Story highlights Trump is expected to withdraw from landmark Paris climate accords

Decision will be major break with international partners

Washington (CNN) Democrats quickly denounced the Trump administration's expected move to withdraw from the Paris climate accord Wednesday, calling it a political decision with grave ramifications for the well-being of the planet.

The decision, which will be announced this week, would put the US at odds with nearly every other nation on earth and will be a major break from international partners that would isolate the United States in global efforts to curb global warming. It would also reflect a major reversal of the Obama administration's efforts on climate change and could trigger further efforts to erode the landmark agreement.

House Minority Leader Nancy Pelosi called President Donald Trump's decision "a stunning abdication of American leadership," saying in a statement that pulling out of the pact will result in "a grave threat to our planet's future."

"In walking away from this agreement, the President is denying scientific truths, removing safeguards that protect our health and our environment, protecting polluters and their dirty energy agenda, and threatening our national and global security," she said.

Pelosi added that she believes withdrawing from the pact will have economical ramifications for the US: "Rejecting the pact also sends a strong message to the marketplace to direct innovative, entrepreneurial investments in the clean energy economy elsewhere."
