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 doctor is opening up about working at one of the first hospitals in the country dedicated solely to treating people with severe cases of COVID-19.“Hope gave way to frustration as heartwarming images of mutual sacrifice were replaced by images of protest about the sanctity of dining out and getting haircuts,” said Dr. Ben Trappey at Bethesda Hospital in St. Paul, Minnesota. “Now, even frustration has given way to bone deep sense of weariness and resignation. I’m running on fumes.”Trappey spent nearly three months away from his wife, quarantining at a hotel while caring for patients at Bethesda Hospital near Minneapolis.He destresses through reflective writing and teaches it to other residents and physicians.His essay “Running on Fumes” was recently published in the Journal of the American Medical Association (JAMA). It reflects how he feels still being on the front lines of COVID-19, but not feeling like the rest of the world is behind him.“The thing that made me feel most supported early on was just that everybody was making these sacrifices together and now when there are so many people who refuse to acknowledge that a sacrifice even needs to be made is really frustrating,” said Trappey.He says one of his challenges is not knowing which COVID-19 patients will get better.Many hospitals have provided support like counseling and buddy systems.Trappey is now on parental leave at home with his wife and newborn son.“It’s hard to think about what things will be like as we get further into the fall and we have other respiratory viruses in place as well. It’s pretty worrisome, so I’m just trying not to let myself think too much about that,” said Trappey.The doctor says he hopes people realize they're not alone in the pandemic. 1758

A carjacker is dead on Milwaukee north side, shot by the man he was trying to rob according to police.Officers said the shooter was legally carrying a gun and is now cooperating with them.People living near the incident said it is concerning since the attempted carjacking happened around the same time they start their day.Just before 6 a.m. Monday, police said a 21-year-old with a gun tried to steal a car from a man on his way into work. "It's really sad that a person would do that as far as try to rob someone who was going to work," said Kinyata Hendriex who lives nearby."A lot of young people think this is a game and that's it's just only fun. This is not fun," said Milwaukee Police Captain Andra Williams.The victim had a concealed carry permit, pulled out his own gun and fired. People say even if the shooting was justified it is not something someone should have to live with."Life threatened, if you got the opportunity then certainly it's within their right to go ahead and do that. It's sad," said nearby business owner Sean O'Byrne."I think it's a tragic situation. It's sad," said Hendriex.Police don't think the man who was shot was alone. They are looking for another vehicle that was seen with the carjacker.  According to police, it will be up to the District Attorney's office to determine if the shooting was justifiable. 1365
