Climate Crisis Gets 16 Minutes at Ninth Democratic Primary Debate in Las Vegas
The climate crisis got its moment in the sun during the ninth Democratic primary debate in Las Vegas Wednesday.
The six qualifying candidates discussed the issue for a full 16 minutes, Grist reported. The debate also marked the first time that a climate journalist was numbered among the moderators: Telemundo climate correspondent Vanessa Huac, who has covered environmental issues for more than 20 years.
"People in the United States and all over our planet are realizing that climate change is one of the most important issues of our times," Huac told NPR Tuesday ahead of the debate. "So, this is a great opportunity to really raise this issue and raise important questions to the candidates to see what are the plans, what are the proposals, how are they planning to face this existential crisis that we're facing."
This sense of public urgency around the issue is reflected in the pool of Nevadans who are likely to participate in the Democratic caucus Saturday. Eighty-six percent of them rated climate and the environment as very important or the most important issue of 2020, according to a League of Conservation Voters and Nevada Conservation League poll released last week. The poll also found that the issue came second to health care for most voters when deciding who to vote for. But for Latinx voters, who make up 20 percent of the Nevada voting block, climate was even more important than health care and immigration, InsideClimate News reported.

So how did the candidates address voters' concerns?
Wednesday's climate discussion was kicked off by Jon Ralston of the Nevada Independent, who pointed out that Reno and Las Vegas were among the fastest-warming cities in the country. He then directed his first question at former Vice President Joe Biden.
"What specific policies would you implement that would keep Las Vegas and Reno livable, but also not hurt those economies?" he asked, according to an NBC debate transcript.
Biden first focused on technical solutions, saying he would invest $47 billion in renewable energy and battery technology. He also said he would reverse President Donald Trump's environmental rollbacks and install 500,000 new electric vehicle charging stations in every highway his administration built or repaired.
"And I would invest in rail, in rail. Rail can take hundreds of thousands, millions of cars off the road if we have high-speed rail," Biden said.

Former New York City Mayor Michael Bloomberg, meanwhile, touted his success shuttering 304 of 530 coal plants in the U.S. as part of his Beyond Coal campaign with the Sierra Club. He also said he would rejoin the Paris agreement.
Senator Elizabeth Warren (D-Mass.) repeated her argument that addressing climate change requires addressing corruption in government.
"The first thing I want to do in Washington is pass my anti-corruption bill so that we can start making the changes we need to make on climate," she said. "And the second is the filibuster. If you're not willing to roll back the filibuster, then you're giving the fossil fuel industry a veto overall of the work that we need to do."
One major point of disagreement between the candidates was on whether or not to ban fracking.
Both Sen. Amy Klobuchar, (D-Minn.) and Bloomberg argued that natural gas is a "transitional fuel" between dirtier fuels like coal and renewable energy. Klobuchar said she would review every natural gas permit on a case-by-case basis and only approve them if they were safe. Bloomberg also said it was important to make sure natural gas extraction was done properly to not release excess methane. But he said it was not possible to abandon the fuel.
"We want to go to all renewables. But that's still many years from now," Bloomberg said.
Sen. Bernie Sanders (I-Vt.), on the other hand, has called for a fracking ban within the next five years, and addressed concerns that such a ban would hurt jobs. Sanders said the moment was too urgent not to act, and that the Green New Deal he supports would create as many as 20 million well-paying jobs.
"This is a moral issue, my friends. We have to take the responsibility of making sure that the planet we leave our children and grandchildren is a planet that is healthy and habitable," he said. "That is more important than the profits of the fossil fuel industry."
"We are fighting for the future of this planet," said @BernieSanders. "And the #GreenNewDeal, which I support by th… https://t.co/kTosBHGPCM— LCV – League of Conservation Voters (@LCV – League of Conservation Voters)1582170252.0
Also on the issue of jobs, Warren was challenged on her plan to ban mining and drilling on public lands, which is an important industry in Nevada. Public lands are also potential sources of minerals like lithium and copper necessary for renewable energy technology.
Warren said she would make an exception for minerals that are needed to transition away from fossil fuels.
"If we need to make exceptions because there are specific minerals that we've got to have access to, then we locate those and we do it not in a way that just is about the profits of giant industries, but in a way that is sustainable for the environment," she said.
Another point of disagreement was how to respond to China, which is currently the world's No. 1 emitter of greenhouse gases.
Bloomberg argued that it was important not to "go to war" with China on emissions but rather to negotiate.
"What you have to do is convince the Chinese that it is in their interest, as well. Their people are going to die just as our people are going to die. And we'll work together," he said.
But Former South Bend, Indiana Mayor Pete Buttigieg argued for the need for "hard tools" to ensure emissions fell worldwide.
"I'm a little skeptical of the idea that convincing is going to do the trick when it comes to working with China," he said. "America has repeatedly overestimated our ability to shape Chinese ambitions."
Both Biden and Warren, unprompted, raised the issue of environmental justice.
"[M]inority communities are the communities that are being most badly hurt by the way in which we deal with climate change," Biden said while answering a question about his plans to hold fossil fuel executives accountable for their pollution. "They are the ones that become the victims. That's where the asthma is, that's where the groundwater supply has been polluted. That's where, in fact, people, in fact, do not have the opportunity to be able to get away from everything from asbestos in the walls of our schools."
Warren later spoke up to "make sure that the question of environmental justice gets more than a glancing blow in this debate."

She touted her $1 trillion dollar plan to repair the environmental damage that had already been done to communities of color.
"We have to own up to our responsibility," she said. "We cannot simply talk about climate change in big, global terms. We need to talk about it in terms of rescuing the communities that have been damaged."

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>
