At a Glance The mayors announced they would adopt the historic agreement of their own accord.

The mayors said "the world cannot wait, and neither will we."

The list keeps growing.

A group of more than 200 mayors from across the country have joined 10 governors in denouncing President Donald Trump's decision announced Thursday to withdraw the United States from the landmark Paris Climate Accord.

In fact, these mayors and governors have vowed to ignore Trump's decision.

On Thursday, the group of mayors that call themselves the Mayors National Climate Action Agenda took their commitment to the planet a step further by adopting the historic agreement of their own accord.

"As 211 mayors representing 54 million Americans, we will adopt, honor, and uphold the commitments to the goals enshrined in the Paris Agreement," the so-called "climate mayors" announced in a statement . "We will intensify efforts to meet each of our cities’ current climate goals, push for new action to meet the 1.5 degrees Celsius target, and work together to create a 21st-century clean energy economy."

Several cities lit up government buildings with green lights Thursday in support of the climate agreement.

Gov. Andrew Cuomo of New York, Gov. Jerry Brown of California and Gov. Jay Inslee of Washington announced the formation of the United States Climate Alliance following the announcement, a "coalition that will convene U.S. states committed to upholding the Paris Climate Agreement and taking aggressive action on climate change."

"The White House’s reckless decision to withdraw from the Paris Climate Agreement has devastating repercussions not only for the United States but for our planet," Cuomo said in a statement. "This administration is abdicating its leadership and taking a backseat to other countries in the global fight against climate change."

According to CNN, the governors who have vowed to honor the Paris Accord are:

Charlie Baker, Massachusetts

Jerry Brown, California

Kate Brown, Oregon

Andrew Cuomo, New York

John Hickenlooper, Colorado

David Y. Ige, Hawaii

Jay Inslee, Washington

Dannel P. Malloy, Connecticut

Terry McAuliffe, Virginia

Gina M. Raimondo, Rhode Island

Of note, Mayor William Peduto of Pittsburgh is among the group of committed mayors. Some might say his inclusion comes as an ironic twist, considering Trump's comments during the announcement that he was "elected to represent the citizens of Pittsburgh, not Paris."

In response, Peduto took to Twitter and seemed none too pleased that Trump signaled out his city and noted in a tweet that "Hillary Clinton received 80 percent of the vote in Pittsburgh." He again vowed that his city would adhere to the Paris agreement.

"This city does not support the initiatives that he is doing. This city is adamantly opposed to them," Peduto told reporters following Trump's announcement. "For him to use this city as his example of who he is elected to represent — he’s not representing us at all, or not very well."

Prior to the announcement, the mayors sent an open letter to Trump , urging him to remain in the agreement.

"Climate change is both the greatest single threat we face, and our greatest economic opportunity for our nation," the mayors wrote. "That is why we affirm our cities' commitments to taking every action possible to achieve the principles and goals of the Paris Climate Agreement, and to engage states, businesses and other sectors to join us."

After the announcement, the mayors said they would continue to lead in the fight for future of the planet.

"We are increasing investments in renewable energy and energy efficiency," the mayors wrote. "We will buy and create more demand for electric cars and trucks. We will increase our efforts to cut greenhouse gas emissions, create a clean energy economy, and stand for environmental justice. And if the President wants to break the promises made to our allies enshrined in the historic Paris Agreement, we’ll build and strengthen relationships around the world to protect the planet from devastating climate risks."

They concluded: "The world cannot wait — and neither will we."
