On the same day that Syria announced its inclusion in the climate agreement, French authorities disclosed that Trump would not be invited to the global summit "Make Our Planet Great Again". And while Syria was not present for the initial climate negotiations, the country's Deputy Minister of Local Administration and Environment, M. Wadah Katmawi, said that it too will now ratify the accord, during a meeting at the start of the COP23 climate change conference in Bonn, Germany.
Though Syria indicated its intention to sign onto the deal, it has not yet submitted its targets to cut greenhouses gases.

"As if it wasn't already crystal clear, every single other country in the world is moving forward together to tackle the climate crisis, while Donald Trump has isolated the United States on the world stage in an embarrassing and unsafe position", an environmental NGO, the Sierra Club, relayed in a statement - criticising the United State's position.

Meyer said businesses, mayors, cities and other groups were also stepping up actions to limit a rise in temperatures that scientists say are stoking more downpours, heat waves and rising sea levels.
"We intend to withdraw from the Paris Agreement as soon as we're eligible to do so", she said.
The treaty states that no countries can state that they will withdraw until November 2019, and that no countries can actually withdraw until Nov. 4, 2020, the day after the next presidential election.
The Trump administration has not said what those terms might be.
The Bonn talks center on creating global guidelines for implementing the Paris agreement, and includes two different American delegations, one from the administration and one from the "We Are Still In" coalition founded by former New York Mayor Michael Bloomberg and California Gov.
The fact that the second-worst emitter of carbon dioxide in the world (behind only China) is the only one against the agreement clearly reflects poorly on the U.S.as a nation.
