SEOUL, South Korea (AP) — Fans fainting at a baseball park. A doctor advising people to eat dog meat to promote stamina. The scenes caused by a record heat wave in Northeast Asia illustrate how extreme temperatures have gripped South Korea, North Korea and Japan. North Korean authorities have issued a heat wave advisory in many areas and called for people to take safety steps to avoid heat-related health problems. In a Cabinet meeting Tuesday, President Lee Jae Myung instructed officials to view the ongoing heat wave as “a national disaster” and make all-out efforts to protect lives.
