U.S. Shale Gas Production Could Sharply Decline in 2016, World Bank Says
In the wake of tumbling oil prices, an onslaught on coal and a year of geopolitical tumult, the World Bank has released its 2016 report on the outlook for the world’s commodity markets.
Carbon Brief looks at the five key takeaways for climate change and energy.
1. There’s All-Round Bad News for Coal
The report makes grim reading for coal industry executives. Coal prices are expected to continue their tumble downwards in 2016. Having fallen by more than 60 percent since 2011, prices are expected to drop a further 13 percent in the year ahead. This is attributed to a number of factors, which have, in turn, led to weak demand and oversupply.
The U.S. and Europe, in particular, are turning away from coal, as they pursue cleaner forms of energy.
China’s imports are falling, thanks to slowing industrial activity, other sources of energy coming online and government policies to limit coal use. The nation, with its smog-plagued cities, intends to reduce coal’s share of energy consumption to 62.6 percent this year, down from 64.4 percent in 2015 and has suspended the approval of new coal mines for three years in order to achieve this.
This decline will only be partly offset by demand in India and other emerging markets, the report says.
Despite this decline in demand, ample coal supplies are likely to still be available, as past investments lead to a ramp-up in new capacity. Spare capacity in Australia and Indonesia could also come online.
2. Geopolitics Will Continue to Affect Energy Markets
The energy market is not immune to the slings and arrows of wider geopolitical events. Oil and gas prices are highly susceptible to external conflicts and debates.
Iraq’s costly conflict with so-called Islamic State, alongside low oil prices, means that it is unlikely to continue its 2015 record crude oil production in the coming year. In 2015, the lifting of sanctions in Iran forced oil prices down further, in expectation of its oil further flooding the market—a larger-than-expected increase in exports could suppress prices in 2016, the report warns.
It also says that oil production could rise in Libya, following a UN-brokered agreement to form a new national government. After the deal was rejected by its parliament yesterday, this is an even more uncertain prospect.
The report points to the risk of supply disruptions in other key oil-producing countries, such as Nigeria and Venezuela, due to internal conflicts.
3. Warm Weather Depressed Oil Demand Growth, Which Will Continue to Shrink
2015 was the hottest year on record and consumption of oil and gas reflected this.
While overall growth in oil consumption reached a five-year high in 2015, it weakened in the fourth quarter of the year due to a mild winter in the northern hemisphere.
Mild weather was not the only pressure on oil consumption. Weakening economic growth, particularly in emerging markets, also slowed consumption growth. But it was shored up overall by the magnitude of the drop in oil prices, which encouraged consumption.
Oil consumption growth is expected to slow further in 2016, as oil prices begin to recover. Meanwhile, the UK’s Met Office has forecast that the coming year will once again break previous records.
It’s not just oil consumption that was impacted by the mild weather. Consumption of gas also weakened, helping to push U.S. gas prices down by 23 percent in 2015. Natural gas prices globally are projected to continue to fall in 2016, with U.S. prices specifically expected to drop by 4 percent.
4. U.S. Shale Gas Production Could Sharply Decline
Growth in global oil production slowed sharply in 2015. Most of this occurred in non-OPEC countries, bucking the trend of the last two-and-a-half years, during which U.S. production of shale oil boomed.
This is unlikely to be the case for much longer, according to the World Bank’s report. U.S. shale oil production could drop sharply in 2016. The amount of oil flowing from each drilled well drops sharply over time—by some 70 percent in the first year—and the U.S. is unlikely to offset these losses with new drilling.
U.S. crude oil production is also expected to accelerate its downward trend in 2016, as non-OPEC producers attempt to sustain oil prices of below $40 per barrel. Production from OPEC countries, on the other hand, is expected to rise.
5. Oil Prices Are Expected to Gradually Recover
The world watched on as oil prices continued their inexorable slide downwards in 2015, thanks to the lifting of sanctions on Iran, deteriorating growth in major energy-importing countries and OPEC’s refusal to cut oil production.
2016 promises some small relief, with the World Bank projecting that crude oil prices will average $37 per barrel. While this represents a decline by 27 percent on last year, it mean that the price would rise from recent lows of below $30 per barrel. This is because demand is expected to strengthen with a modest pickup in global economic growth, while high-cost oil producers are likely to cut production as they sustain increasing losses.
However, this recovery is likely to be less dramatic than historic rebounds after sharp drops in 2008, 1998 and 1986, says the report. This is because of large stocks, continuing ample supplies and low demand.

Guillain-Barre syndrome occurs when the body's own immune system attacks and injures the nerves outside of the spinal cord or brain – the peripheral nervous system. Niq Steele / Getty Images
By Sherry H-Y. Chou, Aarti Sarwal and Neha S. Dangayach
The patient in the case report (let's call him Tom) was 54 and in good health. For two days in May, he felt unwell and was too weak to get out of bed. When his family finally brought him to the hospital, doctors found that he had a fever and signs of a severe infection, or sepsis. He tested positive for SARS-CoV-2, the virus that causes COVID-19 infection. In addition to symptoms of COVID-19, he was also too weak to move his legs.
When a neurologist examined him, Tom was diagnosed with Guillain-Barre Syndrome, an autoimmune disease that causes abnormal sensation and weakness due to delays in sending signals through the nerves. Usually reversible, in severe cases it can cause prolonged paralysis involving breathing muscles, require ventilator support and sometimes leave permanent neurological deficits. Early recognition by expert neurologists is key to proper treatment.
We are neurologists specializing in intensive care and leading studies related to neurological complications from COVID-19. Given the occurrence of Guillain-Barre Syndrome in prior pandemics with other corona viruses like SARS and MERS, we are investigating a possible link between Guillain-Barre Syndrome and COVID-19 and tracking published reports to see if there is any link between Guillain-Barre Syndrome and COVID-19.
Some patients may not seek timely medical care for neurological symptoms like prolonged headache, vision loss and new muscle weakness due to fear of getting exposed to virus in the emergency setting. People need to know that medical facilities have taken full precautions to protect patients. Seeking timely medical evaluation for neurological symptoms can help treat many of these diseases.
What Is Guillain-Barre Syndrome?
Guillain-Barre syndrome occurs when the body's own immune system attacks and injures the nerves outside of the spinal cord or brain – the peripheral nervous system. Most commonly, the injury involves the protective sheath, or myelin, that wraps nerves and is essential to nerve function.
Without the myelin sheath, signals that go through a nerve are slowed or lost, which causes the nerve to malfunction.
To diagnose Guillain-Barre Syndrome, neurologists perform a detailed neurological exam. Due to the nerve injury, patients often may have loss of reflexes on examination. Doctors often need to perform a lumbar puncture, otherwise known as spinal tap, to sample spinal fluid and look for signs of inflammation and abnormal antibodies.
Studies have shown that giving patients an infusion of antibodies derived from donated blood or plasma exchange – a process that cleans patients' blood of harmful antibodies - can speed up recovery. A very small subset of patients may need these therapies long-term.
The majority of Guillain-Barre Syndrome patients improve within a few weeks and eventually can make a full recovery. However, some patients with Guillain-Barre Syndrome have lingering symptoms including weakness and abnormal sensations in arms and/or legs; rarely patients may be bedridden or disabled long-term.
Guillain-Barre Syndrome and Pandemics
As the COVID-19 pandemic sweeps across the globe, many neurologic specialists have been on the lookout for potentially serious nervous system complications such as Guillain-Barre Syndrome.
Though Guillain-Barre Syndrome is rare, it is well known to emerge following bacterial infections, such as Campylobacter jejuni, a common cause of food poisoning, and a multitude of viral infections including the flu virus, Zika virus and other coronaviruses.
Studies showed an increase in Guillain-Barre Syndrome cases following the 2009 H1N1 flu pandemic, suggesting a possible connection. The presumed cause for this link is that the body's own immune response to fight the infection turns on itself and attacks the peripheral nerves. This is called an "autoimmune" condition. When a pandemic affects as many people as our current COVID-19 crisis, even a rare complication can become a significant public health problem. That is especially true for one that causes neurological dysfunction where the recovery takes a long time and may be incomplete.
The first reports of Guillain-Barre Syndrome in COVID-19 pandemic originated from Italy, Spain and China, where the pandemic surged before the U.S. crisis.
Though there is clear clinical suspicion that COVID-19 can lead to Guillain-Barre Syndrome, many important questions remain. What are the chances that someone gets Guillain-Barre Syndrome during or following a COVID-19 infection? Does Guillain-Barre Syndrome happen more often in those who have been infected with COVID-19 compared to other types of infections, such as the flu?
The only way to get answers is through a prospective study where doctors perform systematic surveillance and collect data on a large group of patients. There are ongoing large research consortia hard at work to figure out answers to these questions.
Understanding the Association Between COVID-19 and Guillain-Barre Syndrome
While large research studies are underway, overall it appears that Guillain-Barre Syndrome is a rare but serious phenomenon possibly linked to COVID-19. Given that more than 10.7 million cases have been reported for COVID-19, there have been 10 reported cases of COVID-19 patients with Guillain-Barre Syndrome so far – only two reported cases in the U.S., five in Italy, two cases in Iran and one from Wuhan, China.
It is certainly possible that there are other cases that have not been reported. The Global Consortium Study of Neurological Dysfunctions in COVID-19 is actively underway to find out how often neurological problems like Guillain-Barre Syndrome is seen in hospitalized COVID-19 patients. Also, just because Guillain-Barre Syndrome occurs in a patient diagnosed with COVID-19, that does not imply that it was caused by the virus; this still may be a coincident occurrence. More research is needed to understand how the two events are related.
Due to the pandemic and infection-containment considerations, diagnostic tests, such as a nerve conduction study that used to be routine for patients with suspected Guillain-Barre Syndrome, are more difficult to do. In both U.S. cases, the initial diagnosis and treatment were all based on clinical examination by a neurological experts rather than any tests. Both patients survived but with significant residual weakness at the time these case reports came out, but that is not uncommon for Guillain-Barre Syndrome patients. The road to recovery may sometimes be long, but many patients can make a full recovery with time.
Though the reported cases of Guillain-Barre Syndrome so far all have severe symptoms, this is not uncommon in a pandemic situation where the less sick patients may stay home and not present for medical care for fear of being exposed to the virus. This, plus the limited COVID-19 testing capability across the U.S., may skew our current detection of Guillain-Barre Syndrome cases toward the sicker patients who have to go to a hospital. In general, the majority of Guillain-Barre Syndrome patients do recover, given enough time. We do not yet know whether this is true for COVID-19-related cases at this stage of the pandemic. We and colleagues around the world are working around the clock to find answers to these critical questions.

One of the initial reasons social distancing guidelines were put in place was to allow the healthcare system to adapt to a surge in patients since there was a critical shortage of beds, ventilators and personal protective equipment. In fact, masks that were designed for single-use were reused for an entire week in some hospitals.
<p>Now, five months into the pandemic, health care workers are raising the same concern. They are facing a shortage of masks, gowns, face shields and gloves, as <a href="https://www.washingtonpost.com/health/2020/07/08/ppe-shortage-masks-gloves-gowns/" target="_blank">The Washington Post</a> reported.</p><p>"We're five months into this and there are still shortages of gowns, hair covers, shoe covers, masks, N95 masks," said Deborah Burger, president of National Nurses United, who cited results from a survey of the union's members, as <a href="https://time.com/5863776/personal-protective-gear-shortage-us/" target="_blank">The Associated Press</a> reported. "They're being doled out, and we're still being told to reuse them."</p><p>In a survey of 23,000 registered nurses, National Nurses United found 85 percent were asked to reuse masks designed for single use, according to The Washington Post.</p>
<p>The new shortage is not just affecting urban hospitals like it did in March. The rising demand for protective gear is now plaguing a broad range of health care facilities across the country, from urgent cares to doctors' offices to nursing homes. Several major medical associations said this was a preventable problem that would have required swift and aggressive action from the federal government in the early days of the pandemic, according to <a href="https://www.nytimes.com/2020/07/08/health/coronavirus-masks-ppe-doc.html?action=click&module=Top%20Stories&pgtype=Homepage" target="_blank">The New York Times</a>. If the government had aggressively procured and distributed critical supplies, this shortage could have been avoided.</p><p>"A lot people thought once the alarm was sounded back in March surely the federal government would fix this, but that hasn't happened," said Burger to The Washington Post</p><p>She, like many health-care workers, blamed the <a href="http://www.ecowatch.com/trump-watch/" target="_self">Trump</a> administration for the lack of equipment. She pointed out that the administration has insisted the responsibility falls to state and local officials, with the federal government playing only a supporting role.</p><p>In a letter to Congress last week, the health department in DuPage County, Illinois, near Chicago, said all its hospitals are reusing protective gear "in ways that were not originally intended and are probably less safe than the optimal use of PPE," as The Associated Press reported.</p>
<p>Neurologists, cardiologists and cancer specialists around the country have been unable to reopen their offices in recent weeks, leaving many patients without care, according to a <a href="https://searchlf.ama-assn.org/undefined/documentDownload?uri=%2Funstructured%2Fbinary%2Fletter%2FLETTERS%2F2020-6-30-Letter-to-Gaynor-re-PPE.pdf" target="_blank">letter</a> from American Medical Association to the the Federal Emergency Management Agency, Vice President Mike Pence and members of Congress.</p><p>"We have kids living with grapefruit-sized abscesses for over three months who can't eat or drink and there's nothing we can do for them because we can't get P.P.E.," said Kay Kennel, the chief officer of Lubbock Kids Dental, to The New York Times. Her clinic serves low-income families in Texas and has a list of 50 children awaiting emergency surgery. "It's been just horrible, and given the growing number of infections here, I'm afraid things are going to get worse."</p>
<p>Rear Adm. John Polowczyk, who is in charge of coronavirus-related supplies for the White House, told Congress last week that more than one-fourth of the states have less than a 30-day supply.</p><p>"It would seem like in less than 30 days, we're going to have a real crisis," said Rep. Bill Foster, an Illinois Democrat, as The Associated Press reported.</p><p>That prompted the American Medical Association to write a <a href="https://searchlf.ama-assn.org/undefined/documentDownload?uri=%2Funstructured%2Fbinary%2Fletter%2FLETTERS%2F2020-6-30-Letter-to-Pence-re-PPE.pdf" target="_blank">letter</a> to the White House, asking it to invoke the Defense Protection Act to require American manufacturers to increase supplies of N95 masks and gowns, as The Washington Post reported.</p><p>Former Vice President Joe Biden said yesterday that he <a href="https://www.documentcloud.org/documents/6982369-Biden-Supply-Chain-Fact-Sheet-07-07-20.html?utm_source=newsletter&utm_medium=email&utm_campaign=newsletter_axiosvitals&stream=top" target="_blank" title="">would use that law</a> to boost domestic protection of medical gear if elected.</p>
<p>As the New York Times noted, the nation's supply of PPE is trapped in an unsustainable supply chain model. The U.S. remains dependent on overseas manufacturers and various middlemen who raised prices sevenfold amid soaring global demand. There are only a handful of U.S.-based companies still making PPEs and they say they are already at maximum capacity.</p><p>So far, more than 900 health care workers have died of COVID-19, according to a tally by National Nurses United. Burger said many of the deaths have been linked to inadequate protective gear.</p><p>"There are tools at President Trump's disposal and he has failed us," she said to The New York Times. "These deaths are entirely preventable."</p>

By Jake Johnson
Unity Task Forces formed by presumptive Democratic presidential nominee Joe Biden and Sen. Bernie Sanders unveiled sweeping party platform recommendations Wednesday that—while falling short of progressive ambitions in a number of areas, from climate to healthcare—were applauded as important steps toward a bold and just policy agenda that matches the severity of the moment.
"We've moved the needle a lot, especially on environmental justice and upping Biden's ambition," said Sunrise Movement co-founder and executive director Varshini Prakash, a member of the Biden-Sanders Climate Task Force. "But there's still more work to do to push Democrats to act at the scale of the climate crisis."
The climate panel—co-chaired by Rep. Alexandria Ocasio-Cortez (D-N.Y.) and former Secretary of State John Kerry—recommended that the Democratic Party commit to "eliminating carbon pollution from power plants by 2035," massively expanding investments in clean energy sources, and "achieving net-zero greenhouse gas emissions for all new buildings by 2030."
In a series of tweets Wednesday night, Ocasio-Cortez—the lead sponsor of the House Green New Deal resolution—noted that the Climate Task Force "shaved 15 years off Biden's previous target for 100% clean energy."
"Of course, like in any collaborative effort, there are areas of negotiation and compromise," said the New York Democrat. "But I do believe that the Climate Task Force effort meaningfully and substantively improved Biden's positions."
Today the 6 Biden-Sanders Unity Task Forces are unveiling final language. The Climate Task Force accomplished a gr… https://t.co/gz3broq2qe— Alexandria Ocasio-Cortez (@Alexandria Ocasio-Cortez)1594240617.0
The 110 pages of policy recommendations from the six eight-person Unity Task Forces on education, the economy, criminal justice, immigration, climate change, and healthcare are aimed at shaping negotiations over the 2020 Democratic platform at the party's convention next month.
Sanders said that while the "end result isn't what I or my supporters would've written alone, the task forces have created a good policy blueprint that will move this country in a much-needed progressive direction and substantially improve the lives of working families throughout our country."
"I look forward to working with Vice President Biden to help him win this campaign," the Vermont senator added, "and to move this country forward toward economic, racial, social, and environmental justice."
Biden, for his part, applauded the task forces "for helping build a bold, transformative platform for our party and for our country."
"I am deeply grateful to Bernie Sanders for working with us to unite our party and deliver real, lasting change for generations to come," said the former vice president.
On the life-or-death matter of reforming America's dysfunctional private health insurance system—a subject on which Sanders and Biden clashed repeatedly throughout the Democratic primary process—the Unity Task Force affirmed healthcare as "a right" but did not embrace Medicare for All, the signature policy plank of the Vermont senator's presidential bid.
Instead, the panel recommended building on the Affordable Care Act by establishing a public option, investing in community health centers, and lowering prescription drug costs by allowing the federal government to negotiate prices. The task force also endorsed making all Covid-19 testing, treatments, and potential vaccines free and expanding Medicaid for the duration of the pandemic.
"It has always been a crisis that tens of millions of Americans have no or inadequate health insurance—but in a pandemic, it's potentially catastrophic for public health," the task force wrote.
Dr. Abdul El-Sayed, a former Michigan gubernatorial candidate and Sanders-appointed member of the Healthcare Task Force, said that despite major disagreements, the panel "came to recommendations that will yield one of the most progressive Democratic campaign platforms in history—though we have further yet to go."
We rein in #pharma's greed by: 1) Allowing Medicare to FINALLY negotiate Rx drugs FOR ALL AMERICANS 2) Using Rx d… https://t.co/6k9iUCLMp7— Abdul El-Sayed (@Abdul El-Sayed)1594238411.0
Observers and advocacy groups also applauded the Unity Task Forces for recommending the creation of a postal banking system, endorsing a ban on for-profit charter schools, ending the use of private prisons, and imposing a 100-day moratorium on deportations "while conducting a full-scale study on current practices to develop recommendations for transforming enforcement policies and practices at ICE and CBP."
Marisa Franco, director of immigrant rights group Mijente, said in a statement that "going into these task force negotiations, we knew we were going to have to push Biden past his comfort zone, both to reconcile with past offenses and to carve a new path forward."
"That is exactly what we did, unapologetically," said Franco, a member of the Immigration Task Force. "For years, Mijente, along with the broader immigrant rights movement, has fought to reshape the narrative around immigration towards racial justice and to focus these very demands. We expect Biden and the Democratic Party to implement them in their entirety."
"There is no going back," Franco added. "Not an inch, not a step. We must only move forward from here."

Oregano oil is an extract that is not as strong as the essential oil, but appears to be useful both when consumed or applied to the skin. Peakpx / CC by 1.0
By Alexandra Rowles
Oregano is a fragrant herb that's best known as an ingredient in Italian food.
However, it can also be concentrated into an essential oil that's loaded with antioxidants and powerful compounds that have proven health benefits.
<p>Oregano oil is the extract and, although it's not as strong as the essential oil, it appears to be useful both when consumed or applied to the skin. Essential oils, on the other hand, are not meant to be consumed.</p><p>Interestingly, oregano oil is an effective natural antibiotic and antifungal agent, and it may help you lose weight and lower your cholesterol levels.</p>
<h2>What Is Oregano Oil?</h2><p>Botanically known as <em>Origanum vulgare</em>, oregano is a flowering plant from the same family as mint. It's often used as an herb to flavor food.</p><p>Although it's native to Europe, it now grows all over the world.</p><p>Oregano has been popular ever since the ancient Greek and Roman civilizations used it for medicinal purposes. In fact, the name oregano comes from the Greek words "oros," meaning mountain, and "ganos," meaning joy or delight.</p><p>The herb has also been used for centuries as a culinary spice.</p><p>Oregano essential oil is made by air-drying the leaves and shoots of the plant. Once they're dried, the oil is extracted and concentrated by steam distillation.</p><p>Oregano essential oil can be mixed with a carrier oil and applied topically. However, it should not be consumed orally.</p><p>Oregano oil extract, on the other hand, can be produced via several extraction methods using compounds like carbon dioxide or alcohol. It's widely available as a supplement and can often be found in pill or capsule form.</p><p>Oregano contains compounds called phenols, terpenes, and terpenoids. They have powerful antioxidant properties and are responsible for its fragrance:</p><ul><li><strong>Carvacrol.</strong> The most abundant phenol in oregano, it has been shown to stop the growth of several different types of bacteria.</li><li><strong>Thymol.</strong> This natural antifungal can also support the immune system and protect against toxins.</li><li><strong>Rosmarinic acid.</strong> This powerful antioxidant helps protect against damage caused by free radicals.</li></ul><p>These compounds are thought to underlie oregano's many health benefits.</p><p>Here are 9 potential benefits and uses of oregano oil.</p><h2>1. Natural Antibiotic<a target="_blank"><br></a></h2><p><a href="https://www.healthline.com/nutrition/6-oregano-benefits" target="_blank">Oregano</a> and the carvacrol it contains may help fight bacteria.</p><p>The <em>Staphylococcus aureus</em> bacterium is one of the most common causes of infection, resulting in ailments like food poisoning and skin infections.</p><p>One particular study looked at whether oregano essential oil improved the survival of 14 mice infected with <em>Staphylococcus aureus</em>.</p><p>It found that 43% of the mice given oregano essential oil lived past 30 days, a survival rate nearly as high as the 50% survival rate for mice that received regular antibiotics.</p><p>Research has also shown that oregano essential oil may be effective against some potentially antibiotic-resistant bacteria.</p><p>This includes <em>Pseudomonas aeruginosa</em> and <em>E. coli</em>, both of which are common causes of <a href="https://www.healthline.com/nutrition/uti-home-remedies/" target="_blank">urinary</a> and respiratory tract infections.</p><p>Although more human studies on the effects of oregano oil extract are needed, it contains many of the same compounds as oregano essential oil and may offer similar health benefits when used as a supplement.</p><p><strong>SUMMARY</strong></p><p><strong></strong>One mouse study found oregano essential oil to be almost as effective as antibiotics against common bacteria, though much more research is needed.</p>
<h2>2. May Help Lower Cholesterol</h2><p>Studies have shown that oregano oil may help <a href="https://www.healthline.com/nutrition/how-to-lower-cholesterol" target="_blank">lower cholesterol</a>.</p><p>In one study, 48 people with mildly high cholesterol were given diet and lifestyle advice to help lower their cholesterol. Thirty-two participants were also given 0.85 ounces (25 mL) of oregano oil extract after each meal.</p><p>After 3 months, those given the oregano oil had lower LDL (bad) cholesterol and higher HDL (good) cholesterol, compared with those who were just given diet and lifestyle advice.</p><p>Carvacrol, the main compound in oregano oil, has also been shown to help lower cholesterol in mice that were fed a high fat diet over 10 weeks.</p><p>The mice given carvacrol alongside the high fat diet had significantly lower cholesterol at the end of the 10 weeks, compared with those that were just given a high fat diet.</p><p>The cholesterol-lowering effect of oregano oil is thought to be the result of the phenols carvacrol and thymol.</p><p><strong>SUMMARY</strong></p><p><strong></strong>Studies have shown that oregano may help lower cholesterol in people and mice with high cholesterol. This is thought to be the result of the compounds carvacrol and thymol.</p><h2>3. Powerful Antioxidant</h2><p><a href="https://www.healthline.com/nutrition/antioxidants-explained" target="_blank">Antioxidants</a> help protect the body from damage caused by free radicals.</p><p>It's thought that free radical damage plays a role in aging and the development of some diseases, such as cancer and heart disease.</p><p>Free radicals are everywhere and a natural product of metabolism.</p><p>However, they can build up in the body through exposure to environmental factors, such as cigarette smoke and air pollutants.</p><p>One older test-tube study compared the antioxidant content of 39 commonly used herbs and found that oregano had the highest concentration of antioxidants.</p><p>It found that oregano contained 3–30 times the levels of antioxidants in the other herbs studied, which included thyme, marjoram, and <a href="https://www.healthline.com/nutrition/st-johns-wort/" target="_blank">St. John's wort</a>.</p><p>Gram per gram, oregano also has 42 times the antioxidant level of apples and 4 times that of blueberries. This is thought to be mostly due to its rosmarinic acid content.</p><p>Because oregano oil extract is very concentrated, you need much less oregano oil to reap the same antioxidant benefits as you would from fresh oregano.</p><p><strong>SUMMARY</strong></p><p><strong></strong>Fresh oregano has a very high antioxidant content. In fact, it's much higher than that of most fruits and vegetables, gram per gram. The antioxidant content is concentrated in oregano oil.</p>
<h2>4. Could Help Treat Yeast Infections</h2><p>Yeast is a type of fungus. It can be harmless, but overgrowth can result in gut problems and infections, such as thrush.</p><p>The most well-known yeast is <em><a href="https://www.healthline.com/nutrition/candida-symptoms-treatment" target="_blank">Candida</a></em>, which is the most common cause of yeast infections worldwide.</p><p>In test-tube studies, oregano essential oil has been found to be effective against five different types of <em>Candida</em>, such as those that cause infections in the mouth and vagina. In fact, it was more effective than any other essential oil tested.</p><p>Test-tube studies have also found that carvacrol, one of the main compounds of oregano oil, is very effective against oral <em>Candida</em>.</p><p>High levels of the yeast <em>Candida</em> have also been associated with some gut conditions, such as Crohn's disease and ulcerative colitis.</p><p>A test-tube study on the effectiveness of oregano essential oil on 16 different strains of <em>Candida</em> concluded that oregano oil may be a good <a href="https://www.healthline.com/nutrition/5-diet-tips-against-candida/" target="_blank">alternative treatment</a> for <em>Candida</em> yeast infections. However, more research is needed.</p><p><strong>SUMMARY</strong></p><p><strong></strong>Test-tube studies have shown that oregano essential oil is effective against <em>Candida</em>, the most common form of yeast.</p><h2>5. May Improve Gut Health</h2><p>Oregano may <a href="https://www.healthline.com/nutrition/improve-gut-bacteria/" target="_blank">benefit gut health</a> in a number of ways.</p><p>Gut symptoms like diarrhea, pain, and bloating are common and can be caused by gut parasites.</p><p>One older study gave 600 mg of oregano oil to 14 people who had gut symptoms as a result of a parasite. After daily treatment for 6 weeks, all participants experienced a reduction in parasites, and 77% were cured.</p><p>Participants also experienced a reduction in gut symptoms and tiredness associated with the symptoms.</p><p>Oregano may also help protect against another common gut complaint known as "<a href="https://www.healthline.com/nutrition/is-leaky-gut-real/" target="_blank">leaky gut</a>." This happens when the gut wall becomes damaged, allowing bacteria and toxins to pass into the bloodstream.</p><p>In a study on pigs, oregano essential oil protected the gut wall from damage and prevented it from becoming "leaky." It also reduced the number of <em>E. coli</em> bacteria in the gut. </p><p><strong>SUMMARY</strong></p><p><strong></strong>Oregano oil may benefit gut health by killing gut parasites and protecting against leaky gut syndrome.</p>
<h2>6. May Have Anti-Inflammatory Properties</h2><p>Inflammation in the body is linked to a number of adverse health effects.</p><p>Research has shown that oregano oil may <a href="https://www.healthline.com/nutrition/anti-inflammatory-diet-101/" target="_blank">reduce inflammation</a>.</p><p>One mouse study found that oregano essential oil, along with thyme essential oil, reduced inflammatory markers in those that had artificially induced colitis.</p><p>Carvacrol, one of the key components in oregano oil, has also been shown to reduce inflammation.</p><p>One study directly applied different concentrations of carvacrol to the swollen paws or ears of mice. Carvacrol reduced paw and ear swelling by 35–61% and 33–43%, respectively.</p><p><strong>SUMMARY</strong></p><p><strong></strong>Oregano oil and its components may help reduce inflammation in mice, though human studies are needed.</p><h2>7. Could Help Relieve Pain</h2><p>Oregano oil has been investigated for its painkilling properties.</p><p>One older study in mice tested standard painkillers and <a href="https://www.healthline.com/nutrition/what-are-essential-oils/" target="_blank">essential oils</a>, including oregano essential oil, for their ability to relieve pain.</p><p>It found that oregano essential oil significantly reduced pain in mice, exerting effects similar to those of the commonly used painkillers fenoprofen and morphine.</p><p>The research proposed these results were likely due to the carvacrol content of oregano.</p><p>A similar study found that oregano extract reduced pain in rats, and that the response was dose-dependent, meaning the more oregano extract the rats consumed, the less pain they appeared to feel.</p><p><strong>SUMMARY</strong></p><p><strong></strong>Oregano oil may significantly reduce pain in mice and rats, exerting pain-relieving effects similar to those of some commonly used medications.</p>
<h2>8. May Have Cancer-Fighting Properties</h2><p>A few studies have indicated that carvacrol, one of the compounds of oregano oil, may have cancer-fighting properties.</p><p>In test-tube studies on cancer cells, carvacrol has demonstrated promising results against lung, liver, and breast cancer cells.</p><p>It has been found to inhibit cell growth and cause cancer cell death.</p><p>Although this is promising research, no studies have been carried out on people, so more research is needed.</p><p><strong>SUMMARY</strong></p><p><strong></strong>Preliminary studies have shown that carvacrol — the most abundant compound in oregano oil — inhibits cancer cell growth and causes cell death in lung, liver, and breast cancer cells.</p><h2>9. May Help You Lose Weight</h2><p>Thanks to oregano's carvacrol content, oregano oil may aid weight loss.</p><p>In one study, mice were fed either a normal diet, high fat diet, or high fat diet with carvacrol. Those given carvacrol alongside their high fat diet gained significantly less weight and body fat than those just given a high fat diet.</p><p>Furthermore, carvacrol appeared to reverse the chain of events that can lead to the formation of fat cells.</p><p>More research is needed to demonstrate that oregano oil has a role in weight loss, but it may be worth trying as part of a <a href="https://www.healthline.com/nutrition/healthy-eating-for-beginners/" target="_blank">healthy diet</a> and lifestyle.</p><p><strong>SUMMARY</strong></p><p><strong></strong>Oregano oil may be beneficial for weight loss through the action of carvacrol, though human studies are needed.</p>
<h2>How to Use Oregano Oil</h2><p>Oregano oil extract is widely available in capsule and tablet form. It can be bought from most health food shops or online.</p><p>Because the strength of oregano supplements can vary, it's important to read the directions on the individual packet for instructions on how to use the product.</p><p>Oregano essential oil is also available and can be diluted with a <a href="https://www.healthline.com/health/carrier-oil" target="_blank">carrier oil</a> and applied topically. Note that no essential oil should be ingested.</p><p>There's no standard effective dose of oregano essential oil. However, it's often mixed with around 1 teaspoon (5 mL) of olive oil per drop of oregano essential oil and applied directly to the skin.</p><p>Like other essential oils, keep in mind that oregano essential oil should not be consumed orally.</p><p>If you're interested in taking oregano oil extract but currently taking prescription medications, make sure to consult your healthcare provider before adding it to your regimen.</p><p>In addition, oregano oil extract is not generally recommended for women who are pregnant or breastfeeding.</p><p><strong>SUMMARY</strong></p><p><strong></strong>Oregano oil extract can be purchased in pill or capsule form and taken orally. Oregano essential oil is also available and can be diluted with a carrier oil and applied to the skin.</p><h2>The Bottom Line</h2><p>Oregano oil extract and oregano essential oil are both relatively cheap and readily available.</p><p>Oregano is higher in antioxidants than most fruits and vegetables, and it's packed full of powerful compounds called phenols.</p><p>Oregano also contains compounds that may be effective against bacterial and fungal infections, inflammation, and pain, among other conditions.</p><p>Overall, it appears to have several health benefits and may be useful as a natural treatment for some common health complaints.</p>

Brazilian President Jair Bolsonaro meets Ronaldo Caiado, governor of the state of Goiás on June 5, 2020. Palácio do Planalto / CC BY 2.0
Far-right Brazilian President Jair Bolsonaro, who has presided over the world's second worst coronavirus outbreak after the U.S., said Tuesday that he had tested positive for the virus.
<p>The news comes after Bolsonaro has repeatedly dismissed the risk posed by the virus both to himself and others and argued against social distancing measures as a threat to the economy.</p><p>"In my particular case, because of my history as an athlete, in case I were contaminated by the virus I wouldn't need to worry. I wouldn't feel anything or it would be, at most, similar to a little flu, or a little cold," he said during a national television address March 24, as <a href="https://abcnews.go.com/Health/wireStory/ap-explains-bolsonaro-downplayed-virus-fears-months-71663418" target="_blank">The Associated Press reported</a>.</p>
<p>His approach has earned him protests at home and worldwide criticism for allowing the virus to spread in his country, <a href="https://www.nytimes.com/2020/07/07/world/americas/brazil-bolsonaro-coronavirus.html?auth=login-googl" target="_blank">The New York Times reported</a>. He fired one health minister in April over disagreements about how to respond to the pandemic and forced a second to quit less than a month later. The current health minister is an active-duty general with no medical experience. Brazil has now reported more than 1.6 million confirmed cases and more than 65,000 deaths, falling second only to the U.S. in both categories.</p><p>Bolsonaro took a test for the virus Monday after falling ill with fatigue, muscle pain and a fever. His illness occurred two days after he attended a Fourth of July lunch at the home of Brazil's U.S. Ambassador Todd Chapman, where Bolsonaro and other attendees were pictured sitting side by side without masks. The ambassador and his wife have since tested negative for the virus but are remaining in quarantine.</p>

<p>So far, Bolsonaro's diagnosis has not changed his tone. As he announced his test results, he continued to focus on the importance of reopening Brazil's economy.</p><p>"You can't just talk about the consequences of the virus that you have to worry about. Life goes on. Brazil needs to produce. You need to get the economy in gear,″ he said, according to The Associated Press.</p><p>He was also widely criticized on social media for taking off his mask while speaking to reporters about his diagnosis, <a href="https://indianexpress.com/article/trending/trending-globally/brazilian-president-takes-off-mask-after-announcing-he-tested-positive-for-covid-19-6495517/" target="_blank">The Indian Express reported</a>.</p>

Like Trump, Bolsonaro has touted the benefits of hydroxychloroquine for treating the coronavirus, an anti-malaria drug that the Food and Drug Administration <a href="https://www.ecowatch.com/coronavirus-malaria-drugs-2646183392.html" target="_self">has warned</a> against taking for COVID-19.</p><p>But Bolsonaro said his medical team was treating him with the drug on Tuesday and that he was feeling "very well," according to The New York Times.</p><p>Politicians and <a href="https://www.ecowatch.com/tag/public-health" target="_self">public health</a> experts said that Bolsonaro's diagnosis was unlikely to change Brazil's approach to the virus unless he grew seriously ill. The country is currently in the process of reopening.</p>
<p>"My concern is that he will use this to say, 'See, I'm fine, if you catch this you will survive,'" Rio de Janeiro community activist Day Medeiros told The New York Times. "Everything that happens to him has real repercussions in how people behave here. This is really serious."</p><p>But one analyst thought the diagnosis would ultimately harm Bolsoarno's political career.</p><p>"Despite publicly shrugging off his positive test for Covid-19, it marks the beginning of the end of his administration," Robert Muggah, director of Rio-based think tank the Igarape Institute, told <a href="https://www.cnbc.com/2020/07/08/coronavirus-bolsonaros-diagnosis-marks-beginning-of-the-end-for-his-administration.html" target="_blank">CNBC in an email</a>. "It is yet another visible expression of his recklessness and ineptitude."</p>

Although natural gas produces fewer greenhouse gas emissions and other pollutants than coal or oil, it is a major contributor to climate change, an urgent global problem. Skitterphoto / PIxabay
By Emily Grubert
Natural gas is a versatile fossil fuel that accounts for about a third of U.S. energy use. Although it produces fewer greenhouse gas emissions and other pollutants than coal or oil, natural gas is a major contributor to climate change, an urgent global problem. Reducing emissions from the natural gas system is especially challenging because natural gas is used roughly equally for electricity, heating, and industrial applications.
<p>There's an emerging argument that maybe there could be a direct substitute for fossil natural gas in the form of renewable natural gas (RNG) – a renewable fuel designed to be nearly indistinguishable from fossil natural gas. RNG could be made from biomass or from captured carbon dioxide and electricity.</p><p>Based on what's known about these systems, however, I believe climate benefits might not be as large as advocates claim. This matters because RNG isn't widely used yet, and decisions about whether to invest in it are being made now, in places like <a href="https://www.cleanenergyfuels.com/blog/influx-of-california-rng-fuels-local-economy-protects-climate" target="_blank">California</a>, <a href="https://www.oregon.gov/energy/Get-Involved/Pages/RNG-Advisory-Committee.aspx" target="_blank">Oregon</a>, <a href="http://biomassmagazine.com/articles/15172/inslee-signs-bill-to-promote-rng-in-state-of-washington" target="_blank">Washington</a>, <a href="https://energynews.us/2019/12/03/midwest/michigan-utilities-see-role-for-renewable-natural-gas-but-cost-barrier-remains/" target="_blank">Michigan</a>, <a href="https://investor.southerncompany.com/information-for-investors/latest-news/latest-news-releases/press-release-details/2020/Southern-Company-Gas-grows-leadership-team-to-focus-on-climate-action-innovation-and-renewable-natural-gas-strategy/default.aspx" target="_blank">Georgia</a> and <a href="https://www.epa.gov/natural-gas-star-program/rng-interconnect-guideline-new-york" target="_blank">New York</a>.</p><p>As someone who studies <a href="https://scholar.google.com/citations?user=3RI02dcAAAAJ&hl=en" target="_blank">sustainability</a>, I research how decisions made now might influence the environment and society in the future. I'm particularly interested in how energy systems contribute to climate change.</p><p>Right now, energy is responsible for most of the pollution worldwide that <a href="https://www.ipcc.ch/report/ar5/syr/" target="_blank">causes climate change</a>. Since energy infrastructure, like power plants and pipelines, <a href="http://emilygrubert.org/wp-content/uploads/2019/02/eia_860_2017_map.html" target="_blank">lasts a long time</a>, it's important to consider the climate change emissions that society <a href="https://doi.org/10.1038/s41586-019-1364-3" target="_blank">is committing to</a> with new investments in these systems. At the moment, renewable natural gas is more a proposal than reality, which makes this a great time to ask: What would investing in RNG mean for climate change?</p>
<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="6bd9fda1316965a9ba24dd60fd9cc34d"><iframe lazy-loadable="true" src="https://www.youtube.com/embed/3KaMnkmf0tc?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span>
What RNG Is and Why it Matters
<p>Most equipment that uses energy can only use a single kind of fuel, but the fuel might come from different resources. For example, you can't charge your computer with gasoline, but it can run on electricity generated from coal, natural gas or solar power.</p><p>Natural gas is almost pure methane, <a href="https://www.eia.gov/energyexplained/natural-gas/" target="_blank">currently sourced</a> from raw, fossil natural gas produced from <a href="https://www.eia.gov/energyexplained/natural-gas/where-our-natural-gas-comes-from.php" target="_blank">deposits deep underground</a>. But methane could come from renewable resources, too.</p><p><span></span>Two main methane sources could be used to make RNG. First is <a href="https://www.epa.gov/ghgemissions/inventory-us-greenhouse-gas-emissions-and-sinks" target="_blank">biogenic methane</a>, produced by bacteria that digest organic materials in manure, landfills and wastewater. Wastewater treatment plants, landfills and dairy farms have captured and used biogenic methane as an energy resource for <a href="http://emilygrubert.org/wp-content/uploads/2019/02/eia_860_2017_map.html" target="_blank">decades</a>, in a form usually called <a href="https://www.eia.gov/energyexplained/biomass/landfill-gas-and-biogas.php" target="_blank">biogas</a>.</p><p>Some biogenic methane is generated naturally when organic materials break down without oxygen. Burning it for energy can be beneficial for the climate if doing so prevents methane from escaping to the atmosphere.</p><p>In theory, there's enough of this climate-friendly methane available to replace <a href="https://iopscience.iop.org/article/10.1088/1748-9326/ab9335/meta" target="_blank">about 1% of the energy</a> that the current natural gas system provides. The largest share is found at landfills.</p><p>The other source for RNG doesn't exist in practice yet, but could theoretically be a much larger resource than biogenic methane. Often called <a href="https://www.powermag.com/why-power-to-gas-may-flourish-in-a-renewables-heavy-world/" target="_blank">power-to-gas</a>, this methane would be intentionally manufactured from carbon dioxide and hydrogen using electricity. If all the inputs are climate-neutral – meaning, for example, that the electricity used to create the RNG is generated from resources without greenhouse gas emissions – then the combusted RNG would also be climate-neutral.</p><p>So far, RNG of either type isn't widely available. Much of the current conversation focuses on whether and how to make it available. For example, <a href="https://www.sempra.com/socalgas-takes-next-step-toward-offering-renewable-natural-gas" target="_blank">SoCalGas in California</a>, <a href="https://energynews.us/2019/01/30/midwest/minnesota-utility-wants-to-offer-customers-renewable-natural-gas-option/" target="_blank">CenterPoint Energy in Minnesota and Vermont Gas Systems in Vermont</a> either offer or have proposed offering RNG to consumers, in the same way that many utilities allow customers to opt in to renewable electricity.</p>
Renewable Isn’t Always Sustainable
<p>If RNG could be a renewable replacement for fossil natural gas, why not move ahead? Consumers have shown that they are <a href="https://www.nrel.gov/analysis/green-power.html" target="_blank">willing to buy renewable electricity</a>, so we might expect similar enthusiasm for RNG.</p><p>The key issue is that methane isn't just a fuel – it's also a <a href="https://www.eia.gov/environment/emissions/ghg_report/ghg_overview.php" target="_blank">potent greenhouse gas</a> that contributes to climate change. Any methane that is manufactured intentionally, whether from biogenic or other sources, will contribute to climate change if it enters the atmosphere.</p><p>And <a href="http://doi.org/10.1126/science.aar7204" target="_blank">releases</a> <a href="https://doi.org/10.1016/j.wasman.2019.07.029" target="_blank">will happen</a>, from newly built production systems and <a href="https://theconversation.com/why-methane-emissions-matter-to-climate-change-5-questions-answered-122684" target="_blank">existing, leaky transportation and user infrastructure</a>. For example, the moment you smell gas before the pilot light on a stove lights the ring? That's methane leakage, and it contributes to climate change.</p><p>To be clear, RNG is almost certainly better for the climate than fossil natural gas because byproducts of burning RNG won't contribute to climate change. But doing somewhat better than existing systems is no longer enough to respond to the <a href="https://doi.org/10.1038/nclimate2923" target="_blank">urgency</a> of climate change. The world's <a href="https://www.ipcc.ch/sr15/chapter/spm/" target="_blank">primary international body on climate change</a> suggests we need to decarbonize by 2030 to mitigate the worst effects of climate change.</p>Scant Climate Benefits
<p><a href="https://iopscience.iop.org/article/10.1088/1748-9326/ab9335/meta" target="_blank">My recent research</a> suggests that for a system large enough to displace a lot of fossil natural gas, RNG is probably not as good for the climate as <a href="https://investor.southerncompany.com/information-for-investors/latest-news/latest-news-releases/press-release-details/2020/Southern-Company-Gas-grows-leadership-team-to-focus-on-climate-action-innovation-and-renewable-natural-gas-strategy/default.aspx" target="_blank">is publicly claimed</a>. Although RNG has lower climate impact than its fossil counterpart, likely high demand and methane leakage mean that it probably will contribute to climate change. In contrast, renewable sources such as wind and solar energy do not <a href="https://www.eia.gov/environment/emissions/carbon/" target="_blank">emit climate pollution directly</a>.</p><p>What's more, creating a large RNG system would require building mostly new production infrastructure, since RNG comes from different sources than fossil natural gas. Such investments are both long-term commitments and opportunity costs. They would devote money, political will and infrastructure investments to RNG instead of alternatives that could achieve a zero greenhouse gas emission goal.</p><p>When climate change first <a href="https://www.nytimes.com/1988/06/24/us/global-warming-has-begun-expert-tells-senate.html" target="_blank">broke into the political conversation</a> in the late 1980s, investing in long-lived systems with low but non-zero greenhouse gas emissions was still compatible with aggressive climate goals. Now, zero greenhouse gas emissions is the target, and my research suggests that large deployments of RNG likely won't meet that goal.</p>From Your Site Articles
