Obama Says 'Climate Change Can No Longer Be Ignored' as Jeb Bush Admits He's 'Concerned'
"2014 was the planet’s warmest year on record," said Obama. "Fourteen of the 15 hottest years on record have all fallen in the first 15 years of this century. This winter was cold in parts of our country—as some folks in Congress like to point out—but around the world, it was the warmest ever recorded."
"The fact that the climate is changing has very serious implications for the way we live now," he reminded us. "Stronger storms. Deeper droughts. Longer wildfire seasons. The world’s top climate scientists are warning us that a changing climate already affects the air our kids breathe. The Pentagon says that climate change poses immediate risks to our national security."
He boasted about the growth of wind power in the U.S., more fuel-efficient cars and more energy-efficient buildings. He touted some of the things his administration is already doing to address climate change, including his events last week on the health impacts of climate change.
But he called climate change "an issue that’s bigger and longer-lasting than my presidency."
"It’s about protecting our God-given natural wonders and the good jobs that rely on them," said Obama. "It’s about shielding our cities and our families from disaster and harm. It’s about keeping our kids healthy and safe. This is the only planet we’ve got. And years from now, I want to be able to look our children and grandchildren in the eye and tell them that we did everything we could to protect it."
He also announced that on Earth Day he will visit Everglades National Park "to talk about the way that climate change threatens our economy."
"The Everglades is one of the most special places in our country," he said. "But it’s also one of the most fragile. Rising sea levels are putting a national treasure—and an economic engine for the South Florida tourism industry—at risk."
Obama advisor Brian Deese revealed that during the week, the White House will be announcing natural landscapes to be targeted for conservation efforts, along with new funding to help farmers and ranchers reduce greenhouse gas emissions. It will also invite social media followers to submit photos of their favorite natural areas that are threatened by climate change.
“This Earth Day, we’re far beyond a debate about climate change’s existence,” said Deese. “We’re focused on mitigating its very real effects here at home, preparing our communities where its impacts are already being felt and leading an international effort for action.”
One Floridian who seems to be trying to stake out a position on climate change that will sound reasonable to most Americans yet align with the climate denial of many Republican primary voters is former Florida Governor Jeb Bush.
Joining the pack of 2016 presidential hopefuls in the early primary state of New Hampshire, Bush appeared to be trying to edge away from the full-throated climate deniers in the field like Ted Cruz and Rand Paul.
"The climate is changing, and I’m concerned about that," he said, before falling back on the false choice between addressing climate change and a strong economy. But he hasn't walked back on his statement that "It is not unanimous among scientists that it is disproportionately man-made,” technically accurate but misleading in light of the fact that 97 percent of scientists agree that climate-warming trends over the past century are very likely due to human activities. Bush embraces, as does President Obama, increasing natural gas extraction which has shown huge growth due to fracking.
And in February Bush told a meeting of the conservative Club for Growth that the Clean Air Act had "stifled the ability for people to rise up," and that the country's priority should be "growth at all cost." It seems that his "concern" for the climate only goes so far.

Fish exposed to endocrine-disrupting compounds pass on health problems to future generations, including deformities, reduced survival, and reproductive problems, according to a new study.
Low Levels Lead to Generational Impacts<p>Researchers exposed inland silverside fish to bifenthrin, levonorgestrel, ethinylestradiol, and trenbolone to levels currently found in waterways.</p><p>"Our concentrations were actually on the low end" of what is found in the wild, DeCourten said, adding that it was low amounts of chemicals in parts per trillion.</p><p>Bifenthrin is a pesticide; levonorgestrel and ethinylestradiol are synthetic hormones used in birth controls; and trenbolone is a synthetic steroid often given to cattle to bulk them up.</p><p>Such endocrine-disruptors have already been linked to a variety of health problems in directly exposed fish including altered growth, reduced survival, lowered egg production, skewed sex ratios, and negative impacts to immune systems. But what remains less clear is how the exposure may impact future generations.</p><p>For their study, DeCourten and colleagues started the exposure when the fish were embryos and continued it for 21 days.</p><p>They then tracked effects on the exposed fish, and the next two generations.</p>
Inherited Problems<p>DeCourten said the altered DNA methylation is one of the plausible ways that future generations would experience health impacts from previous generations' exposure. Hormone-disrupting compounds have been shown to impact DNA methylation, which is an important marker of how an organism will develop.</p><p>"Methyl groups are added to specific sites on the genome, [the exposure] is not changing the genome itself, but rather how the genome is expressed," she said. "And that can be inherited throughout generations."</p><p>In addition, Brander said there are essentially different "tags" that exist on DNA molecules, which tell genes how to turn on and off. She said the exposure to different compounds may be "influencing which methyl tags get taken on or off as you proceed through generations."</p><p>The researchers said the study should prompt future toxics testing to consider impacts on future generations.</p><p>"The results … throw a wrench in the current approach to regulating chemicals, where it's often short-term testing looking at simple things like growth, survival, and maybe gene expression," Brander said.</p><p>"These findings are telling us we really at least need to consider" the next two generations, she added.</p>

Consumers have long turned to vitamins and herbs to try to protect themselves from disease. This pandemic is no different — especially with headlines that scream "This supplement could save you from coronavirus."
Vitamin D<p><strong>What it is: </strong>Called "the sunshine vitamin" because the body makes it naturally in the presence of ultraviolet light, <a href="https://www.sciencenews.org/article/vitamin-d-supplements-lose-luster" target="_blank">Vitamin D is one of the most heavily studied</a> supplements (<em>SN: 1/27/19</em>). <a href="https://health.gov/our-work/food-nutrition/2015-2020-dietary-guidelines/guidelines/appendix-12/" target="_blank">Certain foods</a>, including fish and fortified milk products, are also high in the vitamin.</p><p><strong>Why it might help: </strong>Vitamin D is a hormone building block that helps strengthen the immune system.</p><p><strong>How it works for other infections:</strong> In 2017, the <em>British Medical Journal</em> published a meta-analysis that suggested a daily vitamin D supplement <a href="https://www.bmj.com/content/356/bmj.i6583" target="_blank">might help prevent respiratory infections</a>, particularly in people who are deficient in the vitamin.</p><p>But one key word here is <em>deficient. </em>That risk is highest during dark winters at high latitudes and among people with more color in their skin (melanin, a pigment that's higher in darker skin, inhibits the production of vitamin D).</p><p>"If you have enough vitamin D in your body, the evidence doesn't stack up to say that giving you more will make a real difference," says Susan Lanham-New, head of the Nutritional Sciences Department at the University of Surrey in England.</p><p>And taking too much can create new health problems, stressing certain internal organs and leading to a dangerously high calcium buildup in the blood. The recommended daily allowance for adults is 600 to 800 International Units per day, and the upper limit is considered to be 4,000 IUs per day.</p><p><strong>What we know about Vitamin D and COVID-19:</strong> Few studies have looked directly at whether vitamin D makes a difference in COVID.</p>
Zinc<p><strong>What it is: </strong>Zinc, a mineral found in cells all over the body, is found naturally in certain meats, beans and oysters.</p><p><strong>Why it might help: </strong>It plays several supportive roles in the immune system, which is why zinc lozenges are always hot sellers in cold and flu season. Zinc also helps with cell division and growth.</p><p><strong>How it works for other infections: </strong><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6457799/" target="_blank" rel="noopener noreferrer">Studies of using zinc for colds</a> — which are frequently caused by coronaviruses — suggest that using a supplement right after symptoms start might make them go away quicker. That said, a clinical trial from researchers in Finland and the United Kingdom, published in January in <em>BMJ Open</em> <a href="https://bmjopen.bmj.com/content/10/1/e031662" target="_blank" rel="noopener noreferrer">did not find any value for zinc lozenges</a> for the treatment of colds. Some researchers have theorized that inconsistencies in data for colds may be explained by varying amounts of zinc released in different lozenges.</p><p><strong>What we know about zinc and COVID-19:</strong> The mineral is promising enough that it was added to some early studies of hydroxychloroquine, a drug tested early in the pandemic. (Studies have since shown that <a href="https://www.sciencenews.org/article/covid-19-coronavirus-hydroxychloroquine-no-evidence-treatment" target="_blank">hydroxychloroquine can't prevent or treat COVID-19</a> (<em>SN: 8/2/20</em>).)</p>
Vitamin C<p><strong>What it is: </strong>Also called L-ascorbic acid, vitamin C has a long list of roles in the body. It's found naturally in fruits and vegetables, especially citrus, peppers and tomatoes.</p><p><strong>Why it might help:</strong> It's a potent antioxidant that's important for a healthy immune system and preventing inflammation.</p><p><strong>How it works for other infections: </strong>Thomas cautions that the data on vitamin C are often contradictory. One review from Chinese researchers, published in February in the <em>Journal of Medical Virolog</em>y, looked at <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/jmv.25707" target="_blank">what is already known about vitamin C</a> and other supplements that might have a role in COVID-19 treatment. Among other encouraging signs, human studies find a lower incidence of pneumonia among people taking vitamin C, "suggesting that vitamin C might prevent the susceptibility to lower respiratory tract infections under certain conditions."</p><p>But for preventing colds, a 2013 Cochrane review of 29 studies <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD000980.pub4/full" target="_blank" rel="noopener noreferrer">didn't support the idea</a> that vitamin C supplements could help in the general population. However, the authors wrote, given that vitamin C is cheap and safe, "it may be worthwhile for common cold patients to test on an individual basis whether therapeutic vitamin C is beneficial."</p><p><strong>What we know about Vitamin C and COVID-19: </strong>About a dozen studies are under way or planned to examine whether vitamin C added to coronavirus treatment helps with symptoms or survival, including Thomas' study at the Cleveland Clinic.</p><p>In a review published online in July in <em>Nutrition</em>, researchers from KU Leuven in Belgium concluded that the <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD000980.pub4/full" target="_blank" rel="noopener noreferrer">vitamin may help prevent infection</a> and tamp down the dangerous inflammatory reaction that can cause severe symptoms, based on what is known about how the nutrient works in the body.</p><p>Melissa Badowski, a pharmacist who specializes in viral infections at the University of Illinois at Chicago College of Pharmacy and colleague Sarah Michienzi published an extensive look at all supplements that might be useful in the coronavirus epidemic. There's <a href="https://www.drugsincontext.com/can-vitamins-and-or-supplements-provide-hope-against-coronavirus/" target="_blank" rel="noopener noreferrer">still not enough evidence to know whether they are helpful</a>, the pair concluded in July in <em>Drugs in Context</em>. "It's not really clear if it's going to benefit patients," Badowski says.</p><p>And while supplements are generally safe, she adds that nothing is risk free. The best way to avoid infection, she says, is still to follow the advice of epidemiologists and public health experts: "Wash your hands, wear a mask, stay six feet apart."</p>
