Burning Less Coal = 19% Less Mercury in the Tuna You Eat

I couldn't, post-election, muster a plausibly big enough piece of good news to warrant a Thanksgiving blog—but then this morning one arrived. In an astonishingly short eight years, as a result of tougher emission rules on power plants and a declining use of coal, concentrations of mercury in Atlantic Bluefin tuna, the sushi sort, dropped by 19 percent.

There are similar findings for bluefish, but tuna are much longer lived, so the results are extremely surprising—concentrations of mercury in even much older tuna fell at the same or faster rate as mercury concentrations in sea water, suggesting that fisheries contamination can be reversed far more quickly than anyone had dreamed.

Bluefin tuna are still not healthy for women of child-bearing age—and most of the tuna which had led more than 10 percent of U.S. women having unhealthy mercury in their blood is not from the Atlantic ocean, which is healing, but from the Pacific, where coal consumption and mercury loading remains unabated.

Mercury contamination is a serious public health issue. In the U.S. alone, hundreds of thousands of newborns are at risk of lower IQ's from the mercury burden they are born with. Concentrations of mercury have been coming down as a result of broad public education and advisories on which fish to avoid. Overall, mercury emissions in the U.S. have declined sharply as a result of U.S. Environmental Protection Agency regulation.

Now the news from the North Atlantic suggests that globally the epidemic of mercury poisoning can be reversed far more rapidly than scientists had imagined. Requiring the clean up of coal power plant emissions in Asia, the globe's largest remaining source of mercury pollution, will begin to allow Pacific ocean fisheries to recover as well. It's important that countries considering the economics of building coal factor in the almost certain necessity to control for mercury—and when they do, they are likely to find that coal power is no longer economically competitive, so that not only will current plants reduce their emissions, but fewer new ones will make any kind of economic sense—which will be wonderful news for the communities where coal is mined and burned, as well as the climate.

More fundamentally, the North Atlantic story goes at the heart of the popular version of climate denialism—which is the initially plausible notion that the world is so large and each human so small, that it's just not likely that anything each of us does can really change the climate—or poison the oceans. And if we have, it's so terrifying that we really don't believe we can do anything about it. Isn't it too late?

What the declining mercury level in Bluefin tuna shows is that we can—and have—had enormous impacts on the natural world, but that we can, and are, reversing those impacts. Nature, if we stop abusing her, can heal herself not in centuries or even decades, but mere years—even the length of the U.S. president's term.

This is a good news story we need to tell everyone.

Video Shows Oil Company's Plans to Drill Arctic From Artificial Island

The Liberty Project has posted a video about its proposal to build the nation's first oil production platform in federal waters in the Arctic.

The video was quietly uploaded two months ago and shows Hilcorp Alaska's plan to build an artificial gravel island and undersea pipeline for its offshore drilling project in the Beaufort Sea. Frankly speaking, the five-minute clip—with its all-American voiceover and electric guitar riffs—is something you'd expect from a pickup truck commercial.

Scientists Discover Sea Levels Rose in Sharp Bursts During Last Warming

By Rice University

Scientists from Rice University and Texas A&M University-Corpus Christi's Harte Research Institute for Gulf of Mexico Studies have discovered that Earth's sea level did not rise steadily but rather in sharp, punctuated bursts when the planet's glaciers melted during the period of global warming at the close of the last ice age. The researchers found fossil evidence in drowned reefs offshore Texas that showed sea level rose in several bursts ranging in length from a few decades to one century.

The findings appeared Wednesday in Nature Communications.

Quitting Coal: New Global Survey Names the Companies, Countries and Cities

More than a quarter of the 1,675 companies that owned or developed coal-fired power capacity since 2010 have entirely left the coal power business, according to new research from CoalSwarm and Greenpeace. This represents nearly 370 large coal-fired power plants—enough to power around six United Kingdoms—and equivalent to nearly half a trillion dollars in assets retired or not developed.

While many generating companies go through this rapid makeover, the research also shows that a total of 23 countries, states and cities will have either phased out coal-fired power plants or set a timeline to do so by 2030.

New Evidence Suggests Ancient Egypt Was Brought Down By Volcanoes and Climate Change

Ancient Egypt is often described as an exotic place—pyramids, hieroglyphics, lavishly worshipped kings and queens.

But in many ways, it has a lot of parallels to modern life. It was an economically diverse, culturally vibrant and unequal place.

The millenniums-old society also struggled with a phenomenon that people today know all too well: climate change. And it may have ultimately led to the civilization's demise, according to a new paper by a team of researchers at Yale University.

The team of researchers studied the tail-end of ancient Egypt during the Ptolemaic dynasty between 305-30 BCE.

Kids Harmed by Portugal Fires Reach Key Crowdfunding Goal for Climate Lawsuit

As Portugal reels from its worst wildfires on record, seven Portuguese children have met an important crowdfunding goal for their major climate lawsuit against 47 European nations.

More than £20,000 ($26,400) was pledged by 589 people, allowing the Global Legal Action Network (GLAN)—the nonprofit coordinating the lawsuit—to identify and compile evidence to present to the European Court of Human Rights in Strasbourg, France. GLAN now has a new stretch target of £100,000.

German Nature Reserves Have Lost More Than 75% of Flying Insects

A new study published Wednesday in the journal PLOS ONE adds more evidence that insect populations around the globe are in perilous decline.

For the study, researchers from Radboud University in the Netherlands, alongside their German and English colleagues, measured the biomass of trapped flying insects at 63 nature preserves in Germany since 1989. They were shocked to discover that the total biomass decreased dramatically over the 27 years of the study, with a seasonal decline of 76 percent and mid-summer decline of 82 percent, when insect numbers tend to peak.

Pushing Toxic Chemicals and Climate Denial: The Dark Money-Funded Independent Women’s Forum

By Stacy Malkan

The Independent Women's Forum is a 501(c)(3) nonprofit that has taken money from tobacco and oil companies, partners with Monsanto, defends toxic chemicals in food and consumer products, denies climate science and argues against laws that would curb the power of corporations.

IWF began in 1991 as an effort to defend now Supreme Court Justice (and former Monsanto attorney) Clarence Thomas as he faced sexual harassment charges. The group now says it seeks to "improve the lives of Americans by increasing the number of women who value free markets and personal liberty."

Toxic Toys? After Nine Years, a Ban on Harmful Chemicals Becomes Official

Phthalates are a particularly harmful type of chemical, used, among a range of other ways, to soften plastic in children's toys and products like pacifiers and teething rings. In response to mounting concern about the serious health impacts of phthalates—most notably, interference with hormone production and reproductive development in young children—Congress voted overwhelmingly in 2008 to outlaw the use of a few phthalates in these products and ordered the Consumer Product Safety Commission (CPSC) to assess the use of other types of the chemical in these products. After much delay, the CPSC voted 3–2 Wednesday to ban five additional types of phthalates in kids' toys and childcare products.
