most notably in the USA   but with similar patterns in Canada  . Vocal groups can affect public discourse and weaken public support for climate mitigation and adaptation policies  . Vested economic and political interests have organised and financed misinformation and 'contrarian' climate-change communication . Traditional media-print and broadcast-frame and transmit climate-change information and play a crucial role in shaping public perceptions, understanding and willingness to act . The journalistic norm of 'balance'  biases coverage by unevenly amplifying certain messages that are not supported by science, contributing to politicisation of science, spreading of misinformation and reducing public consensus on action . Much online social media discussion of climate change takes place in 'echo chambers'-a social network among like-minded people in communities dominated by a single view that contributes to polarisation  and the spread of misinformation .
