A locked-down pandemic-struck world cut its carbon dioxide emissions this year by 7%, the biggest drop ever, new preliminary figures show.The Global Carbon Project, an authoritative group of dozens of international scientists who track emissions, calculated that the world will have put 37 billion U.S. tons (34 billion metric tons) of carbon dioxide in the air in 2020. That’s down from 40.1 billion US tons (36.4 billion metric tons) in 2019, according a study published Thursday in the journal Earth System Science Data.Scientists say this drop is chiefly because people are staying home, traveling less by car and plane, and that emissions are expected to jump back up after the pandemic ends. Ground transportation makes up about one-fifth of emissions of carbon dioxide, the chief man-made heat-trapping gas.“Of course, lockdown is absolutely not the way to tackle climate change,” said study co-author Corinne LeQuere, a climate scientist at the University of East Anglia.The same group of scientists months ago predicted emission drops of 4% to 7%, depending on the progression of COVID-19. A second coronavirus wave and continued travel reductions pushed the decrease to 7%, LeQuere said.Emissions dropped 12% in the United States and 11% in Europe, but only 1.7% in China. That’s because China had an earlier lockdown with less of a second wave. Also China’s emissions are more industrial based than other countries and its industry was less affected than transportation, LeQuere said.The calculations — based on reports detailing energy use, industrial production and daily mobility counts — were praised as accurate by outside scientists.Even with the drop in 2020, the world on average put 1,185 tons (1,075 metric tons) of carbon dioxide into the air every second.Final figures for 2019 published in the same study show that from 2018 to 2019 emissions of the main man-made heat-trapping gas increased only 0.1%, much smaller than annual jumps of around 3% a decade or two ago. Even with emissions expected to rise after the pandemic, scientists are wondering if 2019 be the peak of carbon pollution, LeQuere said.“We are certainly very close to an emissions peak, if we can keep the global community together,” said United Nations Development Director Achim Steiner.Chris Field, director of the Stanford Woods Institute for the Environment, thinks emissions will increase after the pandemic, but said “I am optimistic that we have, as a society learned some lessons that may help decrease emissions in the future.”“For example,” he added, “as people get good at telecommuting a couple of days a week or realize they don’t need quite so many business trips, we might see behavior-related future emissions decreases.”___Follow AP’s climate coverage at https://www.apnews.com/Climate___Follow Seth Borenstein on Twitter at @borenbears .___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

A drug used to euthanize animals has been found in canned dog food, prompting a recall.Low levels of the drug pentobarbital were detected in cans of Gravy Train dog food produced by the J.M. Smucker Company, the FDA said in a statement Friday. Pentobarbital is most commonly used as a sedative, anesthetic or to euthanize animals, it said."Pets that eat pet food containing pentobarbital can experience drowsiness, dizziness, excitement, loss of balance, nausea, nystagmus (eyes moving back and forth in a jerky manner) and inability to stand. Consuming high levels of pentobarbital can cause coma and death," it said.The FDA said its preliminary evaluation of the testing results of Gravy Train samples indicated the low levels found were unlikely to pose a health risk to pets."However, any detection of pentobarbital in pet food is a violation of the Federal Food, Drug, and Cosmetic Act—simply put, pentobarbital should not be in pet food," it said. 'Single supplier' 984

A Clarksville teacher was charged with assault after an incident with a student during a field trip to Nashville was reported to police.According to an affidavit from Metro Nashville Police, Robert Neitzke – a teacher at Clarksville Academy – was arrested after he allegedly grabbed a student by his throat and pushed him against a wall.The alleged incident happened on March 3 while a group of students were staying at the Renaissance Hotel in Nashville. The police report said that Neitzke was the only adult on the trip.Around 11 p.m., Neitzke was reportedly trying to give students instructions for the next day and had to stop several times to get their attention. That’s when one of the students asked, “can we hurry this up,” and Neitzke allegedly approached the student and started to grab him. Police said Neitzke then said “it would be funny if your head hit the wall” before backing up and then grabbing the student by the neck before pushing him against the wall.The student told officers that he was able to say "get off me" and push him back. He told police that while he had no visible injuries, the squeezing of his neck caused “some discomfort.”Several other students were interviewed and all gave a very similar account of the incident, according to the report. Neitzke was placed on administrative leave and has since resigned. Clarksville Academy released the following statement, in-part:  1448

A historic and disproportionate number of women have left the workforce since the start of the pandemic, and new studies are showing many more are still considering downshifting their career.“I had just found another position that I was going to start part-time in addition to the one I had, and I was hoping to build my career with that,” said Ashley Stewart in Virginia.Stewart is a mother of three young children, who at the beginning of the year was hoping to transition to full-time work as an occupational therapist. However, when the pandemic hit, she had to reevaluate what was best for her family.“I switched to doing just a couple of virtual sessions on my computer during the week,” said Stewart. "It ended up that it was just too much to handle here, with the kids screaming in the background or climbing on me while I am trying, so I ended up stopping altogether.”It was a bittersweet decision. She was sad to halt a blossoming career, but grateful her family could afford to make that decision. She felt it was safer for her children and worth the sacrifice on her end. Stewart’s decision has become a common one for women across the country. The latest data from the Department of Labor shows that between August and September, 865,000 women dropped out of the labor force, compared to 216,000 men. That is essentially women dropping out of the workforce four time faster than men.“The number of women who have left is startling,” said C. Nicole Mason. “Because at the beginning of the year, we were celebrating the fact that women were 50% of the workforce, so we have lost significant gains since then.”Mason is the president and CEO of the Institute for Women’s Policy Research.“We can draw the direct line between the lack of childcare and daycare closures to women exiting,” said Mason.Experts, like Mason, are concerned a decade or more of women’s equality and progress in the workforce could be erased, if women continue to drop out of the labor force at this rate.“Employers have a role to play by making sure workplace policies are flexible, providing access to childcare,” said Mason. “The federal government has a role to play by instituting a national care infrastructure that will do more to keep women in the workforce by making sure they have childcare and other supports."Many companies have begun to offer more flexibility during the pandemic, but the data indicates more may need to be done. In terms of government responding to this disproportionate loss of women in the workforce, the childcare industry has been calling on Congress for funding for weeks. The industry’s plea is not only to save providers but to support women needing their service to go back to work. Congress has not been able to make true progress toward a new stimulus package, for months now.In addition to the disproportionate number of women who have already left the workforce, a new study shows another one in four women are considering leaving or downshifting their careers because of COVID-19. 3014

A federal court on Thursday ordered the Environmental Protection Agency to ban a pesticide used widely in farming.The 2-1 ruling on a lawsuit brought by public health groups and state attorneys general ordered the agency "to revoke all tolerances and cancel all registrations for chlorpyrifos within 60 days."Concerns that the insecticide can harm the brain and nervous system led to the EPA banning the household use of chlorpyrifos in 2000. But the agency had allowed the chemical to continue to be used in commercial agriculture, where, some scientists say, it can be used in safe quantities. 603
