The pregame ceremony at Nationals Park on Thursday to start the 2020 MLB season was a reminder of several crises facing America in recent months.The pregame ceremonies started with leading infectious disease expert Dr. Anthony Fauci throwing the ceremonial first pitch in an empty Nationals Stadium, an indication that the 2020 season was disrupted by the coronavirus, which has claimed over 144,000 US lives. The MLB season started on Thursday, nearly 15 weeks later than scheduled.Fauci’s throw, which to his credit came from the stadium’s mound, bounced well wide of the plate.And then members of both the Yankees and Nationals took a knee in honor of the Black Lives Matter movement. The teams knelt while an audio clip was played by actor Morgan Freeman about social justice, a nod to the recent unrest in the wake of the death of George Floyd while in police custody.The game was the first official one played since last fall, when the Nationals won the 2019 World Series.As part of the pregame ceremony, the Nationals celebrated their World Series victory. 1071

The NAACP has filed a lawsuit against Postmaster General Louis DeJoy, claiming that he is attempting to "disenfranchise voters of color" amid the coronavirus pandemic.The lawsuit, filed Thursday in Washington, D.C. District Court, asks the court to declare DeJoy's recent operational changes as "invalid" and against the law as well prevent DeJoy from implementing further policy changes that were announced on July 10."As the country faces an uphill battle against COVID-19 and systemic racism, we're witnessing a significant onslaught against our postal system at a time when prompt mail delivery matters more than ever, especially for voters of color," Derrick Johnson, the President and CEO of the NAACP, said in a statement. "This willful and blatant attempt to obstruct the mail system amidst a pandemic and on the precipice of a pivotal election is a direct threat to the people of this nation's right to vote in a fair and free election."On Tuesday, DeJoy said in a statement that the USPS would pause the implementation of the proposed operational changes until after the November election. However, it's unclear if the agency would restore any mail sorting equipment that had been taken offline between the July 10 policy changes and Tuesday's statement.President Donald Trump has been staunchly opposed to universal mail-in voting, claiming that such policies would result in widespread voter fraud despite ample evidence to the contrary. Earlier this month, Trump said that he was hesitant to approve more funding for the USPS in order to curb the expansion of mail-in voting. 1596

The people of El Paso, Texas, are resilient. Living in the middle of the harsh Chihuahuan Desert, the city has no other choice. On average, 15 days every year spike over 100 degrees Fahrenheit. The city gets little relief with annual rainfall of just about 9 inches. It's one of the hottest cities in the country.One of its prime sources of water is the Rio Grande. Typically the river can supply as much as half of the city's water needs. But climate change is making that increasingly difficult and is pushing the city to look for new sources of water. Now, El Paso is on track to become the first large city in the United States to treat its sewage water and send it directly back into its taps.Increasing temperatures will make the dry region even more vulnerable to drought, according to the federal government's most recent national climate assessment. Already challenged with balancing the demands of about 700,000 thirsty El Pasoans along with agriculture and industry needs, El Paso must also face the fact that climate change is literally drying up one of its major sources of water.Analyzing tree ring records, scientists have been able to reconstruct the climate history of the region as far as the late 1500s and have found that as temperatures have risen, the amount of snow melting and feeding the Rio Grande has dropped."We're getting less runoff now than we would have gotten as recently as the '80s or '90s," said J. Phillip King, a professor of civil engineering at the University of New Mexico. King has tracked the river's water levels for the past 27 years as an adviser to the Elephant Butte Irrigation District. The district manages the water distribution of some 90,000 acres of farmland along the Rio Grande Valley in New Mexico and Texas.King told CNN Chief Medical Correspondent Dr. Sanjay Gupta that there is simply less snowmelt coming from northern New Mexico and southern Colorado to feed the river. Since 1958, the amount of early April snowmelt going into the Rio Grande has dropped 25% due to less snowpack and evaporation.What's happening in the Rio Grande is not unique. It's a phenomenon happening throughout the Western United States.King called the Rio Grande a harbinger of what's to come. "You know we've already gotten critically low here, and you can think of the Colorado as a few years away from a similar fate," he said.Drought isn't anything new for the 1,800-mile long river. The Rio Grande has survived severe and sustained droughts, King said. But an increase in temperature is pushing both a warmer and dryer climate. And that means not only potentially less snowfall but a greater chance for water to evaporate.The federal government projects that temperatures could rise an additional 8 degrees Fahrenheit in the region by 2100.The dwindling reserves are apparent at Elephant Butte Reservoir, just outside of Truth or Consequences, New Mexico. The reservoir there sits right on the Rio Grande and forms the largest recreational lake in the state. It holds water for farmers from north of El Paso up to Colorado. It has a capacity of about 2 million acre feet, King said. Currently, it's hovering around 3% to 4% of its full capacity. Buildings that were built as offices during the dam's construction in the early part of the 20th century were previously submerged in the 1980s. Now, they serve as lookout points to a nearly empty basin. 3399

  

The Indianapolis 500 will be held without fans in attendance on Aug. 23 due to escalating concerns over the coronavirus pandemic in Marion County, the Indianapolis Motor Speedway announced Tuesday.It will mark the first time in the 109-year history of the Indy 500 that it will be run in front of empty stands at the 2.5-mile oval track.“As dedicated as we were to running the race this year with 25 percent attendance at our large outdoor facility, even with meaningful and careful precautions implemented by the city and state, the COVID-19 trends in Marion County and Indiana have worsened," a news release from IMS said.First held in 1911, the Indianapolis 500 is the largest single-day sporting event in the world with approximately 350,000 people annually packing the track's grandstands and infield to watch "The Greatest Spectacle in Racing." Running the race without fans prevents the seventh cancellation in Indy 500 history. The race was not held in 1917-18 during World War I, and from 1942-45 during World War II.In late March, IMS leaders rescheduled the race from May 24 to Aug. 23. Officials said on June 26 that Indy 500 attendance would be limited to no more than 50%.That number was further decreased on July 22 when plans were scaled back to host the race at 25% capacity. Face coverings would be required, and the Speedway released an 88-page health and safety plan that provided guidelines and protocols for how the race would be run in 2020.Even at 25% capacity, the race would have been the largest event held in the United States since the beginning of the coronavirus pandemic.IndyCar and IMS owner Roger Penske previously said he wouldn't run the race without fans, but the realities of the pandemic prevailed.“We need to be safe and smart about this,” Penske told the Associated Press. “Obviously we want full attendance, but we don’t want to jeopardize the health and safety of our fans and the community. We also don’t want to jeopardize the ability to hold a successful race.”In a news release, IMS said in the weeks since the June 26 announcement of 50% capacity, the number of COVID-19 cases in Marion County has tripled while the positivity rate has doubled."We said from the beginning of the pandemic we would put the health and safety of our community first, and while hosting spectators at limited capacity with our robust plan in place was appropriate in late June, it is not the right path forward based on the current environment," the release said.How fans will be impactedThe announcement of no fans on race day also means all on-track activity during the month of August, including practice and qualifications, will be closed to the public. The first practice will take place on Aug. 12.Fans who still have tickets to the 2020 Indy 500 will be credited for the 2021 race and retain their seniority and originally assigned seats.Additionally, as announced in July, the race will be broadcast live on TV in Central Indiana for the first time since 2016.State and city leaders react to Speedway's decisionIndiana Gov. Eric Holcomb issued a statement following the announcement thanking Penske and IMS leadership and encouraging Hoosiers to do what they can to prevent the spread of COVID-19. 3239

  

The Mega Millions jackpot was a record-breaking .6 billion on oct. 23, and people across the country bought tickets in droves.Those behind the counter selling the lottery tickets say they heard it all from their customers.“If they win, they’ll buy us a new car or a new house,” said Francine Barela of promises she hears from customers at King Soopers in Denver, Colorado.Some people even promised to give a million dollars to the person who sold them the ticket.“You wonder are they really gonna come back? Are they gonna keep their word? But I don't really care whether they do,” Barela said. “Just be nice to know you sold the winning ticket!”Barela and co-worker Eva Bogue handle hundreds of tickets a day, but they rarely play themselves. That is until the jackpot is record-breaking.“The jackpots so big that you gotta take your chances with it,” Barela says.Would they keep their jobs?Bogue quickly replies, “No.” 940
