Climate change is the greatest challenge humanity faces in the 21st century. Global mean surface temperature has increased by 1.2C since the beginning of industrialization, driven by fossil fuel burning and land use change. The Intergovernmental Panel on Climate Change has proposed to limit global warming to within 1.5-2C, beyond which many tipping points in the Earth system would be reached and cause irreversible damages. This course will examine potential solutions to mitigate climate change.
