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 hacker who claims to have gotten access to President Donald Trump’s personal Twitter account by guessing his password will not face charges, according to reports, because the man acted “ethically” following getting access.Dutch prosecutors say Victor Gevers did get access to the @realDonaldTrump Twitter account by guessing “MAGA2020!” as the password in late October of this year, saying that Gevers shared screenshots from inside the account, according to the BBC.At the time, the White House and Twitter denied it had been hacked.Gevers, a cyber-security researcher, said he was doing a semi-regular sweep of Twitter accounts associated with the U.S. election when he correctly guessed Trump’s password.Investigators in the Netherlands said Gevers was investigating the strength of the password based on “major interests involved if this Twitter account could be taken over so shortly before the presidential election.”“We believe the hacker has actually penetrated Trump’s Twitter account, but has met the criteria that have been developed in case law to go free as an ethical hacker,” reads a statement from the public prosecutor’s office, the Guardian reported.Investigators say Gevers met the standard for “responsible disclosure.”He has publicly shared how he guessed the password, and tweeted October 22, following the alleged hack, a warning possibly aimed at the president urging people to use two-factor authentication. This is a way to make hacking more difficult by requiring two forms of authentication when account details are changed. 1562

A group of NFL owners are accusing Jerry Jones of "damaging the league."Jones, who owns the Dallas Cowboys, is locked in a bitter feud with the owners of other teams over NFL Commissioner Roger Goodell's contract extension.A lawyer for the NFL's compensation committee, which is responsible for negotiating Goodell's extension, sent a letter to Jones' attorney on Wednesday urging the Cowboys owner to support the committee and not "attempt to sabotage" its efforts.The letter, of which CNNMoney obtained a copy, said Jones' "antics, whatever their motivation, are damaging the league and reflect conduct detrimental to the league's best interests."The compensation committee is composed of six owners. All the other NFL owners also received a copy of the letter, which was first reported by The Wall Street Journal.Jones' lawyer didn't immediately respond to a request for comment late Wednesday. The Cowboys declined to comment.The language used in the letter follows reports that other owners are considering whether to strip Jones of his beloved Cowboys. On Tuesday, Jones dismissed the possibility as well as reports he had received a cease-and-desist warning from the committee earlier in the week."If somebody is asserting that, they are not knowledgeable about how things work in the NFL," he told a Dallas radio station.The letter is the latest development in a saga that has pitted Jones against many within the NFL, exposing deep divisions.Jones has questioned Goodell's leadership and his handling of players who protest racial injustice by kneeling during the National Anthem.He's also upset over Goodell's treatment of his star running back, Ezekiel Elliott, who was suspended six games earlier this season for domestic violence allegations.Despite his recent clashes with the league, Jones has had a lot to do with how things work in the NFL.Besides winning three Super Bowls and a spot in the Pro Football Hall of Fame, he helped Las Vegas and Los Angeles land NFL teams. And he was instrumental in securing the league's lucrative TV rights deal.But his threat to sue fellow members and the league may be a step too far.The letter sent on Wednesday said Jones is trying to "deliberately interfere" with the committee's work.Jones said he's fighting for transparency in the negotiations and wants all the owners to approve any deal with Goodell. He has said that "well over half" of owners agree with him. But all 32 owners agreed in May to give the compensation committee the power to decide whether to extend Goodell's contract, according to a league spokesman.The committee said in the letter that it has continued to keep owners informed.At one point, Jones was a non-voting honorary member of the committee, but was dismissed after he made his threat to sue.The letter referenced his dismissal and accused him of circulating old and misleading documents in his quest for transparency."Someone who is genuinely concerned 'that the owners know the truth about the negotiations' would not deliberately distribute such an outdated document ... or threaten to sue the league and its owners if he does not get his way," it said. 3170

A former Israeli government official says extraterrestrials have been in contact with Earth, and that President Donald Trump is aware of an agreement between the U.S. and the aliens.The official, Haim Eshed, is the former head of Israel’s Defense Ministry’s space directorate and made his comments during an interview with the Yediot Aharonot newspaper. Eshed is a respected professor and retired general, according to NBC News.Parts of the interview, originally given in Hebrew, were translated over the weekend and published in the Jerusalem Post."The Unidentified Flying Objects have asked not to publish that they are here, humanity is not ready yet," claims Eshed.Eshed described a kind of galactic federation that had signed agreements of cooperation. He claims there is an agreement between the U.S. government and the aliens to conduct experiments.He added that Trump is aware of the extraterrestrials’ existence and was asked not to reveal any information in order to prevent “mass hysteria.”Officials from the White House and Israeli government did not respond to media requests for comment. A spokesman for NASA told NBC News that one of the agency’s key goals was to search for signs of life in the universe, but that they had yet to find any.Eshed’s ideas were shared in more details in a book published in November called “The Universe Beyond the Horizon - conversations with Professor Haim Eshed.” 1420
