A late April 2015 Frontlines poll of more than 1001 respondents in each of 9 countries (9000+ total sample size) by the International Trade Union Confederation found:
90% of respondents want to see leaders take action to prevent the world’s population from being impacted by climate change. In the US it was 69%.
79% want action in the next 12 months or less. In the US 55% wanted action within 12 months or less, in developed countries 69%.
Most tellingly, just 4% indicated that they thought that the world’s leaders do not need to act. In the US it was 15%, In developed countries 7%.
