Introduction
摘要
Fossil fuel combustion, industrial activity, deforestation and transportation have all been major contributors to the rise in greenhouse gas emissions since the industrial revolution. The (almost unanimous) scientific consensus is that this increase in emissions contributes to climate change and the accelerating increase in average surface temperatures (Intergovernmental Panel on Climate Change [IPCC], 2014). From the mid-20th century until the present, human activity accounts for approximately 1.0°C of global warming.
