A gigantic postcard with the writing of 1.5 degrees Celsius is seen on the Aletsch glacier under Jungfraujoch in Switzerland, on Nov. 16, 2018. The gigantic postcard breaking the Guinness World Records was staged just under the Swiss Jungfraujoch on Friday to raise awareness worldwide of the emergency and necessity to fight climate change. At the center of the postcard was a huge slogan reading "STOP GLOBAL WARMING #1.5 °C" to signify the goal of limiting global warming to a maximum of 1.5 degrees Celsius, a target recently set by the Intergovernmental Panel on Climate Change (IPCC).
