(Although the cities cannot technically join the agreement as they're not members of the United Nations, they can informally agree to its guidelines.) According to a statement from Paris Mayor Anne Hidalgo, who serves as the chair of C40, an worldwide coalition of mayors focused on climate action, the cities remain united in their goals.
He said he would notify the UN Secretary General and the climate change secretariat that USA cities, states, businesses and others would aim to meet the US's commitment to reducing emissions 26 per cent below the 2005 levels by 2025.
The UN World Meteorological Organisation said that, in the worst scenario, the United States pullout could add 0.3° to global temperatures by the end of the century. "It is time for all of us to stand up, organize, fight back, and channel our energy into grassroots political action". "Do you know what he believes?"
Mr Trump said the 2015 Paris agreement would cost American jobs.
In the wake of the Trump administration's sudden withdrawal from the global stage, local leaders - especially, though not limited to, those in progressive areas of the country - are recommitting to their work on climate policy. "The Secretary-General remains confident that all other parties to the Paris agreement will continue to demonstrate vision and leadership, along with very many cities, states and businesses in the United States and around the world by working for the low-carbon, resilient economic growth that will create quality jobs and markets for 21st century economic prosperity", the statement by the UN Chief said.

Criticism of Trump's decision rolled in from blue-chip companies like Facebook, Apple, Ford Motor and Microsoft, while the response from fossil-fuel groups with the most to gain from a relaxation of U.S. carbon emissions standards was muted.
Sir Simon Hughes, the Lib Dems' former deputy leader, also criticised Mrs May, saying: "Yet again, the UK Prime Minister appears unwilling to be critical on an issue of substance and just when our economy is going to depend more and more on renewable energy, which can really help with climate change".
"(Climate change) is undeniable.
"Does the president still believe that global warming is a hoax?"
"We think that is unrealistic because if the countries implement Paris they will likely continue with similar policies".
Peabody Energy, America's biggest coal mining firm, said the agreement would have badly affected the USA economy.
The minister said that it is not now known what kind of impact the decrease in US funding to support developing countries will be.
