In Japan, at least 12 people have died, and nearly 10,000 others have been hospitalized, after an intense heat wave settled in over much of the country. In Gifu Prefecture, temperatures topped 105 degrees Fahrenheit Wednesday—the hottest temperature recorded in Japan in five years. The heat wave has prompted concerns about the 2020 Summer Olympics, set to open in Tokyo two years from now. It comes on the heels of the most deadly flooding Japan has seen in decades, after heavy rains killed at least 95 people and forced 2 million more to flee their homes earlier this month. Scientists have linked record heat, heavy rainfall and increased flooding to climate change.
