Scientists are proposing an ingenious but as-yet-unproven way to tackle climate change: spraying sun-dimming chemicals into the Earth's atmosphere.The research by scientists at Harvard and Yale universities, published in the journal Environmental Research Letters, proposes using a technique known as stratospheric aerosol injection, which they say could cut the rate of global warming in half.The technique would involve spraying large amounts of sulfate particles into the Earth's lower stratosphere at altitudes as high as 12 miles. The scientists propose delivering the sulfates with specially designed high-altitude aircraft, balloons or large naval-style guns.Despite the technology being undeveloped and with no existing aircraft suitable for adaptation, the researchers say that "developing a new, purpose-built tanker with substantial payload capabilities would neither be technologically difficult nor prohibitively expensive."They estimate the total cost of launching a hypothetical system in 15 years' time at around .5 billion, with running costs of .25 billion a year over a 15-year period.The report does, however, acknowledge that the technique is purely hypothetical."We make no judgment about the desirability of SAI," the report states. "We simply show that a hypothetical deployment program commencing 15 years hence, while both highly uncertain and ambitious, would indeed be technically possible from an engineering perspective. It would also be remarkably inexpensive."The researchers also acknowledge potential risks: coordination between multiple countries in both hemispheres would be required, and stratospheric aerosol injection techniques could jeopardize crop yields, lead to droughts or cause extreme weather.The proposals also don't address the issue of rising greenhouse gas emissions, which are a leading cause of global warming.And despite the conviction of the report's authors, other experts were skeptical."From the point of view of climate economics, solar radiation management is still a much worse solution than greenhouse gas emissions: more costly and much more risky over the long run," said Philippe Thalmann of the école Polytechnique Fédérale de Lausanne, an expert in the economics of climate change.David Archer of the Department of Geophysical Science at the University of Chicago said, "The problem with engineering climate in this way is that it's only a temporary Band-Aid covering a problem that will persist essentially forever, actually hundreds of thousands of years for fossil fuel CO2 to finally go away naturally."It will be tempting to continue to procrastinate on cleaning up our energy system, but we'd be leaving the planet on a form of life-support. If a future generation failed to pay their climate bill they would get all of our warming all at once." 2830

Sen. Amy Klobuchar, D-Minn., said in an MSNBC interview late Thursday that she is no longer interested in being Joe Biden’s running mate in this fall’s presidential election.Klobuchar was considered among the favorites to be pegged as Biden’s running mate. On Thursday, she took her name out of the running.Klobuchar cited her desire to see a woman of color as part of the reason she is taking herself out of the running. Biden, who previously said he would likely choose a woman as his running mate, has received pressure to choose a minority to be his running mate in the weeks since the death of George Floyd.With Klobuchar’s past as a prosecutor, and given Floyd was killed by officers in Klobuchar’s home state, many pundits believed her viability as a running mate dropped.“After what I have seen in my state, what I have seen across the country, this is a historic moment,” Klobuchar said. “America must seize on this moment and I truly believe, as I told the vice president last night, I think this is a moment to put a woman of color on that ticket."According to an Associated Press report last week, Sen. Kamala Harris and former National Security Advisor Susan Rice were among those being vetted.Klobuchar joined Biden in a crowded Democratic field vying for the party’s presidential nomination. Klobuchar briefly gained momentum following a solid performance in New Hampshire, but following lackluster results in Nevada and South Carolina, Klobuchar exited the race and endorsed Biden the night before Super Tuesday. 1536

School nurses already have a lot of responsibilities, but the possibility of students being back in classrooms this fall may add a new duty: screening for COVID-19."There seem to be no certainties. The guidance changes frequently and there is some concern that the guidance doesn’t take into account the realities in a school building," says Laurie Combe, the President of the National Association of School Nurses.Combe says the pressure will be on school nurses to help screen and isolate any students or staff who could be showing symptoms of COVID-19. But not all schools across the country have the ability to do this."We're supposed to isolate those students or staff members and does a school have the space or capacity to do that?" says Combe.According to the Department of Education, there are 98,000 public schools in the United States. The National Association of School Nurses’ research has shown 25% of those schools have no access to a school nurse."Not part-time, not one nurse covering multiple schools, just no school nurse," says Combe.“COVID has revealed to us is that schools are relying heavily on school nurse expertise to guide their procedures and policies moving forward into reopening,” Combe added. “So what do those schools that don’t have a school nurse do?"Visalia Unified School District in California has about 32,000 students. The district's 12 credentialed school nurses help lead an additional 36 nurses in meeting students' health needs."Our health department reached out and identified the 12 school nurses as emergency disaster workers so instead of enjoying a summer vacation, the nurses are working at the health department and helping to monitor COVID," says the district's Director of Health Services Suzie Skadan. Skadan says that extra experience will be helpful when school is back in session."They will have this additional experience and hands-on happening so they will know what to do when we come back," says Skadan.Visalia unified is working closely with their local health department to put every CDC-recommended protocol in place come the fall."It is an added burden for the school nurse but it's very necessary to keep our students safe. So we think planning ahead and having systems in place will make the best of this situation," says Skadan. Both the National Association of School Nurses and Visalia Unified say ideally there'd be more nurses on hand this fall."Unfortunately, we're having big budget cuts. It's been a bad budget year and then we have COVID on top of that so we are not hiring additional nursing staff. We schedule people around to make things work so hopefully we can manage it this way," says Skadan.While not every school will have the ability to test students for COVID this next school year, the National Association for School Nurses expects more students will be tested. Combe refers to a recent conversation she had with a teacher."I said, ‘So what are you going to do if a child in your classroom starts coughing?’ Normally you would send that child to get some water or you know help them manage that. She said, ‘I’m sending that child to the school nurse,'" says Combe.Combe says nurses focus much of their time on health education for students, faculty and their entire school community, a role that will be amplified come next school year. 3334

SAN YSIDRO (KGTV) -- Local businesses are feeling a one-two punch after the border closure for non-essential travel was extended during the coronavirus pandemic.The owner of El Rincon Restaurant in San Ysidro said the extension is devastating for business."I just found out a couple hours ago that they were going to do this, I had absolutely no clue," Owner Edgar Alaniz said. He was looking forward to the reopening of the border planned for June 22, now pushed back for a third time to July 21.Alaniz said he didn't want to be mad because all of this is to protect our health and safety but it's extremely difficult for businesses to survive after being closed for three months. Alaniz said about 75-80% of their customers come from Mexico. Currently, the business is only seeing about 20% of those customers. "That's what happens when the border is closed for three months, people find different ways and for a restaurant like me, they find a different restaurant," he said.He hopes when the border reopens to welcome them back.Alaniz said they closed the restaurant March 15, and continued with take-out service. Just last week they reopened for dine-in service with protective procedures, like masks and extra cleaning, in place.Alaniz hopes to see more of his neighbors reopening as well, saying he only knows of one other locally owned restaurant in San Ysidro reopening so far.He is confident we will all get through this, "we move forward with strength and a bright vision, that's what it is and that's what it will always be about."The news comes as the U.S., Canada, and Mexico agreed to extend their agreement to keep their borders closed to non-essential travel through July 21 during the coronavirus pandemic."This is an important decision that will keep people in both of our countries safe,” Canadian Prime Minister Justin Trudeau said Tuesday. 1870

SAN MARCOS, Calif. (KGTV) – A group of San Marcos neighbors say that a homeowner is terrorizing the community with threats and harassment, among other complaints. Neighbors are now banding together to sue him with the hope that he'll pack up and leave. Team 10 investigative reporter Jennifer Kastner discovered that federal agents also seized explosives and ammunition from his house, that he wasn't supposed to have. Homeowner Mark Brody, though, denies all allegations of wrongdoing."You don't have to get along with all your neighbors. You don't have to be friends with all your neighbors, but you also don't have to terrorize them," says neighbor Heidi Hafley.Brody’s home sits behind a prominent security camera and high fences. “[It’s] a fortress,” says James Pyer, one of twelve neighbors who are suing Brody, accusing him in the lawsuit of threats, stalking, trespassing, and so on."This has been a nightmare," adds Hafley. She and Pyer got a restraining order against Brody.Court records show that Brody denies harming the neighborhood, but 10News dug into public records.According to a search warrant from last year, state investigators believed that Brody may have been harboring several weapons, even though he'd been banned from having firearms or ammo because of the restraining order. Agents reportedly found and seized 30 pounds of an explosive called tannerite that had to be turned over to a bomb squad. Additionally, they found four ammunition magazines and two rounds of caliber ammunition.“At one point they put everything in the middle of the street and told us to stand back,” says Hafley.This past May, he pleaded guilty to illegally having ammunition. He was given probation and community service.10News confirmed with the San Marcos Sheriff's Station that deputies have been called out to Brody's home more than 30 times since 2014. One Sheriff's report reveals accusations from neighbors that Brody had been shining a flashlight from his truck into Hafley's bedroom. In another report, neighbors claim he yelled that she was a "[expletive]".“I'm the main target now because I push back and I let him know [that] I'm not going to tolerate this,” she tells us.In fact, Brody tried to get a restraining order against Hafley, but failed.The City of San Marcos confirmed with 10News that there have been a number of code compliance violations issued to Brody.A cease and desist order from the City to Brody includes a photo of an unauthorized traffic control sign that Brody allegedly installed. Neighbors say that he spray painted the street, put in a speed bump and put up notices meant to insult his neighbors. Hafley adds that the signs would state, "'Watch for the cows crossing,’ which he's referencing myself and my neighbor. He would [write], ‘The old bat,” which is my nextdoor neighbor [and he would write], ‘The troll,’ which is me."Brody would not do an interview with 10News. In a court response, he wrote that he categorically denies the allegations and claims to have never acted [violently] towards the neighbors."We don't go out of our houses anymore. Children don't play on the street," says Hafley.She and the eleven others on the new lawsuit against him just want him to move out so they can move on. “I don't want any other neighborhood to go through this," she adds.Each neighbor is asking for at least ,000 in damages. The trial date is scheduled for July. 3414
