SYDNEY, Australia — In a country where there has always been more space than people, where the land and wildlife are cherished like a Picasso, nature is closing in. Fueled by cli- mate change and the world’s refusal to address it, the fires that have burned across Austral- ia are not just destroying lives, or turning forests as large as na- tions into ashen moonscapes. They are also forcing Austral- ians to imagine a new way of life. When summer is feared. When air filters hum in homes that are bunkers, with kids kept indoors. When bird song and the rustle of marsupials in the bush give way to an eerie, smoky silence. “I am standing here a traveler from a new reality, a burning Australia,” Lynette Wallworth, an Australian filmmaker, told a crowd of international executives and politicians in Davos, Switzer- land, last month. “What was feared and what was warned is no longer in our future, a topic for debate — it is here.” “We have seen,” she added, “the unfolding wings of climate change.” Like the fires, it’s a metaphor that lingers. What many of us have witnessed this fire season does feel alive, like a monstrous gathering force threatening to devour what we hold most dear on a continent that will grow only Learning to Fear Summer in Scorched Australia By DAMIEN CAVE Devastation in New South Wales.

MATTHEW ABBOTT FOR THE NEW YORK TIMES REPORTER’S NOTEBOOK Continued on Page 13 U.S. troops at Ayn al Asad Air Base in western Iraq hunkered down in concrete bunkers last month as Iranian missile strikes rocked the runway, destroying guard towers, hangars and build- ings used to fly drones. When the dust settled, Presi- dent Trump and military officials declared that no one had been killed or wounded during the at- tack. That would soon change. A week after the blast, Defense Department officials acknowl- edged that 11 service members had tested positive for traumatic brain injury and had been evacu- ated to Kuwait and Germany for more screening. Two weeks after the blast, the Pentagon an- nounced that 34 service members had been experiencing symptoms associated with brain injuries and that an additional seven had been evacuated. By the end of January, the number of potential brain inju- ries had climbed to 50. Last week, it grew to 109. The Defense Department said the numbers had increased be- cause of an abundance of caution. It noted that 70 percent of those who tested positive for a trau- matic brain injury had since re- turned to duty. But experts in the brain injury field said the delayed response and confusion had been caused primarily by a problem both the military and civilian world have struggled with for more than a decade: There is no reliable way to determine who has a brain injury and who does not. Top military leaders have for years called traumatic brain inju- ry one of the signature wounds of the wars in Iraq and Afghanistan; at the height of the Iraq war in 2008, they started pouring hun- dreds of millions of dollars into re- search on detection and treat- ment. But the military still has no objective tool for diagnosing brain injury in the field. Instead, medi- cal personnel continue to use a pa- per questionnaire that relies on answers from patients — patients who may have reasons to hide or exaggerate symptoms, or who may be too shaken to answer Military Fights Brain Injuries, But Lacks Test By DAVE PHILIPPS and THOMAS GIBBONS-NEFF Continued on Page 15 Up to 109 U.S. troops may have sustained traumatic brain injuries at Ayn al Asad Air Base in Iraq during an Iranian attack on Jan. 8. SERGEY PONOMAREV FOR THE NEW YORK TIMES In the fall of 2018, Emily’s List had a dilemma. With congres- sional elections approaching and the Supreme Court confirmation battle over Judge Brett M. Kava- naugh underway, the Democratic women’s group was hosting a ma- jor fund-raising luncheon in New York. Among the scheduled head- line speakers was Michael R. Bloomberg, the former mayor, who had donated nearly $6 million to Emily’s List over the years. Days before the event, Mr. Bloomberg made blunt comments in an interview with The New York Times, expressing skepti- cism about the #MeToo move- ment and questioning sexual mis- conduct allegations against Char- lie Rose, the disgraced news an- chor. Senior Emily’s List officials seriously debated withdrawing Mr. Bloomberg’s invitation, ac- cording to three people familiar with the deliberations, who spoke on the condition of anonymity. In the end, the group concluded it could not risk alienating Mr. Bloomberg. And when he ad- dressed the luncheon on Sept. 24 — before an audience dotted with women clad in black, to show soli- darity with Christine Blasey Ford, the woman who accused Judge Kavanaugh of sexual assault — Mr. Bloomberg demonstrated why. “I will be putting more money into supporting women candi- dates this cycle than any individ- ual ever has before,” he declared. It was not an idle pledge: Mr. Bloomberg spent more than $100 million helping Democrats take control of the House of Represent- atives in the midterm elections. Of the 21 newly elected lawmakers he supported with his personal su- per PAC, all but six were women. The decision by Emily’s List, to mute its misgivings and embrace Mr. Bloomberg as a mighty ally, foreshadowed the choice Mr. Bloomberg is now asking Demo- crats to make by anointing him their presidential nominee. There are, after all, numerous dimensions to Mr. Bloomberg’s persona and record that give Democrats pause. A former Re- publican who joined the Demo- cratic Party in 2018, Mr. Bloom- berg has long mingled support for progressive causes with more conservative positions on law en- forcement, business regulation and school choice. He has often given voice to views that liberals find troubling: Over the past week, Mr. Bloomberg’s campaign was on the defensive over past re- cordings that showed him linking the financial crisis to the end of discriminatory “redlining” prac- tices in mortgage lending, and de- fending physically aggressive po- licing tactics as a deterrent against crime. Yet in a primary campaign de- In Bloomberg, Liberals See A Wallet Too Big to Offend Laying the Foundation for a Presidential Bid With Largess to Progressive Causes By ALEXANDER BURNS and NICHOLAS KULISH Michael R.

CALLA KESSLER/THE NEW YORK TIMES Continued on Page 18 SHANGHAI — China has flooded cities and villages with battalions of neighborhood busy- bodies, uniformed volunteers and Communist Party representatives to carry out one of the biggest so- cial control campaigns in history. The goal: to keep hundreds of millions of people away from ev- eryone but their closest kin. The nation is battling the coro- navirus outbreak with a grass- roots mobilization reminiscent of Mao-style mass crusades not seen in China in decades, essentially entrusting front-line epidemic prevention to a supercharged ver- sion of a neighborhood watch. Housing complexes in some cit- ies have issued the equivalents of paper hall passes to regulate how often residents leave their homes. Apartment buildings have turned away their own tenants if they have come from out of town. Train stations block people from enter- ing cities if they cannot prove they live or work there. In the country- side, villages have been gated off with vehicles, tents and other im- provised barriers. Despite China’s arsenal of high- tech surveillance tools, the con- trols are mainly enforced by hun- dreds of thousands of workers and volunteers, who check residents’ temperature, log their move- ments, oversee quarantines and — most important — keep away A Quarantine, Mao-Style, of 760 Million People By RAYMOND ZHONG and PAUL MOZUR China Deploys Citizens to Help Battle Virus Continued on Page 8 WASHINGTON — President Trump suggested in recent days that he had, in fact, learned a lesson from his now-famous telephone call with Ukraine’s president that ultimately led to his impeachment: Too many people are listening to his phone calls. “When you call a foreign leader, people listen,” he ob- served on Geraldo Rivera’s radio show. “I may end the practice entirely. I may end it entirely.” Mr. Trump has always been convinced that he is surrounded by people who cannot be trusted. But in the 10 days since he was acquitted by the Senate, he has grown more vocal about it and turned paranoia into policy, purging his White House of more career officials, bringing back loyalists and tightening the circle around him to a smaller and more faithful coterie of confi- dants. The impeachment case against Mr. Trump, built largely on the testimony of officials who actu- ally worked for him, reinforced his view that the government is Post-Acquittal, Distrust Reigns During a Purge NEWS ANALYSIS By PETER BAKER and MAGGIE HABERMAN Continued on Page 22 WASHINGTON — In an email a few days ago to the 270 lawyers he oversees, Nicola T. Hanna, the United States attorney in Los An- geles, offered a message of re- assurance: I am proud of the work you do, he wrote. Other U.S. attorneys in the Jus- tice Department’s far-flung 93 field offices relayed similar mes- sages of encouragement after President Trump’s efforts to influ- ence a politically fraught case pro- voked the kind of consternation the department has rarely seen since the Watergate era. “All I have to say,” another United States attorney wrote to his staff, “is keep doing the right things for the right reasons.” But the fact that the depart- ment’s 10,000-odd lawyers needed reassurances seemed like cause for worry all by itself. In more than three dozen inter- views in recent days, lawyers across the federal government’s legal establishment wondered aloud whether Mr. Trump was un- dermining the Justice Depart- ment’s treasured reputation for upholding the law without favor or political bias — and whether At- torney General William P. Barr was able or willing to protect it. Trump’s Prying Breeds Anxiety At Justice Dept. Continued on Page 22 This article is by Katie Benner, Sharon LaFraniere and Nicole Hong.
