President Donald Trump's skepticism of climate change has officially made him a global outlier, as other world nations formally signaled their firm commitment to the Paris Agreement while the US continues to debate a position.

Leaders of the world’s leading economies meeting in Italy for the annual Group of Seven (G7) summit will leave the Sicilian town of Taormina divided on the issue of climate change.

"The United States of America is in the process of reviewing its policies on climate change and on the Paris Agreement and thus is not in a position to join the consensus on these topics," reads a statement the seven countries signed.

"Understanding this process,theHeads of State and of Government of Canada, France, Germany, Italy, Japan, and the United Kingdom and the Presidents of the European Council and of the European Commission reaffirm their strong commitment to swiftly implement the Paris Agreement."

German chancellor Angela Merkel described the climate talks as “very unsatisfactory”. Leaving the G7 summit she said there was no indication that the US will stay in the Paris agreement, adding that the agreement was so important that there shouldn’t be compromises.

French President Macron said Trump listened to arguments that it was essential for international equilibrium and US reputation that it remains committed to Paris accords, according to the Guardian.

Meanwhile, President Trump tweeted Saturday that he will make a final decision on the future of the US involvement in the Paris Accord next week.
