Greenland Melts at Never-Before Seen Rates as Heat Wave That Baked Europe Moves North
Scientists say 2019's melt might be more extreme than the melt that broke records in 2012, when around 98 percent of Greenland's ice sheet experienced surface melting, The Washington Post reported. If the entire ice sheet melted, it would contribute 23 feet to global sea level rise.
That much melt won't happen right away. A recent study found that, if greenhouse gas emissions continue at current rates, it would still take a millennium for the ice sheet to melt entirely. That doesn't mean all of the consequences of today's melting will be delayed far into the future, however. The same study found the ice sheet would contribute as many as 63 inches to sea level rise in the next 200 years if emissions are not reduced, enough to flood Miami Beach, New Orleans and parts of New York and Boston, according to Grist.
And this summer's extreme melt could also have more immediate consequences. The fresh meltwater entering the North Atlantic could cause more storms in Northwest Europe, and the influx could raise global sea levels by more than one millimeter globally and two or more millimeters in the tropics, Geological Survey of Denmark and Greenland climatologist Jason Box told CNN.
"Whatever happens in Greenland radiates its impact down," Box said.
And what's happening in Greenland is unprecedented. Box told The Washington Post that two locations were recording more melt than in 2012. One, 75 miles east of the capital of Nuuk, had lost 8.33 feet of water as of Wednesday. The second, 497 miles north, had lost 7.38 feet, twice the average melt at that location over the last ten years.
Greenland's ice sheet measured its record surface temperature Wednesday and its record melt rate Thursday, losing 12.5 gigatons of ice, University of Liège polar scientist Xavier Fettweis tweeted.

Today is its biggest melt day. More than 12 billion tons of water will have entered the ocean by tonight, permanently raising sea levels.

Polar researchers have posted some dramatic images of the heat wave on social media. Climate scientist Irina Overeem shared a video of meltwater rushing past a monitoring station she placed in Western Greenland eight years ago, as meteorologist Eric Holthaus reported for RollingStone.
"With the exceptional heat wave coming I have my fingers crossed for it not being washed away," she tweeted.

Meanwhile, researchers at Zackenberg Research Station in Northeast Greenland posted a photo of themselves in shorts, as temperatures passed a balmy 19 degrees Celsius Wednesday.
The recent #Greenland #heatwave has been felt most in the NE where very few peole live and we have very few observations, however the research station at Zackenberg is an exception - imporessive temperatures here! https://t.co/3wX2oIO5dx— Greenland (@greenlandicesmb) August 1, 2019
The heat and melting in Greenland is a frightening sign of the climate crisis: Ice core samples show that melt days like those seen this week occurred very rarely in the past thousand years, but global warming caused by the burning of fossil fuels is making them more likely, Holthaus wrote.
"This melt event is a good alarm signal that we urgently need change our way of living," Fettweis told Holthaus.
But if we do change, there is still hope we can stop the worst from happening. Scientists say melt in Greenland won't become irreversible until global temperatures reach 1.5 to two degrees Celsius above pre-industrial levels.
"That means whether or not Greenland's ice sheet melts completely is almost entirely in human control: A full-scale mobilization — including rapidly transforming the basis of the global economy toward a future where fossil fuels are no longer used — would probably be enough to keep most of the remaining ice frozen, where it belongs," Holthaus concluded.

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>
