What the world will look like 4°C warmer
Will your grandchildren live in cities on Antarctica?
Micronesia is gone – sunk beneath the waves. Pakistan and South India have been abandoned. And Europe is slowly turning into a desert. This is the world, 4°C warmer than it is now.
But there is also good news: Western Antarctica is no longer icy and uninhabitable. Smart cities thrive in newly green and pleasant lands. And Northern Canada, Scandinavia and Siberia produce bountiful harvests to feed the hundreds of millions of climate refugees who now call those regions home.
This map, which shows some of the effects a 4°C rise in average temperature could have on the planet, is eight years old, but it seems to get more contemporary as it ages (and the planet warms). Antarctica is white with snow and ice, on the ground and, traditionally, on most maps. This map has turned the continent's western end incongruously green. And recent reports confirm that Antarctica is indeed turning green.
Few serious scientists doubt that climate change is happening, or that it is man-made. But the fact remains that many still have a hard time grasping global warming, partly as a convenient way of ignoring the destructive impact it is predicted to have.
Those on the fact-based side of this argument should realise that continuously bombarding the opposition with doom and gloom is likely to reinforce their resistance to accepting the new paradigm.
This map offers an alternative: lots of misery and disaster, but also plenty of hope and solutions. Not solutions that will lead us back to the climate of a few decades ago – costly and pointless – but solutions that work for the world as it will be, when it will be much warmer than it is now.
First, the bad news. Brown indicates 'Uninhabitable due to floods, drought or extreme weather'. Say goodbye to the Eastern Seaboard of the U.S., to Mexico and Central America, to the middle third of South America. In Africa, Mozambique and Madagascar are gone; Asia loses much of the Indian subcontinent, including all of Pakistan; Indochina is abandoned, as is most of Indonesia. As the map mentions, “The last inhabitants of (the South-west U.S. are) migrating north. The Colorado river is a mere trickle”; “Deglaciation means (Peru) is dry and uninhabitable”; and “Bangladesh is largely abandoned, as is South India. (In) Pakistan, isolated communities remain in pockets”.
Orange is not much better: 'Uninhabitable desert'. That's most of the U.S. and the rest of South America, almost the entirety of Africa and the southern halves of Europe and Asia. “Deserts have encroached on (Southern Europe), rivers have dried up and the Alps are now snow-free. Goats and other hardy animals are kept at the fringes”, the map predicts.
Red is for lands lost to the rising tide (assuming +4°C adds two metres to ocean levels). This may not seem a lot, but this is where populations are concentrated. In the U.S. for instance, counties directly on the shoreline constitute less than 10% of the total land area (not including Alaska), but account for 40% of the total population.
But there is a flipside. Light-green stands for food-growing zones, and compact high-rise cities. That's Western Antarctica, “unrecognisable now. Densely populated with high-rise cities”. New Zealand, sparsely populated in our time, will also be transformed into a high-density population centre. There will be a lot more room for this in the northern hemisphere: Siberia and Canada, where “reliable precipitation and warmer temperatures provide ideal growing conditions for most of the world's subsistence crops.” And the UK, Scandinavia, Greenland and northern Russia, which will be dotted with compact high-rise cities to “provide shelter for much of the world's population”.
A warmer climate could even lead to reforestation in certain areas of the world, including the Sahel and Western Australia. The regions abandoned to desertification are empty, but not useless: they will be used for solar farming (green dots) and geothermal energy (red dots). Giant wind farms off the coasts of South America, Alaska and in the North Sea will generate the remainder of the planet's energy needs.
This map was first published by New Scientist, and republished by Parag Khanna for his book Connectography. Khanna speculates: “The entire population of the Arctic region today is less than 4 million. Could it be 400 million within the coming 20 years?”
Now is the time to buy property in Greenland – before it too turns green...

It's the first time scientists have discovered an animal that doesn't perform aerobic respiration.
- The animal is a tiny parasite called Henneguya salminicola.
- The parasite infects salmon and lives within the fish muscle, though scientists aren't quite sure how it breaks down nutrients for survival.
- The findings are published in the journal PNAS.
H. salminicola inside of a salmon
An evolutionary advantage<p>Losing that mitochondrial genome appears to have been a less-is-more type of advantage for the parasite.</p><p style="margin-left: 20px;">"Myxozoans have gone through outstanding morphological and genomic simplifications during their adaptation to parasitism from a free-living cnidarian ancestor," the authors wrote. "As a highly diverse group with >2,400 species, which inhabit marine, freshwater, and even terrestrial environments, evolutionary loss and simplification has clearly been a successful strategy for Myxozoa, which shows that less is more."</p><p>The researchers aren't quite sure how <em>H.</em> <em>salminicola </em>breaks down nutrients without oxygen. One possibility is that it absorbs molecules from its host. It's hard to tell, however, because the researchers analyzed dead parasites — they'd need to look at parasites living within the fish to get a better understanding of how the creatures operate.</p><p>The discovery highlights how much scientists still have to learn about the diversity of life on Earth. Atkinson told <a href="https://www.cnn.com/2020/02/26/world/first-animal-doesnt-breathe-oxygen-scn-trnd/index.html" target="_blank"><em>CNN</em></a> that he expects <em>H.</em> <em>salminicola </em>isn't the only animal that can survive without oxygen, or in even "weirder modes of existence." </p>
The search for alien life<p>One interesting implication of the discovery is what it means for the search for alien life. It's long been thought that, if aliens exist, they'd likely breathe oxygen. After all, it's the best element that we know of for producing large amounts of energy for metabolism, allowing us to "grow large, run and jump and think," as David Catling, a planetary scientist at the University of Washington, told <a href="https://www.forbes.com/sites/brucedorminey/2012/11/20/why-e-t-would-also-breathe-oxygen/#48fdfed63c55" target="_blank"><em>Forbes</em></a>. <br></p><p style="margin-left: 20px;">"Because of oxygen's chemical advantages and the history of complex life on earth is so intertwined with oxygen levels," he said. "I think E.T. would also breathe oxygen."</p><p>This is one reason why many think Earth-like exoplanets with atmospheres that likely contain oxygen would be good candidates for harboring alien life. But, in a small way, the newly discovered parasite gives reason to think that the search for alien life — and their life-supporting planets — might be far more complicated.</p>
Archaeology clues us in on the dangers of letting viruses hang around.
- A University of Otago researcher investigates the spread of disease in ancient Vietnam.
- The infectious disease, yaws, has been with us for thousands of years with no known cure.
- Using archaeology to investigate disease offers clues into modern-day pandemics.
History-Changing Archaeological Finds<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="ed6ad05071e93f257aa0b73f4001c805"><iframe type="lazy-iframe" data-runner-src="https://www.youtube.com/embed/gydYHHfnLhE?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span><p>While we rightfully look toward infectious disease experts during times such as now, archaeologists also have plenty to offer. A <a href="http://journals.upress.ufl.edu/bioarchaeology/article/view/1173" target="_blank">new research article</a>, published in the journal, Bioarchaeology Journal, turns back the clock to ancient Vietnam. The findings offer important clues about why we need to eradicate COVID-19.</p><p>Lead author Melandri Vlok, a PhD student at the University of Otago in New Zealand (with support from researchers in Australia, Vietnam, Japan, and the UK), investigated a case of yaws that ran through the Neolithic archeological site of Mán Bạc in Northeast Vietnam. </p><p>Yaws remains a common infectious disease in at least 13 tropical countries, with up to a half-million infected each year. Hard skin lesions form on the victim's bodies; they can form painful ulcers. While lesions usually subside within six months, bone and joint pain and fatigue are common. Some cases last many years and result in permanent scars. On occasion, death follows a long battle. </p><p>Subsistence farmers in mainland China have long battled the environment. Finding the right soil and water sources for their crops has been a generational battle. Roughly 4,000 years ago, such farmers made their way into Mainland Southeast China (modern day Vietnam), where, as Vlok writes, "genetic admixture and social transition occurs between foragers and farmers." In 2018, Vlok traveled to Mán Bạc to study the remains of seven skeletons, which included two adults, two adolescents, and two children.</p><p>Her findings help give us perspective on today's proliferation of the coronavirus. As she <a href="https://www.otago.ac.nz/news/news/releases/otago744185.html" target="_blank">says</a>, </p><p style="margin-left: 20px;">"This matters, because knowing more about this disease and its evolution, it changes how we understand the relationship people have with it. It helps us understand why it's so difficult to eradicate. If it's been with us thousands of years it has probably developed to fit very well with humans." </p>

The goal of the research was to identify disease spread through cultures and the chronic problems left behind, sometimes for millennia. Vlok notes how temperature fluctuations in the Mán Bạc region affected a variety of diseases. Yaws appeared to have spread easily due to an abundance of water and vegetation, combined with increased population density—children are more likely to spread this disease.</p><p style="margin-left: 20px;">"Pre-industrialized agricultural communities have also been associated with increased incidence of yaws. The coastal region is also slightly warmer and more humid than inland northern Vietnam and therefore more conducive to the spread of yaws."</p><p>The Climate Clock is <a href="https://www.washingtonpost.com/climate-environment/2020/09/21/climate-change-metronome-clock-nyc/" target="_blank">ticking down</a>. We're already experiencing the ravages of this global shift, and it's not going to get any easier if interventions are not immediately legislated. While no single science will help us wrap our heads around the immediate future, Vlok suggests factoring in archaeology. Past precedent matters.</p><p>Gazing back a few hundred generations offers important clues for the future—really, the present—that we must confront. A concerted effort by the World Health Organization in the 1950s couldn't eradicate yaws. Diseases that have an opportunity to hang around will exploit every advantage it can. The blasé attitude too many Americans currently hold about the novel coronavirus's dangers is going to have a reverberating effect through the generations. As Vlok concludes, </p><p style="margin-left: 20px;">"This shows us what happens when we don't take action with these diseases. It's a lesson of what infectious diseases can do to a population if you let them spread widely. It highlights the need to intervene, because sometimes these diseases are so good at adapting to us, at spreading between us."</p><p>--</p><p><em>Stay in touch with Derek on <a href="http://www.twitter.com/derekberes" target="_blank">Twitter</a>, <a href="https://www.facebook.com/DerekBeresdotcom" target="_blank" rel="noopener noreferrer">Facebook</a> and <a href="https://derekberes.substack.com/" target="_blank" rel="noopener noreferrer">Substack</a>.

Are you mentally exhausted? Here's how to tell (and what to do about it).
- Mental exhaustion is a symptom of long-term stress. It can affect physical well-being, causing a person to feel physically exhausted.
- There are some things you can do yourself to alleviate your mental strain, which will then eliminate some of the mental exhaustion you're feeling.
- Seeking medical assistance for mental exhaustion is common, with therapists working alongside patients to help develop healthy coping mechanisms and doctors assisting with treatments such as antidepressants or anti-anxiety medications where needed.

Knowing the symptoms of mental exhaustion can help you understand when to seek help.
Credit: Vectorium on Shutterstock<p>According to <a href="https://www.medicalnewstoday.com/articles/mentally-exhausted#symptoms" target="_blank">Medical News Today</a>, mental exhaustion can affect physical well-being, causing a person to feel physically exhausted.</p><p><strong>What are the symptoms of mental exhaustion? </strong></p><ul><li>Low emotional resilience</li><li>Feeling stressed or anxious</li><li>Cynicism or pessimism, feeling like nothing is going right</li><li>Apathy (a feeling of not caring)</li><li>Difficulty concentrating</li><li>Feelings of helplessness</li><li>Physical exhaustion or fatigue</li><li>Sleep problems (sleeping too much or too little)</li><li>Feelings of being overwhelmed</li><li>Low motivation</li><li>Feeling distracted or on edge</li><li>Difficulty with memory</li><li>Headaches</li><li>Drastic weight gain/loss</li><li>Changes in appetite</li><li>Depression/depressive symptoms</li><li>Suicidal ideation </li><li>Irritability </li></ul><p><strong>What is the difference between stress and mental exhaustion? </strong></p><p>Stress is something we all experience - it's the body's natural response to situations that are new, scary, worrisome, etc. The biological response is a surge of stress hormones (adrenaline and cortisol) that helps us react quickly to perceived threats or high-pressure situations. With stress, once the "threat" has been removed, your body will stop the surge of hormones and you should go back to your normal state. </p><p>Mental exhaustion, however, is a symptom of long-term stress. When you are continually dealing with things that activate your body's natural stress response, your cortisol and adrenaline levels remain high. Eventually, this begins to interfere with your body's normal functions (such as digestions, sleep, your immune system, etc.). </p><p><strong>What causes mental exhaustion? </strong></p><p>Mental exhaustion or "burn out" are terms that are often used to explain the feeling of being overworked or generally stressed about things relating to your work, but mental exhaustion can be caused by a long period of persistent stress in any areas of your life. It could be work, it could be your home life, or it could be a combination. </p><p>Mental exhaustion can be caused by high-pressure jobs, working long hours, being dissatisfied at work, being the caregiver for an ill loved one, living with a chronic illness, the sudden death of a loved one, poor work-life balance, lack of social support, or a number of other factors. </p><p><strong>How can I tell if I'm emotionally exhausted?</strong></p><p><a href="https://www.psychologytoday.com/intl/blog/the-chronicles-infertility/201905/8-questions-check-if-youre-emotionally-exhausted" target="_blank" rel="noopener noreferrer">Psychology Today</a> has an incredibly helpful "emotional exhaustion inventory" to check your status: </p><ol><li>I smile less frequently than I used to, even in situations I typically would find funny.</li><li>My senses seem dulled, so food tastes flat, music doesn't move me, back rubs give me no pleasure/release, and I reach for black or grey clothes.</li><li>I can't sleep. Either I can't fall asleep, stay asleep, or all I want to do is sleep. </li><li>Socializing is difficult. When I am with friends or family, I feel disconnected and have a hard time paying attention to what they say.</li><li>I get startled easily by voices, noises or movement. I feel jumpy and jittery. </li><li>I am more irritable than I used to be, especially in lines, online and on the phone. </li><li>My anxiety level is higher than usual, and crowds and traffic make me feel claustrophobic. </li><li>I cry more easily, particularly during movies, sad news reports, sentimental stories and even shows with happy endings.</li></ol><p>If any of these statements sound familiar, you could be dealing with mental/emotional exhaustion.</p>

There are some things you can do yourself to alleviate your mental strain and thus eliminate some of the mental exhaustion you're feeling.</p><p><strong>Remove the stressors in your life. </strong></p><p>If you're overwhelmed with your tasks at work, consider asking for help or delegating some of your tasks to others, if possible. If you're feeling overwhelmed at home, consider enlisting the help of a babysitter or house cleaner to eliminate some of your stress. </p><p><strong>Keep a journal. </strong></p><p>Writing can be extremely therapeutic. Writing about things you are thankful for (especially at a time in your life where you are overwhelmed) can positively impact your mental health way more than you realize. <a href="https://www.psychologytoday.com/intl/blog/the-chronicles-infertility/201905/8-questions-check-if-youre-emotionally-exhausted" target="_blank" rel="noopener noreferrer">Research</a> has showed that people who practice gratitude (and gratitude expression exercises) often have a higher sense of well-being, fewer symptoms of physical illness, reduced stress, and higher relationship satisfaction.</p><p><strong>Exercise regularly.</strong></p><p>While you may not have time to visit the gym, there are many ways you can incorporate a bit of exercise into your daily activities, such as taking the stairs more often than the elevator at work, waking up early to go for a walk/run or even doing some physical activity while watching television at the end of the day. </p><p><a href="https://www.sciencedirect.com/science/article/pii/S1469029210000117" target="_blank" rel="noopener noreferrer">A 2010 study</a> of 533 Swiss police officers and emergency service corps found that exercise was associated with enhanced health and actually protected against stress-related health problems.

If you're not into meditation, other forms of relaxation including yoga, deep breathing exercises, massage, aromatherapy, or tai chi may also be helpful. </p><p><strong>Adjust your sleeping patterns. </strong></p><p>Sleep is essential for your emotional well-being. <a href="https://www.healthline.com/health/mental-exhaustion#treatment-and-coping" target="_blank" rel="noopener noreferrer">HealthLine</a> suggests developing a bedtime routine and sticking to it. It can also be particularly helpful if this routine occurs at roughly the same time every evening. This can be doing some light reading for a few minutes before bed at the same time every night, for example. </p><p><strong>Seek medical assistance from a doctor and/or therapist. </strong></p><p>Mental exhaustion is an incredibly real and difficult thing to cope with, and seeking medical treatment for it could be one of the best choices you make. A therapist, for example, can provide you with the tools you need to cope with daily stressors. A doctor can talk to you about your symptoms and potentially prescribe medicines (such as antidepressants or anti-anxiety medications) if they feel it may be helpful. </p>
