Wildlife officials and environmental groups in Florida are raising an alarm over the unprecedented die-off this year of manatees, the large, slow-moving sea animals that are the southeastern U.S. state’s official marine mammal.  The latest figures from the Florida Fish and Wildlife Commission show that as of October 15, 974 manatees have been found dead, more than twice the number that died all of last year and more than any other year on record. The number represents more than 10% of the total population of manatees in the state.  Officials …

Coal-rich Australia unveiled a much-delayed 2050 net zero emissions target Tuesday, in a plan that pointedly dodged thorny details or near-term goals ahead of a landmark UN climate summit.  Widely seen as a climate laggard, Australia is one of the world’s largest coal and gas exporters.    For the last eight years, its conservative government has resisted action to reduce emissions, routinely approving new coal projects and peddling skepticism about climate change.  Under domestic and international pressure, Prime Minister Scott Morrison on Tuesday announced a shift in approach and acknowledged the “world is …
