An inconvenient moment

摘要

ON DECEMBER 5th Al Gore, the former vice-president who has spent the last three decades warning about the dangers of global warming, tookthe lift to the top of Trump Tower to meet the world's most powerful climate-change sceptic. The scene, captured in "An Inconvenient Sequel: Truth to Power", which had its debut at this month's Sundance Film Festival, conveys Mr Gore's determination never to stop trying to convert unbelievers, no matter how grim the task seems. The film embodies this sober spirit, showing how much worse matters have become since Mr Gore's "An Inconvenient Truth" was released in 2006. The past three years were the three hottest on record.
