"As a new Pew Research Center survey illustrates, there is a global consensus that climate change is a significant challenge. Majorities in all 40 nations polled say it is a serious problem, and a global median of 54% consider it a very serious problem. Moreover, a median of 78% support the idea of their country limiting greenhouse gas emissions as part of an international agreement in Paris."
