A Democratic lawmaker walked out of a moment of silence for the Texas shooting victims on Monday night to protest a lack of action on gun safety after mass shootings in the United States.Rep. Ted Lieu of California, an outspoken critic of President Donald Trump, said he walked out of the House chamber because he wants to pass a universal background check law, a ban on assault rifles and a ban on bump-fire stocks."My colleagues right now are doing a moment of silence," he said during a Facebook Live from the hallway. "I respect their right to do that and I myself have participated in many of them. But I can't do this again. I've been to too many moments of silences. Just in my short career in Congress, three of the worst mass shootings in US history have occurred. I will not be silent. What we need is we need action, we need to pass gun safety legislation now." 880

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 major hospital system is managing the fallout of what may be the biggest medical cyberattack in U.S. history.United Health Services says its company-wide network is currently offline due to a suspected ransomware attack.Ransomware is when criminals encrypt files and demand money for a key to unlock them again.Experts say hospitals may be more susceptible while fighting the coronavirus.“Medical record and medical care facilities are prime targets, not only because of the high value of the information, but also because of the fact that people are terribly busy,” said Alan Katerinsky, a clinical assistant professor at the University at Buffalo.It's not just hospitals. Cyber-attack attempts are up about five times since the pandemic started.People working from home don't have the same corporate protections that are normally in place in an office. IT workers may also be remote.“It might be more difficult to work from home and notice things that are going on, instead of just being on-site, on the premises, and seeing what's going on, on an ongoing basis,” said Steve Beaty, a professor of computer sciences at MSU Denver.After a ransomware attack, if an organization doesn't pay to get their files back, they still have to pay for the cleanup.The criminal may retaliate by releasing the private information, like what happened to a school district in Las Vegas this week.There's recently been talk of legislation to make it illegal to pay such ransoms, which may help deter criminals.“They've upped their game partially because maybe they're seeing that there is going to be a limited amount of time this is actually going to work, at least in some jurisdictions,” said Beaty.Cyber criminals often get in through phishing emails, so training to recognize harmful links may help.Companies can also run tests to see if there are vulnerabilities in their systems, but that's more expensive.It's also important for remote workers to use a VPN for privacy. 1971

A California coffee shop refused service to a customer last week after he insulted a Muslim woman and her headscarf.According to KTLA-TV, the video was shot inside of a Coffee Bean & Tea Leaf store in Riverside, California on Friday. The video opens with a man standing in line for coffee."I said, 'Is this Halloween or something?" the man says."Why did you say that?" the woman filming asks."Why wouldn't I? Why wouldn't I?"The woman filming the encounter then pans over to show herself wearing a niqāb, a Muslim headscarf worn by women that covers all but a woman's eyes."What's wrong with me?" the woman asks again."I don't know, you tell me what's wrong with you," the man says.  705
