Mangroves play a vital role in capturing carbon from the atmosphere. Mangrove forests are tremendous assets in the fight to stem the climate crisis. They store more carbon than a rainforest of the same size.
<p>However, they are under threat from <a href="http://www.ecowatch.com/tag/sea-level-rise" target="_self">sea level rise</a>. A <a href="https://science.sciencemag.org/cgi/doi/10.1126/science.aba2656" target="_blank">new study</a> found that if emissions continue unabated, mangroves will not be able to keep up and could disappear in 30 years, as <a href="https://www.theverge.com/2020/6/4/21280580/sea-level-rise-mangroves-climate-change-2050" target="_blank">The Verge</a> reported.</p><p>The new study published in the journal <em><a href="https://science.sciencemag.org/cgi/doi/10.1126/science.aba2656" target="_blank">Science</a></em> found that mangroves will start to die out if sea levels rise just six millimeters per year. However, mangroves are more likely to survive when sea level rise is less than 5 millimeters (about 0.2 inches) per year, which is projected for low-emissions scenarios this century, according to a Rutgers University <a href="https://www.sciencedaily.com/releases/2020/06/200604152109.htm" target="_blank">statement</a>.</p>
<p>"Under high-emissions scenarios, rates of sea-level rise on many tropical coastlines will exceed 7 millimeters per year, the rate at which we concluded there's a 6.2 percent probability mangroves can sustain growth," said co-author Erica Ashe, a post-doctoral scientist in the Department of Earth and Planetary Sciences at Rutgers University, in the <a href="https://www.sciencedaily.com/releases/2020/06/200604152109.htm" target="_blank">statement</a>. "The loss of these mangrove ecosystems could result in increased carbon dioxide in the atmosphere and fewer vital buffers against storm surges in the long run."</p><p>Around the world, there are 80 different species of mangrove trees. All of them grow in warm, shallow, coastal waters around the tropics. They spread their roots in sediment that is under the water, while their upper trunks, branches and leaves are above the water. The forests usually flood twice a day during high tide, according to <a href="https://www.newsweek.com/mangrove-forests-expected-sea-level-rise-2050-greenhouse-gas-emissions-1508466" target="_blank">Newsweek</a>.</p><p>They play a crucial role in stabilizing the coastline, providing protection from storms, waves, and tidal erosion. Their root systems provide a habitat for fish and other animals, according to <a href="https://www.newsweek.com/mangrove-forests-expected-sea-level-rise-2050-greenhouse-gas-emissions-1508466" target="_blank">Newsweek</a>. Mangrove forests work their magic by pulling freshwater from salty seawater to serve as a nursery for fish, crustaceans and shellfish. But if their roots are completely submerged for too long, the mangroves will drown.</p>
<p>As <a href="https://www.theverge.com/2020/6/4/21280580/sea-level-rise-mangroves-climate-change-2050" target="_blank">The Verge</a> noted, mangrove forests are a boon to people and the planet, which is why scientists in Florida have sought to use mangroves as a defense for coastal communities from the ravages of the climate crisis. However, for mangroves to help us, we will first need to help them.</p><p>"We have an opportunity here to take action and to keep the rates of sea level rise below these critical thresholds, which is part of the reason that this is an important study," says Ashe, as <a href="https://www.theverge.com/2020/6/4/21280580/sea-level-rise-mangroves-climate-change-2050" target="_blank">The Verge</a> reported.</p><p>To figure out just how much sea level rise was too much for the mangroves, Ashe and her colleagues, led by Neil Saintilan from Macquarie University in Australia, examined sediment core samples from 78 locations around the world. Those samples shed light on how mangroves responded to past changes in the rate of sea level rise, which went from more than 10 millimeters (0.39 inches) per year nearly 10,000 years ago to almost stable around 4,000 years later, as <a href="https://www.newsweek.com/mangrove-forests-expected-sea-level-rise-2050-greenhouse-gas-emissions-1508466" target="_blank">Newsweek</a> reported. They discovered that mangrove ecosystems only developed when rates of sea level rise dropped below about 7 millimeters a year.</p>
<p>"There was good news and bad news. The good news was that mangroves were clearly capable of surviving much higher rates of sea-level rise than we have around the world at present," Saintilan told <a href="https://www.newsweek.com/mangrove-forests-expected-sea-level-rise-2050-greenhouse-gas-emissions-1508466" target="_blank">Newsweek</a>. "There were many examples where mangroves were able to keep pace with sea-level rise of 5 millimeters per year; the current rate is just over 3 millimeters per year."</p><p>"However, there was little evidence that mangroves could keep pace with sea-level rise of over 7 millimeters per year, and this threshold was lower for mangroves on coral reef settings, which failed to keep pace with sea-level rise above 5 millimeters per year. If the rate of sea-level rise doubles, mangroves are in serious trouble," he added.</p>

By Jacob L. Steenwyk and Antonis Rokas
From the mythical minotaur to the mule, creatures created from merging two or more distinct organisms – hybrids – have played defining roles in human history and culture. However, not all hybrids are as fantastic as the minotaur or as dependable as the mule; in fact, some of them cause human diseases.
<p>We are evolutionary biologists who are trying to understand <a href="https://doi.org/10.1371/journal.ppat.1008315" target="_blank">why certain fungi infect</a> hundreds of thousands of patients each year while others are harmless. We are particularly interested in infections caused by <a href="https://doi.org/10.1016/j.cub.2013.01.021" target="_blank"><em>Aspergillus</em> fungi</a>, a group of molds – multicellular fungi that typically grow by forming networks of hairlike filaments – that can <a href="https://doi.org/10.1128/CMR.00140-18" target="_blank">cause very serious infections in patients with weak immune systems</a>. While examining <em>Aspergillus</em> strains isolated from patients with lung-related diseases, we unexpectedly discovered <a href="https://doi.org/10.1016/j.cub.2020.04.071" target="_blank">an <em>Aspergillus</em> hybrid</a> that infects humans. This finding is significant not only because this is the first known example of a hybrid mold infecting humans but also because accurate identification of the species causing disease is key for managing fungal infections.</p>
When Looking Through a Microscope Isn’t Close Enough.
<p>For the last few years, <a href="http://www.rokaslab.org/" target="_blank">our team at Vanderbilt University</a>, <a href="https://www.researchgate.net/lab/Gustavo-Goldman-Lab" target="_blank">Gustavo Goldman's team at São Paulo University in Brazil</a> and many other collaborators around the world have been collecting samples of fungi from patients infected with different species of <em>Aspergillus</em> molds. One of the species we are particularly interested in is <a href="https://doi.org/10.1006/rwgn.2001.0082" target="_blank"><em>Aspergillus nidulans</em>, a relatively common and generally harmless fungus</a>. Clinical laboratories typically identify the species of <em>Aspergillus</em> causing the infection by examining cultures of the fungi under the microscope. The problem with this approach is that very closely related species of <em>Aspergillus</em> tend to look very similar in their broad morphology or physical appearance when viewing them through a microscope.</p><p>Interested in examining the varying abilities of different <em>A. nidulans</em> strains to cause disease, we decided to analyze their total genetic content, or genomes. What we saw came as a total surprise. We had not collected <em>A. nidulans</em> but <em>Aspergillus latus</em>, a close relative of <em>A. nidulans</em> and, as we were to soon find out, <a href="https://doi.org/10.1016/j.cub.2020.04.071" target="_blank">a hybrid species that evolved through the fusion of the genomes</a> of two other <em>Aspergillus</em> species: <em>Aspergillus spinulosporus</em> and an unknown close relative of <em>Aspergillus quadrilineatus</em>. Thus, we realized not only that these patients harbored infections from an entirely different species than we thought they were, but also that this species was the first ever <em>Aspergillus</em> hybrid known to cause human infections.</p>Several Different Fungal Hybrids Cause Human Disease.
<p>Hybrid fungi that can cause infections in humans are well known to occur in several different lineages of single-celled fungi known as yeasts. Notable examples include multiple different species of <a href="https://doi.org/10.1002/yea.3242" target="_blank">yeast hybrids</a> that cause the human diseases <a href="https://rarediseases.info.nih.gov/diseases/6218/cryptococcosis" target="_blank">cryptococcosis</a> and <a href="https://www.cdc.gov/fungal/diseases/candidiasis/index.html" target="_blank">candidiasis</a>. Although pathogenic yeast hybrids are well known, our discovery that the <em>A. latus</em> pathogen is a hybrid is a first for molds that cause disease in humans.</p><img lazy-loadable="true" src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMzM3NDk4Mi9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYyMTIwOTgyOX0.gCsk3b5GHdZq78oT3M2ajq3QYT9i-PrLNjoxB6AF1Dg/img.jpg?width=980" id="365cb" class="rm-shortcode" data-rm-shortcode-id="e1f11ec0f5a0b5a5bc3a94b1fa86bd97" data-rm-shortcode-name="rebelmouse-image" />
(Left) Candida yeasts live on parts of the human body. Imbalance of microbes on the body can allow these yeasts, some of which are hybrids, to grow and cause infection.

<p><a href="https://doi.org/10.1371/journal.ppat.1008315" target="_blank">Why certain <em>Aspergillus</em> species are so deadly</a> while others are harmless remains unknown. This may in part be because <a href="https://doi.org/10.1016/j.fbr.2007.02.007" target="_blank">combinations of traits, rather than individual traits</a>, underlie organisms' ability to cause disease. So why then are hybrids frequently associated with human disease? Hybrids inherit genetic material from both parents, which may result in new combinations of traits. This may make them more similar to one parent in some of their characteristics, reflect both parents in others or may differ from both in the rest. It is precisely this mix and match of traits that hybrids have inherited from their parental species that <a href="https://www.nytimes.com/2010/09/14/science/14creatures.html" target="_blank">facilitates their evolutionary success</a>, including their ability to cause disease.</p>The Evolutionary Origin of an Aspergillus Hybrid.
<p>Multiple evolutionary paths can lead to the emergence of hybrids. One path is through mating, just as the horse and donkey mate to create a mule. Another path is through the merging or fusion of genetic material from cells of different species.</p><p>It is this second path that appears to have been taken by our fungus. <em>A. latus</em> appears to have two of almost everything compared to its parental species: twice the genome size, twice the total number of genes and so on. But unlike other hybrids, which are often sterile like the mule, we found that <em>A. latus</em> is capable of reproducing both asexually and sexually.</p><p>But how distinct were the parents of <em>A. latus</em>? By comparing the parts contributed by each parent in the <em>A. latus</em> genome, we estimate that its parents are approximately 93% genetically similar, which is about as related as we humans are with lemurs. In other words, <em>A. latus</em>, an agent of infectious disease, is the fungal equivalent of a human-lemur hybrid.</p>How A. Latus Differs From its Parents.
<p>Elucidating the identity of closely related fungal pathogens and how they differ from each other in infection-relevant characteristics is a key step toward reducing the burden of fungal disease. For example, we found that <em>A. latus</em> was three times more resistant than <em>A. nidulans</em>, the species it was originally identified as using microscopy-based methods, to one of the most common antifungal drugs, <a href="https://www.drugbank.ca/drugs/DB00520" target="_blank">caspofungin</a>. This result provides a clear example of the potential importance of accurate identification of the <em>Aspergillus</em> pathogen causing an infection.</p><p>We also examined how <em>A. latus</em> and <em>A. nidulans</em> interact with cells from our immune system. We found that immune cells were less efficient at combating <em>A. latus</em> compared to <em>A. nidulans</em>, suggesting the hybrid fungus may be trickier for our immune systems to identify and destroy.</p><p>In the midst of the COVID-19 pandemic, our quest to understand <em>Aspergillus</em> pathogens is becoming more urgent. Growing evidence suggests that <a href="https://doi.org/10.1111/myc.13096" target="_blank">a fraction of COVID-19 patients are also infected with <em>Aspergillus</em>.</a> More worrying is that these <a href="https://doi.org/10.3201/eid2607.201603" target="_blank">secondary <em>Aspergillus</em> infections</a> can worsen the clinical outcomes for those infected with the novel coronavirus. That being said, we stress that little is known about <em>Aspergillus</em> infections in COVID-19 patients due to a lack of systematic testing, and none of the infections identified so far appear to have been caused by hybrids.</p><p>So, when it comes to hybrids, some are fantastic (the minotaur), some are helpful (the mule) and some are dangerous (<em>Aspergillus latus</em>). Understanding more about the biology of <em>Aspergillus latus</em> may help in our understanding of how microbial pathogens arise and how to best prevent and combat their infections.</p>

Experts are worried that COVID-19, a primarily respiratory and airway disease, could have permanent effects on lungs, inhibiting the ability for divers to continue diving. Tiffany Duong / Ocean Rebels
Scuba divers around the world are holding their metaphorical breath to see if a coronavirus infection affects the ability to dive.
<p>Some preliminary data, while inconclusive, indicates that permanent lung damage can occur even in mild cases. All experts are advocating for further studies to examine potential permanent effects.</p><p>"Like other respiratory illnesses, COVID-19 can cause lasting lung damage," said Dr. Matias Nochetto, director of medical service at Divers Alert Network (DAN). The doctor addressed the fears of many scuba divers in a <a href="https://www.facebook.com/DiversAlertNetwork/videos/691682591631410" target="_blank">company webinar</a> on diving after a COVID-19 infection.</p>
<p>Joseph Dituri, the principal investigator in a study to use hyperbaric medicine to treat coronavirus patients, explained to EcoWatch that lung cells are damaged by both the coronavirus infection and the body's inflammatory reaction to it, reducing lung function and gas exchange capabilities. Nochetto noted in the <a href="https://www.facebook.com/DiversAlertNetwork/videos/691682591631410" target="_blank">webinar</a> that the inflammation causes leakage of fluid and pus into the lungs that can result in irreparable <a href="https://www.dw.com/en/covid-19-recovered-patients-have-partially-reduced-lung-function/a-52859671" target="_blank">lung scarring and damage</a>.</p><p>"This is not good for anyone's lungs, let alone diving," the doctor added. "There is no proof that any lungs have fully recovered from COVID-19. Everyone that has had COVID so far, even if they had COVID in January, their lungs are likely still recovering, so it is too soon to say if they are or are not gonna be able to dive."</p>
<img lazy-loadable="true" src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMzM3NDA3MC9vcmlnaW4ucG5nIiwiZXhwaXJlc19hdCI6MTYwMjcxOTg2Mn0.zzMhWKDnhrVtj9HFXefdjLWW1bKKO9Kh3AZCLu-J3kA/img.png?width=980" id="49f9e" class="rm-shortcode" data-rm-shortcode-id="c47b0ecdd76153f9ce088ef76fba00eb" data-rm-shortcode-name="rebelmouse-image" />

<p>An April 15 report from Austria put the dive world on high alert. Dr. Frank Hartig treated six infected divers who only suffered mild symptoms, were not hospitalized and recovered at home, reported <a href="https://www.caymancompass.com/2020/04/24/divers-face-long-term-health-impact-from-covid-19/?fbclid=IwAR1RQXV50frrwU3YnG8Qh12oMQ0m1l9iJ61eanApvk7_twmqduOsKwNgbEs" target="_blank">Cayman Compass</a>.</p><p>Although "clinically recovered," all six patients exhibited "irreversible" long-term lung damage which made a full recovery "unlikely," Hartig said. Two exhibited asthmatic-like, irritated lungs, two suffered low oxygen supplies, and four showed "significant changes" to lung structure, reported <a href="https://www.caymancompass.com/2020/04/24/divers-face-long-term-health-impact-from-covid-19/?fbclid=IwAR1RQXV50frrwU3YnG8Qh12oMQ0m1l9iJ61eanApvk7_twmqduOsKwNgbEs" target="_blank">Cayman Compass</a>.</p><p>"None of the six divers can be released for diving for the time being, despite their well-being," Hartig said, reported <a href="http://divemagazine.co.uk/skills/8907-serious-problems-diving-after-covid19" target="_blank">Dive Magazine</a>.</p>
<p>The doctor said that patients who felt fully recovered could still suffer lung damage which could permanently prohibit scuba diving and other forms of exercise. He implored dive professionals like dive instructors and commercial divers to avoid contracting the disease at all costs.</p><p>In a <a href="https://www.uhms.org/images/Position-Statements/Return_to_Diving_Post_COVID-19_Final_NB_4-27-2020.pdf" target="_blank">responsive position statement</a>, the <a href="https://www.uhms.org/" target="_blank">Undersea Hyperbaric Medical Society (UHMS)</a> called the findings "generalized" and "premature." The medical society emphasized, "At the present time, we simply do not have sufficient data to support or refute the definitive proclamations made by this case series." UHMS, the primary source of scientific information regarding diving, noted that more time and studies are needed to accurately access the potential impact of the disease on individuals' health and ability to dive.</p><p>UHMS also highlighted that COVID-19 shares many features with other serious viral pneumonia, including requiring a "weeks or months" period of convalescence before returning to full activities, including diving.</p>
<p>In their <a href="https://www.facebook.com/DiversAlertNetwork/videos/691682591631410" target="_blank">webinar</a>, DAN's doctors similarly did not set a specific timeline for a return to diving after infection, instead advocating for individual medical assessments and fitness tests by doctors trained in dive medicine to uncover potential residual issues. Chief Medical Officer Dr. Jim Chimiak emphasized the need to evaluate any residual damage to lung structure and function due to coronavirus before considering diving again.</p><p>"It's never bad to be conservative especially as you return to diving after a long delay," he said. "It's not automatically sating you can no longer dive, but it needs to be assessed on a case by case basis."</p><p>Dr. Douglas Ebersole, a cardiology consultant for DAN, avid tech diver and recovering COVID-19 patient, agreed that there was no "one size fits all" answer to when divers who have been infected with coronavirus can safely return to the sport, reported <a href="https://www.divetech.com/post/diving-in-the-era-of-covid-19" target="_blank">Dive Tech</a>.</p><p>Ebersole agreed with UHMS and DAN that it was too early to conclude whether infections could lead to permanent, sidelining injuries, but compared the coronavirus to its close viral cousin, severe acute respiratory syndrome (SARS). A 2004 study found that half of "recovered" SARS patients exhibited pulmonary function defects three months after hospital discharge, but that impairment was "mild" in most cases, Ebersole wrote.</p>
<p>The <a href="http://www.sbmhs-bvoog.be/2020%200412%20Position%20of%20the%20BVOOG.pdf" target="_blank">Belgian Society for Diving and Hyperbaric Medicine</a> said in a statement, "A person who has had COVID-19 infection with severe pulmonary symptoms may suffer from prolonged or even permanent pulmonary damage, even if the lung function seems to have returned to (near) normal," putting them at higher risk for lung barotrauma injuries.</p><p>The society recommending that infected, symptomatic divers wait two to three months after recovery and undergo complete pulmonary function testing, CT lung scanning, cardiac evaluations and exercise tests before attempting to dive again.</p><p>"There's no one fully recovered," Chimiak concluded. "Stay tuned. It's a new disease. I think this story is not over; the book has not been written."</p>

President Trump's claim that the U.S. has the cleanest air and water in the world has been widely refuted by statistics showing harmful levels of pollution. Now, a new biannual ranking released by researchers at Yale and Columbia finds that the U.S. is nowhere near the top in environmental performance, according to The Guardian.
<p>Not only is the U.S. not in the top 10, it's not in the top 20. It ranks 24th in the 2020 <a href="https://epi.yale.edu/2020-epi" target="_blank">Environmental Performance Index</a> (EPI), which was released on Thursday. The top ranked country, Denmark, has made commitments to a carbon-free future, renewable energy and sustainable agriculture. By contrast, the U.S., during the Trump administration, has worked at breakneck speed to rollback environmental regulations, expand <a href="https://www.ecowatch.com/tag/fossil-fuels" target="_self">fossil fuel</a> development, and ditch international treaties protecting the environment. He has even questioned climate science and ridiculed its findings.</p><p>"If you look at Denmark, they're doing great but they're a tiny fraction of overall carbon emissions or greenhouse gas emissions broadly," said Zach Wenderling, lead researcher on the index, as <a href="https://www.theguardian.com/environment/2020/jun/04/us-ranks-24th-in-the-world-on-environmental-performance" target="_blank">The Guardian</a> reported. "The U.S. is one of the top five players in every greenhouse gas, so we need to do better than just OK if we're going to generate the best practices."</p>
<p>Many signatories to the <a href="https://www.ecowatch.com/tag/paris-agreement">Paris agreement</a> have ramped up their commitments to have net-zero carbon emissions by 2050, especially in Europe. European countries performed the best in the new index. After Denmark, Luxembourg, Switzerland, and the United Kingdom rounded out the top four, according to <a href="https://www.theguardian.com/environment/2020/jun/04/us-ranks-24th-in-the-world-on-environmental-performance" target="_blank">The Guardian</a>.</p><p>Researchers at Yale and Columbia universities produce the global report, which is released every two years. It ranks 180 of the world's nations on 24 key indicators in 10 categories related to environmental health and ecosystem vitality.</p><p>The data-driven and empirical approach to environmental protection makes it easier to spot problems, track trends, highlight policy successes and failures, identify best practices, and optimize the benefits of investing in environmental protection, said Daniel Esty, a professor of environmental law and policy at Yale, in a university <a href="https://environment.yale.edu/news/article/dan-esty-on-the-2020-environmental-performance-index" target="_blank">press release</a>.</p><p>"[T]he EPI provides a clear and compelling way to see which countries are leading issue by issue, who is lagging, and what the best policy practices look like across a range of critical environmental challenges," said Esty, in the university <a href="https://environment.yale.edu/news/article/dan-esty-on-the-2020-environmental-performance-index" target="_blank">press release</a>.</p>
<p>Since the EPI was created in the year 2000, the U.S has never reached the top of the rankings.</p><p>"Countries that make an effort do better than those that don't don't and the U.S. right now is not making an effort. That shows up in a stagnation in the rankings where others are really seeing some significant improvements," said Esty, as <a href="https://www.theguardian.com/environment/2020/jun/04/us-ranks-24th-in-the-world-on-environmental-performance" target="_blank">The Guardian</a> reported.</p><p>The U.S., which is the second largest contributor of greenhouse gas emissions after China, is near the bottom of the rankings for advanced industrial countries. China, which suffers from poor air quality, has made significant investments in solar energy and reducing its dependence on coal, and climbed the rankings to 120th place. China is still a big polluter but has made "much more dramatic progress than other countries," Esty said, as <a href="https://www.theguardian.com/environment/2020/jun/04/us-ranks-24th-in-the-world-on-environmental-performance" target="_blank">The Guardian</a> reported.</p><p>China's ranking as the world's worst contributor to the <a href="https://www.ecowatch.com/tag/climate-crisis">climate crisis</a> is only recent. Over time, the U.S. has put more heat trapping gases into the air than any other country. India, which also sees its cities choking under polluted air quality, ranked 168th.</p>

Human activity has pushed atmospheric carbon dioxide to higher levels today than they have been at any other point in the last 23-million-years, potentially posing unprecedented disruptions in ecosystems across the planet, new research suggests.
<p>Understanding atmospheric concentrations of CO2 is "vital for understanding Earth's climate system" because it "imparts a controlling effect on global temperatures," said scientists in a study published in <a href="https://pubs.geoscienceworld.org/gsa/geology/article/doi/10.1130/G47681.1/586769/A-23-m-y-record-of-low-atmospheric-CO2" target="_blank"><em>Geology</em></a>.</p><p>Climate change is largely driven by a disproportionate increase of CO2 in the atmosphere largely resulting from the burning of fossil fuels like coal, oil and gas as well as cutting down or burning forests that serve as carbon stores, according to the <a href="https://www.ucsusa.org/resources/why-does-co2-get-more-attention-other-gases" target="_blank">Union of Concerned Scientists</a>. A 2013 study published by the <a href="https://www.ipcc.ch/report/ar5/syr/" target="_blank">Intergovernmental Panel on Climate Change</a> found that climate change from CO2 and greenhouse gas emission is not only caused by humans but has had "widespread impacts on human and natural systems."</p>
<p>Previous measurements have turned to ice cores to determine CO2 levels present in the atmosphere throughout Earth's history, but have only pieced together the last 800,000 years. To expand upon this record, researchers at the University of Louisiana at Lafayette used fossilized remains of ancient plant tissue to produce a record of atmospheric CO2 dating back 31 million years of "uninterrupted Earth history."</p><p>As plants grow, the amount of two stable carbon isotopes, carbon-12 and carbon-13, change in response to CO2 levels in the atmosphere. With this in mind, the research team measured the relative amount of these carbon isotopes in fossil plant materials from 700 measurements, published in 12 studies, characterizing ancient plants and their lipids in order to calculate concentrations of CO2 in the atmosphere during the timeframe that the plants grew.</p>
<p>This atmospheric "timeline" did not show fluctuations in CO2 that are comparable to increases seen in the last century. In fact, the highest concentrations of CO2 were found during the Miocene, between 5 and 23 million years ago, but were still determined to have been below present-day levels.</p><p>"These data suggest present-day CO2 exceeds the highest levels that Earth experienced at least since the Miocene, further highlighting the present-day disruption of long-established CO2 trends within Earth's atmosphere," write the study authors in <em>Geology</em>.</p>
<p>The abrupt increase of greenhouse gas distribution today is unprecedented in Earth's 23-million-year history, indicating that ecosystems and global temperatures may be more sensitive to smaller changes in CO2 levels than previously thought. Though CO2 levels have varied widely throughout Earth's history, researchers believe that they have never fluctuated nor been as high as in recent years.</p><p>"One of the most pressing messages that climate scientists attempt to convey to the public is that current CO2 is elevated compared to the geological past," write the study authors, adding that the results also indirectly imply that major changes in plant and early humans were not driven by large changes in CO2 but rather "relatively small-amplitude changes."</p>
<p>Humans have increased atmospheric CO2 concentration by more than one-third since the Industrial Revolution began, according to <a href="https://climate.nasa.gov/causes/" target="_blank">NASA</a>. Though the <a href="https://www.bbc.com/news/science-environment-51281986" target="_blank">BBC</a> reports "worst-case scenario" for emissions of CO2 in the 21st century is considered unlikely by researchers, scientists still expect a rise of around 3 degrees Celsius by 2100, according to <a href="https://www.theguardian.com/environment/2020/feb/15/worst-case-scenario-2050-climate-crisis-future-we-choose-christiana-figueres-tom-rivett-carnac" target="_blank">The Guardian</a> — 1.5 degrees Celsius above goals set forth by the <a href="https://ec.europa.eu/clima/policies/international/negotiations/paris_en" target="_blank">Paris agreement</a>. A report published by the <a href="https://www.climate.gov/news-features/understanding-climate/climate-change-atmospheric-carbon-dioxide" target="_blank">National Oceanic and Atmospheric Administration</a> earlier this year corroborates the findings, confirming that CO2 levels in 2018 were higher than at any other point in the past 800,000 years. The last time amounts were this high was more than 3 million years ago, when global temperatures were between 3.6 and 5.4 degrees Fahrenheit higher than during the pre-industrial era, and sea level was 50 to 80 feet higher than today.</p>

Atmospheric researchers have pinpointed the spot on Earth with the cleanest air. It's not in the midst of a remote jungle, nor on a deserted tropical island. Instead, the cleanest air in the world is in the air above the frigid Southern Ocean surrounding Antarctica, as CNN reported.
<p>Air pollution is a global public health problem that claims 7 million lives every year, stunts the growth of children, and increases the risk of heart disease, stroke and pulmonary disorders. So, if you're seeking the cleanest air in the world, you will need to pack a very warm coat.</p><p>The Southern Ocean that surrounds Antarctica has the air that shows the smallest concentration of particles caused by human pollution. The first of its kind study of the bioaerosol composition of the Southern Ocean was conducted by researchers from Colorado State University, according to <a href="https://www.cnn.com/2020/06/02/world/cleanest-air-intl-scli-scn-climate/index.html" target="_blank">CNN</a>.</p>
<p>The study, which described the air as "truly pristine," was published Monday in the journal of the <em><a href="https://www.pnas.org/content/early/2020/05/28/2000134117" target="_blank">Proceedings of the National Academy of Sciences</a></em>.</p><p>The researchers noted that the air that forms the lower clouds in the area was free from any particles produced by man-made activity or dust from other continents.</p>
<p>The study sampling of the air was taken from a research ship that sailed from Tasmania to within 24 miles of the Antarctic ice edge to conduct "bacterial profiling" from air filter samples. The scientists were surprised to find that the air was so clear there was barely any bacterial DNA to profile, according to <a href="https://news.sky.com/story/antarctica-scientists-reveal-location-of-worlds-cleanest-air-11999692#:~:text=Experts%20say%20Antarctica%20appears%20isolated,other%20continents%20to%20the%20north.&text=The%20world's%20cleanest%20air%20is,pristine%22%20and%20unaffected%20by%20pollution." target="_blank">Sky News</a>.</p><p>"We were able to use the bacteria in the air over the Southern Ocean (SO) as a diagnostic tool to infer key properties of the lower atmosphere," said Thomas Hill, a researcher in the Department of Atmospheric Sciences at Colorado State University and a coauthor on the study, in a university <a href="https://engr.source.colostate.edu/csu-atmospheric-scientists-identify-cleanest-air-on-earth-in-first-of-its-kind-study/" target="_blank">statement</a>.</p>
<p>Hill went on to explain how the airborne bacteria is a diagnostic tool to infer the properties of the lower atmosphere.</p><p>"For example, that the aerosols controlling the properties of SO clouds are strongly linked to ocean biological processes, and that Antarctica appears to be isolated from southward dispersal of microorganisms and nutrient deposition from southern continents. Overall, it suggests that the SO is one of very few places on Earth that has been minimally affected by anthropogenic activities," he added.</p>
<p>The scientists analyzed the structure of the airborne microbes, which are dispersed by the wind and travel thousands of miles. The researchers looked at the microbes' DNA, tracked their sources, and analyzed wind trajectories to see where they came from. The microbes they analyzed around Antarctica were from the ocean as opposed to from an airborne pollutant like coal emissions, according to <a href="https://www.cnn.com/2020/06/02/world/cleanest-air-intl-scli-scn-climate/index.html" target="_blank">CNN</a>.</p><p>According to the university <a href="https://engr.source.colostate.edu/csu-atmospheric-scientists-identify-cleanest-air-on-earth-in-first-of-its-kind-study/" target="_blank">statement</a>, the bacterial composition of the microbes also was differentiated into broad latitudinal zones, which suggested that aerosols from distant land masses and human activities, such as pollution or soil emissions driven by land use change, were not traveling south into Antarctic air.</p>

Satellite data collated for the World Resources Institute (WRI) showed primal rainforest was lost across 38,000 square kilometers (14,500 square miles) globally — ruining habitats and releasing carbon once locked in wood into the atmosphere.
<p><br/></p>

<p>The count by the University of Maryland means that 2019 was the third most devastating year for primary forests — comprising old-growth trees and highly diverse wildlife — since scientists began such surveys two decades ago.</p><p>Brazil burnt, logged and bulldozed a third of the area lost, with the Democratic Republic of Congo and Indonesia placed second and a distant third, <a href="https://blog.globalforestwatch.org/data-and-research/global-tree-cover-loss-data-2019" target="_blank">concluded WRI experts from the Global Forest Watch (GFW) project</a>.</p><p>"Primary forest loss was 2.8% higher in 2019 than the year before and has remained stubbornly high for the last two decades despite efforts to halt deforestation," exclaimed the study's authors.</p><p>Brazil's losses preceded President Jair Bolsonaro's legislative moves to loosen rules that would otherwise protect regions from minerals extraction and agriculture.</p>
<p>"Hot spots" identified in satellite images, said the WRI, had corresponded with reports of land-grabs inside the Trincheira/Bacaja indigenous reserve of Brazil's Para state.</p><p>Deforestation across the Amazon was nearing a threshold, calculated another in March, that once crossed would see it morph into arid savannah within 50 years.</p><p>Indonesia was "one of the few bright spots in the global data," wrote WRI fellow Frances Seymour and colleagues, referring to a 5% loss decline since 2018.</p><p>Tougher enforcement and bans on new oil-palm concessions, had all helped, said Arief Wijaya, expert at World Resources Institute Indonesia.</p>
Bolivia Has 80% Higher Loss
<p>In its Global Forest Watch report, the WRI highlighted Bolivia, saying its removal of primary forest and surrounding woodlands — to produce soy and range cattle in 2019 — had been 80% higher than any of its previous years on record.</p><p>"Its highly biodiverse Chiquitano Dry Forest was particularly affected, with reports that nearly 12% of it burned," said the study.</p><p>Other countries with severe losses had been Peru, Malaysia and Colombia, followed by Laos, Mexico and Cambodia — from 1,620 square kilometers and 800 square kilometers in primal forest lost.</p><p><strong>Indigenous Rights Protect Forests Too</strong></p><p>WRI's Seymour said a "mounting body of evidence" suggested that legal recognition of indigenous land rights "provides greater forest protection:</p><p>"We know that deforestation is lower in indigenous territories," Seymour said.</p><p>Global Forest Watch (GFW) project manager Mikaela Weisse said, if left undisturbed, areas stripped of virgin rainforest would "take decades or even centuries" to get back to their original state.</p><p>Those virgin rainforests destroyed comprised but a third of all tree cover (119,000 million hectares, including plantations) lost across the global tropics in 2019, said the study. </p><p>Its authors again warned that slashing forests had major implications for global goals to curb climate change. </p><p>"At least 1.8 gigatonnes of carbon dioxide emissions are associated with 2019 primary forest loss, equivalent to the annual emissions of 400 million cars," said the authors. </p><p>Trees are estimated to absorb about a third of all planet-warming emissions from fossil-fuel combustion, including petrol and diesel-powered vehicles.</p>
Pandemic Weakens Enforcement
<p>The current Covid-19 pandemic had changed dynamics, said Weisse, weakening enforcement of forest-protection laws and leaving rural families desperate to feed themselves back home after losing jobs in cities.</p><p>In April, scientists grouped within the Global Carbon Project estimated that coronavirus-induced economic slowdowns would trim carbon dioxide emissions by more than 5% year-on-year.</p><p>It was "something not seen since the end of World War Two," said project chair Rob Jackson, professor of Earth system science at Stanford University, California.</p><p><span></span>But, recalling the aftermath of the 2008-2009 global financial crisis, climate scientist Corinne Le Quéré at England's University of East Anglia, forecast in April that emissions were likely to rebound if structural changes were not instituted.</p>Glasgow's COP26 Postponed

Researchers have found that warm temperatures in the U.S. this summer are unlikely to stop the coronavirus that causes the infectious disease COVID-19, according to a new study published in the journal Clinical Infectious Disease.
<p>The findings of the scientists refute <a href="https://www.cnn.com/2020/04/08/health/coronavirus-stays-warmer-weather/index.html" target="_blank">President Trump's claim</a> in March that "when it gets a little warmer [the virus] miraculously goes away." It also refutes his insistence in April, when he cited <a href="https://www.marketwatch.com/story/trump-says-coronavirus-could-be-thwarted-by-summer-heat-citing-dhs-study-2020-04-23" target="_blank">Department of Homeland Security data</a>, that summer heat will kill the virus, which led him to wonder about shining a UV light inside the body or injecting disinfectant into the bloodstream, both of which are extremely dangerous.</p>
<p>While the flu is seasonal, researchers who have tested the coronavirus in the lab found that the coronavirus is sensitive to heat and light, but those are at extremes. Summer temperatures may account for a slight decline in cases, but nothing that will allow us to return to normal or kill the virus, as <a href="https://www.newsweek.com/coronavirus-spread-warm-summer-weather-america-study-1507994" target="_blank">Newsweek</a> reported.</p><p>"There is an association between temperature and rate of transmission of SARS-CoV-2 virus which may result in modest decline in the community transmission of SARS-CoV-2 with warmer weather," the researchers wrote in their conclusion, according to <a href="https://www.newsweek.com/coronavirus-spread-warm-summer-weather-america-study-1507994" target="_blank">Newsweek</a>. "This effect is modest, however, and is unlikely to slow down disease spread if containment measures are relaxed."</p>
<p>Higher humidity and warmer temperatures seem to make the virus less stable. In warmer temperatures, the small virus-bearing droplets sent into the air by a cough or sneeze are more likely to attract water vapor, become heavier and drop out of the air before infecting someone. The opposite happens during colder, drier conditions when the droplets are lighter and stay airborne for longer, as <a href="https://www.pix11.com/news/coronavirus/harvard-study-says-warm-weather-probably-wont-slow-covid-19-transmission" target="_blank">WPIX</a> in New York reported.</p>
<p>Co-author Dr. Shiv T. Sehra, assistant professor of Medicine at Harvard Medical School, said in a statement, according to <a href="https://www.newsweek.com/coronavirus-spread-warm-summer-weather-america-study-1507994" target="_blank">Newsweek</a>: "While the rate of virus transmission may slow down as the maximum daily temperature rises to around 50 degrees [Farenheit], the effects of temperature rise beyond that don't seem to be significant.</p><p>"Based on our analysis, the modest association suggests that it is unlikely that disease transmission will slow dramatically in the summer months from the increase in temperature alone."</p><p>The team, led by Harvard researchers, says the findings are evidence we should not forego preventative measures such as social distancing and wearing face masks just because the temperature has warmed up, as the <a href="https://www.dailymail.co.uk/health/article-8380465/Warmer-weather-NOT-stop-spread-virus-without-social-distancing.html" target="_blank">Daily Mail</a> reported.</p>

Several drugmakers and research institutions are working on vaccines, antivirals and other treatments to help people infected with COVID-19. krisanapong detraphiphat / Moment / Getty Images
Researchers at the pharmaceutical giant Eli Lilly announced yesterday that it will start a trial on a new drug designed specifically for COVID-19, a milestone in the race to stop the infectious disease, according to STAT News.
<p>The early-stage trial is the world's first for an antibody treatment that specifically targets the novel coronavirus. Eli Lilly is one of the several drugmakers and research institutions working on <a href="http://www.ecowatch.com/tag/vaccines" target="_self">vaccines</a>, antivirals and other treatments to help people infected with the virus that has already killed over 370,000 worldwide, as <a href="https://www.reuters.com/article/us-health-coronavirus-lilly-treatments/eli-lilly-starts-human-study-of-potential-covid-19-treatment-idUSKBN23825Y" target="_blank">Reuters</a> reported.</p><p>The treatment that Eli Lilly will test uses an antibody that was developed using a blood sample from one of the first U.S. patients to recover from coronavirus. As <a href="https://thehill.com/policy/healthcare/500425-eli-lilly-gives-patients-first-doses-in-trial-of-new-coronavirus-treatment" target="_blank">The Hill</a> noted, antibody treatments that are developed specifically to fight COVID-19 show promise as effective treatments. The drug remdesivir, which has been touted as a potential treatment, already existed and was repurposed to help patients with COVID-19. In trials so far, it has shown moderate results as it slightly shortened the time that patients were infected.</p>
<p>The first phase of the trial will test if the therapy is safe and well-tolerated with results expected later this month. The first COVID-19 patients to receive the new drug are hospitalized at New York University's Grossman School of Medicine in New York, Cedars-Sinai in Los Angeles, and Emory University in Atlanta, Eli Lilly told <a href="https://www.cnn.com/2020/06/01/health/eli-lilly-antibody-therapy-human-trial-covid-19/index.html" target="_blank">CNN</a>.</p><p>The trial will test for side effects and is only being tested in 32 people at the various sites.</p><p>The company said that if the trial shows the medicine is effective against COVID-19, it may be fast tracked through the regulatory process and be available by the autumn, as <a href="https://www.cnn.com/2020/06/01/health/eli-lilly-antibody-therapy-human-trial-covid-19/index.html" target="_blank">CNN</a> reported.</p>
<p>"Until now, scientists have been trying to repurpose medicines, drugs, that were designed for new diseases to see if they work in COVID-19, but as soon as this epidemic started, we got to work making a new medicine against this disease," said Dr. Dan Skovronsky, Eli Lilly's senior vice president and chief scientific officer, as <a href="https://www.cnn.com/2020/06/01/health/eli-lilly-antibody-therapy-human-trial-covid-19/index.html" target="_blank">CNN</a> reported. "Now we're ready and testing it in patients."</p><p>While Indianapolis-based Eli Lilly is developing the drug, the medicine was actually discovered by a Vancouver company, AbCellera. Other companies are also working on developing an antibody drug, too. Biotech firm Regeneron expects to begin a test soon as does a partnership of Vir Biotechnology and GlaxoSmithKline, according to <a href="https://www.statnews.com/2020/06/01/eli-lilly-begins-first-human-tests-of-an-antibody-drug-against-covid-19/" target="_blank">STAT News</a>.</p><p>"We're not racing against each other," said Skovronsky of the other companies, as <a href="https://www.ecowatch.com/r/entryeditor/STAT%20News" target="_self">STAT News</a> reported. "We're racing against the death toll from the virus. I hope there will be multiple successful [antibody drugs]. I expect there will be."</p>
<p>Regeneron Pharmaceuticals has said it plans to start clinical studies in June to test its antibody cocktail treatment and is aiming to have hundreds of thousands of preventative doses available by the end of August, according to <a href="https://www.reuters.com/article/us-health-coronavirus-lilly-treatments/eli-lilly-starts-human-study-of-potential-covid-19-treatment-idUSKBN23825Y" target="_blank">Reuters</a>.</p><p>Lilly's treatment is designed to block it from locking on to human cells, thus neutralizing the virus, as <a href="https://www.reuters.com/article/us-health-coronavirus-lilly-treatments/eli-lilly-starts-human-study-of-potential-covid-19-treatment-idUSKBN23825Y" target="_blank">Reuters</a> reported.</p><p>Scientists at AbCellera and the Vaccine Research Center at the National Institute of Allergy and Infectious Diseases selected the specific antibodies they thought would be most potent. Then Lilly scientists engineered the treatment, known as a monoclonal antibody therapy. Monoclonal antibodies have an approach has worked to treat other illnesses. There are monoclonal antibody therapies that treat HIV, asthma, lupus, Ebola and some forms of cancer, as <a href="https://www.cnn.com/2020/06/01/health/eli-lilly-antibody-therapy-human-trial-covid-19/index.html" target="_blank">CNN</a> reported.</p>
<p>"Ultimately, what we would hope is that this would be an effective treatment that would provide very strongly neutralizing antibodies to lower the virus and help patients recover," said Mark Mulligan, the director of the vaccine center at New York University Langone Health, who is one of the doctors working in the study that Lilly is funding, as <a href="https://www.statnews.com/2020/06/01/eli-lilly-begins-first-human-tests-of-an-antibody-drug-against-covid-19/" target="_blank">STAT News</a> reported.</p><p>"It feels it feels like we're making history," said Skovronsky, according to <a href="https://www.statnews.com/2020/06/01/eli-lilly-begins-first-human-tests-of-an-antibody-drug-against-covid-19/" target="_blank">STAT News</a>. Just three months after Covid-19 became a global pandemic, the pharmaceutical industry has been able to confront it, he said. "This has got to be a new phase in the fight."</p>

The sixth mass extinction is here, and it's speeding up.
<p>A new study, <a href="https://www.pnas.org/content/early/2020/05/27/1922686117" target="_blank">published in the Proceedings of the National Academy of Sciences Monday</a>, found that 515 land <a href="https://www.ecowatch.com/animals/" target="_self">animals</a> are currently on the brink of extinction. That's slightly less than the at least 543 species that disappeared last century. However, these extremely <a href="https://www.ecowatch.com/tag/endangered-species" target="_self">endangered species</a> are expected to disappear in the next two decades, <a href="https://news.stanford.edu/press/view/34340" target="_blank">Stanford University explained in a press release</a>.</p><p>"When humanity exterminates populations and species of other creatures, it is sawing off the limb on which it is sitting, destroying working parts of our own life-support system," study coauthor and Stanford University biologist Paul Ehrlich said in the press release. "The <a href="https://www.ecowatch.com/tag/conservation" target="_self">conservation</a> of endangered species should be elevated to a national and global emergency for governments and institutions, equal to <a href="https://www.ecowatch.com/climate-change/" target="_self">climate</a> disruption to which it is linked."</p>

<p>Ehrlich helped to write a 2015 study confirming that a sixth mass extinction had begun, and he now says the extinction rate is likely higher than previously thought. Species are going extinct at rates hundreds or thousands of times faster than the "background" rate for the last tens of millions of years, and are being killed off by one overriding factor: us. Several specific human actions are behind these losses, including habitat loss, hunting, the introduction of invasive species, pollution, the <a href="https://www.ecowatch.com/tag/wildlife" target="_self">wildlife</a> trade and the climate crisis.</p><p>"The massive losses that we are experiencing are being caused, directly or indirectly, by the activities of <em>Homo sapiens,</em>" the study authors wrote.</p>
<p>To draw their conclusions, the researchers looked at data on 29,400 land vertebrate species compiled by the <a href="https://www.iucnredlist.org/" target="_blank">IUCN Red List of Threatened Species</a> and <a href="https://www.birdlife.org/" target="_blank">BirdLife International</a>, <a href="https://www.theguardian.com/environment/2020/jun/01/sixth-mass-extinction-of-wildlife-accelerating-scientists-warn?CMP=twt_a-environment_b-gdneco" target="_blank">The Guardian explained</a>. Of those species, 515 had populations of fewer than 1,000, and about half of the 515 were down to less than 250 individuals.</p><p>Most of the at-risk species live in the tropics or subtropics. They include the Sumatran rhino, the Clarión wren, the Española giant tortoise and the harlequin frog.</p>

Terrestrial vertebrates on the brink (i.e., with 1,000 or fewer individuals) include species such as (A) Sumatran rhino (Dicerorhinus sumatrensis; image credit: Rhett A. Butler [photographer]), (B) Clarion island wren (Troglodytes tanneri; image credit: Claudio Contreras Koob [photographer]), (C) Española Giant Tortoise (Chelonoidis hoodensis; image credit: G.C.), and (D) Harlequin frog (Atelopus varius; the population size of the species is unknown but it is estimated at less than 1,000; image credit: G.C.).
<p>Because ecosystems are so interconnected, the disappearance of any of these at-risk species would put other species at risk. For example, when sea otters were overhunted in the Bering Sea, the population of sea urchins bloomed, devouring kelp forests and driving the Steller's sea cow to extinction. Eighty-four percent of species with populations under 5,000 live in the same regions as species with populations under 1,000, making such a domino effect more likely.</p><p>"Extinction breeds extinction," the researchers wrote.</p>
<p>The eradication of <a href="https://www.ecowatch.com/tag/biodiversity" target="_self">biodiversity</a> is also a major threat to human civilization. The most timely example is the spread of the new <a href="https://www.ecowatch.com/tag/coronavirus" target="_self">coronavirus</a>, which originated in bats and is believed to have passed to humans through another animal at a wildlife market, the press release explained.</p><p>"Based on our research and what we're seeing, the extinction crisis is so bad that whatever we do in the next 10 to 50 years is what will define the future of humanity," study coauthor professor Gerardo Ceballos of the National University of Mexico in Mexico City told <a href="https://www.bbc.co.uk/news/science-environment-52881831" target="_blank">BBC News</a>.</p><p>The researchers called for a ban on the international wildlife trade, according to Stanford. They have also started an initiative called <a href="https://stopextinctions.org/" target="_blank">Stop Extinction</a> to raise awareness of the biodiversity crisis.</p><p>"In view of the current extinction crisis and the lack of widespread actions to halt it, it is very important that scientists should metaphorically take to the streets," they wrote.</p>
