, as wars and social unrest were often associated with competition for access to natural resources (such as water during droughts).

During the past week, the Pacific Northwest experienced the most severe heat event of the past century.
All-time high-temperature records were broken throughout the region, often by large margins. Many in the media, several local and national politicians, and some activist environmental scientists have claimed that this event was “driven by” or predominantly forced by human-inspired global warming (usually referred to as “climate change”).But such global warming claims are not supported by the facts and our best scientific understanding.
Truth and Rigorous Science About Climate Change is Necessary for Wise Decisions
In this blog, I will use observations, modeling, climatological data, and the peer-reviewed scientific literature to demonstrate that human-caused global warming played a very small role in the extreme heat event that we just experienced here in the Pacific Northwest.I will describe the origins of a meteorological black swan eventand how the atmosphere is capable of attaining extreme, unusual conditions without any aid from our species.As you read this, consider that I have actively pursued research on Northwest heatwaves, published several papers in the peer-reviewed literature on this specific topic, and have run both weather prediction and climate models that simulate such events. This subject is in my wheelhouse.
I also discuss the seriousness of misinformation. You and others can not make wise decisions when the information provided to you is not based on truth and science.
