The Defense Department will install solar panels on the Pentagon, part of the Biden administration's plan to promote clean energy and "reestablish the federal government as a sustainability leader."

The Pentagon is one of 31 government sites that are receiving $104 million in Energy Department grants that are expected to double the amount of carbon-free electricity at federal facilities and create 27 megawatts of clean-energy capacity while leveraging more than $361 million in private investment, the Energy Department said.

Heavy snow and freezing rain hit parts of northern and central Europe on Wednesday, bringing transport to a halt in some Scandinavian regions and causing major disruption at airports in Frankfurt and Oslo.

At Frankfurt Airport, Germany's busiest, freezing rain forced a halt to takeoffs, German news agency dpa reported. The airport cited a danger of de-iced aircraft icing up again as they taxied toward the runway. Some departures resumed in the afternoon as the rain subsided. Hundreds of flights already had been canceled.

Tambor Lyngdoh made his way through the fern-covered woodland — naming plants, trees, flowers, even stones — as if he were paying older family members a visit.

The community leader and entrepreneur was a little boy when his uncle brought him here and said these words: "This forest is your mother."

Sacred forests and groves are primeval woodlands that different faith communities around the world have safeguarded for centuries as abodes of the spiritual or the divine.

Thousands of sacred forests have survived. They're the church forests in Ethiopia's highlands, hillside groves considered holy by Catholics in Italy, woodlands revered by Shinto practitioners in Japan and Indigenous people in Siberia, Australia, the Americas and India.

Parts of the Pacific Northwest were under an ice storm warning through Wednesday morning, threatening to add to the damage brought by a powerful winter storm that hit the region over the weekend.

Area of southwest Washington and western Oregon — including that state's largest cities of Portland, Salem and Eugene — were expecting to see a quarter-inch to an inch (6 to 25 millimeters) of ice, while freezing rain was forecast in the Seattle area.

Heavy snowfall and freezing rain across Germany on Wednesday caused the cancellation of hundreds of flights and trains, crashes on icy roads and school closures.

At Frankfurt airport, Germany's biggest, more than 500 flights were canceled, while in Munich over 250 arrivals and departures were canceled. In western Germany, Saarbruecken airport closed for the day, and Duesseldorf and Cologne/Bonn airports were also affected by delays and cancellations.

Dangerously cold temperatures affected much of the Rockies, Great Plains and Midwest on Tuesday, with wind chills below minus 30 degrees (minus 34.4 Celsius) in many parts of the central U.S.

More than 85,000 U.S. homes and businesses were without power early Tuesday, the bulk of them in Oregon after widespread outages that started Saturday. Portland General Electric warned that the threat of freezing rain Tuesday could delay restoration efforts. Transportation officials urged residents to avoid travel as roads were expected to be hazardously slick with ice that could weigh down trees and power lines, causing them to fall.

Rescuers evacuated tourists on Tuesday from a remote skiing area in northwestern China where dozens of avalanches triggered by heavy snow have trapped more than 1,000 people for a week, state media said.

The avalanches have blocked roads, stranding both tourists and residents in a village in Altay prefecture in the Xinjiang region, close to China's border with Mongolia, Russia and Kazakhstan.

The latest calculations from several science agencies showing Earth obliterated global heat records last year may seem scary. But scientists worry that what's behind those numbers could be even worse.

The Associated Press asked more than three dozen scientists in interviews and emails what the smashed records mean. Most said they fear acceleration of climate change that is already right at the edge of the 1.5 degrees Celsius (2.7 Fahrenheit) increase since pre-industrial times that nations had hoped to stay within.

A dangerous Arctic blast will continue sweeping across the U.S. on Monday and linger through at least midweek, prolonging a bitter cold that set record-low temperatures in parts of the country and threatens to further disrupt daily life, including an NFL playoff game and the first-in-the-nation presidential nominating contest in Iowa.

The National Weather Service said wind chills are expected to push temperatures 30 degrees below zero from the Northern Rockies to northern Kansas and into Iowa, testing the hardiness of caucus goers willing to brave the deep chill on Monday.
