Climate change is undeniable and it is “absolutely essential” the world fight the problem together, United Nations Secretary-General Antonio Guterres argued on Tuesday, as U.S. President Donald Trump considers pulling out of the Paris climate deal.
Trump refused to endorse the landmark climate change accord at a summit of the G7 group of wealthy nations on Saturday, saying he needed more time to decide. He then tweeted that he would make an announcement this week.
“If any government doubts the global will and need for this accord, that is reason for all others to unite even stronger and stay the course,” Guterres said during an event at New York University. “The message is simple: the sustainability train has left the station. Get on board or get left behind.”
“The world is in a mess,” Guterres said. “It is absolutely essential that the world implements the Paris Agreement.”
Trump, who has previously called global warming a hoax, has come under concerted pressure from other world leaders to honor the 2015 Paris Agreement, the first to bind all nations to setting goals to curb carbon emissions.
“We believe that it will be important for the U.S. not to leave the Paris agreement,” said Guterres.
“But even if the U.S. government decides to leave the Paris agreement, it’s very important for the U.S. society as a whole – the cities, the states, the companies, the businesses – to remain engaged with the Paris agreement,” he added.
The United States is the world’s biggest economy and the second largest emitter of greenhouse gases after China.
Guterres said he intends to convene a climate summit in 2019 to review implementation of the global climate deal. He said that currently 147 parties representing more than 82 percent of greenhouse gas emissions have ratified the Paris agreement.
“Climate change is undeniable. Climate action is unstoppable,” he said.
