The following editorial originally appeared in the Los Angeles Times:
Representatives from nearly every country on Earth met in Paris five years ago and promised to work together in an unprecedented effort to limit global warming to 2 degrees Celsius above preindustrial levels, with a preferred goal of capping the rise at 1.5 degrees. It took a lot of maneuvering and diplomacy by the Obama administration to reach that agreement after a similar effort six years earlier in Copenhagen failed.
What changed in the interim was strengthened resolve by the U.S. and a decision by China, whose cities were choking on coal-fired smog, to join in the move to a new energy future. Even though some climate advocates argued that the Paris Agreement fell short of what was necessary to achieve its goals, it stood as a framework for moving forward.
But then things unraveled with the election of President Donald Trump, who denounced the agreement, then reneged on the United States’ promises by walking away from it — making the U.S. the only nation in the world to not be part of the pact.
So here we are five years after the Paris Agreement, still spewing carbon. In fact, the Emissions Gap Report that the United Nations issued Dec. 9 says that even if countries keep the promises they made under the Paris Agreement, the global temperature would still rise to 3.2 degrees Celsius above preindustrial levels by the end of the century — far too warm.
