Australia Wildfire Forces 4,000 to Flee to Sea
An out-of-control wildfire in the Australian state of Victoria forced thousands of people to flee towards the coast Tuesday.
Residents of the town of Mallacoota hunkered down in their homes or headed for the relative safety of the beach when a siren sounded around 8 a.m., BBC News reported. Victoria's state emergency commissioner Andrew Crisp said 4,000 sheltered by the water.
"It's mayhem out there, it's armageddon," evacuee Charles Livingstone told The Guardian Australia. He said he had evacuated to the town's jetty Monday night with his wife and 18-month-old baby, but moved to the community center to escape the smoke.
The fire that prompted the flight to the coast sparked Sunday in Wingan, according to The Guardian, but CNN reported that there were more than 10 fires burning Monday in the East Gippsland area where Mallacoota is located. Three of those fires have been burning for more than a month, and several new blazes were started Sunday by dry lightning and then spread because of hot, dry, windy weather.
Mallacoota was not evacuated along with the rest of East Gippsland Sunday, and by Monday it was too dangerous for anyone to move, The Guardian explained.
Instead, residents fled to the water's edge, and the fire followed them around 1:30 p.m.

"It should have been daylight but it was black like midnight and we could hear the fire roaring," local business owner David Jeffrey told BBC News. "We were all terrified for our lives."
He said residents planned to jump off a sea wall into the water if the flames came too close.
Luckily, a change in the wind redirected the fire away from the town.
"I understand there was a public cheer down at the jetty when that was announced," chief fire service officer Steve Warrington told BBC News.
However, residents will now have to deal with fire damage. Warrington told CNN that "a number of houses" were destroyed or damaged. Mallacoota residents estimated on social media that around 20 homes, the school, golf club and bowling club had been burned, according to The Guardian.
"I just don't know how we're going to pull through this, really," Maisy Roberts, who works at the town's Croajingolong Cafe and thought her home was destroyed, told 3AW's Nick McCallum. "It's just absolute devastation."

Mallacoota is not the only place in Australia feeling the heat from a devastating fire season. Four people are missing in East Gippsland as a whole, 3AW reported. Initial aerial investigations show that 19 structures have been destroyed in Sarsfield and 24 in Buchanan, but authorities think the final tally for the region will be higher.
There are fires burning in every Australian state, CNN reported, though Victoria and New South Wales (NSW) have been the hardest hit. More than 900 homes have been destroyed in NSW alone.
Twelve people have died in the blazes so far, BBC News reported. On Tuesday, bodies believed to belong to a father and son were discovered in Corbargo, NSW.
Three of the dead were firefighters. Two, both fathers to young children, died in NSW a little less than two weeks ago. A third, 28-year-old Samuel McPaul, died Sunday when fire-created winds lifted his truck and flipped it over. He was newly married and expecting a child.
The fires have been linked to the climate crisis.
"Climate change is influencing the frequency and severity of dangerous bushfire conditions in Australia and other regions of the world," Australia's Bureau of Meteorology said, according to TIME.

Summer and fall are great seasons to enjoy the outdoors. But if you're already spending extra time outside because of the COVID-19 pandemic, you may be out of ideas on how to make fresh-air activities feel special. Here are a few suggestions to keep both adults and children entertained and educated in the months ahead, many of which can be done from the comfort of one's home or backyard.
The coronavirus may linger in the air in crowded indoor spaces, spreading from one person to the next, the World Health Organization acknowledged on Thursday, as The New York Times reported. The announcement came just days after 239 scientists wrote a letter urging the WHO to consider that the novel coronavirus is lingering in indoor spaces and infecting people, as EcoWatch reported.

It is undisputed that vitamin D plays a role everywhere in the body and performs important functions. A severe vitamin D deficiency, which can occur at a level of 12 nanograms per milliliter of blood or less, leads to severe and painful bone deformations known as rickets in infants and young children and osteomalacia in adults. Unfortunately, this is where the scientific consensus ends.
Where Does the Deficiency Begin?<p>Nobody knows exactly how much vitamin D a person actually needs. The question of when a deficiency starts is correspondingly controversial. However, vitamin D is becoming increasingly popular.Not only is the pseudo-scientific literature on the "sun vitamin" experiencing an upswing, but the number of published studies has also increased enormously in recent years. For example, in 2019 <a href="https://academic.oup.com/edrv/article/40/4/1109/5126915" target="_blank">a study found that</a> Vitamin D is responsible for keeping the skeleton functional and is associated with cardiovascular diseases, type 2 diabetes and various types of cancer. <br></p>
An All-Rounder<p>Vitamin D levels in the body rise and fall according to sun exposure. If sufficient UV rays reach the skin, the body is able to produce the vitamin itself. However, the human body only derives an estimated 10 to 20 percent of its daily requirement from food.</p><p>The vitamin D that we synthesize from sunlight or food is not biologically active at first. Before the kidneys can produce the biologically active form of the vitamin, known as calcitriol, and release it into the blood, some metabolic processes must take place beforehand.</p><p>In addition, many organs have receptors to which the precursor of calcitriol binds. Further, this substance is also present in blood.</p><p>From this precursor, the organs then produce calcitriol themselves, which the body then uses for countless other processes in the body. This form of vitamin D thus regulates insulin secretion, inhibits tumor growth, and promotes the formation of red blood cells as well as the survival and activity of macrophages, which are important for the <a href="https://www.mdpi.com/2072-6643/5/7/2502/htm" target="_blank">immune system.</a></p>
Low Vitamin D, Severe COVID-19 Disease?<p>A research study carried out <a href="https://www.sciencedirect.com/science/article/pii/S2352364620300067?via%3Dihub" target="_blank">at the University of Hohenheim</a> has now established a link between vitamin D deficiency, certain previous diseases, and severe cases of COVID-19.</p><p>According to the study, "there is a lot of evidence that several non-communicable diseases (high blood pressure, diabetes, cardiovascular diseases, metabolic syndrome) are associated with low vitamin D plasma levels. These comorbidities, together with the often accompanying vitamin D deficiency, increase the risk of severe COVID-19 events."</p><p>"This statement is completely correct," said Martin Fassnacht, head of endocrinology at the University Hospital of Würzburg. However, he qualifies that it is a pure association, "i.e. a mere observation that these events occur together.</p><p>Dr. Fassnacht is very critical of the hype surrounding vitamin D, but not because he denies the vitamin serves important functions. However, studies on humans have not been able to show that vitamin D has the healing powers many often propagate.</p><p>Fassnacht says, "If you take a closer look, the hopes that the administration of vitamin D has a healing effect have not been confirmed so far."</p>
Association Versus Intervention Studies<p>Many studies on the vitamin are association or observational studies. "By definition, these studies cannot prove the causal relationship, but only point to mere correlations," said Fassnacht. The physician tries to illustrate this with an example:</p><p>"Imagine two groups of 80-year-olds. One group is spry, active and does sports. If you compare them with another group living in nursing homes, the difference in vitamin D levels will be dramatic. Life expectancy would also be extremely different."</p><p>But to try to explain the difference in fitness by vitamin D status alone is far too simplistic. "Vitamin D levels are a good measure of how sick someone is. But not more," says Fassnacht. </p><p>According to Fassnacht, none of the intervention studies carried out to date -- that specifically examined the effect of vitamin D on various diseases -- has been able to confirm the previous association and laboratory studies or the presumed positive effect of vitamin D.</p>
Further Research Is Needed<p>"If a coronavirus infection is suspected, it is therefore absolutely necessary to check the vitamin D status and quickly correct any possible deficit," said the recommendation of the paper published by the University of Hohenheim.</p><p>"Studies are underway to see whether vitamin D helps in COVID-19 infection, but I personally do not believe that this is really the case," says endocrinologist Fassnacht. Nevertheless, he says it is of course useful to carry out these studies.<br></p><p>"I don't want to rule out that there are actually subgroups of people who benefit from an additional vitamin D dose," he says. After all, this has been proven to be the case with a severe deficit.</p><p>In view of the study situation, Fassnacht does not think much of preventive, nationwide vitamin D substitutes. "My belief that the vitamin helps somewhere is very low. But, of course, I can be wrong."</p>
