Trump Takes A First Step Toward Scrapping Obama’s Global Warming Policy

WASHINGTON — The Trump administration will repeal the Clean Power Plan, the centerpiece of President Obama’s effort to fight climate change, and will ask the public to recommend ways it could be replaced, according to an internal E.P.A. document.
The draft proposal represents the administration’s first substantive step toward rolling back the plan, which was designed to curb greenhouse gas emissions from the power sector, after months of presidential tweets and condemnations of Mr. Obama’s efforts to reduce climate-warming pollution.
But it also lays the groundwork for new, presumably weaker, regulations by asking for the public and industry to offer ideas for a replacement.
The E.P.A. document, “October 2017 Tiering List,” lays out upcoming policy issues of high priority for the agency’s office of air and radiation, which oversees air pollution policies.
“The agency is issuing a proposal to repeal the rule,” the document states. It says the agency will issue a formal notice of its intention to develop a new rule “similarly intended to reduce carbon dioxide emissions from existing fossil-fueled electric utility generating units and to solicit information for the agency to consider in developing such a rule.”
The document does not explain how the Environmental Protection Agency will justify to the courts the decision to eliminate the regulation. Several industry attorneys familiar with the agency’s plans said they expected Mr. Pruitt to argue that the Obama administration relied on an overly-broad reading of federal clean air laws in writing the Clean Power Plan.
President Trump has vowed since the campaign to “get rid” of the Obama-era environmental regulations. He has called the Clean Power Plan “stupid” and “job killing,” and in an executive order issued in March he directed Scott Pruitt, the E.P.A. administrator, to dismantle the rules. Last month, Mr. Trump appeared to claim he had already done so, telling a crowd in Alabama, “Did you see what I did to that? Boom, gone.”
Killing the regulation also has been a high priority for Mr. Pruitt, who as attorney general of Oklahoma sued to overturn it in court.
But in recent weeks industry groups have pressed the Trump administration to fashion a new, narrower measure in its stead. Many have argued that creating such a replacement, rather than simply repealing the Clean Power Plan, is necessary to avoid lawsuits. Under a landmark agency determination known as the endangerment finding, the E.P.A. is required to regulate carbon emissions.
Mr. Pruitt has been under pressure from interest groups that deny the scientific consensus on climate change — that it is occurring and caused by human emissions — to overturn that determination. The E.P.A. document does not indicate Mr. Pruitt’s plans, but creating a new regulation implicitly accepts that the federal government has a role in addressing the reduction of carbon dioxide.
It remains unclear when the agency will formally repeal the rule. Liz Bowman, an E.P.A. spokeswoman, declined to comment on the document or plans for the rule.
The Clean Power Plan, which required states to cut greenhouse gas emissions from existing power plants by 32 percent by 2030 relative to 2005 has been tied up in litigation. The United States Court of Appeals for the District of Columbia had set an Oct. 7 deadline for the E.P.A. to show progress in its decision-making.
Brian Deese, who served as a senior adviser on climate change to Mr. Obama, said the E.P.A. was buying time. Asking the public for ideas, he said, is what an agency does when it is uncertain about how to proceed. Consideration of a new regulation could take months or even years, he said.
“They’re trying to walk this tightrope,” Mr. Deese said.

What Scientists Are Learning About The Impact Of An Acidifying Ocean

Oceans Deeply - Matthew O. Berger

The effects of ocean acidification on marine life have only become widely recognized in the past decade. Now researchers are rapidly expanding the scope of investigations into what falling pH means for ocean ecosystems.

The ocean is becoming increasingly acidic as climate change accelerates and scientists are ramping up investigations into the impact on marine life and ecosystems. In just a few years, the young field of ocean acidification research has expanded rapidly – progressing from short-term experiments on single species to complex, long-term studies that encompass interactions across interdependent species.
“Like any discipline, it takes it time to mature, and now we’re seeing that maturing process,” said Shallin Busch, who studies ocean acidification at the National Oceanic and Atmospheric Administration’s (NOAA) Northwest Fisheries Science Center in Seattle.
As the ocean absorbs carbon dioxide from the burning of fossil fuels, the pH of seawater falls. The resulting increase in acidity hinders the ability of coral, crabs, oysters, clams and other marine animals to form shells and skeletons made of calcium carbonate. While the greenhouse gas effect from pumping carbon dioxide into the atmosphere has been known for decades, it wasn’t until the mid-2000s that the impacts of ocean acidification became widely recognized. In fact, there is no mention of acidification in the first three reports from the United Nations Intergovernmental Panel on Climate Change, issued in 1990, 1995 and 2001. Ocean acidification did receive a brief mention in the 2007 report summarizing the then-current state of climate science, and finally was discussed at length in the latest edition released in 2014.
But about halfway through that brief dozen years of acidification research, a shift started taking place.
“The early studies were just a first step and often quite simple,” said Busch of ocean acidification research. “But you can’t jump into the deep end before you learn how to swim.”
That started to change about five or six years ago, according to Philip Munday, who researches acidification effects on coral reefs at Australia’s James Cook University. “The first studies were often single species tested against ocean acidification conditions, often quite extreme conditions over short periods of time,” he said. “Now people are working on co-occurring stresses in longer-term experiments.”
That includes studying how acidification could change how organisms across a community or ecosystem interact – in other words, how the impacts on one species affect those it eats, competes with or that eat it. It also means looking at how impacts could change over time, due to species migrating or adapting, either in the short term or across a number of generations and how such effects may vary within the same species or even with the same population.
Nine examples of this new generation of acidification research are included in the latest issue of the journal Biology Letters. One study, for example, found that the ability to adapt to pH changes differed in members of the same species of sea urchins based on location. Another discovered that a predatory cone snail was more active in waters with elevated carbon dioxide levels but was less successful at capturing prey, reducing predation on a conch species. Another highlights that an individual organism’s sex can affect its response to acidification.
Munday, who edited the series of papers, said one of the major takeaways is that researchers are increasingly studying the potential for species to adapt to ocean acidification and finding those adaptations can be quite complex.
He pointed to a study on oysters. Previous work had shown that oysters whose parents were exposed to acidification conditions do better in those conditions than those whose parents weren’t. But in a new study, researchers found that when they exposed the offspring to additional stressors – such as hotter water temperatures and higher salinity – those adaptive advantages decreased.
All the studies call for including often-overlooked factors such as sex, location or changes in predation rate in future studies. Otherwise, researchers warn, impacts will be increasingly difficult to predict as the ocean continues to acidify.
“It’s far too early to make any sort of generalities,” Munday said.
The latest paper from NOAA’s Busch also cautions against generalities. By building a database of species in Puget Sound and their sensitivity to changes in dissolved calcium carbonate, she found that summarizing species’ sensitivity by class or order rather than the specific family can result in overestimating their sensitivity.
She compared it to similarities between people in the same immediate family versus people who are distant cousins. “There would be a lot more variation among those people because they’re not super closely related,” she said. “But when people started summarizing data really early in the field, there wasn’t much data to pull from. So it was done at a class level.
“Now that we have many more studies and information to pull from, how we draw summaries of species response should be nuanced,” she added.
Acidification research is likely to get only more nuanced in the years ahead. From the broad initial projections of average, ocean-wide surface acidity, for instance, researchers have started to pinpoint local pH projections, local impacts and local adaptations.
“We know the ocean is changing in a number of ways,” said Busch. “So just studying one of those factors without looking at the other changes in what’s going on in the ocean is not going to yield useful results.”

How International Law Could Help Small Islands Tackle Climate Change

Oceans Deeply - Ian Evans

Small island states face increasing threats from climate change – from rising sea levels to the loss of coral reefs. University of Hawaii law professor Maxine Burkett discusses legal strategies that could help them secure compensation for those impacts.

Puerto Rico was devastated by Hurricane Maria. But for all of the damage, the island is at least a territory of one of the world’s richest and most powerful nations, the United States. Many island nations are not so lucky.
Small island states, such as Dominica or the Marshall Islands, are also feeling the impact of climate change, especially as it alters the ocean surrounding them. This means more than just storms and rising sea levels, says Maxine Burkett, a professor of law at the University of Hawaii at Manoa, who focuses on climate change law and policy. Climate change’s impact on the oceans affects the agriculture, infrastructure and even the psychology of the people on island nations. But they don’t have a large, powerful government to turn to for aid – instead, they are trying to highlight these issues on an international stage.
Oceans Deeply spoke with Burkett about how changing oceans are affecting small island states, and what legal actions, if any, they might take.

Oceans Deeply: Can you give us an idea of how small island nations are currently threatened by sea level rise?
Maxine Burkett: It depends on where you are. There are so many islands that we need to be thinking of – at least 43 are part of the Alliance of Small Island States, which are seeing coastal erosion. A number of small islands have major infrastructure on the coastline: airports, harbors, sewage treatment plants, etc.
You’re also seeing the impact, in the Pacific, of saltwater intrusion into arable lands, so food resources are being affected as well by sea level rise. When you’re looking at a number of islands in the Pacific, taro is a staple [food] and the introduction of saltwater into those areas makes it more difficult to grow taro. We’ve seen this happening in Micronesia and the Marshall Islands.
Of course, in somewhere like the Marshall Islands the impact on food security is not just from the inability to grow food, but also the quality of the reef. There is a lot of concern about the state of the reefs and that affecting primary food sources and fish as a major source of protein.
We think a lot about sea level rise for island nations, but of course there are additional risks that are, in some cases, more near-term, and that could be a lack of freshwater resources – especially for these Pacific island nations where they rely a lot on rainfall for freshwater. That is actually the near-term concern: freshwater and drought.
On islands, resilient infrastructure is needed to keep rising sea levels at bay. Some islands are turning to the international community to help pay for it. (Photo by Kees van der Geest, Environmental Law Program, University of Hawaii, courtesy of Maxine Burkett)
Oceans Deeply: You have written about residents of island nations that may soon have to leave their homelands because of these climate impacts. That must have a psychological impact, as well.
Burkett: That’s right. The notion, to quote a [fellow] researcher, that “their grandchildren will not grow old on the island,” has an impact on them quite deeply.
Ultimately, people don’t want to leave their home. So we’re in an interesting space right now where we have to contemplate the complete uninhabitability of some of these islands, but we also have to contemplate some major engineering feats to make sure that doesn’t happen and people can stay in place. It is a real struggle.

Oceans Deeply: One of your papers, “Rehabilitation: A Proposal for a Climate Compensation Mechanism for Small Island States,” focuses on possible legal strategies to deal with these issues: What does rehabilitation and compensation mean in this context?
Burkett: This is a paper that is really trying to address loss and damage. That is, finding legal avenues for responding to complete losses of things that cannot be resuscitated as a result of climate change, and [legal avenues] for damages that may be resuscitated, but as of yet we don’t have the proper legal avenues to resolve.
Island nations have been trying to introduce “loss and damages” into the framework of the Convention on Climate Change for a couple of decades – since the early ’90s. They noted that there are impacts of climate change that you can’t adapt to; that will be so severe that you’ll need additional resources to allow states to bounce back from those losses. There were [several] mechanisms that they sought to address it, [including] this notion of rehabilitation. [Terms like] “liability concerns” or “compensation” are really big red flags in international negotiations, so “rehabilitation” was meant to suggest that this is an opportunity to make whole, as much as possible, communities that have suffered losses.

Oceans Deeply: Are you referring to compensation in a purely monetary sense?
Burkett: It doesn’t have to be. That’s something that is to be determined. The paper is starting the exercise of asking the kinds of questions that we need to ask, which are: Who’s eligible? What kind of remedy would they be open to receiving? If this is monetary, who would be paying into this potential global pool of resources that could help communities that have suffered losses and damages? What are the events that trigger the need for these rehabilitation mechanisms? It’s an exercise in asking the question and attempting to answer, but not conclusively.

Oceans Deeply: We are seeing these dramatic impacts more and more—Barbuda, for instance, is now uninhabited due to Hurricane Irma. What steps can small island nations take right now?
Burkett: Herein lies the difficulty – it seems like there ought to be a number of legal remedies that they can take. But, of course, this is the international community, and so the kinds of appeals that you saw on the opening day of the [United Nations] General Assembly are probably the most forceful demands that can be made. [Demands like:] “We have suffered great losses. We are disproportionate contributors to the problems, and we are especially suffering from them. Recognizing that inconsistency, we request greater aid, or more committed effort to reducing emissions and supporting adaptation.” And then, really building on the loss and damage provision so that so that there can be a sound framework for responding to these disasters after they happen.
In the U.S. you can imagine a scenario in which you bring the emitters to court, or cite violations in terms of environmental integrity, but that’s not available in the international community. So, the short answer is, I don’t know that they have a clear path right now besides those political appeals at the international stage.
If the circumstances were reversed – if we in the U.S. were experiencing the impacts of climate change to the extent the islands are, we would have a very different approach to it, and even more so if we were not a major contributor to the problem. I think that we can see the inequity there, and it is important to name it.
The upside is, understanding our impact and understanding our responsibility is the first step in getting us to better results.
