Interest in climate change fell from 80% of respondents in 2006, to 71% last year and now stands at only 62%.
The number of climate change agnostics – those unsure whether human activity is warming the planet – has risen from 25% in 2007 to 33% now.
How many of those 33% are in the interested category? I would guess a fair percentage as unsureness is a rational response to an interest. The more you learn the less certain you can become. It is knowing the things we don't know, rather than the cockiness of a prejudice.
