The smoke from dozens of wildfires in the western United States is stretching clear across the country — and even pushing into Mexico, Canada and Europe. While the dangerous plumes are forcing people inside along the West Coast, residents thousands of miles away in the East are seeing unusually hazy skies and remarkable sunsets.The wildfires racing across tinder-dry landscape in California, Idaho, Oregon and Washington are extraordinary, but the long reach of their smoke isn’t unprecedented. While there are only small pockets in the southeastern U.S. that are haze free, experts say the smoke poses less of a health concern for those who are farther away.The sun was transformed into a perfect orange orb as it set over New York City on Tuesday. Photographs of it sinking behind the skyline and glinting through tree leaves flooded social media. On Wednesday, New Jersey residents described a yellow tinge to the overcast skies, and weather forecasters were kept busy explaining the phenomenon and making predictions as to how long the conditions would last.On the opposite coast, air quality conditions were among some of the worst ever recorded. Smoke cloaked the Golden Gate Bridge and left Portland and Seattle in an ashy fog, as crews have exhausted themselves trying to keep the flames from consuming more homes and even wider swaths of forest.Satellite images showed that smoke from the wildfires has traveled almost 5,000 miles (8,000 kilometers) to Britain and other parts of northern Europe, scientists said Wednesday.The current weather system, which favors a westerly wind across the higher levels of the atmosphere, is to blame for the reach of the smoke, experts explained.“We always seem, at times, to get the right combination of enough smoke and the upper level jet stream to line up to bring that across the country, so we’re just seeing this again,” said Matt Solum with the National Weather Service’s regional operations center in Salt Lake City, Utah. “It’s definitely not the first time this has happened.”There could be some easing of the haze this weekend as a storm system is expected to move into the Pacific Northwest and could affect the conditions that helped the smoke travel across the country. But Solum said there’s always a chance for more smoke and haze to shift around.“Just due to all the wildfires that are going on, this is likely going to continue for a while,” he said. “You might have ebbs and flows of that smoke just depending on how the upper level winds set up.”Kim Knowlton, a senior scientist with the Natural Resources Defense Council in New York City, said she woke up Wednesday to a red sunrise and more haze.She said millions of people who live beyond the flames can end up dealing with diminished air quality as it’s not uncommon for wildfire smoke to travel hundreds of miles.Although the health impacts are reduced the farther and higher into the atmosphere the smoke travels, Knowlton and her colleagues said the resulting haze can exacerbate existing problems like asthma and add to ozone pollution. 3070

The South Georgia Islands might not be permanently populated by humans, but it is an important sanctuary for penguins, seals and other various creatures in the South Atlantic.But a giant iceberg, A68a, could threaten the wildlife on the islands, according to the Government of South Georgia & the South Sandwich Islands.With the assistance of the Royal Air Force, the government has been tracking the iceberg’s movement toward the islands. While the islands do not have a permanent population, they are visited by tourists and others.According to the BBC, A68a was 150 kilometers from South Georgia. The concern is the iceberg could disrupt breeding for penguins on the island.“We are now entering the key part of the year for breeding," Mark Belchier, director of fisheries and environment for the government of South Georgia & the South Sandwich Islands, told BBC News."The nests have been built for gentoo penguins, and eggs will be laid soon. And the first seal pups have been born in the last fortnight," he added.The islands used to be populated on a more permanent basis as a small settlement ran a whaling station.Before air travel, the islands were used by explorers to prepare for treks to Antarctica. Whalers on the island also played a key role rescuing Sir Earnest Shackleton’s crew after his expedition became stranded on Antarctica’s Elephant Island. 1381

The Walt Disney Co. has “dramatically” slashed its advertising budget on Facebook and Facebook-owned Instagram, according to a report in the Wall Street Journal.It’s the latest setback for the social network, which is facing a growing advertising boycott over its policies and actions on hate speech on its platforms. The Journal, citing unnamed sources familiar with the matter, said the time frame for Disney’s pullback was not clear.Disney was Facebook’s biggest U.S. advertiser for the first six months of 2020, according to research firm Pathmatics Inc. Disney joins hundreds of other companies that have paused spending on the service. The report did not say whether Disney is officially joining the ad boycott. Some companies, such as Starbucks, are pulling back social media advertising due to hate speech and other concerns but have not officially joined the “Stop Hate for Profit” campaign.Representatives for Disney did not immediately respond to a Sunday message seeking comment.The economic fallout from the pandemic has also cut into companies’ advertising budgets.Facebook said it does not comment on individual advertisers. The company said in an emailed statement Sunday that it invests “billions of dollars each year to keep our community safe and continuously work with outside experts to review and update our policies.”“We know we have more work to do, and we’ll continue to work with civil rights groups, (the Global Alliance for Responsible Media coalition), and other experts to develop even more tools, technology and policies to continue this fight,” Facebook said. 1599

The service academy game between Air Force and Army scheduled for Saturday at West Point, New York, was postponed Thursday due to an increase in COVID-19 cases at the Air Force Academy and the surrounding community."We are disappointed to postpone this game, but the health and safety of our cadets, staff, and the community continues to be our No. 1 priority at the Academy," Air Force Falcons Director of Athletics Nathan Pine said in a press release. "Due to the upward trends in our COVID numbers across the campus, we have paused all intercollegiate team activities."The Falcons can win the Commander-in-Chief’s Trophy with a win over Army. Air Force began the round-robin competition between the service academies with a 40-7 win over Navy on Oct. 3.The winning academy goes to the White House to receive the coveted trophy from the President.According to The Athletic's Stewart Mandel, this marks the seventh college football game this week to be postponed or canceled due to COVID.The schools are working to reschedule the game. 1044

The U.S. surpassed 200,000 deaths linked to COVID-19 on Tuesday, according to a database kept by Johns Hopkins University.The deaths — all of which have occurred since February — out-total the number of Americans lost to World War I, the Korean War, the Vietnam War, the War in Afghanistan and the Iraq War combined.The 200,000 deaths are the most of any country around the world. Brazil currently ranks behind the U.S., with about 137,000 deaths.According to Johns Hopkins the U.S. also has among the highest COVID-19 mortality rates in the world. About 61 Americans per 100,000 have died of COVID-19. That ranks sixth in the world and in the company of countries like Spain (65.27) and Mexico (58.24)The U.S. also leads the world with 6.8 million confirmed cases of COVID-19. India (5.5 million), Brazil (4.5 million) and Russia (1.1 million) are the only other countries with at least 1 million confirmed cases of the virus.Johns Hopkins reports that daily confirmed cases of COVID-19 dropped throughout the month of August. However, case rates have ticked up throughout September, and top health experts like Dr. Anthony Fauci are bracing for a difficult winter.Earlier this month, Fauci warned that a wintertime surge could be possible as weather forces Americans indoors and cities begin relaxing COVID-19 lockdown restrictions. Health officials have warned that large indoor gatherings can result in COVID-19 superspreader events.The Institute for Health Metrics and Evaluation at the University of Washington — a model often used by the White House — currently projects that an additional 175,000 Americans will die of the virus by Jan. 1. That projection could drop to as little as 65,000 additional deaths with a universal mask mandate and could increase to as many as 225,000 additional deaths with easing restrictions. 1838
