A global poll of 75,000 participants published Thursday revealed that every four out of five people want stronger national commitments to addressing climate change.
The survey by the U.N. Development Program, Oxford University and GeoPoll posed 15 questions by randomized telephone calls to people in 77 countries representing 87% of the world's population.
The key finding was that 80% of respondents want their governments to increase efforts to fight against global warming.
Poorer countries beat this drum the loudest, with 89% in favor, though appetite is also high in the wealthy G-20 nations (76%), according to the survey.
China (73%) and the United States (66%) – the world's biggest greenhouse gas emitters – also saw a majority of respondents in favor of climate action.
"As world leaders decide on the next round of pledges under the Paris Agreement by 2025, these results are undeniable evidence that people everywhere support bold climate action," said Cassie Flynn, UNDP global climate director.
A majority of respondents in 62 of the 77 countries surveyed said they supported a quick transition away from fossil fuels to clean energy.
These included China (80%) and the United States (54%), but in Russia just 16% of poll participants were in favor.
Worries about global warming have also increased, the survey found, with 56% saying they think about climate change at least once a week.
Over half (53%) of those surveyed said they were more worried about climate change than last year, compared with 15% who said they were less worried.
Leading the rise in climate anxiety is Fiji, where 80% are more concerned compared to a year ago, followed by Afghanistan (78%) and Türkiye (77%).
Saudi Arabia saw the lowest increase in climate fears, with 25% more worried, followed by Russia (34%), Czech Republic (36%) and China (39%).
More than two-thirds of survey respondents (69%) said that global warming had impacted their life decisions, such as where to live or work and what to buy.
However, Achim Steiner, head of the UNDP, said these concerns do not necessarily translate into electoral and consumer decisions.
"I would do more. But the others won't. So I will not do anything," Steiner said of what he called people's "perception gap" on climate action.
