Day two of the Trump era, environmentalists set their sights on … holiday cups.

Protestors with forest advocacy group Stand erected a giant, cardinal-red coffee cup in Seattle’s Westlake Center on Thursday, pressuring Starbucks to make its holiday cups recyclable.

Starbucks has struggled with reinventing its disposable products for years. It aimed to make all of its cups reusable or recyclable by 2015, but that hasn’t happened yet.

The night before, Westlake Center had been the site of a large protest against Donald Trump, who promises to gut existing measures to fight climate change.

So why focus on cups? Stand’s U.S. Campaign Director Ross Hammond told us: “Where we can make change is forcing companies to do things they should be doing but don’t want to do.”

Patrons of the original Starbucks store in Pike Place Market — a few blocks from the protest — had a different take:

“I don’t know how we can go from the [Trump] protests last night … to protesting red cups,” said Steph K., 28, of Los Angeles. We have a national identity crisis, she said, and “this is what we’re talking about?”

Starbucks told Grist that it is “committed to reducing the impact of waste generated in our stores,” and that its cups are recyclable in some places, like Seattle, already.

The Mystery of the Solar System’s Weirdest Moon, Explained

The first and only space probe ever to visit the planet Uranus timed its encounter very badly from a public-relations perspective. Voyager 2 zipped past the Solar System’s seventh planet on Jan. 24, 1986; four days later, the shuttle Challenger exploded in flames. And suddenly, far-off Uranus and its retinue of moons didn’t seem so important any more. Yet the images Voyager took during that overshadowed encounter have continued to intrigue planetary scientists ever since—and that’s especially true when it comes to Miranda, one of the planet’s five main moons. Its surface, U.S. Geological Survey astrogeologist Laurence Soderblom told TIME shortly after the encounter, “is a bizarre hybrid,” while NASA describes Miranda as having “one of the strangest and most varied landscapes among extraterrestrial bodies.” Perhaps the strangest features of all are Miranda’s three visible “coronae”—relatively crater-free regions marked by ridges and valleys and slapped onto the surface “like mismatched patches on a moth-eaten coat,” in NASA’s words. But now, nearly three decades after they were found, Miranda’s coronae may have an explanation at last. Writing in the journal Geology, Brown University planetary scientists Noah Hammond and Amy Barr argue that these odd scraps of terrain come from ancient hotspots in the moon’s 100-mile-thick crust of ice. “Despite being incredible cold,” says Hammond, ” there’s a lot of geologic activity on this moon.” Geology on the frigid moons of the outer Solar System itself isn’t such big news these days. Scientists have spotted volcanoes on Jupiter’s moon Io, ice geysers on Saturn’s moon Enceladus, lakes on Titan, plate tectonics on Europa and more. But to have geology, you need some source of heat, and there just doesn’t seem to be one for Miranda, which is deep-frozen to about -350°F. There’s no heat source now, anyway. But Miranda’s orbit is unusually tilted with respect to Uranus’ equator—its “inclination,” as astronomers call it, is about ten times greater than that of the planet’s other major moons. One way that could have come about is if Miranda’s orbit was originally very eccentric, or elongated. That would brought it into close encounters with other moons, which could have relocated into a tilted orbit. If Miranda’s orbit really was elongated, the moon would have been squeezed and stretched by the tidal effect of Uranus’ gravity, and, just like a rubber ball squeezed in your hand, it would have heated up a bit. And that rising heat would have made the ice itself flow very, very slowly upward—a process physicists call convection. Hammond and Barr created a computer model of that flow, and sure enough, he says, “we were able to show that if shell is convecting, it naturally produces four upwellings.” Since it’s just a model, it can’t simulate the actual moon precisely, but it’s definitely in the ballpark of what Voyager saw. Each upwelling of ice would have tried to spread as it reached the surface, and crinkled, accordion-fashion, into the ridges and valleys that characterize the coronae. The fact that these regions are relatively crater-free fits right in: new ice flowing out from the interior would have to sit on the surface for a long time to match the cratering of the surrounding areas. The coronae can’t be more than a few hundred million years old—peanuts compared with the rest of the surface, which dates back billions of years, and consistent, Hammond says, with the fact that Miranda probably gained its tilt and lost its heat generation about that long ago. It all hangs together—but since it’s based on a handful of images taken nearly 29 years ago that only show Miranda’s southern hemisphere, it may be hard to be proved definitively. Planetary scientists have a far richer set of observations for the moons of Jupiter and Saturn, where the Galileo and Cassini probes respectively stuck around snapping photos for years rather than flying by (and Cassini is still going strong). Unfortunately, while scientists are contemplating return missions to Jupiter and Saturn, nobody’s got plans to revisit Uranus. Which leaves Hammond and Barr’s theory of where the coronae came from in the “convincing but not definitive” realm. Hammond is absolutely definitive about one thing, however. “Miranda,” he says, “is a really cool moon.” […]

Tom Zeller Jr.: Energy Wars And Energy Revolutions: Michael Levi’s ‘The Power Surge’

Describing the contentious and often contradictory battle over energy policy in the United States, Allen L. Hammond, writing for The New York Times, noted: The contention is not just over specific elements of technology. The two sides differ over whether energy salvation lies in conservation or expanded production; in renewable or depletable energy resources; and in small-scale, decentralized energy sources or in large, centralized systems. If you’ve spent any amount of time staking out a position of your own on the nagging energy debates that have so polarized the nation of late — hydraulic fracturing, or fracking; nuclear power; renewables; shale oil; tar sands; coal — you’d be forgiven for thinking Hammond’s observation was a recent one. It was, in fact, published more than 35 years ago, and it is one of the many precious nuggets of insight unearthed by Michael A. Levi in his new book, The Power Surge: Energy, Opportunity, and the Battle for America’s Future. “Energy needs to be tackled more on its own merits,” Levi says, “and less as a way of sending signals about ideological positions.” Levi, a senior fellow for energy and environment at the Council on Foreign Relations and one of the country’s most pragmatic energy experts, combines a researcher’s analytical detachment with a journalist’s flair for on-the-ground storytelling to take ordinary readers into the impassioned and often ideologically warped debate over how best to keep the nation — and the world — industrious, comfortable, mobile and well lighted. It’s a place where politics, economics and technological derring-do collide to produce what are often unexpected — and perhaps even unwelcome — outcomes, and where discussions of American energy policy in particular long ago became stylized stand-ins for larger political and philosophical disagreements. Today, Levi explains, rapid and revolutionary changes in the nation’s energy portfolio are once again afoot: • Vast new stores of previously inaccessible or economically prohibitive oil and gas are positioning the U.S […]
