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 cloud of dust from the Sahara Desert in North Africa is now sitting over the Southeastern U.S. and the Gulf of Mexico. It brings increased particles into the air and could cause respiratory issues while many states struggle with COVID-19 cases.An animation from NASA shows the movement of the plume and where it sits as of June 25. Saharan dust plumes moving east-to-west across the Atlantic are nothing new. However, this plume is thicker than normal, bringing higher levels of desert dust to the atmosphere. 519

A longtime national security aide to President-elect Joe Biden, Antony Blinken, is the leading contender to become Biden's nominee for secretary of state. Multiple people familiar with the Biden team’s planning tell The Associated Press that Blinken is at the front of his choices to be America's top diplomat. Blinken served as deputy secretary of state and deputy national security adviser during the Obama administration. If chosen and confirmed, he would be a leading force in Biden's bid to reframe the U.S. global relationship after four years in which President Donald Trump questioned longtime alliances.The President-elect is moving quickly to fill out his administration and could name other top Cabinet nominations as early as next week. Biden’s team is considering releasing his Cabinet picks in groups focused on a specific topic area. Such a move is intended to deliver the message that Biden is intent on preparing for the presidency even as President Donald Trump refuses to concede and attempts to subvert the election results. 1052

A jury in Middlesex County, New Jersey, awarded million in compensatory damages on Thursday to a man who got cancer after decades of using talcum powder. His wife was awarded million in damages.Banker Stephen Lanzo said he used Johnson & Johnson products like Shower to Shower and Baby Powder for more than 30 years, and he claimed that inhaling the powder caused his mesothelioma, an aggressive and deadly cancer that impacts the lining of the lungs.Deposits of talc, one of the Earth's softest minerals, are often located near deposits of the minerals that constitute asbestos, and studies have shown the risk of cross-contamination during mining. Johnson & Johnson said its talc products do not contain asbestos, which, it noted, has been a legal requirement since the 1970s. 801
