The weather's gotten cooler. Daylight savings time is behind us so we've got longer, darker evenings ahead of us. And winter is coming, along with flu and cold season.
Hot tea in all its varieties is one of winter's compensations.

But there are compensations. On a blustery day, there's nothing better than curling up on the couch, wrapped in a blanket, with a good book, an affectionate pet—and a steaming cup of tea. It warms your belly, it warms your hands—and that cup can contain all kinds of great health benefits that can help you get through the winter feeling good.
What are some of the things hot tea can do for you?
1. Tea is a heady brew of hundreds of natural chemicals, many of them beneficial or even essential to health. Foremost among them are polyphenols, a form of antioxidant flavonoids. These are essential for cell regeneration and staving off the effects of aging, including conditions like heart disease, cancer and possibly even Alzheimer's. Tea has been associated with a lower incidence of Parkinson's disease as well. It's not a miracle elixir but it can help strengthen the body's defenses against the ravages of time.
2. Tea has been shown to have an impact on oral health and have cavity-fighting properties. Studies have shown that the polyphenols found in black tea can inhibit the growth of bacteria in your mouth and help prevent plaque buildup.
3. Although tea does have some caffeine, it doesn't have nearly as much as coffee. So while it can be a mild stimulant and give you a little jolt of energy and mental alertness, it isn't going to put you as much on edge as too much coffee might and it's not as likely to keep you up all night—depending on how much you drink, of course, and how close to bedtime.
4. Different teas—white, green, black and oolong—have different benefits. Green tea, for instance, may build bone density, making your bones stronger. And white and green teas, the least processed, retain more of their flavonoids and have even greater cancer-fighting properties. Herbal infusions are not actually teas, but may have a range of health benefits of their own, including settling an upset stomach, helping you fall asleep or relieving constipation.
5. Tea, especially oolong teas, have been associated with boost in metabolism, leading to potential weight loss. A couple of studies have shown that oolong tea drinkers have smaller waist sizes.
6. Ladling in the refined white sugar will certainly counteract any possible weight loss, and it isn't a good idea for a lot of reasons. But other traditional tea go-withs, like lemon and honey, bring potential health assets of their own. Honey has traces of vitamin and minerals and a bunch of antioxidants of its own. If you feel a sore throat coming on, it coats the throat and soothes it. The vitamin C in lemon is another antioxidant that gives a boost to the immune system and helps fight off seasonal bugs. So there really is something to that prescription of a cup of hot tea with honey and lemon when you've got the winter blahs.

At a time of impending global food scarcity, cell-based meats and seafood have been heralded as the future of food.
<p>This cell-based industry is where scientists, environmentalists and food technology companies intersect to offer more sustainable ways to feed the world's growing population. The high-tech food innovations take "the animal out of the meat" and create "seafood without the sea," respectively coined by <a href="https://newatlas.com/lab-grown-meat-public-attitudes/48921/?itm_source=newatlas&itm_medium=article-body" target="_blank">New Atlas</a> and <a href="https://www.npr.org/sections/thesalt/2019/05/05/720041152/seafood-without-the-sea-will-lab-grown-fish-hook-consumers" target="_blank">NPR</a>. These products — real meat and seafood — are originally cultured from animal cells but made without the actual animal. Because of this, many of the personal and global concerns about safety, ethics and the environment can be avoided without sacrificing food preferences.</p><p>Two leading industry examples are Eat Just and BlueNalu. Last month, Singapore issued San Francisco-based Eat Just the <a href="https://www.ecowatch.com/lab-grown-chicken-approved-singapore-2649108790.html" target="_self">world's first regulatory approval for cell-based meat</a>. The "chicken nuggets" are now available at downtown Singapore restaurant 1880. Meanwhile, San Diego's BlueNalu has pioneered "cellular aquaculture" to create cell-based seafood fillets from fish, including yellowtail, mahi-mahi, red snapper and tuna. In mid-2020, the company increased its research and development facilities six-fold after completing a $20 million funding round, <a href="https://thefishsite.com/articles/blue-nalu-set-for-6-fold-expansion" target="_blank">The Fish Site</a> reported. These two companies are pushing the industry to the next level with key regulatory developments and new innovations.</p><h3>The Science Behind Cell-Based</h3><p>In a nutshell, this is how cell-based food works: muscle stem cells are obtained from an actual animal, like chicken or fish, and cultivated in steel tanks with the same nutrients that living animals consume. The goal is not to grow a full animal, so the end result doesn't include the head, tail or heart, for example, while the original cell donor isn't sacrificed. The harvested cells multiply and are shaped to form meat or fish that cooks, looks and tastes just like its real counterpart.</p><p>"The process is somewhat like culturing a beer. At the end of the process, you have chicken meat," Eat Just CEO Josh Tetrick told <a href="https://www.bloomberg.com/news/videos/2021-01-11/would-you-eat-lab-grown-meat-video" rel="noopener noreferrer" target="_blank">Bloomberg</a>.</p><p>BlueNalu's President and CEO Lou Cooperhouse agreed, telling EcoWatch, "We aren't making a living being, it's just a fish fillet. It's live tissue until we freeze it. Then it's no longer live; it's the product you might have and consume every day."</p>
<h3>The Taste</h3><p>But how does it really taste? Identical to what consumers are used to, both companies told EcoWatch.</p><p>Cooperhouse described how his company mimics the "mouth feel" of conventional fish by recreating the same proportions of muscle, fat and connective tissue in their cell-based fillets. The company uses starter cells to grow all three types of tissue and then combines them to create the same exact product that consumers are used to eating.</p><p>"We're creating identical mahi-mahi to conventional mahi-mahi, from a sensory perspective and a functional perspective," Cooperhouse told EcoWatch. "When you cook it, it smells like fish. You can fry it, bake it, saute it. It caramelizes. It has all the same characteristics as fish, because it is fish. We just made it out of the body. We made it in steel tanks."</p><p>Andrew Noyes, head of global communications for Eat Just, similarly said that their chicken product "cooks, looks and tastes like chicken," including the flavor profile and texture, "because it is chicken."</p>
<h3>The Many Advantages of Cultured Foods</h3><p>Both companies emphasized how cell-based foods don't require killing animals or adding growth hormones or antibiotics. Cell-based food also removes the environmental impact of industrial farming and commercial fishing. This "critical overlay of benefits at every level" creates a new solution for global supply chains that supports biodiversity and the planet's health, Cooperhouse said.</p><p>"We want consumers to know our fillets are different in these ways," Cooperhouse added. "They're not wild, not farmed." On a <a href="https://medium.com/eat-blue/not-wild-not-farmed-but-what-should-we-call-our-seafood-made-from-fish-cells-136fa0343b4d" rel="noopener noreferrer" target="_blank">company blog</a>, Cooperhouse said that BlueNalu's products are a third alternative way to enjoy fish that is "as delicious and nutritious as their wild-caught or farm-raised counterparts... but without the mercury, microplastics or other pollutants that might be associated with conventional seafood."</p><p>Tetrick also emphasized the safety advantage of cultured meat over conventional. "This way of making meat radically decreases the probability of zoonotic diseases through our food system," he told Bloomberg, because it avoided pathogens like E. coli and salmonella, as well as sanitization concerns.</p><p>The environmental benefits of cell-cultured meat also mean less environmental destruction. Conventional <a href="https://www.ecowatch.com/tag/meat-consumption" target="_self">meat production</a> requires massive amounts of land for grazing and food production. Just growing feed for livestock <a href="https://www.ecowatch.com/meat-consumption-2021-2649770271.html">uses 71 percent of global arable land</a> and <a href="https://www.ecowatch.com/amazon-rainforest-collapse-2649776959.html#:~:text=The%20future%20of%20the%20world's,dry%2C%20shrubby%20plain%20by%202064." target="_self">drives Amazonian deforestation</a>.</p>
<p>"Chicken is the world's most consumed (and fastest growing) meat," Noyes told EcoWatch. "Chickens also consume more feed collectively than other farmed animals. Today, more than one-third of the ice-free land on Earth and tens of millions of acres of rainforest teeming with our planet's most diverse life forms have been replaced with fields of chicken feed."</p><p>According to the <a href="http://www.fao.org/documents/card/en/c/I9540EN" rel="noopener noreferrer" target="_blank">Food and Agriculture Organization of the United Nations</a>, 60 percent of the world's fisheries are fully fished, or at maximum output capacity, and 33 percent are overfished. Additionally, in the last half-century, oceanic <a href="https://www.ecowatch.com/tag/dead-zones" target="_self">dead zones</a> have quadrupled due to fishing and the <a href="https://www.ecowatch.com/climate-change/" target="_self">climate crisis</a>, reported <a href="https://bigthink.com/technology-innovation/lab-grown-fish?rebelltitem=2#rebelltitem2" rel="noopener noreferrer" target="_blank">Big Think</a>. <a href="https://www.ecowatch.com/tag/fish-farms" target="_self">Fish farming</a>, once thought to be a solution to declining wild fish populations, <a href="https://www.ecowatch.com/industrial-agriculture-problems-boycott-2554509022.html" target="_self">brings its own issues</a>, including the loss of critical mangrove habitat and the proliferation of sea lice and other diseases from farms, which escape and kill wild fish, <a href="https://www.seafoodwatch.org/seafood-basics/sustainable-solutions/preserve-habitats#:~:text=The%20exponential%20growth%20of%20aquaculture,the%20local%20people%20and%20ecosystems." rel="noopener noreferrer" target="_blank">Seafood Watch</a> reported.</p><p>Cell-based seafood won't put pressure on these depleted stocks and fragile habitats and will also avoid bycatch, a serious threat to biodiversity when unintentionally fished creatures are injured or killed.</p><p><a href="https://www.ecowatch.com/beef-and-climate-change-2634244134.html" target="_blank">Meat production</a> is also energy-intensive and generates vast amounts of methane and other greenhouse gases. Cell-based foods are more carbon efficient and climate-friendly than conventional meat and seafood because of production efficiency and a localized distribution plan.</p><p>"If you look at climate change, this way of making meat is 90 percent more carbon-efficient than the typical approach," Tetrick told Bloomberg.</p><p>BlueNalu is preparing to scale for global cities to house 150,000-square-foot facilities, each capable of producing enough cell-based seafood to feed more than 10 million local residents, NPR reported. This way, cell-based seafood will avoid greenhouse gas emissions caused by shipping.</p>
<p>Finally, waste is reduced because these companies are only growing the animal parts to be consumed. Traditionally, cattle are inefficient, requiring five to 20 pounds of plant-based feed to create one pound of conventional beef, <a href="https://www.cnet.com/news/beyond-the-impossible-meat-grown-from-cells-better-for-planet-if-you-will-eat-it/" rel="noopener noreferrer" target="_blank">CNet</a> reported. <a href="https://www.scientificamerican.com/article/lab-grown-meat/" target="_blank">Scientific American</a> estimated that one tissue sample from a cow could yield enough muscle tissue to make 80,000 quarter-pounders.<br></p><p>Cooperhouse estimated that a typical fish would produce a 60 percent yield after cutting off the head and tail and removing the skin and bones, whereas his fillets yield 100 percent.</p><p>"It's a total paradigm shift from an environmental and sustainability perspective," he told EcoWatch. "All that freight, oil, labor, dry ice, foam coolers — all goes away."</p><p>The consistency of quality, readily available products has also garnered interest from foodservice operators, Cooperhouse said. Having a stable supply available year-round will help restaurants combat the variability they currently experience.</p>
<h3>Challenges</h3><p>The big question is whether or not the general public will eat the products, once available.</p><p>"If there's an ick factor to cell-based fish, remember that most processed foods are already created in laboratories," argued Big Think. "There are no Oreo trees or ketchup plants to harvest."</p><p>A University of Queensland survey found that a majority of respondents would try the products, but less would eat them regularly or see them as conventional meat replacements, <a href="https://newatlas.com/lab-grown-meat-public-attitudes/48921/?itm_source=newatlas&itm_medium=article-body" rel="noopener noreferrer" target="_blank">New Atlas</a> reported. Respondents reported that taste would be a driving factor in favor of cell-based foods.</p><p>Cost is the other issue. For Eat Just, their products are competitively priced with premium chicken, although they foresee a pathway for a cheaper price within the next five years, Tetrick told Bloomberg. BlueNalu doesn't yet have a price point for their inaugural mahi-mahi fillet, but are aggressively partnering with known brands and distributors to lower costs.</p><h3>What's Next</h3><p>Singapore's approval of Eat Just's nugget is paving the way for other companies and nations to follow suit, <a href="https://www.theguardian.com/environment/2020/dec/02/no-kill-lab-grown-meat-to-go-on-sale-for-first-time" target="_blank">The Guardian reported</a>. Both Eat Just and BlueNalu are actively engaging regulators in the U.S. and other countries to bring their products online as quickly and safely as possible. Since the products are not genetically modified, "the approval will be about whether this is safe, clean, and are the manufacturing processes reliable and accountable," Cooperhouse told NPR.</p><p>While not a substitute for all conventional food, if cell-based meats and seafood are scaled up and accepted, <a href="https://www.ecowatch.com/meat-consumption-predictions-vegan-lab-2638801931.html" target="_self">many hope to feed the world's anticipated 9.5 billion people</a> without stripping the planet bare and ruining the climate.</p><p>"The simplest way to think about it is it allows all of us to consume meat, the good part, the nutritional composition, the taste, and do away with the bad part, which is the killing, the environmental deforestation, the acceleration of zoonotic disease, and we can still have a fried chicken," Tetrick told Bloomberg.</p>

One city in New Zealand knows what its priorities are.
Dunedin, the second largest city on New Zealand's South Island, has closed a popular road to protect a mother sea lion and her pup, The Guardian reported.
<p>"We've closed John Wilson Ocean Drive to vehicles for the next month to allow some special residents to use the road safely - a New Zealand sea lion and her pup have taken up residence at the golf course next door and are regularly crossing the road to get to the beach," the Dunedin City Council wrote in a <a href="https://www.facebook.com/DunedinCityCouncil/posts/3687384977973820" rel="noopener noreferrer" target="_blank">Facebook Post Monday</a>.</p>
<div class="rm-shortcode" data-rm-shortcode-id="30b8c8ee5783728b66f03a8cd2d1ab14"><div class="fb-post" data-href="https://www.facebook.com/DunedinCityCouncil/photos/a.226655984046754/3687384087973909/"></div></div>
<p>The council said that residents could still walk or ride bikes in the area, but should stay at least 20 meters (approximately 66 feet) away from the sea lions at all times and keep any dogs on a leash.</p><p>The mother sea lion, named Hiriwa, was first spotted on the Chisholm Links golf course about a week ago and is now nesting with her pup in a bush near the 13th hole, <a href="https://www.rnz.co.nz/news/national/434504/sea-lion-makes-itself-at-home-on-dunedin-golf-course" target="_blank">Radio New Zealand reported</a>.</p>
<div class="rm-shortcode" data-rm-shortcode-id="e202b1bbdd1c522d83b85cc7b36dba2c"><div class="fb-post" data-href="https://www.facebook.com/ChisholmLinks/photos/pcb.3417932631666520/3417899185003198"></div></div>
<p>This is her fifth pup, Department of Conservation (DOC) coastal Otago <a href="https://www.ecowatch.com/tag/biodiversity" target="_self">biodiversity</a> ranger Jim Fyfe said.<br></p><p>"She has come up John Wilson Drive and into the golf course to have her pup in some bushes there," he told Radio New Zealand.</p><p>Fyfe also told the <a href="https://www.nzherald.co.nz/nz/dunedin-road-temporarily-closed-for-sea-lion-and-pup/XMOZAJTUISN7OCIRS6H7OSGPHY/" rel="noopener noreferrer" target="_blank">New Zealand Herald</a> that the pup was born Thursday, Jan. 7 and immediately made its presence known by making lots of noise.</p><p>The mother and pup will now spend about a month nesting before heading out to sea, Fyfe explained. During that time, the mother will need to walk 500 meters (approximately 1,640 feet) to the beach each day to feed. On these journeys, she will think to avoid male sea lions, but she won't be thinking about cars, people or dogs. That is why the road closure is so important, Fyfe explained.</p>
<p>Local residents have responded favorably to the council's decision, The Guardian reported.</p><p>"Awesome! Love our little country in this way," one commenter wrote on Facebook.</p><p>The golf course has also welcomed its new residents.</p><p>"We're lucky to have marine mammals on our coastline and we need to share the space with them, as this is what makes our coastal Links and Dunedin's coastline so unique!" it wrote in a <a href="https://www.facebook.com/ChisholmLinks/posts/3417932631666520" target="_blank">Jan. 5 Facebook post</a>.</p>
<div class="rm-shortcode" data-rm-shortcode-id="9524a27c929e225c2fe012fe759f48b4"><div class="fb-post" data-href="https://www.facebook.com/ChisholmLinks/photos/pcb.3417932631666520/3417892388337211/"></div></div>
<p>New Zealand sea lions are an <a href="https://www.ecowatch.com/tag/endangered-species" target="_self">endangered species</a> and one of the rarest species of sea lions in the world, the city council noted. There are around 12,000 left in the world, according to DOC figures reported by <a href="https://www.cnn.com/travel/article/new-zealand-sea-lions-road-closure-scli-intl/index.html" target="_blank">CNN</a>. Killing one can bring a penalty of up to two years in prison or a fine of up to $178,000.</p><p>Dunedin's 120,000 residents are used to road closures to protect <a href="https://www.ecowatch.com/tag/wildlife" target="_self">wildlife</a>, but usually these closures last for a day rather than a month, The Guardian explained. The city is also used to welcoming breeding sea lions since 1993, and their numbers in the city have increased since <a href="https://www.ecowatch.com/tag/conservation" target="_self">conservation</a> efforts intensified.</p><p>Despite this, the overall breeding population of New Zealand sea lions is still falling. The main threats to the species are fishing, disease, human activity and lack of food.</p><p>Still, this is shaping up to be a good year for sea lions in Dunedin.</p><p>"This year we expect 20 sea lions around Dunedin to give birth. This is going to be a record number for us," Fyfe told Radio New Zealand. "New Zealand sea lions are a threatened species that is just recovering on the mainland coastline, so it's really good news."</p>

In an alarming new study, scientists found that climate change is already harming children's diets.
<p>It has long been understood that climate change will impact diet and food security globally. But up until now, little research proved how diet diversity is impacted by climate change outcomes, like warmer temperatures and increased precipitation, over a span of geographical areas.</p><p>Led by researchers at the University of Vermont, the study surveyed the diets of more than 107,00 children under the age of five, across 19 countries in Asia, Africa, and South America, with 30 years of precipitation and temperature data, according to the <a href="https://iopscience.iop.org/article/10.1088/1748-9326/abd0ab" target="_blank">study</a>.</p>
<p>Higher, long-term temperatures were associated with decreased diet diversity among children. "It surprised us that higher temperatures are already showing an impact," Meredith Niles, the study's lead author and an assistant professor of Nutrition and Food Sciences at the University of Vermont, said in an <a href="https://www.uvm.edu/gund/news/climate-change-hurting-childrens-diets-global-study-finds-0" target="_blank">article</a>.</p><p>In 2019, over 144 million children under the age of five were malnourished, <a href="https://data.unicef.org/topic/nutrition/malnutrition/#:~:text=In%202019%2C%2021.3%20per%20cent,5%20worldwide%20had%20stunted%20growth.&text=Between%202000%20and%202019%2C%20stunting,199.5%20million%20to%20144.0%20million." target="_blank">according to data by the UNICEF</a>. This number could have grown by an additional 6.7 million in 2020 alone, exacerbated by the COVID-19 pandemic, according to a <a href="https://www.unicef.org/press-releases/unicef-additional-67-million-children-under-5-could-suffer-wasting-year-due-covid-19" target="_blank" rel="noopener noreferrer">report published in July</a>.</p>
<p>In the study, researchers used a scale developed by the United Nations to understand intakes of micronutrients like iron, folic acid, zinc and vitamins A and D.</p><p>On average children ate 3.2 out of 10 food groups. But in "emerging economies" like in China, children ate 6.8 out of 10 food groups, more than doubling the overall average, according to the <a href="https://www.uvm.edu/gund/news/climate-change-hurting-childrens-diets-global-study-finds-0" target="_blank" rel="noopener noreferrer">University of Vermont</a>. Household wealth, consequently, was the biggest factor in children's diet diversity, <a href="https://www.reuters.com/article/global-climate-food/scientists-warn-climate-change-is-harming-childrens-diets-idUSL8N2JO4P4" target="_blank" rel="noopener noreferrer">Reuters reported</a>.</p><p>"These results suggest that, if we don't adapt, climate change could further erode a diet that already isn't meeting adequate child micronutrient levels," Brendan Fisher from UVM's Rubenstein School of Environment and Natural Resources <a href="https://www.uvm.edu/gund/news/climate-change-hurting-childrens-diets-global-study-finds-0" target="_blank">said</a> about children's diets in developing countries.</p>
<p>Although the study proved what researchers had long expected regarding warming temperatures, they did find surprising results on how precipitation alters diet diversity.</p><p>Higher precipitation, linked to countries in West and Southeast Africa and Central America, was associated with higher diversity in children's diet, the University of Vermont <a href="https://www.uvm.edu/gund/news/climate-change-hurting-childrens-diets-global-study-finds-0" target="_blank">reported</a>.</p><p>"Higher rainfall in the future may provide important diet quality benefits in multiple ways, but it also depends on how that rain comes," Molly Brown, a co-author of the study <a href="https://www.uvm.edu/gund/news/climate-change-hurting-childrens-diets-global-study-finds-0" target="_blank" rel="noopener noreferrer">said</a>. "If it's more erratic and intense, as is predicted with climate change, this may not hold true."</p><p>Changes in the agriculture and the food industry can also be linked to worsening diets, Paolo Vineis of Imperial College London, who studies the effects of climate change on the disease, <a href="https://www.reuters.com/article/global-climate-food/scientists-warn-climate-change-is-harming-childrens-diets-idUSL8N2JO4P4" target="_blank" rel="noopener noreferrer">told Reuters</a>.</p><p>By 2050, global demand for food may increase by 59 to 98 percent from a larger population. Although this will require major agricultural and food industries to rapidly expand their production, droughts and higher temperatures will threaten their ability to do so, <a href="https://blogs.ei.columbia.edu/2018/07/25/climate-change-food-agriculture/" target="_blank" rel="noopener noreferrer">Columbia University's Earth Institute reported</a>.</p>
<p>In the United States alone, for example, the production of corn, which is used to feed livestock, could decrease by 50 percent if the planet warms by four degrees Celsius, <a href="https://www.pnas.org/content/115/26/6644" target="_blank" rel="noopener noreferrer">a study found</a>, a likely temperature increase predicted for 2100.</p><p>So what kind of solutions can help?</p><p>Educating investors on the financial risks and potential opportunities of the climate crisis could help the food industry adapt to the climate impacts already being felt, Columbia University's Earth Institute <a href="https://blogs.ei.columbia.edu/2018/07/25/climate-change-food-agriculture/" target="_blank" rel="noopener noreferrer">reported</a></p><p>"Food security is going to be one of the most pressing climate-related issues, mainly because most of the world is relatively poor and food is going to become increasingly scarce and expensive," Peter De Menocal, founding director of Columbia's Center for Climate and Life, <a href="https://blogs.ei.columbia.edu/2018/07/25/climate-change-food-agriculture/" target="_blank" rel="noopener noreferrer">told Columbia's Earth Institute</a>.</p><p>As for improving diets globally, researchers at the University of Vermont <a href="https://iopscience.iop.org/article/10.1088/1748-9326/abd0ab" target="_blank" rel="noopener noreferrer">stress</a> the need for more research aimed at protecting children's nutrition especially for "vulnerable populations in low and middle-income countries across the tropics where the most profound climate changes are expected."</p>

Earth had its second-warmest year on record in 2020, just 0.02 degrees Celsius (0.04°F) behind the record set in 2016, and 0.98 degrees Celsius (1.76°F) above the 20th-century average, NOAA reported January 14.
<p><a href="https://data.giss.nasa.gov/gistemp/tabledata_v4/GLB.Ts+dSST.txt" target="_blank" rel="noopener noreferrer">NASA</a> and the <a href="https://climate.copernicus.eu/copernicus-global-november-temperatures-reached-record-high-while-europe-experienced-its-warmest" target="_blank" rel="noopener noreferrer">European Copernicus Climate Change Service</a> rated 2020 as tied with 2016 as the warmest year on record (NASA rates the margin of error at .05 degrees C); the <a href="https://ds.data.jma.go.jp/tcc/tcc/products/gwp/temp/nov_wld.html" target="_blank" rel="noopener noreferrer">Japan Meteorological Agency</a> rated 2020 as the warmest year on record. Minor differences in rankings often occur among various research groups, the result of different ways they handle data-sparse regions such as the Arctic.</p>

Figure 1. Departure of temperature from average for 2020, the second-warmest year the globe has seen since record-keeping began in 1880, according to NOAA. Record-high annual temperatures over land and ocean surfaces were measured across parts of Europe, Asia, southern North America, South America, and across parts of the Atlantic, Indian, and Pacific oceans. No land or ocean areas were record cold for the year. NOAA National Centers for Environmental Information
<p>The remarkable global warmth of 2020 means that the seven warmest years on record since 1880 were the most recent seven years — 2014 through 2020. The near-record global warmth in 2020 is all the more striking since it occurred during the minimum of the weakest solar cycle in more than 100 years and during a year without a strong El Niño. Record-warm global temperatures typically occur during strong El Niño events and when the solar cycle is near its maximum. The warmth of 2020 is a testament to how significantly human-caused global warming is heating the planet.</p>

<h4>Warmest Year on Record for Total Ocean Heat Content</h4><p>Despite the presence of a prominent La Niña event that began in August, the total heat content of the world's oceans in 2020 was the warmest in recorded human history, according to a January 13, 2021 paper by Cheng <em>et al.</em>, <a href="https://link.springer.com/article/10.1007/s00376-021-0447-x" target="_blank" rel="noopener noreferrer">Upper Ocean Temperatures Hit Record High in 2020</a>, published in <em>Advances in Atmospheric Sciences</em>. In the uppermost 2,000 meters of the oceans, there were 211 to 234 zettajoules more heat in 2020 than the 1981-2010 average, and 2020 had 1 to 20 zettajoules more ocean heat content than in 2019 (a zettajoule is one sextillion joules — ten to the 21st power). For comparison, in 2010, humans <a href="https://twitter.com/johncarlosbaez/status/1216783686957297672?lang=en" target="_blank" rel="noopener noreferrer">used</a> a total of 0.5 zettajoules of energy.</p><p>More than 90% of the increasing heat from human-caused global warming accumulates in the ocean because of its large heat capacity. The remaining heating manifests as atmospheric warming, a drying and warming landmass, and melting land and sea ice. Increasing ocean heat content causes sea-level rise through thermal expansion of the water and melting of glaciers in contact with the ocean. It also produces stronger and more rapidly intensifying hurricanes; causes more intense precipitation events that can lead to destructive flooding; contributes to "marine heat waves" that damage or destroy coral reefs; and disrupts atmospheric circulation patterns.</p>
<h4>A Slew of Heat Records in 2020</h4><p>International records researcher <a href="https://twitter.com/extremetemps" target="_blank" rel="noopener noreferrer">Maximiliano Herrera</a> keeps the pulse of the planet in remarkable detail, and he logged 11 nations or territories that set or tied their all-time heat records in 2020. That total fell far short of the record of 24 such records in 2019. No nations or territories set or tied an all-time cold record in 2020. Here are the all-time heat records set in 2020:</p><p>Colombia: 42.6°C (108.7°F) at Jerusalem, February 19 (tie);<br>Ghana: 44.0°C (111.2°F) at Navrongo, April 6;<br>Cuba: 39.2°C (102.6°F) at Palo Seco, April 10; broken again April 11 with 39.3°C (102.7°F) at Veguitas, and again on April 12 with 39.7°C (103.5°F) at Veguitas;<br>Mayotte, France department: 36.4°C (97.5°F) at Trevani, April 14;<br>Taiwan: 40.5°C (104.9°F) at Taimali Research Center, July 16;<br>Lebanon: 45.4°C (113.7°F) at Houche Al Oumara, July 27;<br>United States: 54.4°C (129.9°F) at Death Valley, California, August 16;<br>Japan: 41.1°C (106.0°F) at Hamamatsu, August 17;<br>Dominica: 35.7°C (96.3°F) at Canefield Airport, September 15;<br>Puerto Rico (U.S. territory): 37.8°C (100.0°F ) at Aguirre, September 17; and<br>Paraguay: 45.5°C (113.9°F ) at Pozo Hondo, September 26.</p><p>Among global weather stations having at least 40 years of record-keeping, Herrera documented 348 that exceeded their all-time heat record in 2020; only eight stations with a long-term period of record set an all-time cold record in 2020. For comparison, 632 stations set their all-time heat record in 2019 and 11 their all-time cold record.</p>
<h4>Notable Global Heat and Cold Records for 2020</h4><p>Hottest temperature in the Northern Hemisphere: 54.4°C (129.9°F) at Death Valley, U.S., August 16;<br>Coldest temperature in the Northern Hemisphere: -66.0°C (-86.8°F) at Summit, Greenland, January 2;<br>Hottest temperature in the Southern Hemisphere: 48.9°C (120.0°F) at Penrith Lakes, Australia, January 4;<br>Coldest temperature in the Southern Hemisphere: -80.8°C (-113.4°F) at Dome Fuji, Antarctica, August 16;<br>Highest 2020 average temperature worldwide: 31.5°C (88.7°F) at Yelimane, Mali, and Matam, Senegal; and<br>Highest 2020 average temperature in the Southern Hemisphere: 29.8°C (85.6°F) at Surabaya Airport, Indonesia, and Wyndham, Australia.</p><p>Earth's record for hottest yearly average temperature was 32.9°C (91.2°F) at Makkah, Saudi Arabia, in 2010 and 2016.</p>
<h4>126 Additional Monthly National/Territorial Heat Records Beaten or Tied</h4><p>In addition to the 11 all-time national heat records, 126 other national monthly heat records were set in 2020, for a total of 137 national monthly heat records:</p><p>– January (13): Norway, South Korea, Angola, Congo Brazzaville, Dominica, Mexico, Indonesia, Guinea Bissau, Gambia, Sao Tome and Principe, Cuba, British Indian Ocean Territory, Singapore;<br>– February (12): Spain, Antarctica, Azerbaijan, Costa Rica, The Bahamas, Switzerland, Maldives, Gambia, Russia, Seychelles, Dominican Republic, U.S. Virgin Islands;<br>– March (7): Paraguay, Cabo Verde, Mozambique, Seychelles, United States, Thailand, Northern Mariana Islands;<br>– April (14): Paraguay, Niger, St. Barthelemy, Honduras, Guernsey, Haiti, Congo Brazzaville, Kyrgyzstan, Mongolia, China, Saba, Northern Mariana Islands, U.S. Virgin Islands, Dominican Republic;<br>– May (10): Niger, Greece, Saba, Cyprus, Solomon Islands, Turkey, Haiti, Kazakhstan, Chile, Uzbekistan;<br>– June (6): Maldives, Thailand, U.S. Virgin Islands, Saba, Kenya, Ghana;<br>– July (7): Mozambique, U.S. Virgin Islands, Laos, Myanmar, Iran, Saudi Arabia, Northern Mariana Islands;<br>– August (6): Solomon Islands, Mexico, Australia, Cocos Islands, Paraguay, U.S. Virgin Islands;<br>– September (18): Laos, Taiwan, Japan, Turkey, Lebanon, Israel, Jordan, Cyprus, Mexico, Belgium, Netherlands, Luxembourg, Botswana, St. Barthelemy, Mayotte, Argentina, Brazil, British Indian Ocean Territory;<br>– October (11): Algeria, Brazil, Tunisia, Turkey, Cyprus, Jordan, Peru, Myanmar, Northern Marianas Islands, Botswana, Maldives;<br>– November (11): Luxembourg, Finland, Nepal, Mexico, Aland Islands, Sweden, Maldives, Northern Marianas, Taiwan, Swaziland, Sudan; and<br>– December (11): Mexico, Ghana, Pakistan, Algeria, Qatar, Maldives, Niger, Taiwan, Dominica, Falkland Islands, South Georgia and the Sandwich Islands.</p>
<h4>One Monthly National/Territorial Cold Record Beaten or Tied in 2020</h4><p>– April: St. Eustatius.<br></p><p>An October monthly record reported in Aruba was judged to be unreliable.</p>

<h4>December 2020: Earth's Eighth-Warmest December on Record</h4><p>December 2020 was the eighth-warmest December since global record-keeping began in 1880, NOAA's <a href="https://www.ncdc.noaa.gov/sotc/global/202007" target="_blank" rel="noopener noreferrer">National Centers for Environmental Information</a> reported January 14. NASA and the <a href="https://climate.copernicus.eu/monthly-climate-bulletins" target="_blank" rel="noopener noreferrer">European Copernicus Climate Change Service</a> rated the month as the sixth-warmest December on record, and the <a href="https://ds.data.jma.go.jp/tcc/tcc/products/gwp/temp/nov_wld.html" target="_blank" rel="noopener noreferrer">Japan Meteorological Agency</a> rated it as the tenth-warmest. Again: Minor differences in rankings often occur among various research groups, the result of different ways they handle data-sparse regions such as the Arctic.</p>

Figure 3. Departure of sea surface temperature from average in the benchmark Niño 3.4 region of the eastern tropical Pacific (5°N-5°S, 170°W-120°W). Sea surface temperature were approximately one degree Celsius below average over the past month, characteristic of moderate La Niña conditions. Tropical Tidbits
<h4>A Moderate La Niña Event Continues</h4><p>La Niña conditions remained in the moderate range during December and early January, prompting NOAA to continue its <a href="https://oceanservice.noaa.gov/facts/ninonina.html" target="_blank" rel="noopener noreferrer">La Niña</a> advisory in a January 14 <a href="https://iri.columbia.edu/our-expertise/climate/forecasts/enso/current/?enso_tab=enso-cpc_update" target="_blank" rel="noopener noreferrer">monthly discussion</a> of the state of the El Niño/Southern Oscillation, or ENSO.</p><p>Over the past month, sea surface temperatures in the benchmark Niño 3.4 region of the eastern tropical Pacific (5°N-5°S, 170°W-120°W) have been approximately 1 degree Celsius below average. The threshold for "strong" La Niña conditions is 1.5 degrees Celsius below average; "moderate" La Niña conditions are 1.0-1.5 degrees below average.</p><p>Forecasters at NOAA and at Columbia University's International Research Institute for Climate and Society <a href="https://iri.columbia.edu/our-expertise/climate/forecasts/enso/current/?enso_tab=enso-cpc_plume" target="_blank" rel="noopener noreferrer">expect La Niña conditions</a> will continue through the winter (95% chance during January-February-March), and potentially transition to "neutral" during the spring (55% chance during April-May-June). About half of all La Niña events continue into a second year, but fewer than 20% of the ENSO models predicted that La Niña conditions would last into the summer of 2021.</p>
<h4>Arctic Sea Ice: Third-Lowest December Extent on Record</h4><p>Arctic sea ice extent during December 2020 was the third-lowest in the 42-year satellite record, behind 2016 and 2017, according to the <a href="http://nsidc.org/arcticseaicenews/" target="_blank" rel="noopener noreferrer">National Snow and Ice Data Center</a>. <a href="https://nsidc.org/data/seaice_index" target="_blank" rel="noopener noreferrer">Antarctic sea ice extent</a> in December 2020 was near-average.</p>
<h4>Notable Global Heat and Cold Marks for December 2020</h4><p>– Hottest temperature in the Northern Hemisphere: 41.5°C (106.7°F) at Matam, Senegal, December 2;<br>– Coldest temperature in the Northern Hemisphere: -57.5°C (-71.5°F) at Oymykon, Russia, December 29;<br>– Hottest temperature in the Southern Hemisphere: 48.7°C (119.7°F) at Birdsville, Australia, December 5; and<br>– Coldest temperature in the Southern Hemisphere: -44.9°C (-48.8°F) at Dome A, Antarctica, December 3.</p>
<h4>Major Weather Stations' New All-Time Heat or Cold Records in December 2020</h4><p>Among global stations with a record of at least 40 years, two stations set all-time cold records in December, and no stations set an all-time heat record:</p><p>Hamamasu (Japan) min. -21.5°C (-6.7°F), December 31; and<br>Bibai (Japan) min. -26.5°C (-15.7°F), December 31.<br></p><p><em>Statistics courtesy of <a href="http://www.mherrera.org/temp.htm" target="_blank" rel="noopener noreferrer">Maximiliano Herrera</a>.</em></p>

In December of 1924, the heads of all the major lightbulb manufacturers across the world met in Geneva to concoct a sinister plan. Their talks outlined limits on how long all of their lightbulbs would last. The idea is that if their bulbs failed quickly customers would have to buy more of their product. In this video, we're going to unpack this idea of purposefully creating inferior products to drive sales, a symptom of late-stage capitalism that has since been coined planned obsolescence. And as we'll see, this obsolescence can have drastic consequences on our wallets, waste streams, and even our climate.
<p>Corporations create obsolescence through two main avenues: planned obsolescence and perceived obsolescence. Both practices are meant to make a product seem useless or actually useless in order to drive sales. Planned obsolescence occurs when a company manufactures a device to fail before its realistic lifespan. This usually means a weaker filament, plastic encasement, or a fragile glass screen that limits the durability of the good. In the case of the collection of 1920s electricity companies known as the Phoebus cartel, they applied this principle to lightbulbs. The Phoebus cartel collectively cut the lifespan of their products in half from 2,000 to 1,000 hours, so that consumers would have to buy twice the amount of lightbulbs that they did previously. </p><p>On the other side of obsolescence, there's the more amorphous phenomenon of perceived obsolescence. Think of that new phone you bought or that new style of clothes you've been eyeing or even this year's new line of pickup trucks. All these are instances of perceived obsolescence. When companies release their new line of products, their older products quickly become unfashionable or less desirable. In order to get you to keep buying their goods corporations consistently market their new lines to make it seem like that new gadget you just bought a year ago is an antique, even though, in most cases, the older product still works. This kind of perceived obsolescence is especially prevalent with cars, technology, and fashion because these consumer goods have been transformed into status symbols. If you want to keep up appearances, you grab the newest model of the iPhone. If you want to look good, you buy the latest style from that Instagram ad. </p><p>But how and why do planned and perceived obsolescence work on us? Go watch the full video to find out the answer.</p><p><em><a href="https://www.youtube.com/channel/UCNXvxXpDJXp-mZu3pFMzYHQ" target="_blank">Our Changing Climate</a> is an environmental YouTube channel that explores the intersections of social, political, climatic, and food-based issues.
