https://www.youtube.com/watch?v=9TMIDopkdlU I wrote in an article about the latest New York Times/CBS News poll that one of the biggest divides in the United States around climate science is political: 90 percent of Democrats polled said that global warming would have a serious effect on the earth, compared with 58 percent of Republicans. Latinos and African-Americans are more likely than whites to say that climate change is having an effect, and women are more likely than men, according to the poll. Three-fourths of Hispanics said that global warming was caused by human activity such as burning fossil fuels, compared with 57 percent of blacks and 46 percent of whites. And 58 percent of Hispanics and 49 percent of blacks said they worried at least a fair amount about climate change. Only 38 percent of whites said that they did. Half of American women said they worried, compared with 38 percent of men. Thinking about the effects of global warming, 56 percent of women said it was having a serious effect already. Just 44 percent of men agreed. Internationally, those in the developing world appear to be most concerned about climate change. According to Pew’s most recent Global Attitudes survey, released in the spring, just 45 percent of Americans and 54 percent of Europeans consider climate change a “very serious problem.” Almost three-quarters — 74 percent — of those in Latin America and 61 percent of respondents in Africa said the same.
