Every Monday, Ricky Blanding drives his Ford Ranger pickup truck around Detroit along a carefully planned route. Blanding hops in and out of the truck, grabbing buckets of food scraps from porches and restaurants, piling those scraps into bins in the truck bed and driving them to a composting site. Blanding is the CEO of Scrap Soils, one of the many budding food waste collection services across the country helping to divert food from landfills and make composting more accessible. It’s especially important for those who can’t compost at home, who live in cities without municipal curbside pickup or who can’t get to a drop-off location. Composting leftover coffee grounds, eggshells, carrot tops and more reduces the amount of food that goes into dumps where it produces the potent greenhouse gas methane. It also ultimately helps create healthy soil for gardeners and urban farmers. Experts say companies like Scrap Soils are an important part of cleaning up the broader food ecosystem.

The spacecraft delivered materials and equipment for new research studies to the station.

Mud from a fjord shows an Atlantic air pattern brought wetter, colder spells to southern Greenland, a clue to how its ice may fare. Greenland’s ice is shrinking as the planet warms. But in the island’s southwest, rainfall and snowfall have been influenced by the same North Atlantic air-pressure pattern for at least 5,000 years. When that pattern tipped one way, the region turned wetter and colder. The record comes from mud on the floor of a Greenland fjord, and it suggests snowfall, not only temperature, shaped how the area’s ice grew and shrank. It doesn’t yet show how glaciers there will respond to the warming ahead. Johan Faust, a researcher at MARUM, the Center for Marine Environmental Sciences at the University of Bremen in Germany, led the work with colleagues in Germany, Norway, Denmark and Canada. A seesaw in the airThe pattern is called the North Atlantic Oscillation. It’s the difference in air pressure between a low that sits near Iceland and a high near the Azores, and it’s strongest in winter. When that difference is large, the pattern is in its positive phase. Northwestern Europe and southwestern Greenland both get more rain and snow.
