'Scientific and political awareness of the greenhouse effect and human influence on the climate has existed for over three decades. During the 1980s, there was a strong environmental movement and a political consensus on the issue, but in recent years, climate change denial – denying that changes to the climate are due to human influence on the environment – has increased which makes the case for understanding why this is so.'
