Democratic Candidates Face off on Climate in the Last Debate Before Primary Voting Begins
Six Democratic presidential candidates squared off Tuesday night in Des Moines, Iowa for the seventh primary debate of the season and the last before voting begins with the Iowa caucuses Feb. 3. The climate crisis tied with health care for the No. 1 issue important to Iowa voters when choosing a candidate, according to the latest Des Moines Register/CNN/Mediacom Iowa Poll. So how much attention did it get during the debate?
A fair amount, Grist reported. While CNN and Des Moines Register moderators didn't bring it up until the last half hour, the candidates themselves incorporated it into their answers early and often.
"Debate moderators may take ages to get around to climate change in these debates," Zoya Teirstein wrote for Grist, "but the candidates have gotten increasingly adept at weaving the issue into their answers to other questions. This time around, Wolf Blitzer, Abby Phillip, and the Register's Brianne Pfannenstiel could barely keep a lid on the climate action in the first half of the debate."

So how did the candidates stand on various climate-related issues?
The first climate mentions came in response to the first question, about which candidate was best prepared to be commander-in-chief.
Both former South Bend, Indiana Mayor Pete Buttigieg and Sen. Elizabeth Warren (D-Mass.) listed the climate crisis among new national security issues they would tackle as president, according to a transcript provided by the Des Moines Register.
Philanthropist Tom Steyer brought up the wildfires in Australia when asked how he would use military force as a president, suggesting that the climate crisis might require large international mobilizations.
"[T]here's a gigantic climate issue in Australia, which also requires the same kind of value-driven coalition-building that we actually should be using in the Middle East," he said.
The next time the candidates brought up climate was during the discussion of a new trade deal struck by President Donald Trump with Mexico and Canada. Sen. Bernie Sanders (I-Vt.) came out strongly against it, largely because it does not mention climate change.
"[E]very major environmental organization has said no to this new trade agreement because it does not even have the phrase 'climate change' in it. And given the fact that climate change is right now the greatest threat facing this planet, I will not vote for a trade agreement that does not incorporate very, very strong principles to significantly lower fossil fuel emissions in the world," he said.
Democratic lawmakers had pushed for a commitment to the Paris agreement to be included in the deal, but that did not make it into the final draft, The New York Times pointed out.
Sanders also fought back when Pfannenstiel tried to shift his answer from climate to trade more narrowly.
"Well, they are the same in this issue," he said, according to the transcript.
Steyer joined Sanders in saying that he would not sign the deal because it failed to mention climate.

The first question directly raised by the moderators about the climate crisis brought up last spring's disastrous flooding in the Midwest and focused on what candidates would do about farms and factories that could not be relocated.
The question first went to Buttigieg, who spoke generally about the need to act on climate until the moderators repeated the question.
"We are going to have to use federal funds to make sure that we are supporting those whose lives will inevitably be impacted further by the increased severity and the increased frequency," he said.
The question then went to Steyer.
"Look, what you're talking about is what's called managed retreat," Steyer answered. "It's basically saying we're going to have to move things because this crisis is out of control. And it's unbelievably expensive. And of course we'll come to the rescue of Americans who are in trouble."
Sen. Amy Klobuchar (D-Minn.) received some pushback from climate activists when she defended her decision not to call for an all-out ban on fracking.
"When it comes to the issue of fracking, I actually see natural gas as a transition fuel. It's a transition fuel to where we get to carbon neutral," Klobuchar said.
Her remarks come less than a week after a study found that new oil and gas emissions projected for the next five years could nearly cancel out the decline in coal emissions, partly enabled by the fracking boom and the falling price of natural gas.
"I cannot believe I am listening to @amyklobuchar talking about fracked gas as a bridge fuel in 2020," Sunrise Movement co-founder Varshini Prakash tweeted in response.

Over the course of the debate, the candidates attempted to position themselves as the best person to take on the climate crisis in office.
Steyer emphasized that climate was his top priority.
"And I'm still shocked that I'm the only person on this stage who will say this. I would declare a state of emergency on day one on climate," he said.
Warren, meanwhile, painted herself as the best person to get to the root cause of decades of climate inaction.
"Mr. Steyer talks about it being problem number one," she said. "Understand this, we have known about this climate crisis for decades. Back in the 1990s we were calling it global warming, but we knew what it was. Democrats and Republicans back then were working together because no one wanted a problem. But you know what happened? The industry came in and said, we can make big money if we keep them divided and make no change. Priority number one has to be taking back our government from the corruption. That is the only way we will make progress on climate, on gun safety, on health care, on all of the issues that matter to us."
Sanders, for his part, pointed to his plan for a Green New Deal to transition to 100 percent renewable energy in 10 years.
"If we as a nation do not transform our energy system away from fossil fuel, not by 2050, not by 2040, but unless we lead the world right now — not easy stuff— the planet we are leaving our kids will be uninhabitable and unhealthy," he said.
Former Vice President Joe Biden, meanwhile, pointed to his legacy.
"[B]ack in 1986, I introduced the first climate change bill — and check PolitiFacts (sic); they said it was a game-changer. I've been fighting this for a long time. I headed up the Recovery Act, which put more money into moving away from fossil fuels to — to solar and wind energy than ever has occurred in the history of America," he said.

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>
