Pointing the finger

Attributing ocean acidification to major carbon producers extends anthropogenic atmospheric CO2 attribution to the ocean. The paper explores major historical contributors to ocean acidification, and the spatially nonuniform effects of CO2 absorbed into the ocean to reduced pH. 

The effects of emissions don't always redound to emitters, as usual, or at least so far. As drastic costs are imposed on various societies as climate change become a tangible matter, it's not surprising that people will become interested in discerning winners and losers, and especially identifying culpability. We're wired for fairness ,which is why we've spawned so many laws and lawyers. Busy times ahead. From the abstract:

Using an energy balance carbon-cycle model, we find that emissions traced to the 88 largest industrial carbon producers from 1880–2015 and 1965–2015 have contributed ~55% and ~51%, respectively, of the historical 1880–2015 decline in surface ocean pH. As ocean acidification is not spatially uniform, we employ a three-dimensional ocean model and identify five marine regions with large declines in surface water pH and aragonite saturation state over similar historical (average 1850–1859 to average 2000–2009) and recent (average 1960–1969 to average of 2000–2009) time periods. We characterize the biological and socioeconomic systems in these regions facing loss and damage from ocean acidification in the context of climate change and other stressors. Such analysis can inform societal consideration of carbon producer responsibility for current and near-term risks of further loss and damage to human communities dependent on marine ecosystems and fisheries vulnerable to ocean acidification.

Timm and Maibach scrutinize television weather forecasters and their presentations of climate change, in The Prevalence and Rationale for Presenting an Opposing Viewpoint in Climate Change Reporting: Findings from a U.S. National Survey of TV Weathercasters. As journalists of a kind, broadcast forecasters are subject to norms of "balance" and hence can be found creating what might be termed "dark mass" in the form of giving excess heft to what less polite people might call fringe beliefs, in an attempt to present "both sides" of the story. Of course, this is problematic when it comes to genuinely weighty topics that are no longer a matter of opinion: 

The journalistic norm of balance has been described as the practice of giving equal weight to different sides of a story; false balance is balanced reporting when the weight of evidence strongly favors one side over others—for example, the reality of human-caused climate change. False balance is problematic because it skews public perception of expert agreement. Through formative interviews and a survey of American weathercasters about climate change reporting, we found that objectivity and balance—topics that have frequently been studied with environmental journalists—are also relevant to understanding climate change reporting among weathercasters. Questions about the practice of and reasons for presenting an opposing viewpoint when reporting on climate change were included in a 2017 census survey of weathercasters working in the United States (N = 480; response rate = 22%). When reporting on climate change, 35% of weathercasters present an opposing viewpoint “always” or “most of the time.” Their rationale for reporting opposing viewpoints included the journalistic norms of objectivity and balanced reporting (53%), their perceived uncertainty of climate science (21%), to acknowledge differences of opinion (17%), to maintain credibility (14%), and to strengthen the story (7%).
