Miles Fortune for The New York Times | | The genetic building block of the coronavirus that was detected in a Seattle-area man who was the country’s first confirmed infection has become a crucial clue for scientists trying to understand how the pathogen gained a foothold in the U.S. | | A genetically similar version of the virus — directly linked to that first case in Washington — was identified across 14 other states and around the world. | | Another angle: Two new studies using antibody tests to assess how many people have been infected have turned up higher numbers than some experts had expected. | | Alarming messages that popped up last month on cellphones and social media feeds of millions of Americans warned that the Trump administration was about to lock down the entire country. | | American officials said the operatives had adopted some of the techniques mastered by Russia-backed trolls, such as creating fake social media accounts to push messages to receptive Americans, who in turn unwittingly help spread them. | | Related: China’s state propaganda machine has highlighted other countries’ mistakes during the pandemic while suppressing domestic problems, fueling anger toward foreigners and domestic critics alike, our columnist writes. | | Matthew Abbott for The New York Times | | But what’s most needed is tackling climate change, says one former fire commissioner: “It’s a bit like going to a gas fire and putting out all the houses and burning cars around it but not turning off the gas.” | | PAID POST: A Message From XBrand | Renewable Energy in Today's Age | Look around you...All of the things that you love about this planet can be used to power it. the sun, rain, wind, tides and waves.

Kevin McKenna, a Business editor, suggests this “wonderful account of the avid concert-going life of my friend Ron Louie,” a designer who helped The Times start its first website in the 1990s. He died of complications from the coronavirus last month. | | Today is Earth Day, the annual event established to raise awareness about the state of our planet. John Schwartz, a Times reporter who covers climate change, spoke about what Earth Day means five decades later. | | In broad terms, what has changed since 1970? | | The air over the U.S. is much cleaner, and so is the water we drink in most parts of the country. We don’t use DDT or asbestos. But other threats have arisen. The biggest of those — the issue that wasn’t really on the radar for most people in 1970 — is climate change. Scientific evidence has grown and scientific consensus has gelled, and so now we recognize that there are threats that are more fundamental, and ultimately more harmful, than we ever knew 50 years ago. | | A college student in a gas mask in New York City on Earth Day, 1970. Associated Press | | With the coronavirus crisis dominating our lives, is Earth Day relegated to a second-tier event this year? | | It’s anything but second-tier, but it’s virtual. You won’t have millions marching in the streets, but there are activities all around the world. Young climate strikers are speaking out. The modern-day equivalents of the 1970 “teach-ins” are happening online. | | How can people celebrate Earth Day from home? | | That’s it for this briefing.
