Of this sample of the world’s population, eight out of 10 think “human activity, including industry and transportation, is a significant cause of climate change”.
Strangely 9 out of 10 of those surveyed think action is necessary to combat global warming, which would seem to imply that at least 600 million people (one in ten of the world’s population) believe we should be actively attempting to change our climate against natural processes.
I’m in the 2%.
