Kardashians Get 40 Times More News Coverage than Ocean Acidification
By Shauna Theel
Carbon dioxide emissions are not just warming up our atmosphere, they're also changing the chemistry of our oceans. This phenomenon is known as ocean acidification, or sometimes as global warming's "evil twin" or the "osteoporosis of the sea." Scientists have warned that it poses a serious threat to ocean life. Yet major American news outlets covered the Kardashians over 40 times more often than ocean acidification over the past year and a half.
Rising carbon dioxide emissions have caused the oceans to become around 30 percent more acidic since the Industrial Revolution, and if we do not lower the amount of CO2 in the atmosphere, the ocean surface could be up to 150 percent more acidic by 2100. At that level, the shells of some plankton would dissolve, large parts of the ocean would become inhospitable to coral reef growth, and the rapidity of the change could threaten much of the marine food web. According to the National Research Council, the chemical changes are taking place "at an unprecedented rate and magnitude" and are "practically irreversible on a time scale of centuries."
Despite a boom of recent scientific research documenting this threat, there has been a blackout on the topic at most media outlets. Since the end of 2010, ABC, NBC and Fox News have completely ignored ocean acidification, and the Los Angeles Times, USA TODAY, Wall Street Journal, MSNBC, CNN and CBS have barely mentioned it at all.
While most coverage described the basic scientific phenomenon or listed ocean acidification as a serious environmental challenge, the Wall Street Journal dismissed the problem. All three mentions of ocean acidification from the Journal were from columns that downplayed the threat—there was not a single straight news article interviewing scientists. One of those columns was a full article devoted to distorting and cherry-picking the science on ocean acidification. The Journal also published a letter to the editor (not counted in this study) from the Competitive Enterprise Institute's Chris Horner who summarily dismissed ocean acidification as "the latest nominee to supplant troubled CO2-warming theory." But the threat is nothing to shake off.
Since the Industrial Revolution, global surface temperatures have increased by about 1.4 degrees Fahrenheit. But we would have warmed up more if the ocean did not absorb about 30 percent of the CO2 we release into the atmosphere. At first scientists focused on the benefits of this absorption in reducing the amount of warming expected to result from CO2 emissions. But more recently they have been studying how dissolved CO2 is increasing the acidity of the ocean. These changes are happening rapidly, harming the ability of species to adapt to them. As the National Research Council explained in a comprehensive 2010 report, the ocean ecosystems on which humans rely "evolved over millennia to an aqueous environment of remarkably constant composition," but are now facing major chemical changes due to human activities:
The chemistry of the ocean is changing at an unprecedented rate and magnitude due to anthropogenic carbon dioxide emissions; the rate of change exceeds any known to have occurred for at least the past hundreds of thousands of years. Unless anthropogenic CO2 emissions are substantially curbed, or atmospheric CO2 is controlled by some other means, the average pH of the ocean will continue to fall. Ocean acidification has demonstrated impacts on many marine organisms. While the ultimate consequences are still unknown, there is a risk of ecosystem changes that threaten coral reefs, fisheries, protected species and other natural resources of value to society.
Organisms forming oceanic ecosystems have evolved over millennia to an aqueous environment of remarkably constant composition. There is reason to be concerned about how they will acclimate or adapt to the changes resulting from ocean acidification--changes that are occurring very rapidly on geochemical and evolutionary timescales.
The following chart from the report shows that ocean pH remained fairly constant over hundreds of thousands of years and is projected to fall considerably during this century:
An increase in carbon dioxide directly lowers the pH levels of sea water, making it more acidic. Sea water is alkaline (basic), not acidic, but scientists use the term acidification to refer to the water becoming more acidic. Higher carbon dioxide levels reduce the amount of calcium carbonate minerals, with which many organisms form their shells and skeletons in a process called calcification. Ocean acidification will make it more difficult for many calcifying organisms like shellfish and coral to build their shells and skeletons and will cause the water to be more corrosive to some organisms' already built shells.
The sea butterfly, a snail-like type of zooplankton, could be the earliest victim of ocean acidification. As they awkwardly flap through the ocean, sea butterflies smaller than a lentil are eaten en masse by salmon and many other sea creatures. This makes them very important for the oceanic food web. But by 2050, they may not be able to form their shells in the Southern Ocean any longer. And by the end of the century, the projected acidity levels would dissolve their shells.
Coral reefs will also dramatically decline and several species of corals will face extinction if we do not reduce our carbon emissions. Coral reefs are the home to so much biodiversity that even though they make up less than 1 percent of the ocean, one in every four sea species depend on coral reefs.
Damaging ocean life could have costly impacts for humans: one study found that coral reefs alone provide a $29.8 billion global net benefit per year from fisheries, coastal protection, tourism/recreation, and biodiversity. Coastal communities, including those in Florida and Hawaii, would be hard hit by the loss of protection from storms and tourism from scuba divers and snorkelers.
And the impacts of ocean acidification on the oceanic food web would hurt many of the fisheries that provide 1.5 billion people a significant amount of food. Just earlier this year, scientists "definitively linked an increase in ocean acidification to the collapse of oyster seed production at a commercial oyster hatchery in Oregon, where larval growth had declined to a level considered by the owners to be 'non-economically viable,'" according to an Oregon State University press release about the study. Almost 50 percent of U.S. fishery revenue comes from shellfish and crustaceans, species that may be affected by ocean acidification because they depend on calcium carbonate to make their shells:
In sum, ocean acidification is a major threat to our oceans and the millions of people who depend on them for their food and livelihoods. Yet 77 percent of Americans say they have read or heard nothing about ocean acidification, according to a 2010 survey conducted for the Yale Project on Climate Change Communication. Of the 23 percent who say that they have heard of ocean acidification, only 32 percent understand that ocean acidification is caused by carbon dioxide. In other words, less than 8 percent of Americans understand the very basics of one of the largest threats to our oceans—and a major culprit for that ignorance is the national media.
This Media Matters study is based on a search of Nexis and Factiva from January 1, 2011 through the morning of June 26, 2012. The search terms used for Nexis were: "(ocean! w/10 acid!) or (ocean! w/10 carbon) or (ocean! w/10 chem!)" and the equivalent search was used for the Wall Street Journal at Factiva. For the daytime programming at MSNBC and Fox News, we searched an internal database for terms such as "ocean" and "acidic." The study included articles in all sections of the newspapers, but did not include any newswire reports that were run in the paper. A newspaper article whose focus was on ocean acidification was labeled a "full article," and any mention less than a full article was labeled a "mention"; a TV segment that explained ocean acidification at some length was labeled a "full segment," and any segment that mentioned that oceans were becoming more acidic was labeled a "mention."
The results for the Kardashians were based on a Nexis and Factiva search for "Kardashian!" and included all results. These results do not include daytime programming for Fox News and MSNBC because they are not in the Nexis database.

Natural gas is a versatile fossil fuel that accounts for about a third of U.S. energy use. Although it produces fewer greenhouse gas emissions and other pollutants than coal or oil, natural gas is a major contributor to climate change, an urgent global problem. Reducing emissions from the natural gas system is especially challenging because natural gas is used roughly equally for electricity, heating, and industrial applications.

What RNG Is and Why it Matters<p>Most equipment that uses energy can only use a single kind of fuel, but the fuel might come from different resources. For example, you can't charge your computer with gasoline, but it can run on electricity generated from coal, natural gas or solar power.</p><p>Natural gas is almost pure methane, <a href="https://www.eia.gov/energyexplained/natural-gas/" target="_blank">currently sourced</a> from raw, fossil natural gas produced from <a href="https://www.eia.gov/energyexplained/natural-gas/where-our-natural-gas-comes-from.php" target="_blank">deposits deep underground</a>. But methane could come from renewable resources, too.</p><p><span></span>Two main methane sources could be used to make RNG. First is <a href="https://www.epa.gov/ghgemissions/inventory-us-greenhouse-gas-emissions-and-sinks" target="_blank">biogenic methane</a>, produced by bacteria that digest organic materials in manure, landfills and wastewater. Wastewater treatment plants, landfills and dairy farms have captured and used biogenic methane as an energy resource for <a href="http://emilygrubert.org/wp-content/uploads/2019/02/eia_860_2017_map.html" target="_blank">decades</a>, in a form usually called <a href="https://www.eia.gov/energyexplained/biomass/landfill-gas-and-biogas.php" target="_blank">biogas</a>.</p><p>Some biogenic methane is generated naturally when organic materials break down without oxygen. Burning it for energy can be beneficial for the climate if doing so prevents methane from escaping to the atmosphere.</p>
Renewable Isn’t Always Sustainable<p>If RNG could be a renewable replacement for fossil natural gas, why not move ahead? Consumers have shown that they are <a href="https://www.nrel.gov/analysis/green-power.html" target="_blank">willing to buy renewable electricity</a>, so we might expect similar enthusiasm for RNG.</p><p>The key issue is that methane isn't just a fuel – it's also a <a href="https://www.eia.gov/environment/emissions/ghg_report/ghg_overview.php" target="_blank">potent greenhouse gas</a> that contributes to climate change. Any methane that is manufactured intentionally, whether from biogenic or other sources, will contribute to climate change if it enters the atmosphere.</p><p>And <a href="http://doi.org/10.1126/science.aar7204" target="_blank">releases</a> <a href="https://doi.org/10.1016/j.wasman.2019.07.029" target="_blank">will happen</a>, from newly built production systems and <a href="https://theconversation.com/why-methane-emissions-matter-to-climate-change-5-questions-answered-122684" target="_blank">existing, leaky transportation and user infrastructure</a>. For example, the moment you smell gas before the pilot light on a stove lights the ring? That's methane leakage, and it contributes to climate change.</p><p>To be clear, RNG is almost certainly better for the climate than fossil natural gas because byproducts of burning RNG won't contribute to climate change. But doing somewhat better than existing systems is no longer enough to respond to the <a href="https://doi.org/10.1038/nclimate2923" target="_blank">urgency</a> of climate change. The world's <a href="https://www.ipcc.ch/sr15/chapter/spm/" target="_blank">primary international body on climate change</a> suggests we need to decarbonize by 2030 to mitigate the worst effects of climate change.</p>
Scant Climate Benefits<p><a href="https://iopscience.iop.org/article/10.1088/1748-9326/ab9335/meta" target="_blank">My recent research</a> suggests that for a system large enough to displace a lot of fossil natural gas, RNG is probably not as good for the climate as <a href="https://investor.southerncompany.com/information-for-investors/latest-news/latest-news-releases/press-release-details/2020/Southern-Company-Gas-grows-leadership-team-to-focus-on-climate-action-innovation-and-renewable-natural-gas-strategy/default.aspx" target="_blank">is publicly claimed</a>. Although RNG has lower climate impact than its fossil counterpart, likely high demand and methane leakage mean that it probably will contribute to climate change. In contrast, renewable sources such as wind and solar energy do not <a href="https://www.eia.gov/environment/emissions/carbon/" target="_blank">emit climate pollution directly</a>.</p><p>What's more, creating a large RNG system would require building mostly new production infrastructure, since RNG comes from different sources than fossil natural gas. Such investments are both long-term commitments and opportunity costs. They would devote money, political will and infrastructure investments to RNG instead of alternatives that could achieve a zero greenhouse gas emission goal.</p><p>When climate change first <a href="https://www.nytimes.com/1988/06/24/us/global-warming-has-begun-expert-tells-senate.html" target="_blank">broke into the political conversation</a> in the late 1980s, investing in long-lived systems with low but non-zero greenhouse gas emissions was still compatible with aggressive climate goals. Now, zero greenhouse gas emissions is the target, and my research suggests that large deployments of RNG likely won't meet that goal.</p>

For all its posturing on climate change, the Democratic Party has long been weak on the actual policies we need to save us from extinction. President Barack Obama promised his presidency would mark "the moment when the rise of the oceans began to slow," and then embraced natural gas, a major driver of global temperature rise, as a "bridge fuel." Climate legislation passed in the House in 2009 would have allowed industries to buy credits to pollute, a practice known to concentrate toxic air in black and brown neighborhoods while doing little to cut emissions.

When an elephant dies in the wild, it's not uncommon to later find its bones scattered throughout the surrounding landscape.
Elephant Burial Grounds<p>Highly social creatures that form deep familial bonds, elephants have long been observed gathering at the site where a peer or family member has died — often spending hours, even days, quietly investigating the bodies or the bones of other dead elephants.</p><p>Although the popular idea that dying elephants are instinctively drawn to special communal graves — so-called "elephant graveyards" — is a myth, their tendency to go out of their way to visit the bones and tusks of the deceased isn't unlike human rituals at graveyards, says animal psychologist Karen McComb.</p><p>"They spend a lot of time touching and smelling skulls and ivory, placing the soles of their feet gently on top of them, and also lifting them up with their trunks," McComb, who's been studying African elephants for 25 years in Kenya's Amboseli National Park, told DW.</p><p>The most striking part of watching an elephant experience loss, Poole recalls, is the quietude. She still remembers one of the first elephant deaths she witnessed; a mother who birthed a stillborn calf. That elephant stayed with its baby for two days, trying to lift it and defending it from vultures and hyenas.</p><p>"I was so struck by the expression on her face and her body. She looked so dejected. It was really like, 'Oh God, these animals grieve…'. It was just so different," Poole told DW. </p>
Witnessing Emotions in Animals<p>Not all scientists are comfortable concluding that elephants grieve. Among the more than 30 reports of elephant reactions to death that Wittemyer co-reviewed in <a href="https://link.springer.com/article/10.1007/s10329-019-00766-5" target="_blank">a study published in November 2019</a> were accounts of "enormous variation and nuance" he says. "It can be incredibly involved and intricate for extended periods or can be relatively cursory checks."</p><p>In Wittemyer's own experience, it can be difficult not to attribute some kind of emotional experience to the more involved interactions between elephants and their dead.</p><p>He shares the story of an "extraordinary event" involving the death of a 55 year-old matriarch in Kenya in a protected area that happened to be near his place of work. She was visited by multiple unrelated families while she was dying, including another matriarch that exerted such enormous effort attempting to lift her to her feet that she broke her tusk, which Wittemyer says, is "like breaking a tooth." </p><p><span></span>"It was a remarkable example of this heightened emotional state, it was very clearly a very stressful interaction," he says.</p>
A Different Sensory World<p>One factor that limits our ability to fully grasp the way elephants process and respond to loss is our markedly different sensory experiences of the world.</p><p>An elephant's world is fundamentally olfactory — based on smell. Ours is visual. Previous <a href="https://pubmed.ncbi.nlm.nih.gov/25053675/" target="_blank">research</a> has shown elephants possess the most scent receptors of any mammal, and can <a href="https://pubmed.ncbi.nlm.nih.gov/17949977/" target="_blank">use smell</a> to discern the difference between different human tribes from the same local area.</p><p>That could explain why elephants exhibit such interest in sniffing the bones and tusks of others, as a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1617198/" target="_blank">2005 study</a> from McCombs highlighted. When presented with the skulls and ivory of long-dead elephants and those from other large herbivores, including rhino and buffalo, McCombs and her team found elephants approached and were specifically attracted to the remains of their own species. </p><p>Without access to the smells an elephant picks up on, Wittemyer says "an enormous amount of stuff" could be missed by humans when studying these behaviors.</p>
