Print article WASHINGTON — World leaders shared tales of climate-friendly breakthroughs — and feverish quests for more — to close President Joe Biden’s virtual global climate summit on Friday, from Kenyans abandoning kerosene lanterns for solar to Israeli start-ups straining for more efficient storage batteries. It was an exhortational end to an unusual pandemic-era summit hosted from a specially created TV-style set in the White House East Room. Biden’s two-day gathering briefly united the heads of global rivals America, China and Russia — on screens, anyway — long enough to pledge cooperation on climate. It also saw the U.S. and a half-dozen allies commit to significant new efforts and financing to reduce climate-damaging emissions.
