(CNN)Nearly two-thirds of respondents believe that climate change is a "global emergency," according to a survey of 1.2 million people in dozens of countries around the globe -- and many want urgent action to tackle the problem.
Almost two-thirds of people believe climate change is a global emergency, UN poll finds
The United Nations Development Programme (UNDP), which ran the poll with Oxford University, described it as the largest survey of public opinion on climate change ever conducted. Unusually, it captured the views of more than half a million people under the age of 18, a key but typically hard-to-reach constituency, the organization said.
The "Peoples' Climate Vote" was undertaken late last year in 50 high, middle and low income countries that together account for more than half of the world's population over the age of 14, according to the UNDP report.

Respondents were asked where they would most like to see action, with questions on support for 18 policy options across six areas -- energy, economy, transportation, farms and food, protecting people, and nature.
Four climate policies emerged as the most popular globally, with 54% of those surveye
