House Speaker Nancy Pelosi accused Republicans of calling the climate crisis "a hoax" and undermining Democratic efforts to pass legislation relating to climate change at the COP27 summit.

Pelosi made a surprise appearance Thursday at the COP27 climate summit in Sharm el-Sheikh, Egypt. Pelosi said that there had been ongoing "disagreements" between the parties on climate change, and that Republicans have continuously denied that there is a climate crisis.

"We have to get over that," Pelosi said. "This is urgent, long overdue."

Democratic leaders from other states are echoing Pelosi's sentiments, the chair of the House subcommittee for climate change Kathy Castor saying that Republicans have "not really been partners" and would discontinue her subcommittee if given the chance.

Pelosi's tenure as House Speaker may be approaching its end, according to election forecasts that predict a slight Republican majority in the House. Pelosi has also said that her future in the House may depend on the condition of her husband Paul Pelosi, who was attacked at their home.

President Joe Biden appeared at the COP27 conference Friday, joining delegated cabinet members who are already attending the conference.

"The climate crisis is about human security, economic security, environmental security, national security and the very life of the planet," said Biden.

Biden claimed that the U.S. is a global leader on climate crisis, citing sweeping new laws.

The administrator of the EPA Michael Regan has called climate change a "top priority," and says that voters are "smart enough to see this isn't some long-term conspiracy theory."
