It's impossible for the US public to change their mind quickly as a whole. Would you disagree if I said that the US public is the public that is the most affected in the world by corporate media and marketing? Even prescription drugs are advertised here and it's rather shocking to realise that's just normal here. Similarly, greenwashing and lobbying really work and have impact on the US public. Nearly half of the US public don't believe in man-made global warming, a striking difference from the 97% consensus among climate experts [1]. You must ask yourself where this gap comes from? Big oil is and will be doing everything to slow down the public from going away from fossil fuels and the US system is built do support big corporate money.
