ABSTRACT

The Earth’s climate has always changed, but in recent years humans have had a clear impact on global temperatures through our use of the Earth’s resources to support industrialisation. This chapter presents recent evidence for the anthropogenic impact on the global climate, and considers some of the policy responses and challenges around mitigating that impact. It also briefly highlights the role of coupled climate and economic models, and argues that a reliance on the models’ technical solutions, such as the large-scale deployment of ‘negative emissions technologies’, potentially delays operationalising other solutions with a greater social or demand-side emphasis.
