Abstract

Limiting global warming requires that net emissions of greenhouse gases ultimately be reduced to zero. It is becoming increasing probable that â�?�?negative CO2 emissionsâ�? will be required to limit global warming to 20C. I will discuss this thesis, various approaches to negative CO2 emissions, the scientific challenges associated with these approaches and offer a prognosis.
