US President Donald Trump has indicated that he can change his stand on Paris Climate accord. Addressing a joint press conference after talks with his French counterpart Emmanuel Macron, he said something can happen regarding the climate change deal. <br/><br/>The US President has opened the door to a reversal of his decision barely six weeks after announcing that the United States will abandon the 2015 pact. <br/><br/>Nearly 200 countries signed Paris agreement in December 2015 in an effort to combat global warming and help poorer countries adapt to an already-changed planet. <br/><br/>Trump, whose country is the world's second biggest producer of greenhouse gases after China, drew widespread criticism when he announced on June 1 that he will quit the pact. Mr Trump is on a visit to France for Bastille Day.
