UN Secretary-General Ban Ki- moon said on Friday that the world should respond quickly and decisively towards the climate change.

In a statement issued by his spokesperson, Ban welcomes the important findings of the Working Group 1 contribution of the Intergovernmental Panel on Climate Change (IPCC) released in Paris.

He congratulated the panel of independent climate scientists and experts, who have "deepened our understanding of the changes that are affecting the global environment and the human causes at their root."

"The report highlights the scientific consensus regarding the quickening and threatening pace of human-induced climate change," Ban said, stressing that "the global response therefore needs to move much more rapidly as well, and with more determination."

"Today's study, and the follow-up reports of the IPCC during 2007, will be critical guides for the UN's response to anthropogenic climate change, and undoubtedly will assist many other stakeholders in taking actions at the global, national and local levels," the Secretary-General concluded.

It was very "likely" that human activities led by burning fossil fuels had facilitated the warming in the past half century, said the final text of the report issued by the IPCC, world's most authoritative group on the study of global warming.
