Mainichi, Sankei, and Nikkei wrote that the U.S. officially left the Paris climate agreement on Wednesday following President Trump’s notification of the withdrawal to the UN a year ago. As the U.S. is the world’s second largest greenhouse gas emitter after China, Mainichi said its departure will undercut global moves to achieve a decarbonized society, underscoring that the remaining signatories will need to reaffirm their commitment to reducing CO2 emissions amid accelerated global warming as evidenced by increasingly frequent heat waves and droughts around the world. Nikkei said that if former Vice President Biden is elected as the next U.S. president, his administration will probably rejoin the climate control framework, adding, however, that the U.S. industrial sector would react sharply to such a scenario since the U.S. is now the world’s largest oil producer as a result of the “shale gas revolution.”
