Say we will emit a certain amount of greenhouse gas over the next 50 years (e.g. 100 billion tons CO2-eq in total). What would happen if I implement a certain GHG mitigation effort to cut the same amount of GHG (say sequester 20 billion tons CO2-eq) in the early years (e.g. year 0-10) vs in later years (year 40-50)?
I would imagine that cutting the gas earlier would be better since overall global warming is a cascade of positive feedbacks? A bunch of other similar questions can be asked like cutting the same amount of GHG over first 10 years (but no cutting thereafter) vs spread out the cutting to the entire 50 years. What are some major consideration to look at? Is it generally better to cut GHG as early as possible?
