Wildfires have ravaged the U.S. state of California, killing at least 5 people and forcing thousands to evacuate (leave) their homes. Fueled by a heat wave and sparked by lightning strikes, the wildfires have set the state ablaze and covered the air in thick smoke.

Wildfire is the uncontrolled burning of large areas of vegetation. Wildfires may be ignited by human activities or by natural causes. Such natural causes include lightning, volcanic activity, or even intense sunlight. Wildfires occur on every continent except Antarctica. They are most common in the temperate forests and grasslands midway between the equator and the poles. They are less common in tropical and desert ecosystems.

These are far from California’s deadliest wildfires. Numerous major wildfires occurred in California in the early 2000′s. In 2003, wildfires in southern California destroyed thousands of homes and killed more than 20 people. In 2007, deadly wildfires forced the evacuation of about 500,000 people in San Diego County. In 2013, the so-called Rim Fire burned large areas of the Stanislaus National Forest near Yosemite National Park. Some of the largest wildfires in California history burned during the summer of 2018.

The unhealthy air quality caused by the wildfires is especially concerning, because of the pandemic (global outbreak) of the respiratory disease COVID-19. Smoke-polluted air can weaken lung function, reducing the body’s ability to fight infection.

The current round of fires was made worse by an intense heat wave baking the American Southwest. On August 16, temperatures in California’s Death Valley reached 130 °F (54.4 °C). If these measurements are confirmed, they would be the hottest surface air temperatures ever recorded on Earth.

On August 4, two deadly explosions rocked Beirut, Lebanon. More than 100 people were killed, and thousands were injured. The blasts were compared in power to an earthquake, because people hundreds of miles or kilometers away felt the explosions.

No one knows exactly how the first blast occurred. It may have been caused by stored fireworks. The second explosion was likely caused by a highly explosive chemical called ammonium nitrate. There was a 2,750-ton (2,500-metric ton) stockpile of ammonium nitrate in a warehouse in the area, near the city’s port. The chemical is often used in fertilizer. Fertilizer is a substance that is added to soil to help plants grow.

Lebanon is a small country at the eastern end of the Mediterranean Sea and the western end of Asia. It has been a center of transportation and trade for over 100 years. Beirut is Lebanon’s capital and largest city. About half of the country’s people live in the Beirut area.

The blasts damaged many businesses and homes. Hundreds of thousands of people were displaced (forced to leave their homes). The devastation and destruction reminded many residents of the country’s decades-long civil war. A civil war takes place between people of the same country. Political differences between groups of Lebanese Christians and Muslims erupted into civil war in the mid-1970′s. Other rival groups also engaged in fighting. The conflicts caused much death, destruction, and damage to the country’s economy. A peace plan ended most of the fighting in 1991.

The explosions occurred while the entire world was struggling with the COVID-19 pandemic (global outbreak of disease). Hospitals that were reserved for patients suffering from coronavirus shifted to treating people injured by the blasts. In the explosion zone and elsewhere, people continued to search for missing friends, family, and others.

April 15, 2020

Today, April 15, is an important day on the calendar, and it is known for some momentous events in history. To many people in the United States, April 15 brings to mind taxes, as it is generally the final day income taxes can be filed with the Internal Revenue Service (IRS). Two other April 15 events do not brighten the mood: the U.S. President Abraham Lincoln died on that day in 1865; and the ocean liner Titanic sank on April 15, 1912. But a number of other events, including the births of the artists Henry James and Leonardo da Vinci and Jackie Robinson’s breaking the racial barrier in Major League Baseball (MLB), make April 15 a not altogether gloomy day.

On the evening of April 14, 1865, President Abraham Lincoln attended a performance of the comedy Our American Cousin at Ford’s Theatre in Washington, D.C. At 10:22 p.m., a shot rang through the crowded house. John Wilkes Booth, a Southern sympathizer and well-known actor, had shot the president in the head from the rear of the presidential box. Lincoln was carried unconscious to a boarding house across the street. The president died there at 7:22 a.m. on April 15.

Just before midnight on April 14, 1912, the British ocean liner RMS (Royal Mail Ship) Titanic struck an iceberg in the North Atlantic Ocean. The disaster occurred on the ship’s maiden (first) voyage from Southampton, England, to New York City. The ship struck the iceberg at about 11:40 p.m. and sank bout two and a half hours later, on April 15. The huge ocean liner broke in half and sank into the icy water, killing more than 1,500 people.

On Feb. 3, 1913, the Sixteenth Amendment to the Constitution of the United States authorized Congress to levy a federal income tax. The amendment allows Congress to levy an income tax on individuals and businesses without dividing it equally among the states or basing it on the U.S. census. The deadline for paying taxes from the previous year was originally March 1, and then March 15. In 1954, to give people a little more time to deal with the often complicated burden, the tax deadline settled on April 15.

On April 15, 1947, Jackie Robinson played his first game for the Brooklyn Dodgers, becoming the first African American to play in the major leagues since the 1880’s. Robinson’s impact on segregation in sports went far beyond the Dodgers. After baseball desegregated, other professional sports quickly followed, and a number of previously segregated hotels and restaurants began to admit blacks.

Aside from Leonardo da Vinci (1452) and Henry James (1843), notable April 15 birthdays include the U.S. painter Charles Willson Peale (1741); the U.S. Blues singer Bessie Smith (1894); the first African American mayor of Chicago, Harold Washington (1922); the Puerto Rican singer Luis Fonsi (1978); the Canadian-American actor Seth Rogan (1982); and the British actress Emma Watson (1990).

April 8, 2020

Today, April 8, Behind the Headlines was originally scheduled to cover this year’s National Collegiate Athletic Association (NCAA) basketball championships in the United States. However, the men’s and women’s NCAA tournaments were canceled in March because of the ongoing COVID-19 pandemic. The tournaments were not alone: nearly all sports leagues and sporting events have been suspended or canceled because of COVID-19, putting sports on hold in all corners of the globe. COVID-19 is a pneumonia-like disease caused by a coronavirus, a type of virus that also causes the common cold and other diseases of the upper respiratory system. To date, COVID-19 has killed more than 80,000 people among nearly 1.5 million confirmed cases.

All collegiate and high schools sports in the United States were suspended or canceled because of COVID-19 (the schools were then closed), and Little League Baseball, too, had to put off the start of its season. In professional sports, Major League Baseball, which had begun its annual spring training, canceled all exhibition games on March 12 and indefinitely delayed the start of the regular season. Minor League Baseball shut down, as did baseball leagues in Japan, Mexico, South Korea, and other countries. The National Basketball Association suspended its season on March 11, and basketball leagues in other countries were also shut down. The recently launched XFL football league suspended its first season on March 12, and the fledgling Basketball Africa League also lost its inaugural season, which had been scheduled to start on March 13.

Major League Soccer and the National Hockey League suspended their seasons in March, and other hockey and soccer leagues around the world were forced to do the same. Rugby and cricket leagues and tournaments were suspended, as were the upcoming Masters Tournament, PGA Championship, U.S. Open, and British Open golf competitions. In tennis, Wimbledon was canceled for the first time since World War II (1939-1945), and the French Open was postponed. The Kentucky Derby horse race and the Indianapolis 500 auto race were postponed, and the Monaco Gran Prix auto race was canceled. (All three races are usually run in May.) Marathons around the world have been canceled or postponed, and athletes of all types will have to wait for the Summer Olympic Games in Tokyo, which were postponed a year until July 2021.

Early in the COVID-19 pandemic, a number of sports continued to be played without fans in attendance, but fears for the safety of athletes quickly led to the canceling of the competitions themselves. Suspended and postponed sports leagues and events have issued optimistic timelines about when they will resume or take place. All timelines, however, depend on the containment or continued spread of COVID-19.

The sports cancellations are part of social distancing, also known as physical distancing, an effort to slow or stop the spread of a contagious disease by limiting contact between people. Social distancing is most effective against illnesses that can be transmitted by coughing or sneezing, direct or indirect physical contact, or through the air. Typical social distancing measures call for the closing of such public places as sports arenas, schools, restaurants, museums, and many offices and stores. They may also call for people to maintain a distance of around 6 feet (2 meters) between them in public places.

April 3, 2020

As the world continues to struggle with the ongoing COVID-19 pandemic, most schools and universities around the globe have closed in an effort to help stop the spread of the deadly disease. In the United States—where there are more COVID-19 cases (more than 245,000) than in any other country—school closures began in March 2020. Schools began to close in March or earlier in other countries as well, as COVID-19 quickly spread from where it was first detected, in China, in December 2019. COVID-19 is a pneumonia-like disease caused by a coronavirus, a type of virus that also causes the common cold and other diseases of the upper respiratory system. To date, COVID-19 has killed more than 54,000 people among more than 1 million confirmed cases.

According to the United Nations Educational, Scientific and Cultural Organization (UNESCO), 188 countries have closed schools locally or nationwide, leaving more than 1.5 billion people—nearly 90 percent of the world’s student population—out of classrooms. The closures have also affected more than 60 million teachers, many of whom continue to instruct through online classes or other forms of distance and remote learning.

Public schools are closed throughout the United States, but many states are hoping to bring students back to classrooms by the end of April. All timelines, however, depend on the containment or continued spread of COVID-19. Such states as Alabama, Oklahoma, and Virginia have cancelled classes until the start of the fall 2020 semester, and many other states may soon have to follow suit. As a result of the class disruptions, most standardized testing will not take place this spring, and the April ACT and May SAT college entrance examinations were both cancelled.

School closures are part of social distancing, also known as physical distancing, an effort to slow or stop the spread of a contagious disease by limiting contact between people. Social distancing is most effective against illnesses that can be transmitted by coughing or sneezing, direct or indirect physical contact, or through the air. Typical social distancing measures call for the closing of such public places as schools, restaurants, museums, and many offices and stores. They may also call for people to maintain a distance of around 6 feet (2 meters) between them in public places.

As the world struggles to deal with the ongoing COVID-19 pandemic, a practice called social distancing is being implemented to slow the spread of the disease. Social distancing describes the effort to limit direct human contact and increase the physical space between people to avoid spreading a contagious disease. Social distancing is most effective against illnesses that can be transmitted by coughing or sneezing, direct or indirect physical contact, or through the air. COVID-19 is a coronavirus that causes a pneumonia-like disease. Coronaviruses are types of viruses that cause the common cold and other diseases of the upper respiratory system.

Social distancing requires the limiting of non-essential travel and large group gatherings. Authorities have suggested keeping a distance of 6 feet (roughly 2 meters) from other people in public. Social distancing also calls for the closing of such public gathering places as schools, restaurants, museums, and many offices and stores. A widespread policy of social distancing to counteract COVID-19 began in many places the second week of March 2020.

Another aspect of the social distancing strategy requires that people who may have been exposed to a contagious disease isolate themselves, or self-quarantine. People in quarantine for COVID-19 must first follow the standard hygiene rule of washing their hands frequently. But they must also refrain from sharing towels or eating utensils, they must remain at home, they should not have visitors (except as needed to receive care), and they should follow the 6-feet (2-meter) distance rule with family members. Self-quarantine lasts for a period of at least two weeks. That amount of time allows people to know whether or not they have the coronavirus and if they are contagious to other people. After the period of self-quarantine, if the person does not show symptoms of COVID-19, they can return to their normal routine. For those that do have the coronavirus, they must then continue a longer period of isolation at home or in a hospital or other health care facility.

Social distancing can help flatten the curve, an expression that describes curbing of the rate at which people become infected by COVID-19. On a line graph, a sudden surge in cases of illness over a short time appears as a tall, narrow curve. On a similar graph, the same number of cases dispersed over a longer period of time appears as a longer, flatter curve. Ideally, social distancing will flatten the curve by slowing the numbers of people infected by COVID-19. Flattening the curve helps to avoid having more sick people than can be treated effectively at any one time.

COVID-19 is the name of a respiratory disease that was first recognized in human beings in the Chinese city of Wuhan in December 2019. The disease was given the temporary name 2019-nCoV, for novel (new) coronavirus of 2019. It was later officially named COVID-19. The virus that causes the disease was named SARS-CoV-2. Its symptoms include breathing difficulties, coughing, and fever. On March 11, 2020, The World Health Organization (WHO) declared COVID-19 a global pandemic—that is, a disease that has spread over an extremely wide geographic area. By mid-March, the virus had caused more than 8,200 deaths, and more than 200,000 cases had been confirmed worldwide. More than 150 countries have reported cases of COVID-19.

Tomorrow, March 21, marks 60 years since the Sharpeville Massacre took place in South Africa in 1960. On that day, South African police opened fire into a crowd of black demonstrators. The incident occurred in the township of Sharpeville, now part of the city of Vereeniging. The shooting left 69 people dead and more than 180 wounded.

The demonstration in Sharpeville was part of a nationwide protest against the pass laws. The pass laws required black adults to carry identity papers called passes. They also restricted the movement of black people around the country. The pass laws were part of a policy of rigid racial segregation called apartheid. The policy had existed in South Africa since 1948.

An antiapartheid group called the Pan Africanist Congress (PAC) organized the protest. The group called on black South Africans to go to police stations without their passes on March 21, 1960, and peacefully submit to arrest. Only a few demonstrators responded in most cities. In Sharpeville, however, several thousand protesters gathered outside the police station. A few hundred police officers faced them from behind a wire fence surrounding the station. In the early afternoon, the officers began to fire, probably in confused reaction to a scuffle between police and protesters near the fence. Many demonstrators were shot in the back as they fled.

The events at Sharpeville had long-lasting effects on the antiapartheid campaign. At first, the shooting sparked large demonstrations in sympathy for the victims. The government then banned the PAC and the African National Congress (ANC), a larger antiapartheid organization. Forced underground, the organizations altered their tactics to include violent forms of protest. Outrage over the deaths at Sharpeville also helped spur an international antiapartheid movement.

Apartheid ended in South Africa during the early 1990’s. Today, South Africans honor March 21, the anniversary of the Sharpeville Massacre, as Human Rights Day.

Earlier this month, on the night of March 2-3, massive thunderstorms spawned a cluster of tornadoes in Tennessee, killing 25 people and causing widespread destruction. The two most powerful tornadoes struck Nashville, the state capital, and nearby Putnam and Wilson counties. Tornadoes from the same storm system also touched the neighboring states of Alabama, Kentucky, and Missouri. Tennessee’s tornado outbreak was the worst since a group of more than 50 tornadoes killed 35 people in the state in April 2011.

Thunderstorms grew in size and intensity over Tennessee on March 2, and tornadoes were reported in eastern and northern parts of the state. Just after midnight, an EF3 strength twister hit downtown Nashville (in Davidson County) and quickly tracked eastward more than 60 miles (100 kilometers) into Wilson County. EF stands for the Enhanced Fujita scale, used to rate the strength of tornadoes. The scale rates tornadoes from 0, the weakest, to 5, the strongest. EF3 tornadoes have winds between 136 and 165 miles per hour (218 and 266 kilometers per hour) and can tear away roofs and walls from houses and overturn cars. An even stronger EF4 tornado—with winds up to 200 miles per hour (322 kilometers per hour)—then hit nearby Putnam County, but spared most of Cookeville, the county’s largest town. Of the 25 deaths from the Tennessee tornadoes, 18 of them occurred in Putnam County. Hundreds of people were injured in the storms, and numerous buildings were destroyed.

In the days after the storms, Tennessee Governor Bill Lee declared a state of emergency, and the Federal Emergency Management Agency (FEMA) provided millions of dollars in assistance to the hardest-hit areas. Schools, public offices, and interstate highways were closed for days in the region, and tens of thousands of people were without electric power.

On March 1, 1870, 150 years ago this Sunday, Paraguay’s President Francisco Solano López was killed by Brazilian troops in the Cerro Corá valley of northeastern Paraguay. López’s death marked the end of the War of the Triple Alliance (also called the Paraguayan War), the bloodiest war in Latin American history. The conflict had begun in 1864 and pitted Paraguay against the nearby nations of Argentina, Brazil, and Uruguay—the “Triple Alliance.” Paraguay lost the war, its population was decimated, and much of the country was destroyed.

It is a grim anniversary, but the War of the Triple Alliance still calls forth nationalistic pride in many Paraguayans. The country is marking the sesquicentennial of the end of the war with concerts, book launches, and conferences in Asunción, the capital, as well as special commemorations in the capital and at López’s death site along the Aquidabán Niguí River.

In 1862, as the United States struggled through a bloody Civil War, Paraguay’s first president, Carlos Antonio López, died after 21 years in power. His son, Francisco Solano López, then took over as a president with dictatorial powers. Francisco believed that Argentina and Brazil wished to occupy Paraguay and Uruguay, so he signed a defense treaty with Uruguay. In 1864, Paraguay went to war against Brazil to defend Uruguay’s government. After Argentina refused to let Paraguayan troops cross its territory to attack Brazil, López declared war on Argentina as well. In 1865, Brazil helped a new government take hold in Uruguay, which joined with Argentina and Brazil to form the Triple Alliance against Paraguay.

After initial Paraguayan victories, the turning point of the war came at the 1866 Battle of Tuyutí in southwestern Paraguay. In the bloodiest battle ever in South America, some 17,000 soldiers were killed at Tuyutí—most of them Paraguayan. A series of desperate battles followed as the Alliance armies gained the upper hand. By January 1869, Alliance troops had captured Asunción and controlled much of Paraguay, but López and a stalwart group of soldiers continued fighting a guerrilla campaign in the mountains. (Guerrilla warfare is conducted by roving bands of fighters who stage ambushes, sudden raids, and other small-scale attacks.) Brazilian troops eventually caught up with López and his remaining forces in the Cerro Corá valley, where the war ended with López’s death on the battlefield in 1870.

The war left Paraguay in ruins. Some historians estimate that the country lost about 60 percent of its prewar population, including nearly 90 percent of its men. In total, an estimated 400,000 people died in the conflict. Paraguay also lost a fourth of its territory. After the war, power struggles among rival political groups plagued the country. More than 30 presidents headed Paraguay’s government from 1870 to 1932.

Earth has been a particularly dangerous place in recent weeks. Airplane crashes, military clashes, terror attacks, and political unrest have taken a toll on human life and happiness lately, but it is a series of natural disasters that has caused the most trouble. A typhoon ravaged the Philippines, deadly flash floods hit Indonesia, bushfires continued to rage in Australia, a measles epidemic continued to kill in the Democratic Republic of the Congo, and a series of earthquakes rattled Puerto Rico.

On Christmas Eve and Christmas Day Typhoon Phanfone (also called Ursula) struck the Philippines, producing high winds and flooding that killed 105 people in the Visayan Island provinces of Biliran, Capiz, Iloilo, and Leyte. Phanfone was a Category 2 storm (moderate strength) with sustained winds of more than 90 miles (150 kilometers) per hour. Storm surges and deadly flash floods hit communities just as families were gathering to celebrate the Christmas holiday. Thousands of homes were damaged or destroyed.

On New Year’s Day in Indonesia, abnormally heavy monsoon rains caused flash floods that killed 66 people and displaced hundreds of thousands of others in Jakarta, the capital. Some 14.5 inches (37 centimeters) of rain fell on New Year’s Eve, causing the Ciliwung and Cisadane rivers to overflow. Floodwaters submerged more than 150 neighborhoods and caused landslides in the Bogor and Depok districts on the outskirts of Jakarta. Flood water levels in some areas peaked at more than 13 feet (4 meters). Electric power was cut off, and closed schools and government buildings were converted into emergency shelters.

On January 7, the World Health Organization announced the 6,000th death from measles in the Democratic Republic of the Congo (DRC) since an epidemic began there in 2019. More than 300,000 suspected measles cases have been reported in the DRC—a nation also troubled by recent terror attacks. The epidemic has continued and grown because of low vaccination coverage, malnutrition, weak public health systems, outbreaks of other epidemic-prone diseases (such as Ebola), and the difficulty of getting health care to people in remote areas.

In Puerto Rico, after several smaller earthquakes, a 6.4-magnitude temblor struck the southwestern part of the island on January 7. The earthquake, the strongest to hit Puerto Rico in more than 100 years, killed one person, toppled hundreds of structures, and forced a state of emergency. Many people lost their homes, the island briefly lost electric power, and schools and public offices were closed. In the 10 days before the 6.4-magnitude earthquake, the United States Geological Survey recorded hundreds of temblors in Puerto Rico—including 10 of 4-magnitude or greater.

A number of major bushfires have lately devastated southeastern Australia. Since September, the wild fires—mostly in New South Wales, Queensland, and Victoria—have burned more than 25.5 million acres (10.3 million hectares), an area the size of South Korea. The bushfires have destroyed more than 2,100 homes and killed 27 people and hundreds of millions of animals. On January 8, the Australian government ordered the mass slaughter of thousands of wild camels and horses that have invaded rural towns looking for water. Many people are without electric power and telecommunications in Australia’s southeast, and some were without drinking water and other supplies. Smoke has obscured the city skies of Canberra, Melbourne, and Sydney. The bushfires followed a three-year drought that experts link to climate change.
