The COP21 talks continue in Paris this week, aiming to negotiate an international agreement on climate change. While Democrats and Republicans are at opposite ends of the spectrum in prioritizing climate change, Chicago Council Surveys going back to 2002 have shown longstanding public support for an international treaty to address the problem. And while still a minority, an increasing percentage of Americans support taking immediate action on climate change.
 

Nearly four in ten Americans (37%), an increase of eight percentage points since 2010, say that climate change is a serious and pressing problem, and that we should begin taking steps now even if this involves significant costs. Both Democrats and Independents have become more likely to support immediate action on climate change over the past five years. In 2010, only a plurality (49%) of Democrats favored immediate action on climate change; today, a majority (56%) believe we should. Independents have seen an even bigger shift: today, four in ten (40%) support taking steps on climate change now, up from only two in ten (23%) in 2010. Most Republicans remain split over whether the problem of climate change should be dealt with gradually (43%), or whether climate change is really a problem (44%)—a position shared by few Democrats (13%) and Independents (22%).
