A butterfly lit upon an aid worker’s hand in Turkey, pausing for several seconds to drink water from the worker’s palm. The scene happened near a southern Turkish town, where firefighters have been battling catastrophic wildfires. Fires have devastated parts of Turkey in recent weeks; Turkish officials said they were the worst fires the country has ever seen. The fires owe their source to unusually dry weather. That weather, scientists say, has been caused in part by climate change.
