Scientists Urge Stronger Paris Agreement Pledges to Curb Climate Change Reuters WASHINGTON - The vast majority of national commitments in the 2015 Paris Agreement are inadequate to prevent the worst effects of global warming, scientists said on Tuesday, naming the world's biggest greenhouse gas emitting countries as among those that must ratchet up their efforts. "Governments are moving in the right direction, but nowhere near enough, so hopefully they will be willing to take on much stronger commitments" in next month's United Nation's climate summit in Spain, said Robert Watson, lead author of the report by the nonprofit Universal Ecological Fund. The report ranked nearly 75%, or 136, of the pledges as insufficient, including ones by major carbon emitters China, the United States, and India. A dozen, by countries including Australia, Japan and Brazil, were judged only partially sufficient. Countries at next month's summit in Madrid will hash out some details of the international pact to curb warming. Chile withdrew as host following weeks of riots protesting inequality. .
