In the context of Trump's scepticism towards climate change phenomena, Kerry also noted that failing to fight climate change would be a "moral failure" when many countries across the globe, including the US, India and China, have already been facing a devastating consequences of global warming caused by the use of fossil fuel.

Referring to the huge clean energy market, the secretary of state said that the nations would "miss out if they sit on sidelines. He said, "The US on way to meeting all of international targets set. I don't believe that can or will be reversed" -- a remark on the speculations over the country's action under Trump who had during his campaign even threatened to withdraw from the Paris Agreement.

"Since this cop started, obviously an election took place in my country. And I know it has left some here and elsewhere feeling uncertain about the future. I obviously understand that uncertainty. And while I can't stand here and speculate here about what policies our president-elect will pursue, I will tell you this: the time that I have spent in public life, one of the things that I have learnt is that some of the issues look a little bit different when you are actually in office compared to when you are on the campaign trail", said Kerry in a clear reference to what Trump had said during his campaign for the presidential election.

Emotional Kerry, who had been actively involved with the processes to arrive at a global deal in the French capital last year, also sought to put a kind of pressure on Trump while mentioning how the air pollution caused by use of fossil fuel had not only affected millions of people in China and India but also the US where air-pollution linked asthma caused taxpayers more than 55 billion dollars annually. He was speaking here at the UN climate change conference.

Highlighting those health-related issue in the US, China and India, he said no one had a right to take decisions that affect billions of people based solely on ideology or without proper input. "For those in power in all parts of world including my own, I ask you see for yourself before making irrevocable choices...Wise public policy demands that we take precautionary measures now".

"At some point, even the strongest sceptic has to acknowledge that something disturbing is happening", Kerry said while referring to many extreme weather events across the globe and the WMO's latest report that talked about the constant temperature rise, making 2016 the hottest year on record.

UN chief Ban Ki-moon, too, had raised such issues here on Tuesday and expressed his hope that the US President-elect would see reasons in not derailing the climate-friendly process initiated by the nations from across the globe.

"I am sure that he (Trump) will understand this, he will listen, he will evaluate his campaign remarks. We have seen many such campaign rhetoric not only in the United States but in many parts of the world", said the UN chief while responding to a question in his first post-US election press conference here on Tuesday.

Since Trump had on social media called climate change and global warming a "hoax" and threatened to withdraw from the Paris Agreement, there has been a lot of apprehension over the fate of the global deal here during the on-going climate change conference (COP22). Remarks of Kerry and Ban Ki-moon can obviously be read in that context even as Trump himself has so far not opened his mouth on the issue after being elected as the next US president.
