            In 2014 and 2015,a Gallup World Poll surveyed people m 119 countries. A group of scientists analyzed how people answered two of the questions: How much do you know about global warming,and how serious was it to you and your family? And they were surprised.

            Most scientists think the world's  climate changing fast,yet many people do not share the scientists,view.What's  more,how people responded depended on various reasons. These included where people livd,how;many years they'd  gone to school,how much money they earned,their gender — even things such as how polluted the air was in the place where they lived. It's the first time those have been studied for their possible link to people' s thoughts on climate change.

            Many people were not even aware of global warming. Most people in Africa and the Middle East had!never heard of the concept. In contrast,people in the wealthier and more highly educated nations were quite familiar with global warming. Among people who were : aware of global warming,those in the poorer nations i tended to judge it as a far bigger threat. And in Latin Amenca and Europe people were more likely to see global warming as a bigger menace (威胁) when they understood the role that humans have played in that : warming. In Africa people were more likely to see :

climate change as a risk if it was tied to local temperatures or air pollution.

          “To our knowledge,this is the first and only truly global study,”according to the study's  lead author Lee.; Lee says the new analysis indicates that there's  still much work to do to get the word out about global warming. Indeed,helping people in different parts of the globe  understand it may require explaining the data and risks in;very different ways. Those explanations might have to differ from one neighboring country to another.
