Following the nomination of Gina McCarthy to head the U.S. Environmental Protection Agency (EPA), conservative media are once again claiming that the Obama administration's U.S. EPA has waged a "war on coal." But that narrative ignores how natural gas has outcompeted coal, and why the long-overdue Clean Air Act regulations on coal are necessary in the first place. Here's what the public should know, as told in charts and graphics:
Low natural gas prices are behind the drop in coal power.
Clean Air Act regulations are long-overdue.
George H.W. Bush's EPA administrator acknowledged that the Obama administration inherited several court-mandated rules from previous administrations, calling them "grenades" that required action. For instance, this timeline put together by energy giant Dynegy shows that the Mercury and Air Toxics rule issued under the Obama administration underwent a "thorough and lengthy development process." The 1990 Clean Air Act amendments required that the EPA study mercury and other emissions. In 2005, the EPA issued its final rule for controlling mercury that the Bush administration's own lawyers reportedly said would "almost certainly be reversed" by the courts. After the courts indeed reversed it, the burden of complying with the requirement to regulate mercury fell to the Obama administration:

Coal has huge health impacts even after decades of regulation in the U.S.
In countries like China and India where coal is not as strictly regulated, coal pollution is extremely deadly. Meanwhile, in the U.S., harmful emissions have been significantly reduced, a fact that conservative media and the coal industry have used to tout coal's alleged cleanliness. But they often fail to mention that the industry only reduced its emissions after being required to by clean air standards, and that coal still has huge health impacts. The following chart details some of the known and quantifiable health impacts of pollution from coal plants:
These health impacts have huge economic costs.
After studying 406 coal-fired power plants in the U.S., the National Academy of Sciences concluded in 2009 that they were causing approximately $62 billion in societal damages, not including their contribution to climate change. The vast majority of damages were related to adverse health effects, but the report found that coal plants also do harm to agriculture and outdoor recreation.

But coal plants are not paying for these costs.
Two economists, including one who spoke at the right-wing Heartland Institute's conference on climate change, published a study in the prestigious American Economic Review finding that the gross external damages (GED), or the amount of external costs that an industry imposes on society through pollution and other harm, was higher for coal-fired power plants than for any other industry, and that these plants "are responsible for more than one-fourth of GED from the entire US economy." As the GED costs of the coal power industry were greater than the value it added to the economy, the study concluded that coal may actually be "underregulated"—and therefore only superficially "cheap."

And that's not even including the damage coal plants do to the climate.
That same study found that coal plants do an additional $15 billion in damage to the economy through carbon emissions that contribute to climate change, using a conservative calculation of the cost of carbon. Indeed the carbon emissions of lignite coal and black coal per kilowatt-hour produced are far more than the emissions of any other power source:
And worldwide, the huge amounts of coal reserves are poised to bust the carbon budget more than any other fossil fuel. There are already major projects underway to exploit these resources, rather than leaving them in the ground.
The Obama administration has made significant investments to try to make coal "cleaner."
The following chart shows that the stimulus devoted far more funding for demonstration projects to Carbon Capture and Storage (CCS), projects that would try to advance thus-far elusive "clean coal" by capturing its huge carbon emissions and burying them underground, than similar projects for solar energy. The Energy Innovation Tracker report that this chart came from called demonstration projects "crucial" because they are "often expensive and underfunded by the private sector," a phenomenon known as the "commercialization valley of death." In total the stimulus devoted $3.4 billion to CCS. That is less than it appropriated for renewable generation overall, but it is nevertheless a significant investment in technology that could enable coal power to be compatible with a low-carbon future—a far cry from waging a "war" on the energy source.

Since even moderate-intensity workouts offer a slew of benefits, walking is a good choice for people looking to stay healthy.
How to Rock Your Walk<p>Walking isn't just fun and healthy. It's accessible.</p><p>"Walking is cheap," says Dr. John Paul H. Rue, a sports medicine doctor at <a href="https://mdmercy.com/" target="_blank">Mercy Medical Center in Baltimore</a>. "You can do it anywhere at any time; [it] requires little to no special equipment and has many of the same cardio benefits as running or other more intense workouts."</p><p>Want to up your walking game? Try the tips below.</p>
Use Hand Weights<p>Cardio and strength training can go hand-in-hand when you add weights to your walk.</p><p>A <a href="https://journals.lww.com/acsm-msse/Fulltext/2019/03000/Associations_of_Resistance_Exercise_with.14.aspx" target="_blank">2019 study</a> found that weight training is good for your heart, and <a href="https://www.mayoclinicproceedings.org/article/S0025-6196(17)30167-2/abstract" target="_blank">research</a> shows it reduces the risk of developing a <a href="https://www.healthline.com/health/nutrition-metabolism-disorders" target="_blank">metabolic disorder</a> by 17 percent. People with metabolic disorders have a higher chance of being diagnosed with high cholesterol, high blood pressure, and diabetes.</p><p>Rue suggests not carrying weights for your entire walk.</p><p>"Hand weights can give you an added level of energy burning, but you have to be careful with these because carrying [them] over a long period of time or while walking could actually lead to some overuse injuries," he says.</p>
Make It a Circuit<p>As another option, consider doing a circuit. First, put a pair of dumbbells on your lawn or somewhere in your home. Walk around the block once, then stop and do some bicep curls and tricep lifts before walking around the block again.</p><p>Rue recommends <a href="https://www.healthline.com/health/exercise-fitness/running-with-weights" target="_blank">avoiding ankle weights</a> during cardio workouts, as they force you to use your quadriceps rather than hamstrings. They can also cause muscle imbalance, according to the <a href="https://www.health.harvard.edu/staying-healthy/wearable-weights-how-they-can-help-or-hurt" target="_blank">Harvard Health Letter</a>.</p>
Find a Fitness Trail<p>Strength training isn't limited to weights. You can get stronger by <a href="https://www.healthline.com/health/bodyweight-workout" target="_blank">simply using your body</a>.</p><p>Often found at parks, fitness trails are obstacle courses with equipment for pullups, pushups, rowing, and stretches to build upper and lower body strength.</p><p>Try searching "fitness trails near me" online, checking out your local parks and recreation website, or calling the municipal office to <a href="https://calisthenics-parks.com/" target="_blank">find one</a>.</p>
Recruit a Friend<p>People who workout together stay healthy together.</p><p><a href="https://bmcgeriatr.biomedcentral.com/articles/10.1186/s12877-017-0584-3" target="_blank">One study</a> showed that older adults who exercised with a group improved or maintained their functional health and enjoyed their lives more.</p><p>Enlist the help of a walking buddy with a regimen you aspire to have. If you don't know anyone in your area, apps like <a href="https://www.strava.com/" target="_blank">Strava</a> have social networking features so you can get support from fellow exercisers.</p>
Try Meditation<p>According to the <a href="https://www.nccih.nih.gov/research/statistics/nhis/2017" target="_blank">2017 National Health Interview Survey</a>, published by the National Institutes of Health, meditation is on the rise, and for good reason.</p><p>Researchers <a href="https://pubmed.ncbi.nlm.nih.gov/29616846/" target="_blank">found</a> that mind-body relaxation practices can regulate inflammation, <a href="https://www.healthline.com/health/biological-rhythms" target="_blank">circadian rhythms</a>, and <a href="https://www.healthline.com/health/glucose" target="_blank">glucose</a> metabolism, as well as lower <a href="https://www.healthline.com/health/high-blood-pressure-hypertension" target="_blank">blood pressure</a>.</p><p>"Any form of exercise can be turned into a meditation of some type, either by the surroundings you are walking in, like a park or trail, or by blocking out the outside world with music on your headphones," Rue says.</p><p>You can also play a podcast or download an app like <a href="https://www.headspace.com/headspace-meditation-app" target="_blank">Headspace</a> that has a library of guided meditations to practice while you walk.</p>
Do Fartlek Walks<p>Typically used in running, fartlek intervals alternate periods of increased and decreased speed. These are <a href="https://www.healthline.com/nutrition/benefits-of-hiit" target="_blank">high-intensity interval training (HIIT)</a> workouts, which allow exercisers to accomplish more in less time.</p><p><a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0154075" target="_blank">One study</a> showed that 10-minute interval training improved <a href="https://www.healthline.com/health/metabolic-syndrome" target="_blank">cardiometabolic</a> health, or lowered the risk of heart disease, stroke, and diabetes, just as well as working out at a continuous pace for 50 minutes.</p><p><a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0111489" target="_blank">Research</a> also shows that HIIT workouts increase muscle <a href="https://www.healthline.com/health/fast-twitch-muscles" target="_blank">oxidative</a> capacity, or the ability to use oxygen. To do a fartlek walk, try walking at an increased pace for 3 minutes, slow down for 2 minutes, and repeat.</p>
Gradually Increase Pace<p>A faster walking pace is associated with a lower risk of <a href="https://www.healthline.com/health/copd" target="_blank">chronic obstructive pulmonary disease (COPD)</a> and respiratory diseases, according to a <a href="https://pubmed.ncbi.nlm.nih.gov/30303933/" target="_blank">2019 study</a>.</p><p>Still, it's best not to go from a stroll to an Olympic-worthy power walk in a day. Instead, increase your pace gradually to prevent injury.</p><p>"Start by walking at a brisk pace for about 10 minutes per day, 3 to 5 days per week," Rue says. "Once you've done this for a few weeks, increase your time by 5 to 10 minutes per day until you get to 30 minutes."</p>
Add Stairs<p>You've likely heard that taking the stairs instead of an elevator is a way to add more movement into your daily routine. It's also a way to step up your walking. Stair climbing has been shown to <a href="https://www.sciencedirect.com/science/article/pii/S2211335519301123?via%3Dihub" target="_blank">decrease the risk of mortality</a> and can easily add a bit more challenge to your walk.</p><p>If you don't have stairs in your home, you can often find them outside a local municipal building, train station, or at a high school stadium.</p>
Is Your Walk a True Cardio Workout?<p>Not all walks are equal. A walk that's too leisurely may not provide enough burn to qualify as cardio. To see if you're getting a good workout, try to <a href="https://www.healthline.com/health/how-to-check-heart-rate" target="_blank">measure your heart rate</a> using a monitor.</p><p>"A target goal for a good walking workout heart rate is about 50 to 70 percent of your maximum heart rate," Rue says, adding that maximum heart rate is <a href="https://www.healthline.com/health/fitness-exercise/fat-burning-heart-rate" target="_blank">typically calculated</a> by 220 beats per minute minus your age.</p><p>You can also monitor how easily you can carry on a conversation while you walk to gauge your heart rate.</p><p>"If you can walk and carry on a normal conversation, that's probably a lower intensity walk," says Rue. "If you are slightly breathless but can still have a conversation, that's probably a moderate workout. If you are out of breath and can't talk normally, that's a vigorous workout."</p>
Takeaway<p>By shaking up your routine, you can add excitement to your workout and reap even more rewards than a basic walk provides. Increasing the pace and intensity of a workout will make it more effective.</p><p>Simply pick your favorite variation to add some spice to your next walk.</p>

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.
