4 Things You Need to Know As BP Gulf Oil Spill Trial Resumes
1. Phase two of the trial will cover how much oil BP actually discharged into the Gulf of Mexico as well as the effort to cap the well. (Remember the summer of “junk shots” and “top kills?”)
BP says the U.S. government’s estimate of 4.9 million barrels of oil is based on “faulty assumptions.” The company says they spilled only about 2.45 million barrels. BP’s estimate of a lower volume is based on the work of London-based professor Martin Blunt, who *ahem* used to work for BP. Either way, that’s a lot of oil, so why the fuss? Penalties for discharging oil—a violation of the Clean Water Act—are based on the amount of oil discharged. A lower volume means a lower penalty—potentially around $7 billion less.
2. BP agreed to a criminal settlement last fall that requires the company to pay approximately $4 billion in fines over a five-year period. One of the guilty pleas was for obstruction of Congress. In May 2010, BP officials told Congress that the company’s best estimate of the spill flow was about 5,000 barrels per day, even though BP’s own scientists said in company communications that it was likely much higher.
To put the penalty BP paid for all of their criminal counts in perspective, their profits for the fourth quarter of 2012 were $3.984 billion, down from $4.986 billion the year prior.
3. BP has launched a PR campaign designed to shore up the company’s assertion that they have “made it right” and to point fingers at Gulf residents, saying that many of the claims made as a result of losses incurred during the disaster are fraudulent and that the company has gone above and beyond in response and restoration. They took out full-page ads in several national newspapers asserting that they are being victimized.
The campaign moved into full swing during the month before phase two of the trial. According to The Hill, “Given that much of the advertising is in Washington, it may also be aimed at garnering political support to lessen pending Clean Water Act fines that are the subject of the ongoing federal trial.”
4. Despite ads to the contrary, there is still oil lurking in the Gulf of Mexico and on our coast. We are just now starting to see science on the impact of the spill in the marine environment, like this study of its effect on sediment in the Gulf. Organizations like the Gulf Restoration Network regularly find oiled shorelines on their patrols.
Ultimately, the amount of money available for restoration of the Gulf of Mexico via the RESTORE Act comes down to two things: How much oil did BP discharge, and were they grossly negligent in the actions leading up to and during the disaster? Let the facts, not a slick PR campaign, determine the fate of the Gulf of Mexico.

On his first day in office President Joe Biden started signing executive orders to reverse Trump administration policies. One sweeping directive calls for stronger action to protect public health and the environment and hold polluters accountable, including those who "disproportionately harm communities of color and low-income communities."
Michael S. Regan, President Biden's nominee to lead the U.S. Environmental Protection Agency, grew up near a coal-burning power plant in North Carolina and has pledged to "enact an environmental justice framework that empowers people in all communities." NCDEQ

Clear-cutting a forest is relatively easy—just pick a tree and start chopping. But there are benefits to more sophisticated forest management. One technique—which involves repeatedly harvesting smaller trees every 30 or so years but leaving an upper story of larger trees for longer periods (60, 90, or 120 years)—ensures a steady supply of both firewood and construction timber.
A Pattern in the Rings<p>The <a href="https://www.encyclopedia.com/science/dictionaries-thesauruses-pictures-and-press-releases/coppice-standards-0" target="_blank">coppice-with-standards</a> management practice produces a two-story forest, said <a href="https://www.researchgate.net/profile/Bernhard_Muigg" target="_blank">Bernhard Muigg</a>, a dendrochronologist at the University of Freiburg in Germany. "You have an upper story of single trees that are allowed to grow for several understory generations."</p><p>That arrangement imprints a characteristic tree ring pattern in a forest's upper story trees (the "standards"): thick rings indicative of heavy growth, which show up at regular intervals as the surrounding smaller trees are cut down. "The trees are growing faster," said Muigg. "You can really see it with your naked eye."</p><p>Muigg and his collaborators characterized that <a href="https://ltrr.arizona.edu/about/treerings" target="_blank">dendrochronological pattern</a> in 161 oak trees growing in central Germany, one of the few remaining sites in Europe with actively managed coppice-with-standards forests. They found up to nine cycles of heavy growth in the trees, the oldest of which was planted in 1761. The researchers then turned to a historical data set — more than 2,000 oak <a href="https://eos.org/articles/podcast-discovering-europes-history-through-its-timbers" target="_blank" rel="noopener noreferrer">timbers from buildings and archaeological sites</a> in Germany and France dating from between 300 and 2015 — to look for a similar pattern.</p>
A Gap of 500 Years<p>The team found wood with the characteristic coppice-with-standards tree ring pattern dating to as early as the 6th century. That was a surprise, Muigg and his colleagues concluded, because the first mention of this forest management practice in historical documents occurred only roughly 500 years later, in the 13th century.</p><p>It's probable that forest management practices were not well documented prior to the High Middle Ages (1000–1250), the researchers suggested. "Forests are mainly mentioned in the context of royal hunting interests or donations," said Muigg. Dendrochronological studies are particularly important because they can reveal information not captured by a sparse historical record, he added.</p><p>These results were <a href="https://www.nature.com/articles/s41598-020-78933-8" target="_blank">published in December in <em>Scientific Reports</em></a>.</p><p>"It's nice to see the longevity and the history of coppice-with-standards," said <a href="https://www.teagasc.ie/contact/staff-directory/s/ian-short/" target="_blank">Ian Short</a>, a forestry researcher at Teagasc, the Agriculture and Food Development Authority in Ireland, not involved in the research. This technique is valuable because it promotes conservation and habitat biodiversity, Short said. "In the next 10 or 20 years, I think we'll see more coppice-with-standards coming back into production."</p><p>In the future, Muigg and his collaborators hope to analyze a larger sample of historic timbers to trace how the coppice-with-standards practice spread throughout Europe. It will be interesting to understand where this technique originated and how it propagated, said Muigg, and there are plenty of old pieces of wood waiting to be analyzed. "There [are] tons of dendrochronological data."</p><p><em><a href="mailto:firstname.lastname@example.org" target="_blank" rel="noopener noreferrer">Katherine Kornei</a> is a freelance science journalist covering Earth and space science.

Earth's ice is melting 57 percent faster than in the 1990s and the world has lost more than 28 trillion tons of ice since 1994, research published Monday in The Cryosphere shows.
