Two in three Californians say the effects of global warming are already occurring.
Two-thirds of Californians (67%) say global warming’s effects have already begun, and one in five (20%) say the effects will begin in the future. Only 8% say the effects will never happen. Since 2005, when PPIC began asking this question, majorities have said the effects have already begun. Today, majorities across regions and age, education, gender, and income groups hold this view. Asian Americans (78%) are the most likely to say the effects have already begun, while whites (12%) are the most likely to say the effects will never happen. A similar proportion of adults nationwide (60%, March 2018 Gallup Poll) say the effects have already begun.
Most Californians are concerned about the impact of global warming.
Most Californians (80%) view global warming as a very serious (56%) or somewhat serious (24%) threat to the state’s future economy and quality of life. At least half across age, education, gender, income, and racial/ethnic groups see global warming as a very serious threat. Democrats (76%) are three times as likely as Republicans (22%) to hold this view. More than eight in ten Californians across regions and demographic groups are very or somewhat concerned about more severe wildfires caused by extreme weather, a possible impact of global warming. More than seven in ten Californians are very or somewhat concerned about ocean warming affecting marine and coastal life (78%) and rising sea levels having an impact on flooding and beach erosion (74%). On both issues, concern is higher among Democrats than among Republicans.

Most Californians support state efforts to address global warming.
In PPIC surveys from 2006 to 2016, strong majorities of Californians favored the state’s landmark law limiting greenhouse gas emissions (Assembly Bill 32). Today, 67% said they favor the more ambitious goals set by Senate Bill 32. Across racial/ethnic groups, Latinos (73%) are the most likely to be in favor while whites (64%) are the least likely. When asked about a proposed state law that would require 100% of the state’s electricity to come from renewable energy sources (Senate Bill 100), 72% of Californians are in favor, while 21% are opposed. At least six in ten across regions and demographic groups are in favor of both policies.
Majorities support action on climate change even if it brings increased costs.
Half of Californians (50%) say they would be willing to pay more for electricity generated by renewable sources to reduce global warming. When asked how state action to reduce global warming might affect gas prices, a majority of Californians (56%) say they expect prices would increase. Half of Californians (48%) believe that state policies to combat global warming would cause there to be more jobs around the state, while 18% would expect fewer jobs; 23% think there would be no effect.
Most Californians say the issue of global warming is personally important.
Most Californians (62%) say the issue of global warming is important to them personally (28% extremely important, 34% very important), compared to 48% of adults nationwide (June 2018, ABC News/Stanford/ Resources for the Future Poll).
