In some ways, thanks to the COVID-19 pandemic, Cyber Monday began weeks ago when online retailers began pushing holiday sales in mid-October. But forecasters are still projecting that Monday will be the biggest day of online sales ever recorded in the U.S.Online retailers are projected to sell .7 billion in goods on Monday, a figure that would represent year-to-year growth of 35%. Sales on Cyber Monday would outpace those made on both Thanksgiving and Black Friday.Several major retailers announced earlier this year that they would remain closed on Thanksgiving in the hopes of avoiding crowds, marking a stark change from recent years. In addition, the Associated Press reports that Black Friday crowds were thin across the country, as many Americans shopped online to avoid crowds. In fact, retailers like Walmart and Best Buy made Black Friday deals available online to limit the number of people in stores.However, Americans don't appear ready to slow down spending for Cyber Monday. Adobe Analytics predicts that Cyber Monday spending will break the billion for the first time in 2020. For context, the first time Americans spent billion on Cyber Monday came in 2012.Adobe also reports that 42% of online shopping will be done by smartphone this year — a year-over-year increase of 55%. 1314

In cities across America, volunteers stand armed and ready to fight a different kind of virus infecting the planet."Everything's changed right now. Everything is to-go, so it's turned into a disposable society again," said Miah Earn.Earn lives in Hillcrest, an urban neighborhood in San Diego, California. She's out on the streets cleaning up liter, protecting the city she's called home for over 30 years."It's a mess out here. It really is," said Earn. "I'm seeing masks and gloves everywhere. I don't understand why people can't hit the garbage with them."Ian Monahan is with I Love a Clean San Diego and says they've seen more trash in general during the pandemic. "Increased packaging, whether it's to-go containers, whether it's PPE, whether it's shipping products. Unfortunately, it's ending up on the streets, and we've got to protect it, so it doesn't get into the ocean or waterways at the end of the day," said Monahan. During a global clean-up event this month, Monahan says for the first time they'll be tracking the amount of PPE collected. "It's actually a whole new anomaly in our clean-ups. We really didn't see them before. And mostly it's the disposable masks, which people think are paper, they're actually plastic," said Monahan. Eventually, they will break down into microscopic pieces that will outlive us hundreds of years, and they can threaten wildlife and food supplies.Around the world, it's estimated nearly 200 billion disposable face coverings and gloves are being used each month because of the pandemic.The environmental conservation organization OceansAsia is documenting this new pandemic of pollution, capturing video of disposable face masks washing up on one of Hong Kong's most remote islands."Once you see this, you can't really unsee it," said Mitch Silverstein, chapter manager for Surfrider Foundation San Diego County.The nonprofit is piloting a program to make clean-ups more convenient, loaning the tools to businesses for the public to borrow. Volunteers have the option to fill out a data sheet with what they collected, which now includes PPE. Data collected around the world could help inform policy for products doing the most damage."Use reusable items, a reusable mask, reusable gloves when you're cleaning up," said Monahan. They say it will take a global shift in thinking to heal mother earth from what some call this human-made sickness. 2402

It took four days for The Associated Press and other media outlets to call the presidential election for Joe Biden and Kamala Harris. Now, recounts and certification of the results will take a bit longer.With races too close to call in Arizona, Nevada and Georgia, Pennsylvania became the battleground that tipped the Electoral College count in Biden’s favor Saturday afternoon.But within hours of declaring victory, President Donald Trump released a statement saying, “Joe Biden has not been certified the winner of any state.”“Technically it's true. Certifying election results takes a while,” said Kira Lerner, the managing editor of Vote Beat, a non-partisan, non-profit covering election administration and voting.“Canvassing is the process of counting the ballots,” said Lerner. “It's what election officials are doing across the country right now. They're working tirelessly, overnight in some cases, to make sure that every single vote is counted in the certification process. Each state has a different deadline.”Certification happens after canvassing – whereby election officials verify that every single ballot was counted and there were no clerical errors. But tallying has taken longer due to record turnout and a surge in mail-in ballots.Still, six states have a deadline of within one week of the election to certify their results and have already done so. (Delaware, Virginia, Vermont, South Dakota, Oklahoma, and Louisiana).In 26 states and Washington D.C., the certification deadline is between November 10 and the 30. (Wyoming, Mississippi, Florida, Massachusetts, Idaho, Arkansas, North Dakota, Georgia, Utah, Pennsylvania, Michigan, Maine, Kentucky, Ohio, North Carolina, New Mexico, Minnesota, Indiana, Washington D.C., Alaska, Alabama, Nebraska, Montana, Iowa, Colorado, and Arizona).In 14 states, the certification deadline is in December. (Wisconsin, Nevada, Kansas, West Virginia, Washington, Texas, Oregon, Connecticut, Illinois, New York, New Jersey, Missouri, Maryland, and California)The remaining states don’t have deadlines. (Hawaii, New Hampshire, Rhode Island, and Tennessee)“It will be some time before we can formally certify the winner of the presidential contest. But that doesn't mean that we won't know without a doubt who our president elect is, which we already do,” said Lerner.And then there are the recounts. In some states, they are automatically triggered when the victory falls within a razor thin margin. In Georgia, for example that’s .5%.But in the majority of states, candidates, political parties and in some cases voters can request a recount.Currently, the Trump administration is calling for recounts in Wisconsin and Georgia.“In Wisconsin, you have two days after the winner of the race has been certified to call for a recount. In other states, like Georgia, the secretary of state has already said that he will be seeking a recount on Donald Trump's behalf.”Lerner says legal challenges and recounts will likely fail to change the outcome of the election. Electors will vote by mid-December and deliver to officials in Washington just before Christmas. It may take a few more weeks but experts say the official results are unlikely to be delayed. 3213

INDIANAPOLIS -- An Indianapolis family is pleading for help to find the man they say broke into their home and ended up in bed with two little girls. Veronica Mildenberg says her 6-year-old and 10-year-old daughters were sleeping in the top bunk of her bed when the stranger climbed up with them.The 10-year-old woke up and screamed. “He must have climbed up the stairwell and got in bed with her. That’s when she hollered for her grandma,” Mildenberg said. “He woke her up because he touched her leg.”The surveillance video below shows the suspect peeking into the windows of the home on New York Street around 1:45 a.m. Minutes later, family members say he went to the back of the home and climbed through a kitchen window with a broken lock.   779

It's looking like at least one? — if not more — American tech giants may soon find themselves worth more than trillion dollars. That's a lot of zeroes. A dozen in fact.Apple is in the lead right now. Thanks to strong demand for its new iPhones, the company now has a market value of about 0 billion.The stock only needs to go up another 10% for Apple to top trillion.But even if Apple gets to the trillion dollar mark first, it may soon have company. Apple rival Alphabet -- aka Google -- has a market cap just shy of 0 billion.Amazon and Microsoft are also nipping at the heels of Apple and Google. Both of the Seattle-based tech titans are worth more than 0 billion.And these two companies seem to have more momentum than Apple and Google, whose stocks are up about 6% this year.In fact, GBH Insights analyst Daniel Ives wrote in a report Monday that he thinks Amazon could get to a trillion dollar valuation within 12 to 18 months.Amazon's stock has soared 30% this year thanks to impressive growth in its core e-commerce business as well as gains from last year's acquisition of Whole Foods and strength in its AWS cloud division.Microsoft has also benefited from growth in its cloud business. The stock is up 11% this year and is not far from a record high.If the four biggest tech companies all hit the trillion dollar milestone relatively soon, they eventually may wind up being joined by a few other tech giants -- and a much older school conglomerate as well.Facebook, Chinese e-commerce giant Alibaba and Chinese gaming and social networking kingpin Tencent are all worth about half a trillion dollars. So is Warren Buffett's Berkshire Hathaway.There's also the possibility that none of these tech companies will be the first to top the magical trillion dollar level.That's because oil giant Saudi Aramco is hoping to go public sometime this year -- and it is expected to be valued somewhere between .5 trillion and trillion. 1968
