Leaders of China, Russia, Germany, Britain and the EU have spoken in favour of the Paris agreement and appealed to President Trump to not abandon the climate accord when he announces his decision later today.
World leaders pledged on Thursday to keep up the fight against global warming and urged Donald Trump to be part of that effort, hours before the US president was due to announce whether he would pull out of the Paris climate accord.
Chinese Premier Li Keqiang, speaking to reporters during a visit to Berlin, said fighting global warming was a "global consensus" and an "international responsibility."
Without mentioning the US specifically, Li said that "China in recent years has stayed true to its commitment" and pointed out that his was one of the first countries to ratify the 2015 Paris Agreement.
German Chancellor Angela Merkel, who has in the past even been dubbed the "climate chancellor" for her efforts to fight global warming, welcomed Li's remarks at their joint press conference.
Other European leaders issued more explicit appeals to the US government not to abandon international measures against climate change.
"Please don't change the (political) climate for the worse," European Council President Donald Tusk tweeted.

Trump is expected to announce his decision on Thursday afternoon at 3:00 pm EDT (1900 GMT).
British Foreign Secretary Boris Johnson said Britain would continue to press the US to reduce dangerous emissions even if Trump pulls out.
Johnson told Sky News that Britain still wants the US to take the lead in fighting climate change and called on individual US states to keep making progress on that front.
"We will continue to lobby the Americans and the White House to show the leadership they have shown in the past on reducing CO2," he said.
Withdrawing would leave the United States as one of just three countries outside the landmark 195-nation Paris 2015 agreement to try to slow global warming. The other two are Syria and Nicaragua.
The US would also isolate itself from a raft of international allies who spent years negotiating the 2015 agreement to fight global warming and pollution by reducing carbon emissions.
While traveling abroad last week, Trump was repeatedly pressed to stay in the deal by European leaders and Pope Francis.
Russia joined the chorus speaking out in favour of the climate accord. Speaking to reporters on Thursday, a spokesman for President Vladimir Putin said Russia "thinks highly" of the accords and sees no alternative to it. Spokesman Dmitry Peskov added that its implementation will not be as effective "without the key signatories."
During a trip to Europe this week, Indian Prime Minister Narendra Modi expressed India's commitment to fighting climate change and said it would be a "crime" to spoil the environment for future generations.
Martin Schulz, a former European Parliament president who is hoping to unseat Merkel in Germany's upcoming general election, said he hoped Trump would think better of withdrawing from the accord.
Balance out economic advantage
If the US does leave, he said, the EU should seek ways to balance out the economic advantage that US companies might have from the absence of climate regulations.
"Those who want to export their goods and services to our market also have to accept our standards," he said.
Scientists say Earth is likely to reach more dangerous levels of warming sooner if the US retreats from its pledge because America contributes so much to rising temperatures.
Calculations suggest withdrawal could release up to 3 billion additional tons of carbon dioxide a year — enough to melt ice sheets faster, raise seas higher and trigger more extreme weather.
