Reports: Ocean Acidification Heats Planet, Changes Ecosystems

Two new studies showcase the greater dangers of rising ocean temperatures.

The first, in the journal Nature Climate Change, finds rising carbon dioxide levels that make oceans more acidic can also raise global temperatures. The authors find ocean acidification would lead certain marine organisms to emit less of the sulphur compounds that help with cloud formations that cool Earth. When the data were fed into climate models, the authors estimated reduction of this compound could add nearly 0.5 degrees Celsius to global temperatures this century.

A second paper in the same journal focuses on how acidification will change marine ecosystems. The authors looked at 167 studies on more than 150 species under a wide range of carbon dioxide concentrations.

“Our study showed that all animal groups we considered are affected negatively by higher carbon dioxide concentrations,” said study co-author Astrid Wittmann. “Corals, echinoderms and molluscs above all react very sensitively to a decline in pH value.”

Seas are naturally slightly alkaline, but pH levels fall as oceans absorb carbon dioxide from the atmosphere. The research is expected to be included in the United Nation’s Intergovernmental Panel on Climate Change’s fifth Assessment Report on climate science. An early leaked draft of the U.N. report shows ocean temperatures rose more than 0.18 degrees Fahrenheit each decade of the last 40 years (through 2010).

McCabe Could Be Next EPA Air Chief

Janet McCabe, a deputy administrator at the U.S. Environmental Protection Agency’s clean-air office, is expected to be nominated by President Barack Obama to lead the office, the National Journal reports. If selected, McCabe would spearhead efforts to craft new pollution regulations for the nation’s coal-fired power plants, which she discusses in a recent EPA webinar. Timing of an announcement regarding a nomination, however, was unclear to sources (subscription).

Keystone XL Decision in Danger of Delay

Results of an investigation into conflict of interest complaints related to the Keystone XL pipeline may not be released until early 2014. The announcement by the State Department’s Office of the Inspector General (OIG) means a final decision on the project could be delayed until next year.

“It is our hope to conclude work by the end of the year and release a report in January,” said Douglas Welty, an OIG spokesman. “As to the timing of the department’s decision—you need to ask them directly whether our work will have an impact on that.”

A story in the National Journal suggests one portion of the pipeline—proposed back in 2008—may have become obsolete.

“They just waited too long. The industry is very innovative, and it finds other ways of doing it and other routes,” said Continental Resources CEO Harold Hamm, of the portion of the pipeline that would carry oil from fields in North Dakota to Montana.

Climate Change Considerations in Wake of Sandy

A presidential task force created after Hurricane Sandy has issued a 200-page report with 69 policy recommendations to promote stronger construction as climate change contributes to more intense storms and extreme heat. Among other actions, it calls for more advanced energy infrastructure and streamlined assistance for affected communities.

“Decision makers at all levels must recognize that climate change and the resulting increase in risks from extreme weather have eliminated the option of simply building back to outdated standards and expecting better outcomes after the next extreme event,” the report says.

It includes a 15-page section dedicated to threats due to climate change. Many of the initiatives suggested to deal with these threats, such as a minimum flood risk standard, have already been put into action (subscription).

Meanwhile, House Republicans are planning a hearing on the White House’s climate change agenda with leaders of 13 federal agencies next month. It is expected to touch on the science underpinning global climate change.

EPA Finalizes Biofuel Mandate

Editor’s Note: The Climate Post will take a break from circulation the next two weeks. We will return to our regular posting schedule August 29.

The U.S. Environmental Protection Agency (EPA) announced final 2013 biofuel volume requirements under the Renewable Fuel Standard. Issued Tuesday, the final rule lowers targets for biofuels production in 2014—requiring that 16.55 billion gallons of renewable fuels be blended into the U.S. fuel supply including 1.28 billion gallons from biomass-based diesel fuel and 2.75 billion gallons from advanced biofuels. These are the same quotas proposed by the EPA in February. The agency’s initial 14 million gallon cellulosic biofuel quota, however, was dropped to 6 million gallons.

Additional time was also given for refiners to meet 2013 volume quotas. The EPA now requires compliance by June 30, 2014—a four-month extension. When it comes to future quota limits, the EPA says it will utilize “flexibilities” in the law to reduce the amount of biofuel needed next year, when a “wall” is projected.

The Washington Post offers some backstory on why the targets—which were supposed to hit 16.55 billion gallons in 2013 and rise to 36 billion gallons in 2022—have been hard to reach.

Study: Sea Level Rise Threatens to Put Cities Underwater

A new study finds rising sea levels will threaten some 1,400 cities and towns in the United States by 2100 if global emissions continue to increase. Prior emissions have locked in 4 feet of future sea level rise, the study suggests, and 3.6 million Americans live in 316 municipalities already at risk, in places such as New Orleans, Fort Lauderdale and Atlantic City. Should global emissions continue to increase, the study states that the world may experience 23 feet of sea level rise by the end of the century, putting more than 1,000 cities and towns at risk.

“The current trend in carbon emissions likely implies the eventual crippling or loss of most coastal cities in the world,” said Benjamin Strauss, a study author and Climate Central scientist. “It’s like this invisible threat.”

Keystone XL Decision Could Experience Further Delays

Although President Barack Obama vowed to rule before 2014 on the Keystone XL pipeline—which would carry crude oil from Canada to the Gulf of Mexico—an upcoming trial could delay a final decision (subscription). The suit, set for trial in Nebraska Sept. 27, contends the Nebraska state legislature unconstitutionally gave Gov. Dave Heineman authority to approve the pipeline’s route. A win could force a more than 1,000-mile leg of the project to go through the siting process again.

Mother Jones reports that another pipeline project is quietly moving ahead. The 774-mile Eastern Gulf Crude Access Pipeline project would run from Illinois to Louisiana and is projected to carry oil quantities similar to those that could flow through the Keystone XL by 2015.

Warming Climate Linked to More Violent Behavior

When temperatures rise, so does aggression, according to a new study in the journal Science. The analysis looked at several dozen studies examining the relationship between climate and conflict in most regions of the world over the last 10,000 years. It revealed that even slight spikes in temperature have increased the risk of personal violence and social upheaval throughout history, a finding that could have critical implications for understanding the impact of climate change on future societies.

“Past climatic events have exerted significant influence on human conflict,” the study authors wrote (subscription). “If future populations respond similarly to past populations, then anthropogenic climate change has the potential to substantially increase conflict around the world, relative to a world without climate change.”

Some national security experts and scholars are skeptical of the conclusion, questioning whether the link to climate change is established and citing prior studies that suggest the opposite connection is true. Authors of the Science study have taken on some of these critiques.

McCarthy: Climate Change Is “Opportunity of a Lifetime”

In her first public speech, newly minted U.S. Environmental Protection Agency (EPA) Administrator Gina McCarthy vowed to curb climate-altering pollution, an effort that she said would spark business innovation, grow jobs and strengthen the economy. McCarthy, who was confirmed to lead the EPA in July after pushbacks from Republicans, spoke before an audience in her native Boston.

“Let’s talk about this as an opportunity of a lifetime, because there are too many lifetimes at stake,” McCarthy said of regulating emissions, noting the EPA will work to develop a “new mindset about how climate change and environmental protection fits within our national and global economic agenda.”

Although the EPA has met some opposition from industry groups and Republicans who say environmental regulation hurts the economy, McCarthy said she planned to continue issuing new rules and felt President Barack Obama’s new Climate Action Plan could “fuel the complementary goals of turning America into a magnet for new jobs and manufacturing.”

A key part of Obama’s plan is upcoming regulation of emissions from new and existing power plants under the Clean Air Act. McCarthy said every dollar spent so far on Clean Air Act rules has produced $30 in benefits, with health benefits outweighing the cost of air regulations 30 to 1.

Role of Coal in Energy Future

Though coal accounts for nearly 45 percent of global energy-related carbon emissions, its use continues to rise. In fact, the Energy Information Administration finds that coal use will grow faster than petroleum and other liquid fuels use until after 2030—partially due to China’s increased consumption.

U.S. Energy Secretary Ernest Moniz on Monday told employees of the National Energy Technology Laboratory in Morgantown that coal and other fossil fuels “will be a major part of our energy futures for decades.” The speech comes roughly a month after Obama laid out a plan to reduce greenhouse gas emissions and increase both clean energy production and energy efficiency. Moniz said the administration has spent about $6 billion on clean coal technologies, specifically technologies that capture, store and reuse carbon emissions.

Pace of Some Renewable Energy Efforts Slow

An energy efficiency bill expected for a floor debate this week now won’t be considered until after the Senate’s August recess. The National Journal looks at why passing the bill, which encourages energy conservation by homeowners, manufacturers and the federal government through several measures, is harder than one might think.

In Florida, a biorefinery plant became the world’s first to produce commercial quantities of cellulosic ethanol from wood waste and lawn clippings. Numbers were not released, but shipments from INEOS Bio in Vero Beach will begin in August. The industry has fallen short of the federal renewable fuel targets for ethanol made from cellulose (subscription required).

“Unlocking the potential for the responsible development of all of America’s rich energy resources is a critical part of our all-of-the-above energy strategy,” said Moniz. “Today’s announcement of commercial-scale cellulosic production represents an important benchmark for American leadership in this growing global industry. It also demonstrates the need for early-stage investment in innovative technologies that will help diversify our energy portfolio, reduce carbon pollution and lead to tomorrow’s energy breakthroughs.”
