President Trump's decision to withdraw from the Paris climate change agreement is a top focus of a United Nations climate summit in Morocco this week, where the state of California is seen as key to continuing momentum on Paris despite the administration's decision.

The second annual "Climate Chance Summit" entered its second day of deliberations to bring together 5,000 representatives from local governments, provinces and states on implementing the 2015 climate change agreement agreed to by their respective countries in Paris.

The United Nations Framework on Climate Change hosted the summit in Agadir, Morocco, with California representing the United States.

The summit is expected to lay the foundation of a November meeting of the signatories of the Paris Agreement in Bonn, Germany, to decide on the next steps in meeting the goals of the 2015 deal.

On day one, California was hailed as key to the summit, as the state's "presence demonstrates the important and effective mobilization of non-state actors in the United States" toward meeting the Paris Agreement, according to a Monday communique. California and other states have agreed to continue meeting the goals of the Paris deal in the wake of Trump's decision.

Trump's June 1 decision to exit the deal was not discussed in the U.N. climate framework's first communique. Instead, it focused on paying tribute to Matt Rodriquez, secretary of state for Environmental Protection of California, as a "key figure" from the United States at the summit.

On Tuesday, however, the second official communique showed that the focus of the summit seemed to revolve around Trump's withdrawal.

The second day closed in Morocco with sub-national governments declaring their allegiance to the goals of the Paris climate pact, with the first part of the declaration reading: "U.S. non-state actors reaffirm their mobilization and ambitions for the fight against climate change, despite the announcement of the withdrawal of the United States from the Paris Agreement."

The Tuesday communique also revealed that although Trump's decision did not make it into the official first-day communique, Monday was all about easing officials' apprehension over the president's decision to leave the deal.

"The first day of the Climate Chance 2017 summit brought together nearly 5,000 non-state actors committed to climate change to discuss the state of play of the climate negotiations with the major actors of the Paris ... in particular following the announcement of the withdrawal of the United States from the Paris Agreement," the Tuesday statement read.

"The second day is devoted to elected officials," it read. "It provides answers to urban management issues and encourages reflection on urban strategies aimed both at increasing the adaptability of cities and mitigating their greenhouse gas emissions."
