LONDON Climate change turbocharged the winds and rain of Typhoon Gaemi, which killed dozens of people across the Philippines, Taiwan and China earlier this year, a group of scientists said on Thursday. Gaemi skirted the Philippines in July, triggering floods and landslides that killed at least 40 people, before making landfall in Taiwan and China. In China, the weather system caused torrential downpours that killed 50 people and prompted authorities to evacuate 300,000. World Weather
