Taller Arctic Plants Could Speed Dangerous Warming Feedback Loop
A study published in Nature Wednesday examined seven key plant characteristics over 30 years of warming at 117 locations in the Arctic or alpine tundra and found that plants were growing taller at all locations studied.
The international team of scientists, led by Aarhus University in Denmark as well as researchers at the University of Edinburgh and the Senckenberg Biodiversity and Climate Research Center in Frankfurt, also found that taller plant species like vernal sweetgrass, common in the European lowlands, are moving north to locations in Iceland and Sweden, according to a University of Edinburgh press release.
"Quantifying the link between environment and plant traits is critical to understanding the consequences of climate change, but such research has rarely extended into the Northern hemisphere, home to the planet's coldest tundra ecosystems. This is the first time that a biome-scale study has been carried out to get to the root of the critical role that plants play in this rapidly warming part of the planet," University of Edinburgh School of GeoSciences researcher Isla Myers-Smith said in the press release.
Florida International University (FIU) ecologist Steven Oberbauer, who participated in the research, said the increased plant height had serious implications for the state of Arctic soil.
Arctic plants are historically small because the frozen soil does not release many nutrients, but as it thaws, it releases more plant food, as well as something much more dangerous.
"Cold and wet tundra soil holds large amounts of organic carbon as peat. But, as temperatures rise and the soil thaws, the organic matter decomposes, releasing the greenhouse gases carbon dioxide and methane to the atmosphere, causing further warming," Oberbauer said in a FIU press release emailed to EcoWatch. "We're better off if things stay frozen."
Plant height could actually speed up as well as signal the warming process. Taller plants trap snow, which insulates the soil and prevents it from freezing as quickly, the University of Edinburgh press release said.
And the plants are only expected to grow taller as temperatures warm.
"If taller plants continue to increase at the current rate, the plant community height could increase by 20 to 60 percent by the end of the century," Anne Bjorkman of the Climate Research Center said in the University of Edinburgh press release.
A study published in August found that greenhouse gas emissions from lakes formed from melting permafrost could more than double the estimate of how much carbon the Arctic thaw would release into the atmosphere.

Accessibility to quality health care has dropped for millions of Americans who lost their health insurance due to unemployment. New research has found that 5.4 million Americans were dropped from their insurance between February and May of this year. In that three-month stretch more Americans lost their coverage than have lost coverage in any entire year, according to The New York Times.

It's going to be back-to-school time soon, but will children go into the classrooms?
The American Academy of Pediatrics (AAP) thinks so, but only as long as safety measures are in place.
Keeping Schools Safe<p>What will safer schools look like?</p><p>In a <a href="https://jamanetwork.com/journals/jama/fullarticle/2766822" target="_blank">JAMA article</a> published last month, <a href="https://www.jhsph.edu/faculty/directory/profile/1781/joshua-m-sharfstein" target="_blank">Dr. Joshua Sharfstein</a>, a pediatrician and professor at the Johns Hopkins Bloomberg School of Public Health, outlined suggestions — many of which are similar to AAP's.</p><p>Remote learning protocols must stay in place, especially as some schools stagger home and in-building learning. If another shutdown needs to occur, children will rely on distance learning completely, so it must be easy to switch to, he said.</p><p>He suggested giving parents a daily checklist to document their child's health. Kids should be screened quickly on arrival and be given hygiene supplies. Maintenance staff should use appropriate PPE and have regular cleaning schedules. A notification system should be in place if a case is identified, Sharfstein recommended.</p><p><a href="https://www.albany.edu/rockefeller/faculty/erika-martin" target="_blank">Erika Martin</a>, PhD, an associate professor of public administration and policy at University at Albany, said nutrition assistance and health services should be included. She called for tutoring programs with virtual options as well as technology access.</p>
Supporting Staff<p>Teachers and staff will be affected by safeguarding measures, noted <a href="https://directory.sph.umn.edu/bio/sph-a-z/rachel-widome" target="_blank">Rachel Widome</a>, PhD, an associate professor of epidemiology and community health at University of Minnesota.</p><p>"In order for all of the in-school precautions to work well, we'll be asking a lot of teachers and staff," Widome told Healthline. In addition to their usual workload, they'll now be asked to monitor mask-wearing, ensure children are keeping distance, and be aware of any symptoms.</p><p>Along with Sharfstein, Widome called for an increase in financial support. More employees will likely be required so teachers and staff members can keep up with the added demands.</p>
Should Kids Go Back?<p>While these guidelines may help get some schools to reopen, many people don't think children should go back to school over fears they could contract the disease and spread it to other vulnerable family members like grandparents, infant siblings, or their parents.</p><p>In a <a href="https://pediatrics.aappublications.org/content/early/2020/07/08/peds.2020-004879" target="_blank">Pediatrics</a> commentary, <a href="https://www.md.com/doctor/william-raszka-md" target="_blank">Dr. William V. Raszka, Jr.</a>, an infectious disease specialist at The University of Vermont Medical Center, argued that schools should open because school-aged children are far less important drivers of COVID-19 than adults.</p><p>But he says the risk and benefit is not equal among all students ages 5 to 18.</p><p>"Elementary schools are arguably higher priority for face-to-face schooling, since younger children are at lower risk for infection and transmission, and since parental supervision of younger children's distance learning may be particularly challenging," added Sorensen, who penned a <a href="https://jamanetwork.com/channels/health-forum/fullarticle/2767411" target="_blank">June article in JAMA</a> with reopening tips. "That means middle and high schools are more likely to emphasize distance learning."</p><p>Specific student populations, such as special education students and students with disabilities, would also benefit greatly from more time spent in face-to-face environments, Sorensen said.</p>
What Parents Can Do<p>Parents should ask for and receive frequent updates from schools about plans for the fall. They should also be informed about plans if and when COVID infections are identified, Sharfstein said.</p><p>"I'd like to see parents investing now, during the summer, in doing things that can slow and stop the spread of the virus in their communities," Widome said.</p><p>"Now is a good time for kids to practice wearing masks and get used to them as they may be wearing them for longer stretches if school starts up in person," Widome suggested.</p><p>She recommends parents try different mask designs and materials to see what children are more comfortable wearing.</p><p>"If you are using cloth face coverings, it's good to have extras on hand," Widome added.</p><p>Parents should model healthy behavior at home and while out in public — another thing that could affect how well children adapt to reopening practices, Sorensen said.</p><p>"Children may want to know more about face coverings," added <a href="https://www.linkedin.com/in/leescott/" target="_blank">Lee Scott</a>, chairwoman of the Educational Advisory Board at <a href="https://www.goddardschool.com/" target="_blank">The Goddard School</a>. "Dramatic play, such as creating or wearing a face covering, may help some children adjust to this concept." Schools can also show children photos of what faculty members look like in their masks so the students are familiar with that appearance.</p><p>Johns Hopkins University recently released its eSchool+ Initiative, a slew of resources surrounding education during the pandemic. These include a <a href="https://equityschoolplus.jhu.edu/reopening-checklist/" target="_blank">checklist for administrators</a>, report on <a href="https://equityschoolplus.jhu.edu/ethics-of-reopening/" target="_blank">ethical considerations</a>, and a tracker of <a href="https://equityschoolplus.jhu.edu/reopening-policy-tracker/" target="_blank">state and local reopening plans</a>.</p>
