Title: Pathways to net-zero carbon emissions


Biography: Douglas Ray


Limiting global warming requires that net emissions of greenhouse gases ultimately be reduced to zero. It is becoming increasing probable that “negative CO2 emissions” will be required to limit global warming to 2o C. I will discuss this thesis, various approaches to negative CO2 emissions, the scientific challenges associated with these approaches and offer a prognosis.
