The World Wildlife Fund (WWF) Korea, Green Peace Korea and the Korean Federation for Environmental Movements organized a march against climate change on May 20 at the Cheonggye Plaza in Seoul. Members of the march use the human-lettering technique to form the figure “1.5°C.” Many scientists say the rate of global warming must be limited to 1.5 degree Celsius by the year 2100 if massive catastrophies are to be avoided.
