Hurricane Matthew Poses Extreme Threat to East Coast
By Bob Henson
After barreling across the Caribbean and through the Bahamas, Hurricane Matthew backed off from an immediate U.S. landfall on Thursday night, and odds were rising that the system might not come fully ashore before looping out to sea over the weekend. In its 11 p.m. EDT advisory, the National Hurricane Center kept Matthew's top sustained winds at 130 mph, making it a minimal Category 4 storm.
Hurricane Hunters found that Matthew's central pressure had dropped to 937 millibars on Wednesday night. Together with radiometer-derived surface winds of 125 mph, it was clear that Matthew remained a potent hurricane, despite its somewhat disheveled appearance on satellite. At 2 a.m. EDT Friday, NHC downgraded Matthew to a Category 3 storm, with top sustained winds of 120 mph.

Eyewall to eyewall
Over the course of Thursday afternoon and evening, Matthew ended up with dual, concentric eyewalls—an outer one, about 10 miles wide, and an inner one, about 70 miles wide, where the strongest winds were focused. The development of dual eyewalls often heralds an eyewall replacement cycle (ERC), in which the inner eyewall collapses and the outer one gradually contracts. Matthew appeared ripe for an ERC on Thursday evening, and that process appeared to be underway late Thursday night, as a reconnaissance summary at 12:15 a.m. EDT Friday reported a single closed eyewall, about 55 miles wide.

A coast-scraping track that could still cause major trouble
What was always recognized as a possibility—that Matthew would never quite make landfall on the Florida coast—emerged as the most likely outcome on Thursday night, as reflected in the 11 p.m. NHC outlook (see Figure 4 above). Matthew's track out of the Bahamas was angled just far enough north of northwest to keep the center rolling more or less parallel to the Florida coast. Provided that Matthew carries out the gradual curve to the right expected late Friday through Saturday, its center will likely remain between about 20 and 50 miles off the coast, perhaps all the way to Charleston, South Carolina, by Saturday night.
This path would be enough to keep Matthew's inner core and its top sustained winds offshore, which is very good news in terms of limiting the most severe wind damage. On the down side, Matthew's outer eyewall—which will likely be packing streaks of 60 to 90 mph sustained winds—will probably edge onto or just inland from the coast early Friday. If Matthew's center remains offshore as the hurricane churns north and northeast toward Georgia, then its outer eyewall may be slower to weaken. People along the Florida coast from around Melbourne northward can expect several hours of high wind on Friday, fierce enough at times to topple trees and power lines. If not catastrophic (thankfully!), such damage may end up being far more widespread on this type of coast-scraping path than it would have been with a hurricane slamming onshore at a right angle.

Hurricane-force winds are possible as far north as coastal Georgia and southern South Carolina later on Friday, but the primary threat here will be high water—the most deadly aspect of U.S. hurricanes. Because of the gradual expansion of Matthew's wind field, its direction of motion, and the largely concave geometry of the coastline, barrier islands and inlets from north FL to southern SC remain at risk of major storm surge even if Matthew remains offshore. Late Thursday night, NHC was projecting the potential for coastal inundations of 7 to 11 feet from Sebastian Inlet, Florida, to Edisto Beach, South Carolina, including parts of the St. Johns River between the coast and Jacksonville. Breaking waves of up to 20 - 25 feet are possible atop the coastal surge.
Time and again in recent years, we've seen hurricanes weaken in terms of peak winds as they approach the coast, yet push far more water onshore than residents expected. This is one reason why the Saffir-Simpson scale no longer directly relates its strength categories to storm surge: peak winds near the center are an unreliable index to how much surge a hurricane may actually produce. Even if Matthew weakens and stays offshore as projected, surge levels in some areas (especially far north Florida and Georgia) may be the highest observed in many decades, and I fear that many coastal residents will underestimate this risk.

Very heavy rainfall is the other water-related threat that still looms large with Matthew. Widespread totals in the 10" to 15" range are projected to fall within about 50 miles of the coast from far north Florida to southeast North Carolina (see Figure 5). The southeast half of the Carolinas can expect 3" to 10" amounts. This may be enough to cause extensive flooding, especially where 10" - 15" of rain has fallen in the last three weeks. With winds potentially gusting to 40 - 50 mph, we can expect extensive tree loss and power outages.
If Matthew fails to make landfall on Friday, or if it does come ashore below Category 3 strength, the remarkable and unprecedented U.S. "drought" in major hurricane landfalls will continue. The last hurricane to strike the U.S. with Category 3 winds was Wilma, in October 2005—nearly 11 years ago.
Beyond the Carolinas
Long-range models agree in turning Matthew gradually seaward from the Carolinas over the weekend, and it now appears that the wacky loop-de-loop solution presented by the models a couple of days ago will materialize, at least in some form or fashion. The path shown in Figure 3 above is one of the most precise and elegant circles I've ever seen in a five-day NHC forecast. By Tuesday, Matthew is predicted to be heading southwestward, back into the northern Bahamas. Matthew will almost certainly be a far weaker system by this point—most likely a tropical storm. It's certainly possible that Matthew will end up crossing Florida at some point next week.

Nicole is now a Category 2 hurricane
Quietly gathering strength while Matthew hogged the spotlight, Hurricane Nicole has become a respectable storm in its own right. Nicole's top sustained winds were bumped up to 105 mph at 11 p.m. EDT Wednesday, making it a strong Category 2 hurricane. Located about 340 miles south of Bermuda, Nicole was stationary, embedded in weak steering currents and in no hurry to head anywhere. Matthew may draw close enough to Nicole early next week to bring the Fujiwhara effect into play, which would tend to push Nicole to the north and Matthew toward the south—consistent with the motions now expected for both systems, although larger-scale steering will probably be the main factor at work.
NHC's Eric Blake provided an interesting climatological tidbit in his Thursday night discussion on Nicole: "This is the first time since September 10, 1964 that two Category 2 (or stronger) hurricanes have occurred simultaneously in the Atlantic basin west of 65W. Interestingly, those hurricanes in 1964, Dora and Ethel, were in similar positions as Matthew and Nicole are now."

In the midst of a pandemic, sales of cleaning products have skyrocketed, and many feel a need to clean more often. Knowing what to look for when purchasing cleaning supplies can help prevent unwanted and dangerous toxics from entering your home.
1. Fragrance – Avoid It<p>One of the fastest ways to narrow down your product options is immediately eliminating any product that promotes a fragrance, or parfum. That scent of "fresh breeze" or lemon might initially smell good, but the fragrance does not last. What does last? The concoction of various undisclosed and unregulated chemicals that created that fragrance.</p><p>Many fragrances contain phthalates, which are linked to many health risks including reproductive problems and cancer.</p>
2. With Bleach? Do Without<p>Going scent-free should have narrowed down your options substantially – now, check the front of the remaining packaging. Any that include ammonia or chlorine bleach ought to go, as these substances are irritating and corrosive to your body. While bleach is commonly known as a powerful disinfectant, there are safer alternatives that you can use in your home, such as sodium borate or hydrogen peroxide.</p><p>While you're at it, check if there are any warnings on the label – "flammable," "use in ventilated area," etc. – if the product is hazardous, that's a red flag and should be avoided.</p>
3. Check the Back Label<p>Flip to the back of the remaining contenders and check out that ingredient list. Less is more, here. Opt for a shorter ingredient list with words you recognize and/or can pronounce.</p><p>You may notice many products do not have ingredient lists – while this doesn't necessarily mean they contain toxic ingredients, transparency is key. Feel free to look up a list online, or stick to products that are open about their ingredients.</p>
4. Ingredients to Avoid<p>We already mentioned that cleaners containing fragrance or parfum, and bleach or ammonia should be avoided, but there are other ingredients to look out for as well.</p><ul><li>Quaternary ammonium "quats" – lung irritants that contribute to asthma and other breathing problems. Also linger on surfaces long after they've been cleaned.</li><li>Parabens – Known hormone disruptor; can contribute to ailments such as cancer</li><li>Triclosan – triclosan and other antibacterial chemicals are registered with the EPA as pesticides. Triclosan is a known hormone disruptor and can also impact your immune system.</li><li>Formaldehyde – Causes irritation of eyes, nose, and throat; studies suggest formaldehyde exposure is linked with certain varieties of cancer. Can be found in products or become a byproduct of chemical reactions in the air.</li></ul>
Cleaning Products and Toxics: The Bottom Line<p>Do your research. There are many cleaning products available, but taking these steps will drastically reduce your options and help keep your home toxic-free. Protecting your home from bacteria and viruses is important, but make sure you do so in a way that doesn't introduce other health risks into the home.</p><p><em>Reposted with permission from </em><em><a href="https://www.ehn.org/how-to-shop-for-cleaning-products-while-avoiding-toxics-2648130273.html" target="_blank">Environmental Health News</a>. </em><a href="https://www.ecowatch.com/r/entryeditor/2649054624#/" target="_self"></a></p>

Returning the ‘Three Sisters’ – Corn, Beans and Squash – to Native American Farms Nourishes People, Land and Cultures
By Christina Gish Hill
Historians know that turkey and corn were part of the first Thanksgiving, when Wampanoag peoples shared a harvest meal with the pilgrims of Plymouth plantation in Massachusetts. And traditional Native American farming practices tell us that squash and beans likely were part of that 1621 dinner too.
Abundant Harvests<p>Historically, Native people throughout the Americas bred indigenous plant varieties specific to the growing conditions of their homelands. They selected seeds for many different traits, such as <a href="https://emergencemagazine.org/story/corn-tastes-better/" target="_blank" rel="noopener noreferrer">flavor, texture and color</a>.</p><p>Native growers knew that planting corn, beans, squash and sunflowers together produced mutual benefits. Corn stalks created a trellis for beans to climb, and beans' twining vines secured the corn in high winds. They also certainly observed that corn and bean plants growing together tended to be healthier than when raised separately. Today we know the reason: Bacteria living on bean plant roots pull nitrogen – an essential plant nutrient – from the air and <a href="http://www.tilthalliance.org/learn/resources-1/almanac/october/octobermngg" target="_blank" rel="noopener noreferrer">convert it to a form that both beans and corn can use</a>.</p><p>Squash plants contributed by shading the ground with their broad leaves, preventing weeds from growing and retaining water in the soil. Heritage squash varieties also had spines that discouraged deer and raccoons from visiting the garden for a snack. And sunflowers planted around the edges of the garden created a natural fence, protecting other plants from wind and animals and attracting pollinators.</p><p>Interplanting these agricultural sisters produced bountiful harvests that sustained large Native communities and <a href="http://dx.doi.org/10.1353/eam.2015.0016" target="_blank">spurred fruitful trade economies</a>. The first Europeans who reached the Americas were shocked at the abundant food crops they found. My research is exploring how, 200 years ago, Native American agriculturalists around the Great Lakes and along the Missouri and Red rivers fed fur traders with their diverse vegetable products.</p>
Displaced From the Land<p>As Euro-Americans settled permanently on the most fertile North American lands and acquired seeds that Native growers had carefully bred, they imposed policies that <a href="https://doi.org/10.1086/ahr/87.2.550" target="_blank">made Native farming practices impossible</a>. In 1830 President Andrew Jackson signed the <a href="https://guides.loc.gov/indian-removal-act" target="_blank">Indian Removal Act</a>, which made it official U.S. policy to force Native peoples from their home locations, pushing them onto subpar lands.</p><p>On reservations, U.S. government officials discouraged Native women from cultivating anything larger than small garden plots and pressured Native men to practice Euro-American style monoculture. Allotment policies assigned small plots to nuclear families, further limiting Native Americans' access to land and preventing them from using communal farming practices.</p><p>Native children were forced to attend boarding schools, where they had no opportunity to <a href="https://doi.org/10.5749/jamerindieduc.57.1.0145" target="_blank">learn Native agriculture techniques or preservation and preparation of Indigenous foods</a>. Instead they were forced to eat Western foods, turning their palates away from their traditional preferences. Taken together, these policies <a href="https://kansaspress.ku.edu/978-0-7006-0802-7.html" target="_blank" rel="noopener noreferrer">almost entirely eradicated three sisters agriculture</a> from Native communities in the Midwest by the 1930s.</p>
Reviving Native Agriculture<p>Today Native people all over the U.S. are working diligently to <a href="https://www.oupress.com/books/15107980/indigenous-food-sovereignty-in-the-united-sta" target="_blank" rel="noopener noreferrer">reclaim Indigenous varieties of corn, beans, squash, sunflowers and other crops</a>. This effort is important for many reasons.</p><p>Improving Native people's access to healthy, culturally appropriate foods will help lower rates of <a href="https://www.cdc.gov/vitalsigns/aian-diabetes/index.html" target="_blank">diabetes</a> and <a href="https://www.apa.org/pi/oema/resources/ethnicity-health/native-american/obesity" target="_blank">obesity</a>, which affect Native Americans at disproportionately high rates. Sharing traditional knowledge about agriculture is a way for elders to pass cultural information along to younger generations. Indigenous growing techniques also protect the lands that Native nations now inhabit, and can potentially benefit the wider ecosystems around them.</p>

Amid reports that oil industry-friendly former Energy Secretary Ernest Moniz remains under consideration to return to his old post in the incoming Biden administration, a diverse coalition of environmental groups is mobilizing for an "all-out push" to keep Moniz away from the White House and demand a cabinet willing to boldly confront the corporations responsible for the climate emergency.
