President Barack Obama will impose even steeper cuts on greenhouse gas emissions from U.S. power plants than previously expected, senior administration officials said Sunday, in what the president called the most significant step the U.S. has ever taken to fight global warming.
A year after proposing unprecedented carbon dioxide limits, Obama was poised to finalize the rule at a White House event on Monday. In a video posted to Facebook, Obama said the limits were backed up by decades of data showing that without tough action, the world will face more extreme weather and escalating health problems like asthma.
“Climate change is not a problem for another generation,” Obama said. “Not anymore.”
Opponents vowed to sue immediately, and planned to ask the courts to put the rule on hold while legal challenges play out. Many states have threatened not to comply.
