More than 30,000 protesters gathered in sweltering heat in South Korea’s capital on Saturday, demanding that the government take more forceful action against global warming. The protest was organized by the 907 Climate Justice March Group committee after South Korea’s Supreme Court ruled last month that South Korea’s climate change law does not protect basic human rights and does not include goals to protect future generations. The night-time temperature in Seoul has not been below 25 degrees Celsius for 20 consecutive nights.
